Description

Technical Field

[0001] The invention relates to the technical field of full reservoir basin surface anti-seepage in reservoir basin engineering, and in particular to a reservoir bottom gallery natural ventilation system for full reservoir basin surface anti-seepage and an implementation method thereof. Background Art

[0002] The reservoir basin with anti-seepage on the entire reservoir basin surface is generally equipped with a reservoir bottom corridor, which is the key drainage and observation channel of the reservoir basin. In the prior art, the anti-seepage reservoir bottom corridor structure on the entire reservoir basin surface disclosed in Chinese Patent Application Nos. 2022115544737 and 2022233193607, although a corridor extension section with priority drainage is set to solve the diversion problem during the construction period. However, during operation, in order to monitor the leakage at the bottom of the reservoir, the operation and inspection personnel need to enter the corridor regularly for inspection. Therefore, it is necessary to ensure that the air in the corridor is fresh to avoid the accumulation of dirty gases and pose a threat to personnel health. Furthermore, due to the large size of the corridor system, if powered ventilation is used, forced ventilation is required before the operation and inspection personnel enter, which is not only time-consuming and energy-consuming, but also requires regular maintenance of the equipment, which greatly reduces the inspection efficiency and increases the operating cost.

[0003] Based on the above situation, the present invention proposes a natural ventilation system for a reservoir bottom gallery with anti-seepage on the entire reservoir basin surface and an implementation method thereof, which can effectively solve the above problems. Summary of the invention

[0023] like Figure 1 As shown in the figure, the natural ventilation system of the gallery at the bottom of the reservoir with anti-seepage on the whole reservoir basin surface includes: A drainage and observation gallery 2 is set up at the bottom of the reservoir; A traffic and ventilation corridor 4 is set up on the slope section of the reservoir basin; A drainage and traffic corridor 3 is arranged at the lowest part of the reservoir bottom and leads to the outside of the reservoir basin 1; The traffic and ventilation corridor 4, the drainage and traffic corridor 3 and the drainage and observation corridor 2 at the bottom of the reservoir are interconnected; A hothouse 5 is provided at the exit of the traffic and ventilation corridor 4, and an air vent 15 is provided on the hothouse 5. The air vent 15 is opened at the highest point of the hothouse 5; The system forms an air circulation channel, and air enters from the drainage and traffic corridor 3, flows through the drainage and observation corridor 2, and finally is discharged from the air outlet 15 of the greenhouse 5 at the exit of the traffic and ventilation corridor 4. Specifically, the entrance of the drainage and traffic corridor 3 serves as the entrance of the gas in the corridor, and the air outlet 15 of the greenhouse 5 serves as the air outlet, so as to realize natural ventilation of the corridor.

[0024] like Figure 5 , Figure 6 , Figure 7 and Fig.10 As shown, the wall of the greenhouse 5 is set as a double-layer composite plate structure, which includes an outer transparent heat-enhancing material plate 11 and an inner metal plate 13. The outer transparent heat-enhancing material plate 11 and the metal plate 13 are connected by a room support frame 12. Specifically, the outer transparent heat-enhancing material plate 11 can be a transparent tempered glass plate, and the metal plate 13 can be a steel plate. The steel plate has a low specific heat and can heat up quickly after absorbing the same amount of heat. The high temperature difference accelerates the transfer of heat from the steel plate to the air, thereby accelerating the temperature rise of the air. The room support frame 12 includes a plurality of steel sections arranged at intervals, which are fixed to the concrete bottom plate 6 of the greenhouse 5 at the bottom.

[0025] The roof 7 of the greenhouse 5 is provided with a single-layer transparent heat-enhancing material plate 16, and the single-layer transparent heat-enhancing material plate 16 is supported by a roof support frame 17. Specifically, the single-layer transparent heat-enhancing material plate 16 can be a transparent tempered glass plate. The roof support frame 17 includes a plurality of steel sections arranged at intervals.

[0026] The metal plate 13 of the inner layer of the wall of the greenhouse 5 has gaps between the upper and lower ends and the bottom plate of the greenhouse 5 and the roof 7 of the greenhouse 5, respectively. Figure 4 As shown, the reserved gap is 20 cm, which is used as a series air vent 14 to accelerate heat exchange. The bottom floor of the greenhouse 5 is cast as a concrete floor 6, and the surface of the concrete floor 6 is painted with floor paint. The floor paint is black, red or other colors with high absorption rate and low reflectivity.

[0027] A notch is provided on the uppermost portion of the transparent heat-enhancing material plate of the greenhouse 5 wall or the transparent heat-enhancing material plate of the greenhouse 5 roof 7, and the notch serves as an air vent 15. Specifically, when the air vent 15 is provided on the roof 7, a rain cover is provided above the air vent 15.

[0028] The arrangement of the walls and roof of the greenhouse 5 should be conducive to the collection of solar energy and the escape of air.

Figure 2 and Figure 3 As shown, the greenhouse 5 adopts a sloping roof, and the air vent 15 is arranged on the top of the highest side wall.

[0029] The inner and outer sides of the metal plate 13 are painted with anti-corrosion paint, and the anti-corrosion paint is black, red or other colors with high absorptivity and low reflectivity. After the paint is dry, it is polished with coarse sandpaper to eliminate the glossy surface.

[0030] The wall of the greenhouse 5 is provided with a sealed door 10. Specifically, the sealed door 10 is provided on a wall of one side of the greenhouse 5. The sealed door 10 adopts a closed structure.

Install the sealed door 10 on the wall of the hothouse 5.

[0032] The present invention is based on the fact that the greenhouse has the best effect in absorbing solar energy, and proposes that the color of the anti-corrosion paint of the metal plate 13 and the floor paint of the concrete bottom plate 6 is black. When there is an aesthetic requirement, the color can be matched according to the aesthetic requirement, but try to avoid using cold colors or white on a large scale.
