Description

Technical Field

[0001] The utility model belongs to the technical field of cables and relates to a high-strength prefabricated cable well structure. Background Art

[0002] A cable well is a covered, pit-like structure designed to house cable connectors and other accessories, or for cable pulling operations. Cable wells are typically prefabricated and buried directly underground during installation. However, in humid regions of southern China, both the interior and exterior of cable wells are exposed to moisture year-round, which can affect their overall strength. Therefore, to ensure sufficient strength in humid environments, it is essential to design a high-strength prefabricated cable well structure. Summary of the Invention

[0003] The purpose of the utility model is to solve the above problems in the existing technology and to propose a high-strength prefabricated cable well structure.

[0004] The purpose of the utility model can be achieved through the following technical solutions: A high-strength prefabricated cable well structure, including a prefabricated main body, characterized in that an arc-shaped reinforcement portion is provided on the entire top of the prefabricated main body, an entrance for personnel to enter is opened on the top of the prefabricated main body, openings for cables to pass through are provided on both sides of the prefabricated main body, and protruding eaves are provided on the outside of the opening. An arc-shaped protrusion 1 is provided on the top of the prefabricated main body, and two drainage grooves are provided on the bottom of the prefabricated main body. One end of the drainage groove is connected to the outside of the prefabricated main body, and the drainage groove corresponds to the position of the arc-shaped protrusion 1. An arc-shaped protrusion 2 is provided between the drainage grooves, and an arc-shaped guide portion is provided between the drainage grooves and the opening.

[0005] The working principle of the present invention is as follows: after the prefabricated main body is buried underground, personnel are allowed to enter and exit through the entrance on its top, and cables are transferred through the opening; the arc-shaped reinforcement part on the top of the prefabricated main body can effectively buffer the pressure on the top and drain the moisture on the top; the eaves outside the opening also play a role in separating and draining moisture, and the water vapor entering the interior of the prefabricated main body is guided by the internal arc-shaped protrusion 1, the arc-shaped protrusion 2 and the arc-shaped guide part, and finally enters the drainage trough for discharge, thereby avoiding moisture accumulation.

[0006] The eaves are arranged to be inclined downward.

[0007] The above structure is adopted to enhance the separation and drainage effects.

[0008] The inlet position of the prefabricated main body is offset and not located at the center.

[0009] The above structure is adopted, which is staggered with the center position of the internal cables, making it convenient for personnel to enter and operate.

[0010] The bottom of the drainage trough is arranged in an inclined manner.

[0011] The above structure is adopted to facilitate drainage.

[0012] The interior of the arc-shaped reinforcement portion is hollow.

[0013] The above structure can effectively reduce the impact of external temperature changes on the internal environment, prevent damage caused by thermal expansion and contraction, and enhance moisture-proof performance.

[0014] Compared with the existing technology, this high-strength prefabricated cable well structure has the following advantages: the utility model starts from the two aspects of drainage and waterproofing, and sets up corresponding structures. While facilitating the normal work of personnel, it can effectively adapt to humid environments, thereby ensuring the overall strength. BRIEF DESCRIPTION OF THE DRAWINGS
