Detailed description of the invention
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. 1-9, in figure, mark 1-21 is respectively: shield machine 1, vehicle frame 2, slip casting chassis 3, synchronous grouting pipeline 4, tee junction 5, secondary grouting pipeline 6, water glass 7, running truck 8, slurry filling machine 9, agitator 10, connecting rod 11, cement 12, drawbar member 13, travelling wheel 14, trolley track 15, motorcycle track 16, reinforcing rib 17, metal mat 18, bolt 19, articulated stand 20, nut 21.
Embodiment: as shown in Figure 1, the present embodiment relates to a kind of combined type filling system, this combined type filling system is for shield method tunnel construction, and when shield machine covers building on passing through, it can effectively reduce shield structure and pass through the impact on above covering building.
As shown in Figure 1, the major function of this combined type filling system has 3 points, 1.: taking the synchronous grouting system in shield machine 1 as main, carry out synchronous grouting by its synchronous grouting pipeline 4; 2.: the synchronous grouting system on shield machine 1 is transformed, separated a road secondary grouting pipeline 6 from synchronous grouting pipeline 4 and carry out secondary grouting after wall; 3.: combined type filling system is connected with multi-functional slip casting chassis 3, on it, disposing secondary grouting equipment can carry out mending for the third time slurry, i.e. replacement grouting after follow-up wall.
As shown in Fig. 1-6, the above-mentioned functions of this combined type filling system is realized by following structure:
As shown in Figure 1, the front end of this combined type filling system is shield machine 1, and the rear of shield machine 1 is connected with some bogie frames 2, and the rear end of last bogie frame 2 is connected with slip casting chassis 3.In vehicle frame 2, be provided with conventional synchronous grouting pipeline 4, this synchronous grouting pipeline 4 is by connected grouting pump pumps water mud, in the front portion that is positioned at shield machine 1 rear first segment vehicle frame 2, on synchronous grouting pipeline 4, separate secondary grouting pipeline 6 by tee junction 5, and in this place, pressure meter and ball valve are set, to check the switching of grouting pressure and control secondary grouting pipeline 6.
As shown in Fig. 1-6, be connected to the facilities and equipments that sizing process is mended in slip casting chassis 3 conducts on final section shield structure vehicle frame 2 for the third time, for replacing former inert slurry (thick slurry).This slip casting chassis 3 forms by being positioned at the cover running truck 8 of two on trolley track 15 and some connecting rods 11, the two ends of connecting rod 11 are fixedly connected with the running truck 8 that is positioned at its both sides respectively, the length of connecting rod 11 is greater than the electric locomotive width of traveling on motorcycle track 16, guarantees that electric locomotive can have free passage between two running trucks 8; Running truck 8 adopts double-layer frame structure, is provided with slurry filling machine 9, cement 12, agitator 10 and water glass 7 thereon, so that slip casting chassis can carry out secondary grouting at any time.Fixed structure between connecting rod 11 and running truck 8 is specially: the end vertical welding of connecting rod 11 is fixed on billet 18, on connecting rod 11 and billet 18, reinforcing rib 17 is set simultaneously, to increase the stability of structure, afterwards connecting rod 11 is fixedly connected with running truck 8 by nut together with billet 18.Running truck 8 is hinged with the final section vehicle frame of shield machine 1 by drawbar member 13, and the front end of running truck 8 is fixed with articulated stand 21, and the two ends of drawbar member 13 are hinged with articulated stand 20 by bolt 19.This slip casting chassis is followed shield machine and is advanced, and can carry out secondary grouting whenever and wherever possible, has saved the time of Transporting equipment back and forth, and does not affect the current of electric haulage locomotive.
As shown in Fig. 1,7,8, the combined type filling system in the present embodiment has formed three multi-form grouting process of following different phase, specific as follows:
Being to utilize synchronous grouting pipeline 4 to carry out shield synchronization slip casting for the first time, is the basic of whole slip casting, and control range is 6 rings (being 0-7.2m after shield tail) after the tail of shield machine 1;
Slip casting for the second time utilizes secondary grouting pipeline 6 on the injected hole of section of jurisdiction, to supplement for the second time slip casting exactly, and control range is that after the tail of shield machine 1,6 rings to 12 ring scopes (are that 7.2-14.4 is m) after shield tail;
Be mainly to carry out slip casting for the deficiency of slip casting for the second time and the contraction of later stage slurries for the third time, i.e. replacement grouting, utilizes the grouting pipeline on slip casting chassis 3, adopts cement paste, replaces former inert slurry, and range of grouting is final section vehicle frame 2 front and back 50m.
As seen from Figure 8, the grouting method of this technique makes the scope of slip casting become continuity.In using old technology slip casting, the secondary grouting control range section in Fig. 8 cannot be carried out slip casting in time, and need just can obtain slip casting time waiting and arriving vehicle frame afterbody to section of jurisdiction, so, have approximately lagged behind in time 24 hours.While construction in the stratum of sedimentation sensitivity, when running into emergency situations and need secondary grouting in a hurry, be undoubtedly fatal the lag time of 24 hours, will on cover building and cause irreversible impact.And adopt this technique, can avoid the limitation of range of grouting and time.
Aspect external grouting pump benefit slurry, in old technology, have to adopt and set up movable simple and easy slip casting platform, this slip casting platform need be by artificial dilatory moving ahead, it is light and handy that this just causes platform to be particular about in design, cause its safety and stability lower, on platform, only can place a grouting pump, 2 workmans' slip casting space is provided.And in this technique, develop the slip casting vehicle frame of car-type, be connected to the final section of shield structure vehicle frame, slip casting trolley structure is stable, safe, can place respectively in both sides a grouting pump, the slurry filling machine cement injection of one side, the slurry filling machine water filling glass of opposite side, also can place slurry mixing tank and sufficiently long grouting pipeline on chassis, extended the control range of three slip castings, reduce in addition the number of workers of slip casting, improved safety and the simplicity of operation.
As shown in Figure 9, taking a certain engineering as example, the Ishikawa island earth pressure balanced shield that this project is Φ 6340mm by a diameter is constructed, central axis residing soil layer in tunnel is mainly 2 layers of grey sandy silt layer, 1 layer of taupe gray viscous soil horizon and 2 layers of grey grittiness silt, flour sand layer, soil layer property is poor, water content is high, and hydraulic pressure is large, totally unfavorable to controlling ground settlement.For improving the effect of slip casting, reduce slip casting personnel's operation intensity, improve the safety of slip casting operation, whole engineering has adopted the combined type filling system described in the present embodiment and corresponding grouting process thereof.The enforcement of new grouting process, produces a desired effect, and has effectively reduced the disturbance to earth's surface, makes shield machine pass through smoothly all kinds of buildings, within final be controlled at-20mm of building settlement, and maximum point position-19.1mm.Building does not have crack and door and window to close the quality problems that the sedimentation such as abnormal causes, tunnel quality is also good.As shown in figure line in Fig. 9, the combined type filling system in the present embodiment has guaranteed that ground settlement is in controlled range, has ensured the safety of surface buildings and pipeline, for projects has been obtained good economic benefit and social benefit.
