Background technique
China's karst features are mainly distributed on southwest, karst area account for the one third of the southwest gross area with
On, Karst funnel is typical karst features.In general, the annual precipitation of southwest is abundant, but in precipitation year at any time
Between be unevenly distributed, have apparent seasonal.Since the conditions of water storage of karst area earth's surface is poor, most of precipitation pass through karst
The karst features such as funnel are centralised or decentralised to have many areas so that surface water resources does not enrich into underground karst water system
Even there are problems that Seasonal Water-Deficit outstanding, seriously affects local economy, social development.
Surface water is stored by building reservoir, is the common approach for solving the problems, such as Seasonal Water-Deficit.The rock of karst area
Molten funnel, although having charge for remittance condition in landform, due to the karst waters such as itself and underground karst pipeline, underground river runoff and row
It lets out system to be connected, does not have conditions of water storage.
Summary of the invention
In view of this, the purpose of the present invention is to provide a kind of Karst funnel reservoir and its methods of construction, using karst
Funnel orographic condition builds reservoir, it is made to have conditions of water storage.

3) it constructs:
A. according to design requirement and on-site actual situations, construction special scheme and construction safety scheme are formulated；
B. the construction of Karst funnel reservoir items building is completed according to design drawing and quality requirement.
The beneficial effects of the present invention are:
Karst funnel reservoir of the invention blocks Karst funnel free drainage channel using building is blocked, and is blocking
It is formed between building and the periphery rock mass of the Karst funnel in portion disposed thereon and is used for water storage and the storage area through antiseepage drain process,
So that Karst funnel has the condition that storage surface water forms reservoir；Emptying building can be vented reservoir, to overhaul library
All kinds of buildings in area；Flood releasing structure can drain extra water in time, to ensure that reservoir safety is run；Intake structure can
It connect, is fetched water for producing, living with aqueduct；In addition, since the pollution sources on Karst funnel periphery are limited, soil erosion is asked
Topic is not serious, and therefore, the sediment siltation problem of Karst funnel reservoir does not protrude, and Reservoir Water Quality is also preferable.
