Description

Technical Field

[0001] This invention relates to the field of building construction, and in particular to a sewage well with an anti-settlement structure and a construction method thereof. Background Technology

[0002] Drainage pipes are commonly used to transport sewage or rainwater. As an important part of the urban drainage system, drainage pipes need to be inspected or cleaned. Therefore, sewage inspection wells or rainwater inspection wells need to be installed above the drainage pipes to facilitate the maintenance or cleaning work of the drainage pipes by the staff.

[0003] Sewage wells or rainwater wells are often installed on roads or inside residential areas for inspection purposes. These areas have high traffic or pedestrian flow. The well covers are subjected to long-term pressure from vehicles or people walking on them. In addition, due to changes in environmental and climatic conditions, the support for the well body and the well cover is relatively simple. As a result, the well cover and the well body are prone to sinking together. After the well body sinks, it will create a height difference with the road surface and may cause the surrounding road surface to sink. Summary of the Invention

[0004] In order to increase the anti-settlement structure and slow down the settlement of the manhole cover and manhole body, this application provides a sewage well with an anti-settlement structure and a construction method thereof.

[0005] Firstly, this application provides a sewage well with an anti-settlement structure, employing the following technical solution:

[0006] A sewage well with anti-settlement structure includes a well body, a well cover, a well base, and a base. The well base includes an upper well base and a lower well base. The well cover is detachably connected to the upper well base. The well cover has several air holes along its circumference. The base includes an upper base and a lower base. A sewage pipe is provided between the upper base and the lower base. The upper and lower ends of the well body are respectively connected to the lower well base and the upper base. The well body is provided with several anti-settlement structures. The well body has several cavities for placing the anti-settlement structures. The anti-settlement structures are located in corresponding cavities. The well body is provided with driving components that correspond one-to-one with the anti-settlement structures. The anti-settlement structures are driven by the corresponding driving components.

[0007] By adopting the above technical solution, the well body is installed in layers, and each layer of the well body is equipped with an anti-settlement structure. The driving component is used to drive the corresponding anti-settlement structure. The anti-settlement structure is set along the height direction of the well body, so that the parts of the well body at different heights are connected to the external base layer. The anti-settlement structure provides vertical support for the corresponding well body, reducing the settlement of the well body, which in turn helps to slow down the settlement of the well cover and well body, and reduces damage to the road surface.

[0008] Optionally, the anti-settlement structure includes a geared disc, several first gears, and a limiting rod. The geared disc is rotatably connected to the well body, and the limiting rod is slidably connected to the well body. The first gears are all vertically arranged and rotatably connected to the well body. The first gears are all meshed with the geared disc. Each first gear is fixedly connected with a threaded rod. The threaded rod passes through the limiting rod and is threadedly connected to the limiting rod. The end of the limiting rod away from the threaded rod is tapered.

[0009] By adopting the above technical solution, the rotation of the gear disk drives the first gear to rotate, which causes the threaded rod to rotate. The well body limits the limit rod, causing the limit rod to move along the length of the threaded rod. The end of the limit rod away from the threaded rod is inserted into the bottom base outside the well body, so that the bottom base provides vertical limitation for the well body through the limit rod, thereby slowing down the settlement of the well body and the well casing.

[0010] Optionally, the driving component includes a driving rod, a second gear, and a driving gear. Several hollow sleeves are fixedly connected to the well body. The driving rod passes through the sleeves and its lower end is fixedly connected to the driving gear. The second gear is fixedly connected to the outer edge of the gear disk and can mesh with the driving gear.

[0011] By adopting the above technical solution, the drive rod is inserted into the sleeve from top to bottom, so that the drive gear meshes with the second gear. Rotating the drive rod causes the drive gear to drive the second gear to rotate, which in turn drives the gear disk to rotate, thus completing the drive of the anti-settlement structure.

[0012] Optionally, the sleeve is provided with a limiting component, which includes two arc-shaped plates and two elastic components. The two ends of the elastic components are fixedly connected to the inner wall of the sleeve and the corresponding arc-shaped plates, respectively. When the elastic components are in a compressed state, the distance between the two arc-shaped plates is greater than the diameter of the drive gear. A cone tip is fixedly connected to the lower end face of the drive gear.

[0013] By adopting the above technical solution, the cone tip pushes the two arc-shaped plates away from each other, increasing the distance between the arc-shaped plates and making it easier for the drive gear to pass through. When the drive gear separates from the arc-shaped plates, the arc-shaped plates are reset under the action of the elastic element and abut against the drive rod, completing the clamping of the sleeve on the limit rod, ensuring that the drive rod is placed vertically, thereby ensuring the meshing effect of the drive gear and the second gear.

[0014] Optionally, the upper end of the manhole cover is provided with an opening component, which includes a folding rod. The folding rod is rotatably connected to the upper surface of the manhole cover. A hook is rotatably connected to the free end of the folding rod. A ring is fixedly connected to the end of the hook. A fixing component is rotatably connected to the manhole cover. An arc-shaped pointed hook is provided at the lower end of the fixing component. The manhole cover has a through hole for the hook to pass through.

[0015] By adopting the above technical solution, after the folding rod is unfolded, the hook passes through the through hole and abuts against the lower end face of the manhole cover. By rotating the fixing part, the arc-shaped hook passes through the ring, and the fixing part fixes the hook, so that the free end of the folding rod is fixed to the manhole cover, and the middle part of the folding rod stands up to facilitate the workers to open the manhole cover.

[0016] Optionally, a buffer component is provided between the upper well seat and the lower well seat. The buffer component is a spring damper, and the two ends of the spring damper are fixedly connected to the upper well seat and the lower well seat, respectively.

[0017] By adopting the above technical solution, when the manhole cover is subjected to pressure, the upper manhole seat provides support for the manhole cover, while the spring damper absorbs the impact force, reducing the impact on the manhole cover and the manhole seat, and resets when the pressure is removed, which helps to reduce damage to the manhole body and the road surface.

[0018] Optionally, the upper well seat is fixedly connected to two limiting plates, and the well cover is provided with a limiting groove that matches the limiting plates.

[0019] By adopting the above technical solution, after the manhole cover is installed vertically, the manhole cover is rotated so that the two limiting plates enter the corresponding limiting grooves respectively. The limiting grooves limit the limiting plates, improve the connection stability between the upper manhole seat and the manhole cover, and reduce the possibility of the manhole cover loosening or flying off.

[0020] Secondly, this application also provides a construction method for a sewage well with an anti-settlement structure, employing the following technical solution:

[0021] S1: Install the base, build the lower base and the bottom layer with concrete, install the sewage pipe and the upper base, and install the sewage pipe between the upper base and the lower base.

[0022] S2: Install the well body. The well body is constructed in layers. After the well body is fixed, install the corresponding driving components to complete the construction of the base layer at the height of the well body layer. The driving components drive the corresponding anti-settlement structure to complete the installation of the anti-settlement structure.

[0023] S3: Install the well base, construct concrete masonry between the lower well base and the upper part of the well body, install the upper well base, and complete the base construction;

[0024] S4: Install the manhole cover and connect it to the upper manhole base.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. By setting up an anti-settlement structure, the manhole body can receive support from the surrounding subbase at different heights, which helps to slow down the settlement of the manhole cover and the manhole body, while reducing damage to the road surface;

[0027] 2. By setting an opening mechanism, the folding rod provides a support point for opening the manhole cover, making it easier for workers to lift or perform other operations on the manhole cover;

[0028] 3. By setting up buffer components, the buffer components absorb the impact received by the manhole cover, reducing the impact on the manhole cover and the manhole body, thereby reducing damage to the manhole body and the road surface. Attached Figure Description

Detailed Implementation

[0034] The present application will be further described in detail below with reference to all the accompanying drawings.

[0035] This application discloses a sewage well with an anti-settlement structure. Example

[0036] Reference Figure 1 A sewage well with an anti-settlement structure includes a well body 1, a well cover 2, a well base 3, and a base 4. The base 4 includes an upper base 41 and a lower base 42. A sewage pipe 5 is provided between the upper base 41 and the lower base 42. After the workers build the lower base 42 and the bottom layer, they fix the sewage pipe 5 to the lower base 42 and then install the upper base 41, so that the upper base 41 is fixed to the sewage pipe 5 and the lower base 42.

[0037] Reference Figure 1 and Figure 2The well body 1 is divided into several parts along the height direction. In this embodiment, the well body 1 is divided into three parts: upper, middle and lower. The well body 1 is provided with several anti-settlement structures 6. Each anti-settlement structure 6 corresponds to one part of the well body 1. The well body 1 has several cavities for placing the anti-settlement structures 6. The cavities are located at the lower end of each part of the well body 1, and the anti-settlement structures 6 are located in the corresponding cavities.

[0038] Reference Figure 1 and Figure 2 The well body 1 is equipped with driving components 7 corresponding to the anti-settlement structures 6. Each anti-settlement structure 6 is driven by a corresponding driving component 7. The well body 1 has several grooves for pouring concrete to improve the strength of the well body 1. The driving components 7 are located in the wall thickness of the well body 1 and between two adjacent grooves. After the workers install the upper base 41, they construct the lower part of the well body 1 and the upper base 41 with concrete, then install the corresponding driving components 7. After completing the construction of the base layer of this part of the well body 1, the driving components 7 are used to complete the installation of the anti-settlement structures 6.

[0039] Reference Figure 1 and Figure 2 The anti-settlement structure 6 includes a gear disc 61, several first gears 62 and a limiting rod 63. The gear disc 61 is rotatably connected to the well body 1. The driving component 7 drives the gear disc 61 to rotate. The first gears 62 are all vertically arranged and rotatably connected to the well body 1. The first gears 62 are all meshed with the gear disc 61. The gear disc 61 drives the first gears 62 to rotate. The first gears 62 are all fixedly connected with threaded rods 64. The threaded rods 64 rotate with the first gears 62.

[0040] Reference Figure 1 and Figure 2 The threaded rod 64 passes through and is threadedly connected to the limiting rod 63. The limiting rod 63 is slidably connected to the well body 1. The limiting rod 63 is fixedly connected to the limiting strip. The well body 1 has a sliding groove that matches the limiting strip. The sliding groove limits the limiting strip, so that when the threaded rod 64 rotates, the limiting rod 63 moves along the length of the threaded rod 64. The end of the limiting rod 63 away from the threaded rod 64 is tapered, and the tapered tip of the limiting rod 63 is inserted into the base layer around the well body 1.

[0041] Reference Figure 1 and Figure 2The driving component 7 includes a driving rod 71, a second gear 72, and a driving gear 73. Several hollow sleeves 74 are fixedly connected to the well body 1. The driving rod 71 passes through a sleeve 74 and its lower end is fixedly connected to the driving gear 73. The worker inserts the driving rod 71 into the sleeve 74 with the end connected to the driving gear 73 facing downwards. The second gear 72 is fixedly connected to the outer edge of the gear disc 61 and can mesh with the driving gear 73. The driving rod 71 is inserted downwards into the sleeve 74, and the driving gear 73 meshes downwards with the second gear 72. The worker rotates the driving rod 71, causing the driving gear 73 to rotate, which in turn causes the second gear 72 to rotate, thus rotating the gear disc 61.

[0042] Reference Figure 1 and Figure 2 The sleeve 74 is equipped with a limiting component, which includes two arc-shaped plates 751 and two elastic components. The elastic components are springs or elastic blocks that can deform. The two ends of the elastic components are fixedly connected to the inner wall of the sleeve 74 and the corresponding arc-shaped plates 751, respectively. A cone tip is fixedly connected to the lower end face of the drive gear 73. When the drive rod 71 and the drive gear 73 are inserted into the sleeve 74, the cone tip first contacts the two arc-shaped plates 751, so that the two arc-shaped plates 751 move away from each other. When the elastic component is in a compressed state, the distance between the two arc-shaped plates 751 is greater than the diameter of the drive gear 73, which facilitates the entry of the drive gear 73.

[0043] Reference Figure 1 and Figure 2 When the drive gear 73 moves downwards and separates from the sleeve 74, the two arc-shaped plates 751 approach each other under the elastic force of the elastic element. The concave surfaces of the two arc-shaped plates 751 abut against the drive rod 71, clamping the drive rod 71 and keeping it vertical, which facilitates the meshing of the drive gear 73 and the second gear 72. The rotation of the drive rod 71 drives the gear disk 61 to rotate, which in turn causes the limiting rod 63 to insert into the base layer around the well body 1. The base layer provides vertical support for the limiting rod 63, thereby providing vertical support for the well body 1, which helps to slow down the settlement of the well body 1.

[0044] Reference Figure 1 and Figure 2 After the lower part of the well body 1 and the anti-settlement structure 6 are installed, the middle part of the well body 1 is placed above the lower part of the well body 1 and the two are fixed. Then, the corresponding drive components 7 are installed. After the construction of the base layer at the height of the middle part of the well body 1 is completed, the above process is repeated. The installation of the upper part of the well body 1 and the corresponding anti-settlement structure 6 are installed in the same way as described above.

[0045] Reference Figure 1 and Figure 2The well base 3 includes an upper well base 31 and a lower well base 32. Workers construct the lower well base 32 with concrete and the upper part of the well body 1 so that the upper and lower ends of the well body 1 are connected to the lower well base 32 and the upper base 41 respectively. A buffer 311 is provided between the upper well base 31 and the lower well base 32. The buffer 311 is a spring damper. The two ends of the spring damper are fixedly connected to the upper well base 31 and the lower well base 32 respectively. After the workers connect the spring damper to the lower well base 32, they construct the upper well base 31 and the lower well base 32 with concrete and the upper end of the spring damper is connected to the upper well base 31.

[0046] Reference Figure 1 and Figure 3 The manhole cover 2 has several vent holes along its circumference. Since sewage flowing into the manhole can easily generate gas, these vent holes are used to release gas and prevent the accumulation of gas inside the manhole cover 2 from causing an explosion. The manhole cover 2 is detachably connected to the upper manhole seat 31. The upper manhole seat 31 is fixedly connected to two limiting plates 312. The manhole cover 2 has limiting grooves 21 that fit the limiting plates 312. The two limiting plates 312 are positioned opposite each other. When the manhole cover 2 is inserted downwards between the two limiting plates 312 and rotated, the two limiting plates 312 are inserted into the limiting grooves 21. The limiting grooves 21 limit the limiting plates 312, increasing the connection stability between the manhole cover 2 and the upper manhole seat 31, while reducing the possibility of the manhole cover 2 loosening or flying off.

[0047] Reference Figure 1 and Figure 4 The diameter of the manhole cover 2 is larger than that of the upper manhole seat 31, which transmits part of the pressure on the manhole cover 2 to the surrounding ground, further reducing the settlement of the manhole cover 2 and the manhole body. The upper end of the manhole cover 2 is provided with an opening part 8, which provides a support point, making it easy for workers to open the manhole cover 2 for pipeline maintenance. The opening part 8 includes a folding rod 81, which is rotatably connected to the upper end face of the manhole cover 2. The upper end face of the manhole cover 2 is provided with a placement groove that matches the folding rod 81, ensuring that the upper surface of the manhole cover 2 is flat when the folding rod 81 is retracted.

[0048] Reference Figure 1 and Figure 4 The free end of the folding rod 81 is rotatably connected to a hook 82, and the end of the hook 82 is fixedly connected to a ring 83. The manhole cover 2 has a through hole for the hook 82 to pass through. After the worker unfolds the folding rod 81, the hook 82 passes through the through hole as a whole, and the ring 83 abuts against the lower end face of the manhole cover 2. The manhole cover 2 is rotatably connected to a fixing member 84. The lower end of the fixing member 84 is provided with an arc-shaped hook 85. Then, the fixing member 84 is rotated so that the arc-shaped hook 85 passes through the ring 83, and the hook 82 is fixed below the through hole. The worker can open the manhole cover 2 by directly pulling or lifting the folding rod 81.

[0049] The implementation principle of a sewage well with an anti-settlement structure in this application embodiment is as follows: by setting multiple anti-settlement structures 6, all the limiting rods 63 are inserted into the surrounding subbase. The subbase provides vertical support for the limiting rods 63, thereby providing vertical support for the well body 1, which helps to slow down the settlement of the well body 1 and reduce damage to the surrounding road surface.

[0050] This application also discloses a construction method for a sewage well with an anti-settlement structure, employing the following technical solution.

[0051] A construction method for a sewage well with an anti-settlement structure includes the following steps:

[0052] S1: Install base 4, build concrete between lower base 42 and bottom layer, install sewage pipe 5 and upper base 41, so that sewage pipe 5 is installed between upper base 41 and lower base 42.

[0053] S2: Install well body 1. Well body 1 is constructed in layers. After well body 1 is fixed, install the corresponding driving component 7 to complete the construction of the base layer of well body 1 at that height. The driving component 7 drives the corresponding anti-settlement structure 6 to work, and completes the installation of the anti-settlement structure 6.

[0054] S3: Install well base 3, construct concrete masonry between the lower well base 32 and the upper end of the well body 1, install the upper well base 31, and complete the base construction;

[0055] S4: Install manhole cover 2 and connect manhole cover 2 to upper manhole seat 31.

[0056] 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.
