Construction method applicable to overflow prevention of over-grouting parts of underground diaphragm walls with various thicknesses
The invention relates to an anti-overflow construction method applicable to over-grouting parts of underground diaphragm walls with various thicknesses, and aims to prevent concrete from overflowing to a position close to a next to-be-constructed groove section to be difficult to form a groove, which comprises the following steps of: hoisting and lowering a reinforcement cage of the underground diaphragm wall in place after the groove section of the underground diaphragm wall is excavated; a first component and a second component are installed in the grooves and tightly attached to the guide walls on the two sides respectively, the bottoms of the components are clamped into the I-shaped steel, and after the first component and the second component are clamped into the I-shaped steel and installed, a third component is inserted into the inner side grooves of the first component and the second component. The method can prevent the concrete at the over-grouting part from overflowing to the adjacent groove section, and is simple in component and easy and convenient to operate. And the device can be suitable for underground diaphragm walls with different thicknesses, and the effect of effectively preventing overflow can be achieved.
本发明涉及一种适用多种厚度地下连续墙超灌部位防溢流的施工方法，为防止混凝土溢流至临近下一幅待施工槽段成槽困难，其步骤为：待地下连续墙槽段开挖完成后，将地下连续墙钢筋笼吊装下放到位，并于槽内安装构件一和构件二并分别紧贴两侧导墙，构件底部卡进工字钢上，待构件一、二卡进工字钢安装完毕后，在构件一、二内侧槽中插入构件三。通过该方法可阻止超灌部位混凝土溢流至临近槽段，构件简单，操作简便。且可适用于不同厚度的地下连续墙，能达到有效防止溢流的作用。
