Liugong ouweimu thrust beam construction technology to achieve the first three       

In August 1, 2014, after 8 hours of pushing construction, Zhengzhou City Longhai Road Viaduct fast track project two tenders, the first section of corrugated steel web PC beam Liugong engineering company successfully developed ouweimu push in place. The corrugated steel webs PC beam jacking construction made three innovations: one is the corrugated steel webs push beam is the first in the domestic; two is pushing beam single or double length is the length of the most Chinese; three is the use of inclined web design, web inclined angle of 75 degrees, while using the corrugated steel web plate made by the beam, which is also the first domestic, to fill the gaps in the corresponding technology.

The launching construction of corrugated steel webs composite beam is the first domestic key project in the fast track project of Zhengzhou Longhai urban viaduct. It is also a key municipal engineering project in Zhengzhou. Zhengzhou Long Hai Expressway two standard corrugated steel web PC composite beam length of 940 meters. The jacking construction for YU01 combined box girder of the first section of South Demi box girder, 27.5 meters long, 12.75 meters wide, steel webs and precast concrete weight of 910 tons, the pushing pulling method of construction process, pushing forward a length of 32.3 meters, the average hourly push speed of 6 to 8 meters. The pushing distance is 575 meters.

The smooth realization of the major target node marks, Liugong OVM engineering company in pushing beam construction of new technology has made a major breakthrough, has become the country's first push of corrugated steel web PC composite beam construction unit, to achieve the three first in the country in the field of. The smooth pushing of the first section of the beam indicates that the pushing construction technology has been successfully used in the project, and the high praise of the owner and the Party A has been obtained.
