Construction method for building water intake in built reservoir by adopting island building method
The invention discloses a construction method for building a water intake in a built reservoir by adopting an island building method, and belongs to the technical field of water conservancy and hydropower engineering.The method comprises the following steps that S1, surveying and lofting are conducted, the position of a construction platform is determined according to geometric dimensions and plane positions of a water intake lock chamber to be built and a water delivery tunnel, and the construction platform is filled at the construction position; s2, a building envelope is constructed on the construction platform; s3, foundation pit excavation is conducted downwards from the top face of the construction platform, a lining wall and a support are constructed at the same time, and excavation is conducted to the bottom of the water intake through a reverse method; s4, constructing a cushion layer and a bottom plate at the bottom of the foundation pit, and sealing the bottom of the foundation S5, a gate is installed; and S6, an open channel in front of the water intake is excavated underwater, and the diversion tunnel communicates with the reservoir. The construction method is simple and convenient, the water intake structure is safe and reliable, the temporary engineering underwater dismantling amount of the construction platform is small, investment is saved, the influence on the surrounding environment of a reservoir and a lake is small, and the construction period is short.
本发明公开了一种在已建水库采用筑岛法修建取水口的施工方法，属于水利水电工程技术领域，该方法包括以下步骤：S1：测量放样，根据拟建取水口闸室和输水隧洞几何尺寸和平面位置确定施工平台位置，在施工位置填筑施工平台；S2：在施工平台上施工围护结构；S3：从施工平台的顶面往下进行基坑开挖，并同时施工内衬墙和支撑，逆做法开挖至取水口底部；S4：在基坑底部施工垫层和底板，基坑封底；S5：安装闸门；S6：在水下开挖取水口前方的明渠，连通引水隧洞和水库。本发明的施工方法简便，取水口结构安全可靠，施工平台临时工程水下拆除量小，投资省，对水库、湖泊周边环境影响小，施工工期短。
