Abstract
The utility model provides a pressure reducer for preventing the seepage of an irrigation ditch. A hole (2) is drilled on the soleplate of a circular sleeve barrel (1) provided with a rubber gasket (3) and an anti-seepage film (4), and the rubber gasket (3) and the anti-seepage film (4) are positioned by elastic bodies (5). The two ends of the circular sleeve barrel (1) are wrapped by filtering materials and are inserted into anti-seepage layers, gumming dirt is used for the seepage of water between seams, the seeped water on the bottom of a mountain slope is led into irrigation ditches, and the water in the irrigation ditches can not seep. The utility model provides a protecting device for the anti-seepage layers of the irrigation ditches.
Description
The utility model relates to the protective device of anti-seepage of channels layer usefulness in a kind of hydraulic engineering, is a kind of anti-seepage of channels pressure reducer.
In hydraulic engineering, for guaranteeing safety and using water wisely, concrete commonly used or gentle felt etc. are at channel surface construction impervious barrier.For winding channel, during non-irrigation season,, often make concrete anti-seepage layer cracking because hillside water following oozes effect; Impervious barriers such as gentle felt drum occurs and break through bad phenomenon, influence anti-seepage effect.
General way is to build the gutter below anti-seepage of channels layer in advance, and engineering quantity is big like this, cost is high, infiltration can not reclaim and silt up easily, be difficult to safeguard under the hillside.
The purpose of this utility model is to overcome above-mentioned deficiency, with its bottom, canal limit that is installed in anti-seepage of channels layer backer slope, makes impervious barrier and this device non-leakage under the channel internal water pressure; And can eliminate the destroying infection of infiltration under the hillside, play the effect of protection impervious barrier.
The utility model is achieved in that in base plate garden sleeve with holes, and rubber gasket and impervious glued membrane are installed, and is putting elastic body on it, and wrap up with filtering material at the two ends of garden sleeve.
Structure and use below in conjunction with the description of drawings utility model.
Fig. 1 is the longitudinal plan of utility model.
Fig. 2 is the behavior in service figure of utility model.
With reference to Fig. 1, the garden sleeve (1) of a band base plate, height is suitable with impervious barrier thickness, and about 2～3 centimetres of internal diameter adopts duroplasts or metal to make; Have a hole (2) on the base plate, about 5～7 millimeters of diameter; Be close to rubber gasket (3) on the base plate, the impervious glued membrane of a slice (4) is housed on it, they all make thick about 1 millimeter with dripping glue; Gently pressing elastic body (5) stoping its dislocation on impervious glued membrane (4), material can be with geotextile or sponge; The two ends of garden sleeve (1) are inserted in the impervious barrier preformed hole with the wrapping of filtering material (6) geotextile afterwards, use clay (7) sealing between seam.
Under the water effect, impervious glued membrane (4) and rubber gasket (3) are pushed against on base plate together in channel, and hole (2) can not seep water; Under the effect of seeping water under the hillside, impervious glued membrane (4) is separated by jack-up and rubber gasket (3) and base plate, and seeping water down in the hillside, (2) enter in the channel through the hole, play depressurization.
This device can prevent effectively that the drum of the cracking of concrete canal impervious barrier and gentle felt anti-seepage of channels layer from breaking through badly, reaches the purpose of safe water-saving.
Claims (4)
1, a kind of anti-seepage of channels pressure reducer is characterized in that: be close to rubber gasket (3) on (2) with holes of garden sleeve (1) base plate, impervious glued membrane (4) is housed above, pressing elastic body (5) on it, wrap up with filtering material (6) at the two ends of garden sleeve (1).
2, according to the device of claim 1 defined, it is characterized in that: garden sleeve (1) adopts duroplasts or metal to make.
3, according to the device of claim 1,2 defineds, it is characterized in that: rubber gasket (3) and impervious glued membrane (4) all adopt a glue to make.
4, according to the device of claim 1 defined, it is characterized in that: elastic body (5) and filtering material (6) can adopt geotextile or sponge.
