Description

Technical Field

[0001] The invention belongs to the technical field of foundation pit slope supporting equipment, and in particular relates to a foundation pit protection slope supporting device with a warning structure. Background Art

[0002] In the process of building construction, foundation pit slope protection is a very important process. The foundation pit is a soil pit excavated at the foundation design location according to the base elevation and foundation plane dimensions. After the foundation pit is excavated, the slope is prone to collapse due to the soil pressure, so it needs to be supported and sloped. The slope formed after the traditional foundation pit slope treatment is laid with waterproof film and nylon bags to prevent soil loss, and the soil is reinforced with anchor cables.

[0003] According to different standards of building design, foundation pits are divided into shallow foundation pits and deep foundation pits. Shallow foundation pits can effectively solve the problems of landslides and collapses by using slope treatment and anchor cable fixing. Due to the large depth of the foundation pit, deep foundation pits generally use support structures such as pile support, soil nail wall support, anchor support and underground continuous wall support. Although various support measures are used to prevent safety accidents from happening on the foundation pit slope according to the construction site and construction standards during construction, the soil of the foundation pit slope is disturbed, groundwater intrudes, and is affected by disaster weather and geological disasters during the construction process. Safety problems such as deformation, cracks, and soil leakage will still occur locally on the foundation pit slope, which seriously affects the normal progress of building construction. Measures need to be taken to supplement support operations on the problematic locations of the foundation pit slope.

[0004] The patent with patent announcement number CN 18531811 B discloses a slope support device for foundation pit protection with a warning structure, including a box body, a self-fixing expansion and squeezing component is connected to the box body, the left end of the self-fixing expansion and squeezing component is connected to a self-expanding pressure plate component, and the left end of the self-fixing expansion and squeezing component is connected to a warning component. When support is needed, the box body is pushed to the required position, and the self-fixing expansion and squeezing component makes the box body easy to carry. The self-fixing expansion and squeezing component is started, and the self-fixing expansion and squeezing component drives the self-expanding pressure plate component to extrude and support the slope. The self-fixing expansion and squeezing component simultaneously switches the support mode to fix and support the box body, thereby realizing convenient transportation and fixation of the box body. When the self-fixing expansion and squeezing component drives the self-expanding pressure plate component to support the slope, the self-expanding pressure plate component automatically expands, thereby realizing automatic expansion of the support area, and warning is given through the warning component when the slope collapses.

[0005] Although the above technical solution solves the technical problems of easy transportation and automatic support of foundation pit support equipment, the current support device still has the following problems: when the foundation pit is deep (more than 10 meters deep) and the location where additional support work is required is in the middle layer of the foundation pit slope, this middle layer position is far away from the construction ground and the foundation pit ground, and the existing support equipment is unable to complete the support work of the middle layer of the foundation pit slope.
