Cable Bridge Installation Company In Bangladesh

 

What is a cable bridge and why is it needed in Bangladesh?

A cable-stayed bridge is a type of bridge where the deck (the load-bearing portion) is supported by cables directly connected to one or more towers (or pylons). 

But, we are not talking about this kind of cable bridge!

We are here to discuss a bridge that carries electrical cables across a river or canal. Bangladesh is a country where huge river and canal networks exist everywhere. So, during the execution of an underground cable network project random rivers and canals need to cross through the Horizontal Drilling or Cable Bridge method. If you need a well-known and huge experienced company on cable bridge here in Bangladesh, you are in the right place, just relay and ask us.

We have a lot of experience in cable bridge installation works. You can carry out your EPC project smoothly just and we will help you on:

Underground cable crossings through a cable bridge are quite fascinating! Here's a general overview of how it works:

1. Planning and Design

• Site Survey: Engineers conduct thorough surveys to understand the river's depth, flow, and bottom conditions.

• Design: The design includes the bridge structure, the path for the cables, and any necessary protective measures.

2. Construction of the Bridge

• Foundation and Towers: The bridge's foundation and towers are constructed to support the cables and the deck.

• Deck Installation: The bridge deck is installed, often using incremental launching or other methods.

3. Cable Installation

• Conduit Installation: A conduit or duct is installed under the riverbed to house the cables. This can involve digging trenches or using horizontal directional drilling.

• Cable Pulling: The cables are pulled through the conduit using specialized equipment. This ensures they are properly placed and protected.

4. Protection and Maintenance

• Protective Measures: The cables are often encased in protective materials to prevent damage from water, debris, and other environmental factors.

• Regular Inspections: Regular inspections and maintenance are conducted to ensure the integrity and functionality of the cables.

5. Environmental Considerations

• Environmental Impact: Measures are taken to minimize the environmental impact of the construction and installation process.

• Stakeholder Engagement: Engaging with stakeholders, including environmental organizations, to ensure compliance with regulations and best practices.

This method ensures that the cables are safely and efficiently installed while maintaining the structural integrity of the bridge and minimizing environmental impact. It's a complex but well-coordinated process that requires expertise and precision.

Our Completed Project

We have completed Cable Bridge works successfully in many projects for underground cable installation works with EPC contractors like LS Cable and Systek Ltd. for government power transmission and distribution authority in Bangladesh. Our successfully completed Cable Bridge projects are as follows:

01. DESCO 132M long 3 span Steel Structure Cable Bridge on Balu River for crossing 132kV double circuit underground cable crossing;

02. DPDC and PGCB 52M long 4 Circuit steel structure Cable Bridge on Rampura canal for crossing 132kV double circuit underground cable crossing;

03. DESCO 32M steel structure Cable Bridge on Rampura canal for crossing 132kV double circuit underground cable crossing.

03. PGCB 30M steel structure Cable Bridge on Ghorashal Power Plant for crossing 230kV double circuit underground cable crossing.

We also have completed lots of steel structures for the canal crossing of power cables.
