Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of drainage pipes, in particular to an inspection well pipe connection structure. Background Art
[0002] Inspection wells are designed for easy maintenance of urban underground infrastructure, including power supply, water supply, drainage, sewage, communications, cable TV, gas pipes, and streetlight lines. They are typically located at pipeline intersections, bends, changes in pipe diameter or slope, and at regular intervals along straight pipe sections to facilitate regular inspection of ancillary structures.
[0003] When connecting the inspection well with the pipes on both sides, the newly built pipe is generally inserted into the inspection well and then connected through cement mortar. Since the concrete well foundation needs to be poured in advance at the bottom when the inspection well is built, the pipe is placed on the side above the concrete well foundation. At the position where the pipe is separated from the concrete well foundation, the pipe is suspended or filled with soil underneath. During long-term use, the soil gradually sinks. At this time, there is no support under the pipe at this position, and it is easy to be suspended, which can easily cause deformation and damage to the pipe. Therefore, a inspection well pipe connection structure is proposed to address the above problems. Utility Model Content
[0004] The purpose of the utility model is to provide a manhole pipe connection structure to solve the problems raised in the above background technology.
[0005] To achieve the above objectives, the present invention provides the following technical solutions:
[0006] As an optional solution of the inspection well pipe connection structure described in the utility model, wherein: an inspection well pipe connection structure includes a concrete well foundation, a well body and a soil layer,
[0007] A well body is fixedly connected to the top of the concrete well foundation, connecting pipes are fixedly connected to both sides of the well body, and fixing rings are provided on the outside of the connecting pipes, and a sealing ring is fixedly connected to one side of the fixing rings. Fixing screws arranged in a circular trajectory are installed on the outside of the fixing rings, and the fixing screws pass through the fixing rings and are connected to the connecting pipes;
[0008] A support assembly is provided below the connecting pipe, and the support assembly is provided below the soil layer;
[0009] The support assembly includes a rotating handle, a threaded shaft and a threaded sleeve. The two sides of the rotating handle are fixedly connected to the threaded shaft. The outer side of the threaded shaft is spirally connected to the threaded sleeve. The other end of the lower threaded sleeve is fixedly connected to the lower pressure cover, and the other end of the upper threaded sleeve is fixedly connected to the top cover.
[0010] When connecting the inspection well to the pipes on both sides, the newly built pipe is generally inserted into the inspection well and then connected through cement mortar. Since the concrete well foundation needs to be poured in advance at the bottom during the construction of the inspection well, the pipe is placed on one side above the concrete well foundation. At the position where the pipe is separated from the concrete well foundation, the pipe is suspended or filled with soil underneath. During long-term use, the soil gradually sinks. At this time, there is no support under the pipe at this position, which is prone to suspension, which can easily cause pipe deformation and damage. When the present device is in use, a support assembly is provided under the connecting pipe on one side of the concrete well foundation. The rod inside the down-pressure cover is inserted into the soil, and then the arc surface of the top cover is in close contact with the bottom of the connecting pipe. By turning the handle, the threaded shafts on both sides are driven to rotate. Under the action of the threaded sleeve, the top cover is in contact with the connecting pipe, and the down-pressure cover stably squeezes the soil, which plays the purpose of supporting the connecting pipe and ensuring the overall stability of the connecting pipe. The rotation of the nut and the threaded sleeve are tightly fitted, which can ensure that the threaded shaft and the threaded sleeve are not easy to loosen, thereby ensuring the support effect of the connecting pipe.
[0011] Preferably, a well ring is fixedly connected to the top of the well body, and a well cover is installed inside the well ring.
[0012] Preferably, a finishing layer is applied to the inner wall of the well body above the connecting pipe.
[0013] A plastering layer is provided on the inner wall of the well body, so that water leakage is not likely to occur when the water flows, and the setting of the well cover makes it easy to open it and then inspect the interior.
[0014] Preferably, the outer threads of the threaded shafts on the upper and lower sides are arranged in opposite directions, and the outer sides of the threaded shafts are both spirally connected with nuts.
[0015] Preferably, the upper end surface of the top cover is arranged in an arc shape, and the top of the top cover is tightly fitted with the connecting pipe.
[0016] Preferably, the lower end surface of the downward pressure cover is arranged in an arc shape, and the bottom of the downward pressure cover is fixedly connected with evenly distributed insertion rods.
[0017] When adjusting the top cover and the top cover, the threaded shafts on both sides of the handle are rotated. Since the threads on the outer sides of the threaded shafts are arranged in opposite directions, when the handle is rotated, the threaded sleeves on both sides can be moved up and down synchronously.
[0018] Compared with the prior art, the beneficial effects of the present invention are:
[0019] When the utility model is in use, a support assembly is provided under the connecting pipe on one side of the concrete well foundation, and the insertion rod inside the lower pressure cover is inserted into the soil, and then the arc surface of the top cover is in close contact with the bottom of the connecting pipe, and the threaded shafts on both sides are rotated by turning the rotating handle. Under the action of the threaded sleeve, the top cover is in contact with the connecting pipe, and the lower pressure cover stably squeezes the soil, thereby playing the role of supporting the connecting pipe and ensuring the overall stability of the connecting pipe. The rotation of the provided nut and the threaded sleeve tightly fit together, which can ensure that the threaded shaft and the threaded sleeve are not prone to loosening, thereby ensuring the supporting effect on the connecting pipe.
[0020] When the connecting pipe is connected to the well body, a sealing ring and a fixing ring are provided on the outside of the connecting pipe, and the fixing ring is embedded in the inside of the well body. At this time, the connecting pipe is not easy to slide under the action of the fixing ring. At the same time, the setting of the sealing ring can ensure that the connecting pipe and the well body are tightly connected to avoid water leakage. A finishing layer is provided on the inner wall of the well body. At this time, it is not easy for water to leak into the well body when the water flows. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0026] Example 1
[0027] See also Figure 1 、 Figure 2 and Figure 3, the utility model provides a technical solution:
[0028] A manhole pipe connection structure includes a concrete manhole foundation 1, a manhole body 2 and a soil layer 3.
[0029] A well body 2 is fixedly connected to the top of the concrete well foundation 1. Connecting pipes 5 are fixedly connected to both sides of the well body 2. A fixing ring 7 is provided on the outside of the connecting pipes 5. A sealing ring 9 is fixedly connected to one side of the fixing ring 7. A fixing screw 8 arranged in a circular trajectory is installed on the outside of the fixing ring 7. The fixing screw 8 passes through the fixing ring 7 and is connected to the connecting pipe 5.
[0030] A support assembly 6 is provided below the connecting pipe 5, and the support assembly 6 is provided below the soil layer 3;
[0031] The above-mentioned support assembly 6 includes a rotating handle 601, a threaded shaft 602 and a threaded sleeve 603. The two sides of the above-mentioned rotating handle 601 are fixedly connected with the threaded shaft 602. The outer side of the above-mentioned threaded shaft 602 is spirally connected with the threaded sleeve 603. The other end of the above-mentioned threaded sleeve 603 on the lower side is fixedly connected with the lower pressure cover 604, and the other end of the above-mentioned threaded sleeve 603 on the upper side is fixedly connected with the top cover 605.
[0032] When connecting the inspection well with the pipes on both sides, the newly built pipe is generally inserted into the inspection well, and then connected through cement mortar. Since the concrete well foundation needs to be poured in advance at the bottom when the inspection well is built, the pipe is placed on the side above the concrete well foundation. At the part where the pipe is separated from the concrete well foundation, the pipe is suspended or filled with soil underneath. During long-term use, the soil gradually sinks. At this time, there is no support under the pipe at this part, which is prone to suspension, which can easily cause deformation and damage to the pipe. When the device is in use, a support component 6 is provided under the connecting pipe 5 on one side of the concrete well foundation 1. , insert the insertion rod 606 inside the downward pressure cover 604 into the soil, and then the arc surface of the top cover 605 is in close contact with the bottom of the connecting pipe 5. By rotating the rotating handle 601, the threaded shafts 602 on both sides are driven to rotate. Under the action of the threaded sleeve 603, the top cover 605 is in contact with the connecting pipe 5. The downward pressure cover 604 stably squeezes the soil, which plays the role of supporting the connecting pipe 5 and ensuring the overall stability of the connecting pipe 5. The nut 607 is rotated and fits tightly with the threaded sleeve 603. At this time, it can be ensured that the threaded shaft 602 and the threaded sleeve 603 are not easy to loosen, ensuring the supporting effect of the connecting pipe 5;
[0033] In this embodiment, when the connecting pipe 5 is connected to the well body 2, a fixing ring 7 and a sealing ring 9 are provided on the outside of the connecting pipe 5, and the fixing ring 7 is embedded in the inside of the well body 2. At this time, the connecting pipe 5 is not easy to slide under the action of the fixing ring 7. At the same time, the setting of the sealing ring 9 can ensure that the connecting pipe 5 is tightly connected to the well body 2 to avoid water leakage.
[0034] Example 2
[0035] This embodiment is an improvement on embodiment 1. Figure 1 Specifically, a well ring 10 is fixedly connected to the top of the well body 2, and a well cover 11 is installed inside the well ring 10.
[0036] A finishing layer 4 is applied to the inner wall of the well body 2 above the connecting pipe 5 .
[0037] A plastering layer 4 is provided on the inner wall of the well body 2, which makes it difficult for water to leak from the well body 2 when the water flows, and the well cover 11 is convenient for opening it and then inspecting the interior;
[0038] In this embodiment, the finishing layer 4 is coated on the inner wall of the well body 2 with waterproof concrete, which serves a certain waterproofing purpose.
[0039] Example 3
[0040] This embodiment is an improvement on embodiment 2. Figure 3 Specifically, the outer threads of the threaded shaft 602 on the upper and lower sides are arranged in opposite directions, and the outer sides of the threaded shaft 602 are spirally connected with nuts 607.
[0041] The upper end surface of the top cover 605 is arranged in an arc shape, and the top of the top cover 605 is tightly fitted with the connecting pipe 5 .
[0042] The lower end surface of the downward pressure cover 604 is configured to be an arc surface, and the bottom of the downward pressure cover 604 is fixedly connected with evenly distributed insertion rods 606 .
[0043] When adjusting the top cover 605 and the top cover 605, the threaded shafts 602 on both sides of the handle 601 are rotated. Since the threads on the outer sides of the threaded shafts 602 are arranged in opposite directions, when the handle 601 is rotated, the threaded sleeves 603 on both sides can be moved up and down synchronously;
[0044] In this embodiment, the lower pressure cover 604 is inserted into the soil. At this time, due to the large contact area between the lower pressure cover 604 and the soil, the lower pressure cover 604 is not easy to sink, and the top cover 605 is in contact with a large area of the bottom of the connecting pipe 5, which effectively supports the connecting pipe 5. At the same time, the insertion rod 606 is stably inserted into the soil, and the lower pressure cover 604 can be further fixed at this time.
