Lateral liner wanted: fitted, no crease and tight

Fitting accuracy, flat surface and leaktightness: the latest IKT-Product-Test "Liners for Laterals" shows which liners fulfil the requirements of the network operators. The marks range from "VERY GOOD" to "POOR". Even the best liner, however, is not always free of malfunction.

Pipeline scanning: Novel technology for detection of voids and internal defects in non-conductive buried pipes

Non-conductive buried pipe systems deteriorate over time under the action of various applied and environmental loads, chemical and microbiological induced corrosions, and differential settlements. A key for effective infrastructure management practices is the availability of reliable and timely inspection data that serve as the basis for the selection of proper rehabilitation/replacement methods. CCTV inspection is limited to detection of visible defects on the inner wall of the pipe. Defects hidden beneath encrustation, cement mortar lining or a thermoplastic liner, as well as voids immediately outside of the pipe, are currently difficult if not impossible to detect. It is proposed to develop a novel inspection technology, employing ultra-wideband (UWB) pulsed radar system, for detecting “below surface” defects, corrosion, and out-of-pipe voids in non-metallic buried pipes. This paper presents the theoretical foundation for the proposed method, followed by the results of a detailed numerical simulation. The numerical simulation employed custom-developed finite difference time domain (FDTD) code using a cylindrical coordinate system. Results from simulating the scanning of selected soil-pipe interface scenarios are presented. Experimental validation efforts of the proposed pipe scanning approach are also described.

Large profiled plastic pipes: practical experience and test concepts

Besides the so-called classic materials concrete, reinforced concrete, vitrified clay and cast iron, plastic products are increasingly used for the construction, renewal and renovation of drains and sewers. Numerous surveys, research projects and product tests by the IKT - Institute for Underground Infrastructure (Gelsenkirchen, Germany) have dealt with the behaviour of single products under practical and laboratory conditions (cf. [1], [2], [3], [4]). Special emphasis was put on the rehabilitation of sewers, the investigation of special applications, the influence of quality as well as the determination of demands on the dimensioning and testing of pipes and construction methods.

The largest aircraft hangar in Europe is to be built in the south of the Frankfurt airport and completed by 2015. Up to four aircrafts of the type Airbus A380 will once be housed on a floor space of 49,000 square metres. The first half of the hangar is expected to be completed in 2008. A hangar of this size requires a sewage system which can be installed efficiently and which is permanently leakproof – despite high peak loads.
