1989年起,我市水利配套建筑物中开始应用加筋土挡墙技术。到目前为止,已在如东、启东、南通三县(市)建造了11座加筋土挡墙。其中10座用于桥台翼墙和路堤挡土墙,1座用于小闸的下游翼墙。实践证明:加筋土挡墙结构稳定可靠,预制装配程度高,施工技术易掌握,造价低于重力式挡墙,是一种比较理想的轻型结构。一、塑料拉条设计参数的选用我市已建的11座加筋土挡墙,全部使用塑料拉条。以塑代钢既节约了钢材,又免除了钢拉条的防锈处理,受到建设单位和施工人员的欢迎。但与钢拉条相比,塑料拉条强度
Since 1989, the city’s water conservancy facilities began to apply reinforced earth retaining wall technology. So far, 11 reinforced earth retaining walls have been built in Rudong, Qidong and Nantong counties (cities). Ten of them are used for abutment wing walls and embankment retaining walls, and one is for the lower gate. Practice has proved that the structure of reinforced earth retaining wall is stable and reliable, the degree of prefabrication is high, the construction technology is easy to grasp and the cost is lower than that of gravity retaining wall, which is an ideal lightweight structure. First, the selection of plastic pull design parameters The city has built 11 reinforced earth retaining wall, all using plastic pull. In order to save plastic steel instead of steel, but also eliminates the steel pull of anti-rust treatment, by construction units and construction workers welcome. But compared with the steel pull, plastic pull strength
