Falsework formula waters of the present invention continuous beam cast-in-place support includes supporting the cushion cap of bridge pier and being positioned at the concrete foundation pile being supported below cushion cap and to cushion cap, cushion cap is fixed with two row's steel-pipe piles, often row's steel-pipe pile is transversely arranged on cushion cap, the steel-pipe pile of its both sides is according to the outward-dipping certain angle of width of continuous beam, middle each steel-pipe pile all erects layout, connect system with spiral steel pipe between steel-pipe pile to be attached, a transverse distribution beam it is fixed with in the upper end often arranging steel-pipe pile, multiple rows of beret truss is longitudinally laid on above each transverse distribution beam, connect with beret truss bracing frame between each row's beret truss, rail is located on beret truss, bowl button is erected at above rail；The model of the cast-in-situ continuous beam being made up of the lumps of wood and template is located at bowl and buckles on support；Being welded with a capital steel plate in the upper end of every steel-pipe pile, be welded with polylith and strengthen steel plate below capital steel plate and between the outer wall of steel-pipe pile, described transverse distribution beam is directly welded on capital steel plate.
Further, on cushion cap, the lower end correspondence position of every steel-pipe pile is embedded with steel plate at the bottom of post, is welded with polylith and strengthens steel plate on steel plate at the bottom of post and between the outer wall of steel-pipe pile.
The building method of falsework formula waters of the present invention continuous beam cast-in-place support, its step is as follows:
The first step, drilling concrete basis stake holes on riverbed, casting concrete foundation pile and cushion cap, when cushion cap concreting, steel plate at the bottom of post is embedded in the end face of cushion cap；
Second step, the steel-pipe pile of welded and installed Φ 63cm on steel plate at the bottom of post, and between the outer wall and steel plate at the bottom of post of steel-pipe pile, weld reinforcement steel plate；Connect system with Φ 32.5cm spiral steel pipe between each steel-pipe pile to be attached, form stable frame structure；Weld capital steel plate in the upper end of each steel-pipe pile, and between the outer wall and capital steel plate of steel-pipe pile, weld reinforcement steel plate；
3rd step, sets up, often arranging steel-pipe pile top, the transverse distribution beam made of double limb I56 I-steel, is more longitudinally laid on each transverse distribution beam by beret truss, connects with beret truss bracing frame between each row's beret truss；
4th step, steel rail laying on beret truss, set up bowl immediately above at rail and buckle support, the model of the cast-in-situ continuous beam being made up of the lumps of wood and template is installed at bowl button support.
The invention have the advantages that described falsework formula waters continuous beam cast-in-place support achieves building in the case of riverbed features as poor geologic condition, whole support system is installed easy and simple to handle, by tearing open conveniently；Steel pipe pile foundation acts on cushion cap, base fixed；Connecting into stable " K " property node between steel-pipe pile, each rod member stress is clear and definite, improves the stability of cast-in-place support.Prove that the steel-pipe pile cast-in-place support of this kind of form achieves support zero sedimentation by example, saved cost 900,000 yuan than other construction methods.
