Abstract
The utility model relates to a grouting trolley for secondary grouting operation. The grouting trolley is connected behind the last section of frame of a shield tunneling machine, and comprises two sets of running trolleys and a plurality of connection rod pieces, two ends of each connection rod piece are respectively and fixedly connected with the top of the running trolleys arranged on two sides of the connection rod pieces, the running trolleys are of a double-layer frame structure, and a grouting machine, a stirring drum, cement and water glass are arranged on each running trolley. The grouting trolley has the advantages that the grouting trolley goes forward along with the shield tunneling machine, does not affect tunneling construction of the shield tunneling machine, improves timeliness of secondary grouting in a tunnel, greatly saves grouting time, moreover can not affect smooth operation of a haulage electric locomotive, enables the grouting operation to be concise and convenient, ensures that the ground surface subsidence is within a controllable range, and guarantees safety of ground surface buildings and pipelines.
Description
Technical field
The utility model relates to shield gantry car, is specifically related to a kind of slip casting chassis for the secondary grouting operation.
Background technology
When in soft soil layer, adopting shield method to carry out constructing tunnel, often need carry out secondary grouting with the control ground settlement.Usually the conventional secondary grouting mode that adopts is when needs carry out secondary grouting, with electric locomotive grouting equipment and material is transported in the tunnel, carries out slip casting by manually-operated then.Adopt this kind conventional method, the time that slip casting consumes is longer, because grouting equipment is placed in the tunnel, makes that the electric locomotive of transportation is impassable, can't carry out set of tunneling construction, after slip castings such as need finish, equipment is transported could recover tunneling construction.When carrying out the slip casting operation, need 3 workmans to operate simultaneously at least, and when needs carry out slip casting to the section of jurisdiction, top, use easy slip casting shelf, there are a lot of potential safety hazards in simple and easy shelf, and unstability causes casualty accident easily.
Therefore those skilled in the art is badly in need of a kind ofly can providing convenient, safe, equipment easily for secondary grouting.
Summary of the invention
The purpose of this utility model is according to above-mentioned the deficiencies in the prior art part, a kind of slip casting chassis for the secondary grouting operation is provided, this slip casting chassis connects as one by the running truck of some connection rod members with both sides, constitute transit passage therebetween, simultaneously at its running truck front end drawbar member is set, to reach while tunnel secondary grouting and not influence the purpose that electric locomotive passes through.
The utility model purpose realizes being finished by following technical scheme:
A kind of slip casting chassis for the secondary grouting operation, after described slip casting chassis is connected in shield machine final section vehicle frame, it is characterized in that described slip casting chassis comprises two cover running truck and some connection rod members, fixedlys connected with the described running truck top that is positioned at its both sides respectively in described connection rod member two ends.
Be provided with slurry filling machine, agitator, cement and water glass in the described running truck.
Described running truck is the double-layer frame structure.
Connection rod member length between the described two cover running trucks is not less than current electric locomotive width wherein.
The front end of described running truck is hinged with drawbar member.
The utility model has the advantages that, this slip casting chassis can be followed shield machine and be advanced, do not influence the tunneling construction of shield machine, improved the promptness of secondary grouting in the tunnel, saved the slip casting time greatly, and can not influence the current of electric haulage locomotive, allowed the slip casting operation become succinct convenient, guarantee ground settlement in controlled range, ensured the safety of surface buildings and pipeline.
Description of drawings
Fig. 1 is vertical view of the present utility model;
Fig. 2 is elevational schematic view of the present utility model;
Fig. 3 is lateral view of the present utility model;
Fig. 4 is the connection rod member partial enlarged drawing I among Fig. 1 in the utility model;
Fig. 5 is the drawbar member partial enlarged drawing II among Fig. 3 in the utility model.
The specific embodiment
Feature of the present utility model and other correlated characteristic are described in further detail by embodiment below in conjunction with accompanying drawing, so that technician's of the same trade understanding:
As Fig. 1-5, mark 1-16 is respectively among the figure: tunnel 1, water glass 2, running truck 3, slurry filling machine 4, agitator 5, connection rod member 6, cement 7, drawbar member 8, travelling wheel 9, trolley track 10, motorcycle track 11, reinforcing rib 12, billet 13, bolt 14, articulated stand 15, nut 16.
Embodiment: in certain construction of tunnel, the residing soil layer property in tunnel is poor, the water content height, and hydraulic pressure is big, and is totally unfavorable to the control ground settlement, so need often carry out secondary grouting with the control ground settlement in work progress.
As Figure 1-3, for strengthening the promptness of secondary grouting, reduce slip casting personnel's operation intensity, improve the safety of slip casting operation, the time that minimizing causes shield machine to stop to tunnel because of secondary grouting connects a slip casting chassis behind shield machine final section vehicle frame, this slip casting chassis is followed shield machine and advanced, can carry out secondary grouting whenever and wherever possible, save the time of transporting equipment back and forth.This slip casting chassis constitutes with some rod members 6 that are connected by being positioned at the cover of two on the trolley track 10 running truck 3, fixedly connected with the running truck 3 that is positioned at its both sides respectively in the two ends that connect rod member 6, connect the length of rod member 6 greater than the electric locomotive width of traveling on motorcycle track 11, guarantee that electric locomotive can have free passage between two running trucks 3; Running truck 3 adopts the double-layer frame structure, is provided with slurry filling machine 4, cement 7, agitator 5 and water glass 2 thereon, so that the slip casting chassis can carry out secondary grouting at any time.
Shown in Fig. 1,2 and 4, connecting rod member 6 is specially with fixed structure between the running truck 3: vertical being fixedly welded on the billet 13 in end that will be connected rod member 6, at connection rod member 6 and billet 13 reinforcing rib 12 is set simultaneously, to increase stability of structure, will connect rod member 6 afterwards and fixedly connected with running truck 3 by nut together with billet 13.
Shown in Fig. 1,3 and 5, running truck 3 is hinged by drawbar member 8 and shield machine final section vehicle frame, and the front end of running truck 3 fixedly has articulated stand 15, and the two ends of drawbar member 8 are hinged with articulated stand 15 by bolt 14.
Use this novel slurry filling chassis to carry out secondary grouting, saved the slip casting time widely, reduced the manpower consumption, allow the slip casting operation become succinct and make things convenient for, guaranteed that ground settlement is in controlled range, ensured the safety of surface buildings and pipeline, for the project engineering has obtained good economic benefit and social benefit.
