Description

Construction device and method for radiation protection machine room Technical Field The invention belongs to the technical field of building construction, and particularly relates to a construction device and a construction method of a radiation protection machine room. Background With the rapid development of medical imaging technology, medical linacs are also widely used in surgical radiotherapy as a device for treating tumors. However, the medical linear accelerator has large energy output and strong radiation force, and brings negative effects while improving the operation quality, wherein the most serious problem is the problem of X-ray radiation pollution of an operating room, and in order to prevent the damage of the radiation of the linear accelerator to human bodies, the top plate and the wall plate of a machine room of the linear accelerator are ultra-thick large-volume concrete structures, the construction process is complex, and special construction tissue design needs to be made in advance to meet the design requirement. Because the anti-radiation concrete structure has the characteristics of large volume, super thickness, large unit volume and the like, the anti-radiation concrete structure relates to high and large formwork engineering, requires a formwork supporting system to have enough bearing capacity, rigidity and stability, can reinforce the formwork engineering by arranging a split bolt on the basis of the traditional formwork and supporting system in order to ensure the safety of the formwork engineering, and generally, the anti-radiation concrete structure is inevitably provided with a wall bushing or a reserved hole of the structure for the pipeline to pass through during subsequent construction, such as a water pipe, a cable and the like. The parts such as the split bolt holes, the wall bushing, the reserved holes of the structure and the like become weak links of the whole radiation protection system, and have larger hidden troubles of radiation leakage. A patent of China patent application CN113638598B discloses a split bolt of a radiation-proof concrete reserved labyrinth hole and a construction method, and the split bolt is technically characterized in that a wall bushing, a structure reserved hole and a split bolt structure related to a radiation concrete template are combined, the number of weak parts in the radiation-proof concrete structure is reduced, the radiation leakage risk is fundamentally reduced, a non-through fold line structure is adopted for an embedded bushing, a radiation-proof coating is sprayed on the inner side, the radiation leakage is effectively prevented through the arrangement of the labyrinth embedded bushing on the basis that the normal function of the wall bushing or the structure reserved hole is not affected, a protective sleeve is arranged at a port of the embedded bushing, good slurry stopping and limiting effects are achieved, the installation efficiency is improved through the arrangement of a reinforcing steel bar connector, the pipeline operation is shortened, the construction period is shortened, the split bolt of the radiation-proof concrete reserved labyrinth hole and a conventional split bolt work together, the stress rationality of the radiation-proof concrete structure template system is greatly improved, and the safety of high and large template engineering is guaranteed. However, the prior art has the defects that the wall bushing, the structure reserved hole and the split bolt are combined together by the reserved split bolt structure in the prior art, so that the number of weak parts in the anti-radiation concrete structure is reduced, but the structure needs to be filled with the anti-radiation material after the recyclable screw rod is taken out, and then if the pipeline is damaged and needs to be replaced, the pipeline is difficult to replace due to the fact that the anti-radiation material is fixedly connected in the embedded bushing, and the secondary threading work is seriously influenced. Therefore, the invention provides a construction device and a construction method for a radiation protection machine room. Disclosure of Invention In order to overcome the deficiencies of the prior art, at least one technical problem presented in the background art is solved. The invention solves the technical problems by adopting the technical scheme that the construction device of the radiation-proof machine room comprises a template, an embedded sleeve, a steel bar connector, an embedded screw, a recyclable bolt joint, a water stop sheet, a wooden support, a fastener and a nut, wherein the embedded screw and the recyclable screw are connected with the steel bar connector through threads; The anti-radiation sleeve comprises a filling sleeve, wherein an anti-radiation material is arranged in the filling sleeve, through holes for a pipeline to pass through are formed in the filling sleeve and the anti-radiation material, and a fixing assemb
