Description

TECHNICAL FIELD

[0001] The utility model relates to the field of civil construction especially relates to a simple foundation pit support component. BACKGROUND

[0002] In order to prevent the foundation pit from collapsing, sliding or collapsing during construction, it is necessary to set up a foundation pit support component. The purpose of supporting the foundation pit is to ensure the stability and safety of the foundation pit. However, the existing foundation pit support device has the following problems in use:

[0003] Firstly, the structure is complex and the overall manufacturing cost is high. For example, the patent CN114319385A proposes a "protection foundation pit support device with self-rotating anti-base uplift", which connects the rotating seat and the support plate through a connecting structure. The rotating seat can extend the fixed pile inside the soil, so that the connecting rope can pull and limit the top of the support plate. At the same time, the hollow structure of the fixed pile and the rotating seat allows the filling of concrete in the hollow part inside the fixed pile and the rotating seat. The concrete flows into the soil through the through hole, thereby reinforcing the fixed structure of the fixed pile and the soil, and further strengthening the pulling structure of the top of the support plate. However, the use of this existing technology for support still requires an external power supply, which not only increases the cost, but also makes the overall operation more complex during support.

[0004] Secondly, the overall area is large and inconvenient for subsequent transportation. For example, the patent CN218713053U proposes a "foundation pit support device", which can adjust the horizontal position of the support plate through an adjusting mechanism. The foundation pit support device can adjust the position of the support plate according to the size of the foundation pit excavation, and can be applied to different sizes of foundation pit support, which is convenient to use. The support mechanism supports the support plate, the scissor mechanism makes the support plate move horizontally more stably, and the reinforcing mechanism supports and reinforces the support plate. The support plate is stably abutted on the foundation pit side wall through the support mechanism, the scissor mechanism and the reinforcing mechanism, which enhances the support effect of the device. However, after using this existing technology for support, it cannot be effectively stored, resulting in a large area occupied during subsequent transportation.
