Layered filling method for light combined roadbed of abrupt slope section
The invention discloses a layered filling method for a light combined roadbed of an abrupt slope section. The layered filling method comprises the steps that construction of a protection wall concretefoundation is completed on a foundation pit; an anti-sliding anchoring part is inserted into the abrupt slope section; a first protection wall single layer is constructed on the protection wall concrete foundation, a first foam light soil single layer is poured between the abrupt slope section and the first protection wall single layer to form a first filling roadbed, a middle geogrid is paved onthe surface of the first filling roadbed, and the steps are repeated until a top filling roadbed is formed; a top layer geogrid is laid on the surface of the top layer filling roadbed to form the light combined roadbed; and an HDPE impermeable geomembrane is laid on the top geogrid. In the embodiment of the invention, the layered filling method has the advantages of simple structure, conveniencein construction and high overall stability, differential settlement can be effectively reduced, and the layered filling method has good practicability.
本发明公开了一种陡坡路段轻质组合式路基的分层填筑方法，分层填筑方法包括：在基坑上完成保护壁混凝土基础的施工；在陡坡路段上插入抗滑锚固件；在保护壁混凝土基础上砌筑第一层保护壁单层，在陡坡路段与第一层保护壁单层之间浇注第一层泡沫轻质土单层，形成第一层填筑路基，并在第一层填筑路基的表面铺设中间土工格栅，重复上述步骤，直至形成顶层填筑路基，并在顶层填筑路基的表面铺设顶层土工格栅，形成轻质组合式路基；在顶层土工格栅上铺设HDPE防渗土工膜。在本发明实施例中，采用该分层填筑方法，有结构简单、施工方便、整体稳定性高的优点，能有效减少差异性沉降，具有很好的实用性。
