上存碾压混凝土重力坝入仓方式研究
|
摘要
根据现场施工条件,福建长泰枋洋水利枢纽工程上存碾压混凝土重力坝,大部分碾压混凝土使用自卸汽车直接从上游侧入仓。为了保证上游二级配防渗区混凝土的施工质量,采用汽车上游直接入仓,只在老混凝土上行走,每仓浇筑时启用两条入仓道路,交叉分仓的形式,为工程的顺利实施及碾压混凝土施工质量提供了有力的保障。
According to the site construction conditions, in Shangcun RCC gravity dam of Fangyang water conservancy project in Changtai,Fujian,most RCC transported directly from the upstream side by dump trucks,in order to ensure the construction quality of the concrete in the upstream secondary granular composition anti-seepage zone, the car is used to enter the warehouse directly from the upstream and only walk on the old concrete, and the form of 2 warehouse entry roads and cross silo distribution is used for each warehouse pouring, which provides a strong guarantee for the smooth implementation of the project and the quality of RCC construction.
