Semi-integral seamless slope bridge head structure
The invention discloses a semi-integral seamless slope bridge head structure which comprises a main beam, a semi-integral bridge abutment, a bridging slab, a ground anchor beam and an approach pavement, wherein the main beam and the bridge abutment adopt separate structures; the main beam is placed on the abutment cap of the bridge abutment through a support seat; a bridge abutment back wall is also arranged on the semi-integral bridge abutment; the near-abutment end of the bridging slab is connected together with the main beam through main reinforcement; the ground anchor beam is arranged at the far-abutment end of the bridging slab, and the ground anchor beam and the far-abutment end of the bridging slab form an integral through pouring; the ground anchor beam extends into a ground base layer; one or more layers of steel reinforcement are arranged in the bridging slab; each layer of the steel reinforcement downwards extends into the ground anchor beam; the approach pavement is continuously spread on the main beam and the bridging slab. The semi-integral seamless slope bridge head structure has the advantages that the deformation of the main beam is absorbed by a deck expansion joint at a relatively high elevation, and a slope base bridge head of a slope bridge does not deform, so that no expansion joint needs to be formed in the slope base bridge head, and then the maintenance cost and the noise pollution are reduced.
