Description

Technical Field

[0001] This application relates to the field of inspection well technology, and in particular to a highly flexible prefabricated inspection well. Background Technology

[0002] Inspection wells are an important component of urban underground pipe networks. They are usually located at pipe junctions, bends, or pipe diameter changes, providing workers with access to the pipes for installation, inspection, cleaning, and maintenance. However, with the continuous development of urban construction and dynamic changes in drainage demand, drainage pipe systems may need to be expanded or modified. Existing inspection wells can only be matched with corresponding pipes. To ensure a precise match between each inspection well and pipe, more detailed planning and more on-site measurements are required, making system expansion difficult and unable to adapt to complex environmental changes. Utility Model Content

[0003] The purpose of this invention is to provide a highly flexible prefabricated inspection well to solve the above-mentioned problems.

[0004] The technical solution of this application is implemented as follows:

[0005] This application provides a highly flexible prefabricated inspection well, including a base, a well chamber on the base, a support seat on both sides of the well chamber, a connecting pipe seat connected to the side of the support seat away from the well chamber, an opening on the connecting pipe seat, and a perforation on the support seat. The opening, the perforation and the interior of the well chamber are interconnected.

[0006] A loading component is provided on the opening. The loading component includes a tube holder, which is movably disposed in the opening. The tube holder has a threaded hole extending into the opening. A screw is connected to the tube holder via a bearing. The screw is threadedly connected to the threaded hole. One end of the screw is located outside the tube holder and is equipped with a handwheel.

[0007] The loading component is provided in two sets, and the tube holder has an arc-shaped end. A receiving area for placing the tube is formed between the two sets of tube holders.

[0008] The support has a clamping component, which includes a limiting pad located inside the perforation. The support has a receiving cavity. A connecting rod is installed on the top of the limiting pad. One end of the connecting rod extends into the receiving cavity and is fitted with a pad block. An elastic element is connected to the pad block. The other end of the elastic element is connected to the end face of the receiving cavity. Through the cooperation of the elastic element, the connecting rod moves the limiting pad closer to or away from the receiving cavity.

[0009] In one embodiment, extensions are provided on both sides of the inner wall of the well chamber at positions corresponding to the perforations, and the extensions have hollowed-out portions that communicate with the perforations.

[0010] The inner ring of the hollow section has a groove, and the groove is filled with a sealing gasket;

[0011] When the pipe passes through the extension, the inner wall of the sealing gasket abuts against the outer circumference of the pipe.

[0012] In one embodiment, the pad is further provided with a support rod, which is located inside the elastic element, and the other end of the support rod extends to the outside of the bearing seat and is provided with a handle.

[0013] The handle moves the support rod, causing the elastic element to deform, which in turn causes the limiting pad to move relative to the support rod.

[0014] In one embodiment, the arc-shaped end has raised stripes, and several raised stripes are provided and spaced apart along the length direction of the tube seat. The several raised stripes form an anti-slip texture on the arc-shaped end.

[0015] In one embodiment, the support base is provided with a receiving groove, which communicates with the through hole;

[0016] When the handle moves away from the support seat and the pad moves toward the top of the receiving groove, the limiting pad gradually embeds into the receiving groove.

[0017] In one embodiment, a recess is provided at the top of the well chamber, and a well cover is movably installed on the recess. When the well cover is inserted into the recess, the well cover covers the interior of the well chamber.

[0018] In one embodiment, the bottom of the limiting pad is provided with an arc-shaped groove, and when the limiting pad abuts against the tube body, the arc-shaped groove fits against the outer periphery of the tube body.

[0019] In one embodiment, a number of mounting holes are provided on the recess and are spaced apart along the circumferential direction of the recess.

[0020] The manhole cover has a raised part at the position corresponding to the mounting hole. When the manhole cover is installed in the recessed part, the raised part is embedded in the mounting hole.

[0021] In one embodiment, the base is provided with countersunk holes, and the countersunk holes are provided in a plurality of them and are spaced apart along the circumference of the base.

[0022] The advantages or beneficial effects of the above technical solutions include at least the following:

[0023] This application discloses a highly flexible prefabricated inspection well. Based on the size of the pipe to be installed, the screw rod is moved by rotating a handwheel on the loading component, causing the pipe-inserting seat to move in the direction of rotation of the screw rod. Since the loading component has two sets, the spacing between the two sets of pipe-inserting seats can be adjusted by moving them closer or further apart, facilitating the installation of pipes of different sizes on the pipe-inserting seats. Furthermore, the bearing seat is equipped with a limiting pad connected to a connecting rod, and one end of the connecting rod is equipped with a pad block connected to an elastic element. Therefore, when part of the pipe passes through the perforation provided in the bearing seat, the elastic element can move the pad block, causing the connecting rod to clamp the limiting pad from above the pipe, thereby further improving the stability of the pipe installation. Through the cooperation of the loading component and the clamping component, the sides and top of the pipe can be supported and limited, enabling the installation of pipes of different sizes in the inspection well. This solves the problem that traditional inspection wells can only install pipes of the same size, resulting in low installation flexibility and limitations. Attached Figure Description

[0042] The names of the messages or information exchanged between multiple devices in the embodiments of this application are for illustrative purposes only and are not intended to limit the scope of these messages or information.

[0043] Reference Figures 1-4 A highly flexible prefabricated inspection well includes a base 1, a well chamber 2 on the base 1, support seats 3 on both sides of the well chamber 2, and a connecting pipe seat 4 connected to the side of the support seat 3 away from the well chamber 2. The base 1, well chamber 2, support seats 3 and connecting pipe seat 4 are all made of concrete by casting with molds. The connecting pipe seat 4 has an opening 41, and the support seat 3 has a perforation 31. The opening 41, the perforation 31 and the interior of the well chamber 2 are interconnected.

[0044] A loading component 5 is provided on the opening 41. The loading component 5 is used to load and support the pipeline. The loading component 5 includes a pipe seat 51, which is made of rubber. The pipe seat 51 is movably disposed in the opening 41. The pipe seat 4 has a threaded hole extending into the opening 41. A screw component 52 is connected to the pipe seat 51 through a bearing component. The bearing component ensures that the pipe seat 51 will not rotate synchronously when the screw component 52 rotates. The screw component 52 is threadedly connected to the threaded hole. One end of the screw component 52 is located outside the pipe seat 51 and is equipped with a handwheel 521. The handwheel 521 allows the operator to easily rotate the screw component 52, thereby driving the pipe seat 51 to move relative to it.

[0045] The loading component 5 is provided with two sets, and the tube holder 51 has an arc-shaped end 511. A receiving area for placing the tube is formed between the two sets of tube holders 51. The arc-shaped end 511 facilitates the placement of the annular tube.

[0046] The support base 3 has a clamping component 6 for clamping the pipe. The clamping component 6 includes a limiting pad 61, which is made of rubber and has a certain degree of extensibility. The limiting pad 61 is located inside the perforation 31. The support base 3 has a receiving cavity 32. A connecting rod 62 is installed on the top of the limiting pad 61. One end of the connecting rod 62 extends into the receiving cavity 32 and is fitted with a pad block 621. An elastic element 63 is connected to the pad block 621. The elastic element 63 is a pressure spring or a telescopic spring in the prior art. The other end of the elastic element 63 is connected to the end face of the receiving cavity 32. Through the cooperation of the elastic element 63, the connecting rod 62 moves the limiting pad 61 closer to or away from the receiving cavity 32.

[0047] Based on the above structure, by installing two sets of pipes onto the opening 41 of the connector 4, the two sets of pipes converge within the well chamber 2 via a connecting pipe, thus completing the pipe installation. When the pipe is located on the opening 41, depending on the pipe size, the operator rotates the handwheel 521 to drive the screw 52 to rotate, causing the pipe-inserting seat 51 to move in the direction of rotation of the screw 52, ​​thereby adjusting the distance between the two sets of pipe-inserting seats 51, making them closer or farther apart, so that the outer circumference of the pipe abuts against the arc-shaped ends 511 of the two sets of pipe-inserting seats 51 respectively. And when the pipe passes through the through hole 31 provided in the bearing seat 3, the clamping component 6... The limiting pad 61, in cooperation with the pad block 621 and the elastic element 63, can drive the support rod 64 to move, thereby clamping the limiting pad 61 from above the pipe. The screw element 52 drives the pipe placement seat 51 to move, which can complete the placement operation of pipes of different sizes. In addition, with the cooperation of the clamping component 6, pipes of different sizes can be clamped, avoiding the impact of internal liquid flow or shaking caused by external collision. This allows the inspection well to install pipes of different sizes, improves the installation flexibility, and solves the problem that existing inspection wells can only be matched with the same type of pipe, resulting in limitations.

[0048] In one embodiment, reference is made to Figures 1-3 An extension 21 is provided on both sides of the inner wall of the well chamber 2, corresponding to the position of the perforation 31. The extension 21 has a hollow part and communicates with the perforation 31. The extension 21 further supports the pipeline. The hollow part has a groove 211 in the inner ring. The groove 211 is filled with a sealing gasket 212. The sealing gasket 212 is formed by a water-stop strip made of polymer inorganic water-absorbing and expanding material and rubber. When the pipeline passes through the extension 21, the inner wall of the sealing gasket 212 abuts against the outer circumference of the pipeline. Through the abutment between the sealing gasket 212 and the pipeline, the sealing performance of the pipeline in the well chamber 2 can be further improved.

[0049] In one embodiment, reference is made to Figure 1 , Figure 3 and Figure 6 The pad 621 is also provided with a support rod 64, which is located inside the elastic element 63. The other end of the support rod 64 extends to the outside of the bearing seat 3 and is provided with a handle 641. The support rod 64 is moved by the handle 641, which causes the elastic element 63 to deform, thereby causing the limiting pad 61 to move relative to it. Through the cooperation of the support rod 64 and the handle 641, the user can easily adjust the position of the limiting pad 61, thereby accurately controlling the position of the limiting pad 61 and facilitating the installation of pipes of different sizes.

[0050] In one embodiment, reference is made to Figure 1 and Figure 4The arc-shaped end 511 has raised stripes 5111, which are made of rubber. Several raised stripes 5111 are provided and distributed at intervals along the length of the pipe seat 51. Several raised stripes 5111 form anti-slip texture on the arc-shaped end 511. When the pipe is located on the arc-shaped end 511, the outer circumference of the pipe abuts against the raised stripes 5111. By making the outer circumference of the pipe abut against the raised stripes 5111, the position of the pipe can be fixed more accurately, ensuring that the pipe remains in the correct position after installation and maintenance. In addition, the raised stripes 5111 can increase the friction between the pipe and the arc-shaped end 511, preventing the pipe from sliding in the inspection well due to water flow impact, soil movement or other external forces.

[0051] In one embodiment, reference is made to Figure 1 , Figure 3 and Figure 6 The support seat 3 is provided with a receiving groove 33, which is connected to the through hole 31. When the handle 641 moves away from the support seat 3 and the pad 621 moves toward the top of the receiving groove 33, the limiting pad 61 gradually embeds into the receiving groove 33. When the limiting pad 61 is located in the receiving groove 33, the pipe can pass through the maximum inner diameter of the through hole 31, thereby avoiding the limiting pad 61 from blocking the installation of larger pipes.

[0052] In one embodiment, reference is made to Figure 1 , Figure 2 and Figure 5 The top of the well chamber 2 is provided with a recess 22, and a well cover 7 is movably installed on the recess 22. When the well cover 7 is inserted into the recess 22, the well cover 7 covers the interior of the well chamber 2. Since the well chamber 2 is a hollow structure, in order to avoid accidents, the well cover 7 is installed on the well chamber 2 to cover the hollow part. The well cover 7 installed on the recess 22 can limit the position of the well cover 7.

[0053] The recessed portion 22 is provided with mounting holes 221. Several mounting holes 221 are provided and are distributed at intervals along the circumference of the recessed portion 22. The manhole cover 7 is provided with a protrusion 71 corresponding to the position of the mounting hole 221. When the manhole cover 7 is installed in the recessed portion 22, the protrusion 71 is embedded in the mounting hole 221. Through the cooperation of the mounting hole 221 and the protrusion 71, the manhole cover 7 can be further limited when it is installed on the top of the manhole chamber 2, thereby preventing the manhole cover 7 from detaching from the position of the manhole chamber 2 when it is subjected to external impact.

[0054] In one embodiment, reference is made to Figure 1 , Figure 3 and Figure 6The bottom of the limiting pad 61 is provided with an arc-shaped groove 611. When the limiting pad 61 abuts against the tube body, the arc-shaped groove 611 fits against the outer periphery of the tube body. The setting of the arc-shaped groove 611 enables the limiting pad 61 to better abut against the tube body, thereby supporting and fixing it from above the tube body.

[0055] In one embodiment, reference is made to Figures 1-3 The base 1 is provided with countersunk holes 11. Several countersunk holes 11 are provided and distributed at intervals along the circumference of the base 1. The countersunk holes 11 are provided so that when the base 1 is installed on the ground, bolts can be placed and the bolts can pass through the countersunk holes 11 to connect with the ground, thereby further improving the stability of the manhole installation.

[0056] In one embodiment, reference is made to Figure 1 and Figure 2 Several handrails 23 are provided in the well chamber 2 at intervals. The handrails 23 allow the operator to move to the inside of the well chamber 2 by going up the top of the well chamber 2 along the handrails 23.

[0057] In the description of this application, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.
