Recently, the second lining trolley produced by Tengyu Machinery has been installed and accepted at the entrance of Lijiacun Tunnel in the Chongqing Kunming project of China Railway 12th Bureau. Becoming an iconic construction project again.
The installation of the second lining trolley has achieved rapid mold insertion, changing the drawbacks of the original shuttle groove construction and ensuring that the feed at each port is pumped. During construction, the project department meticulously organizes and scientifically manages, adhering to the construction principles of "safety first, quality first" and "high standards and strict requirements". The "three inspection system" and "hidden engineering site supervision system" are strictly implemented for processes such as geotextile, concrete anti void devices, waterproof board installation, steel bar binding, pre embedded channels, and trolley positioning. At the same time, prior to concrete pouring, professional technical personnel provided detailed technical briefings to on-site construction personnel. The construction unit, supervision unit, and others conducted on-site acceptance of the first piece of the pre embedded channel of the tunnel contact network, ensuring the orderly construction.
Tengyu has a modern enterprise management and after-sales service system, as well as a complete set of mechanical processing equipment. It has complete capabilities in the development and manufacturing of bridge and tunnel construction machinery and specialized equipment. We have successively launched steel formwork tunnel lining trolley series, trestle series, bridge steel formwork series, and hydraulic machinery and component series products.
The second lining construction (including the widening section) should adopt the whole hydraulic automatic walking lining trolley, the lining trolley should have accurate structure size, all kinds of telescopic components, hydraulic system, electrical control system running well, reasonable setting of supporting mechanisms; It should meet the requirements of automatic walking and have a locking device to ensure accurate positioning.
Steel formwork is a steel formwork used for concrete pouring and forming. In addition to steel formwork, there are also wooden formwork, plywood formwork, etc. Steel formwork is widely used in construction projects due to its multiple uses and beautiful appearance during concrete pouring.
