专利汇可以提供Inspecting method of gap generated in outside wall of concrete structure专利检索,专利查询,专利分析的服务。并且PURPOSE:To grasp an injection quantity and an injection place, and to inspect a size of a gap by injecting a resin mixed with a heavy metal, into the gap such as floating, a crack, etc. of the outside wall in a concrete structure, and photographing a radiation photograph. CONSTITUTION:Powder of a heavy metal for absorbing a radiant ray, such as lead, iron, copper, etc. is mixed into a packing material of an epoxy resin, a synthetic resin emulsion, etc., and this packing material 7 is injected into a gap of concrete 1 and mortar 2. After the packing material 7 is hardened, X rays are generated from an X-ray source 4, and an X-ray image of a part executed a repair work is photographed on a film 5. In this case, the X-ray absorbing quantity is varied stepwise, the X-ray absorbing quantity in each hierarchy is photographed simultaneously by placing a known standard tone device 6 side by side, and an image of this tone device 6 is compared with an image of the packing material, by which a packing quantity and a packing state of the packing material, a sticking state of the concrete and the mortar, etc. can be grasped.,下面是Inspecting method of gap generated in outside wall of concrete structure专利的具体信息内容。
