Abstract

The invention discloses a movable supporting shield for urban pipe gallery construction and limiting hinges of the shield. The movable supporting shield comprises multiple sequentially arranged shieldunits and limiting hinges, wherein each shield unit comprises shield walls which are arranged on the two side walls of a pipe gallery and a guard plate which is arranged on the external walls of theshield walls, every two adjacent shield units can move relative to each other, the guard plates of every two adjacent shield units are lapped in an interlaced manner, and each limiting hinge is arranged between the shield walls of every two adjacent shield units; each limiting hinge comprises a first connecting component, a first hinged plate, a second connecting component and a second hinged plate, wherein the first connecting component and the second connecting component are fixedly connected with the shield walls of every two corresponding adjacent shield units, the first hinged plate and the second hinged plate are arranged between the first connecting component and the second connecting component and hinged to the first connecting component and the second connecting component separately, and the first hinged plate is hinged to the second hinged plate. According to the movable supporting shield for urban pipe gallery construction and the limiting hinges of the shield, supporting ofthe pipe gallery can be formed on the condition that retaining wall piles do not need to be poured.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to a movable support shield and a limiting hinge for urban duct construction. Background technique [0002] Pipe capsules refer to public tunnels that are used underground to lay municipal pipelines such as electricity, communications, radio and television, water supply and drainage, heat, and gas. [0003] At present, in the construction of the capsule, it is basically used to pour retaining piles on both sides of the tunnel for temporary support, and under the protection of the retaining piles, the soil in the middle is excavated to form prefabricated and assembled structures or cast-in-place operations. Space for pouring construction of urban duct structures. Calculated at a distance of 3 meters and an average depth of 12 meters, 7,200 meters of wall retaining piles are required per kilometer. Calculated at 1,600 yuan per meter, the cost of temporary support projects for ...
