An Analysis of Factors affecting the damage of irrigation buildings in the form of drainage pipes. case study of Phraya Banlue water Transmission and Maintenance

Abstract

The research titled " An analysis of factors affecting the damage of irrigation buildings in the form of drainage pipes. Case Study of Phraya Banlue Water Transmission and Maintenance" aims to study the factors causing damage to irrigation structures, propose maintenance solutions, and estimate the repair and maintenance budget. The research process began with a review of relevant information, followed by data collection using a check sheet based on the Walk Thru system in areas where damage to 27 drainage pipe structures was observed. The causes of the damage were analyzed using the Why-Why Analysis method to identify the root causes of the problems and to propose appropriate maintenance approaches along with a suitable budget. The experimental results revealed that the most significant factor was corrosion due to rust, accounting for 31.91%, while cavities were identified as causing the most severe damage at 13.83%. Positions A and B of the drainage gate were the most affected areas, as exposure to both water and air led to oxidation reactions. A six-month maintenance plan was proposed, along with a preventive maintenance strategy. The proposed budget for the repair and installation of a new drainage gate was estimated at 66,141 THB per gate, aiming for the most cost-effective and efficient use of resources.
