The utility model discloses adapt to any quality of water, ability automatic drainage need not manual operation, labour saving and time saving.
Description
Technical field
This utility model belongs to drainage arrangement technical field in hydraulic engineering, and especially a kind of rubber and plastic folds the unidirectional automatic drain valve of sealing chip.
Background technology
Along with freshwater resources are the most in short supply, channel and Wall in Plain Reservoir construction, for preventing filter loss, getting more and more and have employed all kinds of seepage control technique, though efficiently solving antiseepage, but also counteracts that the row of subsoil water oozes out road simultaneously.When level of ground water is higher than channel and Plain reservoir level, acting on bottom and domatic uplift pressure raises, there are the breakoff phenomenons such as large area panel spring, bulge cracking in impervious barrier.In order to eliminate this destruction, major part engineering have employed the single slope drainage valve of mechanical type or float-ball type, exists dumb, fragile, by problems such as water quality impacts in actual application.For this situation, we have developed without manual operation, not by water quality impact, mechanical and electronic equipments, performance single slope drainage valve flexible, reliable.
Summary of the invention
For under certain condition, level of ground water outside water level is less than channel or Wall in Plain Reservoir in channel or Wall in Plain Reservoir, the uplift pressure jacking of canal lining impervious barrier, Wall in Plain Reservoir impervious barrier can be destroyed problem by subsoil water, and this utility model provides a kind of rubber and plastic to fold the unidirectional automatic drain valve of sealing chip.Realizing technical solution adopted in the utility model is: a kind of rubber and plastic folds the unidirectional automatic drain valve of sealing chip, it is characterized in that: this unidirectional automatic drain valve is folded sealing piece by hourglass shape rubber and plastic with holes, top board, first trocar sheath, inner sleeve, second trocar sheath and quartz sand composition, hourglass shape rubber and plastic with holes folds sealing piece and is provided with spilled water hole, hourglass shape rubber and plastic with holes folds sealing piece top with top board by glue seamless link, hourglass shape rubber and plastic with holes is folded sealing piece bottom and is connected by draw-in groove with the first trocar sheath, the top and bottom of inner sleeve are inserted in the first trocar sheath and the second trocar sheath respectively, the length of inner sleeve determines according to impervious barrier thickness, second trocar sheath is internal places quartz sand, second outer sleeve bottom arranges inlet opening.Described top board uses rubber and plastic to make, and described the first trocar sheath, inner sleeve and the second trocar sheath all use ABS plastic to make.
This utility model have light weight, simple in construction, mechanical or electronic device, performance flexibility and reliability, be hardly damaged, the feature such as ageing resistance is strong, adapt to any water quality simultaneously, energy Auto-drainage, without manual operation, time saving and energy saving, it is widely portable to the draining of the impervious body of various hydraulic structure, prevents uplift pressure from destroying.

Detailed description of the invention
Referring to the drawings, a kind of rubber and plastic folds the unidirectional automatic drain valve of sealing chip, it is characterized in that: this unidirectional automatic drain valve is folded sealing piece 1 by hourglass shape rubber and plastic with holes, top board 2, first trocar sheath 4, inner sleeve 5, second trocar sheath 6 and quartz sand 7 form, hourglass shape rubber and plastic with holes folds sealing piece 1 and is provided with spilled water hole 3, hourglass shape rubber and plastic with holes folds sealing piece 1 top with top board 2 by glue seamless link, hourglass shape rubber and plastic with holes is folded sealing piece 1 bottom and is connected by draw-in groove 11 with the first trocar sheath 4, the top and bottom of inner sleeve 5 are inserted in the first trocar sheath 4 and the second trocar sheath 6 respectively, the length of inner sleeve 5 determines according to the thickness of impervious barrier 9, second trocar sheath 6 is internal places quartz sand 7, second outer sleeve bottom arranges inlet opening 8.Described top board 2 uses rubber and plastic to make, and described the first trocar sheath 4, inner sleeve 5 and the second trocar sheath 6 all use ABS plastic to make.
Work process of the present utility model is: generally, drain valve is in the state of accompanying drawing 3, hourglass shape rubber and plastic with holes fold sealing piece 1 two panels pressing, hourglass shape rubber and plastic the most with holes fold sealing piece 1 can sealing, make outside water can not enter channel or Wall in Plain Reservoir impervious barrier 9.When level of ground water outside water level is less than channel or Wall in Plain Reservoir in channel or Wall in Plain Reservoir, accompanying drawing 1 and the state of accompanying drawing 2 it is under drain valve hull-borne, subsoil water filters through quartz sand 7, arrive unidirectional automatic drain valve, water pressure in drain valve and the elastic force of hourglass shape rubber and plastic with holes folding sealing piece 1, jointly top board 2 is pushed open, water is discharged by the spilled water hole 3 that hourglass shape rubber and plastic the most with holes folds on sealing piece 1, reduce outside level of ground water, gradually alleviate uplift pressure, the uplift pressure of outside is finally completely eliminated.
