Stiff cement soil supporting row pile composite supporting system and construction method thereof
The invention relates to a stiff cement soil supporting row pile composite supporting system and a construction method thereof. The construction method comprises the steps of setting out and positioning a plurality of first pile positions of a plurality of cement soil mixing piles for forming a waterproof curtain in a surrounding mode, determining a plurality of second pile positions of to-be-constructed concrete cast-in-place piles in the first pile positions, constructing a plurality of cement soil mixing piles one by one in the plurality of first pile positions, and coaxially inserting the concrete cast-in-place piles into the cement soil mixing piles in the second pile positions when the cement soil mixing piles in the second pile positions are constructed and meet the strength requirement in the one-by-one construction process, wherein the pile diameter of the concrete cast-in-place piles is smaller than that of the cement soil mixing pile. The composite supporting system has the advantages of high shearing resistance and bearing capacity, good safety performance, high stability, short construction period and low construction cost and is suitable for projects with narrow sites and high building surrounding environment requirements, and a water stop effect can be effectively achieved during oil retaining.
本发明涉及一种劲性水泥土支护排桩复合支护体系及其施工方法，该施工方法包括步骤：放线定位出围设形成止水帷幕的多根水泥土搅拌桩的多个第一桩位，于多个该第一桩位中确定待施工混凝土灌注桩的多个第二桩位；于多个该第一桩位处逐根施工多根该水泥土搅拌桩，并且在逐根施工过程中，每当位于该第二桩位处的水泥土搅拌桩施工完毕并达到强度要求时，于该第二桩位处的水泥土搅拌桩内同轴插入混凝土灌注桩，其中，该混凝土灌注桩的桩径小于该水泥土搅拌桩的桩径。本发明复合支护体系具有较强的抗剪切力及承载力，在挡土的同时可有效地起到止水作用，安全性能好，稳定性强，施工工期短且施工成本低，适用于场地狭小、建筑物周边环境要求高的工程。
