Construction method of diaphragm wall under complex geological conditions
The invention is suitable for the technical field of buildings, and provides an underground diaphragm wall construction method under complex geological conditions, which comprises the following processes: construction preparation, surveying and lofting, guide wall manufacturing, grooving construction, reinforcement cage manufacturing and hoisting, wall section joint construction and concrete pouring. Wherein during grooving construction, a combined construction technology of a rotary excavating drill, a grooving machine, a double-wheel milling machine and a punching drill is adopted for carrying out whole-process interpenetrating construction, a theodolite is used for carrying out perpendicularity tracking observation in the grooving process, the perpendicularity is controlled according to the perpendicularity deviation of grooving equipment and a perpendicularity displayer and an automatic deviation correcting device of the grooving machine, and before grooving, the perpendicularity of the grooving machine is controlled according to the perpendicularity displayer and the automatic deviation correcting device of the grooving machine. And the shaped muck box is welded according to the actual situation on site. In the grooving process, a mechanical automatic deviation correcting device is used for conducting perpendicularity tracking observation, and the perpendicularity precision is high. Compared with a traditional construction method, the combined construction technology of the rotary excavating drill, the grooving machine, the double-wheel milling and the punching drill is adopted, and the problem that grooving cannot be conducted when a single grooving machine is adopted and encounters a hard rock stratum is solved.
本发明适用于建筑技术领域，提供了一种复杂地质条件下地连墙施工工法，该工法包括下列流程：施工准备、测量放样、导墙制作、成槽施工、钢筋笼制作和吊放、墙段接头施工以及混凝土浇筑。其中，在成槽施工时，采用旋挖钻+成槽机+双轮铣+冲孔钻组合施工技术进行全工序穿插施工，成槽过程中利用经纬仪进行垂直度跟踪观测，根据成槽设备的垂直度偏差，根据成槽机的垂直度显示仪和自动纠偏装置控制垂直度，成槽前，根据现场实际情况焊制定型化渣土箱。成槽过程中利用机械自动纠偏装置进行垂直度跟踪观测，垂直度精度高。采用旋挖钻+成槽机+双轮铣+冲孔钻组合施工技术，与传统的施工方法相比，解决了采用单一的成槽机，遇坚硬岩层无法成槽的问题。
