Continuous protection structure of soil between filling piles

Abstract

The invention provides a continuous protection structure of soil between filling piles and belongs to the field of foundation pit support and underground engineering. The technical scheme is as follows: a suspended-net steel bar is pre-buried or planted in a filling pile body; one end of the suspended-net steel bar is arranged in the filling pile body; the other end of the suspended-net steel baris exposed outside the filling pile body; a steel bar net and a transverse steel bar are arranged outside the pile wall of the filling pile; the steel bar net is located between the pile wall and thetransverse steel bar; the suspended-net steel bar is in welded connection with the transverse steel bar; the steel bar net is connected with the transverse steel bar in a manner of binding through iron wires; a concrete surface layer is sprayed on the surface of the steel bar net. Through suspended-net spouting between the filling piles, the loss of the soil between the piles is avoided; the continuous protection measure of the soil between the piles is used for ensuring the safety of the foundation pit support system; the structure is convenient to construct and is safe and reliable.

Description

technical field [0001] The invention belongs to the field of foundation pit support and underground engineering, and can be widely used in foundation pit support and underground engineering for preventing soil loss between piles by utilizing the protective measures of hanging net and spraying grout between cast-in-place piles. Background technique [0002] At present, cast-in-situ piles are a mature construction method in domestic foundation pit support and underground engineering. It is widely used in foundation pit engineering because of its simple construction process, easy quality control and small impact on the surrounding environment during construction. There is generally a certain gap between adjacent cast-in-place piles, and the gap is determined according to factors such as force requirements, construction verticality deviation, and hole expansion. The soil is often easy to lose, especially in the foundation pit engineering in sandy soil areas without water-stop c...

There is generally a certain gap between adjacent cast-in-place piles, and the gap is determined according to factors such as force requirements, construction verticality deviation, and hole expansion. The soil is often easy to lose, especially in the foundation pit engineering in sandy soil areas without water-stop curtains, there is a large safety hazard of the foundation pit support system
