In the aforementioned structure, described sloping core is vertical plane near factory building one side, and the another side of sloping core is the inclined-plane, constitutes thick thin sloping core down.
In the aforementioned structure, be provided with the transport channel that links to each other with a penstock construction hole in the described weight platform.
In the aforementioned structure, described weight platform is provided with one group of joint bar that is connected with factory building base plate, floor or beam steel with sloping core near factory building one side.
In the aforementioned structure, the top of described backfill rock ballast is the road surface that links to each other with incoming highway; The backfill rock ballast is the inclined-plane near earth and rockfill dam one side.
Compared with prior art, the utility model arranges in conjunction with factory building end waterwall, in the power plant building wall-retaining structure is set between earth and rockfill dam, barricade has following major function: the ratchel that 1. prevents the earth and rockfill dam construction rolls into the factory building foundation ditch, guarantees construction of hydropower safety; 2. body of wall can be used as the permanent waterwall body structure of factory building, can save construction investment; 3. body of wall inside arranges a transport channel and penstock construction hole and joins, and makes things convenient for the construction of penstock; 4. wall outer side backfill rock ballast and incoming highway join, and solve factory's traffic problems.The utlity model has the outstanding advantage that a wall is used more, be conducive to shorten the diversion circuit, save construction investment.
Description of drawings.
Fig. 1 is generalized section of the present utility model.
Being labeled as in the accompanying drawing: 1-sloping core, 2-weight platform, 3-transport channel, 4-factory building base plate, 5-constuction joint, 6-sealing sheet, 7-beam steel, 8-rock ballast, 9-earth and rockfill dam, 10-road surface.
The specific embodiment.
The utility model is described in further detail below in conjunction with accompanying drawing, but not as to any restriction of the present utility model.
A kind of base of dam powerhouse of hydropower station wall-retaining structure as shown in Figure 1, comprises the weight platform 2 that is positioned at earth and rockfill dam 9 exterior bottom, and weight platform 2 tops are provided with sloping core 1 near factory building one side, are provided with backfill rock ballast 8 between sloping core 1 and the earth and rockfill dam 9; Weight platform 2 is connected with factory building base plate 4 through constuction joint 5 near factory building one side; Be provided with sealing sheet 6 in the constuction joint 5; Sealing sheet 6 and constuction joint 5 vertical settings.Described sloping core 1 is vertical plane near factory building one side, and the another side of sloping core 1 is the inclined-plane, constitutes thick thin sloping core down.Be provided with the transport channel 3 that links to each other with a penstock construction hole in the described weight platform 2.Described weight platform 2 is provided with one group of joint bar that is connected with factory building base plate 4, floor or beam steel 7 with sloping core 1 near factory building one side.The top of described backfill rock ballast 8 is the road surface 10 that links to each other with incoming highway; Backfill rock ballast 8 is the inclined-plane near earth and rockfill dam 9 one sides.
Implementation process of the present utility model
The utility model in the specific implementation, barricade arranges in conjunction with factory building end waterwall, mainly is made up of interior straight outer oblique sloping core and the weight platform of balance body of wall, sloping core and weight platform are the overall structures that employing concreting forms, internal configurations has reinforcing bar.Sloping core is upright near factory building one side, can make things convenient for the layout of the inner electromechanical equipment of factory building; Sloping core tilts near earth and rockfill dam one side, can increase the resistance of barricade, to increase the stability of barricade.The weight platform is to arrange in the sloping core bottom to earth and rockfill dam one side to extend and have a certain thickness concrete structure, weight platform inside arranges transport channel, weight platform top backfill rock ballast makes end face constitute the road surface that joins with incoming highway, weight platform and backfill rock ballast can increase the resistance of barricade, increase the stability of barricade.At the inner transport channel that joins with a penstock construction hole that arranges of weight platform, weight platform top backfill rock ballast and incoming highway join.
