Specific embodiment
The arrangement form of the utility model is further described below in conjunction with the accompanying drawings.As shown in figures 1-4, figure is included into factory
Access tunnel 1, underground power house lower floor collector drain 2, fan house 3, air duct 4, underground chamber 5, factory become transport hole 6, and collector drain is simultaneous
Into wind-tunnel 7, anchor pole 8, spray C20 concrete layers 9, collector drain underplate concrete layer 10, gutter 11, the blind 12 (outsourcing of material of draining
Geotextiles), side-top arch concrete lining cutting layer 13,14- drainage ditch cover plates.
Underground power house collector drain described in the utility model is also served as to be included the following steps into wind-tunnel：
The first step, with reference to the underground power house structure chart in Fig. 1, by research than choosing, underground power house lower floor collector drain 2 exists
The elevation of 3 position of fan house is substantially consistent with into wind-tunnel, by reducing the elevation of underground power house lower floor collector drain 2, to meet
Collector drain and the elevation condition into wind-tunnel 7, while substitute former into wind-tunnel arrangement.
Second step digs the underground power house lower floor collector drain 2 also served as into wind-tunnel section, it is made to meet air inlet wind speed requirement,

The blind material 12 of draining of geotextiles and fixed, blind 12 port of export of the material introducing gutter 11 of draining are wrapped up；
4th step carries out coagulation to collector drain and into the surface (i.e. hole inner surface, the blind material 12 of covering draining) of wind-tunnel 7
Native lining cutting forms side-top arch concrete lining cutting layer 13；
5th step is drained to subdrainage by collector drain and into the infiltration of 7 palisades of wind-tunnel by the blind material 12 of draining secretly buried
Ditch 11.
6th step, gutter 11 add drainage ditch cover plate 14, the purpose is to prevent moisture evaporation, reduce the sky into wind turbine
Air humidity degree.
By the way that underground chamber lower floor collector drain is transformed, it is made to substitute into wind-tunnel, it can be achieved that " hole is mostly used ", saves engineering
Investment；By expanding collector drain and into wind-tunnel section cross-sectional area, can make to meet the requirements into wind tunnel speed；By the way that draining corridor is transformed
Drainage by open canal ditch in road is the ditch that underdrains, and carries out concrete lining to collector drain and into the surface of wind-tunnel, by collector drain
Palisades infiltration drains into mole drain by the blind material of draining secretly buried, can reduce air humidity.So the underground chamber takes wind side
Method, it is easy to implement, it is easy to spread.
