Abstract
The utility model discloses a kind of discharge structure of tailwater tunnel working tunnel, it is in conjunction with underground power house collector drain combined layout; Comprise tailwater tunnel working tunnel and underground power house lower floor collector drain, be embedded with drainage pipe in the occluding body of described tailwater tunnel working tunnel, described tailwater tunnel working tunnel is communicated with described underground power house lower floor collector drain.Solve the runtime draining of tailwater tunnel working tunnel, avoiding forming ponding Construction unit in runtime working tunnel cannot patrol; Avoid setting working tunnel being re-started to draining evacuation system, save engineering operation expense.
Description
Technical field
The utility model relates to Hydraulic and Hydro-Power Engineering technical field, particularly relates to a kind of pumped storage underground power house tailwater tunnel working tunnel discharge structure.
Background technology
Pumped storage hydropower plant tailwater tunnel is constructed, and generally for the engineering that tailwater tunnel is longer, need arrange the construction passage of working tunnel as tailwater tunnel.And for the working tunnel of tailwater tunnel, be all that hole is high, in hole the end, and thus construction period draining often adopts interim sump and water pump evacuation system in hole to solve.Enter the runtime at completion of works, after interim evacuation system is withdrawn, working tunnel is without effective discharge structure, easily ponding is formed in a hole, run unit cannot carry out scene inspection, and the later stage rearranges the comparatively complicated difficulty of evacuation system again, and investment is larger.
Utility model content
The purpose of this utility model is the discharge structure providing a kind of tailwater tunnel working tunnel, thus solves the foregoing problems existed in prior art.
To achieve these goals, the technical solution adopted in the utility model is as follows:
A kind of tailwater tunnel working tunnel discharge structure, in conjunction with underground power house collector drain combined layout; Comprise tailwater tunnel working tunnel and underground power house lower floor collector drain, be embedded with drainage pipe in the occluding body of described tailwater tunnel working tunnel, described tailwater tunnel working tunnel is communicated with described underground power house lower floor collector drain.
Preferably, described tailwater tunnel working tunnel is communicated with by underground power house lower floor collector drain extension or linkage section with described underground power house lower floor collector drain.
Preferably, described pipeline is steel pipe.
Preferably, described steel pipe is the steel pipe of DN200mm.
The beneficial effects of the utility model are:
(1) solve the runtime draining of tailwater tunnel working tunnel, avoiding forming ponding Construction unit in runtime working tunnel cannot patrol; (2) avoid setting working tunnel being re-started to draining evacuation system, save engineering operation expense.
Accompanying drawing explanation
Fig. 1 is the floor map of tailwater tunnel working tunnel discharge structure of the present utility model;
Wherein: 1---tailwater tunnel working tunnel; 2---embedded steel tube 3---block section; 4---lower floor collector drain extension (linkage section); 5---underground power house lower floor collector drain; 6---collecting well; 7---tailwater tunnel; 8---factory building bottom working tunnel.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with accompanying drawing, the utility model is further elaborated.Should be appreciated that detailed description of the invention described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, the utility model discloses a kind of discharge structure of tailwater tunnel working tunnel, it is in conjunction with underground power house collector drain combined layout; Comprise tailwater tunnel working tunnel and underground power house lower floor collector drain, be embedded with drainage pipe in the occluding body of described tailwater tunnel working tunnel, described tailwater tunnel working tunnel is communicated with described underground power house lower floor collector drain.Described tailwater tunnel working tunnel is communicated with by underground power house lower floor collector drain extension or linkage section with described underground power house lower floor collector drain.Described pipeline is steel pipe.By the infiltration of tailwater tunnel working tunnel country rock discharged to factory building lower floor collector drain extension or linkage section, finally enter factory building collecting well or Artesian Drainage water hole.
1 further illustrate by reference to the accompanying drawings for certain large pumped storage power plant that have employed technical solutions of the utility model below:
Certain pumped storage power plant tail water tunnel construction layout of adits is in tailwater tunnel adit section, tailwater tunnel working tunnel is in conjunction with factory building bottom working tunnel combined layout, tailwater tunnel working tunnel low spot is positioned at tailwater tunnel adit section, and the construction period adopts interim sump and water pump evacuation system in hole to carry out draining.Runtime discharge structure is in conjunction with underground power house lower floor collector drain combined layout, lower floor's collector drain is extended to tailwater tunnel working tunnel from underground power house, at the draining steel pipe of the pre-buried DN200mm in working tunnel block section, by the infiltration of tail water working tunnel country rock discharged to underground power house lower floor collector drain extension, finally enter factory building collecting well.
By adopting technique scheme disclosed in the utility model, obtain effect useful as follows:
(1) solve the runtime draining of tailwater tunnel working tunnel, avoiding forming ponding Construction unit in runtime working tunnel cannot patrol; (2) avoid setting working tunnel being re-started to draining evacuation system, save engineering operation expense.
The above is only preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should look protection domain of the present utility model.
