Rapid construction method for underground diaphragm wall in complex stratum
The invention discloses a rapid construction method for an underground diaphragm wall in a complex stratum. The rapid construction method comprises the following steps: measurement lofting is carried out on a construction position, and geological conditions at the construction position is detected; a first width rock groove section and a second width groove section are constructed on the construction position in sequence through a hydraulic grab bucket and a percussion drill of a trenching machine, and then a third rock-free groove section is constructed through the hydraulic grab bucket; after the groove sections are constructed, hole repairing is conducted on the groove sections through a square hammer, and primary groove cleaning treatment is conducted on the first width rock groove section and the second width rock groove section; after groove cleaning is completed, a reinforcement cage and a connector box are hoisted to the groove sections, a concrete guide pipe is placed, and secondary groove cleaning treatment is conducted on the groove sections; concrete pouring is conducted on the groove sections to form an underground diaphragm wall body, and then the connector box is pulled out; and the steps are repeated, and underground diaphragm wall construction is completed. The method is convenient to construct and high in efficiency, a specific combination construction process is appointed for the complex stratum with soil and rock combination and soft upper part and hard lower part, and the construction effect is greatly improved.
本发明公开了一种复杂地层地下连续墙快速施工方法，包括以下步骤：对施工位置进行测量放样，检测施工位置处的地质条件；通过成槽机的液压抓斗和冲击钻对施工位置分序施作第一幅有岩槽段和第二有幅槽段，随后再通过液压抓斗施作第三无岩槽段；槽段施作完成后，通过方锤对槽段进行修孔，并对第一幅有岩槽段和第二幅有岩槽段进行一次清槽处理；清槽完成后，吊装钢筋笼和接头箱至槽段处，并放置砼导管，并对槽段进行二次清槽处理；向槽段处进行混凝土浇筑形成地连墙体，随后拔出接头箱；重复上述步骤，完成地下连续墙施工；该方法施工便捷，效率高，针对土岩结合、上软下硬的复杂地层指定特有的组合施工工艺，大大提高了施工效果。
