Abstract
The utility model discloses a kind of hydropower station construction ventilation well construction, relate to hydraulic engineering field, a kind of hydropower station construction ventilation well construction that can not take intake tower tower body top usable floor area is provided.Hydropower station construction ventilation well construction comprises tower body and tunnel, is provided with ventilation well in tower body, and ventilation bottom is communicated with tunnel, and the well head of ventilation well is positioned at tower body top, and ventilation well quantity is two, and the well head of two ventilation wells lays respectively at tower body both sides.Power station intake tower ventilation well construction also can comprise windbreak, and windbreak is arranged at tower body top and around well head.Logical gas well mouth of the present utility model can not take intake tower tower body top usable floor area, and the work in every being conducive to carrying out to tower body top offers convenience; Foreign material amount is easily sucked when can also reduce the ventilation of ventilation well to a certain extent.
Description
Technical field
The utility model relates to hydraulic engineering field, especially designs a kind of hydropower station construction ventilation well construction.
Background technology
Hydropower station construction structure as shown in Figure 1, arranges Emergency Gate in tower body, and the tunnel of spreading, then connects working radial gate.Ventilate well after Emergency Gate, on the side wall of gate shaft, from tunnel one through to crest elevation.During maintenance, open working radial gate and to release hole internal water accumulation, by ventilation well toward tonifying Qi in tunnel, such ponding could steadily flow out.After having overhauled, Emergency Gate cuts out, and generally by arranging bypass pipe at gate shaft side, if time dash head is not high, directly can also arrange movable wicket on Emergency Gate, gives the bath of flood discharging tunnel below.At this time working radial gate is closed, and the air in tunnel can only be discharged outward by ventilation well, if discharge not in time, can form air bag, affect flood discharge safe operation in hole.
The effect of well of ventilating as shown in the above is ventilation or discharge air in tunnel in tunnel.Existing ventilation well is vertically arranged, and the well head of its upper end is positioned at the centre at intake tower top, and take the usable floor area that tower body top is limited, the work in every carried out to tower body top is made troubles.In addition, because of unshielded measure, during the ventilation of ventilation well, easily foreign material are sucked.
Utility model content
The technical problems to be solved in the utility model is: provide a kind of hydropower station construction ventilation well construction that can not take intake tower tower body top usable floor area.
In order to solve the problem, the technical scheme adopted is: hydropower station construction ventilation well construction comprises tower body and tunnel, ventilation well is provided with in tower body, ventilation bottom is communicated with tunnel, the well head of ventilation well is positioned at tower body top, ventilation well quantity is two, and the well head of two ventilation wells lays respectively at tower body both sides.
Further: hydropower station construction ventilation well construction comprises windbreak, and windbreak is arranged at tower body top and around well head.
The beneficial effects of the utility model are: the well head of two ventilation wells is laid respectively at tower body both sides, then well head can not take intake tower tower body top usable floor area, and the work in every being conducive to carrying out to tower body top offers convenience.
Accompanying drawing explanation
Fig. 1 is hydropower station construction ventilation well construction longitdinal cross-section diagram;
Fig. 2 is hydropower station construction ventilation well construction top view;
Fig. 3 is hydropower station construction ventilation well construction view in transverse section;
Be labeled as in figure: tower body 1, ventilation well 2, gate shaft 3, Emergency Gate 4, tunnel 5, working radial gate 6, well head 7, windbreak 8.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is further illustrated.
Hydropower station construction ventilation well construction comprises tower body 1 and tunnel 5, be provided with ventilation well 2 in tower body 1, be communicated with bottom ventilation well 2 with tunnel 5, the well head 7 of ventilation well 2 is positioned at tower body 1 top, ventilation well 2 quantity is two, and the well head 7 of two ventilation wells 2 lays respectively at tower body 1 both sides.
The well head of two ventilation wells is laid respectively at tower body both sides, then well head can not take intake tower tower body top usable floor area, and the work in every being conducive to carrying out to tower body top offers convenience.
The shape of ventilation well 2 can be as shown in Figure 3.
Easily suck foreign material amount to reduce when ventilation well 2 is ventilated, hydropower station construction ventilation well construction comprises windbreak 8, and windbreak 8 is arranged at tower body 1 top and around well head 7.Windbreak 8 can enter ventilation well 2 by stop portions foreign material, easily sucks foreign material amount when reducing the ventilation of ventilation well to a certain extent.
