Application scenario
The applicable scenarios for automatic hydraulic inverted arch wharf include:
1) Construction of Extra Long Tunnels and Complex Terrain
① Construction of the inverted arch of the extra long tunnel
Suitable for railway and highway double track extra long tunnels, the fully automatic hydraulic wheel design is used to achieve full width pouring of inverted arch concrete, significantly improving construction efficiency and shortening the construction period.
② Step excavation scene
Adapt to various step excavation techniques, and meet the construction requirements of "early closure and early ring formation" through the linkage and coordination of the wharf and inverted arch formwork, reducing the risk of deformation of tunnel surrounding rock.
2) Efficient construction and complex working conditions
① High load demand scenario
Capable of carrying a load capacity of over 50 tons, the pressure is evenly distributed through a flexible base and automatic running track, ensuring safe passage of construction vehicles even during the incomplete hardening stage of concrete.
② Automation and Intelligent Homework
Adopting hydraulic control technology, it supports up and down, left and right adjustment of the wharf and automatic walking of the electric controlled trolley, which can be controlled by one person. The degree of automation far exceeds that of traditional wharf, reducing the need for manual track laying.
3) Urban and Underground Engineering
① Urban underground comprehensive pipe gallery
Suitable for the construction of narrow spaces such as urban underground roads and subway tunnels, modular design reduces the occupation of ground resources, and enclosed operations reduce interference with the surrounding environment.
② Rapid construction scenario
Through full hydraulic drive and integral inverted arch formwork configuration, concrete pouring, demolding, and wharf movement can be quickly completed inside the tunnel, with a comprehensive efficiency improvement of over 30%.
4) Adaptation to special construction environments
① Complex geological conditions
The design of flexible base and high elasticity rubber pad can adapt to uneven ground during concrete pouring, ensuring even stress distribution on the wharf and reducing dependence on foundation stability.
② High precision construction requirements
Combining BIM technology to optimize the positioning and load distribution of the wharf, meeting the stringent requirements for the flatness and impermeability of the arch concrete in high-speed railway tunnels.
Note: In practical applications, the parameters of the wharf need to be selected based on the tunnel section size, geological conditions, and construction progress. For example, full width pouring technology is preferred for double track tunnels, while the durability of the flexible base needs to be verified for high load scenarios.
