Description
Technical field
The utility model relates to a kind of two dam, road structures, especially relates to a kind of two dam, road structures for absorption basin, belongs to Design of The Hydraulic Structure manufacturing technology field.
Background technology
Along with country is to the demand of the clean energy resourcies such as water power, facilitate the construction of Hydraulic and Hydro-Power Engineering, and going deep into further along with water resources and hydropower construction, there is a large amount of dash high dams.In the running of Hydraulic and Hydro-Power Engineering, during in order to reduce dash high dam dam body aperture as table hole, mesopore, deep hole flood discharge, release floodwatering flow, to the scour of dam site and two sides, has built the cushion pool structure for flood-discharge energy-dissipating behind dam accordingly.Two traditional dams, road have been built in a distance, sluicing arch dam downstream lowly choked water dam for being formed water cushion energy dissipating.Described lowly choke water the gravity dam that dam is generally two-way water blocking, be arranged in the end of cushion pool, basic build is upstream vertical surface, and dam crest is flat-top, and downstream face is inclined-plane.Two dams, road of this structure in dam body aperture as table hole, mesopore or deep hole carry out flood discharge time, release floodwatering flow acutely rolls in cushion pool, underwater bed is entered again by two dams, road, dam crest face due to described two dams, road is angular structures with inclined-plane, dam, dam facade with the corner in dam crest face and is connected, thus the effect improving HYDRODYNAMIC CONDITION RELATING TO is not had to the rolling water of the energy that thoroughly do not disappeared entering underwater bed, thus cause earial drainage water the washing away downstream river course climbing over described two dams, road.
Utility model content
Technical problem to be solved in the utility model is: provide a kind of two dam, road structures for absorption basin significantly improving the HYDRODYNAMIC CONDITION RELATING TO of earial drainage water.
For solving the problems of the technologies described above adopted technical scheme be: a kind of two dam, road structures for absorption basin, comprise two dam, the road bodies being arranged on described absorption basin end along water (flow) direction, two described dam, road bodies at least have a dam crest face and inclined-plane, a dam, described inclined-plane, dam is positioned at the downstream of described two dam, road bodies, and described dam crest face and the connection on the corner of described inclined-plane, dam are that curve smoothing transition connects.
The beneficial effects of the utility model are: be connected by the dam crest face forming described two dam, road bodies is set to curve smoothing transition with the connection on the corner of inclined-plane, dam.Thus make the described curve syndeton of described two dam, road bodies, HYDRODYNAMIC CONDITION RELATING TO and the fluidised form of the water of earial drainage rapidly after climbing over described two dam, road bodies has been met in the projection of its cross section, and then reach the object of HYDRODYNAMIC CONDITION RELATING TO of earial drainage water rapidly described in improvement, make described rolling water after the adjustment of two dam, road bodies, fluidised form is more steady, alleviates it and enters washing away underwater bed behind downstream.
Further, described curve smoothing transition connect for circular curve be connected smoothly, elliptic curve is connected smoothly or wet strange curve smoothing transition connection.
The preferred embodiment of such scheme is, the bottom on inclined-plane, described dam and the riverbed in downstream are on the corner connected for anti-cambered surface transition connects.
Further, two described dam, road bodies also comprise the dam facade that is positioned at this dam, two roads body upstream side, and described dam facade and the connection on the corner of described dam crest face are also for curve smoothing transition connects.
Further, the top of described dam facade is the vertical surface perpendicular to water (flow) direction, and bottom is perpendicular to water (flow) direction and the inclined-plane of upstream side extension.

Fig. 2 is the A-A sectional view of Fig. 1;
Fig. 3 is the A detail drawing of Fig. 1;
Fig. 4 is the transverse sectional view that the utility model improves dam, Qian bis-road.
Be labeled as in figure: absorption basin 1, two dam, road body 2, dam crest face 3, inclined-plane, dam 4, curve smoothing transition connection 5, riverbed 6, dam facade 7.
Detailed description of the invention
As described in Figure 4, two dams, road of the prior art effectively can not improve the HYDRODYNAMIC CONDITION RELATING TO of the earial drainage water climbing over described two dam, road bodies, thus cannot alleviate described earial drainage water washing away lower river course.Ask convex for solving above-mentioned technology, as shown in Figure 1, Figure 2 and be a kind of two dam, road structures for absorption basin significantly improving the HYDRODYNAMIC CONDITION RELATING TO of earial drainage water that the utility model provides shown in Fig. 3.Two described dam, road structures comprise two dam, the road bodies 2 being arranged on described absorption basin 1 end along water (flow) direction, two described dam, road bodies 2 at least have a dam crest face 3 and inclined-plane, a dam 4, described inclined-plane, dam 4 is positioned at the downstream of described two dam, road bodies 2, and described dam crest face 3 is that curve smoothing transition connects 5 with the connection on the corner of described inclined-plane, dam 4.5 are connected by the dam crest face 3 forming described two dam, road bodies 2 is set to curve smoothing transition with inclined-plane, dam 4 connection on the corner.Thus make the described curve syndeton of described two dam, road bodies 2, HYDRODYNAMIC CONDITION RELATING TO and the fluidised form of the water of earial drainage rapidly after climbing over described two dam, road bodies 2 has been met in the projection of its cross section, and then reach the object of HYDRODYNAMIC CONDITION RELATING TO of earial drainage water rapidly described in improvement, make described rolling water after the adjustment of two dam, road bodies 2, fluidised form is more steady, alleviates it and enters washing away underwater bed behind downstream.Curve smoothing transition in above-mentioned embodiment connects 5 and is preferably that circular curve is connected smoothly, elliptic curve is connected smoothly or wet strange curve smoothing transition connects.Meanwhile, the bottom on inclined-plane, described dam 4 and the riverbed 6 in downstream are on the corner connected also are set to anti-cambered surface transition and connect.
For further improving HYDRODYNAMIC CONDITION RELATING TO and the fluidised form of described earial drainage water, in conjunction with described in two dam, road bodies 2 also comprise the dam facade 7 that is positioned at this dam, two roads body 2 upstream side, the top of described dam facade 7 is the vertical surface perpendicular to water (flow) direction, bottom is perpendicular to water (flow) direction and the design feature on the inclined-plane of upstream side extension, described dam facade 7 is also arranged described curve smoothing transition with the connection on the corner of described dam crest face 3 and connects 5.Like this, described earial drainage water through the dam facade 7 of described two dam, road bodies and dam crest face 3 on the corner time, 5 can be connected by described curve smoothing transition and carry out a first draft adjustment in advance, and then be that curve smoothing transition connects 5 and adjusts further with inclined-plane, dam 4 connection on the corner through dam crest face 3, eventually pass the adjustment on this inclined-plane, dam 4, just can reach and adjust the described HYDRODYNAMIC CONDITION RELATING TO of earial drainage water and the object of fluidised form to greatest extent.
