Description

Technical Field

[0001] This utility model relates to the field of deep foundation pit construction technology, specifically a modular inclined bracing replacement device suitable for deep foundation pit construction. Background Technology

[0002] During deep foundation pit construction, the inclined bracing structure is one of the key support systems to ensure the stability of the foundation pit. It can effectively resist the external forces such as soil pressure and water pressure on the sidewalls of the foundation pit, prevent the foundation pit from collapsing, deforming and other safety accidents, and provide a safe and reliable working environment for subsequent underground structure construction.

[0003] However, traditional deep foundation pit bracing construction methods have several problems. First, the installation and positioning of the bracing rods rely primarily on manual labor. Construction workers must transport the bracing rods to their designated positions within the foundation pit, then perform initial fixing using simple tools, followed by precise adjustments and positioning. This manual method is not only labor-intensive and inefficient, but the bracing rods are also susceptible to collisions and damage during transport and installation, affecting their structural performance. Furthermore, the limited precision of manual operation makes it difficult to ensure accurate installation of the bracing rods, resulting in poor support and failing to fully realize their intended function. Second, traditional bracing construction lacks flexibility. During deep foundation pit construction, the shape, size, and geological conditions of the pit may change, requiring timely adjustments to the bracing arrangement and parameters. However, once the traditional bracing structure is installed, it is difficult to quickly adjust or replace it. If the bracing needs to be rearranged, the existing bracing rods often need to be removed and reinstalled, which not only increases construction costs and time but may also adversely affect the stability of the foundation pit. Utility Model Content
