The nuclear island is one of the most important constructions of a nuclear power station. Now the construction of the nuclear island still uses traditional wood or steel formwork. Traditional wooden formwork construction takes a long time and consumes a lot of wood, and steel formwork are heavy and difficult to construct. The outer scaffolding is still traditional buckle scaffolding, the buckle installation efficiency is low, and the buckle will have a slippery center of gravity.
Let's take a look at the KITSEN solution for Nuclear Power Construction
1.Outer Climbing Formwork Solution
1) Vertical Structure: Hydraulic Climbing formwork device for Nuclear Island
A single-walled hydraulic climbing formwork is designed for the outer wall of the nuclear island. The system is suitable for the internal structure of the inner wall of the steel cylinder (the formwork cannot be connected with tie rod).
The height of one pouring is 2000mm, which is driven by hydraulic power to reduce the number of lifting machinery and improve construction efficiency.
2）Inner/Outer Aluminum Wall Formwork
1- The exterior wall panels are assembled together and suspended on a hydraulic climbing device.
2- High loading capacity, reaching 60KN/m2.
3- Large rigidity, no need to install the aligners during the construction process.
4- All aluminum formwork or aluminum/ply formwork can be selected according to different construction projects.
1）Horizontal: 3D early-stripping system
1-Suitable for buildings with different openings and different heights
2-Safe, efficient, environmentally friendly and energy efficient.
3-Convenient storage and transportation.
4-High strength and low cost, replacing the traditional technique.
5-Fast and convenient, one person can assemble 25~50m2 per day
1-Large single block and good integrity. Vertical molds make it convenient to dismantle and time-saving.
2-Flexible adjustment and positioning.
3-Good economic returns as it comes with a working platform.
4-The climbing of the cantilever pylon formwork needs to be achieved by lifting the crane.
The Taishan Nuclear Power Reservoir dam is a rolling concrete gravity dam with a dam crest height of 51 meters. The dam corridor has a total length of 313.55 meters and the bottom surface is 40 meters thick. The back water surface is at an angle of 52 ° to the horizontal plane and changes to a vertical plane at 40.58 meters. The overflow dam is arranged in the overflow dam section in the middle of the gravity dam. The overflow dam section has 5 holes and the net width of each hole is 10 meters. It is an open free overflow weir.
The crane can be driven and parked on the top of the dam construction dam, so the cantilever pylon formwork is used.
