Abstract
The utility model relates to a backfilling grouting device capable of being recycled, which comprises a grouting pipe and a connecting pipe. A ball valve is arranged between the grouting pipe and the connecting pipe. One end of the connecting pipe is connected with a sleeve through a screw, a bulkhead nut, an extruding nut and a thrust bearing successively. A plurality of rubber rings are sleeved on the sleeve. The backfilling grouting device has the functions of: satisfying use requirement, saving cost through recycling, greatly improving construction efficiency, and simultaneously improving in-hole construction environment to a certain extent.
Description
Technical field
The utility model relates to underground structrue engineering field, relates in particular to a kind of backfill grouting device.
Background technology
Nearly ten years, domestic subway construction has entered the period of fast development.Each city underground line design of the whole nation is more and more, and Rail traffic network is day by day intensive, and subway line design is generally laid along major trunk roads, and circuit network will pass through the intensive place of passenger flow as far as possible, generally along business district or resident's close quarters plan.Due to surrounding enviroment restriction, at urban central zone, adopt hidden construction process construction more.Underground excavation can make around stratum and ground generation distortion, and severe patient can have influence on the normal use that closes on building construction and periphery pipeline.Because being out of shape, excessively cause house and line break, the engineering accident such as tilt, cave in happens occasionally.Therefore, the construction of solution subway engineering, especially in hidden construction process construction, the control of surrounding ground sedimentation has been become to the most important thing, controlling at present one of Stratum Loss and sedimentation effective method is exactly backfill grouting, and backfill grouting is also indispensable one section of operation in hidden construction process working procedure.So, how to carry out fast backfill grouting, guarantee that grouting quality is the important topic that tunneling construction risk is controlled.To the research of this problem, can not only effectively control construction risk, for improving construction efficiency, improve construction environment and be significant.
Tradition backfill grouting way is all must welding Grouting Pipe before each slip casting, after slip casting finishes, will cut off Grouting Pipe, welds and cut off minimum 30 minutes of the time of a Grouting Pipe, with 4 of welding rods, has taken a large amount of time and waste electricity, has strengthened cost; While reusing, owing to last time welding the existence of wound, caused very large difficulty to welding for the second time next time, and weld interval is long, and poor welding quality has extended the engineering time, has reduced efficiency of construction; Meanwhile, because construction space in hidden construction process engineering method condition restriction tunnel is narrow and small, this construction method must be used electric welding machine, makes job site more crowded, has increased potential safety hazard.
Utility model content
The purpose of this utility model is to provide a kind of backfill grouting device reusing, and with a kind of expansion type stop grouting plug that need not weld, substitutes the construction of traditional welding method grouting stop-valve.
The technical solution of the utility model is as follows: a kind of backfill grouting device reusing, comprise Grouting Pipe, tube connector, between Grouting Pipe and tube connector, be provided with ball valve, one end of tube connector is connected with a sleeve with thrust bearing by screw, plug nut, extruding nut successively, is arranged with a plurality of rubber rings on sleeve.
Further, wherein push nut both sides and be provided with wrench for steel tube;
Further, its middle sleeve, Grouting Pipe and tube connector adopt galvanized pipe to make.
Basic principle of the present utility model is to adopt sleeve extruding rubber ring, rubber ring is deformed, thereby be firmly stuck in concrete hole, connecting bolt connection grouting stop-valve for one end at stop grouting plug, when finishing, slip casting closes in time grouting stop-valve, after concrete initial set, loosening sleeve is removed stop grouting plug, removes pipe inner concrete.The main material that this backfill grouting device uses has: galvanized pipe, PVC rubber ring, nut.The design of this backfill grouting device and application have installs and uses quick, good leak tightness, easily changes and repair and save the advantages such as artificial and material cost.
The beneficial effects of the utility model are: the installation and removal time used of the backfill grouting device that can reuse is about 10 minutes, saved the plenty of time, also the smog not producing because of electric welding, improved construction environment, adopted the good rubber of durability degree, flexible can be closely connected with hole wall, be difficult for spillage and running pulp, the design of this slurry casting machine is a set of bolted assembly simultaneously, and local parts damages and wearing and tearing are convenient to change.Facts have proved, this backfill grouting apparatus is easy for installation, use is quick, reduces recruitment; Can recycle many times, save the materials such as pre-buried welded tube and welding rod, remarkable benefit, has good using value and dissemination.

Fig. 2 is a kind of backfill grouting device fundamental diagram reusing.
Description of reference numerals:
1. ball valve; 2. screw; 3. plug nut; 4. wrench for steel tube; 5. push nut; 6. rubber ring; 7. Grouting Pipe; 8. tube connector; 9. thrust bearing; 10. sleeve; 11. pads; 12. plug nuts; 13. concrete structures; 14. backfill slurries; 15. injected holes.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
1) its Specific construction process is as follows: utilize wrench for steel tube to insert in pre-plugged or the interim injected hole of opening the backfill grouting device processing, utilize sleeve extruding rubber ring, make rubber ring expand distortion, thereby be firmly stuck in concrete hole.Then the Grouting Pipe of backfill grouting device and slip casting machine pipes are connected firmly, after before slip casting, the connection of machine, pipeline being checked, open grouting stop-valve and carry out backfill grouting construction.When slip casting finishes, close in time grouting stop-valve, after concrete initial set, loosening sleeve is removed stop grouting plug, removes coagulation in pipe, carries out by that analogy next backfill grouting construction.
2) what this backfill grouting device rapidoprint adopted is Φ 25 (thick 3mm) galvanized pipe, external diameter Φ 46PVC rubber ring, the handled nut of internal diameter Φ 25 weldering, XC51105 type thrust bearing, Φ 32 pads, Φ 32 galvanized pipes, Φ 20 galvanized pipes, Φ 20 ball valves, Φ 25 nuts, above material is building site common materials, obtain easily, it is convenient to change, and concrete thin portion structure is shown in Fig. 1.Its cardinal principle is to connect with boltsly, simple to operate and be connected firmly, and concrete principle is shown in Fig. 2.Employing, after engineered fill slurry casting machine, has been saved the working time, has reduced labor strength, has improved operating efficiency, has reduced cost.The slip casting of each hole of stop grouting plug slip casting is saved 20 minutes, 4 of capable of saving welding rods, using electricity wisely, directly and indirect benefit all considerable.
