Tunneling refers to a range of activities and processes involving the use of airless pumps inside tunnels or galleries. It is crucial to emphasise that airless pumps are widely used in various construction applications, and specialised mono- or bi-component versions are often used in injections directly associated with tunnelling. In this article, we will examine the main applications of airless pumps in tunnelling.
Sealing Cracks: In the context of tunnel or tunnel construction, they are essential tools for sealing cracks or fissures in tunnel walls. This process involves the injection of sealing materials, such as resin or mortar injection, into the cracks in order to prevent water infiltration and wall failure.
Dust Control: Airless pumps are also used for the application of coatings or dust control materials inside tunnels or galleries. This improves air quality and worker safety.
Drainage with Airless Pumps: In some situations, airless or AODDP (Air-Operated Double Diaphragm Pump) pumps can be used for draining water inside tunnels or galleries. This allows excess water to be pumped outside, preventing flooding and ensuring a safe working environment.
Tunnel Interior Coating: Airless pumps are ideal for applying protective coatings or paints inside tunnels, thus protecting underground structures from adverse environmental conditions and corrosion.
In general, airless pumps are devices that provide high pressure for the application of various materials on surfaces or for deep injection. This versatile approach is used in a variety of construction contexts, including those related to tunnelling. However, the specific methods of use and objectives will vary according to project needs and site conditions.
It is crucial to emphasise that tunnelling is a highly specialised area of construction, requiring specific skills and specialised equipment to ensure the safety and effectiveness of underground excavation and construction operations. Thanks to its extensive experience and know-how, WIT is positioned as an industry leader for injections in the field of tunnelling and beyond.
