Abstract
The present invention relates to a hydraulic self-controlling water drainage structure of a bottom plate of a force-eliminating pond, which solves the problem of high cost in the existing structural engineering. The structure has the technical scheme that drainage holes are arranged on the bottom plate of the force-eliminating pond, and hydraulic self-controlling drainage valves composed of sleeve barrels, floating covers and braking top covers are buried inside the drainage holes; the sleeve barrels are inlaid inside the drainage holes, and the inner walls of the sleeve barrels are provided with through slide ways; sliding chutes matched with the floating covers are arranged on the floating covers and are positioned inside the sleeve barrels; the braking top covers are fixed above the sleeve barrels and are provided with braking feet of the floating covers. The bottom of the force-eliminating pond in the structure of the present invention does not need to be built with lots of drainage tunnels, large-scale drainage galleries or deep wells, which can save a large quantity of manpower, material resources, financial power and time. Each bottom plate only needs one or two drainage holes, which gets construction convenient and quick. The drainage valves are prefabricated members and are convenient for field installation. The drainage valves can sense the water head over 3.4cm, when the uplifting pressure is greater than the water head, the floating covers automatically get opened and release pressure, which is sensitive and quick in reaction. The present invention is convenient in operation and maintenance, and is simple and convenient in replacing the drainage valves.

[specific embodiment]:
Embodiment 1
As shown in Figure 1, 2, the present invention is achieved through the following technical solutions: when building the plunge pool concrete, reserve 1 to 2 concrete drain hole 3 that diameter is 9.5～19.5cm on the every base plate 1, the degree of depth be from the ground basal plane to the downward 10～20cm of distance plate upper surface, the plan-position is base plate centre of form place or axis 1/3rd and 2/3rds places.Above the concrete drain hole, bury a waterpower self-control draining valve 2 underground, high 10～20cm; This draining valve is steel prefabricated units (also can be made by other material that is difficult for getting rusty), is made up of three parts: steel bushing, floating cover and braking top cover.
Internal diameter 11～the 21cm of steel bushing (shown in Fig. 3,4), sleeve wall 6 thick 0.5cm; Its vertical section is
Type, promptly the bottom have one inwardly turn over along 5, the internal diameter on edge is identical with the internal diameter of concrete drain hole, i.e. 9.5～19.5cm, thick 0.5cm; Its upper limb has rotation holddown groove 7, the outer wall dome-type projection 8 that distributing brokenly, purpose be for concrete in conjunction with firmly; Sleeve lining has the slideway 9 (N gets 4, also desirable any natural number more than 2) of 4 perforations herein, to inner process 0.75cm, and wide 0.5cm.
Floating cover (shown in Fig. 5,6) is that diameter is the collar plate shape member of 10～20cm, and thick 0.5cm is having 4 chutes 10 that 0.25cm is dark with the corresponding position of slideway; The thick 0.5cm of braking top cover (shown in Fig. 7,8), braking top cover outer rim is provided with the fixed claw 11 that cooperates with rotation holddown groove on the sleeve, fixed claw is inserted in the rotation holddown groove on the sleeve, rotation can be fixed on the braking top cover on the sleeve then, the inboard of braking top cover is provided with 4 and is used for the spacing braking pin 12 of floating cover (M gets 4, also desirable any natural number more than 2) herein.
Because the slit 4 of 0.5cm is arranged between steel bushing internal diameter and the steel lid, when the uplift pressure of base plate soffit during greater than the buoyant weight of steel lid, the steel lid is opened release pressure automatically; When uplift pressure during less than the buoyant weight of steel lid, the steel lid falls, and with the sealing of concrete drain hole, prevents that plunge pool high speed current from damaging the concrete drain hole.
Preferred forms
Adopt the long 9m of single plate of the plunge pool base plate of this waterpower self-control discharge structure, wide 9m, thick 4m.The concrete drain hole of one internal diameter 9.5cm is arranged at the centre of form place of plate, and the upper surface of concrete drain hole is apart from plate upper surface 10cm.Waterpower self-control draining valve internal diameter 11cm, high 10cm, steel cover thick 0.5cm.Be embedded in concrete drain hole top from control draining valve, can bear the uplift pressure head of 6m when base plate does not add the reinforcing bar anchoring, and when the uplift pressure head surpassed 3.4cm, the steel lid opened release of pressure automatically.As seen the uplift pressure that can bear much smaller than base plate of Ci Shi uplift pressure is so this waterpower self-control discharge structure draining release of pressure effect is obvious.
