水准点复测情况

1、复测情况 我标段测量组于2010年4月5日开始对K834+000-K844+000段进行复测，于 2010 年 4 月 15 日复测完毕，具体情况如下： 一、概述复测工作共分为三组：基平组、中平组、横段组。对我标段沿线水准点，导线点进行了详细的复测和加密。本标段依据设计院提供的水准点K841+510与K835+320共2个点，闭合实测，共分为两个组每组两个人，两台水准仪平行进行。二、水准基点我标段共有设计院提供的水准点2个(K835+320-K841+510),情况如下。水准点编号高程路线中心桩号位置说明BM1161.490K835+320右侧沙地里水泥桩钢筋BM2163.847K841+51
