Grooving method for underground diaphragm wall
The invention relates to a grooving method for an underground diaphragm wall. The grooving method comprises the steps that a groove body is grabbed and dug in a groove section of a constructed guide wall, and slurry is introduced into the groove body; when the groove body grabs and digs a rock stratum, a grabbing and digging guide hole with a preset length is drilled; and the rock stratum with thegrabbing and digging guide hole is grabbed and dug to a preset depth, and the grabbed and dug rock is removed to form the groove section of the underground diaphragm wall. When the underground diaphragm wall is grooved to the rock stratum, a rotary drilling machine is adopted to drill the grabbing and digging guide hole, and finally the rock stratum with the grabbing and digging guide hole is grabbed by a grab machine, so that the construction capacity of various common machines is fully utilized, the use of machines with high cost is avoided, the construction cost is reduced, and meanwhile,the operation capacity of the grab machine is improved, and the construction progress and quality of grooving are guaranteed; and the rotary drilling machine is adopted to drill the grabbing and digging guide hole, so that the vibration generated when a drilling machine or a punching machine is adopted for drilling is avoided, and the influence of punching or drilling vibration on the surroundingenvironment is reduced.
本发明涉及一种地下连续墙的成槽方法，包括在施工完导墙的槽段内抓挖槽体，并在所述槽体内引入泥浆；在所述槽体抓挖到岩层时，钻设预设长度的抓挖引孔；抓挖具有所述抓挖引孔的岩层到预设深度，将抓挖出的岩石清除，形成地下连续墙槽段。在地下连续墙成槽到岩层时，采用旋挖机钻设抓挖引孔，最后再通过抓斗机抓具有抓挖引孔的岩层，充分利用各类常用机械的施工能力，避免了采用成本较高的机械，降低了施工成本，同时也提高了抓斗机的作业能力，保证了成槽的施工进度和质量；采用的旋挖机进行抓挖引孔的钻设，避免了采用钻孔机或者冲孔机钻孔时产生的震动，降低了冲孔或者钻孔震动对周边环境的影响。
