Description
Technical field
The present invention relates to the syndeton and the job practices thereof of each cavern of a kind of underground power house.Be applicable to the underground power house of Hydraulic and Hydro-Power Engineering.
Background technology
The underground power house cavity group is made up of several main caverns and attached cavern usually, connects by attached cavern between each main cavern.Main cavern abutment wall scarcely adopts concrete lining, but adopt flexible support methods such as spraying anchor, for requirements such as the ventilation that guarantees the long-time running of main cavern, heating, later stage adopts damp-proofing wall to separate with crag, prevents that crag from producing the service efficiency that malaria influences the ventilation and air conditioning system of main cavern.In damp-proofing wall, utilize Vierendeel girder to establish outrigger base in addition and solve the crag leakage problem as the gutter.Attached connection cavern generally all adopts the concrete lining structure because of electromechanical equipment layout, traffic and needs attractive in appearance.The lining construction of attached connection cavern is generally built prior to the floor of main cavern, and its lining cutting is extended from structure design to construction all difficulty to main hole direction, makes the lining cutting of attached cavern to flush with crag spray-up line.Correlation sectional view such as Fig. 1, Fig. 2 of floor layer represent in attached connection cavern and the main cavern, and two kinds of situations all show between the gateway opening type concrete lining of the slab and girder of main cavern and attached cavern can't form the interface that can supply to be provided with sealing.Attached cavern mostly is apparatus arrangement passage or traffic aisle, so waterproof, the sealing of connecting portion between each cavern are had relatively high expectations, because the crag of underground chamber can't be accomplished watertight (oozing) because of its characteristic, the crag water body can be along oozing the safe operation that influences the connecting portion electromechanical equipment under the crag and having a good transport service.Simultaneously since the lining cutting of attached cavern be the gateway opening type and only flush with crag spray-up line, bring difficulty for smooth-going linking of the building finishing in the linkage section later stage between attached cavern and damp-proofing wall, influence attractive in appearance.Connection therefore main, attached cavern all seems from aspects such as structure, waterproof, construction and finishings and is even more important.
Summary of the invention
The technical problem to be solved in the present invention is: provide a kind of simple, rationally, the syndeton and the job practices thereof of each cavern of underground power house reliably, be intended to make connected structure between each cavern can accomplish smooth-going, waterproof, be convenient to the later stage building finishing.
The technical solution adopted in the present invention is: the syndeton of each cavern of a kind of underground power house, have main cavern and attached cavern, on the crag of main cavern concrete spray coating is arranged, between main cavern and concrete spray coating damp-proofing wall is set, in the attached cavern concrete lining is arranged, it is characterized in that: be connected the both sides, fork in main cavern with attached cavern and be close to crag concrete spray coating layout side column, the edge of side column flushes with concrete lining and damp-proofing wall outer edge, be the prolate type, arrange a profiled beam in attached cavern crown elevation in that two side columns are upper, the top edge of this beam or lower limb are optimized for the shaped form with attached cavern's crown lining cutting inward flange unanimity, the deck-siding of profiled beam equals the distance between main cavern crag concrete spray coating and damp-proofing wall outer edge, top at profiled beam is provided with the gutter, and the interface that is in the combination of side column and profiled beam and attached cavern between the concrete lining of gateway opening type is laid the border waterstop.
The edge of described profiled beam is optimized for the shaped form with attached cavern's crown lining cutting inward flange unanimity, utilizes the combination of side column and profiled beam to lay the border waterstop with the abundant interface between the gateway opening type concrete lining in the attached cavern.
The job practices of each cavern's syndeton of a kind of underground power house is characterized in that may further comprise the steps:
1) be connected the both sides, fork with attached cavern in main cavern and be close to crag concrete spray coating layout side column, the edge of side column flushes with concrete lining and damp-proofing wall outer edge, and side column is the prolate type;
2) arrange a profiled beam in attached cavern crown elevation in that two side columns are upper, this profiled beam is that local increasing of the damp-proofing wall underbeam of main cavern formed, and the local deck-molding that strengthens section should be able to realize that profiled beam and attached cavern's lining cutting crown have sufficient interface;
3) interface that is in the combination of side column and profiled beam and attached cavern between the concrete lining of gateway opening type is laid the border waterstop;
4) at the top of profiled beam the gutter is set.
The job practices of another kind of each the cavern's syndeton of underground power house of the present invention is characterized in that may further comprise the steps:
1) be connected the both sides, fork with attached cavern in main cavern and be close to crag concrete spray coating layout side column, the edge of side column flushes with concrete lining and damp-proofing wall outer edge, and side column is the prolate type;
2) arrange a profiled beam in attached cavern crown elevation in that two side columns are upper, this profiled beam arranges that independently the section of profiled beam and side column has the sufficient interface except that satisfying with the inner concrete lining cutting of attached cavern, also should be able to bear the load of damp-proofing wall above the profiled beam;
3) interface that is in the combination of side column and profiled beam and attached cavern between the concrete lining of gateway opening type is laid the border waterstop;
4) at the top of profiled beam the gutter is set.
The invention has the beneficial effects as follows: the technical program is main in conjunction with utilizing, the design of attached cavern structural configuration, engineering measure is simple, easy construction, syndeton rationally, simply, reliably make the connection of each cavern realize smooth-going linking, waterproof sealing, are convenient to the later stage building finishing.
