Flying rainbow on the surface of Hongshui River，Across the Green Mountains and Beyond the Sky。
On the evening of March 14，The concrete pouring in the last arch rib main chord pipe of Zhenglong Hongshui River Bridge has been completed.。At this point，The pouring construction of the main chord pipe of the arch rib of the whole bridge has been completed。
Zhenglong Hongshui River Bridge is the largest half-through concrete-filled steel tubular arch bridge under construction by Guangxi Road Construction Group.，Yeah, too《Planning of Guangxi Expressway Network（2018-2030）》Medium“Connect 6 lines”Wuxin Expressway 2-Key Control Works of Division 1。The bridge is located in Laibin City, Guangxi Zhuang Autonomous Region.，The total length is 1404 meters，The main bridge is 316 meters long.，Spanning the Mother River that Nourishes the Maotu in Northern Guangxi——Red River。
The arch abutment of the whole bridge is poured with mass concrete.，The arch rib is a steel-tube concrete-truss structure.，8 arch rib main chord pipes in total，Pumping in 4 times，A total of 2454 injections are requiredm³YesC60 self-compacting concrete。
Because the northern Guangxi region is mostly karst landform.，Its terrain is complex.，There are many karst caves，There are many bad fissures.，And that geological development has great concealment.，The technical requirements for concrete pouring technology are extremely high.，It is also a great challenge to the selected equipment.。
To ensure that the project is on schedule，Six 10023 Truck-mounted pumps have become the main force of the pumping mission.，It basically maintains a 24-hour uninterrupted working state.，Two-stage relay pumping process is adopted.，Follow first inside、Posterolateral，Play the first string、Perfusion shall be carried out according to the principle of rear upper chord.。
In order to ensure the quality of concrete slurry and the stability of pumping pressure，The project department has launched a full-time-domain remote real-time monitoring system for Concrete Pumping quality.，Monitor the whole process、Precise control，Collecting the pressure value of the concrete slurry on the pipe wall in real times。This technology is the first comprehensive application of concrete pouring construction in the same industry.，It is also a major breakthrough in the intelligent informatization of the concrete-filled steel tube pouring construction process.。
According to theoretical parameters and past experience,，The SANY Vehicle-mounted pump can complete this task successfully.“Task”，But the process operators in the field still dare not slack off at all.，Keep a close eye on the concrete pouring，Cooperate with equipment tacitly，As always“Continuous and stable output”，Another breakthrough.，Achieve high standards、High quality、High efficiency concrete pouring。
At the same time，Guangxi Sanxin Service Team also responded quickly to the needs of the project department.，Regular inspection、Maintenance，Continue to escort the Hongshui River Bridge。
The head of the project department said：“We have worked with Trinity many times.，Jointly completed many landmark key projects in the Guangxi region.，The Truck-mounted pump that was ordered to go to war this time also lived up to expectations.，And that pipe is not bloc in the pouring proces.，The construction period is greatly shortened.，Ensure the progress of the project！Thumbs up for Sany Equipment，Thanks also to the SANY technicians.、Service personnel，It provides the greatest guarantee for high-quality and efficient construction.！”
It is reported that，After the completion of the bridge，It will greatly shorten the space distance between villages and towns on both sides of the Hongshui River.，Yes, it is convenient for people to travel.、Promote the development of tourism resources along the line、It has played a positive role in promoting rural revitalization and optimizing the Xingbin Expressway Network.。
