  RCC Reinforced concrete (RC) (also called reinforced cement concrete or RCC) is a composite material in which the relatively low tensile and durability of concrete is resisted by the inclusion of reinforcement with high tensile strength or ductility. Reinforcement (steel reinforcing bar) (rebar) is usually not required and is passively embedded in concrete before concrete sets. Description Reinforcement plans are typically designed to withstand tensile stress in specific areas of concrete that can lead to unacceptable cracking and / or structural failure. Modern reinforced concrete may contain different reinforcing materials made from steel, polymer or alternative composite materials with or without a combination of rebar. Reinforced concrete can also be stretched permanently (concrete in compression, reinforcement in tension), so as to improve the behavior of the final structure under working loads. In the United States, the most common methods of doing this are known a...

  Pipe Jacking Pipe Jacking Pipe jacking , commonly known as micro tunneling in small diameters, is a technique for installing underground pipelines, ducts and culverts. Excavation inside the shield is done at the same time using powerful hydraulic jacks to push provides flexible, structural, watertight, ready pipeline due to tunnel specially designed pipes from the ground behind the shield. This method excavation.   Although there may be restrictions on practical engineering considerations and economics, there is no theoretical limit to the length of an individual pipe jack . Drives of several hundred meters are easily available in a straight line alone or up to a series of radii or radios. A range of mechanical and remote control installed using the appropriate system. The construction tolerances are excavation systems is available. Pipes ranging from 150 mm to 3000 mm can be comparable to other tunnelling methods, and the pipe jacking method generally similar to tho...
