Foundation pit support construction method with external cement-soil mixing piles and anchor cable cast-in-place piles combined
The invention relates to the field of foundation pit supporting construction, in particular to a foundation pit supporting construction method combining external cement-soil mixing piles and anchor cable cast-in-place piles, which comprises the following steps: S1) constructing the cement-soil mixing piles; s2) constructing a cast-in-place concrete pile; s3) top beam construction; s4) pre-stressed duct forming and anchor cable construction; s5) spraying protection construction; s6) mounting a waist rail; s7) tensioning the anchor cable; according to the combined type foundation pit supporting structure, the waterproof curtain composed of the cement-soil mixing piles is externally arranged and matched with the prestressed anchor cable cast-in-place concrete piles on the inner side of the waterproof curtain, the combined type foundation pit supporting structure is formed, and the problems that in a sensitive construction site, foundation pit supporting is unstable, and construction is difficult are solved; foundation pit supporting can be effectively achieved, and the protection effect is remarkably improved.
本发明涉及属于基坑支护施工领域，尤其涉及一种外置水泥土搅拌桩与锚索灌注桩组合的基坑支护施工方法，包括以下步骤：S1)水泥土搅拌桩施工；S2)混凝土灌注桩施工；S3)冠梁施工；S4)预应力孔道成孔与锚索施工；S5)喷护施工；S6)腰梁安装；S7)锚索张拉；本发明将水泥土搅拌桩组成的止水帷幕外置，通过与止水帷幕内侧的预应力锚索混凝土灌注桩配合，形成组合式基坑支护结构，解决了敏感施工场地中基坑支护不稳定和难以施工的问题；能有效地实现基坑支护，并显著提高防护效果。
