Description

A kind of river closure device for fighting flood and preventing burst

Technical field:

The utility model relates to and the streams, the river course, the control in seashore or other marine sites with utilize relevant engineering, specifically relate to the burst cut-off equipment of (crevasse) of a kind of river or reservoir dam.

Background technology:

The topmost method of flood fighting choked flow is still and utilizes manpower at present, gathers materials on the spot, and is stacked among the current with fiber (cloth) bag of filling sandy soil.The method is simple, and reaction speed is fast, but field conduct danger is high, obstruction efficient is low.In order to resist this serious natural calamity, people develop the various resistances cut-off equipment of determining, State Intellectual Property Office disclosed a kind of " burst-blocking equipment " on November 30th, 2002, and (publication number is: 1380468A) application for a patent for invention, should " burst-blocking equipment " connect to form by supporter, net and stay cord, shape such as umbrella, use the anchor tractive at the downside that bursts, throwing filler in bursting again, utilize described " burst-blocking equipment " thus interception firmly filler reach the purpose that resistance is certainly dammed.Should " burst-blocking equipment " can only play the effect of tackling block filler obviously, still need a large amount of fillers.State Intellectual Property Office's mandate on December 4th, 2002 discloses a kind of " emergency flood-control screen for combatting flood ", and (notification number is: 1095515C) patent of invention, this patent is to cover the rubber leather or the plastics leather forms having on the metal net shaped body of metal edge frame, and the pressure that utilizes current dexterously overlays rubber leather or plastics leather and form a screen that dams on metal net shaped body.Compare the art of this patent with last patent application and have the outstanding advantage of saving mass filler, but remain in following deficiency: 1, since current breathe heavily and anxious formed " screen " produced huge pressure, therefore need be under metal net shaped body (trip) side beat a row or several rows and could prop up and be strong enough to support; 2, since current to breathe heavily the anxious operation that covers rubber leather or plastics leather on metal net shaped body very difficult, in case the shop partially just is difficult to correct.

Summary of the invention:

The utility model purpose provides a kind of river closure device for fighting flood and preventing burst easy and simple to handle, and this device both need not filler, also need not beat a large amount of supporting piles.

The utility model realizes that the technical solution of above-mentioned purpose is:

A kind of river closure device for fighting flood and preventing burst, it is characterized in that one is lying in that suspention has row's vertical rod on the crossbeam of breach upper support, this vertical rod upstream diagonally extending is to be connected to water bag between vertical rod to water-bed earth, the top of water bag bottom is provided with pore, is provided with the ball float of a diameter greater than hole diameter in the water bag.

The upper end that a preferred embodiment of technique scheme is described vertical rod is provided with suspension ring, and crossbeam is through in these suspension ring.

Another more excellent embodiment of the present utility model is that described water bag mouth is provided with rigid support ring, and it is to be connected between two vertical rods that every water bag intersects, and vertical rod is uniformly distributed on the crossbeam.

A more excellent scheme of the present utility model is that described rigid support ring is provided with is to connect aperture.

The utlity model has following significant technique effect:

1, be full of water in the water bag after, ball float will be blocked pore, mighty torrent closely presses together the water bag rising mutually, forms a water curtain and reaches the purpose of damming, and need not the filler of jettisoninging, water-control is skillfully constructed;

2, vertical rod is upstream tilted, and produce vertically downward a component on crossbeam, and the fast more component vertically downward that produces of current is big more, and promptly the pressure that produces at the supporter of bearing cross beam is just big more, need not to beat intensive supporting pile.

3, each parts all is independently, and volume is little, and accumulating is convenient.

Description of drawings:

Fig. 1 is the structural representation of a specific embodiment of river closure device for fighting flood and preventing burst described in the utility model;

Fig. 2 is the structural representation of water bag among Fig. 1;

Fig. 3 is a kind of user mode figure (overlooking) of enforcement illustrated in figures 1 and 2;

Fig. 4 is the another kind of user mode figure of enforcement illustrated in figures 1 and 2.

The specific embodiment:

Select the steel pipe of 250 millimeters of Φ for use referring to Fig. 1 crossbeam 1; 60 millimeters steel pipe manufacturing bodies of rod of Φ are used in vertical rod 2, and the upper end suspension ring use the round steel of 20 millimeters of Φ to bend, and its endoporus is 260 millimeters of Φ.

Referring to Fig. 2, water bag 3 end user's fabricate-leather or canvas are made.Sack is provided with the rigid support ring 4 of flange-like, and anchor ring is provided with is convenient to the aperture 5 that wire rope handling system connects; The top of water bag 3 bottoms is provided with pore 6, is provided with a ball float 7 in the bag, floats on the water water-in-bag 8, and the slightly larger in diameter of this ball float 7 is in the diameter of pore 6.

Referring to Fig. 3, when breach is narrower, can use a steel pipe to make crossbeam 1, cover upper pright stanchion 2 (radical can calculate according to the diameter of width that bursts and rigid support ring 4) back cross-arm is on the dykes and dams 9 of breach both sides, make the lower end of vertical rod 2 extend to water-bed earth 10 simultaneously to the upstream oblique of bursting, its angle of inclination can be selected in 20～45 degree according to the speed of mighty torrent 11, the fast choosing of the speed of mighty torrent 11 is selected point more slowly; Then water bag 3 usefulness ropes are intersected and lie between two vertical rods 2, its density can be adjacent to mutually during with the water bag rising and be advisable.Water bag 3 risings under the effect of mighty torrent 11 form a water curtain breach are blocked.

Referring to Fig. 4, when the breach broad, can use a bracing frame 12 according to the lap-joint that the width that bursts uses several steel pipes to contact to make 1, two crossbeam 1 of crossbeam, this bracing frame 12 is connected and composed by two piles and a cross-arm.
