Pile stabilizing structure and construction technology for offshore pouring type socketed pile steel casing in construction period
The invention relates to the technical field of wharf construction, and particularly discloses a pile stabilizing structure and a construction technology for an offshore cast-in-place socketed pile steel casing in the construction period. The pile stabilizing structure comprises a steel casing body, a guide pipe, a geotechnical bag, a cast-in-place pile structure section and a cast-in-place pile socketed section; the cast-in-place pile structure section is arranged in the steel casing body; the cast-in-place pile rock-socketed section is arranged at the lower end of the cast-in-place pile structure section, and the cast-in-place pile rock-socketed section penetrates through the surface layer strongly-weathered rock and is embedded in the moderately-weathered rock; an annular soil engineering bag is arranged on the outer side of the steel casing body, a sleeve hole is reserved in the top of the soil engineering bag, and a guide pipe is inserted into the top of the soil engineering bag. A filling material is arranged in the geotechnical bag, and the bottom of the geotechnical bag is located on the surface of the strongly weathered rock; the horizontal load resistance and the self-stability of the cast-in-place socketed pile steel casing in the construction period can be improved, meanwhile, materials can be recycled, and reliability and economical efficiency are achieved.
本发明涉及码头建设技术领域，具体公开了一种近海灌注型嵌岩桩钢护筒施工期稳桩结构及施工工艺，所述稳桩结构包括钢护筒本体、导管、土工袋、灌注桩结构段以及灌注桩嵌岩段，所述钢护筒本体底部镶嵌在海底表层的强风化岩中，所述灌注桩结构段设置在钢护筒本体内部；所述灌注桩嵌岩段设置在灌注桩结构段下端，且灌注桩嵌岩段从表层强风化岩中穿过，镶嵌在中风化岩中；所述钢护筒本体外侧设置有环形的土工袋，所述土工袋顶部留有套孔，导管插接在土工袋的顶部；所述土工袋内部设置有充填材料，所述土工袋底部处于强风化岩的表面；能够提高灌注型嵌岩桩钢护筒在施工期的抗水平荷载能力和自身稳定性，同时材料可循环利用，具备可靠性和经济性。
