Description

Plugging iron cage

The present invention relates to a kind of Plugging iron cage of making by shaped steel, be adapted to set up when flood bursts the dam of blocking up especially.

At present, when flood damage takes place, adopt ways such as piling, parabolic, shipwreck to block up.By " the steel, wood, soil and stone mixed dam " of the invention of Beijing army, be to adopt pricking several rows of steel pipe frame on the basis of breach recently, be thrown into a large amount of sandy gravel bags and piece stone again, this technology only is adapted to 7 meters of the depth of waters, the current operation of flow velocity 1.5 metre per second (m/s)s.When adopting the piling method, because can only adopt manually, work efficiency is extremely low, and labour intensity is high, also can not beat very deeply, and must beat on levee foundation, and the intensity of levee foundation is had destruction.Too soft or too hard as basic soil property, stake just is difficult to beat steady, and construction is difficulty quite, and when breach had occurred and enlarging, piling was just quite dangerous.When adopting the shipwreck method, because of the proportion of ship is lighter than water, is difficult to control and sinks, the shipwreck position is difficult to accurately, and when closure, might produce impact force the water blockoff wall that has formed is uprooped, or the dykes and dams avalanche that does not collapse.Moreover this method does not fit into big breach.Adopt methods such as Rhizoma Smilacis Chinensis, iron cage mounted stone, because after Rhizoma Smilacis Chinensis or iron cage mounted go into stone, the proportion sharp fall, resistance increases suddenly, so though they weigh nearly 10 tons, still can be swept away by the torrent.The breach big for drop, that current are anxious also is " getting half the result with twice the effort ", and the area of blocking up that said method once forms is all quite limited, and manpower, amount of materials consumed are surprising.Occurring in Anxiang, Hunan peace in 1998 seven-August makes the breach of protective embankment and blocks up, all existing ways have been adopted, last 16 days, just join the two sections of a bridge, etc in the time of at last also can only drop is reduced to 1.61 meters by more than 10 meters inside and outside breach, long especially if not peak water level duration then, the meaning of blocking up specifically is little.

According to the above, also there is not a kind of equipment of blocking up of special use at present, can not be subjected to the restriction of geological conditions, and block breach rapidly with minimum manpower, material consumption as far as possible.

The purpose of this invention is to provide a kind of Plugging iron cage, it is not subjected to the restriction of breach geological conditions, and the breach that can promptly stem the flood and inrush can reach minimum manpower and material consumption again.

The object of the present invention is achieved like this: Plugging iron cage is the elongated cylindrical iron cage by section steel manufacture, it is linked together with many long purlins by a plurality of outer rings, the outer ring outside, its center is welded with cross to increase its radially bearing capacity, between outer ring and the diagonal angle, outer ring, be welded with many groups and be the diagonal brace that a plurality of directions are provided with, to increase the axial and angle supporting capacity of iron cage.The end that Plugging iron cage meets water is welded with the reinforcing bar fence, is convenient to set up the water blockoff wall, in order to increase Plugging iron cage and basic binding ability, is welded with many row's spike-tooths around the part Plugging iron cage, and this Plugging iron cage is arranged at lower floor.Laterally being easy to of Plugging iron cage rolled, and is convenient to carrying and is provided with.When a plurality of Plugging iron cages are stacked,, can not axially promote wherein any one because its outer ring and cylindrical block mutually.Its diameter can reach more than one meter, the water blockoff area of each can reach more than 1 square metre, length can reach the several times of diameter, weight hundreds of kilogram is to several tons, because resistance is little during its entry, proportion is 7.8 times of water, can be not washed away in the breach so push, also not too influence the flow velocity of water, need not any reinforcement measure just can form a stable framework, set up the water blockoff wall then or synchronously.The water blockoff wall can be used sand pocket, steel plate or other equipment special.Because this moment, breach formed a stable framework, the ship of delivery goods and materials can have been accelerated the process of blocking up near the breach operation.After Plugging iron cage pushes in the breach, embed in the earth on basis, can bear very big thrust because of the spike-tooth around it always has one side.After the water blockoff wall was set up, Plugging iron cage was not influenced by buoyancy of water, and the hydraulic pressure outside the dike has increased the weight of dam body like this to the angled dam foundation (the arrow A place among Fig. 5) of pressing in the whole dam of blocking up with regard to the pressure that has utilized water-head.Even the earth that the basis is soft, the Plugging iron cage of lower floor (can adopt the anti-iron cage that falls into) is absorbed in the earth, or base integral sinks, and still can form the firm dam of blocking up, soft earth, and effect is remarkable.When the breach drop is too high, can establish many row's Plugging iron cages in lower floor, and they vertically are chained together, its length can reach more than 30 meters, like this, even breach is up-and-down physical features, still can play a role effectively.After the water blockoff wall was set up, the iron cage was in the backwater end, is exposed to fully in the air, and the water blockoff wall can be found rapidly and be handled if any leakage.

Plugging iron cage is a kind of emergency flood fighting of special use equipment of blocking up, can make standby in advance, in case flood takes place to burst, can be transported to the scene rapidly, they can be manually, hydrotransport and sinking, also can adopt helicopter to hang, their characteristics are the framework of setting up the water blockoff dam and set up the water blockoff wall and proceed in two phases, both avoided buoyancy of water and impact force to setting up the destruction of water blockoff wall, the pressure of water-head increases the weight of the weight of dam body inside and outside utilizing again, the action of gravity that makes dam body on the dam foundation, thereby dam body and basis are combined.

According to the above, Plugging iron cage has solved the technical barrier that the flood breach is blocked up, and can set up a support at breach quickly and effectively and set up the framework of water blockoff wall, as mix other facility, can prevent the expansion of breach rapidly, and then set up or set up synchronously the water blockoff wall; Highly difficult engineering when it does not have closure, the goods and materials that can guarantee to block up are absolutely not washed away.It can make standby in advance, can be transported to the scene rapidly, can adopt artificial, waterpower sinking or helicopter to hang, consume human and material resources and have only below 1/10th of existing method; It is not subjected to the restriction of breach basic geology condition, the soft place of soil property, and effect is remarkable, even base integral sinks, also its stability of entail dangers to not.It is through after the antirust processing, can long-term storage, and repeated multiple times is used, and its life-span can reach more than 100 years, and use cost is quite cheap, and is convenient to cleaning after using, and has reduced the difficulty and the cost that recover the damaged or destroyed by flood engineering.
