More on Duct Bank Contractor - Roseville, CA

• Design

Duct banks are a compilation of conduits buried inside the soil and often covered in concrete to protect cables that connect to buildings. Basically, they are PVC conduits. They therefore act as enclosures for power and communication wires. The electric cables are inserted inside the PVC conduits which are then piled up. The bundled conduits are then protected with metal encasing and concrete. They are then buried underground to form a consolidated and centralized wiring system.

• Benefits

It’s no brainer that a huge building needs tremendous wiring systems. Construction of duct bank is geared towards protection of cables in the exterior parts of a building. They assimilate the wires into a single channel and conceal them. This process of integrating cables makes things easier in future construction works. Duct banks are used in underneath cabling of parking lots and roads. Also they enable homeowners to replace or enhance the prevailing wiring without the need for excavating the all perimeter lines.

• Construction

Since conduits are of different sizes, duct banks are designed differently. Every conduit has PVC pipe that holds the building cables. The reason why conduits are bundled together is to protect them from water damage and other physical damages. A protective cover is added for safety. At the point of intersection between the building and the wiring system is a unique structure- manhole. The manhole is designed in a way that it inhibits water entry into the building while at the same time enabling the conduits to contract and expand safely without spoiling the duct bank.

• Types of Materials for Duct Banks

Standard materials include concrete which is used as an outer protectant that encases the PVC conduits. Metal (steel) casings are the other common protective materials used especially in pavements. Between the protective materials (concrete or steel) and the conduits are PV spacers that separate the two. Sand is often used as filler element that creates balance in the duct bank and further protects the conduits.

• Construction Methods

Special preparation of trenches for installation is required in order to achieve sufficient support from the ground. If concrete is to be used, the tunnels should be well-established using firm materials that can withstand pressure of the heavy duct bank while at the same time allowing for proper drainage. Cables are mounted once the duct bank is fully installed. Guide wires are used to draw wiring cables via conduits. This method facilitates enhancement and repairs without digging too much into the ground.

• Duct Separators

The separators or spacers protect ducts from sagging and deforming. For every 20 feet of the duct line, 5 spacers are used. During pouring of concrete, the spacers should be secured to the ducts and the soil to avoid floating.

• Pouring Concrete

Concrete should be used carefully to prevent formation of empty spaces in between conduits or below them. However, heavy felling of concrete should be avoided on ducts. A plank should be used to distribute concrete at the lower sides of the banks all the way to the bottom of the tunnel. Force should not be applied during this process and concrete should be allowed to fill all spaces evenly. Pouring of concrete should be a continuous application form one end to the other.

• Construction Schedule

Clients should expect a major project to be completed in a period of 4 months tentatively. An experienced contractor can be in a position to install about 150 feet cable system every day.
