Static drilling root planting pile capable of improving bearing capacity through secondary grouting and construction method of static drilling root planting pile
The invention discloses a static drilling rooted pile capable of improving bearing capacity through secondary grouting and a construction method of the static drilling rooted pile. The static drilling rooted pile comprises a prefabricated pile body and pile periphery cemented soil. The precast pile body is tubular, grouting pipes comprising grouting branch pipes and a grouting main pipe are arranged in the precast pile body, and preformed holes are formed in the pipe wall corresponding to the grouting branch pipes; a plurality of layers of grouting branch pipes are arranged on the outer wall of the grouting main pipe in the axial direction; each grouting branch pipe is obliquely arranged in the radius direction of the position where the grouting branch pipe is located, and obliquely extends downwards from the grouting main pipe to the pipe wall position of the prefabricated pile body; each preformed hole is matched with the corresponding grouting branch pipe and used for allowing the corresponding grouting branch pipe to penetrate through; during construction, cement soil is output from the corresponding preformed hole through each grouting branch pipe and breaks down the cement soil around the pile at the corresponding position, and a plurality of protruding cement soil reinforcing bodies protruding out of the outer wall of the cement soil around the pile are formed on the outer side of the cement soil around the pile. The bearing capacity of the static drilling root planting pile is improved, technical progress and industry development are promoted, and good economic and social benefits are achieved.
本发明公开了利用二次注浆提高承载力的静钻根植桩及其施工方法，包括预制桩体和桩周水泥土；预制桩体呈管状，内部设置包括注浆支管和注浆干管的注浆管，管壁对应每一注浆支管均设有预留孔；注浆干管外壁沿轴向设有多层注浆支管；每一注浆支管均与所在位置的半径方向倾斜设置，从注浆干管向预制桩体的管壁位置倾斜向下延伸；每一预留孔均与相应的注浆支管相配，用于穿设相应的注浆支管；施工时，将水泥土经每一注浆支管从相应的预留孔输出，并击穿相应位置的桩周水泥土，在桩周水泥土外侧形成多个凸出桩周水泥土外壁的凸起水泥土加固体。本发明高了静钻根植桩的承载力，推动技术进步、行业发展，具有良好的经济和社会效益。
