Description

Real-time monitoring method for filling/pouring and rolling construction quality of dams in narrow and deep valleys

technical field

The invention relates to a real-time monitoring of the construction quality of filling (pouring) and rolling of dams in water conservancy and hydropower projects. In particular, it relates to a method for real-time monitoring of filling/pouring rolling construction quality of narrow and deep valley dams.

Background technique

With the development of dam construction technology, 200m or even 300m high earth-rock dam projects and roller compacted concrete dam projects have emerged one after another. The emergence of high dams puts forward higher requirements for the construction quality control of dam filling (pouring). The traditional quality control methods of dam filling (pouring) include supervision of side stations, test pit inspection and nuclear density instrument inspection, etc. These traditional methods rely on human labor, are inefficient, and are easily affected by human factors. On the other hand, Test pit inspection and nuclear density meter inspection belong to on-site sampling inspection, which cannot truly reflect the compaction quality of the entire rolling chamber surface, and may easily cause quality defects that are difficult to be found and irreparable. Therefore, relying on traditional monitoring methods has been unable to meet the increasing quality control requirements of high dam construction.

The dam roller compaction construction quality monitoring system has undergone a series of innovations and improvements in the construction process from initial exploration and application to successful application in the construction of Nuozhadu core rockfill dam, Longkou RCC dam and other domestic high dams. Real-time monitoring, analysis and result display of construction parameters such as the number of rolling passes, compaction thickness, rolling speed, and state of exciting force have been realized, thus realizing the refined and all-weather real-time monitoring of the dam rolling construction process. Monitoring and management makes up for the shortcomings of traditional dam filling (pouring) construction quality control methods, and greatly improves the quality control and management level of dam rolling construction. It is the general trend to introduce the dam rolling construction quality monitoring system to strengthen the quality control of dam rolling construction during the construction of high earth-rock dams and high roller compacted concrete dams. Dams and high roller compacted concrete dams often encounter the situation that the GNSS positioning accuracy cannot meet the demand and there is no operator 2G/3G network coverage, resulting in dams that only use GNSS positioning and use the operator 2G/3G network for data transmission. The rolling construction quality monitoring system has been unable to meet the needs of rolling construction quality monitoring of high earth-rock dams or high roller compacted concrete dams in narrow and deep river valleys. Therefore, adopting the positioning compensation technology of the intelligent total station to compensate the GNSS positioning, and building the wireless network in the ZIGBEE dam area for data transmission will ensure the normal operation of the real-time monitoring system for the quality of the dam filling (pouring) rolling construction and improve the quality of the dam rolling. It is of great significance to improve the level of construction quality management.

At present, the research on the application of intelligent total stations mainly involves deformation observation (Yuan Tianqi, Zhang Bing. Current status and development trend of dam external deformation monitoring technology [J]. Hydropower, 2003,29(6):52-55), control Measurement (Wei Jianfei.

Water Conservancy and Hydropower Technology, 2007,38(12):62-65) and thickness detection (Wang Gang, Shi Baojie, Li Hong. Application of Total Station in Tunnel Shotcrete Thickness Detection[ J]. Water Conservancy and Hydropower Technology, 2009, 40(6): 80-82) and other static measurements, did not involve the research on the continuous measurement of the spatial position of dynamic construction machinery by intelligent total stations, and the application of intelligent total stations to large Research on real-time monitoring of dam rolling construction quality has not been reported. In the past, data transmission in the real-time monitoring of dam rolling construction quality mostly used the operator's 2G/3G network, and there is no report on data transmission through the construction of ZIGBEE wireless communication network in the dam area.
