Continuous beam dismantling construction method

Abstract

The invention discloses a continuous beam removal construction method, which relates to the field of building construction. The continuous beam removal construction method includes: 1. construction preparation; 2. bridge deck system removal; 3. support locking; 4. bracket erection; 5. Box girder cutting; 6. Demolition of beam blocks; 7. Demolition of bridge piers. First remove asphalt, anti-collision wall and other bridge deck facilities, then set up brackets to cut box girders, and finally hoist beams and chisel out bridge piers to ensure construction safety and efficiency. Professional commanders are set up during the construction process, and operators obey the commanders. Instruct construction to ensure safety.

Description

technical field [0001] The invention relates to the field of building construction, and more specifically, the invention relates to a continuous beam removal construction method. Background technique [0002] In construction, bridge, aviation and pipeline projects, it is often encountered that a beam has three or more supports, called a continuous beam, and a continuous beam has an intermediate support, so its deformation and internal force are usually higher than those of a single span. The beam should be small, so it is widely used in engineering structures. [0003] Continuous beams are mostly made of reinforced concrete and are often used to manufacture bridges. The clearance under bridges is generally greater than 4m, the structure is stable, and the continuity is good. It is very difficult to dismantle continuous beams. Traditional demolition construction methods cannot safely dismantle continuous beams. Contents of the invention [0004] The problem to be solved by...
