Description

Technical Field

[0001] This utility model relates to the field of prefabricated culvert technology, and in particular to a prefabricated anti-settlement and waterproof cable culvert. Background Technology

[0002] The laying of underground pipelines in urban planning is a major challenge. After the development of related technologies, from direct burial of pipelines to on-site casting of culverts, the technology of assembling and laying precast concrete culverts has begun to be popularized. The design and manufacturing level and construction and installation process of precast concrete culverts are the key to the quality of underground culvert laying. Precast square culverts are a type of box-shaped culvert made of high-strength reinforced concrete in a factory and then hoisted and connected on the construction site.

[0003] Chinese Patent Publication No. CN206457846U discloses a high-efficiency precast concrete culvert that can be assembled vertically. The culvert includes an upper culvert and a lower culvert. The upper culvert has an arched top, and the lower culvert is a square trough. Stepped fitting structures are provided below the upper culvert and above the lower culvert, allowing the two culverts to be assembled as a single unit. Several sealing elements are installed within the fitting structures. Vertical steel strand tensioning holes are correspondingly located on both sides of the upper and lower culverts. Several cable supports are fixed to the inner wall of the upper culvert, and water pipe supports are fixed to the inner wall of the lower culvert. This precast concrete culvert not only features lightweight components, offering convenience in transportation, production, and installation, but also improves the construction efficiency of urban underground utility tunnels and saves construction costs.

[0004] Traditional cable culverts lack effective anti-settlement structures on their outer sides. Under long-term stress, they are prone to settlement, which not only undermines the structural stability of the culvert itself but also causes significant impact on its connection points. The lack of necessary support structures at the joints makes them susceptible to deformation under the influence of external environmental factors. If the deformation exceeds a certain range, it can lead to serious problems such as detachment or misalignment of the spliced ​​cable culverts, posing significant safety hazards to the laying, operation, and maintenance of cables. Utility Model Content

[0005] The main purpose of this utility model is to provide a prefabricated anti-settlement and waterproof cable culvert, which can effectively solve the problem mentioned in the background art that traditional cable culverts are not equipped with effective anti-settlement structures on the outside. Under long-term load-bearing, they are prone to settlement, which not only damages the structural stability of the cable culvert itself, but also causes great impact on its connection parts. The connection of the cable culvert lacks the necessary support structure, and is prone to deformation under the influence of external environmental factors. Once the deformation exceeds a certain range, it may cause serious problems such as detachment and misalignment of the spliced ​​cable culvert, which brings great safety hazards to the laying, operation and maintenance of cables.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A prefabricated anti-settlement and waterproof cable culvert includes a culvert body and a mounting base plate. The mounting base plate is supported on the bottom of the culvert body. A connecting bearing is fixedly connected to one end of the culvert body, and a connecting plug is fixedly connected to the other end of the culvert body. A sealing ring is bonded to the inner side of the connecting bearing. Reinforcing corners are fixedly connected to the interior of the culvert body near the four corners. Rope-passing holes are opened inside the reinforcing corners. Multiple cable placement racks are fixedly installed on the inner surface of the culvert body. An anti-settlement structure is connected to the outer side of the mounting base plate.

[0008] As a further embodiment of this utility model, the anti-settlement structure includes a mounting frame, a limiting rod, and a guide seat. The mounting frame is fixedly installed on the outside of the mounting base plate, and the top of the mounting frame abuts against the outer surface of the culvert body. The limiting rod passes through one side of the mounting frame, and the guide seat is fixed to the bottom of the mounting frame.

[0009] As a further embodiment of this utility model, an anti-detachment connector is fixedly connected to the end of the limiting rod, a guide roller is rotatably connected to the inner side of the mounting bracket, and a rotating part is connected between the guide roller and the guide seat.

[0010] As a further embodiment of this utility model, the outer surface of the guide roller is provided with a groove that matches the limiting rod, and the limiting rod moves outward to insert into the embedded layer.

[0011] As a further embodiment of this utility model, a fixing frame is provided on the inner side of the connecting bearing, the fixing frame is adapted to the outer contour of the connecting plug, a locking pin is screwed into the top of the connecting bearing, and a locking groove adapted to the locking pin is opened on the top of the connecting bearing.

[0012] As a further embodiment of this utility model, the fixing frame is fixedly connected to the connecting bearing by a locking pin and a locking groove, and the fixing frame is located at the connection center of the connecting bearing and the connecting plug.

[0013] The beneficial effects of this utility model are as follows:

[0014] By setting up an anti-settlement structure, it is possible to insert it outwards during the laying and installation of the cable culvert, which can limit the vertical position of the cable culvert and effectively prevent the cable culvert from settling.

[0015] By setting a fixed frame and locking pins, the connection of the cable culvert can be fixed and supported, which can improve the connection stability of the cable culvert and prevent deformation at the connection. Attached Figure Description
