Description

Power protection groove of hilly area quick construction

Technical Field

The invention relates to an electric power protection groove for rapid construction in hilly areas.

Background

With the gradual improvement of urban power supply quality requirements, the conversion from high-voltage overhead line power supply to underground high-voltage power supply is basically completed in the current urban high-voltage power supply mode in China. The underground high-voltage power supply mainly comprises two modes of underground pipeline high-voltage power supply and underground groove high-voltage power supply. The high-voltage power supply of the underground groove needs to lay a high-voltage cable groove for containing a high-voltage cable underground.

The electric power system makes an industry construction regulation for laying a high-voltage cable groove, and specifically comprises the following steps: 1. the cable climbing tower and other places need to increase the burial depth reasonably according to the specific conditions on site. So as to meet the turning radius requirement of the cable; 2. burying a cable path marking tape in a path 300mm below the ground, wherein the width of the cable path marking tape is 1300 mm; 3. the turning radius of cable laying is not less than 20 times of the outer diameter of the cable; 4. if the optical cable needs to be laid, the turning radius of the optical cable is not less than 3 m; 5. the operation is executed according to the current relevant construction specifications.

The traditional high-voltage cable groove is built on site by adopting clay red bricks and cement mortar. The traditional high-voltage cable groove has the defects that the main material of the masonry is solid clay red bricks, the solid clay red bricks occupy a large amount of cultivated land due to the production, consume energy, are non-degradable resource consumption finished products, are gradually limited or even forbidden to be used by large, medium and small cities, and the cable groove is built on site, so that various raw materials are not easy to manage, the engineering construction efficiency is low, the construction period is long, and the cost is high. The traditional high-voltage cable groove has the advantages that the groove can be made into any required shape and bending degree, and the groove has the advantage of completely meeting the construction requirements.

The prefabricated high-voltage cable groove appears in the current market, mainly comprises an integrated groove body with two parallel and level ends, the groove body mainly comprises a bottom plate, and the left side and the right side of the bottom plate are respectively and fixedly provided with side plates extending upwards to form an upward U-shaped groove of an opening part, so that the structure is very simple. When in use, all the groove bodies are only paved in the dug trench end to end and covered firmly by the cover plate, and the operation is very simple. However, the high-voltage cable groove has the disadvantages that 1, the high-voltage cable groove is only suitable for laying a straight cable groove, when the cable groove turns, the high-voltage cable groove can only be turned at right angles, if the turning radius requirement specified by construction in the power industry is met, the prefabricated high-voltage cable groove is cut and shaped on site, so that all the prefabricated high-voltage cable grooves at the turning part are butted and level, the field processing difficulty is high, and time and labor are wasted; or gaps are reserved among all prefabricated high-voltage cable grooves at the turning positions to meet the turning requirements, but water and soil leakage at the gaps inevitably occurs after the cable grooves are used, and finally, the cable grooves are filled with silt, so that the construction requirements are not met, and troubles are brought to cable maintenance and transformation in the future; 2. the cross section of the prefabricated high-voltage cable groove is in a U shape, so that the prefabricated high-voltage cable groove occupies a large space, is extremely inconvenient to transport and store, and has small impact resistance and easy stress and damage; 3. the prefabricated high-voltage cable groove is not internally provided with a spacing device, and three single-core cables are laid in the same groove, so that the contact between cable phases can be made, and cable accidents are easily caused; 4. when a groove line turns, gaps with different sizes can be formed at the joint of the grooves of the prefabricated high-voltage cables, gap filling construction needs to be additionally carried out on site, otherwise, soil flows into the groove cavity to leak soil and mud, and the use safety of the cable or the optical cable in the groove is seriously affected.

The existing part of design construction units also use on-site precast concrete grooves, and the bottom grooves and the cover plates can be exposed due to the fact that concrete layers are damaged due to the brutal use during hanging and unloading in the construction process, so that when the cover plates are in contact with the concrete grooves below, closed magnetic loops are formed on the single-core cables, and the single-core cables are damaged due to eddy currents.

Disclosure of Invention

The invention aims to solve the technical problem of providing the power protection groove which is reasonable in structure, can be laid along a straight line in an extending mode, can be laid in an arc mode at any time and any place according to turning requirements, is tight in connection, has no gap, does not need to fill gaps, is smooth in transition, simple and quick in construction and construction, convenient and efficient in disassembly and maintenance, high in cable phase safety, small in storage and occupied space, convenient to transport and not prone to damage, and is used for rapid construction in hilly areas.

In order to solve the technical problem, the structural characteristics of the electric power protection groove for rapid construction in the hilly area are as follows: the long side hole and the short side hole are symmetrically arranged relative to a middle line between the short side and the long side; when two bottom plates are butted in a long edge mode according to the short edge of one bottom plate and another bottom plate, the distance between the two corresponding adjacent short edge holes and the long edge holes of the butted part is equal to the distance between the two short edge holes on the same bottom plate, stand columns are inserted in the short edge holes and the long edge holes, short edge plates are arranged on the short edge parts, long edge plates are arranged on the long edge parts, the bottoms of the short edge plates and the long edge plates are provided with stand column holes corresponding to the stand columns in insertion fit, two positioning grooves which are arranged in parallel with the short edge are arranged on the bottom plates, the two positioning grooves are symmetrically arranged relative to the middle line between the short edge and the long edge, a partition plate which extends upwards is inserted in each positioning groove, cover plates which are consistent with the shape of the bottom plates are buckled on the upper parts of the short edge plates and the long edge plates, end holes are arranged at the two end holes in the end holes, end hole.

In the invention, the power protection groove for rapid construction in hilly areas mainly comprises a bottom plate, short side plates, long side plates, partition plates, upright columns and cover plates. Wherein, the bottom plate is the core part of this hilly area quick construction's electric power protection groove, and its main function does not but provide the support for other parts, and more importantly has played direction or directional effect to the direction of laying of whole hilly area quick construction's electric power protection groove circuit. In this electric power protection groove of hilly area quick construction, the direction or the directional action of bottom plate to the electric power protection groove circuit of whole hilly area quick construction is not accomplished by workman field design, but relies on the structural feature of bottom plate self to realize. In this hilly area rapid construction's electric power protection groove, the bottom plate is isosceles trapezoid structure, and its four limits are minor face, long limit and two waist limits respectively, and wherein the minor face is than long limit short and both parallel arrangement, and two waist limits are along the mid point line symmetry setting on minor face and long limit.

For convenience of description, the placement of the short edges to the right and left long edges when the bottom plate is laid in the groove is called forward or forward placement, and the placement of the long edges to the right and left short edges is called reverse or reverse placement. When the route that need be with the electric power protection groove of hilly area quick construction extends along the straight line, need align the waist limit of two bottom plates to with two adjacent bottom plates reverse placement, that is to say one forward place one backward and place, or one backward place one forward and place, analogize in proper order. When the two adjacent bottom plates are reversely placed, the adjacent waist edges of the two adjacent bottom plates are aligned, the short edge of one bottom plate is in butt joint with the long edge of the other bottom plate, and the long edge of one bottom plate is in butt joint with the short edge of the other bottom plate. For convenience of description, the placing manner is a straight line placing manner or a straight line state. The theoretical basis is that in a linear state, the left sides of two adjacent bottom plates are short edges connected with long edges, and the right sides of the two adjacent bottom plates are long edges connected with short edges. In the isosceles trapezoid structure of the bottom plate, the included angle between the long side and the waist side is an acute angle, the included angle between the short side and the waist side is an obtuse angle, and the sum of the acute angle and the obtuse angle is just 180 degrees. In the linear state, the adjacent waist edges of the two bottom plates are aligned together, and the long edges and the short edges of the two bottom plates are butted together, that is, an obtuse angle and an acute angle of the two bottom plates are butted together, and obviously, the sum of the two bottom plates is also 180 degrees, that is, the included angle between the short edges and the long edges of the two bottom plates which are butted together is 180 degrees, that is, a straight line.

When needs turn round, that is when needs turn to, need align the adjacent waist of adjacent bottom plate to place two adjacent bottom plates syntropy, also be that either two adjacent bottom plates are all forward to be placed, or two adjacent bottom plates are all reverse to be placed, analogize in proper order. The meaning of equidirectional placing is that the adjacent waist edges of the adjacent bottom plates are aligned, the long edge of one bottom plate is butted with the long edge of the other bottom plate, and the short edge of one bottom plate is butted with the short edge of the other bottom plate. For convenience of description, this placement mode is referred to as a turning placement or turning state. The theoretical basis is that when the automobile seat is in a turning state, any side of two adjacent bottom plates is the side edge of the bottom plate in the same type, namely, when the automobile seat turns leftwards, the left side is short edge connected short edge, the right side is long edge connected long edge, when the automobile seat turns rightwards, the left side is long edge connected long edge, and the right side is short edge connected short edge, so that no matter whether the automobile seat turns leftwards or rightwards, the two adjacent bottom plates are symmetrically arranged by taking the aligned waist edge as a symmetrical line; because the included angle between the waist edge and the long edge of the bottom plate is an acute angle, namely the included angle between the long edges of two adjacent bottom plates is the sum of two acute angles which are necessarily less than 180 degrees, the long edges of the two bottom plates are in different directions, namely are turned or turned. The turning angle or inclination angle of the two bottom plates is the difference between the included angle of the two butted long sides and 180 degrees, the numerical value of the turning angle or inclination angle is also equal to twice the difference between the acute angle and the right angle between the waist side and the long side, for convenience of description, the acute angle included angle between the waist side and the long side is called a waist angle, and the difference between 180 degrees and the twice value of the waist angle is called a two-body turning angle or turning angle. When a third bottom plate is placed in the subsequent same direction, the included angle between the long edge of the third bottom plate and the long edge of the first bottom plate is twice of the two-body steering angle, namely, the power protection groove circuit which is rapidly constructed in the whole hilly area turns to twice of the two-body steering angle; when a fourth bottom plate is placed in the same direction subsequently, the included angle between the long edge of the fourth bottom plate and the long edge of the first bottom plate is three times of the two-body steering angle, namely, the power protection groove circuit which is quickly constructed in the whole hilly area turns to three times of the two-body steering angle, and so on until the required steering angle is reached. In practical application, because the included angle between the waist edge and the long edge is generally set to be an acute angle with a larger value, the numerical value of the steering angle of the two bodies is smaller, namely the steering angle of each subsequent bottom plate is very small, so that the purpose of steering at a large angle (such as 90 degrees) can be achieved by placing the subsequent bottom plates in multiple directions, and the steering of the power protection groove for rapid construction in the hilly area is very smooth and is particularly suitable for underground laying engineering of single-core cables and optical cables.

Be equipped with two short limit holes on the short limit portion that is close to the minor face on the bottom plate, the downthehole cartridge of minor face has the stand of vertical setting, and it is downthehole that the minor face is arrived in the lower half cartridge of stand, and the short limit hole is exposed in the first half of stand. Short side plates are further placed on the short side parts and extend upwards. The bottom of the short edge plate is provided with a stand column hole, and the stand column hole is correspondingly inserted and matched with the upper parts of the two stand columns on the short edge part. Therefore, the short side plate passes through the upright column and the short side hole and the upright column hole which are vertically inserted and matched with the upright column, so that the short side plate is connected with the short side part of the bottom plate, the short side plate and the short side part of the bottom plate are positioned, and the position relation between the short side plate and the bottom plate is fixed and unique.

Similarly, two long edge holes are formed in the long edge part, close to the long edge, of the bottom plate, vertical stand columns are inserted into the long edge holes, the lower half portion of each stand column is inserted into the corresponding long edge hole, and the long edge holes are exposed out of the upper half portion of each stand column. The long edge plate is also placed on the long edge part of the bottom plate, and the long edge plate extends upwards. The bottom of the long edge plate is provided with a stand column hole, and the stand column hole is correspondingly inserted and matched with the upper parts of the two stand columns on the long edge part. Therefore, the long-edge plate is connected with the short-edge part of the bottom plate and positioned between the long-edge plate and the short-edge part of the bottom plate through the upright column and the long-edge hole and the upright column hole which are vertically inserted and matched with the upright column, so that the position relation between the long-edge plate and the short-edge part of the bottom plate is fixed and unique.

After the long side plate and the short side plate are positioned on the base through the upright posts, the short side plate, the long side plate and the base plate are quickly erected into a cable groove with a U-shaped cross section, and the single-core cable, the optical cable and the like are laid in the cable groove, so that the protection effect on the single-core cable and the optical cable is achieved.

In this electric power protection groove of hilly area quick construction, short limit hole and long limit hole are for the intermediate line symmetry setting between minor face and the long limit, that is to say, short limit hole and long limit hole size are the same, the interval of two short limit holes is isometric with the interval of two long limit holes, the interval of two short limit hole distance minor faces is the equidistance with the interval of two long limit hole distance long limits, short limit hole and long limit hole are the alignment about.

In this hilly area rapid construction's electric power protection groove, when placing two bottom plates reverse, and the waist of two bottom plates is when aliging, also is that a bottom plate forward places a bottom plate and places in reverse, also is that the minor face of a bottom plate docks the long limit of another bottom plate, and the long limit of a bottom plate docks the short limit of another bottom plate during. The interval between the adjacent short side hole and the long side hole corresponding to the two sides of the butt joint part (namely, the butt joint of the coincident waist edges) is equal to the interval between the two short side holes on the same bottom plate, namely, the connecting line tracks of the two short side holes and the two long side holes on the same side after the two bottom plates are in butt joint are located on the same straight line, and the intervals of any two adjacent same side holes in the four same side holes are equal. The purpose that sets up like this is, no matter short sideboard or long sideboard can both pass through the stand cartridge on arbitrary two adjacent same side openings on two bottom plates after the butt joint, that is to say, short sideboard and long sideboard not only can pass through the stand cartridge on solitary bottom plate, also can pass through the stand cartridge on two same side openings that are close to butt joint portion. Obviously, when the short side plate or the long side plate is inserted on the separate bottom plate through the upright post, the short side plate or the long side plate is carried by the bottom plate separately. And when short sideboard or long sideboard pass through the stand cartridge when on two with the side opening near butt joint portion, this short sideboard or long sideboard then bear by two bottom plates of this butt joint jointly, at this moment, because the location connection relation of stand, this short sideboard or long sideboard still have the effect of this two butt joint bottom plates of fixed connection, make each butt joint bottom plate rigid coupling in proper order together, the cohesion or the joint force on each bottom plate length direction have been strengthened, the structural stability of the electric power protection tank circuit of whole hilly area quick construction has effectively been guaranteed, be particularly suitable for in geology soft, yielding or unstable area and seismic region use.

The bottom plate is provided with two positioning grooves which are arranged in parallel, the positioning grooves are arranged in parallel with the short edges, and the two ends of each positioning groove are communicated with the waist edges. In this electric power protection groove of hilly area quick construction, two constant head tanks are relative to the mid line symmetry setting between minor face and the long limit, that is to say that two constant head tanks apart from the minor face or the distance on long limit that respectively close to are equal. The purpose that sets up like this, no matter two adjacent bottom plates are that the syntropy is placed or reverse placing, can both guarantee that two constant head tanks correspond to dock together. The baffle plate which extends upwards is inserted in the positioning groove, and the baffle plate is mainly used for separating electric power cables and communication cables such as single-core cables, optical cables and the like laid in the cable groove, particularly three-phase single-core cables, so that the phenomenon of interphase short circuit is fundamentally avoided. The short side plate and the long side plate are buckled with a cover plate which is consistent with the bottom plate in shape, after the cover plate is buckled, the cable groove and the cover plate form a cable tube which can be quickly disassembled and assembled, and the cable or the optical cable to be laid can be reliably protected in the upper, lower, left and right directions. The cover plate is arranged to be consistent with the bottom plate in shape, so that when the cover plate is arranged to correspond to the bottom plate up and down, the cover plate can extend correspondingly along with the straight line of the bottom plate, or turn correspondingly along with the smooth turning of the bottom plate, thus the top surfaces of the cable tubes are closely butted, the phenomena of soil leakage and mud leakage after the soil is buried in the laying process are effectively avoided, and the long-term reliable operation of the laid cables or optical cables is ensured.

The power protection groove for rapid construction in hilly areas adopts a multi-component assembly structure, namely, the whole concrete groove is divided into a plurality of assembly components such as a bottom plate, a short side plate, a long side plate, a clapboard, a cover plate, an upright post and the like, and the assembly components are assembled into a cable pipe for laying cables or optical cables required by construction on site in an assembly mode. Therefore, when storing or transporting, the assembled parts can be bundled and packaged in batches, for example, a plurality of bottom plates can be bundled and packaged in batches, a plurality of short side plates can be bundled and packaged in batches, and the like. After bundling and packing, the assembly parts in the bundle or the package are tightly matched, and the gap between the assembly parts is very narrow and can be almost ignored. And present traditional prefabricated high-voltage cable slot is the integral type cavity support body structure of transversal personally submitting "U" shape, can not place anything in the cavity support body when depositing or transporting, therefore cavity support body structure has occupied a large amount of spaces, and it is big not only to deposit the area occupied, and conveying efficiency is extremely low moreover, and cavity support body structure is very easily damaged in the transportation, and the rejection rate is high, and the cost of transportation also must improve. Therefore, the electric power protection groove for rapid construction in the hilly area occupies small space, is convenient to transport, high in efficiency, low in damage rate and low in cost, and contributes to reducing the construction cost.

In this patent, be equipped with the end hole at apron length direction both ends, the effect in end hole has two, and an effect is when dismantling the maintenance, and maintainer can stretch the finger or instrument and catch on the apron inner wall in the end hole, then just can very easily take out apron from bottom to top fast, and is very simple. Because the end hole plugs are inserted in the end holes and the adjacent end hole plugs of the adjacent cover plates are connected into a whole through the elastic band, the second function of the end holes is to provide locking positions for the end hole plugs, so that the elastic band between the end hole plugs is in an elastic tensioning state, the elastic connection effect on the adjacent cover plates, namely the elastic connection effect on the adjacent cable pipes is realized, particularly when the cable pipe is used in a bent terrain or a region where soil is easy to loosen and deform, the continuity of the cable pipes can be effectively kept, and the continuity of cables laid inside is relatively protected. The elastic band is fixedly provided with a color band which has three colors of red, blue and yellow, the color band is mainly used for helping maintenance personnel to visually judge the condition of the internal cable through the color of the color band, the red color band represents that the cable joint is arranged at the position, the blue color band represents that the complete cable passes through, and the yellow color band represents that the cable is damaged or repaired at the position. In practical application, the color band can be provided with more colors, such as black, white and the like, and different identification meanings are given, so that the efficient overhaul of the electric power overhaul personnel is facilitated.

As an improvement, an extending upper extending part is fixedly arranged at the upper part of one end of a short side plate, a lower concave part is formed at the lower part of the end of the short side plate and the lower part of the extending upper extending part, a lower extending part extending is fixedly arranged at the lower part of the other end of the short side plate, an upper concave part is formed at the upper part of the end of the short side plate and the upper part of the lower extending part, the shape of the upper concave part is matched with that of the extending upper part, the shape of the lower extending part is matched with that of the lower concave part, a positioning column extending downwards is fixedly arranged at the lower end of the extending part, and a positioning hole; the one end upper portion of long sideboard sets firmly epitaxial last portion of extending, this end lower part of long sideboard and last extension portion lower part form the concave part down, the other end lower part of long sideboard sets firmly epitaxial lower extension portion, this end upper portion of long sideboard is equipped with and forms the concave part with lower extension portion upper portion, the shape of going up the concave part cooperatees with the shape of last extension portion, the shape of lower extension portion cooperatees with the shape of concave part down, it is equipped with downwardly extending's reference column admittedly to go up extension portion lower extreme, lower extension portion upper end is equipped with the locating hole with the reference column plug-in assembly.

Set up the short flange one end and prolong portion and lower concave part, the other end sets up concave part and lower concave part, and will go up to prolong portion and go up the concave part and set up the shape cooperation, set up the shape cooperation of lower concave part and lower concave part, can make two adjacent short flanges when the butt joint, the last concave part that prolongs portion and the short flange of rear of the place ahead of short flange corresponds and clamps together, the lower concave part of the short flange of place ahead also corresponds with the lower concave part of the short flange of rear and clamps together this moment, just so realized the zero clearance butt joint of two adjacent short flanges, help improving the seal of inside wall when "cable pipe" turns round, effectively prevent to bury earth behind "cable pipe" inner chamber earth leakage, leak mud phenomenon, guaranteed the cleanness of cable pipe inner chamber. Similarly, one end of the long side plate is provided with an upper extending part and a lower concave part, the other end of the long side plate is provided with an upper concave part and a lower concave part, the upper extending part and the upper concave part are matched in shape, the lower concave part and the lower concave part are matched in shape, when two adjacent long side plates are in butt joint, the upper extending part of the front long side plate and the upper concave part of the rear long side plate are correspondingly clamped together, at the moment, the lower concave part of the front long side plate and the lower concave part of the rear long side plate are correspondingly clamped together, the two adjacent long side plates are in gapless butt joint, the tightness of outer side wall connection when the cable pipe turns is improved, soil leakage and mud leakage of the inner cavity of the cable pipe after soil burying are effectively prevented, and the cleanness of the inner cavity of the cable pipe is guaranteed. Similarly, when one short side plate is in butt joint with one long side plate, the upper extending part of the long side plate is correspondingly clamped with the upper concave part of the short side plate, and the lower concave part of the long side plate is correspondingly clamped with the lower concave part of the short side plate, so that the gapless butt joint of two adjacent long side plates and the short side plate is realized, and the tightness of the cable pipe along the straight line extension is improved. In this hilly area quick construction's electric power protection groove, go up extension portion lower extreme and be equipped with downwardly extending's reference column admittedly, the lower extension portion upper end is equipped with the locating hole with the positioning column plug-in fit.

As a modification, the positioning column has an elastic rubber column which is bent and deformed.

After the elasticity that has bending deformation that will reference column design, when the earthquake or geology not hard up warp, between the short sideboard on two adjacent bottom plates, between the long sideboard, or when short sideboard and long sideboard take place the dislocation on the horizontal direction, the reference column can continue the cartridge in the locating hole, but the reference column this moment can take place elastic deformation's distortion, in order to adapt to above-mentioned dislocation, just so guaranteed when earthquake or geology are not hard up, the continuity of this hilly area quick construction's electric power protection groove circuit, avoided traditional high-pressure cable slot or prefabricated high-pressure cable slot breakage when the earthquake takes place or geology not hard up warp, hilly area quick construction's electric power protection groove circuit interrupt scheduling problem, effectively improved the electric power protection groove circuit's of hilly area quick construction connection reliability and the life-span of cable or optical cable in the hilly area.

In a preferred embodiment, the positioning column is a conical column with a thicker upper end and a thinner lower end.

After the positioning column is arranged to be a conical column with a thicker upper end and a thinner lower end, the positioning hole on the lower extension part is a conical hole with a thicker upper end and a thinner lower end corresponding to the positioning hole. Therefore, when the short side plates are in butt joint, the short side plates are in butt joint with the long side plates, and the long side plates are in butt joint with the long side plates, the thin positioning columns at the lower ends can be easily inserted into the thick positioning holes at the upper ends, and the butt joint is very quick and convenient.

As an improvement, when the short side plate and the long side plate are inserted on the corresponding side of the bottom plate through the upright post, the axial leads of the positioning post and the positioning hole are flush with the corresponding end face of the bottom plate.

When short sideboard, long sideboard corresponds the cartridge through the stand and corresponds the avris at the bottom plate, thereby when assembling into required "cable duct", set up the reference column at short sideboard and long sideboard both ends and the axial lead of locating hole just in time with bottom plate terminal surface parallel and level, also be exactly with waist limit parallel and level, can guarantee two sets of "cable ducts" no matter place the butt joint according to the forward or when placing the butt joint according to the reverse, can both guarantee the short sideboard on two bottom plates, long sideboard passes through the reference column in butt joint portion, also dock directly over the waist limit that also is in the butt joint. That is to say, with reference column, locating hole axial lead and waist limit parallel and level, can make between adjacent or butt joint's short side board and short side board, between short side board and the long side board, have "articulated" function between long side board and the long side board, make two adjacent or butt joint "cable groove" have "articulated" function promptly. The hinging function can ensure that two adjacent bottom plates are smoothly connected together through the butted short side plates and long side plates no matter the cable slot extends linearly or turns, and ensures the continuity, smoothness and integrity of the electric power protection slot line constructed quickly in the whole hilly area.

As an improvement, the upright column is a symmetrical conical column with a thick middle part and thin two ends.

After the upright column is set into a symmetrical conical column with a thicker middle part and thinner two ends, the long side hole and the short side hole on the bottom plate are conical holes with thicker upper ports and thinner inner ends corresponding to the long side hole and the short side hole, and the upright column holes at the lower ends of the long side plate and the short side plate are conical holes with thicker lower ports and thinner inner holes matched with the upper part of the upright column. Therefore, when the lower parts of the stand columns are inserted into the long side holes and the short side holes of the bottom plate, the stand columns with thin lower ends can be easily inserted into the long side holes and the short side holes with thick upper ends, and the insertion is very quick and convenient. Similarly, when the long side plate and the short side plate are correspondingly assembled to the long side part and the short side part of the bottom plate, the upright post with the thin upper end can be easily inserted into the upright post hole with the thick lower end, the overall assembly speed is improved, and the construction efficiency is improved.

For convenience of description, a bottom plate extending along a straight line of a power protection slot line constructed rapidly in a hilly area is referred to as a straight bottom plate, and a bottom plate placed in butt joint with the straight bottom plate in the same direction is referred to as a turning bottom plate. Because the last end of extending of portion is the evagination arc surface with reference column axial lead as the axial lead, the last concave end of going up the concave part is the indent arc surface with the locating hole axial lead as the axial lead, and extend end and last concave end sliding fit, consequently, when two bottom plates equidirectionally place the butt joint, namely a bottom plate is the straight line bottom plate, when a bottom plate is the bottom plate that turns round, the contained angle between the short sideboard and the short sideboard of homonymy butt joint on two bottom plates is less than 180 degrees, that is to say that both are not aligned, under the articulated cooperation of the reference column that two short sideboard correspond and locating hole like this, can form an contained angle, this contained angle is aforementioned two body steering angle promptly. Because the corresponding upward extending end face and the upward concave end face of the two butt-joint short side plates are in sliding fit around the axial lead of the positioning shaft, even if the two short side plates are in cross fit or hinged fit at a two-body steering angle, the butt-joint parts of the two short side plates, namely the upward extending end face and the upward concave end face, are still in airtight fit, the tightness of the electric power protection groove line which is quickly constructed in the whole hilly area when turning is ensured, the defect that gaps need to be filled when traditional prefabricated high-voltage cable grooves are laid is avoided, and the phenomena of soil leakage and mud leakage are fundamentally avoided. Similarly, the lower end face and the concave end face between the two butt short side plates are in close fit when the line turns. Similarly, the upper extending end face and the upper concave end face between the two butted long edge plates and the lower extending end face and the lower concave end face are in closed fit, so that the phenomena of soil leakage and mud leakage when the line turns are fundamentally avoided.

As the improvement, the short side plate and the long side plate are also provided with upright post holes corresponding to the upright posts in insertion fit, the bottom of the cover plate is provided with short side holes and long side holes corresponding to the short side holes and the long side holes on the bottom plate, and the short side holes and the long side holes at the bottom of the cover plate are correspondingly arranged with the upright post holes at the upper parts of the short side plate and the long side plate up and down and are correspondingly inserted together through the upright posts.

The corresponding stand column hole is arranged on the short edge plate, the upper portion of the long edge plate and the bottom surface of the short edge plate, the fixed assembly connection of the bottom surface of the cover plate, the upper portion of the short edge plate and the upper portion of the long edge plate can be achieved by inserting the stand column into the stand column hole, the cover plate can be buckled on the cable groove, and the three-part relatively fixed connection can be achieved. Therefore, when an earthquake occurs or soil is loosened, the cover plate cannot slide off from the short-edge plate and the long-edge plate, so that the cable tube keeps a tubular structure which is relatively stable, and the effective protection effect is achieved on preventing the cover plate from smashing and breaking the surface of the cable or the optical cable. Because the upright post holes on the upper parts of the short side plate and the long side plate are correspondingly arranged with the upright post holes on the lower parts of the short side plate and the long side plate, the corresponding connection between the upper parts and the lower parts of the short side plate and the long side plate and the corresponding connection between the cover plate and the bottom plate can be realized even if the short side plate and the long side plate are placed in an up-down inverted manner, and the universality of the short side plate and the long side plate and the convenience in field construction are greatly improved.

As an improvement, the middle part of the bottom surface of the cover plate is provided with a positioning groove which is vertically corresponding to the positioning groove on the bottom plate, and the upper part and the lower part of the clapboard are provided with clamping parts which are clamped and supported with the cover plate and the positioning groove on the bottom plate.

After the positioning grooves corresponding to the bottom plate are arranged in the middle of the bottom surface of the cover plate, the positioning grooves on the top surface of the bottom plate and the positioning grooves on the bottom surface of the cover plate are arranged in a one-to-one up-and-down correspondence manner. At the moment, the upper part of the partition board is provided with a clamping part which is clamped and assembled with the positioning groove on the bottom surface of the cover plate, and the lower part of the partition board is also provided with a clamping part which is clamped and assembled with the positioning groove on the bottom plate, so that when the upper end and the lower end of the partition board are respectively clamped and assembled into the positioning grooves on the bottom plate and the cover plate, the partition board not only plays a role of isolating a cavity channel of a 'cable tube' for a three-phase cable, but also plays a supporting role in the middle part of the cover plate, and effectively.

In specific implementation, the included angle between the waist edge and the long edge of the bottom plate is an acute angle of 67.5 degrees, 78.75 degrees, 84.375 degrees or 87.1875 degrees.

For convenience of description, the included angle between the long side and the waist side of the bottom plate is called a waist angle. When the power protection groove line constructed quickly in the hilly area turns, the bottom plates placed subsequently and the last bottom plate extending along the straight line in the power protection groove line constructed quickly in the hilly area are placed in the same direction, and at the moment, the two bottom plates are symmetrically arranged along the waist edges butted with each other. Therefore, the included angle between the two long sides of the two bottom plates is twice the waist angle, namely, two times 67.5 degrees, namely, 135 degrees. For convenience of description, a bottom plate extending along a straight line of a power protection slot line constructed rapidly in a hilly area is referred to as a straight bottom plate, and a bottom plate placed in butt joint with the straight bottom plate in the same direction is referred to as a turning bottom plate. Therefore, it can also be said that the long side of the turning floor is inclined by 135 degrees or 180-. In order to match the extending direction or the laying direction of the power protection groove line for rapid construction in hilly areas, it is generally customary to incline the long side of a turning floor by 45 degrees with respect to the long side of a straight floor. That is, after the power protection groove line rapidly constructed in the hilly area extending along the straight line is butted against the first turning bottom plate, the power protection groove line rapidly constructed in the hilly area turns by 45 degrees. Therefore, when the second turning bottom plate is continuously and unidirectionally placed and butted, the power protection groove line quickly constructed in the hilly area turns to 45 degrees again, so that after the two turning bottom plates are butted, the power protection groove line quickly constructed in the hilly area turns to 45+45=90 degrees in total, and the turning to the vertical direction is also finished. The turning is realized not by on-site cutting like the traditional prefabricated high-voltage cable groove but by smooth transition of the two turning bottom plates and the long side plates and the short side plates on the two turning bottom plates, so that the turning requirement of a power system on laying cables, particularly the turning requirement of optical cables, is better met, and the laying of the cables, the communication quality and the service life are favorably ensured.

When the included angle of the waist edge and the long edge of the bottom plate is an acute angle of 78.75 degrees, when the power protection groove line constructed in the hilly area quickly turns, the bottom plate placed subsequently and the last bottom plate extending along a straight line in the power protection groove line constructed in the hilly area quickly are placed in the same direction, and at the moment, the two bottom plates are symmetrically arranged along the waist edges butted with each other. Thus, the angle between the two long sides of the two base plates is twice the waist angle, i.e. twice 78.75 degrees, i.e. 157.5 degrees. For convenience of description, a bottom plate extending along a straight line of a power protection slot line constructed rapidly in a hilly area is referred to as a straight bottom plate, and a bottom plate placed in butt joint with the straight bottom plate in the same direction is referred to as a turning bottom plate. Thus, it can also be said that the long side of the curved floor is inclined 157.5 degrees or 180-157.5=22.5 degrees with respect to the long side of the straight floor. In order to match the extending direction or the laying direction of the power protection groove line for rapid construction in hilly areas, it is generally customary to incline the long side of a so-called turning floor by 22.5 degrees with respect to the long side of a straight floor. That is, after the power protection groove line for rapid construction in the hilly area extending along the straight line is butted against the first turning bottom plate, the power protection groove line for rapid construction in the hilly area turns by 22.5 degrees. Therefore, when the second turning bottom plate is continuously connected in the same direction, the power protection groove line for rapid construction in the hilly area turns to 22.5 degrees again, so that after the two turning bottom plates are connected, the power protection groove line for rapid construction in the hilly area turns to 22.5+22.5=45 degrees in total. When the third turning bottom plate is continuously placed and butted in the same direction, the power protection groove line quickly constructed in the hilly area turns to 22.5 degrees again, so that after the three turning bottom plates are butted, the power protection groove line quickly constructed in the hilly area turns to 22.5+22.5+22.5=67.5 degrees in total. When the fourth turning bottom plate is continuously placed and butted in the same direction, the power protection groove line quickly constructed in the hilly area turns to 22.5 degrees again, so that after the four turning bottom plates are butted, the power protection groove line quickly constructed in the hilly area turns to 22.5+22.5+22.5+22.5=90 degrees in total, and turning to the vertical direction is also finished. The turning is realized not by on-site cutting like the traditional prefabricated high-voltage cable groove but by smooth transition of four turning bottom plates and long side plates and short side plates on the four turning bottom plates, so that the turning requirement of a power system on laying cables, particularly the turning requirement of optical cables, is met, and the laying of the cables, the communication quality and the service life are guaranteed.

When the contained angle on the waist limit of bottom plate and long limit is acute angle 84.375 degrees, when the electric power protection groove circuit of hilly area quick construction turns round, place the last bottom plate syntropy that extends along the straight line in the bottom plate that will follow-up placing and the electric power protection groove circuit of hilly area quick construction, two bottom plates set up along the waist limit symmetry of both docks this moment. Therefore, the included angle between the two long sides of the two bottom boards is twice the waist angle, i.e. 84.375 degrees, i.e. 168.75 degrees. For convenience of description, a bottom plate extending along a straight line of a power protection slot line constructed rapidly in a hilly area is referred to as a straight bottom plate, and a bottom plate placed in butt joint with the straight bottom plate in the same direction is referred to as a turning bottom plate. Thus, it can also be said that the long side of the curved floor is inclined 168.75 degrees or 180-168.75=11.25 degrees with respect to the long side of the straight floor. In order to match the extending direction or the laying direction of the power protection groove line for rapid construction in hilly areas, it is generally customary to incline the long side of a turning floor by 11.25 degrees with respect to the long side of a straight floor. That is, after the power protection groove line rapidly constructed in the hilly area extending along the straight line is butted against the first turning bottom plate, the power protection groove line rapidly constructed in the hilly area turns by 11.25 degrees. Therefore, when the second turning bottom plate is continuously connected in the same direction, the power protection groove line for rapid construction in the hilly area turns to 11.25 degrees again, so that after the two turning bottom plates are connected, the power protection groove line for rapid construction in the hilly area turns to 11.25+11.25=22.5 degrees in total. Similarly, when the end of the straight line bottom plate is sequentially and continuously placed in the same direction to butt joint with eight turning bottom plates, the inclination angle of the electric power protection groove line for rapid construction in the hilly area relative to the electric power protection groove straight line extension line for rapid construction in the original hilly area is eight times of 11.25, namely 90 degrees, and turning to the vertical direction is also completed. The turning is realized not by on-site cutting like a traditional prefabricated high-voltage cable groove but by smooth transition of an eight-turn bottom plate and a long side plate and a short side plate on the eight-turn bottom plate, so that the turning requirement of a power system on laying cables, particularly the turning requirement of optical cables, is met, and the laying of the cables, the communication quality and the service life are guaranteed.

When the contained angle on the waist limit of bottom plate and long limit is acute angle 87.1875 degrees, when the electric power protection groove circuit of hilly area quick construction turns round, place the last bottom plate syntropy that extends along the straight line in the bottom plate that will follow-up placing and the electric power protection groove circuit of hilly area quick construction, two bottom plates set up along the waist limit symmetry of both docks this moment. Therefore, the included angle between the two long sides of the two bottom boards is twice the waist angle, i.e. 87.1875 degrees, i.e. 174.375 degrees. For convenience of description, a bottom plate extending along a straight line of a power protection slot line constructed rapidly in a hilly area is referred to as a straight bottom plate, and a bottom plate placed in butt joint with the straight bottom plate in the same direction is referred to as a turning bottom plate. Thus, it can also be said that the long side of the corner floor is inclined 174.375 degrees or 180-174.375=5.625 degrees with respect to the long side of the straight floor. In order to match the extending direction or the laying direction of the power protection groove line for rapid construction in hilly areas, it is common practice to incline the long side of the turning floor by 5.625 degrees with respect to the long side of the straight floor. That is, after the power protection groove line for rapid construction in the hilly area extending along the straight line is butted against the first turning floor, the power protection groove line for rapid construction in the hilly area is turned by 5.625 degrees. Therefore, when the second turning floor is continuously connected in the same direction, the power protection groove line for rapid construction in the hilly area turns to 5.625 degrees again, so that after the two turning floors are connected, the power protection groove line for rapid construction in the hilly area turns to 5.625+5.625=11.25 degrees in total. Similarly, when the end of the straight bottom plate is sequentially and continuously placed in the same direction to butt against the sixteen curved bottom plates, the inclination angle of the electric power protection groove line for rapid construction in the hilly area relative to the electric power protection groove straight extension line for rapid construction in the original hilly area is sixteen times of 5.625, namely 90 degrees, and turning to the vertical direction is also completed. The turning is realized not by site cutting like the traditional prefabricated high-voltage cable groove but by smooth transition of sixteen turning bottom plates and long side plates and short side plates on the bottom plates, so that the turning requirement of a power system on laying cables, particularly the turning requirement of optical cables, is met, and the laying of the cables, the communication quality and the service life are guaranteed.

In conclusion, the electric power protection groove adopting the structure and used for rapid construction in the hilly area is reasonable in structure, can be laid along a straight line in an extending mode, can be laid in an arc mode at any time and any place according to turning requirements, is tight in connection and free of gaps, does not need to be filled with gaps, is smooth in transition, simple and rapid in construction and construction, convenient and efficient in disassembly and maintenance, high in cable phase safety, small in storage and occupied space, convenient to transport and not prone to damage, and is particularly suitable for being used for laying cables and optical cables in earthquake-prone areas or soil soft areas.

Detailed Description

As shown in the figure, the power protection groove for rapid construction in the hilly area comprises a bottom plate 1, wherein four sides of the bottom plate 1 are in an isosceles trapezoid shape comprising a short side 2, a long side 3 and two equal-length waist sides 14, two short side holes 6 are arranged on a short side part 4 close to the short side on the bottom plate, two long side holes 7 are arranged on a long side part 5 close to the long side on the bottom plate, and the short side holes and the long side holes are symmetrically arranged relative to a middle line between the short side and the long side; when two bottom plates dock according to the minor face of a bottom plate and the long limit mode of another bottom plate, the butt joint portion both sides correspond the interval in two short limit holes on adjacent short limit hole and the long limit hole and equal with the interval in two short limit holes on the same bottom plate, the downthehole cartridge in short limit hole and the long limit has the stand, be equipped with short sideboard 8 on short limit portion 4, be equipped with long sideboard 9 on long limit portion 5, short sideboard and long limit board bottom are equipped with and correspond cartridge complex stand hole 10 with stand 11, be equipped with two constant head tanks 12 with minor face parallel arrangement on the bottom plate, two constant head tanks are for the intermediate line symmetry setting between minor face and the long limit, the baffle 13 that upwards extends the setting is equipped with to the constant head tank interpolation, short sideboard and long limit board upper portion lock have the apron 21 unanimo.

When needs turn round, that is when needs turn to, need align the adjacent waist of adjacent bottom plate to place two adjacent bottom plates syntropy, also be that either two adjacent bottom plates are all forward to be placed, or two adjacent bottom plates are all reverse to be placed, analogize in proper order. The meaning of equidirectional placing is that the adjacent waist edges of the adjacent bottom plates are aligned, the long edge of one bottom plate is butted with the long edge of the other bottom plate, and the short edge of one bottom plate is butted with the short edge of the other bottom plate. For convenience of description, this placement mode is referred to as a turning placement or turning state. The theoretical basis is that when the automobile seat is in a turning state, any side of two adjacent bottom plates is the side edge of the bottom plate in the same type, namely, when the automobile seat turns leftwards, the left side is short edge connected short edge, the right side is long edge connected long edge, when the automobile seat turns rightwards, the left side is long edge connected long edge, and the right side is short edge connected short edge, so that no matter whether the automobile seat turns leftwards or rightwards, the two adjacent bottom plates are symmetrically arranged by taking the aligned waist edge as a symmetrical line; because the included angle between the waist edge and the long edge of the bottom plate is an acute angle, namely the included angle between the long edges of two adjacent bottom plates is the sum of two acute angles which are necessarily less than 180 degrees, the long edges of the two bottom plates are in different directions, namely are turned or turned. The angle that two bottom plates turned to is exactly the contained angle on two butt joint long sides, and the numerical value of this contained angle equals the twice of the acute angle between waist limit and the long limit and the difference of right angle, for convenient narration, calls this contained angle two-body steering angle. When a third bottom plate is placed in the subsequent same direction, the included angle between the long edge of the third bottom plate and the long edge of the first bottom plate is twice of the two-body steering angle, namely, the power protection groove circuit which is rapidly constructed in the whole hilly area turns to twice of the two-body steering angle; when a fourth bottom plate is placed in the same direction subsequently, the included angle between the long edge of the fourth bottom plate and the long edge of the first bottom plate is three times of the two-body steering angle, namely, the power protection groove circuit which is quickly constructed in the whole hilly area turns to three times of the two-body steering angle, and so on until the required steering angle is reached. In practical application, because the included angle between the waist edge and the long edge is generally set to be an acute angle with a larger value, the numerical value of the steering angle of the two bodies is smaller, namely the steering angle of each subsequent bottom plate is very small, so that the purpose of steering at a large angle (such as 90 degrees) can be achieved by placing the subsequent bottom plates in multiple directions, and the steering of the power protection groove for rapid construction in the hilly area is very smooth and is particularly suitable for underground laying engineering of single-core cables and optical cables.

In this patent, be equipped with end hole 27 at apron length direction both ends, the effect in end hole has two, and an effect is when dismantling the maintenance, and maintainer can stretch the finger or instrument and catch on the apron inner wall in the end hole, then just can very easily take out apron from bottom to top fast, and is very simple. Because the end hole plugs 28 are inserted in the end holes and the adjacent end hole plugs of the adjacent cover plates are connected into a whole through the elastic band 29, the second function of the end holes is to provide locking positions for the end hole plugs, so that the elastic band between the end hole plugs is in an elastic tensioning state, the elastic connection effect on the adjacent cover plates, namely the elastic connection effect on the adjacent cable pipes is realized, particularly when the cable pipe is used in a bent terrain or a region where the soil is easy to loosen and deform, the continuity of the cable pipes can be effectively kept, and the continuity of cables laid inside is relatively protected. The elastic band is fixedly provided with a color band 30 which has three colors of red, blue and yellow, the color band mainly has the function of helping maintenance personnel to visually judge the condition of the internal cable through the color of the color band, the red color band represents that the cable joint is arranged at the position, the blue color band represents that the complete cable passes through, and the yellow color band represents that the cable is damaged or repaired at the position. In practical application, the color band can be provided with more colors, such as black, white and the like, and different identification meanings are given, so that the efficient overhaul of the electric power overhaul personnel is facilitated.

An extending upper extending part 15 is fixedly arranged on the upper part of one end of the short side plate 8, a lower concave part 16 is formed on the lower part of the end of the short side plate and the lower part of the upper extending part, a lower extending part 17 is fixedly arranged on the lower part of the other end of the short side plate, an upper concave part 18 is formed on the upper part of the end of the short side plate and the upper part of the lower extending part, the shape of the upper concave part is matched with that of the upper extending part, the shape of the lower extending part is matched with that of the lower concave part, a positioning column 19 extending downwards is fixedly arranged on the lower end of the upper extending part, and a positioning hole 20 which is inserted and; the one end upper portion of long sideboard sets firmly epitaxial last portion of extending, this end lower part of long sideboard and last extension portion lower part form the concave part down, the other end lower part of long sideboard sets firmly epitaxial lower extension portion, this end upper portion of long sideboard is equipped with and forms the concave part with lower extension portion upper portion, the shape of going up the concave part cooperatees with the shape of last extension portion, the shape of lower extension portion cooperatees with the shape of concave part down, it is equipped with downwardly extending's reference column admittedly to go up extension portion lower extreme, lower extension portion upper end is equipped with the locating hole with the reference column plug-in assembly.

The positioning post 19 has an elastic rubber post that is bent and deformed. After the elasticity that has bending deformation that will reference column design, when the earthquake or geology not hard up warp, between the short sideboard on two adjacent bottom plates, between the long sideboard, or when short sideboard and long sideboard take place the dislocation on the horizontal direction, the reference column can continue the cartridge in the locating hole, but the reference column this moment can take place elastic deformation's distortion, in order to adapt to above-mentioned dislocation, just so guaranteed when earthquake or geology are not hard up, the continuity of this hilly area quick construction's electric power protection groove circuit, avoided traditional high-pressure cable slot or prefabricated high-pressure cable slot breakage when the earthquake takes place or geology not hard up warp, hilly area quick construction's electric power protection groove circuit interrupt scheduling problem, effectively improved the electric power protection groove circuit's of hilly area quick construction connection reliability and the life-span of cable or optical cable in the hilly area.

The positioning column 19 is a conical column with a thicker upper end and a thinner lower end. After the positioning column is arranged to be a conical column with a thicker upper end and a thinner lower end, the positioning hole on the lower extension part is a conical hole with a thicker upper end and a thinner lower end corresponding to the positioning hole. Therefore, when the short side plates are in butt joint, the short side plates are in butt joint with the long side plates, and the long side plates are in butt joint with the long side plates, the thin positioning columns at the lower ends can be easily inserted into the thick positioning holes at the upper ends, and the butt joint is very quick and convenient.

When the short side plate 8 and the long side plate 9 are inserted on the corresponding side of the bottom plate through the upright post 11, the axial leads of the positioning column 19 and the positioning hole 20 are flush with the corresponding end surface of the bottom plate. When short sideboard, long sideboard corresponds the cartridge through the stand and corresponds the avris at the bottom plate, thereby when assembling into required "cable duct", set up the reference column at short sideboard and long sideboard both ends and the axial lead of locating hole just in time with bottom plate terminal surface parallel and level, also be exactly with waist limit parallel and level, can guarantee two sets of "cable ducts" no matter place the butt joint according to the forward or when placing the butt joint according to the reverse, can both guarantee the short sideboard on two bottom plates, long sideboard passes through the reference column in butt joint portion, also dock directly over the waist limit that also is in the butt joint. That is to say, with reference column, locating hole axial lead and waist limit parallel and level, can make between adjacent or butt joint's short side board and short side board, between short side board and the long side board, have "articulated" function between long side board and the long side board, make two adjacent or butt joint "cable groove" have "articulated" function promptly. The hinging function can ensure that two adjacent bottom plates are smoothly connected together through the butted short side plates and long side plates no matter the cable slot extends linearly or turns, and ensures the continuity, smoothness and integrity of the electric power protection slot line constructed quickly in the whole hilly area.

The upright post 11 is a symmetrical conical column with a thicker middle part and thinner two ends. After the upright column is set into a symmetrical conical column with a thicker middle part and thinner two ends, the long side hole and the short side hole on the bottom plate are conical holes with thicker upper ports and thinner inner ends corresponding to the long side hole and the short side hole, and the upright column holes at the lower ends of the long side plate and the short side plate are conical holes with thicker lower ports and thinner inner holes matched with the upper part of the upright column. Therefore, when the lower parts of the stand columns are inserted into the long side holes and the short side holes of the bottom plate, the stand columns with thin lower ends can be easily inserted into the long side holes and the short side holes with thick upper ends, and the insertion is very quick and convenient. Similarly, when the long side plate and the short side plate are correspondingly assembled to the long side part and the short side part of the bottom plate, the upright post with the thin upper end can be easily inserted into the upright post hole with the thick lower end, the overall assembly speed is improved, and the construction efficiency is improved.

The upper extension end face 22 of the upper extension part is an outer convex arc surface taking the axis of the positioning column as the axis, the lower concave end face 23 of the lower concave part is an inner concave arc surface taking the axis of the positioning column as the axis, the lower extension end face 24 of the lower extension part is an outer convex arc surface taking the axis of the positioning hole as the axis, the upper concave end face 25 of the upper concave part is an inner concave arc surface taking the axis of the positioning hole as the axis, the upper extension end face is in sliding fit with the upper concave end face, and the lower extension end face is in sliding fit with the lower concave end face. For convenience of description, a bottom plate extending along a straight line of a power protection slot line constructed rapidly in a hilly area is referred to as a straight bottom plate, and a bottom plate placed in butt joint with the straight bottom plate in the same direction is referred to as a turning bottom plate. Because the last end of extending of portion is the evagination arc surface with reference column axial lead as the axial lead, the last concave end of going up the concave part is the indent arc surface with the locating hole axial lead as the axial lead, and extend end and last concave end sliding fit, consequently, when two bottom plates equidirectionally place the butt joint, namely a bottom plate is the straight line bottom plate, when a bottom plate is the bottom plate that turns round, the contained angle between the short sideboard and the short sideboard of homonymy butt joint on two bottom plates is less than 180 degrees, that is to say that both are not aligned, under the articulated cooperation of the reference column that two short sideboard correspond and locating hole like this, can form an contained angle, this contained angle is aforementioned two body steering angle promptly. Because the corresponding upward extending end face and the upward concave end face of the two butt-joint short side plates are in sliding fit around the axial lead of the positioning shaft, even if the two short side plates are in cross fit or hinged fit at a two-body steering angle, the butt-joint parts of the two short side plates, namely the upward extending end face and the upward concave end face, are still in airtight fit, the tightness of the electric power protection groove line which is quickly constructed in the whole hilly area when turning is ensured, the defect that gaps need to be filled when traditional prefabricated high-voltage cable grooves are laid is avoided, and the phenomena of soil leakage and mud leakage are fundamentally avoided. Similarly, the lower end face and the concave end face between the two butt short side plates are in close fit when the line turns. Similarly, the upper extending end face and the upper concave end face between the two butted long edge plates and the lower extending end face and the lower concave end face are in closed fit, so that the phenomena of soil leakage and mud leakage when the line turns are fundamentally avoided.

The short side plate and the long side plate are also provided with upright post holes 10 corresponding to the upright posts in the inserting fit, the bottom of the cover plate is provided with short side holes and long side holes corresponding to the short side holes and the long side holes on the bottom plate, and the short side holes and the long side holes at the bottom of the cover plate are correspondingly arranged up and down with the upright post holes at the upper parts of the short side plate and the long side plate and are correspondingly inserted together through the upright posts. The corresponding stand column hole is arranged on the short edge plate, the upper portion of the long edge plate and the bottom surface of the short edge plate, the fixed assembly connection of the bottom surface of the cover plate, the upper portion of the short edge plate and the upper portion of the long edge plate can be achieved by inserting the stand column into the stand column hole, the cover plate can be buckled on the cable groove, and the three-part relatively fixed connection can be achieved. Therefore, when an earthquake occurs or soil is loosened, the cover plate cannot slide off from the short-edge plate and the long-edge plate, so that the cable tube keeps a tubular structure which is relatively stable, and the effective protection effect is achieved on preventing the cover plate from smashing and breaking the surface of the cable or the optical cable. Because the upright post holes on the upper parts of the short side plate and the long side plate are correspondingly arranged with the upright post holes on the lower parts of the short side plate and the long side plate, the corresponding connection between the upper parts and the lower parts of the short side plate and the long side plate and the corresponding connection between the cover plate and the bottom plate can be realized even if the short side plate and the long side plate are placed in an up-down inverted manner, and the universality of the short side plate and the long side plate and the convenience in field construction are greatly improved.

The middle part of the bottom surface of the cover plate is provided with a positioning groove which is vertically corresponding to the positioning groove on the bottom plate, and the upper part and the lower part of the clapboard are provided with clamping parts 26 which are clamped and supported with the positioning grooves on the cover plate and the bottom plate. After the positioning grooves corresponding to the bottom plate are arranged in the middle of the bottom surface of the cover plate, the positioning grooves on the top surface of the bottom plate and the positioning grooves on the bottom surface of the cover plate are arranged in a one-to-one up-and-down correspondence manner. At the moment, the upper part of the partition board is provided with a clamping part which is clamped and assembled with the positioning groove on the bottom surface of the cover plate, and the lower part of the partition board is also provided with a clamping part which is clamped and assembled with the positioning groove on the bottom plate, so that when the upper end and the lower end of the partition board are respectively clamped and assembled into the positioning grooves on the bottom plate and the cover plate, the partition board not only plays a role of isolating a cavity channel of a 'cable tube' for a three-phase cable, but also plays a supporting role in the middle part of the cover plate, and effectively. In this embodiment, the cross section of the positioning groove 12 on the bottom plate 1 is a wedge-shaped groove with a wide upper end and a narrow lower end, and the clamping portion matched with the wedge-shaped groove is also a wedge-shaped strip with a narrow lower end and a wide upper end, so as to facilitate quick clamping. Similarly, the cross section of the positioning groove 12 on the cover plate 21 is a wedge-shaped groove with a narrow upper end and a wide lower end, and the clamping part matched with the wedge-shaped groove is also a wedge-shaped strip with a narrow upper end and a wide lower end.

As shown in the figure, the included angle between the waist edge and the long edge of the bottom plate is an acute angle of 67.5 degrees.

In this embodiment, the included angle between the waist edge and the long edge of the bottom plate is an acute angle of 78.75 degrees.

When the power protection groove line constructed quickly in the hilly area turns, the bottom plates placed subsequently and the last bottom plate extending along the straight line in the power protection groove line constructed quickly in the hilly area are placed in the same direction, and at the moment, the two bottom plates are symmetrically arranged along the waist edges butted with each other. Thus, the angle between the two long sides of the two base plates is twice the waist angle, i.e. twice 78.75 degrees, i.e. 157.5 degrees. For convenience of description, a bottom plate extending along a straight line of a power protection slot line constructed rapidly in a hilly area is referred to as a straight bottom plate, and a bottom plate placed in butt joint with the straight bottom plate in the same direction is referred to as a turning bottom plate. Thus, it can also be said that the long side of the curved floor is inclined 157.5 degrees or 180-157.5=22.5 degrees with respect to the long side of the straight floor. In order to match the extending direction or the laying direction of the power protection groove line for rapid construction in hilly areas, it is generally customary to incline the long side of a so-called turning floor by 22.5 degrees with respect to the long side of a straight floor. That is, after the power protection groove line for rapid construction in the hilly area extending along the straight line is butted against the first turning bottom plate, the power protection groove line for rapid construction in the hilly area turns by 22.5 degrees. Therefore, when the second turning bottom plate is continuously connected in the same direction, the power protection groove line for rapid construction in the hilly area turns to 22.5 degrees again, so that after the two turning bottom plates are connected, the power protection groove line for rapid construction in the hilly area turns to 22.5+22.5=45 degrees in total. When the third turning bottom plate is continuously placed and butted in the same direction, the power protection groove line quickly constructed in the hilly area turns to 22.5 degrees again, so that after the three turning bottom plates are butted, the power protection groove line quickly constructed in the hilly area turns to 22.5+22.5+22.5=67.5 degrees in total. When the fourth turning bottom plate is continuously placed and butted in the same direction, the power protection groove line quickly constructed in the hilly area turns to 22.5 degrees again, so that after the four turning bottom plates are butted, the power protection groove line quickly constructed in the hilly area turns to 22.5+22.5+22.5+22.5=90 degrees in total, and turning to the vertical direction is also finished. The turning is realized not by on-site cutting like the traditional prefabricated high-voltage cable groove but by smooth transition of four turning bottom plates and long side plates and short side plates on the four turning bottom plates, so that the turning requirement of a power system on laying cables, particularly the turning requirement of optical cables, is met, and the laying of the cables, the communication quality and the service life are guaranteed.

In another preferred embodiment, the included angle between the waist edge and the long edge of the bottom board is an acute angle 84.375 degrees.

When the power protection groove line constructed quickly in the hilly area turns, the bottom plates placed subsequently and the last bottom plate extending along the straight line in the power protection groove line constructed quickly in the hilly area are placed in the same direction, and at the moment, the two bottom plates are symmetrically arranged along the waist edges butted with each other. Therefore, the included angle between the two long sides of the two bottom boards is twice the waist angle, i.e. 84.375 degrees, i.e. 168.75 degrees. For convenience of description, a bottom plate extending along a straight line of a power protection slot line constructed rapidly in a hilly area is referred to as a straight bottom plate, and a bottom plate placed in butt joint with the straight bottom plate in the same direction is referred to as a turning bottom plate. Thus, it can also be said that the long side of the curved floor is inclined 168.75 degrees or 180-168.75=11.25 degrees with respect to the long side of the straight floor. In order to match the extending direction or the laying direction of the power protection groove line for rapid construction in hilly areas, it is generally customary to incline the long side of a turning floor by 11.25 degrees with respect to the long side of a straight floor. That is, after the power protection groove line rapidly constructed in the hilly area extending along the straight line is butted against the first turning bottom plate, the power protection groove line rapidly constructed in the hilly area turns by 11.25 degrees. Therefore, when the second turning bottom plate is continuously connected in the same direction, the power protection groove line for rapid construction in the hilly area turns to 11.25 degrees again, so that after the two turning bottom plates are connected, the power protection groove line for rapid construction in the hilly area turns to 11.25+11.25=22.5 degrees in total. Similarly, when the end of the straight line bottom plate is sequentially and continuously placed in the same direction to butt joint with eight turning bottom plates, the inclination angle of the electric power protection groove line for rapid construction in the hilly area relative to the electric power protection groove straight line extension line for rapid construction in the original hilly area is eight times of 11.25, namely 90 degrees, and turning to the vertical direction is also completed. The turning is realized not by on-site cutting like a traditional prefabricated high-voltage cable groove but by smooth transition of an eight-turn bottom plate and a long side plate and a short side plate on the eight-turn bottom plate, so that the turning requirement of a power system on laying cables, particularly the turning requirement of optical cables, is met, and the laying of the cables, the communication quality and the service life are guaranteed.

In another preferred embodiment, the included angle between the waist edge and the long edge of the bottom board is an acute angle 87.1875 degrees.

When the power protection groove line constructed quickly in the hilly area turns, the bottom plates placed subsequently and the last bottom plate extending along the straight line in the power protection groove line constructed quickly in the hilly area are placed in the same direction, and at the moment, the two bottom plates are symmetrically arranged along the waist edges butted with each other. Therefore, the included angle between the two long sides of the two bottom boards is twice the waist angle, i.e. 87.1875 degrees, i.e. 174.375 degrees. For convenience of description, a bottom plate extending along a straight line of a power protection slot line constructed rapidly in a hilly area is referred to as a straight bottom plate, and a bottom plate placed in butt joint with the straight bottom plate in the same direction is referred to as a turning bottom plate. Thus, it can also be said that the long side of the corner floor is inclined 174.375 degrees or 180-174.375=5.625 degrees with respect to the long side of the straight floor. In order to match the extending direction or the laying direction of the power protection groove line for rapid construction in hilly areas, it is common practice to incline the long side of the turning floor by 5.625 degrees with respect to the long side of the straight floor. That is, after the power protection groove line for rapid construction in the hilly area extending along the straight line is butted against the first turning floor, the power protection groove line for rapid construction in the hilly area is turned by 5.625 degrees. Therefore, when the second turning floor is continuously connected in the same direction, the power protection groove line for rapid construction in the hilly area turns to 5.625 degrees again, so that after the two turning floors are connected, the power protection groove line for rapid construction in the hilly area turns to 5.625+5.625=11.25 degrees in total. Similarly, when the end of the straight bottom plate is sequentially and continuously placed in the same direction to butt against the sixteen curved bottom plates, the inclination angle of the electric power protection groove line for rapid construction in the hilly area relative to the electric power protection groove straight extension line for rapid construction in the original hilly area is sixteen times of 5.625, namely 90 degrees, and turning to the vertical direction is also completed. The turning is realized not by site cutting like the traditional prefabricated high-voltage cable groove but by smooth transition of sixteen turning bottom plates and long side plates and short side plates on the bottom plates, so that the turning requirement of a power system on laying cables, particularly the turning requirement of optical cables, is met, and the laying of the cables, the communication quality and the service life are guaranteed.
