Foundation pit support supported by inclined piles and construction method of foundation pit support
The invention discloses a foundation pit support supported by inclined piles and a construction method of the foundation pit support, and aims to provide the foundation pit support which can complete construction of the inclined piles before excavation of a foundation pit, so that the foundation pit excavation operation is completed at a time under the condition of ensuring stable support of the foundation pit, the construction process steps are optimized, and the construction efficiency is improved. And the total construction period of the foundation pit is shortened. The foundation pit support construction method applying the inclined pile support sequentially comprises the following steps that A, foundation pit support pile construction is conducted, specifically, foundation pit support piles are constructed on the edge of a foundation pit; b, inclined pile construction: before excavation of the foundation pit, inclined cement mixing piles are constructed in a foundation pit soil layer on the inner side of a foundation pit fender post; thirdly, before the cement-soil mixing piles are hardened, inclined steel piles are inserted into the cement-soil mixing piles; and C, construction of a coping beam: before the foundation pit is excavated, concrete is poured along the upper ends of the foundation pit fender posts to form the coping beam, and the tops of the inclined steel piles are poured in the coping beam.
本发明公开了一种应用斜桩支撑的基坑围护及其施工方法，旨在提供一种能够在基坑开挖前完成斜桩的施工，从而实现在保证基坑支撑稳定的情况下，一次性完成基坑挖土作业，从而优化施工工艺步骤，加快基坑总施工周期的应用斜桩支撑的基坑围护及其施工方法。应用斜桩支撑的基坑围护施工方法，依次包括以下步骤，A，基坑围护桩施工，在基坑的边缘施工基坑围护桩；B，斜桩施工，在基坑开挖前，在基坑围护桩内侧的基坑土层中施工倾斜分布的水泥土搅拌桩；接着，在水泥土搅拌桩硬化之前，在水泥土搅拌桩内插入斜钢桩；C，压顶梁施工，在基坑开挖前，沿基坑围护桩的上端浇筑混凝土形成压顶梁，斜钢桩的顶部浇筑在压顶梁内。
