Round deep foundation pit supporting method
The invention relates to the field of foundation pit supporting technologies, in particular to a circular deep foundation pit supporting method which comprises the following steps: S1, supporting surrounding piles in rows; s2, carrying out earth excavation for the first time; s3, crown beam construction; s4, earth excavation for the second time; s5, constructing a first inner ring beam; s6, carrying out earth excavation for the Nth time; s7, the (N-1) th inner ring beam is constructed; s8, carrying out earth excavation for the last time; s9, constructing a foundation structure; and S10, earthwork backfilling is conducted. The construction method has the advantages that the support piles are constructed on the ground, the piles are empty at the upper part, the cost is saved, and the construction is convenient; a plurality of inner ring beams are used for forming an inner reinforcing ring on a cylinder wall of the support pile, so that the rigidity is increased, and a dual supporting and reinforcing effect is achieved; the circular deep foundation pit is particularly suitable for underground circular structure buildings, the top beams and the inner ring beams jointly play a role in inner supporting, reinforcing and pressure resisting, the top beams and the supporting piles form an integral ribbing structure form, and the purpose of safely and efficiently constructing the circular deep foundation pit is achieved.
本发明涉及基坑支护技术的领域，尤其是涉及一种圆形深基坑支护方法，其包括以下步骤：S1、周围排桩支护；S2、第一次土方开挖；S3、冠梁施工；S4、第二次土方开挖；S5、第一道内环梁施工；S6、第N次土方开挖；S7、第N‑1道内环梁施工；S8、最后一次土方开挖；S9、基础结构施工；S10、土方回填。采用上述施工方法的优势是，地面上进行支护桩施工，上部空桩，节约成本，施工方便；多道内环梁对支护桩形成筒壁进行内加强圈，增大刚度，起到双重支撑加强作用；特别适用于地下圆形结构建筑，冠梁与内环梁共同起到内支撑加强抗压作用，与支护桩形成整体加肋结构形式，实现安全高效施工圆形深基坑的目的。
