2 position of trash rack.
It includes service valve that the tunnel, which reversely presses water steel pipe valve 6,.
It further includes maintenance valve that the tunnel, which reversely presses water steel pipe valve 6,.
A kind of cleaning method suitable for small reservoir shaft intake, the method comprises the following steps:
Step1, head-tank 7 is stored to full water, water body volume is water in diversion tunnel 3 before bulkhead gate in head-tank 7
1/2 or more of body total volume；
Lock is closed under Step2, diversion tunnel bulkhead gate, and waits gate upper water bulk wave dynamic stability；
Step3, lower soil-shifting net 8 is spilt to 1 top trash rack of intake vertical shaft, 2 position, guarantee that soil-shifting net 8 can cover completely and block
Dirty grid 2 and grid top dirt；
Step4, the tunnel opened in diversion tunnel bulkhead gate room 5 reversely press water steel pipe service valve, utilize high-order water
The water-head of pond 7 and upper pond rapid water filling into the diversion tunnel 3 before bulkhead gate, guarantees that the flow velocity of water in tunnel exists
1.0m3/ s or more；
The reverse flow that reservoir is flowed in Step5, diversion tunnel 3 can push back dirt in reservoir together with soil-shifting net 8 together,
Soil-shifting net 8 is tightened at this time, is able to achieve and all dirts are salvaged into disembarkation together, and then complete work of removing contamination.
The beneficial effects of the present invention are: the anti-pushing that water body reverse flow generates in tunnel is dexterously utilized in the present invention
Originally the reservoir dirt for being tightly attached to trash rack for water inlet body is pushed back reservoir by power, and fishing net is recycled to salvage disembarkation, perfect to solve
All the time the shaft intake of puzzlement reservoir operation remove contamination working expenditure when, laborious, technology that personnel safety not can guarantee
Problem.

7 connection, 7 mounting height of head-tank are located at reservoir operation scheme or more, and soil-shifting net 8 is arranged in 1 top of intake vertical shaft
2 position of trash rack.
It include service valve (for controlling water flow it is possible to further which the tunnel is arranged reversely to press water steel pipe valve 6
Movement).
It further include that maintenance valve (needs when for overhauling it is possible to further which the tunnel is arranged reversely to press water steel pipe valve 6
It wants).
A kind of cleaning method suitable for small reservoir shaft intake, the method comprises the following steps:
Step1, head-tank 7 is stored to full water, water body volume is water in diversion tunnel 3 before bulkhead gate in head-tank 7
Body total volume 1/2 or more (such as 1/2,2/3,1(1 indicate it is equal))；
