对亚行贷款项目老宅庄控导改建工程的设计方案、工程施工及变更情况进行分析。同样施工水位经调水调沙几年后,施工水位降低了1.51m,需相应降低粘土坝胎、坦石护坡底高程,应尽量缩短设计与施工时间间隔,新建坝的坦石粗排,经过一年的沉降稳定后再进行施工,水中进占施工时序性、紧凑型、连贯性特别强,一环扣一环。
Analyze the design plan, construction and alteration of the old house zoned rebuilding project of ADB loan project. After several years of water and sediment regulation, the construction water level will be reduced by 1.51m. Therefore, it is necessary to reduce the elevation of clay dam and tannery revetment accordingly. The design and construction intervals should be shortened as much as possible. After one year of settling and stabilization, the construction will be carried out again. The water occupying and occupying the construction will be of the orderliness, compactness and strong continuity, and the ring will be fastened together.
