The purpose of this utility model also can realize by following measure: above-mentioned reinforced concrete frame interlocking piece by the steel concrete anchoring pile be fixed on domaticly go up, the steel concrete anchoring pile with reinforced concrete frame constitute compound beam with fixing under water compound soft raft and concrete mould bag and precast concrete lock dog under also be provided with weeper drain and geotextiles bed course; Above-mentioned compound soft raft length direction Transverse to the flow direction, the width Parallel to the flow direction; Above-mentioned compound soft raft is sewn into by the high-strength woven cloth of long filament: charged the concrete hard layer in its top concrete mould bag, charged the combined overall structure of sand soft layer in the sash type mould sack for filling sand of bottom; Above-mentioned sash type mould sack for filling sand is sewn into some cell cubes, be provided with some suturing parts in each cell cube, its suturing part periphery charges sand formation and has the sash shape of main rib and auxilliary rib, cut off by the two-sided reinforced bands that is stitched together mutually between above-mentioned each cell cube, a side of its each cell cube is provided with and fills Sha Guankou; Above-mentioned main rib fills the diameter after the auxilliary rib of the big what of diameter behind the sand fills sand.

The utility model has the advantages that: compound soft raft and reinforced concrete frame interlocking piece have constituted the integral framework of administering collapse on the bank, compound soft raft is made by the high-strength woven cloth of long filament and is formed, can directly provide from factory, but so accelerating construction progress, improve work efficiency, fixing superiority such as riverbank, poised river gesture, reduction flow velocity, anti-impact wave resistance, have wide development and application prospect, collapse the road that a success is developed in the improvement of collapsing with bar for administering collapse on the bank, particularly whirlpool.

Now further specify by the following drawings and embodiment:

Fig. 1, be plane structure chart of the present utility model.

Fig. 2, be construction profile of the present utility model.

Fig. 3, be sash type mould sack for filling sand structural representation.

Fig. 4, be the cell cube structural representation among Fig. 3.

Fig. 5, be the A-A sectional view among Fig. 4.

Referring to Fig. 1-2, a kind of compound row's body of administering collapse on the bank, comprise that mainly reinforced concrete frame interlocking piece 1 and compound soft raft 2 constitutes, wherein, reinforced concrete frame 12 and embedding precast concrete lock dog 11 within it be connected to form one be positioned at domatic on; Above-mentioned compound soft raft 2 is made up of concrete mould bag 21 and sash type mould sack for filling sand 22 two parts, concrete mould bag 21 with its under sash type mould sack for filling sand 22 by grappling hook 4 be connected place domatic down, sandbag presser feet 3 then places the bottom of sash type mould sack for filling sand 22, to avoid the mould bag washed away.

Above-mentioned reinforced concrete frame 12 by steel concrete anchoring pile 6 be fixed on domaticly go up, steel concrete anchoring pile 6 constitutes compound beam with fixing compound soft raft 22 under water with reinforced concrete frame 12, and prefabricated interlocking piece also is provided with weeper drain 7 and geotextiles bed course 8 for 11 times, sometimes need in the engineering on domatic, to stack sand filling pipe bag 5 pad slopes, make slope leveling, above-mentioned compound soft raft 2 length direction Transverse to the flow direction (as Fig. 1 direction of arrow indication), the width Parallel to the flow direction.

Referring to Fig. 3-5, above-mentioned compound soft raft 2 is sewn into by the high-strength woven cloth of long filament: charged concrete in its top concrete mould bag 21, become hard layer, charged sand in the bottom sash type mould sack for filling sand 22, become an overall structure of soft layer, on sash type mould sack for filling sand 22, be sewn into some cell cubes 221, be provided with some suturing parts 222 in each cell cube 221, its suturing part 222 peripheries charge sand formation and have the sash shape of main rib 223 and auxilliary rib 224, see it is one and another bulge from integral body, cut off by the two-sided reinforced bands that is stitched together mutually between each cell cube 221, can be divided into vertical insulating course 23 and horizontal insulating course 24, be used to transmit pulling force, select for use the tensile strength of reinforced bands must be high,, be provided with at a side of each cell cube 221 in addition and fill Sha Guankou 9 to adapt to the demand of engineering; And main rib 223 fills the diameter after the auxilliary rib 224 of the big what of diameter behind the sand fills sand.
