Demonstration of the mini jacking machine with the MMP-35 controlled head

During the demonstration, specialists will show the speed of the jacking machine, the possibility of changing the direction of the jacking or sinking, perform an automatic drilling profile for final documentation and a 2×110 mm double-pipe jacking of 20-30 m.

Renovation of sewer systems using polymer concrete elements

The demonstration will show polymer concrete elements used in trenchless renovation of canals, round and rectangular concrete manholes and the crown of settling tank raceways. Issues concerning the technical parameters of polymer concrete, the method of joining the elements inside the canal or manhole and recommended epoxy adhesives and injection mortars will be discussed. The show will also include information on the current and future portfolio of vitrified clay drill pipes used in trenchless sewer network construction and rehabilitation.

Demonstration of the capabilities of Hovering Solutions’ autonomous flying robots for sewer network inspection

The demonstration will showcase the capabilities of Hovering Solutions’ drones performing sewer network inspections. The robots operate without remote control, radio communication, GPS/GNSS or lighting. The drones capture high-quality data, including 3D georeferenced point clouds, high-resolution panoramic images and a comprehensive damage report. This data facilitates a comprehensive assessment of tunnel condition, cross sections and tracking changes over time. Hovering Solutions provides a web-based 3D visualisation platform for easy access to the data and its analysis.

Measuring the tightness of gravity sewage systems using the air method in accordance with the PN 1610 standard

During the show, the process of measuring sewage tightness will be presented. The measurement will take place in accordance with the requirements of the PN 1610 standard and will be carried out using air. Proprietary equipment will be used to record the process.

Complete revitalisation of gravity sewers with Concept PP-HM pipes up to DN560

GroundTEM – demonstration of non-invasive measurements using the Time-Domain Electromagnetic Method (TEM)

The measurement system consists of a transmitting and receiving system. Measurements are based on the induction of an electromagnetic field deep into the Earth using an induction loop. When electromagnetic waves encounter different geological layers, eddy currents are generated, which in turn cause a secondary electromagnetic field. The electrical conductivity of the soils and rocks studied is controlled by mineralogy, clay content, water content, salinity and porosity. These waves are then recorded at the surface using a receiver loop. From the resulting logs, the conductivity distribution of the geological medium can be calculated.
The TEM method helps to locate groundwater in particular, monitor the state of the aquifer, and distinguish between different geological deposits.
The demonstration will show how the measurement is carried out – from laying out the measurement system to obtaining the final result from a given measurement point.

Structural testing of sewer network facilities in practice. On site and in the laboratory

The following tests will be presented and discussed during the demonstration:
– pull-off (requirements of EN-PN 1542 for the reality of construction)
– GWT
– detection of reinforcement
– measuring the thickness of the surfacing, laminate, coating
– Schmidt hammer
When recognising the technical condition, both during ongoing inspection and during a more detailed assessment related to e.g. expert opinion or design, it is necessary to carry out tests on the structure and its working environment. Some tests are also later part of the acceptance tests after the renovation work has been carried out. Some of the tests are so simple that they can be carried out and the results obtained on site. What is important, however, is to what extent the field conditions influence the correctness of the pull-off test or Schmidt hammer number test, for example, and whether they comply with the requirements of the standards to which they refer. Some of the tests can only be carried out in the laboratory, e.g. testing the compressive strength of concrete or linings, assessment of sulphate contamination or verification of materials by infrared spectra. For these tests, it is crucial to take a representative sample on site.
During the show, the discussion of the above issues will be combined with a live demonstration of field tests, such as the pull-off test, Schmidt hammer, GWT waterproofing test, pH tests, reinforcement detection, resin coating thickness measurement. Specialists will also discuss the interpretation of test results in the context of determining ‘compliance with requirements’ of, for example, completed works.
