Light in the dark -- a record of the night blockade of Harbin Jiaxing Railway Project Department of the second company of China Railway 23rd Bureau Group

There is a folk saying in the north that water freezes three points every day in winter. In Jiamusi in November, the temperature at night has dropped to - 10 ℃, mixed with cold wind, which makes people shivering just out of the autumn and not fully adapted to the cold winter. In such bad weather, the blockade construction for four consecutive days and seven hours a day is not a small test for the staff of Jiamusi station of Harbin Jiaxing Railway Project Department of the second company of China Railway 23rd bureau group to block the construction site

came into the scene, and the hot scene of fighting has lasted for four days. The night is like the day, shouting and shouting, and the sound is heard one after another. Although in the past four days, the cold wind and lack of sleep have made everyone tired from the continuous night blockade operation, but the passion in the eyes of the employees is not less. Seeing that the construction task has gradually ended, everyone is sincerely gratified and proud Since this year, hajia project has encountered unprecedented difficulties. At the beginning of the year, after receiving construction tasks such as platform 6 and platform 7 of Jiamusi station and ancillary works, the project was once in a deadlock. Due to the external environment and other reasons, it is very difficult to push forward. When the conditions are mature, the construction period will be delayed again and again due to the upsurge of heavy rain which has not been seen in decades. After the rainy season, the weather in Jiamusi gradually turned cool, and the effective construction period gradually shortened. The project department took a variety of ways to seize the construction period, gradually snatched back the time falling in the early stage, and achieved the blocking construction conditions according to the established scheme. The blockade construction is the most concentrated and longest continuous blockade operation since the project Department of Harbin Jiaxing railway put into construction this year. The task involves removing one transition line from platform 5 of Jiamusi station to the south station house side, building two arrival departure lines (line 13 and line 14), synchronously completing the platform walls, canopy, connecting passenger (luggage) underpass, line repair and other related supporting projects of platform 6 and platform 7, and also rebuilding the depot and retaining the access to the 545 special line, and moving the container yard to the East Jiamusi logistics base, among which It is necessary to pave 140 × turnout on the line between the new 140 × turnout and 144 × turnout, and the horizontal displacement of the pre paved turnout is 8m, accounting for the Tujia line, and 200m along the line longitudinal movement; the new 89 × turnout is pre paved on the existing 12 lines, and the horizontal movement of the turnout is 6m, accounting for the existing Xi Road, and the West longitudinal movement is 180m along the line; the new 87 × turnout is pre paved on the existing 12 lines, and the turnout is 275m to the West longitudinal movement, and 6.6m to the horizontal movement, which is arduous and difficult High degree, large amount of work

in order to ensure the smooth blockade construction and zero error completion of the task, the leading group of the project department should start from three aspects and do a good job in site planning. First, emergency preparation: an emergency response team was set up for the blocking construction, and the construction scheme of blocking and inserting turnouts in platform 6 and platform 7 project of Jiamusi station was formulated to lay a good foundation for the blocking; second, the up-down linkage was carried out to achieve "three in place, four guarantees", namely, safety guarantee in place, ideological workers in place, cold prevention and warmth preservation in place, organization guarantee, technical guarantee, logistics guarantee and material guarantee, Provide all-round guarantee for blocking operators. The third is to coordinate as a whole, carry out a hundred person mobilization meeting, and mobilize 2 excavators, 2 forklifts, 5 track longitudinal moving flat cars, 1 group of small tamping machines, 6 hoists, 8 groups of flexible shaft tamping machines, etc. From November 1 to November 4, the project department completed the blocking construction for four consecutive days, from 22 o'clock at night to 5 o'clock in the morning the next day. Under the adverse conditions, the workers standardized the five processes of the existing line breaking, removing rolling stone, inserting turnout, connecting line, line arrangement, line connection, and successfully completed the removal of transition convenience line, new line connection and platform 6 and platform 7 Established construction tasks such as supporting works have won time for follow-up work The blocking of

accelerated the closing progress of the project Department of Harbin Jiaxing railway this year, and ensured the completion of the new six or seven platforms project of Jiamusi station at the end of this month. After the opening, the passenger and freight pressure of Jiamusi station will be fully relieved, which will further guarantee the people's travel in Jiamusi city
