Background technology
Along with the progressively raising that city power supply quality requires, current state inner city high voltage supply mode, substantially completes and to be powered the conversion of powering to underground high-voltage by high voltage overhead lines.Underground high-voltage is powered and is mainly comprised underground piping high voltage supply and underground trench high-pressure and to power two kinds of forms.Wherein, underground trench high-pressure is powered needs at the high-tension cable groove of provided underground splendid attire high voltage cable.
Industry construction regulation has been made in the laying of electric power system to high voltage cable groove, is specially: 1. the place such as cable climbing pole tower rationally must add great burying according to site specific.To meet turning of cable radius requirement; 2. path, subsurface 300mm place buries cable trace colored belt underground, width 1300mm; 3. cable laying radius of turn should not be less than 20 times of the outside diameter of cable; If 4. need laying optical cable, then the radius of turn of optical cable is not less than 3m; 5, unaccomplished matter is by existing associated construction regulation enforcement.
Traditional high voltage cable groove, employing clay common brick, cement mortar scene are built by laying bricks or stones and are formed.The shortcoming of conventional high-tension cable trench is, main material due to masonry is solid clay common brick, and solid clay common brick occupies cultivated land in a large number because of its production, consume the energy, it is a kind of nondegradable resource consumption finished product, progressively even prohibitted the use by each large, medium and small city limitation, and cable trough is built at scene by laying bricks or stones, various raw material not manageability, engineering construction efficiency is low, the construction period is long, expense is large.The advantage of conventional high-tension cable trench is, groove can be made the shape and camber that need arbitrarily, have the advantage meeting construction requirement completely.
There is a kind of prefabricated high voltage cable groove in the market, this high voltage cable groove mainly comprises the concordant integral type cell body in two ends, this cell body mainly comprises a base plate, the base plate left and right sides is installed with the side plate upwards extended respectively, form oral area U-lag upwards thus, structure is very simple.Only each cell body need be mated formation end to end in the trench dug in use, and real with cover plate lid, operate very simple.But the weak point of this high voltage cable groove is, 1, be only suitable for laying straight line cable groove, when cable groove is turned, generally right-angled bend can only be carried out, if meet the radius of turn requirement of power industry construction regulation, scene carried out to prefabricated high voltage cable groove and cuts shaping, to make each prefabricated high voltage cable groove docking of corner concordant, on-the-spot difficulty of processing is large, waste time and energy; Gap is left to meet requirement of turning round between each prefabricated high voltage cable groove of corner, but must occur that gap location leaks after using like this, leak native phenomenon, finally cause filling silt in cable groove, not only do not meet construction requirement, make troubles also to maintaining cables, transformation in the future; 2, due to the U-shaped profile of prefabricated high voltage cable groove, therefore take up room comparatively large, extremely inconvenient transporting, when depositing, and also this structure impact resistance is little, easy stressed breakage; 3, do not arrange escapement in prefabricated high voltage cable groove, three single-core cables lay in same groove, can contact between phase and phase by good fortune cable, easily cause cable fault; 4, when groove circuit turns round, the joining place of each prefabricated high voltage cable groove can form the gap differed in size, need extra scene to carry out joint filling construction, otherwise by occurring that earth flows into leakage soil, leakage mud phenomenon in groove cavity, have a strong impact on the use safety of groove inner cable or optical cable.
Existing partial design unit in charge of construction also uses in-situ precast concrete pit, because the cruelty in work progress during unloading uses, kerve and cover plate can be made to cause reinforcing steel bars exposed because there is concrete layer destruction, when cover plate reinforcing bar contacts with concrete pit below, closed magnetic loop certainly will be formed to single-core cable, cause single-core cable to cause damage because of eddy current.

The technical problems to be solved in the utility model provides a kind of rational in infrastructure for above-mentioned deficiency, linearly can extend laying, can need to do arc whenever and wherever possible according to turning again to lay, be connected tight, gapless, without the need to joint filling, transition is round and smooth, construction is simple and quick, demolition and maintenance convenience and high-efficiency, the alternate fail safe of cable is high, and deposit take up room little, the earthquake region of convenient transportation, not cracky and the soil is porous cable trough that area uses.
For solving the problems of the technologies described above, this earthquake region and the soil is porous that the design feature of cable trough that area uses is: comprise base plate, base plate four limit is comprise parallel minor face and long limit, and the isosceles trapezoid on two isometric waist limits, short leg near minor face on base plate is provided with two minor face holes, on base plate near the long leg on long limit be provided with two long lateral opening, minor face hole and to be longly lateral openingly symmetrical arranged relative to the mid line between minor face and long limit, when two base plates dock with the long limit mode of another base plate according to the minor face of a base plate, corresponding adjacent minor face hole, both sides, docking section and long lateral opening between spacing equal with the spacing in two minor face holes on same base plate, column is fitted with in minor face hole is lateral opening with length, short leg is provided with minor face plate, long leg is provided with long side plate, the leghole that plug-in mounting corresponding to column coordinates is provided with bottom minor face plate and long side plate, base plate is provided with two location notchs be arranged in parallel with minor face, two location notchs are symmetrical arranged relative to the mid line between minor face and long limit, upwards extended dividing plate is fitted with in location notch, minor face plate fastens with long side plate top the cover plate consistent with base plate configuration, the sidewall that cover plate is corresponding with minor face plate and long side plate is skew wall, the upper edge of skew wall extends outside minor face plate and long side plate along cover plate plate, the lower edge of skew wall is alignd with minor face plate and long side plate and is arranged.
In the utility model, earthquake region and the soil is porous area use cable trough form primarily of base plate, minor face plate, long side plate, dividing plate, column and cover plate.Wherein, base plate is this earthquake region and the soil is porous the core component of cable trough that area uses, its Main Function, not still for miscellaneous part provides support, be the more important thing is whole earthquake region and the soil is porous that the laying direction of cable trough circuit that area uses serves guiding or orientation.This earthquake region and the soil is porous area use cable trough in, base plate is to whole piece earthquake region and the soil is porous the guiding of cable trough circuit that area uses or orientation, be not rely on workman's Site Design to complete, but rely on the architectural feature of base plate self to realize.This earthquake region and the soil is porous area use cable trough in, base plate is isosceles trapezoidal structure, its four limits are respectively minor face, long limit and two waist limits, wherein minor face shorter than long limit and both be arranged in parallel, the mid point line on two waist edge minor faces and long limit is symmetrical arranged.
For convenience of describing, when being layered in groove by base plate, at the pose pattern on the right side, minor face is called that forward or forward are placed on left long limit, to be called on long limit oppositely or oppositely to place at left minor face at the pose pattern on the right side.When need by earthquake region and the soil is porous the route of cable trough that area uses linearly extends time, need the waist limit of two base plates align, and by two adjacent reverse placements of base plate, namely a forward places an oppositely placement, or one is oppositely placed a forward placement, the like.During reverse placement, the adjacent waist limit alignment of two adjacent bottom plates, and the minor face of a base plate docks with the long limit of another base plate, the long limit of a base plate is docked with the minor face of another base plate.For convenience of describing, this kind of disposing way being become straight line and puts or linear state.Its theoretical foundation is, when linear state, that minor face connects long limit on the left of two adjacent bottom plates, then that long limit connects minor face on right side, again because the minor face of each base plate is isometric, long limit is also isometric, and therefore during linear state, the minor face of each base plate and long limit are all in the same way, linearly extend after ensure that each base plate paving.Also can say so, in the isosceles trapezoidal structure of base plate, the angle on long limit and waist limit is acute angle, and the angle on minor face and waist limit is obtuse angle, this acute angle and obtuse angle and be just in time 180 degree.And when linear state, the adjacent waist limit of two base plates is aligned together, and the long limit of two base plates and minor face are docking together, that is an obtuse angle of two base plates and an acute angle are docking together, obviously both sums are also 180 degree, that is the angle between the minor face of two base plates docking and long limit is 180, namely a straight straight line.
When needs turn round, namely when needs turn to, need the adjacent waist limit alignment of adjacent bottom plates, and two adjacent bottom plates are placed in the same way, namely or two adjacent bottom plates are all that forward is placed, or two adjacent bottom plates are all reverse placements, the like.The meaning of placing in the same way be exactly the adjacent waist limit alignment of adjacent bottom plates, and the long limit of a base plate is docked with the long limit of another base plate, the minor face of a base plate docks with the minor face of another base plate.For convenience of describing, being called by this kind of disposing way turns round puts or turns round state.Its theoretical foundation is, when turning round state, the either side of two adjacent bottom plates is all the base plate side of identical type, namely, when turning left, left side is that minor face connects minor face, and right side is that long limit connects long limit, when turning right, left side is spreading limit, long limit, and right side is that minor face connects minor face, like this, no matter turn left or turn right, two adjacent bottom plates are exactly be symmetrical arranged for line of symmetry with waist limit of aliging; Again because the angle between the waist limit of base plate and long limit is acute angle, the angle between the long limit of that is two adjacent bottom plates is two acute angle sums, and it must be less than 180 degree, therefore the long limit of two base plates is not in the same way, that is to say turn round or turn to.The angle that two base plates turn to or angle of inclination are exactly the difference of two angles to spreading limit and 180 degree, its numerical value also equals the twice of the difference at acute angle between waist limit and long limit and right angle, for convenience of describing, acute angle between waist limit and long limit is called haunch, 180 and the difference of the twice value of this haunch are called two body steering angle or steering angles.When follow-up placement in the same way the 3rd base plate, the angle on the 3rd the long limit of base plate and first long limit of base plate is exactly two body steering angles of twice, that is, whole piece earthquake region and the soil is porous that cable trough circuit that area uses has turned to the angle of two body steering angles of twice; When follow-up placement in the same way the 4th base plate, the angle on the 4th the long limit of base plate and first long limit of base plate is exactly the two body steering angles of three times, that is whole piece earthquake region and the soil is porous that cable trough circuit that area uses has turned to the angle of the two body steering angles of three times, by that analogy, till meeting the requirements of steering angle.In actual applications, because the angle between waist limit and long limit is typically provided to the larger acute angle of numerical value, so make the numerical value of two body steering angles less, that is the steering angle of each follow-up base plate is very little, the object that wide-angle (as 90 degree) turns to so just can be reached by the mode of how placing follow-up base plate in the same way, therefore, this earthquake region and the soil is porous area use turning to of cable trough be very round and smooth, be particularly suitable for single-core cable, optical cable provided underground engineering use.

After reference column being arranged to the thinner circular cone post in thicker lower end, upper end, the location hole on lower extending part is also just in the conical bore that thicker lower end, upper end corresponding is with it thinner.Like this, dock between minor face plate, minor face plate docks with long side plate, and when long side plate docks with long side plate, the thinner reference column in lower end just can insert in the thicker location hole in upper end easily, docks very quick and easy.
As improvement, when minor face plate and long side plate are inserted into base plate correspondence avris by column, reference column is concordant with corresponding base plate end face with the axial line of location hole.
When minor face plate, long side plate are inserted into the corresponding avris of base plate by column correspondence, thus when being assembled into required " cable trough ", minor face plate and the long reference column at side plate two ends and the axial line of location hole are arranged just in time concordant with base plate end face, namely concordant with waist limit, when can ensure no matter two groups " cable trough " place docking according to forward or dock according to reverse placement, the minor face plate on two base plates, long side plate can be ensured by reference column in docking section, namely dock directly over the waist limit of docking.That is, reference column, location hole axial line is concordant with waist limit, can make between minor face plate that is adjacent or that connect and minor face plate, between minor face plate and long side plate, there is between long side plate and long side plate " hinged " function, namely make two adjacent or that connect " cable trough " there is " hinged " function.And described " hinged " function, no matter when being exactly the extension of " cable trough " straight line, or when turning round, can ensure two adjacent bottom plates by the minor face plate of docking, long side plate is smooth and easy links together, and ensure that whole piece earthquake region and continuity, smoothness, the integraty of the soil is porous cable trough circuit that area uses.
As improvement, described column is the thinner symmetrical circular cone posts in middle thicker two ends.
After column being arranged to the thinner symmetrical circular cone post in middle thicker two ends, length on base plate is lateral opening is also just the upper port coniform hole that comparatively slightly the inner is thinner corresponding with it with minor face hole, and the leghole of long side plate and minor face plate lower end is also in the coniform hole that the thicker endoporus of lower port matched with column top is thinner.Like this, when column bottom being inserted in the lateral opening and minor face hole of the length of base plate, it is lateral opening with in minor face hole that the thinner column in lower end just can insert the thicker length in upper end easily, and plug-in mounting is very quick and easy.Same, when long side plate and minor face plate correspondence are assembled to long leg and the short leg of base plate, the thinner column in upper end just can be inserted in the thicker leghole in lower end easily, improves overall assembling speed, contributes to raising efficiency of construction.
As improvement, on prolong portion on prolong end face in the outer convex arc surface that is axial line with reference column axial line, the recessed end face of lower concave part is for concaved circular cambered surface in axial line with reference column axial line, the downward end face of lower extending part is in the outer convex arc surface being axial line with location hole axial line, the fovea superior end face of upper recess is for concaved circular cambered surface in axial line with location hole axial line, on prolong end face and fovea superior end face is slidably matched, downward end face and recessed end face are slidably matched.
For convenience of describing, by earthquake region and the soil is porous that the base plate that linearly extends of cable trough circuit that area uses is called straight line base plate, be called placing with it base plate docked in the same way the base plate that turns round.Because on prolong portion on prolong end face in the outer convex arc surface that is axial line with reference column axial line, the fovea superior end face of upper recess is for concaved circular cambered surface in axial line with location hole axial line, and on prolong end face and fovea superior end face is slidably matched, therefore, when two base plates place docking in the same way, namely a base plate is straight line base plate, base plate for turn round base plate time, angle between the minor face plate of homonymy docking on two base plates and minor face plate is less than 180 degree, that is both are not alignment, like this under the hinged cooperation of reference column corresponding to two minor face plates and location hole, meeting shape in an angle, namely this angle is aforesaid two body steering angles.Due to two docking minor face plates corresponding on prolong end face and fovea superior end face is slidably matched around locating shaft axial line, even if therefore aforementioned two minor face plates coordinate or hinged cooperation with two body steering angles intersections, but the docking section of two minor face plates, prolong namely between end face and fovea superior end face is still close fit, ensure that when turning round whole piece earthquake region and the seal of the soil is porous cable trough circuit that area uses, avoiding traditional prefabricated high voltage cable groove needs pay the seam drawback when laying, fundamentally avoiding Lou soil, leakage mud phenomenon.Same, be also close fit when circuit turns round between the downward end face between two docking minor face plates and recessed end face.In like manner, between the long side plates of two docking, to prolong between end face and fovea superior end face, between downward end face and recessed end face be also close fit, fundamentally avoid circuit turn round hourglass soil, leak mud phenomenon.
As improvement, minor face plate and long side plate top are also provided with the leghole that plug-in mounting corresponding to column coordinates, be provided with bottom cover plate and the minor face hole on base plate, long lateral opening corresponding minor face hole and long lateral opening, and minor face hole bottom cover plate and long lateral opening with minor face plate with the leghole on long side plate top is corresponding up and down arranges and to pass through column corresponding plug-in.
On minor face plate and long side plate top and minor face plate bottom surface, corresponding leghole is set, can by column being inserted to the mode in leghole, realize the fixed assembly connection on cover plate bottom surface and minor face plate top and long side plate top, cover plate so not only can be realized to fasten in " cable trough ", the relatively-stationary connection of three can also be realized.Therefore, when running into earthquake or soil property loosens, cover plate also will, from landing minor face plate and long side plate, make " cable tube " keep a metastable tubulose of structure, breaks cable or optical cable epidermis serves available protecting effect to preventing cover plate.Because the leghole on minor face plate and long side plate top and the leghole of both bottoms are corresponding settings, therefore, even if minor face plate and long side plate turned upside down are put, also can realize minor face plate to be connected with cover plate and the corresponding of base plate respectively with the top and the bottom of long side plate, substantially increase the versatility of minor face plate and long side plate, and convenience when constructing at the scene.
As improvement, in the middle part of cover plate bottom surface, be provided with the location notch up and down corresponding with the location notch on base plate, dividing plate upper and lower be provided with clamp with location notch on cover plate and base plate, support coordinate clamp portion.
Arrange the location notch corresponding with base plate in the middle part of cover plate bottom surface after, the location notch of plate top surface will correspondingly up and down one by one be arranged with the location notch on cover plate bottom surface.And now, due to dividing plate top be provided with cover plate bottom surface location notch snap fit clamp portion, the lower partition be also provided with base plate location notch snap fit clamp portion, therefore, when the upper and lower two ends of dividing plate clamp respectively in the location notch on base plate and cover plate, dividing plate not only serves the effect into threephase cable isolation " cable tube " cavity, also serves supporting role in the middle part of cover plate, effectively ensure that the bearing capacity of cover plate.
In the specific implementation, the waist limit of described base plate and the angle on long limit are acute angle 67.5 degree or 78.75 degree or 84.375 degree or 87.1875 degree.
For convenience of describing, the angle between the long limit of base plate and waist limit is called haunch.Earthquake region and the soil is porous area use cable trough circuit turn round time, placed in the same way by last base plate linearly extended in the base plate of follow-up placement and earthquake region and the soil is porous cable trough circuit that area uses, waist limits that now two base plates dock along both are symmetrical arranged.Therefore, the angle between two long limits of two base plates is exactly the haunch of twice, i.e. the twice of 67.5 degree, is also 135 degree.For convenience of describing, by earthquake region and the soil is porous that the base plate that linearly extends of cable trough circuit that area uses is called straight line base plate, be called placing with it base plate docked in the same way the base plate that turns round.Therefore, alternatively, the turn round long limit of base plate to have tilted 135 degree or 180-135=45 degree relative to the long limit of straight line base plate.In order to earthquake region and the soil is porous the bearing of trend of cable trough circuit that area uses or to lay direction consistent, general custom is called that the long limit of the base plate that turns round has tilted 45 degree relative to the long limit of straight line base plate.That is, the earthquake region linearly extended and the soil is porous area use cable trough circuit dock first base plate that turns round after, earthquake region and the soil is porous area use cable trough circuit turned to 45 degree.Therefore, when continue in the same way place docking second turn round base plate time, earthquake region and the soil is porous area use cable trough circuit will again turn to 45 degree, like this, after docking two base plates that turn round, earthquake region and the soil is porous area use cable trough circuit altogether turn to 45+45=90 degree, also just complete and turn round to vertical direction.This realization of turning round, be not realize right-angle turning by on-site cutting as traditional prefabricated high-tension cable groove, but by two turn round base plate and on long side plate, minor face plate rounding off realize, so more meet electric power system to the requirement of turning round of laying cable, the particularly requirement of turning round of optical cable, contributes to ensureing the laying of cable and communication quality and life-span.

In the utility model, earthquake region and the soil is porous area use cable trough form primarily of base plate, minor face plate, long side plate, dividing plate, column and cover plate.Wherein, base plate is this earthquake region and the soil is porous the core component of cable trough that area uses, its Main Function, not still for miscellaneous part provides support, be the more important thing is whole earthquake region and the soil is porous that the laying direction of cable trough circuit that area uses serves guiding or orientation.This earthquake region and the soil is porous area use cable trough in, base plate is to whole piece earthquake region and the soil is porous the guiding of cable trough circuit that area uses or orientation, be not rely on workman's Site Design to complete, but rely on the architectural feature of base plate self to realize.This earthquake region and the soil is porous area use cable trough in, base plate is isosceles trapezoidal structure, its four limits are respectively minor face, long limit and two waist limits, wherein minor face shorter than long limit and both be arranged in parallel, the mid point line on two waist edge minor faces and long limit is symmetrical arranged.
For convenience of describing, when being layered in groove by base plate, at the pose pattern on the right side, minor face is called that forward or forward are placed on left long limit, to be called on long limit oppositely or oppositely to place at left minor face at the pose pattern on the right side.When need by earthquake region and the soil is porous the route of cable trough that area uses linearly extends time, need the waist limit of two base plates align, and by two adjacent reverse placements of base plate, namely a forward places an oppositely placement, or one is oppositely placed a forward placement, the like.During reverse placement, the adjacent waist limit alignment of two adjacent bottom plates, and the minor face of a base plate docks with the long limit of another base plate, the long limit of a base plate is docked with the minor face of another base plate.For convenience of describing, this kind of disposing way being become straight line and puts or linear state.Its theoretical foundation is, when linear state, that minor face connects long limit on the left of two adjacent bottom plates, then that long limit connects minor face on right side, again because the minor face of each base plate is isometric, long limit is also isometric, and therefore during linear state, the minor face of each base plate and long limit are all in the same way, linearly extend after ensure that each base plate paving.Also can say so, in the isosceles trapezoidal structure of base plate, the angle on long limit and waist limit is acute angle, and the angle on minor face and waist limit is obtuse angle, this acute angle and obtuse angle and be just in time 180 degree.And when linear state, the adjacent waist limit of two base plates is aligned together, and the long limit of two base plates and minor face are docking together, that is an obtuse angle of two base plates and an acute angle are docking together, obviously both sums are also 180 degree, that is the angle between the minor face of two base plates docking and long limit is 180, namely a straight straight line.
When needs turn round, namely when needs turn to, need the adjacent waist limit alignment of adjacent bottom plates, and two adjacent bottom plates are placed in the same way, namely or two adjacent bottom plates are all that forward is placed, or two adjacent bottom plates are all reverse placements, the like.The meaning of placing in the same way be exactly the adjacent waist limit alignment of adjacent bottom plates, and the long limit of a base plate is docked with the long limit of another base plate, the minor face of a base plate docks with the minor face of another base plate.For convenience of describing, being called by this kind of disposing way turns round puts or turns round state.Its theoretical foundation is, when turning round state, the either side of two adjacent bottom plates is all the base plate side of identical type, namely, when turning left, left side is that minor face connects minor face, and right side is that long limit connects long limit, when turning right, left side is spreading limit, long limit, and right side is that minor face connects minor face, like this, no matter turn left or turn right, two adjacent bottom plates are exactly be symmetrical arranged for line of symmetry with waist limit of aliging; Again because the angle between the waist limit of base plate and long limit is acute angle, the angle between the long limit of that is two adjacent bottom plates is two acute angle sums, and it must be less than 180 degree, therefore the long limit of two base plates is not in the same way, that is to say turn round or turn to.The angle that two base plates turn to is exactly two angles to spreading limit, and the numerical value of this angle equals the twice of the difference at acute angle between waist limit and long limit and right angle, for convenience of describing, this angle is called two body steering angles.When follow-up placement in the same way the 3rd base plate, the angle on the 3rd the long limit of base plate and first long limit of base plate is exactly two body steering angles of twice, that is, whole piece earthquake region and the soil is porous that cable trough circuit that area uses has turned to the angle of two body steering angles of twice; When follow-up placement in the same way the 4th base plate, the angle on the 4th the long limit of base plate and first long limit of base plate is exactly the two body steering angles of three times, that is whole piece earthquake region and the soil is porous that cable trough circuit that area uses has turned to the angle of the two body steering angles of three times, by that analogy, till meeting the requirements of steering angle.In actual applications, because the angle between waist limit and long limit is typically provided to the larger acute angle of numerical value, so make the numerical value of two body steering angles less, that is the steering angle of each follow-up base plate is very little, the object that wide-angle (as 90 degree) turns to so just can be reached by the mode of how placing follow-up base plate in the same way, therefore, this earthquake region and the soil is porous area use turning to of cable trough be very round and smooth, be particularly suitable for single-core cable, optical cable provided underground engineering use.
Short leg near minor face on base plate is provided with two minor face holes, and be fitted with the column vertically arranged in minor face hole, the Lower Half of column is inserted in minor face hole, and the first half of column exposes minor face hole.Short leg is also placed with minor face plate, and minor face plate is upwards extended.Be provided with leghole bottom minor face plate, leghole coordinates with two corresponding plug-in mountings in column top of short leg.Like this, minor face plate, by column and the minor face hole coordinated with column upper and lower plug-in mounting, leghole, not only achieves the connection of minor face plate and base plate short leg, and achieves both location, both position relationships is fixed and uniquely.
Same, base plate is provided with on the long leg on long limit two long lateral opening, long lateral opening in be also fitted with the column vertically arranged, the Lower Half of column be inserted to long lateral opening in, the first half of column exposes long lateral opening.Base plate long leg is also placed with long side plate, and long side plate is upwards extended.Be provided with leghole bottom long side plate, leghole coordinates with two corresponding plug-in mountings in column top of long leg.Like this, long side plate is by column and the length that coordinates with column upper and lower plug-in mounting is lateral opening, leghole, not only achieves the connection of long side plate and base plate short leg, and achieves both location, both position relationships is fixed and uniquely.
Long side plate and minor face plate are by after in stud location to base; minor face plate, long side plate have become " cable trough " of a cross section in " U " shape with base plate with regard to fast construction; and described single-core cable, optical cable etc. are namely laid in this " cable trough ", serve the protective effect to single-core cable, optical cable.
This earthquake region and the soil is porous area use cable trough in, minor face hole and long to be lateral openingly symmetrical arranged relative to the mid line between minor face and long limit, that is, minor face hole and long lateral opening size that to be identical, two minor face holes spacing and two long lateral opening spacing be is isometric, two minor face pitch-rows from spacing and the spacing on two long lateral opening distance limits of minor face be equidistant, minor face hole and length lateral opening be that a left side is right-aligned.
This earthquake region and the soil is porous area use cable trough in, when two reverse placements of base plate, and during the alignment of the waist limit of two base plates, namely a base plate forward is placed a base plate and is oppositely placed, namely the minor face of a base plate docks the long limit of another base plate, when the minor face of another base plate is docked on the long limit of a base plate.Corresponding adjacent minor face hole, docking section (namely docking the waist limit of coincidence) both sides and long lateral opening between spacing equal with the spacing in two minor face holes on same base plate, that is, two minor face holes of two rear homonymies of base plate docking and two long these four same side openings lateral opening are (for convenience of describing, two minor face holes of homonymies after the docking of two base plates and two are longly lateral openingly called same side opening) line track be positioned at same straight line, and four are equal with two adjacent homonymy pitchs of holes any in side opening.The object of such setting is, no matter minor face plate or long side plate can be inserted on any two adjacent homonymy holes on two base plates after docking by column, that is, minor face plate and long side plate not only can be inserted on independent base plate by column, are also inserted into close on docking section two with on side opening by column.Obviously, when minor face plate or long side plate are inserted on independent base plate by column, this minor face plate or long side plate will be carried separately by this base plate.And when minor face plate or long side plate to be inserted into by column two of closing on docking section with on side opening time, this minor face plate or long side plate are then carried jointly by two base plates of this docking, now, due to the relation that is located by connecting of column, this minor face plate or long side plate also have the effect being fixedly connected with this two docking base plate, each docking base plate is fixed together successively, enhance the cohesiveness on each floor length direction or attachment force, effectively ensure that whole piece earthquake region and the soil is porous the structural stability of cable trough circuit that area uses, be particularly suitable in geology soft, yielding or unstable region and earthquake region use.
Base plate is provided with two location notchs be arranged in parallel, and location notch and minor face be arranged in parallel, and location notch two ends penetrate into waist limit and arrange.In this earthquake region and the soil is porous cable trough that area uses, two location notchs are symmetrical arranged relative to the mid line between minor face and long limit, and that is the distance on the minor face that closes on separately of two location notchs distance or long limit is equal.The object of such setting is, no matter two adjacent bottom plates are placed in the same way or reverse placement, can ensure that two location notch correspondences are docking together.Upwards extended dividing plate is fitted with in location notch, the Main Function of dividing plate carries out interval to the electric power such as the single-core cable be layed in " cable trough ", optical cable and communication cable, particularly interval is carried out to three-phase single-core cable, fundamentally stopped the generation of phase fault phenomenon.Minor face plate fastens with long side plate top the cover plate consistent with base plate configuration; after fastening cover plate; " cable trough " and cover plate just constitute " cable tube " of fast demountable, can play the reliable protective effect of upper and lower, left and right four direction to the cable that will lay or optical cable.The shape of cover plate is arranged consistent with base plate configuration, be in order to base plate upper and lower corresponding arrange time, can extend and corresponding extension with the straight line of base plate, or to turn round with base plate smooth and easy and correspondence turn round, so also just accomplish the close docking of " cable tube " end face, effectively avoid laying the soil of the leakage after burying soil, leaking mud phenomenon, ensure that the operation reliably and with long-term of institute's cable laying or optical cable.
This earthquake region and the soil is porous area use cable trough owing to have employed multicompartment fabricated construction, namely whole concrete groove is divided into multiple assembling parts such as base plate, minor face plate, long side plate, dividing plate, cover plate and column, and aforementioned each assembling parts assembled in situ is become " cable tube " of cable laying required for construction or optical cable by assembling mode.Therefore, when depositing or transport, can by batch bundling, the packing respectively of each assembling parts, such as, after being superposed by multiple base plate batch bundling, packing, pack bundling after the superposition of multiple minor face plate batch, etc.After bundling, packing, each assembling parts in bundle or in bag is snug fit, and the gap between each assembling parts is very narrow and small, almost negligible.And prefabricated high voltage cable groove traditional is at present cross section is the Integral hollow frame structure of " U " shape, anything can not be placed in hollow support body when depositing or transport, therefore hollow bracket body structure occupies large quantity space, not only deposit footprint area large, and conevying efficiency is extremely low, in transportation, hollow bracket body structure is very easily damaged, and percent defective is high, and cost of transportation also must improve.Therefore, this earthquake region and the soil is porous area use cable trough take up room little, convenient transportation, efficiency are high, breakage rate is low, cost is low, contribute to reduce construction cost.
