一、水泥土护岸试验原由嘉兴地区位于杭嘉湖平原,河道密布,水运交通发达,京杭大运河横穿过境,主航道长达4500公里。由于机船来往频繁,对两岸冲刷十分严重,每年塌损土地近千亩。解放以来已砌筑护岸1300公里,还剩下3200公里急需护岸。以往护岸采用于砌块石勾缝,不仅价格高,速度慢,而且容易损坏,塌损的块石偷窃严重。加上当地缺乏砂、石料,砌筑护岸的砂石料都得从远地运来,价格昂贵,运输费用大,延缓了护岸的砌筑时间。如桐乡县从六四年以
First, the cement soil revetment test reason Jiaxing area is located in Hangzhou-Jiaxing-Huzhou plain, the river is densely covered, water transport developed, Beijing-Hangzhou Grand Canal across the border, the main waterway up to 4500 km. Due to the frequent ship-to-ship exchanges, the erosion on both sides of the Taiwan Strait is very serious and the land collapses nearly a thousand acres each year. Since the liberation has been masonry revetment 1,300 km, 3200 km left in need of revetment. In the past, bank revetments were used in masonry blocks, which not only were expensive and slow but also easily damaged. In addition, the local lack of sand, stone, masonry gravel sand materials have to come from afar, expensive, transportation costs, delaying the revetment of masonry time. Such as Tongxiang from 64 years
