一、概况广东省深圳市东深引水工程,是开发经济特区的一项重要涉外项目。工程规模较大,首先将东江水通过八级抽水站把水位抬高46米,引流至深圳水库,再经过库区内的进水渠道、闸门井、输水管、顶管后座井、电站,最后经过3公里长的方形函渠输往香港,港方要求供水量由目前的9立方/秒增加到25立方/秒,由于存在工程情况特殊,施工技术难度大,工期紧迫,质量要求高等特点,故作为重点攻关施工项目。穿坝输水工程(见图一)由三部分组成: (1) 后座井: 单位体积:1484×984×1000,(高)
I. Overview Shenzhen Dongshen Water Diversion Project in Guangdong Province is an important foreign-related project for the development of special economic zones. The scale of the project is relatively large. First, the Dongjiang River will raise the water level by 46 meters through a pumping station at the 8th level, and it will be diverted to the Shenzhen Reservoir. Afterwards, it will pass through the influent water channel, gate well, water transmission pipe, pipe jacking block, and power station in the reservoir area. After a 3 km long square channel canal was sent to Hong Kong, the Hong Kong side requested that the water supply volume be increased from the current 9 cubic meters/second to 25 cubic meters/second. Due to the existence of special projects, the construction technology is difficult, the duration is tight, and the quality requirements are high. , so as a key research project. The dam transmission project (see Figure 1) consists of three parts: (1) Backseat: Unit volume: 1484×984×1000, (H)
