Pile bottom leveling and filling strength forming method for prefabricated assembly type pipe pile
The invention provides a pile bottom leveling and filling strength forming method for a prefabricated assembly type pipe pile. The pile bottom leveling and filling strength forming method comprises the following steps of (1) assembling a prefabricated tubular pile on site, lowering the prefabricated tubular pile to a certain distance away from the bottom of a hole, and temporarily fixing the prefabricated tubular pile through a hoop; (2) cleaning sediments at the bottom of the hole through slurry circulation; (3) after cleaning is completed, blending cement-mixed soil, and continuing to perform reverse circulation through the cement-mixed soil; (4) pouring underwater concrete; (5) loosening the hoop is, and grouting the pipe pile in place; (6) finely adjusting the verticality of the pipe pile; (7) performing maintaining. By means of the method, the pile bottom of the prefabricated pipe pile of a fabricated bridge can be horizontal, and besides, pile bottom strength and pile periphery strength meet the requirements.
本发明提供一种制装配式管桩桩底调平及填充强度形成方法，该方法包括如下步骤：(1)预制管桩现场拼装，下放到距离孔底一定距离，通过抱箍将预制管桩临时固定；(2)通过泥浆循环对孔底沉渣进行清理；(3)清理完成后调配水泥搅拌土，继续用水泥搅拌土进行反循环；(4)浇筑水下混凝土；(5)松抱箍，管桩坐浆到位；(6)微调管桩竖直度；(7)养护。通过上述方法，能够实现装配式桥梁预制管桩桩底水平，同时桩底和桩周强度满足要求。
