The demand for environmentally friendly and advanced trenchless technologies is growing every year with potential new applications across the field of infrastructure development. Emerging and high-growth markets like district heating, telecommunication networks, underground power cables, solar power, and charging infrastructure for e-mobility all require smart solutions that can be delivered with minimal disturbance to society and the environment.
PERFORATOR`s TAIFUN series is proven to be highly versatile when it comes to the trenchless laying of service pipes and the longitudinal installation of all types of underground pipes. The compact design is suitable for all inner-city applications as well as crossings in transport infrastructure, such as roads or railway lines.
There are various possible applications within the growing range of tasks in infrastructure development such as supply networks for gas and water pipes, sewage and rainwater drainage systems, drainage networks and flood relief systems, district and local heating networks, telecommunications networks (FTTH and FTTX), underground cables (high- to low-voltage grids), connections in solar and wind farms, charging infrastructure for e-mobility, and geotechnical applications in tunnelling and well construction, as well as special mining applications.
In addition to the wide range of applications, the TAIFUN series can also be used for a variety of trenchless drilling methods.
Horizontal pressing with expansion part
Whether unguided or guided, the impact drill rig can be used to lay pipes with a diameter of up to 160mm in displaceable soils over a length of up to 50m. During percussive boring, the rod is pressed into the ground as far as the target range while the soil is displaced, and the product pipe is pulled in with it during retraction. In the guided version, walk-over positioning technology is used for directional control.
Horizontal auger boring method
The drilling equipment is used to drill uncased boreholes with a diameter of up to 280mm and over a length of up to 25m. The augers must be fitted with a supporting edge for this purpose. After drilling, the product pipe is pushed or pulled in. For cased boreholes, a casing pipe remaining in the soil or a recoverable casing pipe is installed at the same time as the augers. The casing pipes are then pushed out with the carrier pipes and reused. The auger boring method is also suitable for DTH percussive drilling in unconsolidated and solid rock.
Horizontal directional drilling (HDD)
Directional drilling equipment enables pipes of up to 280mm in diameter and 100m in length to be laid using the HDD method. The system is controlled using walk-over locating technology. After the pilot bore, the expansion bore is carried out using a backreamer and the product pipe is pulled in.
Pilot pipe jacking with soil displacement (Taifun 15 only)
In the first step of this method, a pilot pipe string is jacked by displacement. The position is measured using an optical-electronic navigation system (OEN). Directional corrections are generated via a pilot drill head with a control surface. In the second step, a casing pipe (or, alternatively, a recoverable casing pipe) is then installed and the pilot pipe is pushed out at the same time. In the third step, carrier pipes can be pushed or pulled in.
Special applications are also possible. “Berlin” construction method from circular shafts as well as the use of collectors with an internal diameter ≥ 1250 mm for the subsequent construction of service pipes or surface drainage systems.
The TAIFUN series stands out above all thanks to its versatile range of applications and processes, while also offering significant advantages:
- Reduces investment in different machine types.
- Less maintenance and repair work than with multiple machines, no need for multiple inspections for accident prevention regulations.
- Minimises the amount of training required for the drilling crew. Frequent use prevents application errors. Only one transport concept required.
- The hydraulic station is not required for use with mini excavators (required performance must be guaranteed).
- Simple operating concept via hydraulic control block; the TAIFUN 15 even offers this with radio remote control.
- Quick and easy conversion between the various drilling variants.
- Front and rear supports ensure that the machines are optimally aligned; the TAIFUN 15 even has the option of hydraulic alignment.
- The rack and pinion ensures fast, continuously variable movement of the drill carriage within the jacking frame.
- Direct-drive rotary motors ensure steady torque delivery and high rotational performance. The TAIFUN 15 has a two-stage rotary drive with up to 160 rpm at 1000 Nm, or 60 rpm at 3100 Nm.
Innovative, high performance, very compact and for universal use – the TAIFUN series from PERFORATOR sets new standards.
