Fig. 1 is slag field structure floor map behind key dam dam of the present invention;
Fig. 2 is slag field structure generalized section behind key dam dam of the present invention.
Detailed description of the invention
As illustrated in fig. 1 and 2, it is after waste region is located at rock, the waste of the main stacking key dam dam foundation, shore protection excavation, building stones field excavation, and the waste of temporary works excavation, top, waste region and side slope establish greening soil erosion management, suitable elevation establishes packway, drainage prism and collector drain is established in slag body behind dam, in order to discharge the infiltration in slag body and the drainage channel as key dam, both produce reverse water pressure power after can preventing construction period panel, drainage in dam body can be kept unobstructed in the runtime again.
Establish drainage prism in slag body behind dam, both sides drainage prism is located at and closes in the slag body of bank slope, main infiltration of discharging in high-order bit dam body and slag body; Establish main drainage prism between bottom slag body, in main drainage prism, establish collector drain, be the arterial drainage passage of key dam and slag body, produce reverse water pressure power after both can preventing construction period panel, drainage in dam body can be kept unobstructed in the runtime again.
3 draining stainless steel tubes established by panel, stretch into collector drain, (comprise slag body periphery) and be provided with system drain dyke behind dam, discharge both sides massif and dam body surface heavy rain charge for remittance.
After waste region is located at rock, the excavation wastes such as the mainly waste of the stacking key dam dam foundation, shore protection excavation, building stones field excavation, and temporary works, top, waste region and side slope establish greening soil erosion management, establish packway respectively at suitable elevation.Establish drainage prism and collector drain in slag body behind dam, in order to discharge the infiltration in slag body and the drainage channel as key dam, after both can preventing construction period panel, produce reverse water pressure power, drainage in dam body can be kept unobstructed in the runtime again.
Within waste region is positioned at scope line of taking over the land for use behind dam beyond rock dam body behind dam, mainly stack the excavation wastes such as the key dam dam foundation and shore protection excavation, the waste of building stones field excavation and temporary works, top, waste region and side slope establish greening soil erosion management.
Drainage prism is established in slag body behind dam.Both sides drainage prism is located at and closes in the slag body of bank slope, main infiltration of arranging in high-order bit dam body and slag body; Establish main draining and rib body between bottom slag body, in main drainage prism, establish collector drain, be the arterial drainage passage of key dam and slag body, produce reverse water pressure power after both can preventing construction period panel, drainage in dam body can be kept unobstructed in the runtime again.3 draining stainless steel tubes established by panel, stretch into collector drain, (comprise slag body periphery) and be provided with system drain dyke behind dam, discharge both sides massif and dam body surface heavy rain charge for remittance.
