Recently, a Sany STR130-5 double drum roller was involved in the roller compaction test of the concrete dam of Dazhuman Reservoir in Longli County, Guizhou Province. After the construction and the staff of the Sany team, the first test was a complete success. The Sany Double Steel Wheel was highly praised by the project's chief engineer and excitedly praised it as "the ultimate compactor for compacted concrete dams." “Crushing concrete dam†is a new type of dam that applies earth-rock dam rolling equipment and technology to concrete dam construction. It uses super-dry concrete to be paved and crushed layer by layer to form concrete dam. The project is mainly concentrated in the southwestern part of China. The construction of the Damuman Reservoir dam was the first to undertake the RCC dam project. Because there was no previous construction experience of similar projects, the construction process of the RCC dam was not well understood, so they specially dragged the equipment to the site in advance. experimenting. Since the construction is officially started in the future, the time of the pilot phase is very tight and must be completed before the year. Due to the less experience in the construction of RCC dams in China and the lack of complete and mature construction techniques, in order to help the construction party to successfully complete the test, Sany Heavy Industry specially dispatched the staff of the Road Machinery Research Institute and the manufacturing department to Guizhou to provide technical support. After arriving at the construction site, the Sany staff first made a professional measurement of the amplitude and vibration acceleration of the roller, and determined that the equipment excitation force met the requirements. The lack of compaction in the previous test section was mainly due to the incorrect construction method. To this end, Sany R & D and manufacturing personnel accompanied the construction party to the nearby RCC dam, carefully studied the material ratio and the rolling method, and invited an operator who had experience in the construction of such projects to cooperate. After perfecting the construction process and correcting the operation method, if the Sany STR130-5 double drum pressure road has the help of God, the concrete dam compaction degree is as high as 101.43%, the virtual pavement thickness is 35 cm, and the compaction thickness is 30 cm. The construction party is very satisfied, indicating that the project will continue to purchase multiple Sany road rollers for the crushing of concrete dams after the start of the project. The successful trial of the Sany double-steel roller in Dazhumang Reservoir has set a new benchmark for the construction of RCC dams in China, filling the blank of construction methods of similar projects in China, and laying the equipment and method of Sany Road Roller in the industry. The leading position is of great significance.
