Bridge Construction Company in Bangladesh

Bridge, structure that ranges on a horizontally between supports, whose capacity is to convey vertical loads. The prototypical bridge is very straightforward—two backings holding up a beam—yet the designing issues that should be overcome even in this basic structure are inherent in every bridge: the supports should be sufficiently able to hold the construction up, and the range between supports should be sufficiently able to convey the loads. Ranges or spans are generally made as short as possible; long spans are defended where acceptable establishments are restricted—for instance, over estuaries with profound and deep water.

All significant and major bridges are constructed with the public’s money. In this manner, bridge design that best serves the public interest has a triple objective: to be as effective, as conservative, and as rich as is safely possible. Productivity is a logical rule that puts worth on diminishing materials while expanding execution. The economy is a social rule that puts value on lessening the expenses of construction and maintenance while holding effectiveness.

Finally, elegance is a representative or visual principle that puts value on the individual articulation of the designer without trading off execution or economy. There is little conflict over what comprises proficiency and economy, yet the meaning of a class has consistently been questionable.

Main Parts of a Bridge Construction

Let’s look at the main parts of a bridge in more detail and consider the components that make up the three core areas:

Materials Used for Bridge Construction

Some of the main materials found on construction of a bridge are steel, concrete, stone and asphalt. Other materials include iron, timber, aluminium, rubber and other joint materials. Below is a description of some typical uses for these materials in a bridge construction.

Types of Bridges

Arch Bridges

There are various types of curve bridge yet they all share focal components for all intents and purpose. Each bridge has abutments, which are used to help the bended arch structure under the bridge. The most widely recognized sort of arch Bridge is a viaduct, a long bridge made of numerous arches.

The sidelong pressing factor made by the arch span is moved into the supporting projections. It is in this way fundamental that these pieces of the scaffold stay strong, flawless and very much established.

Truss bridges

The truss bridge has been around for in a real sense hundreds of years and is a load-bearing construction which fuses a support in a profoundly proficient yet basic plan. You will see a variety of several varieties of the basic support bridge yet they all fuse three-sided areas. The part of these three-sided components is significant in light of the fact that they viably assimilate pressure and pressure to make a focused on structure ready to oblige dynamic burdens. This combination of pressure and pressure guarantees the design of the bridge is kept up and the decking area remains positive even in generally strong winds.

Cantilever bridges

At the point when the primary cantilever bridge was designed it was viewed as a significant engineering breakthrough. The bridge works by using cantilevers which might be straightforward pillars or supports.

They are produced using pre-focused on concrete or underlying steel when used to oblige traffic. At the point when you consider that the even bars making up the cantilever arm are just upheld from one side it starts to sound somewhat risky.

Beam Bridges

A beam bridge is probably the simplest kind of bridge. An ideal example being an essential log bridge – something you may see while out on a nation walk.

The deck region generally comprises of wood board or stone slabs (regularly alluded to as a clapper bridge). These are supported either side by two beams running between projections/piers

Suspension Bridges

The construction of a stereotypical suspension bridge looks basic however the plan is very viable. The deck of the suspension bridge is the load-bearing component of the design. This is held set up by vertical suspenders which support the cables. The suspension cables extend out past each side of the bridge and are secured immovably into the ground.

Tied Arch Bridges

The tied arch bridge is an intriguing design which fuses a curve structure (generally metal) supported by vertical ties between the arch and the deck. The tips of the arch structure are associated by a bottom chord. This demonstrates also to the line of a bow. The descending pressing factor from the arch design to the deck of the bridge is converted into strain by the upward ties. Numerous individuals expect that the projections guarantee that the tied arch bridge and arch structure stay in space.

Cable-Stayed bridges

A cable stayed bridge is dependent upon towers/pylons which are the load-bearing element of the structure. Cables are bridged from the pylons to the deck below. This is the feature many people associate with cable stayed bridges. This type of structure tends to be used for distances greater than those achieved with a cantilever bridge design but less than a suspension bridge.

Different Methods of Bridge Construction

Described below are the different methods in the construction of bridges.

This method is an adaptable and flexible method for bridge construction where complex and uncommon mathematical states of dams can be built without any problem. In circumstances when it is difficult to transport prefabricated components either because of size or inaccessibility, this method is a decent choice. Bridge Construction Company will help you to construct a bridge applying this method.

This method is used for constructing bridges range 50 to 250m. The bridge constructed can either be cast-in-place or precast. Here, the portions are attached in an elective way at far edges of the cantilevers supported by piers. This is the most ideal decision for the construction of long-span length bridges, sporadic length, and cable-stayed bridges.

In this method, the bridge is constructed with the assistance of precast substantial components. The construction is acted in various methods. The precast components include:

A. Precast Beams
B. Precast Decks
C. Precast Segmental Decks

This method is related with the cantilever construction strategy however with much progression in the procedure, it is considered as generally monetary and fast in construction. For long bridges and viaducts with an individual span up to 60m, the strategy is feasible. Decks are started at one abutment and constructed persistently by putting sections to the opposite end of the bridge. Sections can be situated by either a transitory remaining pole framework through more generally using a get together support.

The Incremental Launching Method (ILM) method for bridge construction is used predominantly for the construction of constant substantial bridges or steel support spans. The method performs the procedure in increments. With this method of construction, the bridge deck is underlying areas by pushing the design outwards from a projection towards the pier. The ILM method can be used for bridge decks with a length more noteworthy than 250m.

In the cable-stayed method of construction, cables are used to convey the bridge deck from one or the two sides of the supporting tower. The cables convey and move every one of the loads to the foundations. Cable-stayed method of construction is used for constructing bridges that span more than 300m.

Arch shaped bridge construction is quite possibly the most conservative decisions when the bridge under consideration is needed to get over scenes that are distant. Many modern arch construction methods have made arch construction more efficient. The arch construction can be worked with concrete or pre-cast concrete. The cast-in-situ free cantilever methods and slip-framed areas are two primary construction procedures going under arch methods.

Factors Affecting Selection of Bridge Construction Methods

Before a bridge can be built an appropriate method of construction must be chosen. The decision is made by the design team. The principle factors considered by the design team when choosing a suitable method of construction are given below:

  • The scale of the bridge
  • The obstacles to be crossed
  • The regularity of the span lengths
  • The horizontal and vertical profiles of the bridge decks
  • The nature of the soil strata
  • The local weather
  • The local cost of materials
  • The local labor markets
  • The accessibility of the site
  • The time allowed for construction.

After the meeting and planning about the bridge construction, we along with our clients go to the construction site for seeing the place where the bridge will be construct. Visiting a real time construction project allows to develop a greater understanding of the bridge construction. Based on the location and the condition of the waterways and soil of the areas, the bridge design will be edited and developed.

The initial phase in any bridge construction is appropriate planning and evaluating the necessities which is proposed to serve. Local soil condition both current and future ought to be contemplated, and a cost-effective analysis should be performed by private organisations to ensure they will actually receive good value for their investment in construction.

The execution phase turns the construction plan into action. Our expert engineering team carries out all the planned activities, constructs deliverables, and presents them to project stakeholders. Effective communication plays a huge role during execution of the bridge construction. We ensure that the budget stipulated in the planning stage that should be followed strictly.

Over time, waterway and environmental effects will damage bridge piles and other part of the bridge which require rehabilitation.
