摘要
结合工程实际,介绍了在地基层灰岩破裂处发生大量渗水的项目施工中,采用的一种新型的混凝土圆筒封闭渗水点后浇筑阻渗防水混凝土及数控自动降排水处理施工技术。即通过混凝土圆筒定向封闭渗水点后,再浇筑防水混凝土阻渗,同时利用浮球液位控制器辅助检测水位进行降排水,实现了高效智能的地下水处理,解决了破碎岩石地质条件下的基坑施工降水困难问题,取得了良好的社会效益和经济效益。
Combined with the engineering practice,this paper introduces the construction technology of a new type of impermeable waterproof concrete and numerical control automatic drainage after sealing the seepage point by a new type of concrete cylinder used in the construction of projects with a large amount of water seepage at the fractured limestone base.After directional sealing of seepage point through concrete cylinder,the waterproof concrete is poured to prevent seepage.At the same time,the ball float level controller is used to assist in detecting the water level for drainage,and thus efficient and intelligent groundwater treatment are realized and the difficult problem of dewatering in foundation pit construction is solved under the condition of broken rock geology and good social and economic benefits are achieved.
