Shanghai Jintai 11 SMC Engineering Drills Boost Dongying “Yellow Water East” Emergency Project

Shanghai Jintai SMC Engineering Drilling Rig once again plays a key role in the construction of a water conservancy impervious wall in Shandong. Eleven SC series hydraulic milling deep agitation rigs took the 25 km impervious wall construction of the “Yellow Water East” emergency project (Dongying Section) for sedimentation and storage projects. . This is another large-scale centralized application of the Shanghai Jintai SC series drilling rigs in the key project of water conservancy in Shandong Province after the Jilin Moon Bay Reservoir, Yanggu Chenji Reservoir, and Rizhao Groundwater Reservoir.

It is understood that the "Yellow Water East" emergency response project (Dongying Section) is an auxiliary project to provide water to the four cities of Weidong, Weifang, Qingdao, Yantai, Weihai and other Jiaodong Peninsula through the Guangnan Reservoir in Dongying City, and alleviate the water supply problem in these areas. According to statistics, Guangnan Reservoir is a large-scale plain reservoir mainly used for water supply from the Yellow River. The reservoir was built in October 1982, and has a capacity of 114 million cubic meters, which is 8 times the size of the West Lake in Hangzhou and has a Yellow River Delta. On the "Mediterranean" reputation.

In early September of this year, Shandong Water Conservancy Engineering Bureau Co., Ltd. took the lead in completing the construction of the SMC engineering impervious wall test at the second tender section, marking that the project entered the stage of major engineering construction. Through tests, the construction parameters such as the lap length of the wall, the water-cement ratio of the slurry, the volume of the slurry, the pressure of the air supply, and the speed of stirring and subsidence lifting were determined, which provided sufficient support for the follow-up of the large-scale construction of the SC double wheel deep drilling rig. Feasibility basis.

At the current 25-kilometer-long construction site, six construction units such as Shandong Water General, Jiangsu Jianji and Zhejiang Geotechnique have invested in 11 SMC drilling rigs. They have taken all the anti-seepage wall construction for the three tenders and covered the equipment. The main models of Shanghai Jintai SC series rigs include diesel crawler SC40, electro-hydraulic crawler SC45 and electro-hydraulic walking SC55.

Shanghai Jintai SC Hydraulic Milling Stirring Drilling Rig is not only suitable for water conservancy impervious wall construction, but also embodies unique process advantages in building foundation pit maintenance and water stop curtain. At present, Jintai SMC construction drilling rig has been able to carry out 60-meter ultra-deep and thick cement-soil mixing wall construction. Practice has proved that the SMC construction method has significant advantages that cannot be replaced by other construction methods in terms of construction efficiency, construction cost, and water stoppage effect.
