Abstract
The utility model discloses a universal lining trolley for tunnel construction. The universal lining trolley is composed of a gantry bracket and a top-die truss, wherein the top-die truss is arranged above the gantry bracket, and the gantry bracket is composed of a gantry beam, two side gantry pillars and an inclined gantry struts supported among the gantry beam and the two side gantry pillars; and a top-die chord member in the top-die truss is supported on the gantry beam by a jacking cylinder. The universal lining trolley for tunnel construction is characterized in that the top-die chord member and the gantry beam are in segmented arrangement at the center and are connected by bolts at the segmented positions; and widened top-die chord members and widened gantry beams which are connected by bolts and can be detached are respectively arranged at the segmented positions of the top-die chord member and the gantry beam. According to the utility model, lining trolleys with different widths can be set according to the requirements of tunnel construction, thereby improving the utilization rate of the lining trolley, saving materials, and reducing the cost of tunnel construction.
Description
Technical field
The utility model relates to a kind of constructing tunnel equipment, a kind of applicable two lining construction lining trolleys in the different section tunnel of more specifically saying so.
Background technology
Along with expanding economy, the railway in the infrastructure, the construction of highway tunnel constantly increase, and in the practice of construction, because the Tunnel Design section has nothing in common with each other, cause the two lining chassis utilization rates of using in the work progress low.
Two lining chassis are nonstandard products indispensable in the tunnel double-lining work progress, are used for the concrete lining construction to the tunnel inwall.Because form surfacing adopts the monoblock steel plate cold bending assembled; So concrete surface smooth after the tunnel double-lining demoulding, splicing seams is little, and outward appearance is beautiful attractive in appearance; Reduce the labour intensity of mounting template simultaneously in the work progress greatly, so two lining chassis become the special equipment of tunnel double-lining construction.Because two lining chassis belows need be open to traffic, so the door frame crossbeam generally is not less than 5.5m.
At present, two lining chassis in the tunnel double-lining construction adopt prefabrication more, and this chassis is narrow application range in actual use, can not satisfy multibreak constructing tunnel; Cause stock utilization low thus, the waste resource, cost is high.
The utility model content
The utility model is for avoiding above-mentioned existing in prior technology not enough, provide a kind of constructing tunnel universal lining trolley, expending to satisfy various road and rail constructing tunnels, saving material and minimizing.
The utility model adopts following technical scheme for the technical solution problem:
The universal lining trolley of the utility model constructing tunnel is to be made up of door shaped stent and the backform truss that is positioned at door shaped stent top, said door shaped stent be by door frame beam, both sides door frame post and be supported on the door frame beam and both sides door frame post between the door frame diagonal brace constitute; Backform chord member in the backform truss is bearing on the said door frame beam by jacking cylinder; Its design feature is that said backform chord member and door frame beam are in the central segments setting, and on the position of segmentation, connects with bolt; Setting can be respectively be connected with bolt on the segmentation position of backform chord member and door frame beam and removablely widens the backform chord member and widen the door frame beam.
The design feature of the universal lining trolley of the utility model constructing tunnel also is between said both sides door frame post and door frame beam, the reinforcement diagonal brace to be set.
Compared with present technology, the utility model beneficial effect is embodied in:
1, the utility model is applied widely, can satisfy the constructing tunnel of multiple different section width, and economic results in society are remarkable;
2, the utility model steel structure material is reusable, has reduced spillage of material, reduces cost;
3, the utility model can be simplified manufacturing process, reduces the constructing tunnel cost.
Description of drawings
Fig. 1 is the utility model light section chassis front schematic view;
Fig. 2 is the big section chassis of a utility model front schematic view;
Fig. 3 is the utility model chassis side schematic view.
Label among the figure: 1 door frame beam; 2 door frame diagonal braces; 3 door frame posts; 4 prepared screw-bolt holes; 5 backform chord members; 6 widen the door frame beam; 7 widen the backform chord member; 8 strengthen diagonal brace.
The specific embodiment
Referring to Fig. 1, Fig. 2 and Fig. 3, identical with prior art is that universal lining trolley is to be made up of door shaped stent and the backform truss that is positioned at the door shaped stent top equally in the present embodiment.Wherein, door shaped stent be by door frame beam 1, both sides door frame post 3 and be supported on door frame beam 1 and both sides door frame post 3 between door frame diagonal brace 2 constitute; Backform chord member 5 in the backform truss is bearing on the door frame beam 1 by jacking cylinder.
Shown in the figure, with backform chord member 5 and door frame beam 1 segmentation setting on middle position, and on the position of its segmentation, connect and compose overall structure in the present embodiment with bolt; In order to adjust the width of chassis, setting can be respectively be connected with bolt on the segmentation position of backform chord member 5 and door frame beam 1 and removablely widens backform chord member 7 and widen door frame beam 6.
For guaranteed strength, can between both sides door frame post 3 and door frame beam 1, increase to be provided with and strengthen diagonal brace 8, strengthen diagonal brace 8 and be bolt hole 4 through reservation on door frame post 3 and the door frame beam 1 and carry out bolt and be connected, with easy disassembly.
In the practical implementation; Lining trolley is in the tunnel during big section; In the centre of door frame beam 1 and backform chord member 5 according to tunnel cross-section width setting widening door frame beam 6 with widen backform chord member 7; Between door frame beam 1 and door frame post 3, increase simultaneously and strengthen diagonal brace 8, to increase the rigidity (as shown in Figure 2) of lining trolley; When the narrow-bore tunnel, remove and to widen door frame beam 6 and to widen backform chord member 7, also remove simultaneously and strengthen diagonal brace 8, increase the space (as shown in Figure 1) that is open to traffic, chassis below with this.
Claims (2)
