Two veneer anchor shins connect one to one with two symmetrical anchor slabs, wherein each veneer anchor shin is by more respectively A veneer anchor chain composition, one end of multiple veneer anchor chains are connected with first angle adjuster, multiple veneer anchor chains The other end be connected with the anchor shin connecting hole of one of them symmetrical anchor slab；The first peace is connected on the first angle adjuster Wiring；

Double plate anchor shins are made of multiple double plate anchor chains, one end of multiple double plate anchor chains and second angle adjuster phase Connection, the other end are connected with the outer side anchor shin connecting hole of two symmetrical anchor slabs respectively；Wherein, the second angle tune The second hookup wire and anchor are connected on section device；

When being in Installation Modes, the anchor body is in merging phase and is fastened in the bottom groove of suction caisson, institute The first hookup wire, the second hookup wire and anchor is stated to be located in the suction caisson；When being in operating mode, two symmetrical anchor slabs Rotation is extremely coplanar with the connecting plate, the connection buckle locking.

Further, each symmetrical anchor slab can be independently 0 ° -90 ° around the angle of connecting plate rotation.

Further, the top of the suction caisson is equipped with fixation hole, described when being in Installation Modes, first peace Wiring, the second hookup wire and anchor are fixed in the suction caisson by the fixation hole.

Further, the shape of the symmetrical anchor slab is plate, and the surrounding edge anchor shin of the symmetrical anchor slab connects The quantity for connecing hole is four.

The installation method of installation of the invention double anchor slab suction penetration type normal direction load anchors described above comprising following Step:

S1, by anchor body overturning merge after be fastened in the bottom groove of suction caisson, the first hookup wire, the second hookup wire and Anchor is fixed in suction caisson；

S2, design installation site is reached, suction caisson is withdrawn；

S3, drawing the first hookup wire adjust first angle adjuster, make two symmetrical anchor slabs rotate to the connecting plate It is coplanar, and lock the connection buckle；

S4, the second hookup wire of drawing adjust second angle adjuster, keep anchor body plane vertical with anchor, anchor body enters work State.

Further, it further comprises the steps of: S5, first hookup wire and the second hookup wire is connected into surface buoy.

The beneficial effects of the present invention are: it is combined by using two symmetrical anchor slabs and veneer anchor shin, double plate anchor shins Mode combines the advantage of suction type installation on the basis of high-mechanic normal direction load anchor, solves existing normal direction load anchor and dragging It drags because anchor slab track is invisible in penetration process, and predicts the doubt problem in anchor slab final position caused by hardly possible, meanwhile, this hair Bright have that structure is simple, loaded area is big, and fitting depth is clear, is readily produced and installs, has preferable economy and reliable The advantages that property.
