Sand setting clear water type river channel section structure for mountain torrent region
The invention belongs to the technical field of municipal administration and water environment, and particularly relates to a sand setting clear water type river section structure for a mountain torrent region, which comprises a main river and a revetment, and a gate dam is arranged at the downstream of the river; concrete retaining walls are arranged on two sides of the main river channel, and shallow water areas are formed between the outer sides of the retaining walls and the revetment; a gabion wall with the height of 30-50 cm is arranged at the top of The top elevation of the retaining wall is 60-80 cm lower than the normal water level, and the flood level elevation is lower than the top elevation of the retaining wall. The normal water level of the river channel is higher than the designed and calculated flood level, and the flood level elevation is lower than the concrete retaining wall embankment top elevation. And the flood in the mountain flood period has small impact on both banks. A shallow water area is arranged on the outer side of the main riverway to provide a natural survival space for riverway organisms. By arranging the gabion wall, large impurities brought by upstream mountain torrents can be filtered, water quality exchange of the riverway and the shallow water area is not affected, it is guaranteed that the water ecological environment is not damaged, and the influence on the shallow water area when the water quality and the water level of the main riverway fluctuate greatly is reduced.
本发明属于市政及水环境技术领域，具体涉及一种用于山洪地区的沉砂清水型河道断面结构，包括主河道，以及驳岸，河道下游设置闸坝；主河道两侧采用混凝土挡墙，挡墙外侧与驳岸之间构成浅水区；挡墙顶部设置30‑50cm高石笼墙；所述挡墙顶高程低于常水位60‑80cm,洪水位高程低于挡墙顶高程。本发明河道常水位高于设计核算的洪水位,且洪水位高程低于混凝土挡墙堤岸顶高程。山洪期洪水对两岸冲击较小。在主河道外侧设置浅水区，为河道生物提供生存的自然空间。通过设置石笼墙，可以过滤上游山洪带来的大型杂质，不影响河道及浅水区的水质交换，保证水生态环境不被破坏，减小主河道水质及水位波动较大时对浅水区的影响。
