Inverted-arch plunge pool structure adapting to valley width deformation
The invention provides an inverted-arch plunge pool structure adapting to valley width deformation. The structure comprises an inverted-arch bottom plate, arch supports and two bank side walls, the arch supports are anchored on mountain bodies, and the inverted-arch bottom plate is formed by tightly connecting a plurality of plates; the inverted-arch bottom plate plunge pool structure is providedwith elastic structural joints capable of eliminating valley width shrinkage deformation of the mountains on the two banks without influencing load transfer, the elastic structural joints are arrangedat the joints between the arch supports and the side walls and at the riding track structural joints of the two bank side walls, the elastic structural joints are filled with compressible and recoverable elastic materials, and the elastic structural joints can meet the requirement for elastic compressive deformation performance and bear water flow scouring and pulsating water pressure. Accordingto the inverted-arch plunge pool structure adapting to valley width deformation, the stability of the plunge pool bottom plate can be effectively enhanced, and the safety requirement for flood discharge and energy dissipation of a high dam is met; and the plunge pool is enabled to adapt to the valley width shrinkage deformation of the mountains on two banks after water storage, the anchoring workamount of the plunge pool can be remarkably reduced, investment is saved, and the inverted-arch plunge pool structure can be popularized and applied to alpine and gorge region large-flow high-water-head flood discharge and energy dissipation building engineering.
本发明提供了一种适应谷幅变形的反拱水垫塘结构，包括反拱底板、拱座、两岸边墙，拱座锚固于山体，反拱底板由多块板块紧密连接而成；所述反拱底板水垫塘结构设置能消除两岸山体的谷幅收缩变形而不影响所述荷载传递的弹性结构缝，所述弹性结构缝设置在拱座与边墙之间的接缝、两岸边墙马道结构缝处，弹性结构缝内充填可压缩可恢复的弹性材料，此弹性结构缝能够满足弹性受压变形性能并承受水流冲刷和脉动水压力作用。本发明能有效增强水垫塘底板的稳定性，满足高坝泄洪消能安全要求；又能使水垫塘适应蓄水后两岸山体的谷幅收缩变形，可显著减少水垫塘的锚固工程量、节约投资，可推广应用于高山峡谷大流量高水头泄洪消能建筑物工程中。
