  • Construction method for radiation-proof concrete hole reserved split bolt
    Patent number: 12252889
    Abstract: A construction method for a radiation-proof concrete hole reserved split bolt includes: 1) mounting a hole reserved sleeve; 2) mounting an inclined recoverable split bolt; 3) mounting an inclined split bolt; 4) fixing the inclined recoverable split bolt and an inclined split bolt main body; 5) pouring concrete, and dismantling related components; 6) plugging the inclined split bolt main body; and 7) plugging the hole reserved sleeve. According to the construction method, the hole reserved sleeve is obliquely arranged, the inner side of the hole reserved sleeve is sprayed with a radiation-proof coating with the functions of reducing radiation ray reflection and absorbing certain radiation rays, and in addition, after the construction of a pipeline or a line in the hole reserved sleeve is finished, the openings at both ends of the hole reserved sleeve are plugged with a radiation-proof mortar incorporated with a micro-expanding agent and a waterproof agent.
