过去我们所建的渡槽,都是采用橡皮或沥青麻筋作止水材料,由于前者有造价较高,且经一定时间,橡皮会老化变形,螺拴会锈蚀,止水效果随之降低的弱点;后者则更有在日光曝晒下较易老化变形,止水效果更易于降低的缺点。为解决这一问题,1972年,我们在电白县罗南第一期工程二千多米渡槽上,试用木屑水泥作止水材料,结果获得成功,从1975年起,已在全区全面推广使用。实践证明:木屑水泥具有施工操作技术简
In the past we built the aqueduct, are made of rubber or asphalt hemp tendon for water stop material, due to the former cost is higher, and after a certain period of time, the rubber will be aged, the bolt will rust, water stop the effect of reducing the weakness ; The latter is more prone to weathering in the sun exposure deformation, water-stop effect easier to reduce the shortcomings. In order to solve this problem, in 1972, we experimented with sawdust cement as a stop-water material on the more than 2,000-meter aqueduct of the first phase project of Luonan in Dianbai County. The result was a success. Since 1975, it has been fully promoted in the region use. Practice has proved that: sawdust cement construction technology has a simple operation
