Real-time monitoring of construction quality for gravel piles based on Internet of Things

摘要

Application of gravel pile is a common foundation treatment method in civil engineering infrastructure constructions. The main purpose is to improve the foundation bearing capacity, reduce deformation and enhance the resistance to liquefaction. However, there are some problems in the traditional monitoring methods of gravel piles, such as irregular construction operation, unreliable process control, unscientific quality assessment and other issues. To meet the higher requirements of the construction quality monitoring for gravel piles, this paper researches and implements a construction quality monitoring system for gravel piles based on the Internet of Things technology, which is based on the analysis of control parameters for the construction quality of gravel piles. Field test results show that the system hardware has good earthquake resistance, data integrity, real-time performance and high reliability, with centimeter-level monitoring accuracy for pile point location and 0.1-m measurement error in pile depth. This technology can be used in the whole process monitoring of gravel pile construction and has a great significance of promoting traditional construction monitoring to advanced automated real-time process monitoring and management.
