Be positioned at protecting across ditch diversion tunnel of mud-rock flow coombe for Built hydropower station at present and also there is no more effective methods; mainly according to on-the-spot actual landform geological conditions; cancel former in ditch tunnel, rearrange tunnel in position and connect with former tunnel, avoid tunnel to stand the impact of mud-rock flow.This method construction period is long, progress is comparatively slow, comparatively large, less economical unreasonable on the impact of power station generating, is particularly far from suitable for emergency work.
Utility model content
Technical problem to be solved in the utility model is: providing short, work progress of a kind of construction period not affect, power station normally runs is positioned at blocking safeguard structure across ditch diversion tunnel of mud-rock flow coombe.
The technical scheme adopted for solving the problems of the technologies described above the utility model is: be positioned at blocking safeguard structure across ditch diversion tunnel of mud-rock flow coombe, comprise the diversion tunnel arranged along coombe width, coombe is provided with upstream blocking dam, downstream blocking dam along its width, blocking dam top, upstream, blocking dam top, downstream are connected by the drainage groove arranged along coombe length direction, diversion tunnel between upstream blocking dam, downstream blocking dam, and is positioned at below drainage groove simultaneously.
Further: drainage groove end face is ramped shaped along coombe length direction, and lowest part is positioned at blocking dam side, downstream.
Further: drainage groove is V-type groove.
Further: drainage groove is provided with barricade at the two ends of width.
Further: be provided with pipe bridge below diversion tunnel, pipe bridge comprises bridge pier and bridge plate, and bridge plate top has the groove arranged along diversion tunnel length direction, and the base plate of groove is all fixedly connected with diversion tunnel outer wall with two sidewalls.
Further: blocking dam bottom, upstream is provided with first row water pipe, blocking dam bottom, downstream is provided with second row water pipe, and first row water pipe horizontal level is higher than second row water pipe horizontal level.
Further: inside upstream blocking dam 3 and drainage groove 5 connecting portion, inside downstream blocking dam 4 and drainage groove 5 connecting portion, be equipped with aileron 8.
The beneficial effects of the utility model are: by arranging the overall structure of upstream blocking dam, downstream blocking dam, drainage groove composition, diversion tunnel is become underground structure, drainage groove is used for the overcurrent of mud-rock flow, can effectively avoid mud-rock-flow-impact diversion tunnel, there is local distortion in upstream blocking dam, downstream blocking dam, also can not affect the safety and stability of diversion tunnel under the impact force of mud-rock flow.The utility model construction period short, work progress does not affect power station and normally runs.
