Bottom plate post-cast strip leakage well casing plugging structure and construction method
The invention discloses a bottom plate post-cast strip leakage well casing plugging structure and a construction method, and the method comprises the following steps: finding a leakage point of a post-cast strip, and breaking and removing concrete at the leakage position; pumping water in the chiseling area, installing a vacuum downcast pipe in the chiseling area, filling graded broken stones in the vacuum downcast pipe when the water level drops below the installation position of the steel cover plate, and installing the steel cover plate in the vacuum downcast pipe; a bottom plate post-cast strip leakage point is found, a damaged waterproof layer is repaired, and then expansive concrete is poured in the chiseling area and cured; in the expansive concrete curing period, water is kept flowing outwards through the water outlet pipe and the grouting pipe, grouting is conducted in the vacuum downcast pipe through the grouting pipe when downcast is allowed to be stopped after curing is finished, and the grouting is stopped and the valve is closed when the vacuum downcast pipe is full; and cleaning the upper part of the steel cover plate in the vacuum downcast pipe, pouring hard concrete on the upper part of the steel cover plate, and curing. According to the method, the water leakage area of the post-cast strip under the geological conditions of high permeability and high water pressure can be rapidly repaired.
本发明公开了一种底板后浇带渗漏井管封堵结构及施工方法，方法如下找到后浇带的渗漏点，将渗漏处的混凝土破除；对剔凿区域进行抽水，并在剔凿区域内安装真空降水管，当水位降至钢盖板安装位置以下时，在真空降水管内填充级配碎石，并将钢盖板安装在真空降水管内；寻找底板后浇带渗漏点，对破损的防水层进行修补，然后在剔凿区域浇筑膨胀混凝土并养护；在膨胀混凝土养护期间，通过出水管和注浆管保持水外流，待养护结束后允许停止降水时，通过注浆管向真空降水管内注浆，注满时停止并关闭阀门；将真空降水管内于钢盖板上部清理干净，在钢盖板上部浇筑干硬性混凝土并养护。本申请能够快速修补高渗透性、高水压地质条件下后浇带渗漏水的区域。
