Underground excavation type multifunctional ecological fishway construction method
The invention relates to the technical field of water conservancy and hydropower engineering fishway construction, and discloses an underground excavation type multifunctional ecological fishway construction method which comprises the following steps that S1, a cavern type fishway is excavated; s2, cavern type fishway lining is conducted, specifically, segmented construction is conducted, and concrete pouring is conducted in the lining construction sequence that a bottom plate is firstly arranged and then a side top arch is arranged; s3, backfilling and consolidation grouting of the cavern type fishway; s4, partition wall and bracket construction, wherein partition wall construction is conducted from the middle to the holes in the two ends; s5, partition plate and guide plate prefabrication and installation, wherein the partition plate and the guide plate are prefabricated in the hole after construction of the partition wall of the corresponding section is completed; the partition plate and the guide plate are fixed to the side wall of the fishway groove in the mode of expansion bolts and angle steel for installation; s6, mounting a steel grating cover plate; the method has the advantages of small damage to natural vegetation on the shoreside, full utilization of underground resources, extremely small construction occupied area, facilitation of water and soil conservation, small interference to other construction buildings during construction, low overall investment and construction cost, and is worthy of being popularized in subsequent river blocking building planning and design.
本发明涉及水利水电工程鱼道施工技术领域，公开了一种暗挖式多功能生态鱼道施工方法，包括以下步骤：S1、洞室式鱼道开挖；S2、洞室式鱼道衬砌：分段施工，混凝土浇筑采用先底板、后边顶拱的衬砌施工顺序；S3、洞室式鱼道回填及固结灌浆；S4、隔墙及牛腿施工：隔墙施工自中间向两端洞口进行；S5、隔板及导板预制安装：隔板及导板待相应段隔墙施工完成后在洞内进行预制；安装用膨胀螺栓+角钢的方式把隔板、导板固定到鱼道槽的侧墙上；S6、钢格栅盖板安装；本发明对岸边自然植被破坏性较小、充分利用地下资源，施工占地面积极少，有利于水土保持，施工时对其它施工建筑物干扰小，总体投资造价低，值得在后续拦河建筑物规划设计中推广。
