Tunnel Boring Machine Slurry System of Kosun on Soft Ground

Tunnel Boring Machine Slurry System

Tunnel Boring Machine Slurry System of Kosun with more than 20 years experience.
Three main types of tunnel boring machine separators are used in soft ground excavations-
–   Slurry shield TBMs
–   Earth pressure balance machine
–   Open – face type
In soft grounds with pressure less than 7bar, earth pressure balance machines are used. These along with cutting head also comprises tungsten carbide disc cutters, cutting bits and hard disk cutters.

Machine derives its name from the fact that it balances the pressure in tunnel head by use of excavated earth. Rate of excavation and advances through Archimedes screw controls pressure in the cutterhead. Some additives like bentonite may have to be injected to increase the stability.

Kosun Tunnel Boring Machine Slurry System — Tunnel Boring Machine Slurry System

These are also added to make sure that the earth is sufficiently attached to the Archimedes screw thus marinating the pressure in the head and prevent seepage of water in the tunnel.

Slurry shield TMBs are used in cases where the ground is so granular in nature that it cannot form plug in Archimedes screw. The cutting head is feeded with slurry which in turn applies pressure. This even acts as transporting medium as it mixes with excavated earth and is being pumped out in slurry separation units usually located out of tunnel. In this separation unit slurry is processed so that it is recycled and can be used again. This filtration is a multi- staged process. However, filtration of slurry depends on the size of excavated particles.

Thus making this slurry shield tunnel boring machine separation units suit able for clays and silts sized particles as they are smaller than bentonite particle, which makes the slurry. In these instances separation with water can be done which will help form clay cake thus filtering the slurry in the end.

In grounds where the excavated tunnels can stand without support for a little period, open face TMBs can be used. These tunnel boring machine separators are generally used where strength is more than 10Mpa and seepage of water is low. Cross sections of sizes up to 10 meters can excavated with these TMBs.

Cutter head excavates within 150mm of the shield edge. This shield is moved forwards and cut the ground in same circular manner. Pre-casted concretes or graphite iron segments provide ground support. The key spreads the rings until it is tightly fitted against the tunnel made by tunnel boring machine separators shields. Open face TMBs comes in many variations.

Soilmec Slurry System Good Performance by Kosun Manufacturer

Soilmec Slurry System

Soilmec slurry system stations are a prerequisite for the successful application of mud-water tunneling equipment, such as AVN equipment, hybrid shield machines or sunken shaft boring machines.

The excavated dregs are separated from the bentonite suspension (a mixture of water and thixotropic clays) and removed by efficient and continuous processes. After the separation of the suspension back to the mud ring re-use.

The less the residual moisture, the lighter the weight of the residue to be separated, the lower the cost of the slag. In addition, in the sand and cohesive soil tunneling, if the suspended particles in the residual particles, will be due to mud suspension adsorption of solid particles to reduce the ability to reduce the tunneling speed. In this case, use a filter press and a centrifugal separator to avoid muddy mud.

Tunnel Boring Machine Slurry System Measure Performance

Tunnel boring machine slurry system has a good effect on the mud produced in the shield construction. KD series TBM slurry system is the module system structure.

Tunnel boring machine slurry system is designed to handle the various muds used in common shield construction techniques.It is advisable to check and measure the performance of tunnel boring machine separations they are brought into use. These are important to know the penetrations and also the cutter cost.

It is also necessary to compare its economics with drilling and blasting technique. Various factors contributes to the performance of tunnel boring machine separations –
–   Intact rock property like the tensile strength of the rock and uniaxial compressive strength.
–   Property of rock mass- in cases of foliated or bedded ground, direction of foliation guides the performance of tunnel boring machine separations.
–   Cutter geometry- cutter on the cutter head of the machine transmit the energy generated by the engine into the earth causing fragmentation. Thus it is important that the shape and angle of the cutter is adjusted so that adequate amount of energy is transferred and desirable penetration is attained in the ground.
–   Cutting geometry
–   Machine specifications
–   Voltage
–   Penetration and advancement rate
Performance of tunnel boring machine separation system can be calculated based on the voltage provided by the mine power distribution system. A basic computer load flow program is used to calculate the voltage.

Calculated voltage and measured voltages are then compared. Torque output is calculated with help this voltage input. Curve of speed horsepower versus current is drawn and compared to motor test data.

This results are then used to make adjustments in simplified motor model. With these information a torque verse distance curve can be made which will help to summarize the tunnel boring machine separations performance. By this way, the effects of the change in transformer taps, source of voltage, cable size and various other factors can be evaluated.

Penetration and advancement rates are essential to evaluate the performance of the TBM slurry separation system . Penetration rate is excavated distance during the excavation phase divided by the time. Advancement rate is the actual excavating distance to the total time which also accounts the total downtime of the machine maintenance, failure of the tunnel and machine breakdown.

Drillings rigs that are used onshore for mud separation processes has a vast number of components. Equipment connected to a rig is in some instances dependant on the type of rig but they in most cases have the same components. The drilling fluid being used during the mud separation process must be compatible with the formations being drilled

The shale shaker is the first phase of a solids control system on a drilling rig and they remove large cuttings from the drilling fluid, mud separation from fluids. A shale shaker is a primary mud separation tool on a drilling rig, they are considered tube very vital as all other equipment will be affected by the effectiveness of a shale shaker after it has cleaned and treated the drilling fluids.

AVN 2000 Mud Management System Replacement

Decanter centrifuge is also a major component on the mud separation system, its a device that helps separate the finest silt and sand from the drilling fluid. The centripetal acceleration on a centrifuge causes the substances and particles that are denser to move outwards in the radial direction. A mud tank is used for storing drilling fluid on a drilling rig, it also works as the base for the solids control equipment. Mud tanks are a vital component on a mud separation unit.

A desander and desilter are also for mud separation on oil rigs. They are a couple of hydrocyclones that deal with the separation of silt and sand from the drilling fluids found in drilling rigs. Desanders are usually located right on top of a mud tank and they will be followed by the degasser and the shale shakers . The vacuum degasser is also a necessary component on an oil based mud separation system, its purpose is the removal of gas from drilling fluids as this might cause the formation of bubbles.
