本文系在浅水河道中利用导流方式,在桥墩部位填筑围堰成岛,在岛上进行混凝土灌注桩施工,再采用注浆固结方法,将河道地层中的淤泥层、砂层和粉细砂层固结,然后采用轻型井点降水方法,降低地下水至开挖基面,最后进行桩台桥墩施工。通过以上方法的运用表明:在浅水河道中桩基施工简便易行,桥墩深基坑开挖稳定可靠。 In this paper, the diversion method is used in the shallow water channel, the cofferdam is built at the bridge piers, the concrete pouring pile is constructed on the island, and then grouting and consolidation methods are used to separate the silt layer, sand layer and powder Fine sand layer consolidation, and then use light well point precipitation method to reduce groundwater to the excavation of the base surface, and finally the construction of pile piers. The application of the above method shows that the construction of pile foundation in shallow water channel is simple and easy, and the deep foundation pit excavation is stable and reliable.
