Description

Technical Field

[0001] The present application relates to the field of road drainage, and in particular to a municipal road drainage construction structure and a construction method thereof. Background Art

[0002] In the process of urbanization, municipal roads are an important part. With the acceleration of urban development, the coverage of municipal roads is getting larger and larger. In order to quickly drain the rainwater on municipal roads, drainage wells are usually installed on the road surface to discharge rainwater and sewage to avoid the formation of water accumulation and ensure normal traffic on the road.

[0003] The drainage well mainly includes a well body and a drainage pipe. In the related technology, the drainage well is usually formed by waterproof bricks. When building the drainage well, it is necessary to cast a waterproof concrete pallet at the bottom of the foundation, and then put the end of the drainage pipe on the waterproof concrete pallet, and finally build the well body with waterproof bricks on the waterproof concrete pallet to form a drainage well. After the drainage well is built, it is necessary to take sealing measures at the junction of the drainage pipe and the well body, and the inner and outer walls of the well body also need to be coated with corresponding waterproof coatings to improve the anti-water seepage ability.

[0004] Regarding the above-mentioned related technologies, the inventor believes that the method of building drainage wells with waterproof bricks is time-consuming and labor-intensive, and maintenance work of more than a week is required after the construction is completed, resulting in low construction efficiency of existing municipal road drainage structures, which needs to be improved. Summary of the invention

When the drainage well selects one-way, two-way or three-way according to needs (that is, the drainage well is only connected to one drainage pipe, two drainage pipes or three drainage pipes), the cover plate is inserted into the installation hole so that the positioning hole and the through hole are aligned. While the positioning rod passes through the through hole and the through hole, the remaining positioning rods pass through the through hole and the positioning holes to position the cover plate. The installation hole to which the drainage pipe is not plugged can be blocked by the cover plate, so that the base and the well body only need to be produced in one specification, avoiding excessively high mold opening costs. The well body, drainage pipe, base and cover plate can all be prefabricated in the factory and then transported to the construction site for assembly, which can greatly improve construction efficiency and reduce labor costs. At the same time, it is convenient for later disassembly and recycling.

When the slider is inserted into the sliding groove, the filling groove 1 and the filling groove 2 are aligned.

[0016] By adopting the above technical solution, filling groove one and filling groove two are set. When the adjacent drainage pipes are connected and the soil is subsequently backfilled, the soil will fill the filling groove one and filling groove two, thereby suppressing the relative displacement between the ring one and the ring two. As time goes by, the soil will gradually settle and become dense, and the resistance to the relative displacement between the ring one and the ring two will become greater and greater, further suppressing the movement between the ring one and the ring two, thereby improving the stability of the connection between the adjacent drainage pipes.

A through hole 124 is provided on the inner wall of each mounting hole 122 away from the through hole 123. The through hole 123 and the through hole 124 are both for the positioning rod 3 to pass through.

[0040] See also Figure 1 and Figure 3A water hole 21 is provided on the end surface of the drain pipe 2, and the water hole 21 penetrates the drain pipe 2 along the length direction of the drain pipe 2. Two through holes 22 are provided on the outer wall of the drain pipe 2. The two through holes 22 are respectively located at opposite ends of the drain pipe 2, and the through hole 22 penetrates the drain pipe 2 in a direction perpendicular to the length direction of the drain pipe 2. The through hole 22 is connected to the water hole 21, and the positioning rod 3 is passed through the through hole 22.

[0041] See also Figure 2-5 The connection assembly 14 is used to connect adjacent drain pipes 2. The connection assembly 14 includes a collar 141, a collar 2 142 and two plugs 143. The collar 141 and the collar 2 142 are spliced ​​to form a clearance hole 4. The clearance hole 4 is for the drain pipe 2 to pass through. When the drain pipe 2 passes through the clearance hole 4, the outer wall of the drain pipe 2 fits the inner wall of the clearance hole 4. The two opposite end faces of the collar 1 141 are provided with a slide groove 1411. The same end of the two slide grooves 1411 passes through the collar 1 141. A slider is fixed on the collar 2 142. 5. The number and position of the sliders 5 correspond to the number and position of the slide grooves 1411. The slide grooves 1411 are for the corresponding sliders 5 to slide and insert along the length direction of the drain pipe 2. The collar 141 and the collar 2 142 are detachably connected through the sliding fit between the slider 5 and the slide grooves 1411. In this embodiment, the slider 5 is a dovetail block, and the slide grooves 1411 are dovetail grooves that cooperate with the slider 5. The two plug blocks 143 are both located in the clearance hole 4 and are spaced apart along the length direction of the drain pipe 2. The through holes 22 are for the plug blocks 143 to pass through.

[0042] In actual use, when it is necessary to connect adjacent drain pipes 2, the two plug blocks 143 on the ring 141 are respectively inserted into the through holes 22 on the two adjacent drain pipes 2, and then the slider 5 on the ring 2 142 is slidably inserted into the corresponding slide groove 1411 on the ring 1 141 to achieve the connection between the ring 1 141 and the ring 2 142, and the ring 1 141 is limited by the ring 2 142 abutting against the drain pipe 2, and the connection between the two adjacent drain pipes 2 is achieved by the plug block 143 abutting against the inner wall of the through hole 22.

[0043] See also Figure 4Two filling grooves 1412 are provided on the outer wall of the ring 141. The two filling grooves 1412 are both located on the side of the ring 141 away from the second ring 142 and are respectively located at the opposite ends of the ring 141, and the filling groove 1412 penetrates the ring 141 in the direction close to the second ring 142. Two filling grooves 1421 are provided on the outer wall of the second ring 142. The two filling grooves 1421 are both located on the side of the ring 142 away from the first ring 141 and are respectively located at the opposite ends of the second ring 142, and the filling groove 1421 penetrates the second ring 142 in the direction close to the first ring 141. When the slider 5 is inserted into the sliding groove 1411 and abuts against the inner wall of the sliding groove 1411, the filling groove 1412 and the filling groove 1421 are aligned.

[0044] In actual use, when the adjacent drainage pipes 2 are connected and subsequently backfilled with soil, the soil will fill the filling groove 1 1412 and the filling groove 2 1421, thereby suppressing the relative displacement between the ring 1 141 and the ring 2 142 and improving the stability of the connection between the adjacent drainage pipes 2.

[0045] See also Figure 1-4 A convex ring 6 is fixed on the outer wall of the main body 12, and the number and position of the convex ring 6 correspond to the number and position of the mounting holes 122. Each convex ring 6 is arranged around the outer periphery of the corresponding mounting hole 122. A sealing ring 7 is fixed on the drain pipe 2, and the number and position of the sealing ring 7 correspond to the number and position of the through holes 22 on the drain pipe 2. Each sealing ring 7 is located on the side of the corresponding through hole 22 close to another through hole 22 on the drain pipe 2, and the sealing ring 7 is sleeved on the outer side of the drain pipe 2. When the positioning rod 3 is inserted into the through hole 22, the sealing ring 7 abuts the convex ring 6. When the insert block 143 is inserted into the through hole 22, the two sealing rings 7 close to each other on the two adjacent drain pipes 2 abut against the ring 1 141 and the ring 2 142. By providing the convex ring 6, the structural strength of the connection between the well body 1 and the drain pipe 2 is improved. By providing the sealing ring 7, the sealing performance of the connection between the well body 1 and the drain pipe 2 and the adjacent drain pipes 2 is improved. In this embodiment, the material of the sealing ring 7 is rubber.

[0046] It should be pointed out that a groove (not shown in the figure) for accommodating the sealing ring 7 is provided on the outer wall of the drain pipe 2. When the slider 5 is moved into the slide groove 1411 or the slider 5 is moved out of the slide groove 1411, the sealing ring 7 can be squeezed to make the sealing ring 7 enter the groove, thereby facilitating the movement of the slider 5. Therefore, the setting of the sealing ring 7 will not jam the slider 5 and cause the slider 5 to be unable to move.

[0047] See also Figure 3 and Figure 6The cover plate 13 includes a plate body 131 and a snap-in portion 132. The plate body 131 is provided with a receiving groove 1311, and the receiving groove 1311 is for the convex ring 6 to be snapped in. The snap-in portion 132 is located in the receiving groove 1311 and is fixedly connected to the plate body 131. The water hole 21 and the mounting hole 122 are both for the snap-in portion 132 to be snapped in. When the snap-in portion 132 is snapped into the water hole 21, the snap-in portion 132 fits the inner wall of the water hole 21 and is rotatably connected to the drain pipe 2. 2 and the rotation axis of the drain pipe 2 are parallel to the length direction of the drain pipe 2. When the snap-in portion 132 is snapped into the mounting hole 122, the convex ring 6 is snapped into the accommodating groove 1311. The convex ring 6 abuts against the inner circumferential wall of the accommodating groove 1311, thereby limiting the snap-in portion 132. A positioning hole 1321 is provided on the outer side wall of the snap-in portion 132. The positioning hole 1321 penetrates the snap-in portion 132 along the radial direction of the snap-in portion 132. The positioning hole 1321 is for the positioning rod 3 to pass through.

[0048] See also Figure 2-8 A limiting block 8 is fixed on the inner wall of the water hole 21, and the number and position of the limiting blocks 8 correspond to the number and position of the through holes 22. The two limiting blocks 8 are respectively located at the opposite ends of the water hole 21 and at the opposite sides of the water hole 21. A card slot 1322 is provided on the outer wall of the card-in portion 132. The card slot 1322 penetrates the card-in portion 132 in a direction away from the plate body 131. A card slot 2 1323 is provided on the inner wall of the card slot 1322. The card slot 2 1323 is provided on the inner wall of the card slot 1322. 23 is located on one side of the slot 1 1322 along the rotation direction of the snap-in portion 132, and both the slot 1 1322 and the slot 2 1323 are for the limit block 8 to be snapped in. A cavity 9 is also provided in the snap-in portion 132. When the limit block 8 is snapped into the slot 2 1323, the positioning hole 1321 and the through hole 22 are staggered, and the cavity 9 is located above the axis of the snap-in portion 132. The center of gravity of the cover plate 13 is changed by providing the cavity 9, so that the limit block 8 remains in the state of being located in the slot 2 1323.

[0049] In actual use, during construction, when the drain pipe 2 is installed on the well body 1, the snap-in portion 132 can be snapped into the end of the water hole 21 away from the well body 1, so that the limit block 8 is snapped into the first snap-in groove 1322, and then the plate body 131 is rotated to drive the snap-in portion 132 to rotate, so that the limit block 8 is snapped into the second snap-in groove 1323. At this time, the positioning hole 1321 and the through hole 22 are staggered, thereby blocking the drain pipe 2, which can reduce the situation where sewage or debris enters the construction area through the well body 1 and the drain pipe 2, thereby affecting the progress of the construction. When the drain pipe 2 is connected later, the cover plate 13 can be taken out, and local materials are used, and the operation is convenient.

[0050] The implementation principle of a municipal road drainage construction structure in the embodiment of the present application is: When building a drainage well, first install the base 11, then insert each drainage pipe 2 into the installation hole 122 so that the through hole 22 and the through hole 123 are aligned, and then move the well body 1 and each drainage pipe 2 so that the positioning rod 3 passes through the through hole 123 and the through hole 22 to complete the connection between the drainage pipe 2 and the well body 1.

[0051] When the drainage well selects one-way, two-way or three-way as needed (that is, the drainage well is only connected to one drainage pipe 2, two drainage pipes 2 or three drainage pipes 2), the snap-in portion 132 is snapped into the installation hole 122 to align the positioning hole 1321 with the through hole 123. While the positioning rod 3 is penetrated by the through hole 123 and the through hole 22, the remaining positioning rods 3 are penetrated by the through hole 123 and the positioning hole 1321 to position the cover plate 13. The installation hole 122 to which the drainage pipe 2 is not plugged can be blocked by the cover plate 13, so that the base 11 and the well body 1 only need to be produced in one specification, avoiding excessively high mold opening costs. The well body 1, the drainage pipe 2, the base 11 and the cover plate 13 can all be prefabricated in the factory and then transported to the construction site for assembly, which can greatly improve construction efficiency and reduce labor costs. At the same time, it is convenient for later disassembly and recycling.

[0052] The drainage pipe 2 can also be connected by the connecting component 14 as needed to obtain "drainage pipes 2" of different lengths, which can be built in conjunction with the well body 1 to construct drainage systems of different routes. It has high applicability, so that the drainage pipe 2 only needs to be produced in one specification, and there is no need to prefabricate drainage pipes 2 of different specifications according to the area of ​​the construction area, which avoids excessively high mold opening costs and is conducive to further reducing costs.

[0053] The present application also discloses a construction method for the municipal road drainage construction structure as described above, comprising the following steps: S1. First, the base 11 is fixed to the foundation by anchoring, and then a waterproof coating covering the anchor rod is applied inside the base 11; S2. Insert each drain pipe 2 into the installation hole 122 and align the through hole 123 with the through hole 22, and insert the cover plate 13 into the remaining installation holes 122 as needed so that the through hole 123 and the positioning hole 1321 are aligned, and then move the well body 1 and each drain pipe 2 and the cover plate 13 so that the positioning rod 3 passes through each through hole 123, and the installation of the drain pipe 2 and the cover plate 13 is completed; S3. If the drain pipe 2 is not long enough, the adjacent drain pipes 2 are connected by connecting components 14; S4. Spray a waterproof coating on the inner and outer walls of the well body 1, and backfill with soil to form a roadbed.

[0054] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
