Underground diaphragm wall anti-streaming structure under medium-thickness sand layer condition and construction method thereof
The invention discloses an underground diaphragm wall anti-streaming structure under the medium-thickness sand layer condition and a construction method thereof. The underground diaphragm wall anti-streaming structure comprises I-shaped steel installed at the two ends of a reinforcement cage, and anti-streaming iron sheets are connected to the side faces, close to a groove wall, of the I-shaped steel; and one ends of the anti-streaming iron sheets are fixedly connected with the I-shaped steel, and the other ends of the anti-streaming iron sheets extend in the direction opposite to the movement direction of concrete when the concrete is poured. The anti-streaming iron sheets are mounted on the outer sides of I-shaped steel wing plates, so that streaming of concrete can be blocked preliminarily; square holes are designed in the surface of each connector box, so that the connector box can enter a groove, buoyancy borne by the connector box during lowering is reduced, and lowering difficulty of the connector box is lowered; and connecting plates are arranged at the top of each connector box, and connecting holes are formed in the bottom of each connector box, so that splicing of multiple sections of connector boxes is facilitated.
本发明公开了一种中厚砂层条件下地连墙防绕流结构及其施工方法，包括安装在钢筋笼两端的工字钢，所述工字钢靠近槽壁的侧面位置连接有防绕流铁皮，所述防绕流铁皮的一端与工字钢固定连接、另外一端在浇筑混凝土时向着混凝土运动的反方向延伸；本发明通过在工字钢翼板外侧安装防绕流铁皮，能够初步阻挡混凝土的绕流；本发明的接头箱表面设计方孔，能够使接头箱进入槽内，减小接头箱下放时受到的浮力，降低接头箱的下放难度；本发明在接头箱顶部设置连接板及底部设置连接孔，便于多段接头箱的拼接。
