Abstract
Description
Technical Field
[0001] The invention relates to the technical field of nuclear power plant construction, and in particular to a water gate gate slot embedded part construction structure and method. Background Art
[0002] There are many types and quantities of embedded parts in nuclear power plants. Among them, the embedded parts of sluice gate slots have large cross-sectional dimensions, heavy weight, and a large number of anchor bars. Under the influence of steel bars and stirrups, it is difficult to install them in place in one go, and the construction accuracy of the embedded parts of sluice gate slots is high.
[0003] The current construction method for embedded parts of sluice gate slots is to install them in the wall as a whole at one time, and then tie steel bars, set up formwork, and pour concrete. This is not only difficult to meet the design requirements, but also time-consuming, labor-intensive, and cost-increasing. In addition, the safety risks of high-altitude construction are also relatively large and cannot meet the precision and quality requirements.
[0004] The Chinese patent application with patent publication number CN 106245598A discloses a planar gate slot embedded component support device and a gate slot embedded component installation method. However, the gate slot embedded component is different from the gate slot embedded component used in nuclear power plants and cannot be used for nuclear power plant water gates. The gate slot bottom sill embedded component has no leak detection conduit at the bottom and cannot be connected to the corresponding leak detection system. The gate slot track embedded component is irregular and is easily deformed when cast with concrete. It cannot meet the sealing requirements in ultra-high radiation areas (>100mSv / h). The groove part formed with the concrete easily forms a dead angle structure, causing radioactive impurities to accumulate; and the gate slot embedded component also has the following problems: Problem: No anti-floating measures have been taken for the embedded parts at the bottom sill of the gate groove, and the accuracy cannot be guaranteed; the flat gate gate groove embedded parts support device, the adjustable support rod between the orifices is connected to the gate groove track embedded parts with bolts through the flange base at its end, and the force points of the embedded parts are concentrated at the connection part with the flange base, which can easily cause uneven force and deformation of the embedded parts. At the same time, screw holes for bolts are required on the gate groove track embedded parts, and only screw plugs are used to seal them, which has a great impact on the integrity and sealing of the embedded parts; the flat gate gate groove embedded parts support device occupies the entire gate area, and an operating platform needs to be set up separately. When the gate groove is wide, it is difficult to pour concrete in the middle of the gate groove. Summary of the invention
