Description

Technical Field

[0001] This application relates to the field of road drainage, and in particular to a construction structure and construction method for municipal road drainage. Background Technology

[0002] In the process of urbanization, municipal roads are an important component. As the speed of urban development accelerates, the coverage of municipal roads is also increasing. In order to quickly drain rainwater from municipal roads, drainage wells are usually installed on the road surface to discharge rainwater and sewage, so as to avoid water accumulation and ensure normal traffic flow.

[0003] A drainage well mainly consists of a well body and a drainage pipe. In related technologies, drainage wells are usually constructed by building with waterproof bricks. When building a drainage well, a waterproof concrete support plate needs to be poured at the bottom of the foundation. Then, the end of the drainage pipe is placed on the waterproof concrete support plate. Finally, waterproof bricks are laid on the waterproof concrete support plate to construct the well body, thus forming a drainage well. After the drainage well is built, sealing measures need to be taken at the junction of the drainage pipe and the well body. Appropriate waterproof coatings also need to be applied to the inner and outer walls of the well body to improve the water-proofing ability.

[0004] Regarding the aforementioned technologies, the inventors believe that using waterproof bricks to build drainage wells is time-consuming and labor-intensive, and requires more than a week of maintenance after construction, resulting in low construction efficiency of existing municipal road drainage structures, which needs to be improved. Summary of the Invention

[0005] In order to improve the construction efficiency of municipal road drainage structures, this application provides a municipal road drainage construction structure and its construction method.

[0006] Firstly, this application provides a municipal road drainage construction structure, which adopts the following technical solution:

[0007] A municipal road drainage construction structure includes a well body and a drainage pipe. The drainage pipe has a water passage hole. The well body includes a base, a main body, a cover plate, and a connecting assembly. The base is provided with several positioning rods. The main body has a water inlet and several mounting holes. The mounting holes are located on various sides of the main body and communicate with the water inlet. The mounting holes are for the drainage pipe / the cover plate to be inserted. The bottom wall of the main body also has a through hole that communicates with the mounting holes. The outer wall of the drainage pipe has a through hole that communicates with the water passage hole. Both the through hole and the through hole are for the positioning rods to pass through. The cover plate has a positioning hole for the positioning rods to pass through. The connecting assembly is used to connect adjacent drainage pipes.

[0008] By adopting the above technical solution, when constructing a drainage well, the base is first installed, and then each drainage pipe is inserted into the installation hole, aligning the through hole and the perforation. Next, the well body and each drainage pipe are moved so that the positioning rod passes through the perforation and the through hole, thus completing the connection between the drainage pipe and the well body. When the drainage well is selected as a one-way, two-way, or three-way (i.e., the drainage well connects only one, two, or three drainage pipes), the cover plate is inserted into the installation hole, aligning the positioning hole and the perforation. While the positioning rod passes through the perforation and the through hole, other positioning rods pass through the perforation and the positioning hole to position the cover plate. The cover plate can seal the installation hole where no drainage pipe is inserted, so that only one specification of base and well body needs to be produced, avoiding excessive mold 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, reduce labor costs, and facilitate later disassembly and recycling.

[0009] As needed, drainage pipes can be connected by connecting components to obtain drainage pipes of different lengths. When used in conjunction with the well body, drainage systems with different routes can be constructed in any combination. This high applicability means that only one specification of drainage pipe needs to be produced, eliminating the need to prefabricate different specifications of drainage pipes according to the area of ​​the construction site, thus avoiding excessive mold costs and further reducing costs.

[0010] Optionally, a second through hole is provided on the inner wall of the mounting hole away from the first through hole, and the second through hole is for the positioning rod to pass through.

[0011] By adopting the above technical solution, a second perforation is set, and the positioning rod is sequentially passed through the first perforation, the through hole, and the second perforation to achieve the positioning rod penetrating the drainage pipe, thereby improving the connection strength between the drainage pipe and the well body.

[0012] Optionally, the through holes are located at opposite ends of the drain pipe. The connecting assembly includes a first collar, two inserts disposed on the first collar, and a second collar detachably connected to the first collar. The first collar and the second collar are joined to form a clearance hole for the drain pipe to pass through. The two inserts are distributed along the length of the drain pipe, and the through holes allow the inserts to pass through.

[0013] By adopting the above technical solution, when it is necessary to connect adjacent drain pipes, the two inserts on the first collar are respectively inserted into the through holes on the two adjacent drain pipes, and then the second collar is connected to the first collar. The second collar abuts against the drain pipe to limit the first collar, and the inserts abut against the inner wall of the through hole to realize the connection between the two adjacent drain pipes.

[0014] Optionally, the first collar is provided with a sliding groove, and the second collar is provided with a slider. The sliding groove allows the slider to slide and engage along the length of the drain pipe.

[0015] By adopting the above technical solution, setting a slide groove and a slider, the slider can be moved into the slide groove or moved out of the slide groove to achieve a detachable connection between collar one and collar two, making it more convenient to connect collar one and collar two and to remove collar two from collar one.

[0016] Optionally, a filling groove is provided on the outer side wall of the first collar. The filling groove is located at the end of the first collar and extends through the first collar in a direction close to the second collar. A filling groove is provided on the outer side wall of the second collar. The filling groove is located at the end of the second collar and extends through the second collar in a direction close to the first collar. When the slider is inserted into the groove, the first filling groove and the second filling groove are aligned.

[0017] By adopting the above technical solution and setting up filling groove one and filling groove two, when the adjacent drainage pipes are connected and the soil is backfilled, the soil will fill filling groove one and filling groove two, thereby inhibiting the relative displacement between collar one and collar two. As time goes by, the soil will gradually settle and compact, and the resistance to the relative displacement between collar one and collar two will become greater and greater, further inhibiting the movement between collar one and collar two and improving the stability of the connection between adjacent drainage pipes.

[0018] Optionally, a protruding ring is provided on the outer side wall of the main body, the protruding ring is arranged around the outer periphery of the mounting hole, and a sealing ring is provided on the drain pipe. When the positioning rod is inserted into the through hole, the sealing ring abuts against the protruding ring. When the insert block is inserted into the through hole, the sealing ring abuts against the first collar and the second collar.

[0019] By adopting the above technical solution, a convex ring is set to improve the structural strength of the connection between the well body and the drainage pipe, and a sealing ring is set to improve the sealing performance of the connection between the well body and the drainage pipe, as well as between adjacent drainage pipes.

[0020] Optionally, the cover plate includes a plate body and a snap-fit ​​portion provided on the plate body. The plate body has a receiving groove for the convex ring to snap into. The snap-fit ​​portion is located in the receiving groove. The positioning hole is provided on the snap-fit ​​portion. The mounting hole and the water passage hole are both for the snap-fit ​​portion to snap into. When the snap-fit ​​portion snaps into the water passage hole, the snap-fit ​​portion fits against the inner wall of the water passage hole and is rotatably connected to the drain pipe.

[0021] By adopting the above technical solution, during construction, after the drainage pipe is installed on the well body, the locking part can be inserted into the end of the water passage hole away from the well body, and the plate body can be rotated to make the positioning hole and the through hole misaligned, thereby blocking the drainage pipe. This can reduce the possibility of sewage or debris entering the construction area through the well body and drainage pipe, thus affecting the construction process. When connecting the drainage pipe later, the cover plate can be removed. It is convenient to use local materials and operate easily.

[0022] Optionally, a limiting block is provided on the inner wall of the water passage hole, and a first slot is provided on the outer wall of the snap-in part. The first slot penetrates the snap-in part in a direction away from the plate body. A second slot is provided on the inner wall of the first slot. The second slot is located on the side of the first slot along the rotation direction of the snap-in part. Both the first slot and the second slot are for the limiting block to snap into. When the limiting block is snapped into the second slot, the positioning hole and the through hole are misaligned.

[0023] By adopting the above technical solution, when the locking part is inserted into the water passage hole, the limiting block is inserted into the first slot. Then, the plate body is rotated to drive the locking part to rotate, so that the limiting block is inserted into the second slot. When water or debris impacts the locking part, the limiting block abuts against the inner wall of the second slot to limit the locking part, reducing the situation where the cover plate is impacted and falls off the drain pipe.

[0024] Optionally, the insert portion has a cavity, and when the limiting block is inserted into the second slot, the cavity is located above the axis of the insert portion.

[0025] By adopting the above technical solution, the center of gravity of the cover plate is changed by setting a cavity, so that the limiting block remains in the second slot when the cover plate blocks the drain pipe.

[0026] Secondly, this application provides a construction method, which adopts the following technical solution:

[0027] A construction method for a municipal road drainage construction structure as described above includes the following steps:

[0028] S1. First, the base is fixed to the foundation by anchoring, and then a waterproof coating is applied inside the base to cover the anchor rod.

[0029] S2. Insert each drain pipe into the installation hole and align the first through hole with the through hole. If necessary, insert the cover plate into the remaining installation holes so that the first through hole is aligned with the positioning hole. Then move the well body, each drain pipe, and the cover plate so that the positioning rod passes through each first through hole to complete the installation of the drain pipe and the cover plate.

[0030] S3. If the drain pipe is not long enough, connect adjacent drain pipes using a connecting assembly;

[0031] S4. Apply a waterproof coating to the inner and outer walls of the well body, backfill with soil, and form a roadbed.

[0032] By adopting the above technical solutions, 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.

[0033] In summary, this application includes at least one of the following beneficial technical effects:

[0034] 1. 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 easy to disassemble and recycle later. As needed, the drainage pipe can be connected by connecting components to obtain "drainage pipes" of different lengths. When used in conjunction with the well body, drainage systems with different routes can be constructed in any combination. It has high applicability and helps to further reduce costs.

[0035] 2. When it is necessary to connect adjacent drain pipes, insert the two inserts on collar one into the through holes on the two adjacent drain pipes respectively, and then attach collar two to collar one. This will achieve the connection between the two adjacent drain pipes. By setting filling groove one and filling groove two, the movement between collar one and collar two is suppressed, which improves the stability of the connection between adjacent drain pipes.

[0036] 3. During construction, the locking part can be inserted into the end of the water passage hole away from the well body, and the plate body can be rotated to make the positioning hole and the through hole misaligned, thereby blocking the drainage pipe. This can reduce the possibility of sewage or debris entering the construction area through the well body and drainage pipe, thus affecting the construction process. When connecting the drainage pipe later, the cover plate can be removed. It is easy to use local materials and operate. Attached Figure Description

[0046] The following is in conjunction with the appendix Figures 1-8 This application will be described in further detail.

[0047] This application discloses a municipal road drainage construction structure. See also... Figure 1 and Figure 2 The municipal road drainage construction structure includes a well body 1 and a drainage pipe 2. The well body 1 includes a base 11, a main body 12, a cover plate 13, and a connecting component 14. The base 11 is rectangular and has several positioning rods 3 fixed on it. The positioning rods 3 are all located above the base 11 and are vertically arranged. The positioning rods 3 correspond to each side of the base 11. The upper end face of the main body 12 has an inlet 121 that vertically penetrates the main body 12. The outer side wall of the main body 12 has several mounting holes 122. The number and position of the mounting holes 122 correspond to the number and position of the positioning rods 3. The mounting holes 122 are located on each side of the main body 12 and are connected to the inlet 121. The drainage pipe 2 is inserted into the mounting holes 122.

[0048] See Figure 1 and Figure 2The bottom wall of the main body 12 is also provided with through holes 123. The number and position of through holes 123 correspond one-to-one with the number and position of mounting holes 122. Each through hole 123 is connected to the corresponding mounting hole 122. Each mounting hole 122 is provided with through holes 124 on the inner wall away from through holes 123. Both through holes 123 and through holes 124 are for the positioning rod 3 to pass through.

[0049] See Figure 1 and Figure 3 A water passage hole 21 is provided on the end face of the drain pipe 2. The water passage hole 21 passes through the drain pipe 2 along the length direction of the drain pipe 2. Two through holes 22 are provided on the outer side wall of the drain pipe 2. The two through holes 22 are located at opposite ends of the drain pipe 2 respectively. The through holes 22 pass through the drain pipe 2 in a direction perpendicular to the length direction of the drain pipe 2. The through holes 22 and the water passage hole 21 are connected. The through holes 22 allow the positioning rod 3 to pass through.

[0050] See Figures 2-5 The connecting component 14 is used to connect adjacent drain pipes 2. The connecting component 14 includes a first collar 141, a second collar 142, and two inserts 143. The first collar 141 and the second collar 142 are spliced ​​to form a clearance hole 4, through which the drain pipe 2 passes. When the drain pipe 2 passes through the clearance hole 4, the outer wall of the drain pipe 2 fits against the inner wall of the clearance hole 4. Sliding grooves 1411 are provided on the two opposite end faces of the first collar 141. The same end of the two sliding grooves 1411 passes through the first collar 141. A slider is fixed on the second collar 142. 5. The number and position of the sliders 5 correspond one-to-one with the number and position of the grooves 1411. The grooves 1411 allow the corresponding sliders 5 to slide and engage along the length of the drain pipe 2. The first collar 141 and the second collar 142 are detachably connected through the sliding engagement between the sliders 5 and the grooves 1411. In this embodiment, the slider 5 is a dovetail block, and the groove 1411 is a dovetail groove that engages with the slider 5. The two inserts 143 are both located in the clearance hole 4 and are spaced apart along the length of the drain pipe 2. The through hole 22 allows the inserts 143 to pass through.

[0051] In practical use, when it is necessary to connect adjacent drain pipes 2, the two inserts 143 on collar one 141 are respectively inserted into the through holes 22 on the two adjacent drain pipes 2, and then the slider 5 on collar two 142 is slid and inserted into the corresponding groove 1411 on collar one 141 to realize the connection between collar one 141 and collar two 142. The collar one 141 is limited by the collar two 142 abutting against the drain pipe 2, and the connection between the two adjacent drain pipes 2 is realized by the inserts 143 abutting against the inner wall of the through hole 22.

[0052] See Figure 4Two filling grooves 1412 are provided on the outer wall of collar 141. Both filling grooves 1412 are located on the side of collar 141 away from collar 2 142 and are located at opposite ends of collar 141. Filling grooves 1412 penetrate collar 141 in the direction closer to collar 2 142. Two filling grooves 2 1421 are provided on the outer wall of collar 2 142. Both filling grooves 2 1421 are located on the side of collar 2 142 away from collar 141 and are located at opposite ends of collar 2 142. Filling grooves 2 1421 penetrate collar 2 142 in the direction closer to collar 141. When slider 5 is inserted into slide groove 1411 and abuts against the inner wall of slide groove 1411, filling grooves 1412 and filling grooves 2 1421 are aligned.

[0053] In actual use, after the adjacent drainage pipes 2 are connected and backfilled, the soil will fill the filling groove 1412 and filling groove 2 1421, thereby suppressing the relative displacement between the collar 141 and the collar 2 142 and improving the stability of the connection between adjacent drainage pipes 2.

[0054] See Figures 1-4 A protruding ring 6 is fixed on the outer wall of the main body 12. The number and position of the protruding ring 6 correspond one-to-one with the number and position of the mounting holes 122. Each protruding 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. The number and position of the sealing ring 7 correspond one-to-one with 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 outside of the drain pipe 2. When the positioning rod 3 is inserted into the through hole 22, the sealing ring 7 abuts against the protruding ring 6. When the insert block 143 is inserted into the through hole 22, the two sealing rings 7 on the two adjacent drain pipes 2 that are close to each other abut against the first collar 141 and the second collar 142. By setting the protruding ring 6, the structural strength of the connection between the well body 1 and the drain pipe 2 is improved. By setting the sealing ring 7, the sealing performance of the connection between the well body 1 and the drain pipe 2 and between adjacent drain pipes 2 is improved. In this embodiment, the material of the sealing ring 7 is rubber.

[0055] It should be noted 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 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, causing the slider 5 to be unable to move.

[0056] See Figure 3 and Figure 6The cover plate 13 includes a plate body 131 and a snap-fit ​​part 132. A receiving groove 1311 is provided on the plate body 131 for the protruding ring 6 to snap into. The snap-fit ​​part 132 is located within the receiving groove 1311 and is fixedly connected to the plate body 131. Both the water passage hole 21 and the mounting hole 122 are for the snap-fit ​​part 132 to snap into. When the snap-fit ​​part 132 is snapped into the water passage hole 21, the snap-fit ​​part 132 fits against the inner wall of the water passage hole 21 and is rotatably connected to the drain pipe 2. The rotation axis of the drain pipe 2 is parallel to the length direction of the drain pipe 2. When the locking part 132 is locked into the mounting hole 122, the convex ring 6 is locked into the receiving groove 1311. The convex ring 6 abuts against the inner peripheral wall of the receiving groove 1311, thereby limiting the locking part 132. A positioning hole 1321 is provided on the outer side wall of the locking part 132. The positioning hole 1321 penetrates the locking part 132 radially and allows the positioning rod 3 to pass through.

[0057] See Figures 2-8 Limiting blocks 8 are fixed on the inner wall of the water passage 21. The number and position of the limiting blocks 8 correspond one-to-one with the number and position of the through holes 22. The two limiting blocks 8 are located at opposite ends of the water passage 21 and on opposite sides of the water passage 21. A first slot 1322 is provided on the outer wall of the locking part 132. The first slot 1322 penetrates the locking part 132 in a direction away from the plate 131. A second slot 1323 is provided on the inner wall of the first slot 1322. 23 is located on one side of the slot 1322 along the rotation direction of the insertion part 132, and both slot 1322 and slot 23 are for the limiting block 8 to be inserted. A cavity 9 is also provided in the insertion part 132. When the limiting block 8 is inserted into slot 2323, the positioning hole 1321 and the through hole 22 are offset, and the cavity 9 is located above the axis of the insertion part 132. By setting the cavity 9, the center of gravity of the cover plate 13 is changed, so that the limiting block 8 is kept in the slot 2323.

[0058] In actual use, during construction, after the drainage pipe 2 is installed on the well body 1, the locking part 132 can be inserted into the end of the water passage hole 21 away from the well body 1, so that the limiting block 8 is inserted into the first slot 1322. Then, the plate body 131 is rotated to drive the locking part 132 to rotate, so that the limiting block 8 is inserted into the second slot 1323. At this time, the positioning hole 1321 and the through hole 22 are misaligned, thereby blocking the drainage pipe 2. This can reduce the situation where sewage or debris enters the construction area through the well body 1 and the drainage pipe 2, thus affecting the construction. When connecting the drainage pipe 2 later, the cover plate 13 can be removed. It is convenient to use local materials and operate.

[0059] The implementation principle of a municipal road drainage construction structure according to an embodiment of this application is as follows:

[0060] When building a drainage well, first install the base 11, then insert each drainage pipe 2 into the mounting hole 122 so that the through hole 22 and the through hole 123 are aligned. 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, thus completing the connection between the drainage pipe 2 and the well body 1.

[0061] When the drainage well is selected as a one-way, two-way, or three-way connection (i.e., the drainage well is connected to only one, two, or three drainage pipes 2), the locking part 132 is inserted into the mounting hole 122, so that the positioning hole 1321 and the through hole 123 are aligned. While the positioning rod 3 passes through the through hole 123 and the through hole 22, the other positioning rods 3 pass through the through hole 123 and the positioning hole 1321 to position the cover plate 13. The cover plate 13 can block the mounting hole 122 where the drainage pipe 2 is not inserted, so that the base 11 and the well body 1 only need to be produced in one specification, avoiding excessive mold opening costs. The well body 1, drainage pipe 2, base 11 and 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.

[0062] As needed, the drainage pipe 2 can be connected by the connecting component 14 to obtain drainage pipes 2 of different lengths. When used in conjunction with the well body 1, drainage systems with different routes can be constructed in any combination. This makes the system highly adaptable, and only one specification of drainage pipe 2 needs to be produced. There is no need to prefabricate different specifications of drainage pipe 2 according to the area of ​​the construction area, which avoids excessive mold opening costs and helps to further reduce costs.

[0063] This application also discloses a construction method for a municipal road drainage construction structure as described above, including the following steps:

[0064] S1. First, fix the base 11 to the foundation by anchoring, and then coat the inside of the base 11 with a waterproof coating that covers the anchor rod;

[0065] S2. Insert each drain pipe 2 into the mounting hole 122 and align the through hole 123 with the through hole 22. As needed, insert the cover plate 13 into the remaining mounting holes 122 so that the through hole 123 is aligned with the positioning hole 1321. Then move the well body 1, each drain pipe 2, and the cover plate 13 so that the positioning rod 3 passes through each through hole 123, thus completing the installation of the drain pipe 2 and the cover plate 13.

[0066] S3. If the length of drain pipe 2 is insufficient, connect adjacent drain pipes 2 through connecting component 14;

[0067] S4. Apply a waterproof coating to the inner and outer walls of well body 1, and backfill with soil to form a roadbed.

[0068] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
