Rotary drilling rig and underground diaphragm wall rapid grooving construction method thereof
The invention relates to a rotary drilling rig. The drilling rig comprises a machine body module, a connecting transmission mechanism and a drilling mechanism, wherein the connecting transmission mechanism is connected with a machine base and comprises a supporting arm and a lifting arm, the supporting arm is in sliding connection with the lifting arm, the drilling mechanism is installed at the lower end of the connecting transmission mechanism, the drilling mechanism comprises a hydraulic motor, a reduction gearbox, a rotary sleeve table and three drill bits, and the rotary sleeve table is installed at the lower end of the supporting arm. The underground diaphragm wall rapid grooving construction method comprises the steps that the construction position of a ground diaphragm wall and the construction position of a guide wall are determined; a construction area is subjected to ground hardening; grooving construction is started at the construction position of the underground diaphragm wall, drilling construction is conducted through the rotary drilling rig to reach the footage, then construction is conducted through a trench cutter, the process is repeated in a reciprocating mode till the designed depth is reached, and residual is removed from a groove of the underground diaphragm wall; a reinforcement cage of the ground diaphragm wall is lowered; and concrete is poured. The working efficiency of the rotary drilling rig is high, and through the underground diaphragm wall rapid grooving construction method, the working efficiency of the trench cutter can be quickly improved and the cost can be greatly reduced.
本发明涉及一种旋挖钻，包括机身模块、连接传动机构、钻挖机构，连接传动机构与机座连接，连接传动机构包括支撑臂、升降臂，支撑臂与升降臂滑动连接，钻挖机构安装在连接传动机构的下端，钻挖机构包括液压马达、减速箱、旋转套台、三个钻头，旋转套台安装在支撑臂的下端。一种地连墙快速成槽施工方法：确定地连墙施工位置和导墙施工位置；对施工区域进行地面硬化；在地连墙施工位置处开始成槽施工，采用上述的旋挖钻进行钻孔施工达到进尺、然后采用双轮铣进行施工，往复循环直至达到设计深度，对地连墙槽进行清渣处理；下放地连墙的钢筋笼；浇筑混凝土。该旋挖钻工作效率高，该地连墙快速成槽施工方法可以快速提高双轮铣的工效且极大降低成本。
