The typical lining trolley has disadvantages such as
complex structure, enormous span, extremely large size, challenging assembly,
and high cost when applied in the lining construction of giantspan
flat underground caverns. The lining construction of the giantspan flat underground cavern is distinguished by its vast volume,
large area, large selfweight, and thick reinforcement.
A new heavyduty lining trolley with a pushing sliding
buckle support system comprising the technical advantages of the buckle support
system and fullyhydraulic lining trolley is designed
and developed for an underground cavern with a span of approximately 70 m and a
rise to span ratio of approximately 0.21. The trolley is composed of jacking
adjustable formwork, buckle support gantry, pushing sliding chassis, rotary
butt joint distribution, and plugin vibration
technology. These components are supported by hydraulic and electrical control
technologies, integrated with numerous other technologies such as trolley selfpropelled technology, concrete pouring, vibration, maintenance, and
monitoring. The successful application of the trolley in an enormous
underground cavern reveals that the heavyduty lining
trolley with pushing sliding buckle support has the advantages of simple
structure, high strength, strong bearing capacity, and ease of assembly, which
can effectively reduce labor intensity and cost, and improve construction
efficiency and quality.
