Suspended anchor cable lattice beam expansive soil slope retaining structure and construction method
The invention relates to the technical field of expansive soil side slope supporting and retaining, in particular to a suspended anchor cable lattice beam expansive soil side slope supporting and retaining structure and a construction method.The side slope supporting and retaining structure comprises anchorage piers, suspended lattice cross beams, suspended lattice longitudinal beams, pre-stressed anchor cables, a supporting and retaining structure foundation and a supporting and retaining structure top beam; the anchorage piers, the lattice cross beams and the lattice longitudinal beams are integrally formed on the slope surface of the expansive soil side slope in a cast-in-place mode through reinforced concrete at a time, the anchorage piers are arranged in notch grooves of the slope surface and make direct contact with the expansive soil side slope, and the lattice cross beams and the lattice longitudinal beams are rigidly connected to the side faces of the anchorage piers and are away from the slope surface of the expansive soil side slope by a certain suspension height. The supporting and retaining structure foundation and the supporting and retaining structure top beam are formed at the two ends of the lattice longitudinal beam through cast-in-place reinforced concrete in a later-stage multi-time pouring and tamping mode and arranged at the slope toe and the slope top of the expansive soil slope respectively. The method can be suitable for reinforcement treatment of excavation side slopes or natural side slope projects with different scales and different heights in expansive soil areas.
本发明涉及膨胀土边坡支挡技术领域，具体涉及一种悬空式锚索格构梁膨胀土边坡支挡结构及施工方法，该边坡支挡结构，包括锚墩、悬空式格构横梁、悬空式格构纵梁、预应力锚索、支挡结构基础及支挡结构冠梁，所述锚墩、格构横梁及格构纵梁在膨胀土边坡坡面整体现浇钢筋混凝土一次成型，其中所述锚墩设置于坡面刻槽内与膨胀土边坡直接接触，所述格构横梁和所述格构纵梁刚接于锚墩侧面并距膨胀土边坡坡面一定的悬空高度，所述支挡结构基础及所述支挡结构冠梁分别采用现浇钢筋混凝土后期分次浇捣成型于格构纵梁两端，分别设置在膨胀土边坡的坡脚和坡顶。本发明能够适用于膨胀土地区规模不一、高度各异的挖方边坡或自然边坡工程的加固治理。
