Description

Technical Field

[0001] The utility model relates to the technical field of construction trolleys, in particular to a lining trolley for a concealed excavated underground passage. Background Art

[0002] During tunnel pedestrian walkway construction, a pedestrian walkway lining trolley is required for pouring the walkway. A tunnel lining trolley consists of a trolley and formwork. The formwork is constructed with a steel frame, topped with steel plates to form the outer shell. It is equipped with a retraction mechanism, and an electric hydraulic device mounted on the trolley controls the erection and removal of the formwork. The formwork and trolley are independent systems. After pouring concrete for each lining section, the trolley can be detached from the formwork, leaving the lining concrete supported by the formwork structure. After retracting the formwork behind the next section, which has been filled with concrete and is ready for demolding, the trolley passes through the installed formwork and reaches the pre-cast section ahead for erection. However, existing lining trolleys are not easily self-propelled and are typically towed by a leveler, which occupies a significant amount of tunnel space. Furthermore, the trolley's lack of height adjustment limits its scope of use. Utility Model Content
