龙马水电站面板堆石坝坝体填筑施工工艺

为了加快面板堆石坝坝体填筑过程中的沉降量,避免由于坝体填筑速度过快,面板施工没有预留沉降期,坝体施工期沉降对面板造成危害,龙马水电站在施工中采取了通过取消次堆石区、设置低压缩区、主堆石料采用进占法卸料、加大洒水力度及增加设备吨位等措施,加大了坝体在施工过程中的沉降量,大大缩减了后期的二次沉降,从而取得了良好的成效,可供...

Construction Technology of Long Face Rockfill Dam Body Filling

In order to speed up the panel dam body in the process of filling the settlement and avoid the dam filling too fast and panel construction settlement period,no reserve dam to cause harm to the panel during the settlement in the construction of hydropower station,long taken through the cancel time pile of stone area,set low compression area,Lord of rockfill moved the unloading,increase of water intensity and increase equipment tonnage measures,increase the dam in the construction process of the settlement and greatly curtailed the later two times,so the settlement achieved good results,and available for other similar project construction reference.
