Technical Field

[0001] This utility model relates to the field of guardrails, and more particularly to guardrails for municipal roads. Background Technology

[0002] An excavation pit is a pit dug according to the foundation design location, based on the base elevation and foundation plan dimensions. Before excavation, an excavation plan should be determined based on geological and hydrological data, combined with the situation of nearby buildings, and waterproofing and drainage work should be carried out. For shallow excavations, slope protection can be used to stabilize the soil slope, and the slope should be determined according to relevant construction regulations. For deeper excavations or those near nearby buildings, excavation pit wall support methods, shotcrete wall protection methods, and even methods such as diaphragm walls and interlocking column-type bored piles can be used for large excavation pits.

[0003] Municipal road foundation pit engineering is an important part of urban infrastructure construction, mainly involving the excavation work during the laying of underground pipelines, the construction of underground passages, and the construction of public transportation facilities such as subways. When protecting the foundation pit, guardrails are needed. Existing guardrails generally consist of mounting posts at both ends and a railing in the middle.
