GPR application in Civil Engineering to search and detect underground Networks

Abstract

The industrial development and the intensive use of urban space lead to several problems in the management and operation of public services such as drinking water networks, sewer, telephone, gas, electricity, street lighting, and various cables and pipes that are buried either at footpaths or roadways. Damage or malfunction of pre-existing public services can potentially cause danger to humans. In order to minimize risks, GPR profiling was constructed as a tool of advanced non-destructive technologies leading to practical solutions to detect buried networks and reduce problems related to the destruction of existing underground utilities. The main objective of this study is to search and identify the various hidden systems to map them and indicate them on-site to avoid possible incidents. The purpose of this operation is to produce GPR profiles on the surface to be examined, while respecting a fairly regular spacing between patterns, using non-destructive techniques such as the GPR and the radio detector.

Ground Penetrating Radar Data Acquisition to Detect Imbalances and Underground Pipes

“…The information improves and updates public service placement plans and serves as a basis for urban planning. This paper complements the work already published in [7].…”

“…La résolution horizontale Rh de chaque antenne, en fonction d'une distance de 30 cm entre la surface du réflecteur et l'antenne, et la résolution vertical Rv peuvent être estimées comme suit. The horizontal resolution Rh for each antenna based on a distance of 30 cm between the reflector surface and the antenna and the vertical resolution Rv can be estimated as follows [7,[17][18][19]…”

“…There are several non-destructive methods of detection, such as acoustic detection, electromagnetic induction and GPR [2], which locate underground targets such as buried cables and pipes and monitor water leaks [3][4][5][6][7]. The GPR method is used in many areas of civil engineering and has advantages, including its speed of application, low cost, security, anti-interference, and lack of destruction [8,9].…”

Numerical modelling of bridge deck reinforcement corrosion based on analysis of GPR data

“…While some studies have reviewed the general application of GPR in civil engineering [3,4] or focused on on-site inspections for specific constructions [5], there is still a notable lack of comprehensive critical evaluation of GPR's effectiveness in corrosion assessment for reinforced concrete. GPR has demonstrated its utility in detecting buried networks and examining reinforced concrete structures, thanks to its improved vertical resolution and strong signal reflection from high conductivity bars [6][7][8]. The authors' objective is to gain deeper insights into the capabilities and limitations of GPR in detecting and quantifying reinforcement corrosion, aiming to enhance corrosion assessment practices in civil engineering structures.…”

A Novel Approach of Designing Insubstantial AVA operating in UWB for GPR Applications

“…Ultra wide band technology is on more demand now a day due to its attractive features. The applications of UWB include GPR, military, microwave imaging, radars etc due to its huge capacity, powerful penetration and accuracy [20]- [22], [34]- [36].In GPR system antenna frequency is one of the prominent factors which decide the performance of the system.GPR system comprises 3 components radar gram, antenna and power supply. The control unit or radar gram emits electromagnetic radiation in to the surface of investigation, the reflected signal is collected by the antenna and display results on screen which helps GPR operator to determine results accurately.…”
