Description

Technical Field

[0001] This utility model relates to the field of safety protection technology for municipal road construction, specifically a temporary horizontal protection device for inspection wells. Background Technology

[0002] In urban municipal road and highway construction, manhole openings are generally protected horizontally with wooden or steel plates to prevent pedestrians and vehicles from falling into the manholes and causing potential accidents.

[0003] The following disadvantages exist when using wooden or steel plates for protective construction:

[0004] When wooden planks are used to cover the opening of inspection wells, construction vehicles can easily deform and damage the planks, creating significant safety hazards. Repairing or replacing them requires manpower and resources, reducing construction efficiency.

[0005] When steel plates are used to cover the manhole opening, the friction from vehicle tires can easily cause the plates to shift, creating gaps and posing a safety hazard. Manual restoration is required, reducing construction efficiency.

[0006] During the leveling of the roadbed and the paving of the water-stabilized layer, gaps caused by the deformation and collapse of wooden planks and the misalignment of steel plates can easily cause soil and structural layer materials to spill into the manholes, clogging the manholes and even the pipes. This requires manual cleaning of the debris in the manholes and pipes, resulting in waste of materials and labor costs, and is not conducive to the protection of the finished products. Summary of the Invention

[0007] The purpose of this invention is to solve the problems mentioned in the background art by providing a temporary horizontal protection device for inspection wells.

[0008] This utility model is achieved through the following technical solution:

[0009] A temporary horizontal protective device for inspection wells includes a center block, square casings, limiting threaded holes, supporting square steel, connecting threaded holes, limiting bolts, top springs, channel steel supports, and wire mesh. Each of the four sides of the center block is fixedly connected to a square casing. Each square casing has a limiting threaded hole. Each square casing contains a supporting square steel, which is slidably connected to the square casing. The supporting square steel has a connecting threaded hole. The limiting bolt passes through the limiting threaded hole and the connecting threaded hole and is threadedly engaged with them. Each square casing contains a top spring, one end of which is fixedly connected to the center block, and the other end of which is fixedly connected to the supporting square steel. The channel steel support is located on the well wall and fixedly connected to the well wall with bolts. The wire mesh is located on the square casing and fixedly connected to it.

[0010] Preferably, the central block is cube-shaped and the square sleeves on each side have the same length.

[0011] Preferably, the limiting threaded hole and the connecting threaded hole are the same size.

[0012] Preferably, the end of the supporting square steel is provided with a rubber plug, and the rubber plug is fixedly connected to the supporting square steel.

[0013] Preferably, there are two bolts used to connect the channel steel bracket to the well wall, and they are located at both ends of the channel steel bracket.

[0014] The present invention provides a temporary horizontal protection device for inspection wells, which has the following beneficial effects:

[0015] This device, through its structural design, allows for temporary protection of inspection wells. First, the height of the channel steel support is determined. Workers hold a center block and rotate the limiting bolt in the opposite direction, removing it from the limiting threaded hole and connecting threaded hole. At this point, the supporting square steel, under the pressure of the top spring, slides outward from the square sleeve, forming a cross shape. The cross is placed at the well opening, and plumb bobs of equal height are suspended at the four ends of the cross. Fixing points are then marked on the well wall, allowing the four channel steel supports to be fixed to the well wall. Next, workers hold the center block and align the supporting square steel with the positions of the channel steel supports. The supporting square steel, under the pressure of the top spring, slides outward from the square sleeve and rests on the channel steel support. The top spring can freely extend and retract to adjust its length according to the size of the inspection well opening. Finally, the wire mesh is fixed to the square sleeve, completing the temporary protection of the inspection well. When the construction is completed and the device is removed, simply remove the device and press the supporting square steel to align the position of the limiting threaded hole with the connecting threaded hole. Then, tighten the limiting bolt to engage the limiting bolt with the limiting threaded hole and the connecting threaded hole, and it is ready for the next use.

[0016] Compared with existing technologies, this utility model uses square steel, channel steel, and angle steel for processing, which greatly ensures the stability of the temporary horizontal protection device in the horizontal direction of the inspection well opening, eliminates the phenomenon of misalignment and deformation of the temporary protection due to external forces, prevents construction materials from falling into the inspection well, improves safety, saves a lot of manpower, reduces the waste of resources, saves materials, achieves the purpose of multiple recycling, improves the use value, and can be used multiple times after one manufacture. In practice, it reduces engineering costs, is not easily damaged, has a simple and convenient structure, saves manpower, and improves work efficiency. Attached Figure Description
