在推土机修梯田施工实践中,为了解决人工培埂的劳力不足,我们在1975-1976年机修梯田时,试用了推土机碾压人工切削的筑埂方法进行地埂培修,获得初步效果,现小结如下: 一、施工方法 1、培挡土埂。机修梯田时,自上而下逐台修筑。首先在已定地埂线上用人工培高一尺左右的地埂。此埂除做为推土标记外,主要起挡土作用,以免把土推到埂线外,浪费工时,增加成本。
In the practice of bulldozers to repair terraced fields, in order to solve the labor shortage of manpower training, we trained in 1975-1976 terraced fields, the trial of a bulldozer rolling artificial cutting method of building ground 埂 training, obtain the initial results, are summarized As follows: First, the construction method 1, cultivate soil 埂. Machine repair terraced fields, built from top to bottom by Taiwan. First of all, it has been set to the ground line with artificial training about a foot of ground 埂. In addition to as a bulldozer mark, the main role from the earth, so as not to push the soil outside the line, wasting hours and increase costs.
