Description
Technical field
The present invention relates to flood control works technical fields, in particular to the method and device of blocking up after a kind of dyke breaking.
Technical background
Dyke building is to resist a kind of flood measure, therefore it is widely deployed and prevents in water conservancy
In big vast engineering.But by economic condition, influence the problems such as historical reasons, China's existing dike there are levee body conditions poor, levee body
A variety of hidden danger such as material and construction quality difference.When dyke is by the attack of flood, flood is more than the resilience or Gao Shui of dyke
Position flood, which impregnates dyke for a long time and occurs rescuing and protecting, improper can all cause to burst.
Due to various reasons, it is very difficult to eliminate dyke breaking phenomenon, the existing tradition in China technology of blocking up mainly has
Native stone is blocked up, gabion is blocked up, the method for attacking and occupying of driving piles is blocked up, shipwreck is blocked up and the special bags of willow branches, framed by bamboo, for building dykes work method of attacking and occupying is blocked up, but by breach at
The conditions limitation such as the depth of water, flow velocity, drop, soil property.These technology enforcement difficulties are big, have a lot of preparation work, construction efficiency is low, operation
Personnel hazard's coefficient is high, expends a large amount of manpower and material resources, and time-consuming for construction, causes submergence ratio big, people's life and wealth
It is big to produce loss.
Summary of the invention

It holds and is fixed on the dike head of breach both ends；The truss is connected on hawser, for jettisoninging into breach together with hawser
Form basic water blocking skeleton, it is preferable that truss is made of steel pipe or reinforcing bar；
C jettisonings on the dike head at breach both ends anchor and fixation respectively, so that the hawser being connected on two anchors is taut
Tightly and it is across breach top；
Truss is fixed on hawser and jettisonings into breach by d；
E first jettisonings vegetation beam toward truss upstream side, then throwing earth and stone material completes work of blocking up until fill up breachs.
Preferably, distance of the anchor away from dike head is 1~10m.
Further, anchor is fixed in the step c to refer specifically to that anchor is first fixed on dike head, then is increased at anchor position
If steel-pipe pile, and fill block stone throwing ballast.Increase the stability of entire water blocking process.
Still further, the truss is disposed with 2~5 rows along breach direction, increase the stability of entire water blocking skeleton.
A kind of plugging device after dyke breaking, is characterized in that including anchor, hawser and truss, the purlin
The connecting rope with hook is provided on frame, the anchor is for holding hawser both ends and being fixed on breach both ends dike head；Institute
It states truss to be connected on hawser by hook, the purlin is formed together basic water blocking bone with hawser for jettisoninging into breach
Frame.
Further, the truss includes the multiple circular frameworks of the center of circle on the same line, and the circular framework is by even
Extension bar is fixed, and is provided with more interception bars on the circular framework, and the interception bar and circular framework are in the same plane and edge
Even circumferential arrangement, each interception bar meet at the center point, and end is circumferentially outer to be distributed in divergent shape, intercept bar and intersect at
The center of circle and the center point is fixed on the methods of welding or riveting.This truss is conducive to keep stable in water, and in breach
Play the role of supporting and retaining system.
Further, the truss is provided with two kinds of sizes of size, and the small size truss is located at the side that meets water, described big
Size truss small size truss downstream.The setting structure makes truss form more closely knit retaining structure in breach, favorably
In supporting and retaining system vegetation beam and earth and stone material.
Preferably, the circular framework is provided with 2~10.
Still further, the circular framework spacing is 0.6~1m.
Still further, the circular framework is fixed by 2~6 connecting rods, large-sized truss intercept bar it is long by 3~
