Description

Technical Field

[0002] High-pressure jet grouting piles are an engineering technology used for foundation treatment and foundation pit reinforcement. In construction projects, when it is necessary to dig a foundation pit in a soft soil foundation or a deep foundation, foundation reinforcement is usually required to ensure the stability of the soil around the foundation pit and prevent foundation settlement. High-pressure jet grouting piles are a commonly used foundation reinforcement technology, which can effectively improve the bearing capacity and compressive strength of the soil.

[0003] After searching, the applicant found that a Chinese patent disclosed "a foundation pit reinforcement based on high-pressure rotary jet grouting piles", and its publication (announcement) number is "CN214328848U". This patent mainly provides a plurality of inclined beams on the soil nail wall for reinforcing the soil nail wall. The inclined beams are formed by a plurality of inclined beam sections connected to each other, and two adjacent inclined beam sections are detachably connected by a connecting mechanism. The inclined beams are fixedly connected to the soil nail wall and the foundation pit body through a plurality of first anchor rods. This application has the function of enhancing the reinforcement strength of the foundation pit reinforcement structure, but it is difficult to adjust the height of the inclined beam according to the height of the foundation pit while the device supports the foundation pit, resulting in the need to reassemble when facing foundation pits of different heights, wasting a lot of time and energy of the staff.
