Prefabricated drainage cavity top arch structure of drainage gallery
The prefabricated drainage cavity top arch structure of the drainage gallery comprises a plurality of sections of top arch structures arranged at the top of the drainage gallery, and the top arch structures are sequentially arranged in the length direction of the drainage gallery and connected with one another; drainage cavities and reserved drainage holes communicated with the drainage cavities are formed in the top arch structures, the reserved drainage holes are vertically formed above the drainage ditches of the drainage gallery, and the drainage cavities of the adjacent top arch structures are communicated. According to the method, the drainage hole of the dam body of the dam can be rapidly positioned on the drainage gallery, the drainage hole can be communicated with the drainage ditch of the drainage gallery without accurate positioning by complex control means, and smooth drainage of seepage water of the drainage hole of the dam is guaranteed; and the structure can also be used as a permanent structure on the top of the drainage gallery for supporting and protecting.
本发明公开了一种排水廊道预制排水空腔顶拱结构，包括多段设置在排水廊道顶部的顶拱结构，顶拱结构沿排水廊道的长度方向依次排列并相互连接；所述顶拱结构内设有排水空腔以及与排水空腔连通的预留排水孔，预留排水孔竖直设置在排水廊道的排水沟上方，相邻顶拱结构的排水空腔连通。本发明不仅能够快速实现大坝坝体排水孔在排水廊道上的快速定位，不需要复杂的控制手段进行准确定位即可将排水孔与排水廊道的排水沟连通，保证大坝排水孔渗水的顺利排出，还能够作为排水廊道顶部的永久结构起到支撑和保护作用。
