[0002] At present, with the development of municipal construction technology, construction equipment and urban construction needs, municipal pipeline construction is more common than before. For example, for comprehensive pipe trenches that are buried deeper but do not meet the standards of deep foundation pits, there are more requirements for the excavation method during the pipeline installation and laying process, as well as newer requirements for the rational use of spaces such as cities, farmlands, and hills, as well as more requirements for innovation in construction technology.

[0003] The excavation of trench construction increases with the increase of pipe diameter and depth, and the slope ratio increases accordingly. The excavation area is also constantly expanding. Due to the limited buildings, crops, and relocation sites, as well as the complex and diverse municipal road facilities, the width of the trench excavation is inevitably insufficient. Once encountering unstable soils such as quicksand, paddy field silt, backfill soil, and weathered rock, landslides often occur during excavation, which not only causes over-excavation and over-excavation of the trench earthwork, but also destroys the overall stability of the installed pipe sockets and fittings, affects the control elevation of pipeline laying, and damages a series of quality problems such as finished product damage, causing rework, etc., and even directly endangers the safety of facilities such as buildings, high-voltage cables, natural gas pipelines, low-voltage cables, and municipal sewage pipelines in the construction area, as well as the safety of life and property of installers. Therefore, we propose a pipeline installation protection device. Summary of the invention
