Anti-seepage pressure relief construction method for underground engineering post-cast strip
The invention discloses an underground engineering post-cast strip anti-seepage pressure relief construction method, and relates to the technical field of underground engineering. Earthwork is excavated, inverted filter geotechnical cloth is laid, graded broken stone is filled, and a lower seepage ditch is formed; a guide drainage pipe is buried in the lower seepage ditch and connected to a pressure relief device; a pre-laid anti-sticking waterproof coiled material is fixed on the lower seepage ditch; reinforcing steel bars are installed on the anti-sticking waterproof coiled materials, and concrete is poured to form a bottom plate protection layer; after a waterproof layer is laid on the bottom plate protection layer, a waterproof protection layer is constructed, and an upper seepage ditch is formed in the middle; a guide drainage pipe is mounted in the upper sewer and connected to a pressure relief device; concrete is poured on the two sides of the post-cast strip, and the post-cast strip is divided through a fast-easy closing net and a fold line water-stop steel plate; concrete on the two sides of the post-cast strip is chiseled away and cleaned; embedding a valve control box and a control box reinforcing rib; water in the upper and lower seepage ditches is discharged through the pressure relief device, post-cast strip concrete is poured, and meanwhile the underground water pressure can be adjusted. The problem that leakage and floating resistance are prone to occurring before and after construction of the construction part of the post-cast strip is solved.
本发明公开了一种地下工程后浇带防渗泄压施工方法,涉及地下工程技术领域。开挖土方，铺设反滤土工布并填充级配碎石，形成下部渗沟；在下部渗沟中埋设导向排水管连接至泄压装置；在下部渗沟上固定预铺反粘防水卷材；在反粘防水卷材上安装钢筋，并浇筑混凝土形成底板保护层；在底板保护层上铺设防水层后施工防水保护层，并在中间形成上部渗沟；在上部渗沟安装导向排水管并连接至泄压装置；后浇带两侧浇筑混凝土，通过快易收口网和折线止水钢板分割；对后浇带的两侧混凝土凿除清理；埋设阀门控制盒和控制盒加强筋；通过泄压装置排除上下部渗水沟的水，浇筑后浇带混凝土，同时可以调整地下水压。本发明解决了解决后浇带的施工部位施工前后容易出现渗漏和抗浮的问题。
