Slurry Based Tunnel Boring Machine

Creation of tunnel for multi purposes use made of concrete, which can be apply to different field for different purposes for 8 inch diameter around 200 feet long tunnel unit. Number of tunnel unit can create long communication and transmission path for electricity, gas, water, optical fiber line, telecom, sewerage network etc. The project is capable to create the tunnel underground without interrupting the daily traffic life. The traditional open-cut method for tunnel creation is expensive and time consuming. The proposed prototype is capable to solve all this problem in Bangladesh just by doing this underground without interrupting the daily life over ground.

People affected in many ways_

1. People are interrupted by Open cut method.
2. Gravitational force can not able to apply in open cut method.
3. Open drain causes various virus and mosquitos.
4. In working time for open cut method, traffic jam increases in the road.
5. Road re-construction affect the other part of the roads.
6. Environment pollution occurs.
7. High depth open cut is very costly.
8. Road become congested.
9. Its take long time to make a pipeline under the ground.
10. Pipes cannot be installed in irrespective weather.
11. There is a high chance to lick the pipes when install using open cut method.

12. Irrigation water piping network for agriculture connecting with river is very expensive for firmer in Bangladesh.

Directly and indirectly, around 80% people in Bangladesh are affected by this problem.

This project is funded by service innovation fund(SIF), organize by Access to Information(a2i) program, Prime Minister office, Bangladesh. We made a contract with government of Bangladesh. Where City corporation and Roads and Highway was interested. We communication with them and getting their requirement of machine. We piloted this project under Municipal. Roads and Highway interested to use this machine as a large scale.

This machine will be usable for 

City Corporation: Making Sewerage Network 

Roads and Highway: Underpass in various road crossing.

LGED: Underpass of cannel

Municipality: Sewerage Network

Different Govt. Organization and Non Govt. Organization: Water Supply Network.

Telecommunication DESCO: Underground Cable and fiber line.

WASA: Water supply network

Agriculture sector: Water supply system from river using gravitational force.

Power distribution sector: Underground high voltage electricity line.

Slurry Based Tunnel Boring Machine is a construction machine, which is used to make pipe line under the ground. Without interrupting public tunnel can be construct. Concrete pipe can be used to create tunnel. By installing the machine in a launch shaft, machine will start working. There is a cutter in front of the machine. It cut the soil and transport it to the storage tank which will located over the ground. A control panel will located over the ground and operator operate the machine manually and automatically. A guidance system is used to locate its directional movement. This machine system is very easy to control and simple to understand. By taking training, it is possible to operate this machine by technicians. 

Project output:  

·         No open trenches required – pipes will installed without the general public noticing.

·         Towns and landscapes will never be affected by the construction work.

·         Falls in water table level, which affect vegetation, can be prevented.

·         The amount of soil that needs to be excavated and disposed of will be comparably small.

·         No special storage areas will be needed for materials and equipment.

·         Traffic in road will not be disrupted.

·         Pipes can be installed even in irrespective weather.

·         Residents and nature will be protected against noise, dirt and vibrations.

·         There will be substantially less damage done than using the open-cut method.

·         Carbon emissions will be considerably lower during construction and from traffic, as   congestion can be prevented.

·         Cost will be less than other existing Micro TBM.

There are some technology used to make this machine. Which are, Mechanical parts designing and creating, Electrical wiring, Automation, Construction, Data transfer and monitoring technology, Hydraulic system, Slurry transportation etc.

The proposed machine is a new design in the world. Power consumption and speed of the machine will be higher. The proposed product will be manufactured locally by using local gadgets. It’s an impressive, beneficial and useful product to reach in future quickly. As no company has introduced any such item, it can be treated as an attractive new addition in this field.

newspaper article: There are some news that we collected from news paper of Bangladesh.

Now we are serving few areas. Within 1 year we will serve around 5 district of Bangladesh and in five years we have a plan to serve all division of our country.

We are planning to make a full production system in Bangladesh of this machine. Within 5 years, we will sell our product internationally.

We have some barrier to make a large production setup. We are facing problems to make it more sophisticated. Finance is a main problem here. We targeting world market, but it is difficult for us. We need co-operation to make this machine more valuable. 

We trying to get investor and make a good team to make it more productive. We trying to contract over the world. Big investment is necessary to make a large production environment.

We are 10 people working with this machine.

We have a deal with Access to Information Program. They are not partner but they funded this project for development of our country. We got the Service Innovation Fund 2390000 to innovate this project. Our Project Director is the innovator of this machine. Access to Information Program is an initiate of Bangladesh Government to provide seed fund for innovative project.

Currently we have no partner.

We created our revenue model, cash flow projection, quarterly plan in excel. We don't want to post here. If it is require to analysis on this model, we will provide later. Please consider it for future investigation.

We made an agreement Access to information (A2I), Innovation Team. They will co-operate from Bangladesh Government end. They are working on it to introduce this machine world wide to make a large market place for out business. Here is link as a reference. http://ideabank.eservice.gov.bd/projects/171

To develop our country, tunneling technology is a must. In Bangladesh It necessary to improve clean water distribution system to the people for their good health. Roads become polluted by rain water in the cities. There is no planned sewerage network in our cities. For this reason environment becoming very unhealthy  day by day. We facing financial problem to make a production system of this machine. We need a large team to operate this business, some technical support is also require. Our organization need Investor to scale up this business. If we win the price, it will help us to improve our business in Bangladesh and we will be able to solve the problems what we noted above.

Construction based companies are more related with this business, like Abdul Monem Ltd. Machine building companies are important for this business. I would like to share "10 %" profit of our Slurry Based Tunnel Boring Machine business.
