AI Technical Summary
In existing technologies, it is difficult to effectively support the soil between cast-in-place piles, especially when the gaps between adjacent cast-in-place piles are large or the soil in the site is sandy. The soil between the piles is prone to loss, and the existing wire mesh shotcrete method lacks effective attachment points and cannot stabilize the soil between the piles.
The radial prefabricated connectors of the cast-in-place piles are connected to the outer reinforcement mesh. Multiple welding points are formed between the mesh hanging components and the outer reinforcement mesh. Positioning components are arranged on the outer reinforcement mesh to form a concrete anchor spray layer, which enhances the stability of the soil between the piles.
By combining multiple welding points and concrete anchor spraying layers, a more stable support structure is formed, effectively preventing soil loss between piles. It has the technical advantages of stable structure and simple configuration.
