Continuous protection structure of soil between filling piles

Abstract

The invention belongs to the field of foundation pit support and underground engineering and is a continuous protection structure for soil between cast-in-situ piles. The technical scheme is: pre-buried or planted hanging net reinforcement in the cast-in-situ pile body, one end of the net-hanging steel bar is placed inside the cast-in-place pile body, and the other end is exposed outside the cast-in-place pile body; , the reinforcement mesh is located between the pile wall and the transverse reinforcement, the mesh reinforcement and the transverse reinforcement are welded and connected, the reinforcement mesh and the transverse reinforcement are connected by wire binding, and the concrete surface is sprayed on the surface of the reinforcement mesh. The invention avoids the loss of soil between the piles through the hanging net spraying grout between the cast-in-situ piles, and utilizes continuous protective measures for the soil between the piles to ensure the safety of the foundation pit support system. The structure is convenient in construction, 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...

Problems solved by technology

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
