Description
Technical Field
[0001] This invention relates to the field of wiring well technology, specifically to a contamination-proof composite resin wiring well structure and its implementation method. Background Technology
[0002] Cable manholes are outdoor connection devices that are widely used in cable integration and routing in large communication industries such as telecommunications, China Railcom, and China Netcom. Cable manholes are usually made of fiber-reinforced thermosetting composite materials with polyester resin as the matrix and are formed by pressing with manhole cover molds.
[0003] Chinese patent CN111980069A discloses a corrosion-resistant composite resin cable well. Two sets of screws are inserted into two sets of positioning grooves, and two sets of fixing grooves are inserted into the outer surfaces of the two sets of screws. A sealing cap is tightly attached to the upper end of the two fixing blocks. Fastening bolts are inserted into the upper part of the screws and tightly adhered to the sealing cap, thus securing the sealing cap within the connecting groove. This improves the sealing effect of the cable well, preventing water from entering and protecting the cable from damage, ensuring its normal operation.
[0004] In the aforementioned patent, when cables or pipes are inserted into the wiring well, the size of the pipe opening cannot be adapted to different specifications of pipe structures, which leads to gaps at the groove opening and easily causes water seepage and pollution. Therefore, it does not meet the existing needs. In response, a contamination-proof composite resin wiring well structure and its implementation method are proposed. Summary of the Invention
[0005] The purpose of this invention is to provide a contamination-proof composite resin conduit well structure and its implementation method. When installing pipes, a wide-mouth pipe clamp or a narrow-mouth pipe clamp can be selected according to the size, structure and quantity of the pipes, thereby ensuring the sealing of the pipe joint and solving the problems in the prior art.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a contamination-proof composite resin manhole structure, comprising a two-section manhole body and a manhole cover, and an elastic support disposed below the two-section manhole body. The two-section manhole body includes a through manhole and a transition manhole, with the through manhole disposed above the transition manhole. Expansion openings are provided around the perimeter of the transition manhole.

[0011] Preferably, the wide-mouth pipe sleeve is provided with a lubricating bead groove on the inner side, and a bearing bead is provided inside the lubricating bead groove. The narrow-mouth pipe sleeve is rotatably connected to the wide-mouth pipe sleeve through the bearing bead. The narrow-mouth pipe sleeve includes a first mating disc and a second mating disc, which are located on both sides of the bearing bead.
[0012] Preferably, the outer surfaces of both the first and second mating discs are provided with threaded inner grooves, and pipeline openings are provided around the threaded inner grooves.

[0014] Preferably, a pin is installed inside the threaded groove of the first concentric disc, and a sleeve is installed inside the threaded groove of the second concentric disc, wherein the sleeve and the pin are connected by an internal thread.
[0015] A method for implementing a contaminant-proof composite resin conduit manhole structure includes the following steps:
[0016] Step 1: Place the elastic support at the bottom of the shaft horizontally at the bottom of the tank and fix it inside the tank using the support bolts on its surface. After fixing, rotate the adjusting screw on the top of the elastic support to adjust the installation distance between the elastic support and the transfer shaft.
[0017] Step 2: Adjust the spacing to ensure that the height of the expansion pipe opening on the outside of the transfer shaft is consistent with the height of the pipe opening inside the trench. When installing the pipes, you can choose to use a wide-mouth pipe clamp or a narrow-mouth pipe clamp according to the size, structure and quantity of the pipes.
[0018] Step 3: The wide-mouth pipe clamp can be directly installed inside the expansion pipe opening with the help of locking bolts and limiting blocks. Then, the corresponding large pipeline structure is pulled into the wide-mouth pipe clamp. The bearing balls on the inside of the wide-mouth pipe clamp can assist in the stretching and movement of the pipe.
[0019] Step 4: The narrow-mouth pipe clamp is installed inside the wide-mouth pipe clamp. The narrow-mouth pipe clamp can connect to four sets of small pipeline structures at the same time. During installation, the two sets of plates are inserted from both ends of the wide-mouth pipe clamp, and then fixed by the sleeve rod and pin rod. After fixing, the narrow-mouth pipe clamp and the wide-mouth pipe clamp can be rotated.
[0020] Step 5: After completing the pipeline transfer operation, install the manhole cover on top of the manhole opening.
[0021] Compared with the prior art, the beneficial effects of the present invention are:
[0022] 1. In this invention, when installing pipes, a wide-mouth pipe clamp or a narrow-mouth pipe clamp can be selected according to the size, structure and quantity of the pipes, thereby ensuring the sealing of the pipe joint and avoiding pollution and water leakage. The wide-mouth pipe clamp can be directly installed inside the expansion pipe opening with the help of locking bolts and limiting groove blocks, and then the corresponding large pipeline structure is pulled into the wide-mouth pipe clamp. The bearing balls on the inside of the wide-mouth pipe clamp can assist the stretching and movement of the pipe and reduce the frictional resistance between the pipeline and the wide-mouth pipe clamp.
[0023] 2. In this invention, the narrow-mouth pipe clamp is installed inside the wide-mouth pipe clamp. The narrow-mouth pipe clamp adopts a split assembly structure design. Each clamp has four pipe ports on its surface, which can simultaneously connect four sets of small pipe structures. During installation, the two clamps are inserted from both ends of the wide-mouth pipe clamp. The clamps are installed and aligned using the locking groove and locking buckle on their inner sides. Then, they are fixed by the sleeve rod and pin rod. After fixing, the narrow-mouth pipe clamp and the wide-mouth pipe clamp can be rotated. By rotating, the pipe structures fixed inside can be twisted together.
[0024] 3. In this invention, a compression spring is positioned between the transfer shaft and the top mounting plate to maintain a certain distance between them. This way, if water seepage occurs inside the shaft, the accumulated water can be drained through the support groove, preventing the water level from being too high and affecting the pipeline structure inside the shaft.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0033] Please see Figure 1-2An embodiment of the present invention provides a contamination-proof composite resin manhole structure, comprising a two-section manhole body 1 and a manhole cover 2, and an elastic support 3 disposed below the two-section manhole body 1. The two-section manhole body 1 includes a through manhole 101 and a transition manhole 102. The through manhole 101 is disposed above the transition manhole 102. The transition manhole 102 is provided with expansion pipe openings 1021 around its perimeter. The interior of the expansion pipe opening 1021 is provided with a wide-mouth pipe sleeve 4, and the interior of the wide-mouth pipe sleeve 4 is provided with a narrow-mouth pipe sleeve 5. The elastic support 3 includes a bottom plate 302 and a top plate 303. The bottom plate 302 and the top plate 303 are configured as an integral structure.

[0034] The entire double-section well body 1 is supported and fixed by the elastic support 3 at the bottom. A buffer gap is designed between the double-section well body 1 and the elastic support 3. When the upper double-section well body 1 is subjected to pressure, the pressure on the double-section well body 1 can be reduced by the buffer gap. The through well 101 and the transfer well 102 that make up the double-section well body 1 can be rotated and adjusted. The through well 101 is kept at the same level as the road surface, while the lower transfer well 102 can be rotated.

The inner sleeve 1024 and the outer sleeve 1011 are rotatably connected by a bearing connecting ring 1023.
[0036] The elastic support 3 at the bottom of the shaft is placed horizontally at the bottom of the tank and fixed inside the tank using the support bolts 301 on its surface.

The sleeve 505 and the pin 506 are connected by internal threads.
[0039] When installing pipes, wide-mouth pipe clamps 4 or narrow-mouth pipe clamps 5 can be selected according to the size, structure and quantity of the pipes. Wide-mouth pipe clamps 4 can be directly installed inside the expansion port 1021 with the help of locking bolts 401 and limiting groove blocks. Then, the corresponding large pipeline structure is pulled into the wide-mouth pipe clamp 4. The bearing ball 4021 on the inside of the wide-mouth pipe clamp 4 can assist the stretching and movement of the pipe and reduce the frictional resistance between the pipeline and the wide-mouth pipe clamp 4.
[0040] The narrow-mouth pipe clamp 5 is installed inside the wide-mouth pipe clamp 4. The narrow-mouth pipe clamp 5 adopts a split assembly structure design.

[0042] Step 1: Place the elastic support 3 at the bottom of the shaft horizontally at the bottom of the tank and fix it inside the tank using the support bolts 301 on its surface. After fixing, rotate the adjusting screw sleeve 3041 above the elastic support 3 to adjust the installation distance between the elastic support 3 and the transition shaft 102.
[0043] Step 2: Adjust the spacing to make the height of the expansion port 1021 on the outside of the transfer shaft 102 consistent with the height of the pipe groove inside the tank. When installing the pipes, you can choose to use a wide-mouth pipe clamp 4 or a narrow-mouth pipe clamp 5 according to the size, structure and quantity of the pipes.
[0044] Step 3: The wide-mouth pipe clamp 4 can be directly installed inside the expansion pipe opening 1021 with the help of the locking bolt 401 and the limiting block 1022. Then, the corresponding large pipeline structure is pulled into the wide-mouth pipe clamp 4. The bearing ball 4021 on the inside of the wide-mouth pipe clamp 4 can assist the stretching and movement of the pipe.
[0045] Step 4: Narrow-mouth pipe clamp 5 is installed inside wide-mouth pipe clamp 4. Narrow-mouth pipe clamp 5 can connect to four sets of small pipeline structures at the same time. During installation, the two sets of plates are inserted from both ends of wide-mouth pipe clamp 4, and then fixed by sleeve rod 505 and pin rod 506. After fixing, narrow-mouth pipe clamp 5 and wide-mouth pipe clamp 4 can be rotated.
