Deep foundation pit supporting structure and construction method thereof
The invention provides a deep foundation pit supporting structure and a construction method thereof. The deep foundation pit supporting structure comprises a first cement mixing pile fence, a steel sheet pile fence, a high-pressure jet grouting pile fence used as a waterproof curtain, a cast-in-place pile fence, a foundation pit inner support, a plurality of rows of second cement mixing pile rowsand a plurality of steel pipe piles. The supporting structure is convenient to construct, safe and effective, a foundation pit foundation can be reinforced, the foundation complexity is reduced, the foundation stability is ensured, and the excavation safety of the deep foundation pit is effectively controlled.
本发明提供了一种深基坑支护结构及其施工方法，其中深基坑支护结构包括第一水泥搅拌桩围挡、钢板桩围挡、用作防水帷幕的高压旋喷桩围挡、灌注桩围挡、基坑内支撑、若干排第二水泥搅拌桩排和若干钢管桩。本发明方便施工，安全有效且可对基坑地基进行加固，降低地基复杂程度，确保对地基稳固性，使深基坑开挖安全得到有效控制。
