System between sealed bolts (buried)
In the hydraulic structures that need to be sealed, it is used in buried bolts. This type of bolts is once in use and remains in the concrete
There are two types:
A) Between the bolt, the spring seals, which can be adjusted to the thickness of the wall, can be changed by external bolts (when using the sidelong belt, use a 50 cm outer bolt).
And when the vertical backs of the pair of scaffolding pipes are used, the outer bolt of 35 cm is used) and the nut and washer will be attached to the back of the vertical bands.
Cast iron whose size is constant and will be connected to the backs of the vertical bolts with all threads, beads and washers.
B. Repetitive Bolt Systems or Double Gear Bolts:
Double-headed bolts for non-watertight or sectional walls, such as shear walls, where the installation of holes in concrete is technically problematic and is proportional to the thickness of the wall, and with the beads and
The washer is attached to the back of the vertical bundles.
Calculations and Design of Bolt: Hydrostatic Pressure due to Concreting: Assuming that the concrete speed is m / hr and the concrete temperature is in degrees centigrade.
