Description

A kind of portable piping device of speedily carrying out rescue work fast

Technical field:

The utility model relates to a kind of hydraulic engineering equipment that flood-fighting is used that is used for, especially a kind of device of speedily carrying out rescue work fast that is used for piping.

Background technology:

Piping is the dangerous situation of a kind of flood season to river dyke safety formation significant threat, also is dangerous situation common in the flood fighting.Piping is exactly after the weak part of weak permeable loam in top layer or mucky soil is worn on the artesian water top of permeable sand-layer foundation, the destruction that concentration of local seepage flow forms is taken place, at this moment, surface soil layer has formed a permeable cavity, the soil particle of permeable layer of sand is with the infiltration current hole that constantly gushes out, and similar change diameter is ducted holds the sand water movement under the arm.The size in piping aperture, the flow velocity of holding the sand current under the arm and sand content are all decided on seepage gradient, earth formation and sand grains particle diameter.Therefore, when rescuing and protecting the piping dangerous situation, also consider to hold under the arm factor such as entrained gravel particle diameter and layering water conservancy diversion in the kinetic head, current of sand current except that the factor of considering the failure by piping filtering layer is, the current that changed when preventing usually that piping from taking place flow shape.More than preventing common failure by piping filtering layer complexity.For now, also there is not a kind of simple, reliable piping governing measure.Usually after can only waiting until that piping occurs, rescue and protect, the piping dangerous situation of rescuing and protecting is removed commonly used enclosing the well, and another kind of effective measures are filter blanket, and it act as and reduces the water burst flow velocity, prevents the sand grains loss, to stablize the piping dangerous situation; The normal filter blanket that adopts of technology has sandstone filter blanket, tip material filter blanket and geotextile filter blanket now.Three kinds of schemes of technology all need the implementer to accept the training of this respect in advance now, and need certain practical experience.Simultaneously, these three kinds of technology all need at the scene bedding length by length, and speed is slow, does not satisfy the actual needs of racing against time in the flood fighting scene, affects good opportunity of combat easily adversely.

Summary of the invention:

The purpose of this utility model provides and a kind ofly can manufacture, guarantor's sand easy to carry, permeable and the effect of the dissipation flow of water obviously, the piping that can use the repeatedly device of speedily carrying out rescue work fast.

The technical scheme that the utility model adopted is: the main body of the device of speedily carrying out rescue work fast is that a semiclosed cylinder and some drill rods constitute, one end of its semiclosed cylinder is uncovered, the other end has the semiclosed of some osmotic pressures hole, cylinder is distributed with some drill rod earrings outward, the drill rod earrings is distributed on the same cross section, like this drill rod earrings to the cylinder opening end for going into ground cofferdam tube, drill rod earrings to semiclosed end is the osmotic pressure cylinder; Osmotic pressure cylinder inner structure has the three layers of formation that stacks together from inside to outside, first floor is the osmotic pressure adjustment disk, the osmotic pressure adjustment disk is concentric with the osmotic pressure cylinder, diameter equates with osmotic pressure cylinder interior diameter or is smaller, also distribute and the corresponding osmotic pressure of osmotic pressure cylinder hole on the osmotic pressure adjustment disk, also have some regulating handles on the osmotic pressure adjustment disk; The second layer is a coil of wire, and the coil of wire size is identical with the osmotic pressure adjustment disk, and coil of wire is fixed in the osmotic pressure cylinder by a pressure ring; The 3rd layer is geotextile cloth, shape, the size suitable with coil of wire, by the steel wire flexible fastening in the osmotic pressure cylinder.

Can substitute by an annulus pressing plate as the drill rod earrings described in the device that the portable piping of its improvement is speedily carried out rescue work fast, can open several drill rod holes on the annulus pressing plate; Can also there be some upper and lower reinforcing ribs annulus pressing plate and osmotic pressure cylinder junction.

Because it is that topping, the 3rd layer of geotextile cloth are that filtration beds constitutes that the portable piping of the utility model is speedily carried out rescue work in the device by promptly reduce pressure layer, second layer coil of wire of first floor osmotic pressure adjustment disk fast.The trilaminate material formation that stacks together.Form certain intensity, have filtering function, water permeability better again silt.First floor mainly is to regulate water flow and pressure; The second layer shields, and it is unobstructed to satisfy draining; The 3rd layer is that kinetic head, the protection grogs that reduces to hold the sand current under the arm do not run off.For single piping, can directly rescue and protect below 10 centimetres in its piping aperture; When the piping diameter greater than 10 centimetres or piping group time, also can win the quality time.Like this earth and rock works in the work of combatting a flood is changed into and use the industrial products of producing in batches.It is easy to carry, use is rapid.Can use repeatedly, can reduce the cost of work of combatting a flood significantly.Can accomplish different size, adapt to the needs on different soil properties stratum.Convenience is provided also for transportation, deposit flood fighting material.
