Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of municipal engineering, more particularly, it relates to a stable anti-settling well body for municipal engineering. BACKGROUND

[0002] The well body is usually used to connect the ground and the underground structure to form a passage for people or objects to enter the underground structure from the ground.

[0003] In order to adapt to different use requirements in municipal engineering, the types and functions of well bodies are usually various, and common ones are various types of reserved wells, inspection wells and shafts, etc. Municipal well bodies are very common in daily life. With the passage of time, the planning of the city is gradually changing. Some well bodies that were once on both sides of the road will be offset to the road surface area as the road position changes. At the same time, some well bodies will be in the road surface area in order to meet the needs of the corresponding planning. The road surface is usually used to meet the needs of pedestrians and vehicles, so the structural design of the road surface usually meets the corresponding use requirements. However, the bottom end of some well bodies is usually lower than the roadbed, so the structural strength of the structure supporting the bottom end of the well body is less than the roadbed strength of the surrounding road surface. With the passage of time, under the pressure of pedestrians and vehicles, the well body will sink, causing the top surface of the well body to be lower than the surrounding road surface. When a vehicle passes through this place, it will appear bumpy. The occurrence of this situation will make the road surface around the well body more prone to damage, and at the same time, it will make the well body more prone to sinking. Therefore, a structure is needed to solve the problem that some existing well bodies for municipal engineering placed in the road surface are prone to subsidence, which in turn causes the road surface around the well body to be prone to damage.

[0004] Therefore, a new scheme needs to be proposed to solve this problem. SUMMARY
