A Study of the Technique for Assessment of Locations and Conditions of the Underground Pipeline: Case Study for Nakhon Pathom Province, Thailand

摘要

Underground pipeline systems in Thailand have been used for a long time. Lack of maintenances and longtime using cause a lot of damages. The water distribution systems are affected by the quality of water from contaminations and the quantity of water from leaking. As well as the sewer systems may flow through and contaminate the groundwater. Due to the long period of time of using underground pipeline systems, the verification of the underground location is need before testing the conditions of the systems with undisturbed area methods. This study focuses on the collection of the underground utilities locating methods and the conditions assessment methods. We also apply one suitable method for our case study area which is Nakhon Pathom province, Thailand. The results show the collection of methods to verify the underground location and conditions systems as well as the advantages and disadvantages of each method. Results also describe about conventional CCTV with push-rod camera for assessing underground pipeline systems for Nakhon Pathom province and the locations verification is fitted with ground penetrating radar, infrared thermography and acoustic location system. The design of a mobile robot to be flexible according to the pipe size and the creation of a computer program that can analyze the most suitable methods for examining buried pipes is a good option for further expansion in the future.
