Description
Technical field
The utility model relates to a kind of structure that makes things convenient for the tunnel maintenance, particularly a kind ofly be applicable to that big-and-middle-sized plant equipment enters the structure of long tunnel maintenance, can be used for the repair and maintenance work of power station diversion tunnel, the repair and maintenance work of the diversion tunnel of especially big capacity, long water channeling type Hydraulic and Hydro-Power Engineering.
Background technology
For the permanent safety that guarantees tunnel structure with satisfy power plant safety operation needs, the diversion tunnel in the Hydraulic and Hydro-Power Engineering generally need be provided with access path, so that regularly carry out the work such as maintenance, inspection, scarfing cinder of tunnel.
General, difference according to project scale, grade, diversion and power pattern and tunnel structure layout, the structural configuration of access path and maintenance mode have following several frequently seen pattern usually: 1. enter maintenance, patrol or utilize the reservoir emptying phase by tunnel inlet gate well air vent, enter maintenance by the tunnel import; 2. the block section that utilizes tunnel construction to prop up the hole is provided with enter hole, mandoor etc. as tunnel emptying access path; 3. the enter hole of ball valve, gate valve such as tube valve etc. who utilizes power station penstock enter hole, water wheels unit is as access path.More than several frequently seen tunnel access path structural configuration pattern in the Hydraulic and Hydro-Power Engineering of having built, especially in, in the long diversion and power system engineering of short diversion and power system or low capacity ripe utilization is arranged, artificial or small mechanical equipment passes in and out tunnel in the time of can making things convenient for tunnel emptying maintenance.But, for big capacity, the Hydraulic and Hydro-Power Engineering of long diversion tunnel, owing to exist tunnel section big, the hole line length, tunnel geological conditions complexity along the line, some tunnel adopts combined bolting and shotcrete as the permanent liner protection structure, factors such as tunnel scarfing cinder workload is big, adopt artificial or when carrying out the tunnel maintenance by small mechanical equipment, operating efficiency is low, overhaul length consuming time, have a strong impact on power station diversion and power benefit, therefore maintenance and the scarfing cinder work that must be correlated with by means of the big-and-middle-sized repair apparatus of necessity, and adopt above-mentioned several frequently seen access path arrangement will be difficult to satisfy the requirement that big-and-middle-sized equipment passes in and out tunnel, need consider the layout of repair apparatus transit passage separately.
Summary of the invention
The technical problems to be solved in the utility model is: for solving the deficiencies in the prior art, propose a kind ofly to be applicable to that big-and-middle-sized plant equipment enters the structure of long tunnel maintenance, can satisfy big-and-middle-sized repair apparatus safety and enter tunnel and overhaul, with the operating efficiency that improves the tunnel maintenance, the diversion and power benefit that guarantees the power station.
The technical scheme that the utility model adopted is: a kind ofly be applicable to that big-and-middle-sized plant equipment enters the structure of long tunnel maintenance, the vertical gate shaft that has diversion tunnel and be connected with diversion tunnel, described gate shaft comprises gate slot, the traffic route and the bridge-type opening and closing device of gate shaft top, and the air vent in gate slot downstream, it is characterized in that: described air vent enlarges arranges that forming a size satisfies the maintenance vertical shaft that big-and-middle-sized repair apparatus passes in and out, built concrete frame around the top of this maintenance vertical shaft, and at this covering prefabricated bridge to be opened/closed above framed bent, described prefabricated bridge and described traffic route join.
Described concrete frame comprises one group of vertical column of arranging, between adjacent each column the connection level to beam.
Be provided with vertical enter hole in the lining shaft of described maintenance vertical shaft periphery.
The beneficial effects of the utility model are: the utility model enlarges layout formation maintenance vertical shaft with the air vent of gate shaft, ventilatory function when this vertical shaft not only has gate opening/closing, and its size can satisfy the turnover of big-and-middle-sized repair apparatus, can shorten the time of tunnel maintenance, thereby guarantee the plant generator benefit; Maintenance vertical shaft top joins with the traffic route of gate shaft by the prefabricated bridge that covers on concrete frame and the framed bent, forms whole traffic aisle, makes things convenient for vehicle, personnel to walk, and satisfy safety requirements; During the tunnel maintenance, can directly utilize the bridge-type opening and closing device of backwater gate to hang out prefabricated bridge, hang in repair apparatus, realize the purpose that conventional gate opening/closing equipment complex utilizes; In the concrete lining of maintenance vertical shaft, the enter hole is set separately, specializes in the maintainer and pass in and out the tunnel use, improved the vertically current safety of the big discrepancy in elevation of maintainer.
