水利工程建筑物多数都建造在江、河、湖泊、沼泽地附近，这些地方地下水较丰富且水位较高。水工建筑物率的施工现还分采用以往的大开招商法。这样担合利于机械化涌工。特别是控掘机、推土机、自回式回汽车的【合作业，能充分发挥机械担率、好田工用、田高工投。坏而，在开挖的 Most water conservancy buildings are built on rivers, lakes and swamps, where groundwater is abundant and water level is high. Hydraulic construction rate of construction is also divided into use the previous big open Merchants Law. This is in favor of mechanized surging. In particular, control excavators, bulldozers, self-return cars back to the [co-operation, can give full play to mechanical rates, good field work, Tian high cast. Bad, in the excavation
