All property owners come to a point where they need to install or replace their drain or water main pipes – projects that require traditionally extensive digging. This can be disruptive and expensive. Trenchless technologies allow renewing of the water pipe network without the conventional digging of inconvenient trenches. There are a few traditional trenchless methods developed like horizontal directional drilling, pipe bursting as well as state-of-the-art new trenchless technologies including cured-in-place pipe lining. A trenchless technology new water pipe can provide cost-effective solutions for the renewal of the main water pipe.
Contractors specialized in trenchless technology offer services of comprehensive coverage of renewal, replacement, and pipe installation using trenchless technology methods. They implement efficient design and construction processes that save time and money. A state-of-the-art water project management system based on trenchless technology can be an efficient solution for city main water pipe networks as well as localized residential projects. This cutting-edge engineering technology allows optimal project delivery timing, as well as safety and quality assurance.
Applications of the Trenchless Technology
Trenchless technology has applications in different areas, each of them being based on some specific construction methods:
- Trenchless construction – this includes such construction methods as horizontal drilling, micro tunneling, tunneling, pipe jacking, pipe ramming, horizontal auger boring, moiling, and other methods for the installation of cables and pipelines below the ground by using only minimal excavation. The main difference between traditional subsurface construction techniques and trenchless subsurface construction depends upon the size of the passage under construction. Trenchless construction requires taking in consideration the loads applied to surface and soil characteristics.
- Trenchless rehabilitation – includes such construction methods as thermoformed, shotcrete, pipe-slip-lining, gunite, pipe bursting, grout-in-place pipe, cured-in-place pipe, mechanical spot repair, and other methods for the replacement, rehabilitation, or repair with minimal excavation of existing buried pipes and structures. If damaged pipelines require reinstatement of structural integrity it is applied mechanical spot repair. Thermoformed pipe lining is slip-lining, and cured-in-place pipe involve pulling a new liner into an existing pipe, then forcing the liner to expand and fill the pipe by applying heat or pressure. Cured-in-place pipe technologies combine a carrier made of fiberglass impregnated with ambient curable resin, ultraviolet light, or heat to form a “pipe within a pipe”. Trenchless rehabilitation methods are more cost-effective than traditional digging and replace methods.
A trenchless technology new water pipe requires only subsurface construction work with no continuous tranches or just a few trenches. Trenchless technology is a rapidly growing sector of the civil engineering and construction industry. It is based on a family of materials, methods, and equipment used for rehabilitation, replacement or the installation of new underground infrastructure with minimal disruption to surface business, traffic, and other activities.
Private clients may call professional contractors specialized in trenchless technology in order to benefit of a comprehensive approach and the experience of a solid team of engineers, architects, planners, and technicians. Trenchless technology is not only used in the water industry but it is also especially useful for clients in the fields of infrastructure, transportation, environmental, energy, and buildings.
