在农田基本建设施工中,开凿涵洞、整修梯田、兴修水利、围海造田等,石方作业量都很大。如围海造田,修一米长的堤需要石块约20～40立方米。目前,我国石方的凿岩、装运、整形等基本上是靠手工劳动,工效低,劳动强度大,进度慢。如人工打眼,平均一个人一天只能打一米左右。这就很不适应大搞农田基本建设的要求,迫切要求实现机械化。根据目前各地施工情况,石方作业一般包括采石
In the farmland capital construction, dredging culverts, renovating terraces, water conservancy construction, land reclamation and so on, the stonework operations are large. Such as reclamation of the sea, repair a meter long embankment requires about 20 to 40 cubic meters of stone. At present, China’s rock side of the rock drilling, shipping, plastic and so basically rely on manual labor, low efficiency, labor-intensive, slow progress. Such as artificial drilling, the average person a day can only play about one meter. This is not suited to the requirements of popularizing farmland infrastructures, and urgently requires mechanization. According to the current construction situation around the stonework operations generally include quarrying
