Description

Technical Field

[0001] The utility model relates to the field of building construction, in particular to a recyclable assembled inter-pile soil protection device. Background Art

[0002] At present, cast-in-place piles are a mature construction method in foundation pit support projects. They are widely used in foundation pit projects because of their simple construction process, easy quality control and small impact on the surrounding environment during construction. When the gap between adjacent cast-in-place piles is large or the site soil is heavy in sand, the soil between the piles is often easy to lose, especially in foundation pit projects in sandy areas without water-stop curtains, which poses a great safety hazard to the foundation pit support system. In order to avoid the loss of soil between cast-in-place piles and ensure the safety of the foundation pit support system, reliable soil protection measures between piles need to be taken.

[0003] At present, the existing pile soil protection between supporting piles without water-stop curtains adopts a sprayed concrete surface layer with built-in wire mesh or steel plate mesh. This measure is a non-recyclable structure and loses its use value after the foundation pit is backfilled, becoming an underground obstacle. This not only causes a waste of resources but also brings difficulties to the construction of surrounding underground projects. Utility Model Content
