Plateau composite geological bridge pile foundation steel casing follow-up construction method
The invention relates to the technical field of bridge pile foundation construction, in particular to a plateau composite geological bridge pile foundation steel casing follow-up construction method. The method comprises the following steps that S1, a site is leveled, machines enter the site to be installed and debugged, water, electricity and road tee joints are installed, and construction preparation conditions are met; S2, a positioning hole is measured; S3, a main steel casing is embedded in the position of the pile foundation, and the shape and the size of the steel casing meet the design requirements; S4, a drilling machine is installed, the drilling machine is stably installed on one side of the drill hole, and the drilling machine supports the sole timber and does not press the orifice steel casing; S5, follow-up steel casings are installed step by step; S6, a hole detector is used for hole detection during hole detection drilling; S7, hole cleaning: after hole inspection is completed, hole cleaning is carried out immediately; S8, a reinforcement cage is mounted; and S9, underwater concrete is poured. The construction method provided by the invention is feasible, safe, controllable, economical and applicable. The method is mainly applied to the plateau composite geological bridge pile foundation steel casing follow-up construction.
本发明涉及桥梁桩基施工技术领域，更具体而言，涉及一种高原复合地质桥梁桩基钢护筒跟进法施工方法。包括以下步骤：S1、平整场地，机械进场安装调试，水、电、路三通，达到施工准备条件；S2、测定位孔；S3、在桩基位置埋设主钢护筒，钢护筒外型、尺寸符合设计要求；S4、安装钻机，钻机稳定地安装在钻孔的一侧，钻机支承垫木不得压在孔口钢护筒上；S5、逐级安装跟进钢护筒；S6、验孔钻进时应用检孔器检孔；S7、清孔：检孔完成后，立即进行清孔；S8、钢筋笼安装；S9、浇筑水下混凝土。本发明提供了一种切实可行、安全可控、经济适用的施工方法。本发明主要应用于高原复合地质桥梁桩基钢护筒跟进法施工方面。
