2. multi-functional: as can be combined into not isomorphism type according to different needs, to finish multi-functional demand.

3. sedimentation is fast: low as the sinker center of gravity, and not slippage, stability is high, is difficult for running off

4. effective: as topped thing, it is good that opposing water wave bounces scouring effect.

5. reduced investment can put recovery in order, reuse after the end of speedily carrying out rescue work, and the silt of filling is handled on the spot, saves flood fighting expense input.

6. easy to use: assemble rapidly the job site, and desirable everywhere earth or sandstone are filled.Formation is than great and firm sinker.Must be with the trouble of many cars, a large amount of stones of ship deposit when having overcome flood control, be particularly suitable for the earth embankment urgent need of speedily carrying out rescue work.

Accompanying drawing 10,11 is arranged wave absorption or fill dash schematic diagram for the Foldable multifunctional case.

Accompanying drawing the 1, the 2nd, embodiments of the invention, drawing is described as follows: 1. triangle iron plate 2. hoisting rings 3. detachable hinges 4. fixed hinge 5. jacket type connectors 6. pin holes.

Now 1 to 11 be described below in conjunction with the accompanying drawings: as shown in Figure 1, make the positive corner block 1 of assembly of elements with steel plate.Be decided to be several models according to length of side length, arrange the hinge number by model.Fig. 2 provides full split-type folding carton unit corner block structure chart, is combined into folding carton by four crimping triangles and six jacket type connectors 5.According to Fig. 3 and two kinds of various combinations of Fig. 4 four corner block unit are connected into the Foldable multifunctional case with fixed hinge 4.Its periphery welding band latch split-type hinge 3, or button and other type connector also can as connecting with bolt.Be connected in flakes with Fig. 6 mode by Fig. 5 according to the combination block shape during tiling bank protection, along tiling of slight slope inclined-plane and expansion to the left and right.Be fixed in drill rod insertion pin hole and prevent downslide in the dike on the slope, the dike face can be kept out washing away of billow under the protective effect of this laying.

Assemble by Fig. 7 when making sinker and using, fix three earlier during the flood control construction, charge into the 4th locking of closing again behind the silt, see Fig. 8.Also available four same model triangles combination pieces (16 blade unit parts are arranged) are combined into the positive tetrahedron of the big octuple of volume, are used to dam the Yangtze River determine with flood fighting is stifled.The method of combination large size sinker is undertaken by Fig. 9.Closely being arranged on the levee slope wave absorption wave, antiscour with the Foldable multifunctional case implements by Figure 10.The dike face is promptly increased the fill dash and can be implemented by Figure 11.

Details are as follows to erection scheme of the present invention and job practices particularly:

1. combination block tiling bank protection: on embankment, construct during the flood fighting flood prevention or control, several piece interlocks in flakes, form whole topped on levee slope, because all triangular elements are to connect with hinge, can regulate being attached on the ground with the levee slope face that convex-concave rises and falls naturally, iron triangle piece nail is fixing on the dike face with drill rod again by pin hole, so can play admirably and resist bouncing and washing away of water wave, prevent that sandy soil from staying loss, reach the purpose that shore protection is protected dike.

2. sinker is stifled determines: with the loose-leaf hinge four equilateral triangle steel plates with size are linked together, form positive tetrahedron, the four sides intracorporeal space can use mud, sand, soil to fill, and forms than the efficient sinker great, that resistance is little; If with four groups totally ten six blocks of these equilateral triangle steel plates link together positive tetrahedron sinker that will the composition above-mentioned sinker of volume ratio big octuple.This shape sprue resistance in water is little, subsidence velocity is fast; Center of gravity is low, antiskid is moving; Be difficult for being washed away by mighty torrent.The corner block of making different size also adopts the sinker of two kinds of different volumes combinations to be used when flood control, just can adapt to stifled the determining or dam different needs when closing ridge of hydraulic engineering of speedily carrying out rescue work.

3. the stifled eye of sinker during piping: positive tetrahedron can use when piping takes place as sinker, its shape rigidity is not yielding, corner angle are in anchor may be stuck in the piping passage, the sandstone that its wedge structure can push peripheral soil and drop into are simultaneously subdued piping rapidly.

4: sinker system seepage during depression: when the dike face occurred subsiding with seepage, available positive tetrahedron point angle pressed downward to subside place and leakage, the top intensified pressure, and it stops up and squeezing action makes loose soil compaction, thereby stops to live the embankment seepage.

5. the sinker wave that disappears protects ripple during flood peak: tile with sinker in important dike section, the awl point is upwards closely arranged in flakes.Because this sinker center of gravity is low, stability is high, and the attenuating of the flow velocity of flood and the dissipation utmost point of wave pressure kinetic energy are had effect.Guarantor's base of earth embankment is protected the ripple utmost point to produce effect.

6. fill dash: use the folded piece marshalling during emergency, and folded piece is linked to each other by pin hole with iron wire, be aided with the earth antiseepage, can form firm interim dykes and dams, need promptly to increase Shi Gengxian convenient for certain dike section in flood control.
