The application of the epoxy grout in demolition of reinforcement technology

Demolition of reinforcement process: support unloading - - - Wall - of foundation reinforcement - - Angle steel welding column - - The preset Angle beam ( Lattice beam) - - - Casting high-strength non-shrinkage epoxy grout - - - Settlement observation - - - Demolition of 18 # main wall of a layer of roof beams and the jack, for effective support, to remove the live load on the original building. The original brick concrete set of technology on strip foundation, to broaden the base of the primary, widen the specific size after detailed calculation. Column section size is calculated to determine, Angle should extend to the bottom of the base platform, and increase the hoops strengthen Angle and new steel welding. In the original wall lofting determine size and position, along the wall brick joints embedded groove Angle, 20 cm intervals into the steel wedge, Angle steel, drilling with bolt clamping. Device template pouring epoxy grout, make Angle between the masonry and effectively combine to form the whole. When CGM epoxy grout strength to strength, dismantling templates, remove steel wedge, pull down a layer of brick, 1000 mm intervals do settlement observation point, new beam without settlement changes after 72 hours, can remove the beam under the wall.
