Internal drainage system of described factory comprises branch drain that is connected with the draining blind pipe net port of export and the leader drain that is connected with branch drain, and collecting well or gutter are connected in leader drain and the factory.
Described branch drain gos deep into blind pipe 10mm.
Described draining blind pipe net is made of interconnective some horizontal drainage blind pipes and some vertical drainage blind pipes.
The job practices of the discharge structure of upstream wall of shore type hydropower station workshop of the present invention comprises the construction of bottom discharge system and the construction of top drainage system, and step is as follows:
I) construction of bottom discharge system,
A) before the concrete structure construction of the bottom of factory building head bay wall, in rock, make a call to earlier one group of drain hole, hole depth 5.0m, pitch-row 2.0m.
B) the horizontal drainage blind pipe is laid in the position of corresponding drain hole, the vertical drainage blind pipe is installed again each horizontal drainage blind pipe is coupled together, and constitutes draining blind pipe net; With tin plate and cement nail this draining blind pipe net is fixed in rock surface.
C) before the bottom concrete structure is built, the position of corresponding bottom draining blind pipe is laid branch drain in advance; Branch drain gos deep into blind pipe 10mm; The branch drain port of export is connected with leader drain by threeway, and the port of export of leader drain connects collecting well or gutter.
D) build the bottom concrete structure.
The ii) construction of top drainage system,
E) before the top of head bay wall concrete structure is built, lay branch drain in advance, the port of export of branch drain connects leader drain by threeway; The outlet termination collecting well or the gutter of leader drain.
F) build the top concrete structure, and be coated with the last layer water-repellent paint, remove branch drain import foreign material at the wall face of top concrete structure.
G) wall face at the top concrete structure lays the draining blind pipe net that is made of horizontal drainage blind pipe and vertical drainage blind pipe, and the blind pipe of the blind pipe net bottom links to each other with the import of branch drain, and branch drain gos deep into blind pipe 10mm; With tin plate and cement nail draining blind pipe net is fixed.
H) backfill rock ballast between top concrete structure and rock.
The invention has the beneficial effects as follows: at the geological condition of factory building head bay wall position, bottom and top two cover drainage systems are set respectively, make the underground water of upstream enter gutter or collecting well by this discharge structure smoothly, effectively reduced the upstream groundwater table, prevent that underground water infiltration factory building body of wall is inner and cause the calcareous of its structural concrete to be separated out thereupon, thereby the intensity and the durability of wall body structure have been guaranteed, for the power station provides good running environment.
