Pile-supported embankment with large-area round pile caps of cross beams and construction method of pile-supported embankment
The invention relates to a pile-supported embankment with large-area round pile caps of cross beams and a construction method of the pile-supported embankment. Firstly, an embankment foundation is constructed, and cylindrical piles are driven into the foundation in an array mode; connecting beams are mounted on column bodies close to the upper ends of the cylindrical piles, so that the multiple groups of cylindrical piles are connected into a whole; a pile cap is mounted at the upper end of the cylindrical pile; a first reinforcing piece is installed between the pile cap and the cylindrical pile; a second reinforcing piece is mounted between the pile cap and the connecting beam; and a mattress layer is laid at the upper ends of the cylindrical piles, so that the pile caps are embedded into the mattress layer. According to the construction method, the anti-settling capacity of the embankment is improved, lateral displacement of a single pile is restrained, when the foundation is affected by seepage of rainwater or underground water, damage caused by too large horizontal displacement of the whole cylindrical pile is prevented, the service life of the pile foundation structure is prolonged, and the construction method is suitable for large-scale popularization and application. The first reinforcing piece and the second reinforcing piece can enhance the compressive damage resistance of the pile cap, and the situation that the pile cap is crushed and crushed due to the fact that no support exists below the pile cap is avoided.
本发明涉及一种交叉梁大面积圆桩帽的桩承式路堤及其施工方法，首先施工出路堤地基，在地基上阵列式打入圆柱桩；靠近圆柱桩的上端柱身上安装连接梁，使得多组圆柱桩连接为一体；在圆柱桩的上端安装桩帽；在桩帽与圆柱桩之间安装第一加强件；桩帽与连接梁之间安装第二加强件；在圆柱桩的上端铺设褥垫层，使得桩帽嵌入在褥垫层内。在所述褥垫层上方铺设路基层，在路基层上铺设路面层，该施工方法提高了路堤的抗沉降能力，并约束了单桩的侧向位移，使地基受到雨水或地下水的渗流影响时，防止圆柱桩整体因水平位移过大导致的破坏，增加了桩基础结构的使用寿命，第一加强件和第二加强件可增强桩帽的抗压破坏能力，防止由于桩帽下无支撑导致桩帽压坏、压碎。
