And a lid lock 5 that can be attached and detached in an opening space 4 formed between the lid members 3 placed on the portion.

  As shown in FIG. 2, the side groove main body 2 has left and right side wall portions 7a and 7b erected upward from the left and right sides of the bottom portion 6. Between the bottom portion 6 and the left and right side wall portions 7a and 7b, The wiring through space 8a and the drainage channel through space 8b are formed in a state in which at least both the spaces are arranged in parallel on the left and right sides and are separated by a partition wall 7c, and the bottom 6 and the left and right side walls are formed. 7a, 7b and the partition wall 7c are integrally molded, and the upper surface of the joint wiring through space 8a opens as the upper opening 9a with the same width as the width of the through space 8a. The upper surface of the through hole 8b is a concrete casing that is opened as a rainwater inlet 9b in a slit shape narrower than the width of the through hole 8b. Then, the width of the joint wiring through space 8a from above is used as a lid support portion for supporting the lid member 3 on the inner side of the side wall portion 7a and the partition wall 7c standing on both sides of the joint wiring through space 8a. A raised ridge 12 having an inclined surface 11 that gradually narrows downward is formed in the longitudinal direction, and an engaging portion 13 of the lid member 3 supported by the lid support portion is provided in the middle of the ridge 12. A recess 14 is formed which functions as a movement preventing portion that is locked to the lid member 3 to prevent the lid member 3 from shifting in the longitudinal direction of the lateral groove body 2. Specifically, as shown in FIG. 3, a concave portion 14 is formed by notching the inclined surface 11 of the ridge 12, and this concave portion 14 is used to lock the lid member 3 to be described later. The portion 13 is formed in a position and a size that do not shift from just fitting from above. In the embodiment shown in the drawings, a curb 15 serving as a boundary between the roadway side and the sidewalk side is provided at the upper end of the partition wall 7c.

As shown in FIGS. 4 and 5, the lid member 3 is a substantially rectangular concrete plate material, and the lower part of the side edge that is a long side is chamfered from both ends in the longitudinal direction to the middle before the center, and is inclined downward A locking portion 13 is formed which forms a surface 20 and protrudes relative to the lower inclined surface 20 by not chamfering between the lower inclined surfaces 20, that is, in the central portion of the lower portion of the side edge. ing. The lower inclined surface 20 may be configured with a flat surface (FIG. 4) or a curved surface (FIG. 5) according to the inclined surface 11 of the side groove main body 2.
Further, the lid member 3 has a first meshing portion 21 in which the lower half side of the thickness of the lid member 3 protrudes relative to the upper half side on one end face (surface orthogonal to the longitudinal direction, end face). A second meshing portion 22 is formed on the other end face, with the upper half side of the thickness protruding relative to the lower half side. Accordingly, when the lid member 3 having such a structure is sequentially covered in one row with the wife surfaces facing the upper opening 9a of the side groove body 2, the side groove body 2 has the above-described structure as shown in FIG. A lower inclined surface 20 of the lid member 3 is placed on the inclined surface 11 of the lid support portion, and a locking portion 13 having a length C formed between the two lower inclined surfaces 20 is placed in the recess 14 of the side groove body 2. The lid member 3 is not displaced in the longitudinal direction of the side groove main body 2 by this fitting. Further, when the lid members 3 are arranged adjacent to each other along the longitudinal direction of the side groove main body 2, the first meshing portion 21 enters and meshes below the second meshing portion 22, and the second meshing portion 22 is the first meshing portion. It will be in the meshing state which controls the movement of 21 upwards. In this embodiment, the length L of the side groove main body 2 is set to the length A of the lid member 3 and the cover member 3 is covered with four pieces of the cover material 3 so that the upper opening 9a of the side groove main body 2 is opened to the length B. Each dimension is set so that a space 4 is generated. And the opening space 4 of this length B is obstruct | occluded with the lid | cover lock tool 5, and it prevents that the lid | cover material 3 and the lid | rock lock tool 5 are lifted carelessly. The length C ′ of the recess 14 formed in the side groove body 2 and the length C of the locking portion 13 formed on the lid member 3 are substantially the same length, more precisely, the length C ′ of the recess 13 is the same. It is set to be slightly longer and is set to a size that will fit naturally and not shift. Therefore, even if the main groove material 1 is buried in an inclined area, the inconvenience that the lid member 3 is shifted due to the inclination even when an earthquake occurs or the automobile is vibrated can be prevented.

  The lid locking device 5 is generally configured by an upper surface portion 25 that closes the opening space 4 in the mounted state of the side groove body 2 and the locking lock portion 26 that locks in the mounted state. When the locking lock portion 26 is locked in the mounted state, it is handed around the upper surface portion 25, between the lid materials 3, between the lid material 3 and the side groove body 2 (upper ends of the side wall portions 7 a and 7 b 7). In this way, the gap where the tool is inserted is closed, and thereby the lid member 3 is restricted from being arbitrarily moved upward (that is, opened) without removing the lid lock 5. More specifically, in the present embodiment, the upper surface portion 25 of the lid lock 5 is adjusted to the size of the opening space 4 of the upper opening 9a of the side groove body 2 (long to the width of the upper opening 9a). It is made of an iron plate (the length of the side and the length of the short side are set), the top surface is formed with unevenness that serves as anti-slip and suction cup prevention, and the lock operation opening 30 is opened in the center of the top surface ing. A frame 31 in which square steel is assembled in a lattice shape as a reinforcing material is fixed below the upper surface portion 25, and the upper surface portion 25 becomes the same height as the upper end surface of the gutter body 2 when attached to both ends of the frame 31. Thus, the raised portion 32 is provided, and the lock portion 33 is provided in the central portion.

  The locking portion 33 has a U-shaped bracket 34 pivotally attached to the lower surface of the substantially central flat portion of the frame 31 in a downward and pivotable manner, and a strip as a locking tool at the lower end of the bracket 34. An operation portion 36 that can be rotated by a special tool is provided at the upper end of the shaft on which the bracket 34 is fixed. In this embodiment, the head of the hexagonal bolt is welded and fixed to the lower surface of the bracket 34 so that the male screw portion protrudes upward to form a shaft, and the outer shape is substantially triangular at the tip of the male screw portion protruding upward from the bracket 34. The cap nut is fixed, and the cap nut is used as the operation portion 36.

  Further, the locking metal fitting 35 is made of a long material (plate material) that is longer than the dimension of the upper surface part 25 in the penetration direction of the through space and narrower than the dimension of the opening space 4 in the penetration direction. The center portion of the bracket 34 is fixed to the lower end of the bracket 34, and is rotated about the axis of the bracket 34. It is configured so that it can be converted into a release state that does not protrude, and in the locked state, it can contact the rod-shaped stopper 37 provided at the target position across the shaft to maintain the locked state, and rotate in the opposite direction. When converted to the release state, the release state is maintained by contacting the opposite side of the stopper 37. In the present embodiment, as shown in FIG. 7, the first engagement portion 21 of the lid member 3 is placed under the frame 31 in a state where the lid lock tool 5 is adjacent to the end face of the lid member 3. In this state, the size and arrangement of the frame 31, bracket 34, stopper 37, etc. are such that the recessed surface of the upper half of the lid member 3 abuts against the upper surface portion 25, thereby adjoining until there is no gap. It is set appropriately. Although not shown in the drawings, the locking bracket 35 is inclined to the side edge portion on the lid member 3 side so that the locking bracket 35 slides on the lower surface of the lid member 3 and is smoothly locked. A guide surface may be formed.

Next, the construction of the gutter material 1 having the above-described configuration will be described.
Although not shown in the drawings, a foundation is formed by placing foundation crushed stone and foundation concrete at the bottom of a laying groove that has been excavated in the ground, and the side groove body 2 is placed on the foundation in the direction in which the groove extends. A plurality of the grooves are embedded in a row along the side, adjacent side groove bodies 2 are sequentially joined together by a side joint (not shown) or the like, and then the grooves are backfilled. In the present embodiment, the curb 15 located at the upper end of the partition wall 7c is located at the boundary between the roadway and the sidewalk, the drainage passage through space 8b is on the roadway side, and the common wiring through space 8a is on the sidewalk. The side groove body 2 is embedded so as to be located on the side.

  When the side groove main body 2 is embedded in the groove in this way, the joint wiring through cavities 8a of each side groove main body 2 are in a series, and the upper surface is open to the sidewalk side. 8b also forms a series of slit-shaped rainwater inlets 9b that open to the roadway side. Therefore, a power line, a telephone line, a communication cable, etc. can be accommodated inside the joint wiring through space 8a which is a series from the sidewalk opening.

  Then, when the operations such as storage of various wirings and cables are completed, the upper opening 9a of each side groove main body 2 is covered with the lid member 3 to close it. In the embodiment shown in FIG. 1, when covering the cover member 3, when the cover member 3 is covered on the left end of the side groove main body 2, the side groove main body 2 with the second meshing portion 22 protruding from the upper half facing the left side. The upper cover 9a is covered, and the next cover 3 is directed to the right side of the cover 3, and the second fitting part 22 with the upper half protruding is directed to the left. In this state, the upper side opening 9a of the gutter body 2 is covered, and the second fitting portion 22 on the left side is placed on the first meshing portion 21 on the right side of the lid portion 4 that has been covered first. 21 and the 2nd fitting part 22 are meshed | engaged. Next, when covering the cover material 3 on the right side on the opposite side, the first engagement portion 21 protruding from the upper half is covered on the upper opening 9a of the side groove main body 2 in the state of facing the right side. Next, the second fitting part 22 with the upper half protruding is directed to the right side, and the upper side opening 9a of the gutter body 2 is covered in this state, and the second fitting part 22 on the right side is The first fitting portion 21 and the second fitting portion 22 are engaged with each other by being placed on the first fitting portion 21 on the left side of the lid member 3 covered with the cover member 3. In this way, when the cover materials 3 are covered two by two in order from the left and right ends, an opening space 4 is formed in the center of the upper opening 9a so that the lid lock 5 is just fitted.

If the lid member 3 is sequentially covered on the upper opening 9a of the side groove main body 2 in this manner, the lid lock 5 is mounted next.
When the lid locking device 5 is mounted, the locking member 35 is stored below the upper surface portion 25 and maintained in a released state in which it does not protrude and descends toward the opening space 4 of the side groove body 2, and FIG. As shown in FIG. 7, the raised portion 32 provided at the end of the upper surface portion 25 is placed on the inclined surface 11 of the lid support portion of the side groove body 2, and the longitudinal portion of the frame 31 is closed as shown in FIG. 7. By placing on the first meshing portion 21 of the material 3, the upper surface portion 25 can close the opening space 4 at the same height as the upper end of the side groove body 2 with almost no gap. Then, as shown in FIG. 6 (c), when the operation portion 36 is rotated using a special tool, the locking bracket 35 is rotated and the tip portion thereof is moved to the lower surface of the lid member 3 to be in a locked state. When converted and sufficiently rotated, the locking fitting 35 comes into contact with the stopper 37 and stops as shown in FIG. In this locked state, there is no gap around which the tool or finger can be inserted around the lid lock 5, and furthermore, since the locking fitting 35 hits the lower surface of the lid 3, the lid lock 5 cannot be lifted and removed. Furthermore, even if it is going to lift the cover material 3 adjacent to the lid lock 5, the first meshing portion 21 in the lower half of the cover 3 hits the frame 31 of the lid lock 5 and cannot be lifted. Furthermore, even if it is intended to lift the adjacent lid member 3, that is, the lid member 3 positioned away from the lid locking device 5, the first engagement portion 21 located on the lid locking device 5 side of the lid material 3 is adjacent. Since it is restrained by the second meshing portion 22 of the lid member 3, it cannot be lifted. Accordingly, when the cover lock 5 is put on and converted to the locked state, the cover lock 5 and the cover 3 cannot be unreasonably lifted and removed in this locked state. For this reason, high security can be expected. When the lid 3 is to be lifted illegally, for example, an L-shaped piano wire is placed between the side edge in the longitudinal direction of the lid 3 and the upper ends of the side wall portions 7a and 7b7 of the side groove body 2. Even if it tries to insert from a slight gap, the inclined surface 11 of the raised ridge 12 of the side groove main body and the bottom of the recess 14 can prevent intrusion. Moreover, even if it is going to insert from the slight clearance which the wife surfaces of the cover material 3 faced, the 1st meshing part 21 of the cover material 3 can prevent intrusion.

  On the other hand, when it becomes necessary to work on the telephone line or the like at a later date, the once-locked lid lock 5 is removed. As an operation in this case, first, using a special tool, the operating portion 36 is rotated to the opposite side to the locking operation, and the locking metal fitting 35 positioned on the lower surface of the lid member 3 is moved to the lower surface of the lid member 3. From the locked state to the unlocked state. When converted to the unlocked state in this way, the lid lock 5 can be lifted and removed. When the lid lock 5 is removed in this way, an opening is created in the central portion of the gutter body 2, and a hand or a tool is inserted into the opening, and the lid 3 adjacent to the opening is lifted (raised) and removed. Can do. At this time, there is nothing that prevents the first meshing portion 21 protruding from the end face of the lid 3 from rising, so that it can be lifted and removed without hindrance. Then, the next lid member 3 can be removed in the same manner because there is no obstacle to the rise. If this removal operation is repeated, all the lid members 3 can be removed from the series of side groove main bodies 2, and the work in the joint wiring through space 8 a can be made possible. When the work is completed, the lid 3 and the lid lock 5 are covered by the above-described operation to close the upper openings 9a of the side groove main bodies 2, and the lid 3 and the lid lock 5 are It can be locked without any gaps around it.

In the above-described embodiment, the lid member 3 is placed on the lid lock 5 with the wife surface from which the lower half of the lid member 3 protrudes, but the present invention is not limited to this.
For example, in the embodiment shown in FIG. 8, with respect to one adjacent lid member 3 of the lid lock tool 5, the first meshing portion 21 in which the lower half of the wife surface protrudes faces the lid lock tool 5, and the other adjacent one. Regarding the lid member 3, the second meshing portion 22 projecting from the upper half of the end face is directed to the lid lock 5, and each lid member 3 is covered in the same direction on the upper opening 9 a of the side groove body 2. In this way, there is no gap between each lid member 3 and the lid lock fitting 5 where a hand or a tool can enter, so that it is possible to prevent the lid member 3 and the lock fitting from being inadvertently lifted, and security. It contributes to the improvement. Further, when such a lid member 3 is arranged, the lid member 3 can be covered in the same direction on the series of upper openings 9a of the connected side groove bodies 2, and the lid member of the adjacent side groove body 2 can be covered. 3 can also be covered with the first meshing portion 21 and the second meshing portion 22 meshed. Therefore, even if it is the cover material 3 in the middle, it can prevent more reliably that it is lifted independently by the said meshing.

  Further, in another embodiment shown in FIG. 9, with respect to one adjacent cover member 3 of the lid lock tool 5, the second engagement portion 22 from which the upper half of the wife surface protrudes is directed to the lid lock tool 5, and the other As for the adjacent lid members 3, each lid member 3 is covered with the upper opening 9 a of the side groove main body 2 with the second engagement portion 22 projecting from the upper half of the end face facing the lid lock 5. Even if it arrange | positions in this way, since the clearance gap which a hand and a tool can enter does not arise around each lid | cover material 3 and the lid | rock lock tool 5, the lid | cover material 3 and the lid lock tool 5 can be raised carelessly. Can contribute to improving security.

  In the above-described embodiment, the joint wiring through space 9a and the drainage channel through space 8b are arranged side by side so that the through holes 8a and 8b do not overlap in plan view. Is not limited to this, and it is only necessary that the two through-spaces 8a and 8b are arranged side by side in the left-right direction (width direction). In addition, the cross-sectional shapes of the joint wiring through-hole 8a and the drainage flow-through through-hole 8b can be set as appropriate, and the size of the cross-sectional area can be set according to the demand at the site. That's fine.

  For example, in the second embodiment of the side groove main body 2 shown in FIG. 10, when viewed from one end surface of the side groove main body 2, the cross-sectional shape is substantially circular, and the drainage flow having a slit-shaped rainwater inlet 9b opened on the upper surface. The road through-space 8b is disposed at the upper right in the drawing, and the partition wall 7c is directed from the middle to the top in the middle of the height of the side wall 7b on the drainage flow-path through-space 8b side (that is, the drainage Standing in a state where the flow passage through-hole 8b is wrapped from the bottom to the top) and extending to the lower side of the left and right sides in the figure (that is, to the lower side of the drainage flow channel penetration) A lateral opening 9c is formed in the upper side surface of the joint wiring through-hole 8a which is formed by enlarging the void 8a and has a substantially trapezoidal cross-sectional shape. In addition, since this horizontal opening part 9c is opened over the full length of the side surface of the side groove | channel main body 2, when it embed | buries while connecting the some side groove | channel main body 2, the penetration empty part 8a for joint wiring of each side groove | channel main body 2 and drainage | drain Not only the flow-through through-hole portions 8b communicate with each other in series, but also the lateral opening portions 9c of the side groove bodies 2 open in a series of horizontally long shapes. In this way, when the through hole 8a for the joint wiring is opened on the side surface of the side groove body 2, the groove is excavated a little wider at the time of embedding, and various long wires and cables can be opened from the lateral opening 9c. It can be easily put inside the portion 8a. When the various wirings are stored and the lateral opening 9c is covered with a lid 42, and then the groove is backfilled, a tool or the like cannot be put into the joint wiring through space 8a after the construction is completed. , Security can be further improved. In addition, since the lid material is not exposed on the upper surface of the gutter main body 2, the finished surface is smooth and does not hinder pedestrians. Furthermore, in the present embodiment, the volume ratio of the joint wiring through space 8a and the drain passage through space 8b can be greatly adjusted as compared with the case where both the through spaces are simply arranged side by side. It is possible to provide the side groove material 1 adapted to the actual situation, and it is possible to improve the space efficiency and rationalize the construction.

In the third embodiment of the side groove main body 2 shown in FIG. 11, the lower part (part) of the joint wiring penetration space 8 a enters under the drainage flow passage penetration space 8 b, and both penetrations are seen in plan view. Although it is the same as that of the second embodiment in that a part of the vacant portion is arranged so as to overlap vertically, the upper surface of the joint wiring penetration vacant portion 8a is opened, and the drainage passage penetration vacancy of this opening is provided. The lid support part 43a formed on the side of the part 8b is formed at a position higher than the lid support part 43b at the upper end of the side wall part 7a located on the opposite side. That is, the lid support part 43a on the drain passage through space 8b side of the lid support part is formed at a position higher than the other lid support parts 43b. The lid support portion 43a provided on the partition wall 7c side is similarly formed with the inclined surface 11 and the recess 14 in the first embodiment described above, and the length of the through space 8a of the lid 3 '. The movement (shift) in the direction is prevented. Further, the lid support portion 43b provided at the upper end of the opposite side wall portion 7a is formed in a step shape that is one step lower on the side of the joint wiring through space 8a.
For this reason, the upper surface of the joint wiring through-hole 8a is inclined and opened. Therefore, when the lid 3 'is opened after being buried and maintenance work for wiring and cables is performed, the opening is inclined as in the present embodiment compared to the case where the opening is opened horizontally. The work operation range is increased and the work can be facilitated.

  As shown in FIG. 11, the lid member 3 ′ is schematically composed of a flat portion 44 a that closes the upper opening substantially horizontally and a leg portion 44 b that protrudes downward from one end of the flat portion 44 a. Similarly to the lid member 3 described above, the flat surface portion 44a is formed on the side edge on the drainage passage through-hole 8b side, on the slope and the concave portion mounted on the lid support portion 43a formed at a high position of the side groove main body 2. It has a locking portion (not shown) to be fitted, and a leg portion 44b is suspended from the opposite side edge. The leg portion 44b is in a meshed state engaged with a lid support portion 43b formed at the upper end of the side wall portion 7a of the side groove body 2 described above, that is, the joint wiring penetrating space 8a side protrudes one step downward. A stepped locking edge is formed. Therefore, the lid member 3 ′ is placed on the upper opening of the side groove main body 2, and the lower end of the leg portion 44 b is locked on the lid support portion 43 b of the side wall portion 7 a of the side groove main body 2. When it is placed in the state (engaged state) and the opposite side edge is placed on the lid support portion 43a of the partition wall 7c of the side groove main body 2 and the engaging portion is engaged with the recess, the lid member 3 is engaged by this engagement. The movement in the longitudinal direction of ′ is restricted, and the movement in the width direction of the lid member 3 ′ is restricted by the engagement of the above-described concave and convex steps. For this reason, it is possible to prevent the cover member from shifting even if there is an earthquake, vibration of an automobile, a train or the like.

By the way, it should be thought that above-described embodiment is an illustration and restrictive at no points. The present invention is not limited to the above description, but is defined by the scope of the claims, and includes all modifications within the scope and meaning equivalent to the scope of the claims.
For example, the cross-sectional shape of the drainage passage through-hole 8b is not limited to the circular water channel having the slit-shaped rainwater inflow port 9b, and can be appropriately selected such as a U-shape. Further, a thin portion 45 may be provided on the outer side surfaces of the side wall portions 7a and 7b of the side groove main body 2 so that when the cable or the like is branched, the thin portion 45 is easily broken and the branched cable is passed. In particular, as shown in FIG. 10 and FIG. 11, when the joint wiring through space 8 a is formed so as to extend below the drain flow channel through space 8 b, the cable or the like is branched to either the left or right side of the side groove material 1. For example, it is convenient to install street lights and traffic lights. Although not shown in the drawings, a drainage hole (not shown) may be appropriately provided at the bottom of the joint wiring through-hole 8a.
