On November 25, the last piece of T girder landed in the predetermined position of Taipinggou Bridge, and at this point, the 495 T girder erection task of the Xingxian Beishan Transit Highway Project undertaken by The Taiyuan Company of China Railway Sixth Bureau was successfully completed.
▲ Taipinggou Bridge was successfully erected
Xingxian Beishan Transit Highway Project is located in Xingxian County, Lüliang City, the project starts in the east of Xingxian County, follows the Provincial Highway Xinhei Line (S313), runs along the Beishan from east to west, passes through the Jingxing Expressway, passes through nineteen villages in two townships and one town, and ends at the Yaozeyagou Bridge in Caijiaya Township, and connects with the Beipo Village of Caijiaya Township in Xingxing County, with a total length of 15.3 kilometers. The lot includes a total of 13 bridges, 46 culverts and 12 km of roadbed.
Since March 22, 2021, Taiyuan Company of China Railway Sixth Bureau has officially launched the operation of the whole line of girders. In order to ensure that the girder operation is carried out quickly and orderly, the builders control the number of 30 meters and 40 meters of T beam prefabricated to ensure that the needs of the site are met and the balanced production is achieved.
▲ On March 22, 2021, the first beam of the whole line was erected at the Jihegou Bridge
Due to the terrain constraints, the prefabricated T beam can only be transported to the work site by forming the subgrade, and the maximum longitudinal slope of the formed subgrade is 5.95%, which is large, which puts forward a severe test for the operation of the transport beam. Technical personnel strictly control the roadbed compaction, horizontal and vertical curve radius and other key indicators to ensure that the transport beam channel meets the requirements of transport operations, at the same time, The Taiyuan Company of the Sixth Bureau of China Railway selects professional drivers to drive the girder vehicles, sets up special personnel to supervise along the line, nearly 500 girder operations, safety zero mistakes.
During the erection process, the builder strictly follows the safety operation procedures to carry out the girder operation, and when the construction of the girder on the upper cross-county road and the township road girder, the construction protector carries out blockade protection at 300 meters on both sides of the construction site, prohibiting all foreign vehicles and pedestrians from entering. After more than half a year of girder operation, all 13 bridge T girders were erected, and the entire line was opened to traffic to enter the countdown.

New traffic, new leaps. After the completion and opening of the Beishan Transit Highway in Xingxian County, it will greatly alleviate the traffic pressure of the national highway in Xingxian County, effectively drive the economic development of townships and villages along the route, and is of great significance to improving the environment of Xingxian County, improving infrastructure construction, and enhancing residents' happiness and sense of gain.
