Construction method for radiation-proof concrete hole reserved split bolt

A construction method for a radiation-proof concrete hole reserved split bolt, comprising the following steps:

• step 1):
• before pouring is performed to form an underground radiation-proof concrete structure, adopting the radiation-proof concrete hole reserved split bolt;
• binding reinforcing bars of a structure to be concreted, mounting a first template on a first side of the structure to be concreted, and then mounting a hole reserved sleeve;
• step 2):
• penetrating an inclined recoverable split bolt through the hole reserved sleeve, the first template and a first supporting edge, and fixing a first end of the inclined recoverable split bolt through a first wedge-shaped fastener and a first nut;
• step 3):
• fixing a first end of an inclined split bolt main body on the first template and the first supporting edge through a sealing ring, a recoverable bolt joint, a second wedge-shaped fastener and a second nut;
• step 4):
• mounting a second template on a second side of the structure to be concreted, penetrating the inclined recoverable split bolt through the hole reserved sleeve, the second template and a second supporting edge, and fixing a second end of the inclined recoverable split bolt through a first wedge-shaped fastener and a first nut, fixing a second end of the inclined split bolt main body on the second template and the second supporting edge through a sealing ring, a recoverable bolt joint, a second wedge-shaped fastener and a second nut, so as to fixedly mount the second end of the inclined recoverable split bolt and the second end of the inclined split bolt main body on the second template and the second supporting edge on the second side of the structure to be concreted, and tightening the second end of the inclined recoverable split bolt and the second end of the inclined split bolt main body in a split manner;
• step 5):
• pouring concrete;
• after a strength of the concrete reaches a predetermined strength, dismantling the first wedge-shaped fasteners and the first nuts for fixing the inclined recoverable split bolt, and pulling out the inclined recoverable split bolt in the hole reserved sleeve;
• dismantling the recoverable bolt joints, the second wedge-shaped fasteners and the second nuts for fixing the inclined split bolt main body;
• and dismantling the first template and the second template;
• step 6):
• cleaning up floating dust and construction waste in bolt holes at opposing ends of the hole reserved sleeve and the inclined split bolt main body;
• and plugging the bolt holes at the opposing ends of the inclined split bolt main body with a radiation-proof mortar incorporated with a micro-expanding agent and a waterproof agent to obtain plugged bolt holes, and spraying a radiation-proof coating on surfaces of the plugged bolt holes and the sealing rings;
• and
• step 7):
• after a construction of a pipeline or a line in the hole reserved sleeve is finished, plugging openings at opposing ends of the hole reserved sleeve with the radiation-proof mortar incorporated with the micro-expanding agent and the waterproof agent to obtain plugged openings, and then spraying the radiation-proof coating on surfaces of the plugged openings at the opposing ends of the hole reserved sleeve.
