Description

Truss for blocking break of a dike

The application's genus is divided an application original application day: 980819, and application number: 98231212.1, invention and created name: Plugging iron cage and Truss for blocking break of a dike.

The present invention relates to a kind of Truss for blocking break of a dike 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 Truss for blocking break of a dike, 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: one side Truss for blocking break of a dike is that making up-narrow and down-wide one by one by shaped steel is trapezoidal truss, its bottom can be provided with spike-tooth, and the both sides of Truss for blocking break of a dike are provided with the hole, can a plurality ofly link together, and form a big composite roof truss.Each can weigh several tons to tens tons, and one time the water blockoff area can reach tens up to a hundred square metres.In the inside of Truss for blocking break of a dike, be provided with buoyant device (as hull, floating drum, air bag etc.) it can be floated in the water, be convenient to transportation and input.Buoyant device can or destroy in the moment unlatching, makes the Truss for blocking break of a dike loss of buoyance and sinking rapidly, when the flood breach takes place, the Truss for blocking break of a dike traction to the scene, is sent into the appropriate location of breach, opens or the destruction buoyant device, and Truss for blocking break of a dike is sunk rapidly.Because the ratio of Truss for blocking break of a dike is great, resistance is little, thus can be not washed away, water speed is increased.After Truss for blocking break of a dike sets, set up Plugging iron cage in its both sides again, breach is advanced to the centre from two, set up the water blockoff wall, join the two sections of a bridge, etc at the Truss for blocking break of a dike place again.One side that Truss for blocking break of a dike meets water is provided with fence and is convenient to set up the water blockoff wall.Also can establish gate, gate is opened before closure, to reduce the resistance of Truss for blocking break of a dike after transportation and sinking, when closure, as long as close upper lock gate.This structure is suitable for blocking fast big breach, can a plurality ofly unite use.Also be suitable for setting up defence line, two roads.Truss for blocking break of a dike 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 hydrotransport and sinking, its feature is the framework of setting up the water blockoff dam and sets 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, make action of gravity that the pressure of flood potential difference becomes dam body on the dam foundation, thereby dam body and basis are combined.

According to the above, Truss for blocking break of a dike has solved the technical barrier that the flood breach is blocked up, and can set up the framework that the water blockoff wall is set up in a support at breach quickly and effectively, mixes other facility again, 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.

Be further described inventing again in conjunction with the accompanying drawings down and again:
