Reverse osmosis water processing method and reverse osmosis drainage system in construction period of concrete faced rockfill dam

Abstract

The invention discloses a reverse osmosis water processing method and a reverse osmosis drainage system in a construction period of a concrete faced rockfill dam. A drainage blind material is arranged in a horizontal interface between a transition area and an upstream rockfill area, a sleeving is connected with one side, arranged on the upper stream, of the drainage blind material, the other side of the sleeving is connected with a horizontal drain pipe with a one-way water stop valve, connection threads are respectively arranged outside two ends of the horizontal drain pipe, the other side of the horizontal drain pipe is connected with a drainage hose, the other end of the drainage hose is placed in a water-collecting well, and a vertical drain pipe is further arranged. The reverse osmosis water processing method and the reverse osmosis drainage system in the construction period of the concrete faced rockfill dam are particularly applicable for reverse drainage in the construction period of the concrete faced rockfill dam, wherein the concrete faced rockfill dam is deep in foundation excavation of riverbed section toe boards, and long in upstream bedding filling construction period, and a dam body needs flood crossing and water retaining.

Description

technical field [0001] The invention relates to the technical field of face rockfill dams, in particular to a reverse osmosis water treatment method and a reverse osmosis drainage system during the construction period of a face rockfill dam. Background technique [0002] In water conservancy and hydropower projects, due to the needs of irrigation water intake or power generation, it is usually necessary to build a dam to form a reservoir. Many dams under construction and proposed to be constructed choose concrete face rockfill dams. The plinth foundation on the upstream side of the face rockfill dam is generally located on complete and hard bedrock. Due to the deep excavation of the plinth and the inner slope of the plinth, the upstream side of the dam foundation is lower than the downstream side. During the construction period, the construction water and rainwater in the dam area etc. can not be discharged downstream freely, and gather to the upstream side of the dam body t...
