The keel 4 are processed by shaped steel, by Screw arbor with nut at both-ends device drawknot in the panel away from concrete retaining wall Skeleton side prevents panel skeleton 2 from deforming to bearing plane framework load.
The Anti-floating reinforcing steel bar 11 is the reinforcing bar for being embedded in basis and stretching out basis, and Anti-floating reinforcing steel bar 11 is arranged away from coagulation The panel skeleton side of native retaining wall, Anti-floating reinforcing steel bar 11 is welded on panel skeleton 2 or steel facing 1, casting concrete is prevented When large steel moulding plate structure floating or sliding.
A kind of installation method of the anti-anti-floating large steel moulding plate device that inclines of cast-in-place concrete retaining wall comprising following steps:
S1, processing steel facing, panel skeleton, lifting lug, keel, Screw arbor with nut at both-ends device, wirerope, anchorage, bolt, anti-floating steel Muscle;
S2, welding steel facing and panel skeleton form steel form, and lifting lug is welded on steel facing;
S3, installation steel form, are connected by screw bolts composition large steel moulding plate structure at the rib of adjacent panels skeleton side;
Wirerope between S4, installation lifting lug and anchorage adjusts large steel moulding plate structural point by wirerope, and welding Anti-floating reinforcing steel bar is in steel On panel or panel skeleton;
S5, installation keel and Screw arbor with nut at both-ends device, the screw rod inside casting concrete need to be arranged PVC when mounted Pipe, prevents Screw arbor with nut at both-ends from linking into an integrated entity with concrete;It is pre- in steel facing after installation is complete Screw arbor with nut at both-ends device for mortar leakage prevention It stays and does encapsulation process at split bolt hole.
S6, the casting concrete between two large steel moulding plate structures.
The utility model has the characteristics that and advantageous effect compared with prior art:
The utility model pours inclined gravity formula concrete retaining wall using the anti-anti-floating large steel moulding plate device that inclines, and solves biography System tilts the problem of being easy to topple, float or slide in large steel moulding plate work progress, has operating procedure few, and concrete formation is beautiful The characteristics of sight, reduces construction cost to reduce working hour.
