Detailed description of the invention
Below in conjunction with accompanying drawing, technical solution of the present invention is described in detail, but protection scope of the present invention is not limited to described embodiment.
Embodiment 1:
As Figure 1-5, base plate decompressor of the present invention comprises reducing valve and drainage pipeline.
Wherein, drainage pipeline is made up of cylindrical tube 6, cone barrel water inlet 7 and the water strainer 8 be sealed on cone barrel water inlet 7; The lower port of cylindrical tube 6 and the vertex of a cone of cone barrel water inlet 7 are docked and connected; The upper port of cylindrical tube 6 and the water inlet of reducing valve are docked and connected by connecting thread 4 screw thread; The outer wall of cylindrical tube 6 is provided with a ring shape seal plate 5, and the axis perpendicular of the plate face of ring seal plate 5 and cylindrical tube 6; The cone bottom diameter of cone barrel water inlet 7 is 400 ~ 600mm, and the conical degree of conical surface of cone barrel water inlet 7 is 50 ° ~ 70 °;
Reducing valve comprises valve body 1, water out adapter 2 and connecting pipe 3; The upper port of connecting pipe 3 is connected with the water inlet of valve body 1; The lower port of connecting pipe 3 and the upper port screw thread of cylindrical tube 6 are docked and connected; Water out adapter 2 is connected with the delivery port of valve body 1.
As shown in Figure 4, when foundation ditch is provided with dewatering well 9, be provided with a ring shape formwork seal plate 11 in the outside at the lower port of cylindrical tube 6 and the vertex of a cone place of being docked and connected of cone barrel water inlet 7.
Before use, the thickness whether arranging dewatering well 9 and base plate 10 according to foundation ditch determines the permanent position of the size of cone barrel water inlet 7, the length of cylindrical tube 6 and ring seal plate 5 to base plate decompressor of the present invention.
If be provided with dewatering well 9 in foundation ditch, after foundation ditch bed course 12 is built, dewatering well 9 is blocked the absolute altitude to foundation ditch bed course 12 top, the cone barrel water inlet 7 of decompressor is stretched in dewatering well 9, the position of adjustment decompressor, makes the bottom of the water out adapter 2 of reducing valve be in 3/5ths height and positions of base plate 10; Be sealed on the well head of dewatering well 9 with annular template sealing plate 11 again, thus to sealing gap; Turn the handwheel on valve body 1 again, thus close reducing valve; Before reinforcing bar binding, install box body template in the bottom of the water out adapter 2 of reducing valve, long 1m, wide 1m, be highly 3/5ths bottom plate heights and reinforce, after building, be the size of reserved hole body, ensure that reducing valve is not shut by concrete.
If do not have dewatering well 9 in foundation ditch, before foundation ditch bed course 12 is built, be embedded in by decompressor in foundation ditch bed course 12, the top of cone barrel water inlet 7 is the elevation of top of foundation ditch bed course 12; Before reinforcing bar binding, install box body template in the bottom of the water out adapter 2 of reducing valve, length is 1m, and width is 1m, is highly 3/5ths bottom plate heights and reinforces, and is the size of reserved hole body after building, and ensures that reducing valve is not shut by concrete.
After concreting, rotate the handwheel on valve body 1, open reducing valve, manage with the PE of snap joint the dark sump that (caliber is 75mm) connect water out adapter 2 to the periphery on reducing valve with end, if water level rising, water can flow directly in sump.
After main body construction terminates, during according to designing requirement stopping precipitation, turn the handwheel on valve body 1, close reducing valve, surface, hole concrete dabbing will be reserved, close with the microdilatancy water-tight concrete of a label higher than the concrete of former base plate 10.
As mentioned above, although represented with reference to specific preferred embodiment and described the present invention, it shall not be construed as the restriction to the present invention self.Under the spirit and scope of the present invention prerequisite not departing from claims definition, various change can be made in the form and details to it.
