Semi-rigid-joint integral type abutment bridge supported by concrete pile and construction method
The invention relates to a semi-rigid-joint integral type abutment bridge supported by a concrete pile and a construction method. The semi-rigid-joint integral type abutment bridge supported by the concrete pile comprises an end beam, a pile cap, and a concrete pile which is inserted into the earth surface to be used as a supporting pile; a weak shaft of the concrete pile body is bent to form a semi-rigid-joint structure with the end beam; the semi-rigid-joint structure is that neoprene fills in a joint seam of the pile cap and the end beam, and the pile cap and the end beam are connected through a main rib in the concrete pile; the longitudinal deformation capacity of the bridge is improved through the semi-rigid-joint structure between the pile body and the end beam, the allowable bridge length is increased, and therefore, a pile foundation is avoided cracking due to excessive large pulling stress, the damage of temperature deformation of the bridge to a pile body can be reduced, the vertical bearing capacity of the pile is ensured, and the service life of the bridge is prolonged.
