Soft and hard geological deep foundation pit drilling secant pile supporting construction method
The invention discloses a soft and hard geological deep foundation pit drilling secant pile supporting construction method, and relates to the technical field of underground engineering. Moving the secant pile machine in place; the center of a pipe holding device of the secant pile machine is correspondingly positioned in the center of the hole site in the guide wall; piping is conducted; the height of the sleeve is within the drill bit lifting range of the rotary drilling rig; a secant pile machine is used for drilling a soil layer to form a hole; a rotary drilling rig is used for drilling the moderately weathered rock stratum to form holes; moving away the grab bucket after the sleeve enters the moderately weathered rock stratum, and forming a hole by using a rotary drilling rig; the angles of the plurality of bucket teeth cut into the intermediary weathered rock stratum are different, and the angles of the bucket teeth cut into the intermediary weathered rock stratum are 20-60 degrees; a reinforcement cage is manufactured and hoisted; the reinforcement cage is square or round, and the side face of the square reinforcement cage is fixedly connected with a positioning part. Placing a conduit; and pouring concrete. According to the soft and hard geological deep foundation pit drilling secant pile supporting construction method, the construction progress can be accelerated, the construction period can be shortened, and the construction cost can be reduced.
本申请公开一种软硬地质深基坑钻孔咬合桩支护施工方法，涉及地下工程技术领域，包括以下步骤：施工导墙；移动咬合桩机就位；使咬合桩机的抱管器中心对应定位于导墙上的孔位的中心；配管；使套管高度在旋挖钻机的钻头提升范围之内；使用咬合桩机向土层钻进成孔；使用旋挖钻机向中风化岩层钻进成孔；套管进入中风化岩层后移走抓斗，使用旋挖钻机成孔；多个斗齿切入中风化岩层的角度各不相同，斗齿切入中风化岩层的角度为20°～60°；制作并吊装钢筋笼；钢筋笼为方形或圆形，在方形钢筋笼的侧面固定连接定位部；安放导管；灌注混凝土。本说明书所提供的软硬地质深基坑钻孔咬合桩支护施工方法，能加快施工进度，减少施工周期，且能降低施工费用。
