山西省汾南灌区橡胶坝采用螺栓压板锚固,没有浇筑锚固槽之间的混凝土底板和安装橡胶坝底垫片。仅在下压板之间焊接了3mm厚的钢板,下垫50cm的黏土,代替了部分混凝土底板及橡胶坝底垫片。因此节约了工程量,缩短了工期,节省了资金。从1998年挡水运行至今没有出现问题,实践证明,铁底板橡胶坝是一种投资少、止水效果好的橡胶坝新品种,特别适用于在工期要求紧迫的行洪河道上施工,具有推广使用的价值。
Fennan Irrigation District in Shanxi Province rubber bolting anchor plate, there is no pouring concrete floor between the anchor groove and installation of rubber dam bottom gasket. Only 3mm thick steel plates were welded between the lower plates and 50cm of the lower plates were used to replace part of the concrete floor and rubber dam bottom gasket. As a result, the project volume is saved, the construction period is shortened and the capital is saved. Since 1998, there are no problems with the water retaining operation. Practice has proved that the iron floor rubber dam is a new type of rubber dam with low investment and good water stopping effect. It is especially suitable for construction of flood control flood dam with urgent construction period, Use value.
