Flat Mining Cost Analysis on the Borrowpit in the South-to-North Water Diversion Middle Route Project
In the process of water conservancy engineering construction,when the excavation quantity cannot meet the filling requirements,it is often necessary to select another borrowpit for mining.If there is a significant difference between the natural moisture content of the soil in the borrowpit and the optimal moisture content for filling,the flat mining method can be chosen for construction to adjust the moisture content of the filling soil.Due to the influence of weather and soil moisture content,the construction process of flat mining soil will also be adjusted accordingly.Moreover,there is no direct corresponding sub item in the current quota of the Ministry of Water Resources,which makes it difficult to determine the cost of this part in various stages of engineering construction.This article takes practical engineering as an example to analyze its resource allocation,production efficiency,and cost calculation,forming a construction quota.Based on the bidding situation of the observed engineering,the direct cost of flat mining in the soil material field is calculated,aiming to provide a basis for investment control in similar engineering projects.
