Debris flow three-dimensional grating dam and construction method thereof
The invention discloses a debris flow three-dimensional grating dam and a construction method thereof. The three-dimensional grating dam comprises a foundation part, a rod piece system, a dam top part, a monitoring and early warning system and a power supply system. In the assembly integral type design, the foundation part is arranged and poured according to the terrain, the rod piece system is in an assembly integral type, and assembly adjustment of a frame main body structure and the grating and system internal force transmission are achieved by means of symmetrically inserting the two ends of a beam into axial grooves of frame columns, inserting supporting columns into connecting openings, filling and adjusting independent cushion blocks, additionally arranging shock insulation elements and the like. The invention discloses a dam crest assembly type tensioning rod piece system. And the monitoring and early warning system monitors dam body and environment dynamic states. The invention further provides a cushion block assembly design rule. The vertical and horizontal multi-span frame characteristics are utilized, and the three-dimensional blocking function of multi-layer penetration and graded blocking is achieved. Through prefabricated assembly type optimization, the overall structure and the permeability performance of the grille can be adjusted in design construction service. The technology balances the flexibility and stability of the grating dam, and provides a new conception of a blocking and discharging project for adjusting the overall and local structures of the dam according to a prevention target.
本发明公开泥石流立体格栅坝及其施工方法。立体格栅坝包括基础部、杆件体系、坝顶部、监测预警系统、供电系统。装配整体式设计中，基础部依地形地势布局浇筑，杆件体系是装配整体式，通过梁两端对称插入框架柱轴向槽内，支柱插入连接口，独立垫块填充调节，增设隔震元件等手段，实现框架主体结构与格栅装配调节，及体系内力传递。坝顶部装配式拉紧杆件体系。监测预警系统监测坝体及环境动态。还提供垫块装配设计规则。发明利用纵横多跨框架特征，实现多层透过与分级拦截的立体拦防功能。经预制装配式优化，整体结构与格栅透过性能在设计施工服役中均能调整。技术平衡格栅坝灵活与稳固性，提供根据防治目标调整坝整体与局部结构的挡排工程新构思。
