Construction method for pier foundation located on landslide mass riverbed
The invention provides a construction method of a pier foundation located on a landslide mass riverbed, which comprises the following steps: S1, filling soil on the surface of the riverbed to form an island building platform, paving a layer of waterproof geotechnical cloth on the upstream slope surface of the island building platform, and placing a plurality of rock ballast bags on the waterproof geotechnical cloth; s2, GPS positioning is adopted, guide holes are punched in sequence in a jumping mode through a rotary drill, and steel sheet piles are inserted into the guide holes; the guide holes are filled with graded broken stones containing clay, and grouting reinforcement is conducted on the lower portion of the steel sheet pile; s3, earthwork of the foundation pit is excavated, a supporting frame is installed in the foundation pit, and the bottom of the foundation pit is sealed through waterproof concrete; and S4, hole digging piles are installed at the bottom of the foundation pit, a foundation body is installed on the tops of the hole digging piles, and pier construction is conducted on the top of the foundation body. The purposes of saving materials, preventing water return of the foundation pit and preventing collapse can be achieved.
本发明提供了一种位于滑坡体河床上的桥墩基础施工方法，包括以下步骤：S1、在河床表面进行填土形成筑岛平台，在筑岛平台的迎水坡面上铺一层防水土工布，在防水土工布上放置多个石渣袋；S2、采用GPS定位，通过旋挖钻分序跳打引孔，在引孔内插入钢板桩；打引孔内填含黏土的级配碎石，在钢板桩下部区进行注浆加固；S3、开挖基坑的土方，在基坑内安装支撑架，在基坑底部通过防水混凝土进行封底；S4、在基坑的底部安装挖孔桩，挖孔桩的顶部安装基础本体，在基础本体顶部进行桥墩施工。够达到节约材料、基坑不返水和防止坍塌的目的。
