The construction of the Bridge of the Yuhangtang River Bridge is over!Enter the countdown

At the construction site of the Yuhangtang River Bridge on the ground road on the ground road of Yunxi, workers are underwriting the reinforcement mesh. This is a necessary process before the bridge paving. "There are rainfall these days, and the rinse work is more effective. Next, the paving and guardrail construction of the bridge deck will also be steadily promoted. It is expected that in late August, the Yuhangtang River Bridge will complete all construction tasks." The project leader will be completed. " Xu Mingjie said.

The Yuhangtang River Bridge is 356m in length, connects to Provincial Highway 207 in the north, and in the south of Yuhangtang Road. It is an important part of the traffic throat in the future science and technology city. In particular, as an ground supporting project of the Hangzhou West Station Hub, ensuring that it can open traffic before the trial operation of the West Station Hub is the goal of the current Yuhang Transportation Construction.

Looking back at the construction of the Yuhangtang River Bridge, the western half was opened in November 2021, the beam frame was completed in March 2022, and the bridge was officially opened on April 25; The pile foundation construction was completed on May 27th, the downward structure construction was completed on June 25, and the beam frame was set on July 18. The construction process of the Yuhangtang River Bridge is fully in line with the construction plan, and it is so surprising that this is due to the repeated calculation of the project management personnel, the interspersed construction of the construction personnel, and the multi -form lifting.

The Yuhangtang River Bridge has a total of 17 spans and 35m. It is both under the viaduct and the construction of a multi -bridge across construction. There is a certain difficulty in the project. How can we complete high -quality projects within the prescribed time limit? After repeated discussions, the project decides to use a variety of construction methods that cooperate with each other, that is, beams other than viaduct projection through the construction lane and hang them with ordinary cranes; Use a bridge rack. Various construction processes are seamlessly connected, and the beam plate was successfully completed in the shortest time.

The construction of the project must also overcome the "big difficulties" of tasks and tight time. Especially at the same time as "building the bridge", it is also necessary to "demolish the bridge". After the construction of the 320 National Highway ground project, the traffic organization schemes were used to open to traffic. In order to solve the problem of non -motorized vehicles, the project was set up on both sides. In other words, there are more than one old bridge to "dismantle", but also two steel trestle bridges. Under this kind of construction pressure of "increasing time", the project construction personnel will flexibly arrange the construction process and abandon the traditional disassembly. The steps of piles are used to divide the bridge that need to be demolished into several segments in the method of "demolition and construction synchronization". Although such construction methods have increased costs, the bridge demolition period has also shortened nearly two -thirds.

In addition, after the two -way opening of the Yuhangtang River Bridge section of Yunxi Road, there is also a major benefit: Yuhangtang Road and Wenyi West Road are the main roads connecting Hangzhou City. Wenyi West Road interacts with an elevated upper frame, and there are Wenyi West Road Tunnels quickly connected, but the vehicles driving from Yuhangtang Road can only go on the ground road on the ground road on the ground road, and it encounters half of the roads and projects during construction. There are many vehicles, and the travel experience is very poor. After the transportation of the Yuhangtang River Bridge is open, there are 6 lanes in both directions. The morning and evening peak periods are expected to reduce the traffic jams of about 20 minutes.
