High-fill embankment structure and construction method
The invention discloses a high-fill embankment structure and a construction method. A plurality of layers of drainage blind ditches and geogrids among the layers of drainage blind ditches are arrangedin an embankment structure body from bottom to top; each layer of drainage blind ditch is a drainage blind ditch net with a grid structure formed by longitudinal blind ditches and transverse blind ditches which are intersected longitudinally and transversely, a side length of a grid is 12-15m, and a distance between the upper layer and the lower layer of the adjacent drainage blind ditches is notmore than 5m; each layer of geogrid is laid on a plane which is not less than 50cm away from the lower part of the upper drainage blind ditch layer in a full-plane manner; and foot protecting walls or drainage gullies are arranged on the two transverse sides of an embankment respectively. Accumulated water is drained by arranging longitudinal solid blind ditches and transverse solid blind ditches, settlement deformation of the high-fill embankment is prevented by arranging the geogrids, and engineering safety is improved; and compared with traditional measures such as adopting well-graded sand gravels, laying reinforcing meshes between layers, arranging load-reducing culverts and the like, the structure and the method have great economic advantages, and problems of excessive settlement and unsmooth embankment drainage can be effectively solved.
本发明公开了一种高填路堤结构及施工方法。路堤结构体中由下至上布置有多层排水盲沟和各层排水盲沟之间的土工格栅；各层排水盲沟由纵、横相交的纵向盲沟与横向盲沟构成网格结构的排水盲沟网，网格边长12～15m，相邻排水盲沟上下层之间的距离不大于5m；各层土工格栅全平面铺设布置于距离上部排水盲沟层下方不小于50cm的平面；路堤横向两侧分别设置护脚墙或排水冲沟；本发明通过设置纵、横向实芯盲沟排除积水，设置土工格栅防止高填路堤沉降变形，提高工程的安全性；对比传统采用级配良好的砂砾石，层间铺设钢筋网片，设置减荷涵洞等措施具有较大的经济优势，能有效解决沉降过大，路堤排水不畅的问题。
