Detailed Description
The technical solutions of the present invention will be described clearly and completely with reference to the accompanying drawings and detailed description, and it is to be understood that the described embodiments are only some embodiments, not all embodiments, of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.
In the description of the present invention, it is to be understood that the terms "central, lateral, longitudinal, up, down, front, back, left, right, vertical, horizontal, top, bottom, inner, outer" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in fig. 1 only for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.
The utility model discloses technical scheme is a structure of making an uproar falls in reposition of redundant personnel of gas shield dam culvert, and its structural schematic is as shown in figure 1, and it includes multiunit shield board 1, 1 one end of shield board is connected with gas shield dam foundation slab 2, be equipped with gasbag 3 between shield board 1 and foundation slab 2's the contained angle, be equipped with waist wall 4 between adjacent two sets of shield boards 1, its characterized in that, the inside wall culvert pipe 5 that is equipped with of waist wall 4, wall culvert pipe 5 makes the upper reaches and the low reaches of waist wall 4 link up mutually, and by the upper reaches slope downstream.
Through set up wall culvert pipe 5 in waist wall 4 inside, and by the upstream control to wall culvert pipe 5 water yield to reach the purpose of control shield 1 water yield, fine maintenance waterfall view effect, when not needing the view, make wall culvert pipe 5 water yield increase, reduce shield 1 water yield, thereby reduce the water noise of crossing.
In order to control the water passing amount of the wall culvert 5 more flexibly and more conveniently, a wall culvert pneumatic switch 6 is arranged at the port of the wall culvert 5 at the upstream of the waist wall 4.
And a stilling pool 7 is arranged at the downstream of the air shield dam. The stilling basin 7 can quickly change the downward flow into the slow flow, generally can eliminate the kinetic energy of the downward flow by 40-70 percent, and is an effective and economic energy dissipation facility. Through setting up stilling pond 7 in gas shield dam low reaches, run through wall culvert pipe 7 at stilling pond 7 and waist wall 4 upper reaches, through controlling the volume of crossing water of wall culvert pipe 7 to reach the purpose of control shield board 1 water yield, fine maintenance waterfall view effect, when not needing the view, wall culvert pipe 5 water yield increase reduces shield board 1 water yield, thereby reduces the noise of crossing water.
Because the upstream and downstream of the air shield dam have water pressure difference, water flows from the upstream of the air shield dam to the stilling pool 7 through the wall culvert pipe 5, and in order to enable the water passing through the wall culvert pipe 5 to smoothly flow from the upstream of the air shield dam to the stilling pool 7, the wall culvert pipe 5 is set to be in an inclined state from the upstream of the waist wall 4 to the stilling pool 7 from high to low.
When the water passing amount of the shield plate 1 is too large and the waterfall landscape effect is not good, the wall culvert pipe pneumatic switch 6 is opened to maintain the water passing amount of the shield plate 1 within a certain range; when the water flow of the shield plate 1 is too small and the waterfall landscape effect is not good, the pneumatic switch 6 of the wall culvert pipe is reduced, and the water flow of the wall culvert pipe 5 is reduced, so that the water flow of the shield plate 1 is maintained within a certain range, and the waterfall landscape effect is kept.
The water passing amount of the wall culvert pipe 5 is adjusted by adjusting the on-off of the wall culvert pipe pneumatic switch 6, so that the water passing amount of the shield plate 1 is in a certain range, and a good waterfall landscape effect is kept.
In order to increase the control on the water quantity, a plurality of underground culvert pipes 8 are arranged in the foundation slab 2, the structure schematic diagram of the underground culvert pipes is shown in figure 2, and the underground culvert pipes 8 are communicated with the absorption basin 7 and the upstream of the air shield dam. The wall culvert pipe 5 and the ground culvert pipe 8 are matched for use, so that the control on the water quantity is increased, and the water passing quantity of the shield plate 1 is more effectively controlled to be within the water passing quantity range suitable for the waterfall landscape.
Similarly, the culvert 8 performs water flow by the pressure difference between the upstream and the downstream, and the culvert 8 is inclined from the upstream of the air shield dam to the stilling pool 7 from high to low in order to enable the water passing through the culvert 8 to smoothly flow from the upstream of the air shield dam to the stilling pool 7.
The upper end of the underground culvert pipe 8 is provided with an underground culvert pipe pneumatic switch 9, the underground culvert pipe pneumatic switch 9 and the wall culvert pipe pneumatic switch 6 are matched for use, the water passing amount of the underground culvert pipe 8 and the wall culvert pipe 5 is controlled, the water passing amount of the shield plate 1 is effectively controlled, and the good landscape effect is maintained within the water passing amount range suitable for the waterfall landscape.
Meanwhile, when no landscape is needed, the effective noise reduction value reaches 50-60%.
The wall culvert pipe pneumatic switch 6 and the ground culvert pipe pneumatic switch 9 are both of a two-way type, the connection mode of the wall culvert pipe pneumatic switch 6 and the wall culvert pipe 5 and the connection mode of the ground culvert pipe pneumatic switch 9 and the ground culvert pipe 8 are both flange connection, the driving mode is pneumatic, namely a vacuum electromagnetic valve, the wall culvert pipe pneumatic switch 6 is selected according to the diameter of the wall culvert pipe 5 and the water pressure, the ground culvert pipe pneumatic switch 9 is selected according to the required diameter of the ground culvert pipe 8, and the model can be an ancient cooking vessel resistant ZQDF-15F.
The working process is as follows: when the shield plate 1 rises to dam water, when the water quantity is too large and the noise is too large, the wall culvert pipe pneumatic switch 6 and the ground culvert pipe pneumatic switch 9 are adjusted, when the water quantity is too small, the wall culvert pipe pneumatic switch 6 and the ground culvert pipe pneumatic switch 9 are closed, and the adjustment of the size of the two pneumatic switches ensures that the water passing quantity of the shield plate 1 is in a certain range and a certain waterfall landscape effect is kept.
In summary, in order to solve the problems that the existing air shield dam mentioned in the prior art cannot flexibly adjust the water passing amount at the top of the shield plate, cannot well maintain the waterfall landscape effect, and cannot timely make noise when the landscape is not needed, and the normal life and work of the shore residents are affected, the utility model discloses an aspect is to set a wall culvert pipe 5 inside the waist wall 4, and incline from the upstream to the downstream to control the water passing amount of the wall culvert pipe 5, thereby achieving the purpose of controlling the water passing amount of the shield plate 1; on the other hand, the water passing amount of the shield plate 1 is controlled by the cooperation of the wall culvert 5 and the ground culvert 8 after the water passing culvert 8 penetrates between the stilling pool 7 and the upstream of the gas shield dam, so that the aim of controlling the water passing amount of the shield plate 1 is fulfilled, the waterfall landscape effect is well maintained, the water passing amount of the wall culvert 5 and the ground culvert 8 is increased when the landscape is not needed, the water passing amount of the shield plate 1 is reduced, and the water passing noise is reduced.
