the Beijing East trunk canal project is the underground water transmission project with the longest route and the largest investment among the supporting projects of the Beijing South-to-North Water Transfer Project, with a total planned investment of 9.17 billion yuan. A few days ago, a message came from the site of the East Main Canal Project of the South-to-North Water Transfer Project: Shanghai Jintai 15 sets of SG series hydraulic grab with "green robes" led the battle in 13 bid sections, once again depicting a bright "Jintai color" on this century project line. This will eventually realize the economical and commercial production of 15 grabs, covering five mainstream models such as sg40a, sg40e, sg46, sg50, sg60, etc

it is understood that there are 13 bid sections in dongganqu, with great stratigraphic differences, including clayey silt, silty clay, sandy soil, round gravel, pebble layer, etc., and the maximum particle size of gravel and pebble is 100mm. The complex geological conditions provide sufficient space for various types of grab in Shanghai Jintai. A sg50 constructed for China Gezhouba Group Co., Ltd. in the third bid section has worked for nearly 5000 hours, but it is still young and strong, and the 1.200m*36m trough can be completed in 20 hours; In the sixth bid section constructed by China Railway fourth Bureau Group Co., Ltd., the geology below 30 meters is dominated by fine silt, and the efficiency of sg60 grabbing a 1.200m*38.5m groove is between hours...

SG grab plays a "leading role" in the South-to-North Water Transfer Project. Whether the whole device is reliable is by no means the first time: as early as during the Han River Junction Project on the middle line, 32 Jintai grab buckets have undertaken the construction task of seepage prevention of 250000 cubic meters of cofferdam, accounting for 95% of the total work volume. The spectacular scene has amazed the industry; All the problems in China in Yuzhou are related to each other. Most of the Changge section is expansive soil layer. In order to overcome the worldwide problem of expansive soil open channel slope treatment, the construction unit specially selected Jintai Hall displacement sensor, which has small inertia, high frequency response, reliable operation and long service life. SG series grab buckets are directly grabbed into square grooves. After adopting slurry wall protection, the reinforcement cage is hoisted into the well at one time, Then, the concrete is poured into piles by the underwater vertical tremie method, which has achieved innovative results in this bid section
