混凝土倒模法施工技术

Construction technique of the concrete reverse mould method

某水库正常溢洪道重建工程要求汛前完成混凝土堰面施工,由于工期紧迫,必须采取适宜的施工方法才能满足要求。施工时通过对滑模法、人工抹面法、倒模法3种堰面混凝土施工方案进行比选,最后确定采用倒模法。采用倒模法浇筑堰面,能够保证堰面的表面平滑,混凝土内部密实度,同时加快了施工速度,保证了工期。

A reservoir normal spillway reconstruction engineering requirements concerned in complete concrete dam surface construction.Because the time is limited,it must adopt feasible construction method to meet the requirements.Construction based on sliding mode method,artificial precausions method,pour modulus method.Through the construction of three concrete weir program selection,the final molding method used to determine.Using reverse mould casting method can ensure the smooth surface of weir,concrete internal construetion,while quicken the construction speed,guarantee the period.
