Grooving construction method for annular underground diaphragm wall
The invention relates to the technical field of foundation pit underground diaphragm wall support construction, and discloses a grooving construction method for an annular underground diaphragm wall.The grooving construction method comprises the following steps that 1, the technical requirements and the quality standard are determined, a site is cleaned, and equipment is arranged to enter the site and installed and debugged; 2, I-shaped grooves are constructed, and after concrete of every two adjacent I-shaped grooves reaches certain strength, a II-shaped groove is constructed between every two adjacent I-shaped grooves, wherein the I-shaped grooves are bent by a certain angle, and the II-shaped grooves are flat and straight; 3, after a rotary drilling rig completes hole guiding, an underground diaphragm wall grab bucket or an MC96 groove milling machine is adopted for groove milling construction; 4, after grooving, groove hole perpendicularity detection is conducted; 5, a bottom frame platform is prefabricated according to the special design of an annular groove reinforcement cage, steel bars are laid on the bottom frame platform according to the steel bar variety, length and arrangement spacing of a design drawing, and corners with the same angle as the I-shaped grooves are arranged at the positions, corresponding to the bent positions of the I-shaped grooves, of the reinforcement cage; and 6, a pouring guide pipe is put down, and concrete is poured.
本发明涉及基坑地下连续墙支护施工的技术领域，公开了环形地下连续墙成槽施工方法，包括以下步骤：步骤1：明确技术要求、质量标准；清理场地，安排设备进场并安装调试；步骤2：施工Ⅰ型槽，当相邻两个Ⅰ型槽混凝土达到一定强度后，在相邻两个Ⅰ型槽之间施工Ⅱ型槽；Ⅰ型槽呈一定角度弯折布置，Ⅱ型槽呈平直状；步骤3：旋挖钻机引孔完毕后，采用地下连续墙抓斗或MC96铣槽机进行铣槽施工；步骤4：成槽后，进行槽孔垂直度检测；步骤5：按环形槽钢筋笼特殊设计预先制作底架平台，在底架平台上按设计图纸的钢筋品种、长度和排列间距，铺设钢筋，钢筋笼在对应于Ⅰ型槽弯折处设置与所述Ⅰ型槽呈相同角度的转角；步骤6：下入灌注导管，灌注混凝土。
