The main tower of the Luohe Bridge of Linyi Tongda Road is expected to be completed in September

Tongda Road Luohe Bridge and the cross -strait interchange transformation project steadily advanced to be completed in September.

At the construction site of the Luanhe Bridge of Tongda Road in Linyi City and the cross -strait cross -strait traffic renovation project, the builders of the Linyi Municipal Group's Seven Company used to adhere to the steady progress of the project construction. The main tower of the Luohe Bridge of Tongda Road is 100 meters high, and the lower part of the lower part is a concrete pouring structure, and the upper part is 84 meters in the steel structure. The higher the height of the main tower, the more accurate positioning requirements, and more difficult.

Some time ago, high temperature continued, and the steel structure was greatly affected by temperature, which brought great difficulties to precise positioning. "Affected by the temperature difference between morning and evening, the diameter deviation of the steel structure can reach up to 4 cm, but its positioning accuracy must be accurate to millimeters. This is a difficult problem for summer in high temperatures." Sun Zengming, the person in charge of the project main bridge project, said that in order to solve the problem of precision positioning of the steel structure, after many studies, it finally decided that no matter when the steel structure was lifted, it was roughly adjusted first. Precise adjustment to ensure the accuracy of the main tower hanging position.

Not only high temperatures, but also one of the factors that restrict the progress of the construction of the project. Flood prevention work is important. In June, it is a critical period for flood prevention.

Luohe is the largest one -level tributary of Yijiang. Every time in the flood season, Luohe has become the focus of flood prevention work. The Tongda Road Luohe Bridge Project, which is located above the Luohe River, originally planned to adopt traditional plate buckle brackets as the box beam support system. However, in order to ensure the safety of flooding, the project department adjusted the plan in advance before the flood season. The construction support system with a small bracket beam, each two brackets is 9 meters, which greatly guarantees normal flooding.

"Before entering the flood season, we have cleaned up all the materials and coffin in the river beach, evacuated all the machinery, removed the temporary bridge of 80 meters long, and dredged the drainage systems such as rain wells and rainwater pipes around the construction site to ensure that the rainwater was normal. Excess. "Yu Qian, the person in charge of the construction of the traffic reconstruction project on Tongda Road and the cross -strait interchange transformation project, introduced," Because the cross -strait interchange is low -lying on the ground, it is the "object" that focuses on the flood season. And pull the police ring line within the river beaches on the north and south sides of the strait, arrange personnel on duty for 24 hours to observe whether there are stagnant water. "

In order to cope with the flood season, the project department prepares flood prevention emergency supplies in advance, establishes and improves flood prevention emergency plans and duty on duty, formulates flood prevention emergency plans, and conducts daily inspections of flood control safety at the construction site to prevent problems before it occurs. At the same time, the project department adjusts the construction plan in a timely manner to ensure that the project construction is progressing steadily according to time nodes.

Although the project progress was not affected by the dual "pinching" of high temperature and flood season. Up to now, the lower part of the Bridge Bridge of Tongda Road Luanhe Bridge has been completed, and the box beam has completed 40%of the overall progress. Among them, the paddling box beams have 22 units, and 9 units have been completed. Liang Gong 5 union is currently being lifted. It is planned to complete all steel box beams in November. The main tower has a total of 7 sections. At present, the fifth section has been completed, and the overall progress has been completed by 80%. It is expected that the main tower is completed in September, and the lava system construction is expected to be completed in September. The main structure of the North -South Interchange has been completed by 95%, and it is undergoing the construction of subsidiary projects such as greening, backfilling, seedling planting, and pedestrian lane paving.

As the key people's livelihood project in our city, after the completion of Tongda Road Luoheqiao Project, a convenient transportation network will be formed between the North City New District and the Lantashan Old Town, which will improve the quality of people's life. It is of great significance to achieve capacity expansion.

The goal is before, responsible. "In the next construction gold season, we will continue to carry forward the spirit of the iron army of" Fengshan open roads and water frames' on the premise of ensuring safety, quality and civilized construction. Complete construction tasks! "Wu Shifeng, manager of the seven companies of Linyi Municipal Group.
