The invention discloses an automatic information collecting device during the rolling process of a corewall rock-fill dam, which comprises a GPS receiver, a wireless transmission unit DTU, an excitingforce monitoring VMU, a data base server and a power unit of a roller. The wireless transmission unit DTU is connected with the GPS receiver and is used for receiving and sending the signals sent bythe GPS receiver. The exciting force monitoring VMU is connected with rolling machinery and is used for sending and receiving the output signals of the roller. The database server is used for receiving the output signals of the wireless transmission unit DTU and the exciting force monitoring the VMU by the GPRS network. The power unit of the roller is used for providing power for the GPS receiver,the DTU wireless transmission unit and the exciting force monitoring the VMU. The GPS receiver is connected with GPS satellite aerials and difference wireless aerials, and is communicated with the wireless transmission unit DTU by RS-232. The GPS satellite aerials are arranged on the rolling machinery. The device is a real-time information collecting device with high precision and full automationduring the filling and rolling, which realizes the GPRS distant real-time transmission of dynamic data. The device also has the advantage of good stability of data transmission, thus providing conditions for the all-weather distant real-time monitoring of the dam rolling quality.
Description
technical field [0001] The invention relates to a construction quality information collection device for a core rockfill dam. In particular, it relates to a high-precision, fully automatic core rockfill dam rolling process information automatic collection device that provides conditions for all-weather real-time monitoring of the filling and rolling process of the core rockfill dam. Background technique [0002] During the construction of core rockfill dams, effectively controlling the rolling compaction of dam materials is the key to ensure the quality of dam construction. According to the "Code for Construction of Roller-Compacted Earth-rockfill Dams" (DL / T 5129-2001), the rolling quality of core rockfill dams mainly depends on the compaction parameters during the construction process (layer thickness, soil and stone properties, rolling times, rolling speed, exciting force, etc.) and compaction standards (sampling test results for unit acceptance, such as compaction or dr...
