史渒杭综合利用工程位于江淮之间丘陵地区,各级渠道总长16,320公里,有80%的渠道需要穿过丘陵起伏地区。其中分干渠比上渠道底宽最大达60米,挖深一般5米左右,挖深10米以上的切岭工程有43处,最深达23米。开工初用锹挖,镐鎯的老方法挖土,工效很低,严重的影响了工程的进展。因此改进挖土方法,已成为提高工效的关键问题。在党的总路线光辉照耀下,六安樊通桥切岭工程
Shi Yong comprehensive utilization of the project is located in the hilly area between the Jianghuai, all levels of channels total length 16,320 kilometers, 80% of the channels need to cross the hilly region. One of the main channel than the channel at the bottom width of up to 60 meters, digging depth is generally about 5 meters, digging more than 10 meters of the Cutling Project 43, the deepest of 23 meters. The beginning of digging with a spade, pickaxe old way of digging, ergonomics is very low, a serious impact on the progress of the project. Therefore, improving the method of excavation has become a key issue to improve work efficiency. Under the glorious shining of the party’s general line, Lu’an Fan Tong bridge cut the ridge project
