Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model, rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art obtain under not paying creative work premise, broadly fall into the scope of this utility model protection.
As shown in Fig. 1～7, a kind of large-diameter shield machine is with step concrete inverted arch making device, and including trestle 3, trailer 1 and trestle 3 are hinged by connecting device 2, coordinate tunneling synchronous.Being provided with bottom trestle 3 tiltedly that wheel is to 7, tiltedly wheel moves ahead offer support force to for trestle 3, and trestle 3 upper berth is equipped with track, and described track is twice, and section of jurisdiction transport marshalling and concreting marshalling can pass through trestle simultaneously, do not interfere with each other；Concreting marshalling 4 sails trestle into by inverted arch trestle back-connected upward slope track 8 device, carries out inverted arch Concrete Filled at trestle leading portion；Section of jurisdiction transport marshalling can proceed to trailer front portion, provides material for pipe sheet assembling.
Inverted arch making mould 5 is installed bottom trestle 3, inverted arch making mould 5 front portion is provided with dreg-accepting hopper 9, inverted arch making mould 5 includes side seal board 14 and top closing plate 12, left, it is connected by tightening regulator 18 between right side seal board 14, vertical locating oil cylinder 13 bottom trestle 3 is used for promoting top closing plate 12 to move along side shrouding directive wheel 15, cross cylinder 11 it is additionally provided with bottom trestle 3, cross cylinder 11 is connected with boots plate 10, trestle 3 both sides are additionally provided with the side shrouding locating oil cylinder 17 for constrained side banding plate directive wheel 15, side shrouding directive wheel 15 is connected with side seal board 14, side seal board 14 is connected by top closing plate directive wheel 16 with trestle 3.
In the application, it is filled with construction headspace for inverted arch under marshaling track laying and bridge in the middle part of trestle 3 bottom platform, coordinates tunneling synchronous, do not interfere with each other, do not produce impact.Inverted arch making mould 5 is installed bottom trestle 3, construction can be filled with at inverted arch under bridge, not interfere with each other, and described inverted arch making mould 5 and trestle 3 can self-movement, do not produce impact.
Wherein, tightening regulator 18 is tensioning bolt and nut.By regulating tensioning bolt, it is possible to regulate the distance between two side plates in left and right, tightening regulator can be finely tuned when concrete setting time.
A kind of large-diameter shield machine is with step concrete inverted arch paving method, carry out in the following manner: trailer 1 drives trestle 3 to move in tunnel by connecting device 2, tiltedly wheel is supported in tunnel-side to 7, the track by trestle that section of jurisdiction transport marshalling and concreting marshalling 4 can be simultaneously independent；Concreting marshalling 4 sails trestle into by inverted arch trestle back-connected upward slope track 8 device, carries out inverted arch Concrete Filled at trestle leading portion；Section of jurisdiction transport is organized as pipe sheet assembling and provides material；
The floating function of inverted arch making mould 5 is achieved in that concreting mouth is left in inverted arch making mould 5 front end, tank car travels to trestle, concreting is entered in mould, when shield advance followed by trestle 3, vertical locating oil cylinder 13 stretches out, top closing plate 12 is promoted to move along side shrouding directive wheel 15, it is achieved inverted arch making mould lag function；Cross cylinder 11 stretching out, retracting thus driving anterior boots plate 10 to move forward and backward, and the floating concrete built, unnecessary concrete is then fallen in anterior dreg-accepting hopper 9；
The demoulding functions of inverted arch making mould 5 is achieved in that after the filling of mould inner concrete is floating, regulate tightening regulator 18, the side seal board 14 about mould is made to separate with concrete, side shrouding locating oil cylinder 17 forward extends out, side seal board 14 synchronizing moving is driven time trestle 3 was moved forward, when fill is concrete, locating oil cylinder is retracted.
This utility model lays inverted arch trestle in shield machine trailer rear portion suitable distance, coordinates tunneling synchronous, trestle is provided with track, and can pass through section of jurisdiction marshaling and inverted arch casting concrete tank car；Meanwhile, under bridge, inverted arch is filled with construction, does not interfere with each other.Inverted arch trestle front and rear portions is connected to uphill, downhill rail set, in order to marshaling pass through, rear supporting inverted arch build marshaling go up a slope enter trestle, trestle carries out inverted arch concreting, with realize inverted arch fill be synchronously performed.This utility model apparatus structure is simple, dismantles easy to assembly, reasonable in design reliably.
More weak owing to just building complete concrete bearing capacity, for the problem solving train marshalling list transported material, supporting rear portion targeted design trestle work structure after shield, train marshalling list reaches trestle transported material to shield front end, and described trestle trailer supporting with after shield machine is connected, bottom arranges the mould of concrete inverted arch making, realize shield machine driving to be synchronously performed with the filling of follow-up inverted arch, optimize tunnel molding mode, improve concrete inverted arch filling quality, shorten the duration of a project, improve efficiency.After casting concrete, forming difference in height before and after inverted arch, for solving the problem (difference in height that marshalling is formed) of train marshalling list transported material by concrete inverted arch, trestle should possess following function:
1. trestle rear and front end arranges track uphill, downhill transition platform, and trestle is provided with track, it is achieved tunnel track organizes into groups track UNICOM with shield, meets the current of shield machine material transportation marshaling.
2. the realization built with step concrete inverted arch needs tank car that concrete is transported to trestle place, carries out inverted arch concreting on trestle, and therefore, trestle design should possess enough bearing capacitys and casting space.
3. being provided with casting space bottom trestle, first meet the layout building mould, length meets the strong times such as 30m concreting condensation.To ensure that inverted arch has enough intensity to meet the requirement that the current track of the equipment such as material marshalling is arranged.
This utility model requires the sliding mould of design for These characteristics, possesses following feature:
1. sliding formwork is step-by-step movement, meets after concreting completes under resting state, requirement to stable mould supporting before arriving molding condition；
2. after the demoulding, trestle provides counter-force to support, and realizes mould reach by oil cylinder, completes subsequent cycle and build the demand of distance；
3. sliding formwork top is provided with slide plate, rod etc., meets the demand of plane.
The foregoing is only preferred embodiment of the present utility model; not in order to limit this utility model; all within spirit of the present utility model and principle, any amendment of making, equivalent replacement, improvement etc., should be included within protection domain of the present utility model.
