Description
Technical field
The utility model relates to tunnel construction machinery, and especially relating to a kind of tunnel lining trolley does not have faulting of slab ends lap device and tunnel lining trolley.
Background technology
Last procedure of tunnel construction is a secondary lining; The secondary lining practical implementation is earlier the past template outside, the sprue gate of passing through tunnel lining trolley afterwards again placing of concrete to be adjusted in the position of tunnel lining trolley, because the pressure that the concrete pressure that bears in the middle part of the top template of tunnel lining trolley bears greater than both ends, so the integral mold plate of chassis can occur bending and deformation; Because the template of whole tunnel lining trolley all can be born very big pressure; The template of chassis is sunk in distortion by bending, so template and the template after the lining cutting before lining cutting have certain distance, thereby has formed faulting of slab ends in lap-joint; This faulting of slab ends phenomenon unit in charge of construction generally can adopt the method for filling up and polishing to eliminate; This not only will reduce efficiency of construction, prolongs the duration, and has increased workload; Dust during polishing can impact the healthy of constructor, and filling up also influences attractive in appearance with burnishing part.
The utility model content
The purpose of the utility model is to provide a kind of tunnel lining trolley not have the faulting of slab ends lap device; Stressed because of the top template when the secondary lining fluid concrete to solve existing tunnel lining trolley, thus integral mold plate slight bending and sinking cause lap-joint to occur the technical problem of faulting of slab ends easily.
The further purpose of the utility model is to provide a kind of tunnel lining trolley that includes said no faulting of slab ends lap device.
The purpose of the utility model realizes through following technical scheme: a kind of no faulting of slab ends lap device of tunnel lining trolley comprises chassis arched top template, the end connecting plate; Chassis arched top template has the extension, and this extension has and the identical arc of chassis arched top template; Also comprise the overlap joint bearing, be positioned at the bottom, extension, be connected with the end connecting plate; The overlap joint bearing is provided with some adjustment bolts along the arcuate directions of extension, butt to extension lower wall during the adjustment working bolt.
Further; The overlap joint bearing is to be made up of bearing junction plate, adjustment bolt plate, plurality of strengthening ribs plate and welded nut; Said bearing junction plate has concentric inside and outside arc, and inside and outside arc and arc length arc and the arc length with the extension is corresponding respectively; The bearing junction plate is connected with the end connecting plate through bolt; The plane of adjustment bolt plate is overlapped to form mutual vertical plane along the outer arc respective curved of said bearing junction plate; Said reinforcement gusset has orthogonal dual-side, and said dual-side butt respectively is fixed to two vertical planes of adjusting bolt plate and bearing junction plate; Said reinforcement gusset distributes along bearing junction plate length direction spacing; Said welded nut is consolidated in two and strengthens on the plane of the adjustment bolt plate between the gusset.
The purpose of the utility model realizes through following technical scheme: a kind of tunnel lining trolley, this tunnel lining trolley are provided with said no faulting of slab ends lap device.
The utility model, because chassis arched top template has the extension, the extension has and the corresponding arc of chassis arched top template, this extension can overlap below lining concrete during work.In addition, be connected with the overlap joint bearing in the bottom of extension and the end connecting plate of chassis, this overlap joint bearing is provided with the adjustment bolt along the arcuate directions of extension; Through the adjustment bolt extension of top template tightly is attached on the pouring concrete during work; Like this, can guarantee on the one hand extension and the seamless overlap joint of pouring concrete, be out of shape with the part that the frictional force of extension is offset top template through pouring concrete on the other hand; Prevent that effectively concrete lap-joint from producing the faulting of slab ends phenomenon; Thereby avoided filling up and polishing operation, reduced workload, improved efficiency of construction and quality.
Description of drawings
Fig. 1 does not have the overall structure sketch map of faulting of slab ends lap device for the utility model tunnel lining trolley;
Fig. 2 among Fig. 1 along A-A to the figure that analyses and observe.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further explain.
See figures.1.and.2; The utility model tunnel lining trolley does not have faulting of slab ends lap device embodiment; Comprise chassis arched top template 7, end connecting plate 702, overlap joint bearing 9; Wherein chassis arched top template 7 has the extension 701 of stretching out the end, and extension 701 has the arc identical with chassis arched top template 7; 701 bottoms in the extension are connected with overlap joint bearing 9, and overlap joint bearing 9 is provided with some adjustment bolts 905 along the arcuate directions of said extension 701, butt to extension 701 lower wall during 905 work of adjustment bolt.
Overlap joint bearing 9 is made up of bearing junction plate 901, adjustment bolt plate 902, plurality of strengthening ribs plate 903 and some welded nuts 904; Wherein, The dual-side width of bearing junction plate 901 equates; Have concentric inside and outside arc, and outer arcuate and arc length arc and the arc length with extension 701 is corresponding respectively; The some connecting bolts 11 of bearing junction plate 901 usefulness are connected with end connecting plate 702; The plane of adjustment bolt plate 902 is along the outer arc respective curved of bearing junction plate 901, and one of which side and bearing junction plate 901 are overlapped to form mutual vertical plane; Strengthen gusset 903 and have orthogonal dual-side, this dual-side butt to two vertical planes of adjusting bolt plate 902 and bearing junction plate 901 respectively is fixedly connected; Strengthening gusset 903 is equally spaced along bearing junction plate 901 length directions; Welded nut 904 is welded on per two and strengthens on the plane of the adjustment bolt plate 902 between the gusset 903.
During work, the adjustment chassis makes extension 701 and pouring concrete 8 overlap joints; Adjustment bolt 905 holds out against extension 701 on pouring concrete 8, and then pours into a mould; After treating that newly placed concrete solidifies fully; Unclamp adjustment bolt 905 again, the lap-joint between pouring concrete 8 and the newly placed concrete will smooth, realizes no faulting of slab ends.
The utility model tunnel lining trolley is provided with said no faulting of slab ends lap device.
