Abstract
The present invention belongs to the field of flood prevention engineering, and is one emergency burst closing method. The burst closing method includes preparing 4 figure-shaped reinforcing steel bar trusses with empty oil tanks fixed to the bottom; drawing barge and several rows of reinforcing steel bar trusses with tug boat to near the burst; fixing the barge in front of the burst and controlling the drift of the reinforcing steel bar trusses to the burst, breaking the ropes fixing the empty oil tanks to make the trusses sink to the burst; and throwing blocking material from two sides of the burst. The present invention has high burst closing speed.
Description
Technical field
The invention belongs to the emergency flood fighting field of engineering technology, after particularly a kind of river dike crevasse, the method for the shutoff crevasse of speedily carrying out rescue work fast.
Background technology
At present, when the crevasse of burst dyke, standing in the hydroelectric project commonly used blocked up or flat blocking method shutoff crevasse both at home and abroad.Wherein, upright stifled method is on the crevasse both sides, with artificial or machinery plugging material is thrown and be filled to the embankment crevasse, and the material of piling fixed sealing burst-stopping, shutoff crevasse gradually; Flat stifled method is at the embankment dam breach position, encloses several barges, throws toward dam breach position from the barge and fills out plugging material, in case of necessity at the heavy barge of dam breach position, throws toward dam breach position simultaneously and fills out plugging material, Jiujiang embankment crevasse in 1998, the crevasse of having adopted this method shutoff exactly.Above-mentioned two kinds of methods, the former is on narrow and small embankment, carries out every work of shutoff crevasse in the short period of time with high construction intensity, and the material of jettisoninging in embankment crevasse both sides is very dangerous, cause crevasse to continue to cave in probably, the personnel that speedily carry out rescue work are poured torrent; The latter's construction intensity is big, and the transport of materials difficulty of shutoff, cost are also very high.Both all have quite a few plugging material to be washed away by high-velocity flow, form alluvial in embankment, work such as also need finish desilting after flood season, slag tap.
Summary of the invention
Purpose of the present invention is exactly the deficiency at above-mentioned situation, and a kind of employing control device that provides, the 4 font reinforcement frames that will have the interception function accurately sink to the dam breach position of embankment, before the plugging material that throwing is filled out is intercepted at reinforcement frame, and the method for quick blocking crevasse.
The present invention realizes in the following manner: before arriving flood season, the 4 font reinforcement frames that are prepared in advance, and on the bottom reinforcement bars of framework fixed a plurality of empty oil tubes, 4 font reinforcement frames can be floated on the surface.When burst embankment crevasse incident, with tugboat barge and number are arranged 4 font reinforcement frames and be transported near the crevasse.The fixing barge in embankment crevasse dead ahead, the personnel that speedily carry out rescue work control the drift of 4 font reinforcement frames with cable and move to the embankment dam breach position on barge, enable control device then and disconnect fixed empty oil tube rope, remove the buoyancy of 4 font reinforcement frames, make 4 font reinforcement frames dash the heavy crevasse that enters with current.The plugging material of jettisoninging in embankment crevasse both sides then and since the material that is thrown into crevasse by 4 font reinforcement frames effectively interception before reinforcement frame, stopped the plugging material washout, thereby reached the purpose of quick blocking embankment crevasse.
The invention solves the construction plant of speedily carrying out rescue work on embankment crevasse both sides little, throw contradictions such as the easy washout of underfill material, rescue intensity are big, and after can controlling plugging material and sinking to crevasse, tackled by 4 font reinforcement frames, can significantly reduce simultaneously the use amount of shutoff dam breach position material, avoid plugging material by high-velocity flow wash away the excavation, the desilting that form alluvial and increase, later stage engineering quantity such as slag tap.The present invention has improved the speed of shutoff embankment crevasse greatly, for the quality time is won in the crevasse of quick blocking embankment, thereby reduces the economic loss that flood brings.

Fig. 2 is the stereogram of a row 4 font reinforcement frame structures among Fig. 1.
Fig. 3 is the sectional drawing with the present invention one row 4 font reinforcement frame structural traps embankment crevasses.
The specific embodiment
Below in conjunction with Figure of description and embodiment the present invention is further described:
By illustrated in figures 1 and 2,1 for the interception reinforcing bar, is used to tackle the plugging material of jettisoninging.2 is anchor bar, is used to insert dam breach position, plays anchorage effect.3 for the carrying reinforcing bar, is used to carry the plugging material of jettisoninging, and also can play the effect of reinforcing 4 font reinforcement frames simultaneously.4 is bearing bar, is used to support the suffered pressure of interception reinforcing bar.5 for supporting steel bar stress, and 6 is fixed reinforcing bar, with several fixed reinforcing bars, a plurality of 4 font reinforcing bars is welded together at a certain distance, forms a structural frame.By shown in Figure 3,7 expression water (flow) directions, 8 is water surface curve, and 9 is the plugging material of jettisoninging, and 10 is embankment.
4 font reinforcement frames are welded a plurality of 4 font reinforcing bars by several fixed reinforcing bars 6 every 10-200cm, interception reinforcing bar 1 is vertical with support steel bar stress 5 with carrying reinforcing bar 3 with anchor bar 2, interception reinforcing bar 1 is positioned at carrying reinforcing bar 3 and supports the top of steel bar stress 5, anchor bar 2 is positioned at carrying reinforcing bar 3 and supports the below of steel bar stress 5, weld mutually with interception reinforcing bar 1 and support steel bar stress 5 respectively at the two ends of bearing bar 4, between interception reinforcing bar 1 and the interception reinforcing bar 1, between carrying reinforcing bar 3 and the carrying reinforcing bar 3, support between steel bar stress 5 and the support steel bar stress 5 and weld mutually by fixed reinforcing bar 6.
Before flood season, be cemented in a plurality of empty oil drums on the bottom carrying reinforcing bar 3 of 4 font reinforcement frames, 4 font reinforcement frames can be floated on the surface.When burst embankment crevasse incident, with tugboat barge and number are arranged 4 font reinforcement frames and be transported near the crevasse.Fix a barge in embankment 10 crevasse dead aheads, the personnel that speedily carry out rescue work move to the embankment dam breach position with the drift of cable control one row 4 font reinforcement frames on barge, enable control device then, disconnect fixed empty oil tube rope as several different methods such as line traffic control, remote control or ignition, remove its buoyancy, make 4 font reinforcement frames dash to sink and enter crevasse with current, the bearing bar 4 of 4 font reinforcement frames and water (flow) direction 7 relative (as shown in Figure 3), and be anchored at dam breach position.Then in embankment crevasse both sides to carrying reinforcing bar 3 places of the 4 font reinforcement frames plugging material 9 of jettisoninging, also available ZL00230474.0 chain type buoying device web material and ZL 00114576.2 float the stream method of intercepting, on barge, control the 4 font reinforcement frame places that the chain type buoying device web material that is loaded with plugging material drifts to crevasse with cable, before plugging material is discharged into framework, shutoff dam breach position current gradually.Effectively tackled before reinforcement frame by 4 font reinforcement frames owing to be thrown into the material of crevasse, stopped the plugging material washout, thereby reached the purpose of quick blocking embankment crevasse.
