挤压混凝土边墙在三岔河水电站混凝土面板堆石坝工程中的应用

Application of Extruded Concrete Side Wall in Sanchahe Power Station CFRD Project

云南保山腾冲猴桥三岔河水电站面板堆石坝迎水坡面采用挤压混凝土边墙施工方法,完全取代了传统的坝体超填、垂直碾压、削去虚土、坡面平整和斜坡碾压工艺,简化了施工程序,加快了施工进度,提高了填筑质量,降低了施工成本,成型断面规矩,维护简单。本文对此加以介绍。

Extruding concrete side wall construction method is adopted for upstream slope surface of Yunnan Baoshan Tengchong Houqiao Sanchahe hydropower station panel rock-fill dam,which completely replaces traditional dam ultrafilling,vertical rolling,surface soil slashing,slope surface flatting and slope rolling process. Therefore,construction procedures are simplified,construction progress is accelerated,filling quality is improved,construction costs are reduced,and the formed cross section is regular,which can be maintained simply. The condition is introduced in the paper.
