Foam concrete soil karst cave grouting construction method
The invention provides a foam concrete soil karst cave grouting construction method, which relates to the technical field of soil karst cave construction, and comprises the following steps: measuring and determining the central position of a soil karst cave, and making a pile position arrangement diagram according to design requirements; pre-drilling holes are formed in the construction positions based on the pile position arrangement diagram; drilling is conducted in the pre-drilling position, and a pumping hole and an exhaust hole are manufactured; a pumping guide pipe is mounted in the pumping hole; an exhaust pipe is mounted in the exhaust hole; foam concrete is manufactured; the foam concrete is pumped into the soil karst cave through the pumping guide pipe until the whole soil karst cave is filled with the foam concrete, and pumping construction is finished; and after pumping construction is finished, the pumping guide pipe and the exhaust pipe are pulled out, and orifices of the pumping hole and the exhaust hole are blocked. According to the invention, the foam concrete is adopted to replace low-grade concrete, so that the setting time of the concrete is shortened, the flowing property of the concrete is improved, the pouring difficulty is reduced, the construction progress is accelerated, and the construction cost is reduced.
本发明提供了一种泡沫混凝土土溶洞注浆施工方法，涉及土溶洞施工技术领域，包括以下步骤：测量确定土溶洞中心位置，并根据设计要求制作桩位布置图；基于桩位布置图在施工位置布置预钻孔；在预钻孔位置钻孔，制得泵送孔及排气孔；在泵送孔内安装泵送导管；在排气孔内安装排气管；制作泡沫混凝土；将泡沫混凝土通过泵送导管泵送至土溶洞内，直至泡沫混凝土充填整个土溶洞，泵送施工结束；泵送施工结束后，起拔泵送导管及排气管，并将泵送孔及排气孔的孔口封堵。本发明中，采用泡沫混凝土替代低标号混凝土，缩短了混凝土的凝结时长，增加了混凝土的流动性能，减小了灌注难度，加快施工进度，降低施工成本。
