Construction method of compression-resistant and pulling-resistant composite foundation structure capable of controlling settlement
The invention discloses a settlement-controlled anti-compression and anti-pulling composite foundation structure construction method which comprises the following steps: S1, positioning the position of an anti-pulling pile, and drilling in an original stratum to a designed depth; s2, after the holes are cleaned, plain concrete piles and uplift concrete piles are arranged; s3, the plain concrete piles and the uplift concrete piles are detected and tested; s4, after the test is qualified, paving a gravel mattress on the surface of the original stratum; s5, a cushion layer is constructed above the gravel mattress, and a water-resistant plate is arranged on the cushion layer; and S6, an anchor cable drawing groove is formed in the portion, above the uplift concrete pile, of the water-resistant plate, after the strength of the water-resistant plate reaches the designed strength, the non-sticky anchor cable is tensioned, after the designed prestress value is reached, a lock is installed, the anchor cable is locked, and anchor cable end sealing is conducted on the anchor cable drawing groove. The CFG pile has the advantages that on the basis of an original CFG pile, the non-sticky anchor cables are connected with the compression-resistant steel plates, so that the vertical bearing capacity is exerted, and meanwhile, the pulling resistance of the CFG pile is exerted.
本发明公开了一种控制沉降的抗压抗拔复合地基结构施工方法，包括以下步骤，S1.定位抗拔桩位置，在原始地层内钻孔至设计深度；S2.清理孔后，设置素混凝土桩和抗拔混凝土桩；S3.对素混凝土桩及抗拔混凝土桩进行检测试验；S4.试验合格后，在原始地层表面铺设碎石褥垫；S5.在碎石褥垫上方施工垫层，并在垫层上设置抗水板；S6.在抗拔混凝土桩的上方的抗水板上设置锚索拉拔槽，待抗水板强度达到设计强度后，对无粘锚索进行张拉作业，达到设计预应力值后安装锁具，锁定锚索，并对锚索拉拔槽进行锚索端头封锚。其优点在于，在原CFG桩的基础上，采用无粘锚索与抗压钢板连接，发挥竖向承载力的同时，让其抗拔力得以发挥作用。
