Description

Technical Field

[0001] This utility model relates to the field of square wells, and in particular to a prefabricated square well that is easy to position and install. Background Technology

[0002] The construction of square wells typically involves multiple processes on-site, such as earthwork excavation, formwork erection, rebar tying, and concrete pouring. Each process requires a certain amount of time to complete, and there is a sequence and mutual constraints between the processes, resulting in a long overall construction cycle. With the development of industrialized construction, prefabricated assembly technology is being used more and more widely in municipal engineering. Prefabricated square wells involve prefabricating the various components of the square well in a factory and then transporting them to the construction site for assembly. This method can greatly improve construction efficiency and reduce the workload and environmental impact of on-site construction.

[0003] However, existing prefabricated square manholes are difficult to quickly position and connect with each other during installation. When installing and fitting the manhole panels together, mortar needs to be applied and then the two manhole panels are joined together. This connection and installation method is relatively troublesome and reduces the installation speed of the square manhole. Therefore, we propose a prefabricated square manhole that is easy to position and install to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a prefabricated square well that is easy to position and install, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A prefabricated square well for easy positioning and installation includes a lower well wall panel, an upper well wall panel above the lower well wall panel, and a well cover assembly above the upper well wall panel. Two reinforcing steel plates are fixedly embedded inside both the upper and lower well wall panels. A connecting seat is fixedly connected to one side of each of the two reinforcing steel plates. Two connecting pieces are fixedly connected to the bottom surface of the upper well wall panel, with the bottom ends of both connecting pieces extending into the interior of the connecting seats. Threaded connecting holes are opened on the opposite sides of the two connecting seats, and fixing bolts are threaded into the inner walls of both threaded connecting holes.

[0007] In a further embodiment, the manhole cover assembly includes a manhole cover plate, the outer surface of which has two grooves, the bottom end of which has a positioning protrusion, and the inner ring of the upper manhole wall plate is fixedly connected to a rectangular positioning ring, the outer surface of which contacts the inner wall of the rectangular positioning ring.

[0008] In a further embodiment, a fixing groove is provided on one side of each of the two connectors that are close to each other, and the outer surfaces of the two fixing bolts are threadedly connected to the inner walls of the two fixing grooves respectively.

[0009] In a further embodiment, two lifting components are fixedly connected to the outer surfaces of both the upper and lower well walls. Through holes are provided on the bottom surfaces of both the upper and lower well walls. Multiple reinforcing bars are fixedly embedded inside the lower well wall, and each reinforcing bar is circular in shape.

[0010] In a further embodiment, the upper surface of the lower well wall plate is provided with a first rectangular groove, and the upper surface of the upper well wall plate is provided with a second rectangular groove.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention enables rapid positioning between the upper and lower well wall panels through the cooperation of the connector and the connecting seat. It allows the upper well wall panel to be quickly positioned and installed above the lower well wall panel. Furthermore, the tightening of the fixing bolts, threaded connecting holes, and fixing grooves ensures precise determination of the relative positions of the upper and lower well wall panels, avoiding positional deviations during installation. Compared to traditional mortar-applied joints, the use of fixing bolts eliminates the need to wait for the mortar to harden, allowing for rapid connection and increasing the installation speed of the manhole. The cooperation between the positioning protrusion and the rectangular positioning ring accurately and quickly positions the manhole cover above the upper well wall panel, further accelerating the positioning and installation of the manhole cover.

[0023] The working principle of this utility model is as follows: During installation, the lifting parts 11 on the outer surfaces of the upper well wall plate 2 and the lower well wall plate 1 can be used to easily lift each component to the installation position. Then, the connecting part 6 on the bottom surface of the upper well wall plate 2 is inserted into the interior of the upper connecting seat 7, which can position the relative positions of the upper well wall plate 2 and the lower well wall plate 1. After the connecting part 6 is inserted into the interior of the connecting seat 7, the fixing bolt 10 is screwed into the fixing groove 8 through the threaded connecting hole 9, which can tightly connect the upper well wall plate 2 and the lower well wall plate 1 together. When installing the well cover assembly 3, the positioning protrusion 302 is aligned with the rectangular positioning ring 5, so that the outer surface of the positioning protrusion 302 contacts the inner wall of the rectangular positioning ring 5, which can determine the position of the well cover plate 301 on the upper well wall plate 2, and realize the rapid positioning and installation of the well cover assembly 3.
