Two-lane beam-bridge end reinforcement concrete frame pier in side walk

Abstract

The invention discloses a two-lane beam-bridge end reinforcement concrete frame pier in side walk. The pier consists of a frame type bearing platform and a frame type retaining wall, wherein the frame type bearing platform consists of a bottom-up transverse platform, two bottom-up vertical platforms and a plurality of bottom-up suspension binding beams; the transverse platform, the two vertical platforms and the plurality of suspension binding beams which are arranged on two ends of the two vertical platforms and are arranged into rows up and down form a crisscross shaped vertical planar graph structure; the frame type retaining wall is an opening frame wall body consisting of a connecting wall, a wing lug wall and a wall-attached wall; the frame type bearing platform, the frame type retaining wall are positioned on the same bearing platform foundation; and the wing lug wall and the wall-attached water are respectively connected with wall-attached columns. Compared with the concrete solid pier, the reinforcement concrete frame pier can save 34.25 percent of construction cost, the wing lug wall and the wall-attached wall both adopt the wall-attached columns for reinforcement so as to further ensure steady performance and extrusion resistance of the frame structure, and compact the filling to prevent damage and loss.

Description

Technical field: [0001] The invention relates to a road and bridge building component, in particular to a two-lane beam-type bridge end reinforced concrete frame abutment suitable for the joint between the pier caps at both ends of a bridge with a single span of 20 to 30 meters and the road surface. Background technique: [0002] With the development of the national economy and the needs of people's lives, more and more first-class roads, second-class roads, ordinary roads and expressways need to be built. At the same time, it is necessary to cross obstacles such as rivers and canyons during the construction of roads. Therefore, the erection and construction of bridges is an important project for highway penetration. At present, in order to make the built bridge stable, both ends of the bridge are contacted with the road surface with concrete pier or bridge end slope, but the application of such solid concrete pier and bridge end slope causes cement and steel Waste, also ea...
