Description

technical field [0001] The invention relates to engineering testing equipment, in particular to a ground hollow drum knocking device for engineering technology testing. Background technique [0002] Hollowing is one of the indicators of engineering quality, and technical determination is often required when studying construction plans. The hollowing of the ground of the house is based on Article 5.3.4 of "Code for Quality Acceptance of Building Decoration and Renovation Engineering" (GB50209-2002), "The surface layer and the next layer should be firmly combined without hollowing or cracks." [0003] Empty drums are caused by the presence of air in the original masonry and powder ash layer. When testing, lightly tap the plaster layer and leveling layer with an empty drum hammer or a hard object. "Drum" generally refers to the empty drum phenomenon that occurs between the floor, wall, and ceiling decoration layer (plastering or pasting brick) and the structural layer (concret...
