Detailed description of the invention
For ease of understanding and implementing the utility model, select preferred embodiment of the present utility model to combine accompanying drawing and be described further.
As shown in FIG. 1 to 3, the utility model include along river course width arrange checkdam 1, river course bank be additionally provided with into
The mouth water discharge tunnel 2 that end connects with checkdam 1 upper river, the port of export connects with checkdam 1 downstream river course, water discharge tunnel 2
Base plate be provided with partition wall 3 along water discharge tunnel 2 length direction so that water discharge tunnel 2 formed two cross aquaporins, water discharge tunnels 2
Arrival end be provided with lock chamber 4, lock chamber 4 is provided with twice gate 5, gate 5 is the most corresponding with crossing aquaporin, draining tunnel
Hole 2 is provided with draining near side, river course and props up hole 6, and draining props up that the arrival end in hole 6 is communicated in water discharge tunnel 2, the port of export is communicated in river
Road, is provided with detachable temporary plugging body 7 in water discharge tunnel 2, temporary plugging body 7 cooperation is located at draining and is propped up hole 6 arrival end
Downstream.
Preferably, partition wall 3 is vertically installed in the center position of water discharge tunnel 2 base plate so that two flows crossing aquaporin are identical,
More reasonable structure.And partition wall 2 height can determine according to water flow in dry season, should make partition wall 2 side can meet cross dry season stream want
Ask.Temporary plugging body 7 is located at draining and is propped up the downstream of hole 6 arrival end, and hole 6 arrival end is propped up in distance draining a segment distance, to adjust
Whole water discharge tunnel 2 enters draining and props up the fluidised form of hole 6 current.
Draining is propped up hole 6 and is arranged that should meet draining props up channel definition between hole 6 port of export and checkdam 1 and meet early stage slag requirement,
And hole 6 length is propped up in shortening water discharge tunnel 2 top half length and draining as far as possible.Draining is propped up hole 6 and is arranged at water discharge tunnel 2 temporarily
When the upstream portion of occluding body 7 is constructed, water discharge tunnel construction speed can be accelerated, it is achieved a hole is multiplex as working tunnel
Effect.
