Abstract
The utility model discloses a double-gate structure for releasing large-traffic tunnel of high water head, a plurality of work gate and maintenance gate that arrange side by side along perpendicular tunnel axis direction are reached including the tunnel, the work gate sets up in maintenance gate below, and work gate and maintenance gate all are located water inlet low reaches, work gate below still is provided with air vent maintenance stair, the quantity of air vent maintenance stair, work gate and maintenance gate is two to cut off through the gate pier, work gate low reaches link up with the tunnel through the gradual change section. The utility model discloses a set up two or more gates side by side along perpendicular hole axis direction, not only effectively shared the size of single-leaf gate, reduced the gate size, reduced the metallic structure preparation, installation, the operation degree of difficulty, increased the area of intaking simultaneously, the manger plate ability of entire structure has also obtained the improvement, need not follow this problem of solving with traditional increase tunnel number again.
Description
Technical field
The utility model belongs to civil works technical field of structures, specifically relates to a kind of double-gate structure for high head and large flow tunnel of releasing.
Background technology
Along with the development of dam construction technique, China has higher requirement to the large storehouse emptying scale of the high dam in Hydraulic and Hydro-Power Engineering and the emptying degree of depth.But, according to the existing gate of China and opening/closing system manufacturing technology level, gate dash head is subject to the two ore control of hydraulic pressure and gate area, namely gate is less, can keep off more head, but gate is less, drawoff discharge is also less, and then reduction project benefit, increase engineering cost, do not reach the design and operation needs of engineering safety economical rationality.Therefore, traditional gate design mode cannot meet the needs of the large discharge engineering of high dam.
Utility model content
For solving the problems of the technologies described above, the utility model provides a kind of double-gate structure for high head and large flow tunnel of releasing.Thus realize, under equal single gate makes requirement, making bleeder quantity and dash head rise to original twice, not only meet the requirement that engineering safety runs, reduce project playout build simultaneously, improve the globality of main structures, add project benefit, reduce engineering cost.
The utility model is achieved by following technical solution.
A kind of double-gate structure for high head and large flow tunnel of releasing, several Service gates comprising tunnel and be arranged side by side along vertical canal axes direction and Emergency Gate, described Service gate is arranged on below Emergency Gate, and Service gate and Emergency Gate are all positioned at water inlet downstream, below described Service gate, be also provided with air vent maintenance stair.
The quantity of described air vent maintenance stair, Service gate and Emergency Gate is two, and is cut off by gate pier.
Described Service gate downstream is connected with tunnel by transition section.
The beneficial effects of the utility model are:
Compared with prior art, the utility model efficiently solves and increases the contradiction that gate discharge can only reduce its dash head, by being arranged side by side two or more gates along vertical hole axis direction, not only the size of single gate is carried out effectively sharing, decrease igfet gate, reduce metal construction and make, install, run difficulty, increase into water area simultaneously, the water-retaining capacity of total have also been obtained raising, need not continue to use traditional increase tunnel number again and solve this problem.Reduce project playout build, improve the globality of main structures, improve hinge operational efficiency; Decrease the restrictive condition of project playout to comparison and choice, slope excavation, building foundation, improve structure construction, run its safety in production coefficient; Decrease construction investment and duration, be conducive to engineering structures secure persistent and run, add project benefit.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-tunnel, 2-air vent maintenance stair, 3-Service gate, 4-Emergency Gate, 5-gate pier, 6-transition section, 7-water inlet.
Detailed description of the invention
The technical solution of the utility model is further described below in conjunction with accompanying drawing, but described in claimed scope is not limited to.
As shown in Figure 1, a kind of double-gate structure for high head and large flow tunnel of releasing described in the utility model, several Service gates 3 comprising tunnel 1 and be arranged side by side along vertical tunnel 1 axis direction and Emergency Gate 4, described Service gate 3 is arranged on below Emergency Gate 4, and Service gate 3 and Emergency Gate 4 are all positioned at water inlet 7 downstream, below described Service gate 3, be also provided with air vent maintenance stair 2.The technical program is by being arranged side by side multiple gate along vertical hole axis direction, not only the size of single gate is carried out effectively sharing, decrease igfet gate, reduce metal construction to make, install, run difficulty, increase into water area simultaneously, the water-retaining capacity of total have also been obtained raising, need not continue to use traditional increase tunnel number again and solve this problem.Reduce project playout build, improve the globality of main structures, improve hinge operational efficiency.
The quantity of described air vent maintenance stair 2, Service gate 3 and Emergency Gate 4 is two, and is cut off by gate pier 5.Air vent maintenance stair 2, Service gate 3 and Emergency Gate 4 are symmetrical about gate pier 5 respectively.
Described Service gate 3 downstream is connected with tunnel 1 by transition section 6.
Adopt technique scheme, achieve under equal single gate makes requirement, bleeder quantity and dash head is made to rise to original twice, not only meet the requirement that engineering safety runs, reduce project playout build simultaneously, improve the globality of main structures, add project benefit, reduce engineering cost.
