Soft soil slope pile foundation inclination rectification structure and construction method
The invention belongs to the technical field of pile foundation engineering construction, and relates to a soft soil slope pile foundation inclination rectification structure and a construction method. The soft soil slope pile foundation inclination deviation rectifying structure comprises a deviation pile body, a pile top force generating device, a grating-gravel composite pile, a grouting pipe and a pile side reinforcing area, wherein the grating-gravel composite pile is composed of a grating pile casing and gravel. The grating-gravel composite pile is arranged in front of the pile, on one hand, the grating-gravel composite pile can serve as a stress release hole, and the passive side soil pressure in the deviation rectifying process is reduced through water pumping and drainage in the hole; and on the other hand, through grouting reinforcement, the soft soil characteristics are improved, the rigid gravel pile in front of the pile is formed, a pile side reinforcement area is combined, the bearing performance of the deviation pile is improved, the landslide thrust borne by the deviation pile is reduced, and then the reliability and stability of the deviation pile in the service period are improved. According to the method, the problems that traditional deviation rectifying measures are large in deviation rectifying difficulty and not thorough in deviation rectifying are solved, and good economical efficiency and feasibility are achieved.
本发明属于桩基工程施工技术领域，涉及一种软土斜坡桩基倾斜纠偏结构及施工方法。所述软土斜坡桩基倾斜纠偏结构包括偏位桩本体、桩顶发力装置、格栅‑碎石复合桩、注浆管和桩侧加固区，其中格栅‑碎石复合桩由格栅护筒和碎石组成。通过在桩前设置格栅‑碎石复合桩，一方面可以作为应力释放孔，且通过孔内抽排水，降低纠偏过程中被动侧土压力；另一方面通过注浆加固，改善软土特性，形成桩前刚性碎石桩，联合桩侧加固区，提高偏位桩承载性能，降低偏位桩承受的滑坡推力，进而增加偏位桩在服役期间的可靠性和稳定性。本发明克服了传统纠偏措施纠偏难度大、纠偏不彻底的难题，具有较好的经济型和可实施性。
