Anchor cable and recyclable steel pile combined foundation pit support structure and construction method thereof
The invention belongs to an anchor cable and recyclable steel pile combined foundation pit support structure and a construction method thereof in foundation pit support engineering. The anchor cable and recyclable steel pile combined foundation pit support structure adopts the technical scheme that a foundation pit excavation area is arranged on one side of a cement and soil mixing pile, a sectionsteel pile, a steel sheet pile, a steel beam, an inclined steel cable, anchor cables and a jet grouting pile are arranged in the cement and soil mixing pile, the section steel pile is located near the foundation pit excavation area, and the steel sheet pile is located away from the foundation pit excavation area; the steel beam is connected with the section steel pile and the steel sheet pile, and the jet grouting pile is located on the lower part of the steel sheet pile; the inclined steel cable bypasses a pile body of the steel sheet pile downwards and is clamped at the pile body, and bothends are anchored to the outer side of the top of the section steel pile upwards; and the anchor cables are arranged in the steel sheet pile, the tops of the anchor cables are anchored to the top of the steel sheet pile, and the bottoms of the anchor cables are anchored to an anchoring device which is arranged in the jet grouting pile. Steel in the foundation pit support structure can be completely recycled and reused.
本发明属于基坑支护工程中的锚索与可回收钢桩组合的基坑支护结构及其施工方法，技术方案为：种锚索与可回收钢桩组合的基坑支护结构，水泥土搅拌桩的一侧为基坑开挖区，水泥土搅拌桩内设置型钢桩、钢板桩，钢梁、斜钢索、锚索和旋喷桩；型钢桩位于靠近基坑开挖侧，钢板桩位于远离基坑开挖侧；钢梁连接型钢桩和钢板桩，旋喷桩位于钢板桩的下部；斜钢索向下绕过钢板桩的桩身，并卡在桩身位置，两端向上与型钢桩的顶部外侧锚固；钢板桩内设置锚索，锚索的顶部与钢板桩的顶部锚固，锚索的底部与设在旋喷桩内的锚固装置锚固。其中基坑支护结构中钢材可完整回收重复利用。
