Embodiment Construction

[0026] Embodiment Referring to Figures 1-3, the tunnel lining trolley of the present invention includes a tunnel-shaped formwork, a trolley in the formwork, and a formwork entry and exit system. There is a grouting port on the formwork, and the grouting port is connected to the grouting system. Each set of templates has two observation windows.

[0027] The template is welded by panels 101 , frame plates 102 and ribs 103 .

[0028] see Figure 4 , in order to increase the overall rigidity of the template, reduce the amount of deformation, and reduce the steel consumption of the template, the rib plate 103 of the template is U-shaped. Both sides of the opening are welded to the panel.

[0029] A set of templates includes a top template 1, two side templates 2 and two bottom templates 3, and the cross section of the interface between the top template 1 and the two side templates 2, and between the two side templates 2 and the two bottom templates 3 is bell-shaped. , the outer ...

Abstract

The invention is a tunnel lining carrier, where a group of templates comprises top plate, two side templates and two bottom templates, the cross sections at the interfaces between the top template and the two side templates and between the two side templates and the two bottom templates are horn-shaped, and their outer edges are hinged with flat top hinge and their inner edges are connected with regulating screws; a template bracket comprises top longitudinal beam, cross beam, bottom longitudinal beam, column and inclined strut. And the carrier comprises door frame, girder summer and moving system; folding supports arms are connected between the bottom surface of the crossbeam and the bottom ends of the two side templates, side moving hydraulic oil cylinder is connected between the bottom longitudinal beam and the girder summer, expanding hydraulic oil cylinders are connected between the large arms of the folding support arms and the two bottom ends of the top template, and opening hydraulic oil cylinders are connected in the horn-shaped positions between the side and bottom templates.

Description

(1) Technical field [0001] The invention relates to a building construction machine, in particular to a tunnel construction lining formwork trolley. (2) Background technology [0002] The existing lining formwork trolleys used in tunnel construction all adopt the technical scheme of taking the trolley as the main load, generally including the arc-shaped trolley formwork, the trolley in the trolley formwork, the formwork entry and exit system and the operating platform, and the trolley The formwork is composed of a top formwork, two side formworks and two bottom formworks hinged in a single layer. There is a grouting port on the upper end of the top formwork, and the grouting port is connected with a grouting pipe and a grouting pump for concrete pouring. The main problems in the existing technology are: the formwork is fully supported by trolleys, difficult to adjust, low in strength, easy to deform, poor in compression resistance and floating resistance, high requirements f...
