Structure Component of Transportation Road

Posted on by

Below the structure component of transportation road:

• Transportation road is suitable for the scale of development with an extensive site.

• It depends on local country legal requirements, especially in terms of: width, height, length and weight of transported objects.

• The design must consider the circumstances that created it. If the component does not comply then it requires an additional fee in addition to transportation difficulties requiring special escort officer roads.

• Maximum length of the precast units are hinted at in the transport does not exceed 30 m.

• Freight transport is low (usually for wall and floor panels have the ability to haul 250 tons.

• To transport objects of wall and floor panels are very suitable to use a vehicle equipped with a special frame that can support and protect the transport object.

• For a long object and a greater burden can use two carts are connected by precast concrete itself.

Structure Component of Transportation Prefabricated

Prefabricated unit precast concrete components can be said to be economical only if the cost of transportation from the overall production can be significantly lower than the cost of conventional concrete.

Transport values ​​may be low when pressed in a mechanical engineering improved manufacturing.

There are basically two forms of transportation:

  1. Road transport
  2. Transport by rail

Some things to consider in the selection of transportation

  1. Transport distance – a distance of 200 km economies
  2. Dimensional objects that are transported
  3. Volume of the transported object – a minimum of 400 units
  4. Frequency of transport
  5. Material properties of objects to be transported
  6. Time available
  7. Distribution of construction site
  8. Location of project and accessibility
  9. The cost of available
  10. Legalization of transportation system

Classification of Precast Concrete System

Posted on by

Precast system is divided into two categories:

A. As a component of the structure

  • Concrete piles and a connection system

There are several forms of the stake. The most common form is the square massif, because most easily made. Another variant is a hollow spherical shape (spinning) in a round mold.

  • Prefabricated Floor Plates

In 1984, the components of precast floor began to be known in Indonesia on the construction of the tower BDNI. Commonly used form of plate is prestressed hollow (hollow core slab).

  • Girder Bridge and Road Flyover

This component is very popular because it is clearly easier than the steel structure. The first variant form of void slab, post-tensioning prestressed system, Y-shaped variant, the variant form of post-tensioning prestressed box with the system.

B. As the structure system

  • Bresphaka Systems (1999)

Characteristic of this system is the use of lightweight concrete material for components of the columns and beams. Lightweight aggregate concrete material is made ​​of coarse light gray. Another characteristic is the T-shaped columns and other components of the beam and plate.

  • Concrete Mattress Systems

The solution is to use a concrete mat system that can be installed as deep as that planned by grafting, so it can be obtained by carrying capacity, decline and stability of the desired level.
