Description

TECHNICAL FIELD

[0002] In recent years, with the large rise of high-rise buildings and the development and utilization of urban underground space, the depth of foundation pits is getting deeper and deeper, especially a large number of foundation pits are excavated in densely built-up areas, which makes the support technology of foundation pits more important. Foundation pit support refers to a series of measures taken in earthwork engineering to ensure the stability and safety of foundation pit construction, which not only ensures the safety of the entire support structure during construction, but also controls the deformation of the support structure and the surrounding soil to ensure the safety of the surrounding environment. For deep and large foundation pits and foundation pits with high safety requirements, an internal support support structure is often used.

[0003] The conventional method of the existing foundation pit support structure is pile foundation support. First, a pile foundation drilling operation is performed using a drilling machine. After drilling is completed, pile foundation grouting is performed. Then, reinforced concrete grouting material is injected into the drill hole to fill the pores and form a pile foundation support structure. Before the grouting material solidifies, a pre-embedded steel bar or steel cage is installed. After the grouting material is fully solidified, the pile foundation is solidified to form a retaining pile. A plurality of retaining piles arranged side by side are used as the support structure of the foundation pit and are fixed in the surrounding soil of the foundation pit to enhance the stability of the soil. For the above foundation pit support measures, when facing deep and large foundation pits, only the retaining piles are used as the support structure of the foundation pit, and there is a lack of support structure to support the retaining piles. There is still a defect of insufficient stability of the foundation pit. In addition, for foundation pits of different shapes, it is necessary to set up a peripheral support structure, especially for the corners of the foundation pit, which is more unstable. For foundation pits of different specifications, there is a lack of support components that can adapt to different specifications and increase protection, which greatly affects the construction progress and cannot meet the use requirements.
