Abstract

The invention discloses a piping expansive bag. The outline of technology project is that the piping expansive bag comprises waterproof plastic bag, outer-layer bag, inner-layer bag, guiding rope, dragging rope and water absorption expansive agent; the water absorption expansive agent is set in the inner-layer bag and the water absorption agent comprises attapulgite clay, bentonite, anhydrous plaster powder and high water-absorbing resin. When it is used the waterproof plastic bag is torn, floodwater enters into the inner-layer bag through the outer-layer bag of piping expansive bag. After the water absorption expansive agent in inner-layer bag meets water, the weight and the cubage increase more than 50 times gradually based on the original bag. Flat piping expansive bag becomes a cylinder piping expansive bag with cone-shape front end to jam leak or piping quickly. The piping expansive bag is suitable for jamming leak or piping in flood resisting, building construction.

Description

Piping expanding bag

Technical field:

The leak stopping new material that the present invention relates to control flood is specifically related to a kind of piping expanding bag.

Background technology:

Under flood season high water level situation, the hole appears near the seepage flow hole that traverses levee body downstream slope or the backwater toe, is called leak; Sand soil is constantly taken away by current under the seepage force effect, and the phenomenon of shape tubulose seepage channel is piping, and piping generally occurs near ground of backwater toe or Tan Keng, pond or depression far away, is the poroid water that emits more and emits sand.The delivery port aperture little as the ant cave, big reaches tens centimetres.Number at least one or two, dozens of is called the piping group at most.Leak and piping dangerous situation must in time be rescued and protected, and dangerous situation should be eliminated in bud, and as not rescuing and protecting, this trend continues, just will empty the sand bed under the ground, causes dyke to subside suddenly, causes the dyke crevasse.

In a single day leak or piping take place in embankment, use nonwoven, cotton-wadded quilt, cotton-wool, straw bag, gunnysack, woven bag bag, net bag, cotton dress, grass handle, earth or sandstone effectively not to control the dangerous circumstances merely.

Summary of the invention:

The objective of the invention is to overcome weak point in the prior art, a kind of easy to use, accurate positioning, the fast piping expanding bag of speed of expansion are provided.

Piping expanding bag is made up of waterproof plastic bag, outer bag, inner layer bag, guide cords, drag rope and water absoption expanding agent, water absoption expanding agent is housed in the inner layer bag, and water absoption expanding agent is made up of Concave-convex clay rod, swell soil, anhydrous plaster powder and high hydroscopic resin.

The present invention is achieved by following technical proposals:

1, piping expanding bag is made up of waterproof plastic bag, outer bag, inner layer bag, guide cords, drag rope and water absoption expanding agent.

2, the waterproof plastic bag adopts plastic sheeting to make, the length of waterproof plastic bag is 22～210 millimeters, wide is 5～110 millimeters, outer bag adopts gunnysack or Polywoven Bag to make, and the length of outer bag is 20～200 millimeters, and wide is 5～100 millimeters, inner layer bag adopts chemical fibre cloth bag or non-woven bag to make, the length of inner layer bag is 20～210 millimeters, and wide is 5～110 millimeters, and the water absoption expanding agent of 0.1～15Kg is housed in inner layer bag.

3, the front end of outer bag and inner layer bag all is made into taper, and the length of outer bag taper is 5～25% of outer bag total length, and the length of inner layer bag taper is 6～28% of inner layer bag total length.

4, in the upper end of outer bag taper, make 1 guide cords, the length of guide cords is used for the object of bolt button guiding greater than 20 millimeters, piping expanding bag is sent into the hole of leak or piping; 1 drag rope is made in the outer bag lower end, and the length of drag rope is greater than 30 millimeters, is used for operator's traction and fixing piping expanding bag.

Water absoption expanding agent is made up of Concave-convex clay rod, swell soil, anhydrous plaster powder and high hydroscopic resin.Water absoption expanding agent and production method thereof are to be filed an application on October 27th, 2004 by the inventor, and on February 28th, 2007 granted patent, and license number is ZL200410065139.0.

The using method of piping expanding bag: the position that will determine leak or piping hole earlier, utilize the UDeflector on the piping expanding bag guide cords, piping expanding bag is sent into the hole of leak or piping, tear the waterproof plastic bag, flood enters inner layer bag by the outer bag of piping expanding bag, after water absoption expanding agent in the inner layer bag runs into water, on the basis of former marsupial bag, its weight and volume increases expansion more than 50 times gradually, flat piping expanding bag forms the cylinder piping expanding bag that front end is tapered, utilize the bullet of piping expanding bag front end, can guide piping expanding bag to enter the inside of leak or piping exactly, the piping expanding bag after the expansion stops up leak or piping live rapidly.

Because the interaction of Concave-convex clay rod, swell soil, hard burnt plaster and high hydroscopic resin, the water absoption expanding agent in the bag is evenly distributed and is closely knit, and Concave-convex clay rod, swell soil and hard burnt plaster also play the skeleton function that supports high hydroscopic resin.

After flood control or construction finished, piping expanding bag was not owing to there is the immersion of water, and atrophy gradually helps removing piping expanding bag, and to starting a leak or repair the position of piping, piping expanding bag also can repeat repeatedly to use after drying.

Piping expanding bag is applicable to that flood fighting water drainage is speedily carried out rescue work, stop up a loophole or piping in water conservancy and the building operations.

Description of drawings:

Fig. 1 is the schematic diagram of piping expanding bag.

As shown in the figure: the 1st, guide cords, the 2nd, inner layer bag cone, the 3rd, outer bag cone, the 4th, outer bag, the 5th, inner layer bag, the 6th, waterproof plastic bag, the 7th, water absoption expanding agent, the 8th, drag rope.

The specific embodiment:

The invention will be further described below in conjunction with embodiment:

2, the waterproof plastic bag adopts plastic sheeting to make, the length of waterproof plastic bag is 62 millimeters, wide is 18 millimeters, outer bag adopts gunnysack or Polywoven Bag to make, and the length of outer bag is 60 millimeters, and wide is 16 millimeters, inner layer bag adopts chemical fibre cloth bag or non-woven bag to make, the length of inner layer bag is 62 millimeters, and wide is 18 millimeters, and the water absoption expanding agent of 2Kg is housed in inner layer bag.
