Karst area foundation pit drainage treatment method in construction
The invention discloses a karst area foundation pit drainage treatment method in construction, which comprises the following steps of: arranging a water collecting well outside a foundation pit foundation range, introducing water flow at a water outlet into the water collecting well through a drainage blind ditch, installing a water pump in the water collecting well to drain accumulated water in time, and covering the top of the drainage blind ditch with a concrete prefabricated cover plate; a dry construction environment is provided for working procedures such as foundation concrete pouring; and after foundation pouring is completed, grouting is conducted through the pre-buried grouting steel pipe and the early-strength and high-strength underwater grouting material. The system and the method are simple in type and easy to operate, and compared with other methods such as direct grouting of the water outlet, the method is safer and more reliable, construction is convenient, and the construction period is shortened.
本发明公开了一种施工中的岩溶地区基坑排水处理方法，通过在基坑基础范围外设置集水井，通过排水盲沟将出水口水流引入集水井，在集水井中安装水泵将积水及时排走，同时排水盲沟顶部覆盖混凝土预制盖板，为基础混凝土浇筑等工序提供干燥施工环境；待基础浇筑完成，通过预埋灌浆钢管，采用早强高强型水下灌浆料进行灌浆。该系统及方法型式简单，易操作，相比其他方法，如直接对出水口进行灌浆，本方法更安全可靠，且方便施工，节省工期。
