Pier foundation pit filling structure of L-shaped foam concrete blocks and construction method
The invention provides a pier foundation pit filling structure of L-shaped foam concrete blocks and a construction method, and belongs to the technical field of road and bridge engineering construction.The pier foundation pit filling structure comprises a foundation pit, at least one pile foundation, a bearing platform, a pier and a filling structure; at least one pile foundation is arranged in the foundation pit; the bottom surface of the bearing platform is connected with the top surface of the pile foundation; the pier is connected with the top surface of the bearing platform; according to the device, the L-shaped foam concrete blocks are filled in an embedding and extruding layered cross overlapping mode, and the foundation pit is filled in combination with a cast-in-place foam concrete joint filling mode, so that the foundation pit filler strength and integrity between a bearing platform group and a bridge pier group are enhanced, and the pressure of foundation pit backfill soil is reduced through the characteristics of foam concrete; and the problems of pier settlement and uneven settlement among pier groups are reduced.
本发明提供了一种L型泡沫混凝土砌块的桥墩基坑填筑结构及施工方法，所属道路桥梁工程施工技术领域，包括：基坑、至少一个桩基、承台、桥墩和填充结构；至少一个桩基设置在基坑内；承台的底面与桩基的顶面相连接；桥墩与承台的顶面相连；该装置通过嵌挤分层交叉重叠的方法填筑L型泡沫混凝土砌块并结合现浇泡沫混凝土填缝的方法填筑基坑，从而加强了承台群及桥墩群之间的基坑填料强度及一体性，并利用泡沫混凝土的特性降低了基坑回填土的压力，减少了桥墩沉降及桥墩群间的不均匀沉降的问题。
