坡改梯工程设计多为石坎坡改梯或土坎坡改梯。结合贵州省思南县坡耕地治理实际情况,针对土层厚、石料来源稀少的地区特点,采用混凝土框格护坡坡改梯模式进行了治理。相比石坎坡改梯,平均节约投资39 889.10元/hm2,节约66.26%。实践证明,混凝土框格护坡坡改梯具有梯坎稳定性好、投资成本低、施工影响度低、耕地破坏小、景观协调度高、生态效益好的优势,为相似地区的坡改梯工程提供了一种新思路。
To change the ladder slope engineering design mostly stone ridge slope or ridge slope to change the ladder. According to the actual situation of sloping farmland management in Sinan County, Guizhou Province, aiming at the regional characteristics of thick soil and scarce source of raw materials, it was treated by the concrete frame slope protection and slope changing mode. Compared with stone slope to change the ladder, the average savings of 39 889.10 yuan / hm2, saving 66.26%. Practice has proved that the concrete sash slope to improve the ladder with ladder stability, low investment costs, low impact of construction, arable land damage is small, landscape coordination is high, the ecological benefits of good advantage for similar areas of slope to ladder project A new idea.
