Description
Technical field
The utility model relates to a kind of water inlet arrangement of Hydraulic and Hydro-Power Engineering, be particularly useful for the independent water inlet of arranging, water inlet is can layout area narrow and small, topographic and geologic complicated condition, influent stream direction and the inconsistent independent water inlet of arranging of diversion tunnel axis direction thereafter.
Background technology
Water inlet is divided into integral arrangement water inlet and the independent water inlet of arranging.Integral arrangement water inlet should adapt with multi-purpose project main building thing pattern, as dam formula, river channel water inlet; Independent layout water inlet should be selected corresponding pattern according to landform geological conditions, as tower (bank tower) formula, bank slope formula, gate shaft shaft intake.
But for some engineerings, the impact that arranged by topographic and geologic condition restriction and pivot building thing, water inlet is can layout area very narrow and small, and influent stream direction and diversion tunnel axis direction inconsistent, this has brought great difficulty with regard to the layout of giving water inlet, adopt above any pattern, all cannot solve, therefore, in view of the condition that current Hydraulic and Hydro-Power Engineering water inlet is arranged, research and inquirement is applicable to topographic and geologic complicated condition, novel water intake pattern that layout area is narrow and small has become the problem that design and scientific research personnel pay special attention to.
Summary of the invention
The independent arrangement of the funneling water inlet of a kind of side direction influent stream of the utility model, with solve because of water inlet can layout area very narrow and small, and influent stream direction and diversion tunnel axis direction inconsistent, brought very big difficult problem to the layout of water inlet.
The technical scheme that the utility model is taked is:
Trashrack section pit shaft is fixedly connected with trashrack pier, trashrack is fixedly connected with trashrack pit shaft, trashrack base plate is fixedly connected with trashrack wellbore bottom, the place suitable for reading of funneling contraction section is connected with trashrack base plate below, end opening place is connected with the place suitable for reading of facade turnaround section, this facade turnaround section end opening is connected with gate shaft hypomere water inlet, diversion tunnel axis after trashrack center line and gate shaft hypomere water inlet is inconsistent, gate shaft hypomere top is gate pit shaft, in gate pit shaft, there is gate, trashrack section pit shaft top is connected with inspection platform, trashrack headstock gear, gate hoist is fixedly connected with inspection platform respectively.
The angle of throat of described funneling contraction section is 6 °～10 °;
The turning radius of described facade turnaround section is wide 3 ~ 5 times in Qi Dong footpath or hole.
The utility model feature is:
(1) influent stream direction and diversion tunnel direction are inconsistent
Utilize influent stream direction with diversion tunnel direction is inconsistent thereafter, trashrack, towards river valley, has been solved to the problem that water inlet front end channel of approach cannot be arranged;
(2) be suitable for water inlet unfavorable geological condition
The funneling water inlet of side direction influent stream, trashrack is towards river valley one side, its excess-three face is reinforced concrete structure, form trashrack pit shaft, effectively reduce the height of opening of side slope, though side slope local instability, the impact that cushions or avoid landslide to impact pit shaft by being located at trashrack pit shaft platform around, avoid again the slag body on landslide to roll into water inlet, cause water inlet to block simultaneously.Therefore, the funneling water inlet of side direction influent stream can effectively reduce its excess-three face slope excavation height of water inlet, and can solve side slope and may shakiness cause water inlet obstructing problem;
(3) the each position of water inlet characteristics of compact layout
Adopt funneling contraction section to be connected the runner between trashrack and gate shaft with facade turnaround section, make water inlet characteristics of compact layout, solved water inlet because of can layout area narrow and small, the problem of difficult arrangement;
(4) solve the unappeasable problem of water inlet minimum inundation depth
Adopt the funneling water inlet of side direction influent stream can reduce gate shaft floor elevation, solved because river course and topographic and geologic condition etc. are former thereby cause water inlet floor elevation can not meet minimum inundation depth requirement, avoided water inlet to produce air-breathing funnel.
(5) be beneficial to and enter as early as possible hole
Adopt the funneling water inlet of side direction influent stream can reduce gate shaft floor elevation, solved tunnel after gate shaft and entered the upper inadequate problem of overlying strata body of hole point, avoid moving after the point of hole, saved engineering quantity.
(6) being beneficial to diversion tunnel arranges
Adopt the funneling water inlet of side direction influent stream can solve the contradictory problems of diversion system and pivot building thing layout, as certain engineering water inlet is arranged in the abutment position of dam, if adopt conventional layout, diversion tunnel will be walked around abutment and pass through in the massif of dam abutment, arrange comparatively difficulty, adopt the funneling water inlet of side direction influent stream, beyond the safe distance that diversion tunnel can allow at basement rock under dam, pass through, solved the problem of the contradiction of diversion system and hinge layout.
Adopt the funneling water inlet of side direction influent stream, by adjusting the base slope of gate shaft floor elevation and adjustment tunnel, can avoid or reduce the impact of bad geological section on diversion system.
Owing to adopting side direction influent stream, influent stream direction can be inconsistent with diversion tunnel axis direction, thereby the layout of diversion tunnel can be more straight smooth and easy, can make hole line shorter, reduces head loss; By adjusting gate shaft floor elevation and tunnel base slope, can shorten or cancel tunnel inclined shaft or vertical shaft and arrange, reduce difficulty of construction.
The utility model is simple in structure, stable, safe and reliable to operation, easy construction, is applicable to the independent water inlet of arranging, the water inlet of especially narrow and small for layout area, topographic and geologic complicated condition, head loss is little, diversion system arrange straight smooth and easy, there is good application prospect.The utility model is a kind of water inlet layout pattern of very economical practicality.
