The invention relates to the field of building demolition, in particular to a construction method and equipment for bridge demolition. The construction equipment for bridge demolition comprises a sliding column and swing rod assemblies, and the sliding column extends in the front-back direction; there are multiple swing rod assemblies, each swing rod assembly comprises a rotation stopping sleeve, a swing rod, a guide rod and two telescopic blocks, and the rotation stopping sleeves are installed on the sliding columns in a sliding mode; the upper end of the swing rod is rotatably mounted on the rotation stopping sleeve, jacking columns are arranged on the front side and the rear side under the rotation center of the upper end portion of the swing rod, the upper end of the guide rod is rotatably mounted at the lower end of the swing rod, and a guide hole is formed in the guide rod; the two telescopic blocks are symmetrically arranged on the front side and the rear side of the swing rod. and the telescopic blocks extend out under the action of the pressure spring and withdraw under the extrusion of the support column; the centers of the telescopic blocks are all located on the left side under the rotation stopping sleeve, the swing rod on the leftmost side is determined to be the swing rod closest to the vertical state in the static positions after the multiple swing rods swing, and then the guide rod is rotated with the swing rod as the reference to drill holes along the guide hole.
Description
technical field [0001] The invention relates to the field of building demolition, in particular to construction equipment for demolishing bridges. Background technique [0002] Bridge construction is based on reinforced concrete. When demolishing bridges, blasting will be used. Precise blasting must be realized during blasting demolition. Holes should be drilled and embedded in the load-bearing parts of bridges. Blasting damage and The direction and range of throwing requires strict control of the direction and depth of the hole when drilling. Therefore, a construction equipment for bridge demolition that can assist drilling is needed to ensure the precise placement of the charge pack. Contents of the invention [0003] The invention provides a construction method and equipment for demolishing bridges to solve the problem of precise placement of medicine packs. [0004] A construction method and equipment for demolishing a bridge of the present invention adopt the followi...
