Pipe statics

The special design of the pipe’s wall and the material used, namely high density polyethylene (HDPE), ensure a balanced ratio of ring stiffness on the one hand and ring flexibility on the other. Regular static calculations prove its suitability for common traffic loads in installation depths ranging from 0.5 to
6.0 meters. In addition to that, GIGAPIPE SYSTEMS has numerous references for special applications, such as heavyload traffic, loads from airplanes, in the field of groundwater or due to rail tracks. For example, GIGAPIPE is the ideal solution for high dynamic loads and thin covers of only 1.0 m (e.g. airstrip of an airport). Moreover, it also proves its suitability with thick covers of more than 6 m. Upon request, GIGAPIPE SYSTEMS works out your individual, project-related static calculations.

Fields of Application:

  • Waste water networks, rain water systems
  • Combined sewers
  • Drainage systems for premises
  • Special solutions for industry and communities
  • Special constructions

Flexibility

flexibility

The flexibility of the GIGACOR system ensures that the pipes remain flexible under variable loads and soil movements and transmit the load stress in the longitudinal and cross-section to the surrounding soil by deformation. The relaxation behavior of the applied polymer guarantees that the tension resulting from long-lasting system deformation is almost fully reversed. Short-term deformations are completely reversible anyhow.

RIGID PIPES

All loads (both static and dynamic loads) are born by the pipe. In case of failure,the material cracks or breaks.

FLEXIBLE PIPES

All loads are born by the soil surrounding the pipe; the pipe is free of tension.

Abrasion resistance

abrassion

In order to test the resistance of pipes to mechanical wear, the so-called Darmstadt method is used. Comparative tests show that plastic pipes, in particular pipes made of polyethylene and polypropylene offer the best abrasion resistance of all pipes. The layout of the GIGACOR’s doublewall structure allows to achieve maximum material efficiency and weight reductions while keeping longevity in mind.

Hydraulic systems

The drainage behavior in gravity lines is mainly determined by the pipe’s decline and the surface quality of the pipe bottom. Thanks to the optimum processing of the raw material, the GIGACOR offers a non-porous, very smooth inner pipe with an absolute roughness of the pipe wall of 0.005 to 0.05mm. Such a surface prevents the formation of deposits, incrustations andthus the biochemical processes related to them. In addition to that, it transports the effluent even at minimal sewer declines.Due to the low coefficients from the field of fluid engineering,

Results of a simulated installation with a 92% and 99% soil compression (Proctor standard), calculated by means of the “finite element method”: with increasing soil compression due to dynamic loads, the maximum soil tension is not in the pipe’s soffit area, but at the impost. Here, GIGAPIPE pipes absorb the load stress, supported by the highly compressed soil.

the influence of pipe connections, branches, shafts, etc. has to be taken into consideration when calculating the mathematical service roughness (kb) (please find more detailed information in specification sheet ATV-DVWK-A 110 “Hydraulic Dimensioning and Performance Verification of Sewers and Drains”). The diagram shows the GIGACOR throughputs for a roughness value of k = 0.25 mm.
