Description

Technical Field

[0001] The utility model relates to the technical field of underground structures in construction engineering, in particular to an assembled pipeline well. Background Art

[0002] The assembled pipe well is a well structure in which various components are manufactured in advance in the factory and then transported to the construction site for rapid assembly. It is the main underground structure in the foundation of major construction projects.

[0003] A prefabricated building drainage pipe well is disclosed in Chinese patent publication number CN218970201U. The prefabricated building drainage pipe well is connected to the line through the well body structure connection ports by providing more than one well body structure connection ports on the surface of the underground structure manhole.

[0004] However, compared with the existing technologies in related fields, when constructing underground structures of construction engineering foundations, in order to facilitate the connection between the well body structural parts and the manhole of the underground structure, the diameter of the installation hole of the lower well seat is usually larger than the diameter of the well body structural parts. However, this will make it inconvenient to keep the well body structural parts in the center of the installation hole, thereby causing a difference in the thickness of the sealant between the outer wall of the well body structural parts and the inner wall of the installation hole. After long-term use, the sealant will lose its sealing effect. At the same time, well body structural parts of different diameters are used in daily use. Therefore, when the diameter or model of the well body structural parts changes, the well body structural parts are not easy to connect and install with the installation hole. Utility Model Content

[0030] As a preferred technical solution of the utility model, Figure 3 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 and Fig.10 As shown, the support block 302 is fan-shaped, a slider 3021 is fixedly provided on the side of the support block 302 away from the adjusting disk 303, a straight groove 3011 is provided at the position of the fixed shell 301 corresponding to the slider 3021, a sliding post 3022 is fixedly provided on the side of the support block 302 close to the adjusting disk 303, and an inclined groove 3031 is provided at the position of the adjusting disk 303 corresponding to the sliding post 3022.

[0031] As a preferred technical solution of the utility model, Figure 3 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 and Fig.10As shown, the adjustment component 4 includes a mounting box 401 fixedly mounted on the fixed shell 301, a rack 402 is slidably provided inside the mounting box 401, a screw 403 is rotatably provided on the mounting box 401, the rack 402 is threadedly connected with the screw 403, a movable groove is provided at a position of the fixed shell 301 corresponding to the rack 402, a plurality of meshing grooves 3032 matching with the rack 402 are provided on the outer surface of the adjustment disk 303, a rotating hole is provided at a position of the mounting box 401 corresponding to the screw 403, and the screw 403 is matched and connected with the rotating hole through a bearing, The concentric assembly 3 can be adjusted according to the required diameter of the well body structure 2.

At this time, the adjustment disk 303 can be rotated inside the fixed shell 301 by utilizing the cooperation between the rack 402 and the meshing groove 3032. When the adjustment disk 303 rotates, the cooperation between the slide column 3022 and the inclined groove 3031 and the constraint between the straight groove 3011 and the slider 3021 can make several support blocks 302 approach or move away from the center of the installation hole 101 at the same time;

[0036] S3, such as Figure 3 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 and Fig.10 As shown, when the plurality of support blocks 302 are displaced, the plurality of support blocks 302 will clamp the well structure 2.
