The hottest pump truck railway construction of XCM

XCMG pump truck railway construction shows its magic power

Guide: XCMG pump truck Yangwei is the first cross XCMG pump truck in Asia to participate in the construction of Hutiaomen bridge project of Guangzhou Zhuhai railway. Since August 2010, XCMG construction machinery has successfully achieved the sales of XCMG pump trucks in Zhuhai, Guangdong Province through unremitting persistence and efforts, breaking the industry monopoly of competitors in the region at one fell swoop

XCMG pump truck participated in the construction of Hutiaomen bridge project of Guangzhou Zhuhai railway

since August 2010, XCMG construction machinery has successfully achieved the sales of XCMG pump truck in Zhuhai, Guangdong Province through unremitting persistence and efforts, breaking the industrial monopoly of competitors in the region at one fell swoop, and establishing the image and reputation of XCMG pump truck! And to a large extent, it has improved its popularity and market share. Among the pump trucks sold, three hb41, hb48b and hb48a-iii participated in the construction of Hutiaomen bridge project of Guangzhou Zhuhai railway, which is known as "the first span in Asia"

the Guangzhou Zhuhai railway, known as the "Zhuhai destiny project" and the "2008 No. 1 project", was officially approved by the Ministry of Railways on April 25th, 2008, setting the railway specification as a national class I electrified railway. It starts from Jiangcun Marshalling Station of Beijing Guangzhou railway, runs through Guangzhou, Foshan, Jiangmen, Zhuhai and other four cities, and ends at Gaolan Port of Zhuhai, with a total length of nearly 190 kilometers. There are 10 stations along the way. The whole road is mainly freight transportation, taking into account passenger transportation. The planned annual freight volume is 60million tons. At that time, Zhuhai will form a sea, land and air transportation network

the biggest difficulty in the construction of Guangzhou Zhuhai railway is the Hutiaomen super major bridge, which is a "national key super major project". The bridge crosses the Hutiaomen waterway of the Pearl River and connects Zhuhai Doumen and Jiangmen Xinhui at both ends. It has a total length of 2507 meters and a total of 63 spans, of which pier 26 to pier 34 span the primary navigable main channel. In order to maintain the two-way navigation capacity of the channel, Hutiaomen bridge is designed as a three hole continuous steel arch bridge with an aperture of 120 meters, 248 meters and 120 meters, of which the 248 meter basket arch has the longest span among similar bridges in Asia. Therefore, the Tiger Leaping gate bridge will be "the first span in Asia" after its completion

because the pouring system of Hutiaomen bridge should have little resistance to material flow; The two main piers need to carry the 248 meter long basket arch continuous beam and the passage of trains. Therefore, the slump control of concrete is extremely strict. C60 slump concrete is used, which has extremely high requirements for concrete pumping machinery. Other brands of pump trucks cannot pump such high-strength concrete, while XCMG pump trucks meet the difficulties and fully meet the high requirements of construction conditions. Multiple pump trucks operate at the same time and complete the construction tasks on time and quality, The superior performance, stability and reliability of the products have won high praise from customers

XCMG 37 meter pump truck Tianjin Qinhuangdao passenger dedicated line shows great prestige

recently, XCMG pump truck was under construction on the Tianjin Qinhuangdao passenger dedicated line, and its good construction performance was praised by customers, which once again proved that XCMG concrete pump truck is not only a powerful builder of high-rise buildings, but also a strong builder of high-speed railways and culverts

Tianjin Qinhuangdao passenger dedicated line is an important part of the national medium and long-term railway planning. It starts from Tianjin west railway station and ends at Qinhuangdao. The main line is 261 kilometers long and the design speed is 350 kilometers per hour. After opening to traffic, the travel time from Tianjin to Qinhuangdao will be shortened from the current two and a half hours to one hour, and will be connected with three high-speed railway lines, Beijing Shanghai, Beijing Baotou and Harbin Dalian, forming a rapid rail transit network connecting the Yangtze River Delta, the Pearl River Delta and the three northeastern provinces

at present, the bridge of Tianjin Qinhuangdao passenger dedicated line is 37 meters, 10 meters underground and 27 meters above the ground; C50 high-grade concrete shall be used underground and 5 meters above the ground to strengthen the corrosion resistance and ensure the construction quality of passenger dedicated line. However, this kind of high-level low-temperature tank adopts single-chip microcomputer technology to control the concrete number, which is more likely to cause problems such as blockage of pump truck delivery pipe

XCMG hb37a used low pressure, small displacement, continuous and stable quality to pump C50 concrete, and there was no pipe blockage once; When pumping C30 concrete, high pressure and large displacement are adopted, and the pumping is successfully completed. The manager of the project department said, "I didn't expect XCMG pump truck to perform so well. When pumping C50 concrete, there was no pipe blockage, which was better than other brands of pump trucks I used."
