Description

Technical Field

[0001] The utility model relates to the technical field of underground pipeline laying, in particular to protective equipment for rapid laying of underground pipelines. Background Art

[0002] A pipeline foundation pit refers to an earthwork project that excavates a certain depth and area below the ground, primarily used for foundation work for laying pipelines and equipment. During the construction of a pipeline foundation pit, attention must be paid to safety issues to ensure the safe progress of the construction process. The purpose of excavating a pipeline foundation pit is to create a certain space underground for the installation of pipelines or equipment. The excavation and support of this foundation pit are crucial to ensuring safety and stability during construction, and involve the comprehensive application of geological engineering, geotechnical engineering, structural engineering, and geotechnical testing technology. Traditional pipeline foundation pits generally use steel sheet pile support, which requires a large amount of material, a large working surface, and a large disturbance to the surrounding area. Alternatively, they use slope excavation, where the slope ratio must meet regulatory requirements and the excavation volume is large. This poses a significant threat to the lives of construction workers in the event of a construction accident, so protective equipment that can effectively ensure the safety of construction workers is needed.
