Description

Technical Field

[0001] This utility model belongs to the field of inspection well technology, specifically, it relates to a large-diameter composite inspection well. Background Technology

[0002] Inspection wells are installed to facilitate the maintenance and installation of underground infrastructure such as power supply, water supply, drainage, sewage, communications, cable TV, gas pipes, and street light lines in cities. They are generally installed at pipe junctions, bends, changes in pipe diameter or slope, and at regular intervals on straight pipe sections to facilitate periodic inspections of ancillary structures. Existing inspection wells are mainly made of cement or plastic. Cement inspection wells are bulky and heavy, inconvenient to transport and hoist, and have poor sealing. Plastic inspection wells often use prefabricated well casings connected to the pipes by heat fusion or rubber ring sockets, which can easily lead to leakage at the joints due to settlement or temperature stress. Prefabricated well casings have limited ring stiffness and are prone to deformation and damage when buried at a depth of more than 5 meters. They also require excavation and replacement of the entire pipe section, resulting in long construction cycles and low efficiency.

[0003] Therefore, existing technologies need further improvement and enhancement. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a large-diameter composite inspection well.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: A large-diameter composite inspection well includes a well chamber, a well shaft, and transition sections disposed on both sides of the well shaft. A cut is made on the surface of the well chamber. The diameter of the well shaft is adapted to the cut and is perpendicular to the well chamber and located in the middle. An auxiliary net is disposed on the surface of the transition section. A support frame can be detachably installed on the surface of the well chamber.

[0006] In a preferred embodiment of this application, the support frame includes a first adjustment frame and a second adjustment frame, which have the same structure and are fastened together to complete the enclosure of the well chamber.

[0007] In a preferred embodiment of this application, the first adjustment frame includes a horizontal connecting frame and a vertical connecting frame, with the horizontal connecting frames provided at the upper and lower ends of the vertical connecting frame, and the horizontal connecting frames of the first adjustment frame and the second adjustment frame cooperating with each other.

[0008] In a preferred embodiment of this application, the first adjustment frame and the second adjustment frame have a butt joint in the transverse connecting frame of one of them, and a butt joint in the other.

[0009] In a preferred embodiment of this application, the horizontal connecting frame is provided with multiple detachable connecting rods, and the two ends of the vertical connecting frame are provided with multiple plug-in interfaces that are adapted to the detachable connecting rods.

[0010] In a preferred embodiment of this application, one end of the transition section is connected to the well chamber, and the other end is connected to an external connecting pipe. The diameter of the external connecting pipe is smaller than the diameter of the well chamber, and the diameter of the transition section decreases accordingly.

[0011] In a preferred embodiment of this application, the auxiliary mesh is a steel wire mesh, and the auxiliary mesh is adapted to the shape of the transition section.

[0012] In a preferred embodiment of this application, a connecting ring is provided with an upward protrusion at the top of the cut, the well shaft is adapted to the connecting ring, and a sealing ring is built into the inner wall of the connecting ring.

[0013] In a preferred embodiment of this application, the inspection well also includes a lifting ring, which is placed on a support frame.

[0014] After adopting the above technical solution, the large-diameter composite inspection well provided by this utility model has the following beneficial effects compared with the prior art.

[0015] 1. This application provides a large-diameter composite inspection well. By setting a notch on the surface of the well chamber and connecting the well chamber to the well shaft through the notch, it is easier to assemble and disassemble and has higher strength compared to a one-piece molded inspection well structure. Furthermore, the structure of the support frame and auxiliary net not only facilitates the connection between the support frame, well shaft, and well chamber, improving their fixing strength, but also allows for better cement compatibility in the transition area where the diameter changes, assisting the cement in forming a reinforced area and improving the overall strength.

[0016] 2. As a preferred embodiment of this application, this application sets the support frame to be an adjustable structure, which can adapt to the large-diameter structure to which this application is adapted. At the same time, it can also further adapt to well chamber structures with different diameters according to the adjustable first and second adjustment frames, which has higher adaptability. Moreover, the left and right symmetrical splicing method makes it easier to install the structure and makes the processing more convenient. Attached Figure Description

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0021] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", and "outer" 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 utility model 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. Therefore, they should not be construed as limitations on this utility model.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0024] like Figures 1 to 5 As shown, this utility model provides a technical solution: a large-diameter composite inspection well, including a well chamber 1, a well shaft 2 and transition portions 12 disposed on both sides of the well shaft 2. A cutout 3 is opened on the surface of the well chamber 1. The diameter of the well shaft 2 is adapted to the cutout 3, perpendicular to the well chamber 1, and located in the middle. An auxiliary net 4 is disposed on the surface of the transition portion 12. A support frame 5 is detachably installed on the surface of the well chamber 1.

[0025] Among them, such as Figure 1 and Figure 2 As shown, the well chamber 1 is a cylindrical structure, and the cut 3 is an annular cut 3, which is used to connect with the cylindrical well tube 2 structure. In order to reduce costs, the well chamber 1 structure of this application is made of plastic pipe material, so the processing is simple and the cost is low. In order to improve its strength, an auxiliary net 4 and a support frame 5 structure are set.

[0026] For well chamber 1, for ease of installation, such as Figure 2 As shown, a connecting ring 6 is provided with an upward protrusion at the top of the cut 3. The well shaft 2 is adapted to the connecting ring 6, and a sealing ring 62 is built into the inner wall of the connecting ring 6.

[0027] Optionally, a threaded ring 61 can be provided at the connecting end of the well shaft 2, and a threaded structure can be provided on the inner wall of the connecting ring 6 to facilitate the assembly of the two. In addition, at least one groove 63 structure is provided on the inner side wall of the connecting ring 6, and a sealing ring 62 is placed in the groove 63 structure to improve the sealing effect through the threaded fittings and the sealing ring 62.

[0028] Understandably, in order to further improve the sealing effect, after the well shaft 2 and well chamber 1 are assembled and connected, the pipes can be welded together by high-strength, high-density welding.

[0029] As a preferred embodiment of this application, such as Figure 4 As shown, the support frame 5 includes a first adjustment frame 51 and a second adjustment frame 52, which have the same structure and are fastened together to complete the enclosure of the well chamber 1.

[0030] For ease of description, this application takes the first adjusting frame 51 as an example. The first adjusting frame 51 includes a horizontal connecting frame 7 and a vertical connecting frame 8. The horizontal connecting frames 7 are provided at the upper and lower ends of the vertical connecting frame 8. The horizontal connecting frames 7 of the first adjusting frame 51 and the second adjusting frame 52 cooperate with each other. As can be seen from the figure, the structure of a single first adjusting frame 51 is C-shaped when viewed from the side. By docking and assembling with the second adjusting frame 52, it completes the enclosure and protection of the well chamber 1. In order to facilitate the docking of the two, one of the horizontal connecting frames 7 of the first adjusting frame 51 and the second adjusting frame 52 has a butt joint, and the other has a butt joint, so that the first adjusting frame 51 and the second adjusting frame 52 are installed by plugging in, which improves the convenience of their assembly and disassembly.

[0031] Furthermore, to accommodate well chamber 1 structures of different diameters, taking the first adjusting frame 51 as an example, the horizontal connecting frame 7 can be made of multiple telescopic rods 9. The telescopic rods 9 adopt a structure with multiple extension stops to match the second adjusting frame 52 to adapt to different horizontal dimensions of the well chamber 1. For vertical dimensions, the vertical connecting frame 8 can be set with a structure similar to the horizontal connecting frame 7, also using multiple telescopic rods 9 to adapt to well chamber 1 structures of different sizes. Of course, to ensure strength, multiple horizontal telescopic rods 9 are set on the surface of the first vertical connecting frame 8 along the vertical direction, so that the entire support frame 5 forms a structure similar to a square frame.

[0032] The size of the opening 3 of the well chamber 1 will inevitably change for different sizes of well chamber 2. Therefore, the connecting part of the horizontal connecting frame 7 should not block the opening 3. To address this, this application can provide multiple detachable connecting rods horizontally and multiple plug-in interfaces that are compatible with the detachable connecting rods at both ends of the vertical connecting frame 8. This can accommodate different sizes of openings 3, increase or decrease the number of detachable connecting rods, or adjust the position of the detachable connecting rods to avoid affecting the normal installation of the opening 3 and the well chamber 2.

[0033] As a preferred embodiment of this application, such as Figure 1 As shown, one end of the transition section 12 is connected to the well chamber 1, and the other end is connected to the external connecting pipe 13. The diameter of the external connecting pipe 13 is smaller than the diameter of the well chamber 1, and the diameter of the transition section 12 decreases.

[0034] Regarding the structure of the transition section 12, in one optional embodiment, a funnel-shaped channel pipe can be welded to create the transition structure, facilitating the assembly of the subsequent connecting pipe 13. In another embodiment, since the well chamber 1 itself uses a plastic pipe structure, assembly openings 10 can be pre-cut at both ends of the well chamber 1 before use. The assembly openings 10 are triangular in structure, and the reserved portion is also triangular. During use, the triangular structures can be brought together inward. During the process of bringing together, the assembly openings 10 gradually disappear and become small gaps. These gaps are glued using a glue gun, so that the diameter of the part where the assembly openings 10 were cut can gradually decrease, forming the transition section 12. The welding material used by the glue gun is composed of self-formulated high-density polyethylene material, etc. Its greatest characteristics are strong sealing ability, high strength, and strong adhesion.

[0035] Furthermore, the auxiliary mesh 4 is a steel wire mesh, adapted to the shape of the transition section 12, and wrapped around or fitted onto the surface of the transition section 12. This facilitates subsequent cement pouring, allowing the cement to be attached using the auxiliary mesh 4 and the support frame 5, thereby improving the overall strength of the inspection well. Of course, to accommodate inspection wells of different sizes, multiple single-piece auxiliary mesh 4 structures can also be used, adhered and spliced ​​onto the surface of the transition section 12.

[0036] The inspection well also includes a lifting ring 11, which is placed on the support frame 5. Under normal conditions, the lifting ring 11 is suspended inside the support frame 5 and is in a movable state. When pouring cement, the lifting ring 11 can be placed in the upper position, and the lower half of the lifting ring 11 can be fixed by cement, so that the lifting ring 11 is exposed outside the cement, making it convenient for the user to pull the entire inspection well by lifting the lifting ring 11.
