Real-time monitoring device for the stiffness of earth-rock and asphalt concrete dam materials during the rolling process

Abstract

The invention belongs to the field of earth rockfill dam construction quality control and provides a device for monitoring earth rockfill dam amterial and asphalt concrete core wall dam material compaction quality in real time. Via use of the device, assessment precision of compaction quality of dam materials being compacted can be improved, convenience of construction quality control can be improved when two dam materials coexist in asphalt core wall earth and rockfill dam construction processes, and construction quality of a high earth and rockfill dam can be ensured. Thus, a technical solution adopted in the invention is that the device for monitoring earth rockfill dam amterial and asphalt concrete core wall dam material compaction quality in real time comprises the following six parts: a dam material rigidity monitoring module, a positioning module, a controller unit, a power source module, an vehicle-mounted frequency hopping networking IP communication module and a far-end frequency hopping networking IP communication module. The device for monitoring earth rockfill and asphalt concrete dam material rigidity in real time in rolling processes is mainly applied to earth and rockfill dam construction quality control occasions.

Description

technical field [0001] The invention belongs to the field of construction quality control of earth-rock dams, and in particular relates to the real-time monitoring of the compaction quality (dam material stiffness) of earth-rock dam materials and asphalt concrete core wall dam materials in the vibration rolling process. Specifically, it relates to a real-time monitoring device for the stiffness of earth-rock and asphalt concrete dam materials during the rolling process. Background technique [0002] Effectively controlling the rolling quality of earth-rock dam materials and asphalt concrete core wall dam materials of high earth-rock dams is the key to ensure the quality of dam construction. According to the current construction codes for earth-rock dams, it is emphasized that "mainly control the rolling process, and test the compaction quality by random inspection" [1][2] . In order to overcome the fact that conventional earth-rock dam rolling quality control methods are g...

Problems solved by technology

However, due to the different material properties of roadbed materials, earth-rock dam materials, and asphalt concrete core wall dam materials, this index cannot be directly applied to these two dam materials; moreover, the device can only be used by vehicle-mounted drivers and cannot be used for engineering participation The remote control of all parties, so that the integrated control mode of "driver-contractor-supervisor-owner" suitable for China's national conditions cannot be realized
