Continuous rigid frame aqueduct variable box variable cross section transition beam section structure and design method
The invention provides a continuous rigid frame aqueduct variable box variable cross section transition beam section structure and a design method. The method comprises the construction of a single-box single-chamber box beam, the construction of a transition beam section during gradual change from the single-box single-chamber box beam section to a two-box beam section and the construction of the two-box beam section. A vertical face waterproof layer of a connecting section is arranged between a packing layer and the connecting section. The design method of the vertical face waterproof layer comprises the steps of forming a gap at the contact position of a cushion layer and the connecting section, filling the gap with closed-cell foam boards, forming a notch at the upper end of the gap, stretching a U-shaped GB compounded rubber waterstop over the notch, filling the notch right above the gap with polyethylene caulking boards and two-component polysulfide sealants successively, filling the groove with acrylic emulsion mortar to make the notch and the bottom side of water body space flat. The variable box variable cross section connecting structure is adopted, so that the defects of conventional connecting structure are overcome, the phenomenon of stress concentration of the structure is reduced, the waterproof capability is great and the durability is great.
