Construction method of bridge and culvert cone slope geotextile
The invention provides a construction method of bridge and culvert cone slope geotechnical cloth. The construction method comprises the following steps that 1, soft foundation treatment and structure construction of a bridge abutment, a culvert or a channel are completed; 2, the cone slope foundation is treated; 3, a cone slope soil body and a bridge and culvert abutment back soil body are filled at the same time, a layer of geotechnical cloth is filled and laid, and the geotechnical cloth is laid in the longitudinal and transverse directions in a crossed mode; and 4, reverse folding is conducted when the geotechnical cloth is laid to the slope toe. According to the construction method of the bridge and culvert cone slope geotextile, the geotextile is laid in the bridge and culvert cone slope soil body in the longitudinal direction and the transverse direction, the position, close to the cone slope toe, of the geotextile is reversely folded back, and the reversely folded geotextile and the geotextile laid on the lower layer need to be filled with a layer of soil, so that the stability of the cone slope soil body can be enhanced, and the overall stability of a roadbed is further enhanced; and the construction quality of bridge and culvert abutment back backfilling and cone slope soil backfilling is improved.
本发明提供了一种桥涵锥坡土工布的施工方法,包括以下步骤：步骤1，完成桥梁桥台、涵洞或通道软基处理及结构物施工；步骤2，对锥坡基础进行处理；步骤3，同时填筑锥坡土体和桥涵台背土体，填筑一层，铺设一层土工布，且沿纵横向交叉铺设土工布；步骤4，铺设土工布到坡脚时应进行反折叠。本发明提供的桥涵锥坡土工布的施工方法,通过在桥涵锥坡土体内沿纵横向铺设土工布，并将土工布在靠近锥坡坡脚处反折回来，在反折的土工布与下层铺设土工布要填筑一层土，可增强锥坡土体的稳定性，进一步增强路基整体的稳定性，提高了桥涵台背回填及锥坡土体回填的施工质量。
