一、计算规则1.凡槽底宽度在3m以内,且槽的长度大于槽宽3倍的,按挖地槽计算。其工程量:外墙按图示尺寸的中心线长度,内墙按基槽槽底净长线计算,凸出部分的体积应并入地槽工程量内计算。各种检查井和排水管道接口等处,因加宽而增加的工程量均不计算,但铺设铸铁给水管道时接口处
First, the calculation rules 1. Where the bottom width of the groove within 3m, and the length of the groove is greater than 3 times the width of the groove, according to the calculation of the digging groove. The amount of work: the length of the centerline of the external wall according to the size of the figure, the internal wall is calculated by the net long line at the bottom of the groove, and the volume of the protruding part should be integrated into the quantity of the earthwork. For various inspection wells and drainage pipelines, etc., the increase in the amount of work due to widening is not calculated, but the interface of the laying of cast iron water supply pipes
