Embodiment Construction
[0026] Such as figure 1 , 2 Among them, a steel mold trolley for the concrete lining of a tunnel with a rounded rectangular section, including a portal frame. In a preferred solution, the portal frame is a frame column composed of a plurality of portal frame columns 2 and portal frame beams 4, and each frame The frame structure is composed of portal frame ground beams 1 and portal frame longitudinal beams 3 between columns, and diagonal braces 11 are arranged in the frame structure to strengthen the structure, such as figure 2 shown in .
[0027] A running device 12 is provided at the bottom of the door frame. Preferably, the running device 12 includes a wheel base on which the wheels are mounted. Preferably, a drive mechanism for driving the wheels to rotate is also provided, which is not shown in the figure. With this structure, it is convenient to move the trolley to the working position.
[0028] Such as figure 1 Among them, the top of the gantry is connected to the ...

The invention provides a steel mould trolley for concrete lining of a rounded rectangle cross section tunnel. The steel mould trolley comprises a gantry, the top of the gantry is connected with a top framework frame through a plurality of top framework hydraulic cylinders, the two sides of the gantry are connected with side framework upper framework frames through a plurality of side framework hydraulic cylinders; the tops of the side framework upper framework frames are provided with arc segments, the inner sides of the arc segments are provided with upper framework frame supporting rods, the top of the side face of the gantry is provided with side framework frame supporting lug plates, and the upper framework frame supporting rods are hinged to the side framework frame supporting lug plates. The side framework frame supporting lug plates are provided with long sliding grooves, the upper formwork frame supporting rods are provided with upper framework frame hinge pins, and the upper framework frame hinge pins rotate in the long sliding grooves and can slide in the long sliding grooves. By the adoption of the structure, investment of manpower and materials can be reduced, and the concrete lining construction period of the rectangle cross section tunnel can be shortened, and good concrete forming quality is achieved. Operation is simpler and more convenient, and different formwork assemblies cannot interfere with one another.
Description
technical field [0001] The invention relates to the field of tunnel concrete lining construction, in particular to a steel mold trolley for tunnel concrete lining with rounded rectangular cross-section. Background technique [0002] With the rapid development of municipal construction and the application of new excavation technology, in order to make full use of the underground space, due to the low space height, rectangular cross-section tunnels have been paid attention to again. In the construction of concrete lining of rectangular cross-section tunnels, most of the existing projects adopt the method of erecting full-wall brackets or using simple trolleys for concrete lining construction. It will make it difficult to meet the requirements of project quality and construction period. [0003] Chinese patent document CN 203756189 U discloses a demoulding and drawing device for a steel formwork trolley in an arc section of a tunnel, which comprises a steel mold trolley, and a...
