Description

Technical Field

[0001] The utility model relates to the technical field of foundation pit protection, in particular to a municipal foundation pit protection device. Background Art

[0002] In municipal construction and maintenance work, it is often necessary to dig foundation pits to install or repair underground facilities. The excavation of foundation pits will expose the soil layer. If there are no proper protective measures, it may cause soil erosion, collapse or harm to the surrounding environment, especially in the rainy season or when the groundwater level is high. Therefore, taking effective foundation pit protection measures is the key to ensuring construction safety and the stability of the surrounding environment. Traditional municipal foundation pit protection methods include the use of temporary enclosures, steel sheet piles or concrete walls. Although these methods provide protection to a certain extent, they each have their own shortcomings.

[0003] First, the installation and removal process of traditional protective measures is complicated and time-consuming, which may affect the progress of projects that require rapid construction. Secondly, some protective methods such as temporary enclosures lack stability and sealing, and cannot effectively prevent soil erosion and the spread of pollutants. Although steel sheet piles and concrete walls have good stability, their installation requires professional equipment and operations, which is costly, and causes great damage to the ground, which is not conducive to environmental protection and subsequent recovery. In addition, the existing protective devices are not adjustable and flexible enough, and it is difficult to make effective adjustments according to the specific conditions of the foundation pit and construction needs. This is an obvious shortcoming under the changing conditions often faced on construction sites.

[0004] Therefore, there is a need for a new type of municipal foundation pit protection device that can be quickly installed and dismantled, can provide stable and reliable protection, and has good flexibility and adaptability to meet different construction environments and needs and solve the problems existing in the prior art. To this end, the utility model proposes a municipal foundation pit protection device to solve the above problems. Utility Model Content
