Abstract
Description
Technical Field

[0002] In municipal engineering and construction, the stability and seepage prevention performance of the soil between foundation pit piles are crucial. Due to geological conditions, construction errors, or design flaws, gaps often exist between piles. If these gaps are not properly addressed, they can easily lead to the leakage of water, soil, and other substances, thus affecting the stability and safety of the entire structure. To solve this problem, shotcrete reinforcement devices have emerged. A shotcrete reinforcement device is a device that uses compressed air to spray pre-mixed concrete material at high speed through a pipeline onto the area to be reinforced, forming a continuous concrete support layer. This device plays an irreplaceable role in the seepage prevention reinforcement of the soil between foundation pit piles.
[0003] Before pouring shotcrete, a pit of a certain depth is first dug between the piles. The pit is located between two adjacent piles. Then, a steel reinforcement frame is built inside the pit. The two piles are then poured together by shotcreting. If the distance between the two piles is large, the difficulty and uniformity of shotcreting will increase accordingly, which may lead to a decrease in the strength of the reinforcement device.
