Tunnel Isolation Feature

Tunnel isolation is one of the best methods for not penetring water into the tunnel. Water penetration can lead to deterioration and substantialness. Damage to structural and functional components, especially in transportation tunnels, should be considered. Injury prevention, interception and collection of leaks are necessary. There are five general ways to control the penetration of water into the tunnels as follows. Tunnel isolation method can be unique.

Site selection for tunnel isolation

Choosing a site for your long tunnel depends on a number of factors. of the factors, and the lowest of them is the angle of the sun. You want to maximize the amount of sunlight. At the same time, many say you have to manage the upper level of the tunnel. The tunnel so that the end wall is faced with winter winds. That in some areas of Alaska, the two are not the same. Tunnel builders, however, suggest that the structure needs to be orientationd to get the most results in tunnel isolation.

Often in conventional tunnel coatings, two or more of these methods are used in the construction of the same coating. Even after construction, therapeutic measures such as geomembrane injections, may be taken for excessive control. Leakage of unusable membranes along with conventional tunnel cover is very high pressure.

The superiority of austria's new tunneling method for tunnel isolation

It requires the precise work of the new Austrian Tunneling Method (NATM). It was successfully used around the world in the construction of transport tunnels. The new Austrian tunneling method in tunnel isolation is a method by which rocks or soil builders around the tunnel are integrated. The overall loop-like support structure, and therefore is constructively part of the support system. An integral part of the new Austrian tunneling method in tunnel isolation is the combination of highly technical sealing and drainage system composed of the most advanced geosynthetic art in tunnel isolation.

Tunnel isolation and geosynthetic system

The geosynthetic system in tunnel isolation should provide waterproof integration. The life of the tunnel and therefore must withstand a different. Different types of stress and pressure, both during and after installation of construction as well as variable and harsh chemical environments have a significant impact on tunnel isolation. Sealing of plastic geomembrane sheet with a non-woven protective geotextile drainage layer, the dominant system is used in conventional sealing methods such as asphalt membrane or glass fiber reinforced with spray of plastic or bitumen-latex products worldwide in tunnel isolation.

 

Meet tunnel isolation needs with new Austrian tunneling method

The developed geosynthetic system meets the needs for the new Austrian tunneling method. Not only does it have fast tunneling rates and a new Austrian tunneling method, but it also has a tough construction. The need for optimal waterproofness and a new Austrian tunneling method places high technical demands on the system, in which protecting loosely placed geomeberg is of particular importance.

Components of the new Austrian tunneling and tunnel isolation method system

The basic components of the system are the new Austrian tunneling method, stone. Or plant surface, non-woven geotextile, fastening system,ummbran and concrete casting of the final geomembrane procedure which plays a special role in tunnel isolation.

Suitable surface area for tunnel isolation

Not-so-solid geomembrane placement is necessary for tunnel isolation. A concrete layer with a thickness of at least 40 mm is essential for the backup so that it can be used as an attachment to the pegs of the adhesive sheets. The maximum grinding size should not exceed 16 mm and usually should not be used from crushed stone. Dorsal surface conditions are of particular importance at the time of concrete. Since the installation of geomembrane sheets, this issue should be considered. Sheets must be firmly bonded against the beam without high pulse and pressure. To achieve this goal, it should be used to smooth the excavation surface and cover any metal surface. In addition to a flat surface on excavation, recent research suggests that the rock surface should be covered immediately after excavation so that geomembrane can be used with higher pressure in tunnel isolation. It is possible to gradually add to the pressure of the geomembrane layer to complete the tunnel isolation.

Tunnel Shading and Isolation

Shade plays an important role in site selection and tunnel isolation due to its important role. The amount of light limits your long vision in the tunnel. The rule of crowding is that tall tunnels must be built in one place. Double distance from the barrier height of that barrier for example, if two elevated tunnels are built next to each other. And each long tunnel is 12 feet high, then the long tunnel must be at least 24 feet away. The same is true of other barriers, such as trees.

Uncomperned geotextile not only performs protective function but also tunnel isolation.

Uncompoled Geotextile and Tunnel Isolation

Uncompoled geotextile not only performs protective function but also tunnel isolation and is therefore decisive. The importance for the effectiveness of the sealing system is determined. The technical demands for uncompoled geotextile in tunneling are the result of a variety of stress and strain along the way and tunnel isolation. The construction phase is also specified in terms of use.

Soil Drainage and Tunnel Isolation

Try not to place your long tunnel where the water is close to it. the surface, where you have an impenetrable soil layer, or where other factors may cause water to penetrate into the tunnel.

 

Site selection and tunnel isolation

One feature of a long tunnel is that it is long enough in the middle of the line to drive a tractor in (albeit smaller). Long tunnels are designed to be available, so take advantage of this. Find them where you can't easily get in and out.
