On October 21, after the construction unit and the railway transportation department worked closely together, the first three-level railway blockade construction of the TJ-6 standard of the Jilin section of the Shenyang-Baihe high-speed railway was successfully completed, and a safety barrier was built to ensure the operation of the railway.
The No. 1 Bridge of Tanghe, 6 BiaoTanghe, Jilin Section of Shenbai High-speed Railway, undertaken by China Railway 23rd Bureau Group, spans the Hunbai Railway, of which No. 0 abutment is located on the existing mountain mass on the left side of the railway, and the abutment is 17 meters from the center of the line and 12 meters from the height difference from the line. Pier No. 1 is located on the slope of the existing railway subgrade, only 12 meters from the horizontal distance of the line center, and half of the bridge platform invades the tang riverbed. In order to ensure the safety of the operation of the Hunbai Railway during the construction of the bridge, the construction unit carried out the construction of three-level line blockade construction ranging from 3 to 7 hours a day at the 88km950--89km150 between Yonghong Station and Xianrenqiao Station of The Hunbai Railway for four consecutive days.
The third division of the Shenbai high-speed rail project department of the China Railway 23rd Bureau Group, which undertook the construction task, did a good job in the on-site investigation in advance and formulated a detailed construction organization plan and emergency plan. All employees were re-educated, retrained and simulated in key processes on both wired construction safety knowledge. The construction machinery and machinery were comprehensively overhauled and maintained, the construction materials were put in place in advance, and the lean construction team and on-site protection personnel and station liaison officers were mobilized, and the responsibility was clearly implemented to the post. During the construction of the blockade, the project department and branch supervisors and professional management personnel followed the shift to supervise and control the construction safety. The hard isolation installation of the No. 0 abutment requires the 2.5-meter-long steel pipe to be embedded in the ground for 0.7 meters, and then the 1-meter-spacing pipe column is welded with scissor brace and horizontal bracing, and then the steel wire mesh is laid. The construction site has steep slopes and hidden dangers in high-altitude operations, and the staff participating in the war strictly implement standardized operations without deviation, strictly manage the site and control the construction process, and implement one machine and one person protection for large machinery and equipment to ensure that safety is foolproof. After the implementation of hard separation of the line, it will effectively prevent the construction of the abutment from disturbing the threat posed by the mountain to the traffic, and build a safety barrier.
With the cooperation of the Tonghua Depot, the Engineering Section and the Jilin Power Supply Section of China Railway Shenyang Bureau Group Corporation, 22 steel pipe piles have been installed, 21 meters of isolation fences have been installed, 600 square meters of the original ground clearance, and 120 meters of construction roads have been filled, achieving the first three-level line blockade construction.
