Atunnel making machine refers to a set of machines that can help build tunnels or underground passages for several purposes. The kind of tunnel required will typically determine the kind of machine used. The following types of tunnel-making machines are typically used:
Drill and Blast Tunnel Boring Machine:
The drill-and-blast tunneling machine bores through the ground using a two-step blasting process. First, it drills small holes into the rock. Then, explosives are put into those holes, and the rock is blasted. This method is good for hard rock areas. It is often used for making tunnels through mountainous regions or deeply buried places. Even though these machines can tunnel through tough rocks, they need extra work and time to clear out the blasted rock before tunneling can continue.
Earth Pressure Balance Shield:
The Earth Pressure Balance Shield is a special type of tunneling machine made for soft or wet ground. It works well in places where the soil may not provide enough support. This EPB Shield is important because it helps keep the tunnel front balanced by using the pressure from the excavated soil. It also protects the tunnel worker from possible flooding or soil cave-ins. Workers can use this EPB Shield safely in areas with loose soil or liquids, like mud or water.
Hydraulic Breaker:
A hydraulic breaker is a hammer that is powered by hydraulic fluid. Its main job is to break up rock or concrete during tunnel construction or other excavation projects. This tool is very important in tunneling because it allows for more precise digging and gives better control when working in confined spaces inside the tunnel. Additionally, the hydraulic breaker can be used effectively in horizontal, vertical, or overhead positions. This versatility means it can access a wide range of locations within the tunnel.
Open-Face Tunnel Boring Machine:
This machine is used when stable soil or rock is present. It has an open cutter head that bores through the material directly. As it tunnels, material is removed from the open face. Once the bore is complete, supportive lining is put in place. This TBM type works well in stable locations but is not good for soft or mixed soils.
Shielded Tunnel Boring Machine:
They are closed at the front and have a cylindrical shell or shield around them. The shield protects the excavated area, especially in loose soils. It provides immediate support. After the machine moves forward, the lining can be added to complete the tunnel. Shielded TBMs work well in any type of soil or rock.
Specification of tunnel-making machines:
Capacity:
The capacity for making tunnels indicates how many tunnels the machine can produce in a given time frame, typically an hour.
Length and diameter:
Tunnel-making machines can construct tunnels of varying lengths and diameters based on their size and capacity. The length and diameter can be adjusted to meet the needs of different projects.
Power:
Power refers to the power output of the tunnel-making machine, typically indicated in kilowatts (KW). This determines the machine's performance and capacity.
Equipment weight:
The weight of the tunnel-making machine affects its mobility and stability during the construction process. Heavier machines provide more stability but are less mobile.
Materials:
Tunnel-making machines are typically made of steel and other durable materials to withstand high-intensity operations and environmental conditions.
Control system:
Modern tunnel-making machines are equipped with automated control systems that allow for remote control and monitoring of machine operation, adjusting parameters such as speed, pressure, and more.
Maintenance:
Regular inspections:
Regular inspections should be performed on the tunnel-making machine to check for wear and damage to key components such as belts, chains, gears, and blades. Any abnormal conditions should be fixed in a timely manner.
Lubrication:
Lubricate the moving parts of the tunnel-making machine, such as bearings, gears, etc., with the appropriate lubricant to ensure smooth operation and reduce friction and wear.
Maintenance of electrical systems:
Ensure that the electrical components and wiring of the tunnel-making machine are in good condition and free of corrosion, loose connections, or damaged insulation. Regular cleaning and inspection of the controller and electrical box should be performed.
Maintenance of hydraulic systems:
The hydraulic system of the tunnel-making machine is responsible for driving its movement and function; therefore, it is crucial to regularly check the hydraulic oil level and quality, replace hydraulic oil filters, and inspect hoses and seals for any leaks or damage.
Cleaning:
Keep the tunnel-making machine clean and remove any dirt, cement residues, etc. that may be stuck to it. Cleaning the machine helps to prevent overheating and ensures good heat dissipation.
Pay attention to safe operation:
When operating and maintaining the tunnel-making machine, safety procedures should be followed and proper protective equipment worn. Also, the operating manual should be read carefully to understand the proper maintenance and operating methods.
Tunnel-making machines are specialized pieces of equipment used for constructing tunnels in various soil categories. The machines are efficient and fast, making them the preferred option in several industries.
Transportation Sector
In the construction of tunnels for subway systems and railway, the construction managers often use tunnel-making machines. The machines ensure that there is a constant and smooth flow of work as well as a timely completion of the project.
Water Management Systems
An industry that highly utilizes tunnel-making machines is the water management sector. The machines help to create tunnels for drainage systems and underground pipelines. With these tunnels made, water authorities can effectively manage the flow of water and lessen the impact of floods during the rainy season.
Mining Industry
Tunnel-making machines create access tunnels to reach mineral deposits like coal, gold, and oil that are located deep underground. The precision of the machines allows for easy and safe access to these areas, minimizing environmental impact and enhancing resource extraction efficiency.
Pedestrian and Urban Tunnels
Tunnel-making machines can construct pedestrian underpasses and urban tunnels. These tunnels enhance urban infrastructure by improving traffic flow and reducing congestion and ensuring pedestrian safety.
How to Choose a Make Tunnel
When shopping for make tunnels, buyers should get models that cater to the needs of their target customers. This can be done by researching what customers expect from a makeshift tunnel for their needs. More importantly, buyers should get models that can withstand the elements and long-term use.
Consider the various materials used to build the make tunnels. For farming and camping purposes, look for heavy-duty PVC, polyethylene, or UV-stabilized polyethylene blush that can withstand harsh environmental conditions. The tunnel's frame material, often galvanized steel or aluminum alloy, should also be long-lasting. A durable make tunnel will hardly get damaged or need frequent repairs and maintenance.
Does the make tunnel have ventilation? In most cases, inadequate ventilation can lead to overheating and suffocation of whatever is inside the tunnel. Therefore, buyers should look for tunnels with side mesh panels, vents, or doors. Buying makes tunnels with ventilation will give business customers an option to ensure adequate airflow.
Consider the portability of the makeshift tunnels. Many models come equipped with stakes and carry bags for easy transportation. This makes it easy for farmers, campers, and outdoor enthusiasts to move the tunnel from one place to another. For permanent structures, look for a make tunnel with anchoring systems for stability.
Get makeshift tunnels in different lengths and widths to suit various applications. Agriculture and construction industries prefer extra-large makes tunnels to accommodate large machinery and crops. On the other hand, campers and outdoor enthusiasts prefer smaller tunnels they can easily carry around.
Finally, buyers should get make tunnels compatible with various crops. They should look for make tunnels with different hoop spacing and heights to accommodate tall crops. Such a model will be more beneficial to the average farmer, thus attracting more sales.
