挤压墙施工技术在柏叶口水库的应用

Application the Technique to Construct Extrusion Wall in Baiyekou Reservoir

柏叶口水库大坝为混凝土面板堆石坝。大坝施工中在垫层料的上游混凝土挤压墙施工技术得到了应用,和传统工艺中的垫层料回填、削坡、斜坡碾压、坡面砂浆碾压等工序相比,简化了施工工序,加快施工进度,提高了施工安全和施工质量,具有保证垫层料的压实质量和提高坡面防护能力以及施工简便等特点。

The Baiyekou Reservoir＇s dam is a concrete facing rockfill dam.The technique to construct concrete extrusion wall above the bedding material of upstream dam slope is applied in this dam＇s construction progress.Compared with the traditional construction working procedure such as backfilling bedding material,scaling,side-slope rolling,rolling mortar in slope surface,this technique simplifies construction procedure,quickens project pace,raises construction security and construction quality.It has many features including ensuring quality to compact bedding material,raising capacity to protect dam slope,and making the construction simple and convenient.
