Connection method for wall sections of ultra-deep anti-seepage wall
The invention discloses a connection method for the wall sections of an ultra-deep anti-seepage wall. The connection method for the wall sections of the ultra-deep anti-seepage wall comprises the steps of sequentially arranging downwards a plurality of joint pipes onto the end head of a slotted hole, and pulling out the joint pipes in a process of pouring concrete into the slotted hole, wherein the step of sequentially arranging downwards a plurality of joint pipes onto the end head of the slotted hole comprises the following steps: arranging a valve assembly and an adjustment assembly at oneend of a bottom pipe of each of the plurality of joint pipes; arranging downwards each bottom pipe with the valve assembly and the adjustment assembly at the bottom of the slotted hole, configuring one end of each of the valve assembly and the adjustment assembly to face the bottom of the hole, so that in the process of pouring the concrete, the adjustment assembly adjusts the opening degree of the valve assembly of the bottom pipe, and the phenomenon of pipe casting is prevented; and when the joint pipes are pulled out in the process of pouring the concrete, a pulling-out time for the joint pipes is controlled according to the components of the concrete and an environment temperature, so that the concrete cannot be adhered to the outer walls of the joint pipes. According to the method, the concrete cannot be adhered when the joint pipes are pulled out, a high hole-forming rate is achieved, the drilling amounts of the concrete joints are greatly reduced, the comprehensive working efficiency of the anti-seepage wall is increased, and the ultra-deep anti-seepage wall without wall breakage is formed.
本发明公开了一种超深防渗墙墙段连接方法，包括将多个接头管依次下设在槽孔端头及在槽孔内浇注混凝土的过程中起拔接头管的步骤，将多个接头管依次下设在槽孔端头包括：在多个接头管的底管一端设置活门组件以及调节组件；将带有活门组件及调节组件的底管下设在槽孔底部，设置活门组件以及调节组件的一端朝向孔底，以便浇注混凝土的过程中，调节组件调节底管活门组件的开度，防止铸管现象；在混凝土浇注过程中起拔接头管时，根据混凝土的组分、环境温度控制接头管的起拔时间，以便接头管外壁不会粘连混凝土。本发明的方法，接头管起拔时不会粘连混凝土，成孔率高，极大压缩混凝土接头钻凿量，提高防渗墙综合工效，并形成无断墙的超深防渗墙。
