Hydropower station runner chamber concrete high-pressure water jet dismantling construction method
According to the concrete high-pressure water jet dismantling construction method for the runner chamber of the hydropower station, high-pressure water pressurized and output by the high-pressure water generation equipment is sprayed to the concrete surface through the high-pressure spray gun with multiple degrees of freedom of motion to complete dismantling of concrete in an area to be dismantled; comprising the following steps that S1, seat ring layer concrete is dismantled through high-pressure water jet, and the seat ring layer concrete comprises seat ring layer window concrete and seat ring layer unconfined concrete; s2, removing foundation ring layer window concrete through high-pressure water jet; s3, removing the middle ring layer concrete, the lower ring layer concrete and the coaming layer concrete through high-pressure water jet; s4, unconfined concrete high-pressure water jet removal of the foundation ring layer; s5, removing the foundation bolt concrete through high-pressure water jet; s6, removing interface measurement; and S7, the demolition interface is trimmed, specifically, concrete in the undercut part area of the demolition interface is demolited again. According to the dismantling construction method, the hydropower station runner chamber concrete is dismantled through the high-pressure water jet technology, the requirement for dismantling the runner chamber concrete is met, and the procedure is short and efficient.
本发明提供的一种水电站转轮室混凝土高压水射流拆除施工方法，经过高压水发生设备加压输出后的高压水通过具有多运动自由度的高压喷枪喷射作用至混凝土面上完成对计划拆除区域的混凝土的拆除，包括如下步骤：S1、座环层混凝土高压水射流拆除，座环层混凝土包括座环层窗口混凝土和座环层无约束混凝土；S2、基础环层窗口混凝土高压水射流拆除；S3、中环层混凝土、下环层混凝土、围板层混凝土高压水射流拆除；S4、基础环层无约束混凝土高压水射流拆除；S5、地脚螺栓混凝土高压水射流拆除；S6、拆除界面测量；S7、拆除界面修整，对拆除界面欠挖部分区域混凝土针对性进行再次拆除。该拆除施工方法，应用高压水射流技术进行的水电站转轮室混凝土拆除，满足转轮室混凝土拆除的需要，工序简短高效。
