This invention relates to the field of landscape bridge technology, and discloses a V-shaped pier-truss cable-stayed composite bridge structure and its construction method. The V-shaped pier-truss cable-stayed composite bridge structure includes piers, main beams, bridge towers, and cables. The piers include V-shaped main piers. The load of the main beam is transferred to the truss structure via the cables through the cable-stayed towers. The truss structure then transfers the force to the V-shaped main piers. The V-shaped piers provide support and constraint to the main beams through their rigid frame action. Thus, through the interconnection and support between the rigid frame structure, truss structure, and cable-stayed structure, the overall stiffness of the combined bridge structure is greater than the sum of the stiffnesses of the individual structures. This optimizes the stress on the cable-stayed towers and the overall bridge structure, allowing the V-shaped pier-truss cable-stayed composite bridge structure to reduce the tower height compared to existing cable-stayed bridges for the same span, thereby meeting the building height requirements of urban planning or enabling it to be suitable for larger bridge spans.

The utility model discloses a template trolley's variable width adjusting mechanism has the following beneficial effects: provide the variable width adjusting mechanism of trolley, this variable width adjusting mechanism includes variable width adjusting oil cylinder, pull structural member, locking device and variable width filling template, compared with the full hall formwork support frame system of disc buckle type steel pipe support erection of prior art, the utility model can conveniently realize the variable width adjusting of template trolley through variable width adjusting mechanism, and repeatedly set up and dismantle the formwork support frame is not needed, and safe and efficient make template trolley can be adjusted to the design width quickly, tunnel inner contour control is accurate, satisfy the construction requirement of flat curve gradual change widening section, and template trolley space stiffness is big, and the incidence of running formwork, wrong formwork and wrong seam is low, and concrete pouring quality is high, can solve the situation that variable cross section open cut rectangular frame tunnel construction must adopt full support to carry out structure width adjustment, make the full section trolley construction variable cross section open cut rectangular frame tunnel become possible.

The utility model discloses an ultra-thick shear wall template supporting structure, which relates to the field of building construction, and adopts the technical scheme that the ultra-thick shear wall template supporting structure comprises two templates, a plurality of vertical battens are arranged on the sides, far away from each other, of the two templates, and a plurality of steel brackets are arranged on the sides, far away from each other, of the two templates; every two adjacent steel supports are connected through a plurality of square steel pipes. Every two opposite steel supports are connected through a plurality of water stop screws, and the water stop screws penetrate through the two formworks and the corresponding battens. The steel support is fixed to foundation slab concrete through foundation bolts. The steel support has the advantages that the steel support is fixed through the foundation bolts, the space rigidity of formwork supporting is increased, and enough counter-force supporting formworks are provided by being matched with the square steel pipes in use; the water stop screw mainly plays a role in fixing and pulling to a certain extent; and the triangular steel bracket is used for providing enough counter force, so that the use of a large amount of screws is reduced.
