Preformed hole be fixedly connected, it is arranged side by side on same side through there is pull bar between the bracket on forward and backward side
Tray support is set between bracket, and the upper end on the inside of PHC pile tubes is laid with damper, is set respectively between adjacent PHC pile tubes
Hound, supported rod erecting and support rail are put, the supported rod erecting is disposed longitudinally on the lower end of Bailey beam, adjacent supported rod erecting
Bottom be fixed with support rail, one end of hound is fixed in Bailey beam, and the other end is fixed on the side of supported rod erecting bottom
On wall, the bottom of hound sets connecting seat, and connecting seat and damper are attached.
Further, transverse distribution beam is fixed between the sandbox and Bailey beam.
Further, the tray support includes four transverse reinforced bars and two middle studdles, four horizontal strokes
It is in " mouth " font to bracing piece combination, two middle studdles are in " X " font, and middle studdle is located at the interior of transverse reinforced bar
Portion.
Further, the damper is viscous damper.
Further, the hound, supported rod erecting, pull bar and support rail are screw-thread steel.
The utility model is a kind of Cast-in-situ Beam falsework for soft base matter, and its advantage is：
The utility model adds the PHC pile tube falseworks of Bailey beam plus total sub-semigroup, whole falsework body using PHC pile tubes
Architecture stabilization, safe and reliable, applicability is good, and PHC pile tubes cooperate with Bailey beam and total sub-semigroup, while increasing
Bracket, it is easy construction, simple to operate, the revolving of girder steel is improve, to surrounding environment without in larger interference, and construction in construction
Do not limited by spanning headroom, increased hound, supported rod erecting and support rail in the bottom of Bailey beam, under can effectively increasing
The intensity of string bear external force, it is possible to reduce truss quantity and amount of deflection, makes Bailey beam uniform force, and damper can effectively increase
The durability of bridge.
