HJ900B type bridge erecting machine is suitable for the construction of bridges and tunnels in mountainous areas can pass the tunnel without dismantling, and the bridge erection equipment of the whole hole box girder of the tunnel mouth (5 meters) erection beam passenger dedicated line 32 meters and below, the bridge machine has: the C-shaped outrigger is adopted, and it has the function of transporting the beam car to transport through the double-line tunnel; Adopt a span fixed-point lifting and erection beam, the whole machine structure is simple, the high-level lower guide beam is adopted, and the beam transport vehicle is directly aligned with the beam feeding beam, and the bridge erecting machine is simply supported through the hole, the force is obvious, safe and reliable, and the stability is good; The mechanical, electrical and hydraulic integration technology is used, and the working mechanism moves quickly, accurately, safely and reliably, and the beam erection accuracy is go
When this bridge erection frame erects reinforced concrete segmental beam, assemble block by block according to the order of beam piece, apply prestress simultaneously, carry out dry joint, wet joint construction after the whole collapse segmental beam block is installed, make it a whole structure, and then carry out span-by-span installation according to the predetermined installation direction, advance step by span, and finally complete the construction of the whole bridge. Adopt this construction method to carry out bridge erection construction, not only ensure the quality of the project, but also solve the impact of the construction on the existing traffic very well, also save the land acquisition cost and the beam transportation cost of the beam making yard, especially suitable for the erection of the beam construction of the large-span bridge across rivers, lakes, railways, highways and urban roads.
The main arm of the bridge erecting machine has two structures: triangular truss and box girder. When the main boom is a triangular truss, the web member and the upper and lower chord are connected by steel pins, and the web members of the same type can be interchangeable and universal, and this innovative design makes the equipment dismantle the large components into small units when dismantling, which is convenient for automobile road transportation or container transportation. When the main boom is a box girder structure, the bridge erecting machine can swing the head and tail into a broken line, which can realize the construction of the segmental beam curve erection beam.
In addition to meeting the domestic bridge erection construction, the LG series segmental bridge erecting machine produced by the company has been exported to Malaysia, Israel, United States, Brunei and other countries.
Product Description:
Shanghai's first new urban railway "Airport Liaison Line" 1 standard girder was completed
On October 12, at the construction site of the first new urban railway "Airport Liaison Line" in Shanghai across the Shanghai-Chongqing Expressway Bridge, the operators of the group company operated a 700-ton bridge erecting machine to steadily land the last 32-meter-long box girder on the bridge pier. So far, the Shanghai Airport Liaison Line 1 has successfully completed the whole line of the girder, sounding the "charge" for the airport liaison line to enter the comprehensive sprint stage.
As Shanghai's first new urban railway, the Airport Link connects Hongqiao and Pudong, with a maximum speed of 160 kilometers per hour.
The 1st section of the airport liaison line undertaken by the group company is the starting section of the Shanghai airport liaison line and one of the only two bridge sections on the whole line, undertaking the erection task of 72-hole simply supported beams with a total of 2,226 meters. Due to the proximity of the beam erection area to the Shanghai-Kunming Railway, many constructions are within the scope of the railway protection area, the maximum erection slope is 27.8‰, and the minimum erection curve radius is 1000 meters.
In order to ensure the safe and smooth achievement of the node goal, since the start of the beam erection work on June 28 this year, the project department has scientifically organized the construction on the basis of implementing the measures for the prevention and control of the new crown pneumonia epidemic, combined with the characteristics of the bridge distribution and the topography along the line, and strengthened the safety control of the blockade construction of the business line erection beam. To ensure the construction progress of the project, the quality of the project continued to lead, and finally completed the girder construction task safely and smoothly in 106 days.
"The project has a large amount of girder engineering, and during the construction process, we continue to summarize and improve, strengthen dynamic adjustment, and successfully complete all the girder construction tasks one month ahead of schedule." Xue Fei, project manager of Shanghai Airport Liaison Line 1 Standard 1 Branch, said that after the completion of the box girder erection work, the project will enter the track and electromechanical installation stage.
After the completion of the project, the travel time between the two comprehensive transportation hubs of Shanghai Hongqiao and Pudong can be controlled within 40 minutes, and it can be transferred to a number of existing and under construction rail transit, which is convenient for citizens and passengers along the line. At the same time, it will further enhance the radiation role of Pudong and Hongqiao comprehensive transportation hubs in the Yangtze River Delta region, serve the Yangtze River Delta urban agglomeration, and provide strong support for improving Shanghai's global city energy level and core competitiveness, and implementing the national strategy of integrated development of the Yangtze River Delta.
