In the present embodiment, concrete annexation between elastic pad 3, tube connector 4, band wire connection 5, the Grouting Pipe 6 is: the lower end outer wall of elastic pad 3 and the upper end inwall of tube connector 4 are by being threaded, the upper end outer wall of the lower end inwall of tube connector 4 and band wire connection 5 is by being threaded, and the lower end inwall of band wire connection 5 and the upper end outer wall of Grouting Pipe 6 are by being threaded.
The concrete mounting method of spring 7 is as follows: the top of spring 7 is fixedly connected with packing ring 8, be installed with the positioning component of holding packing ring 8 on the lower surface of lining trolley panel 1, the bottom of spring 7 is fixedly connected with nut 9, and the outer wall of nut 9 and Grouting Pipe 6 is by being threaded.
Positioning component comprises junction plate 10, steel plate latch 11, two reinforcing bar latches 12, draw-in groove 13, and junction plate 10 and draw-in groove 13 all are fixedly mounted on the lower surface of lining trolley panel 1, and junction plate 10 and draw-in groove 13 lay respectively at the relative both sides of packing ring 8; One side of steel plate latch 11 has notch 14, corresponding another side is provided with lug 15; Steel plate latch 11 is installed between the lower surface and packing ring 8 of lining trolley panel 1, and an end of steel plate latch 11 band lugs 15 is fixed in the draw-in groove 13, the end of steel plate latch 11 trough of belt mouths 14 is fixed between the lower surface of junction plate 10 and lining trolley panel 1, and Grouting Pipe 6 holdings are in the notch 14 of steel plate latch 11; Two reinforcing bar latches 12 are fixed between lug 15 and the junction plate 10, and packing ring 8 holdings are between reinforcing bar latch 12 and steel plate latch 11.The lower end of junction plate 10 is provided with the guide strip 17 of tape guide groove 16, and the lower end of Grouting Pipe 6 is passed gathering sill 16 backs and extended downwards, and guide strip 17 is positioned at the below of spring 7.
Install for convenient, offer the big hole 18 and the small sircle hole 19 that are interconnected on the lining trolley panel 1, Grouting Pipe 6 runs through lining trolley panel 1 by small sircle hole 19.Steel plate latch 11 in the positioning component also has the effect of coverings, sealing big hole 18 and partly not covered small sircle hole 19 of living except fixing Grouting Pipe 6.
In the present embodiment, elastic pad 3 is bowl-shape, is preferably rubber cup; Tube connector 4 is a pvc pipe, and band wire connection 5 is with the wire connection head for PVC.
Concrete mounting method of the present utility model is as follows:
Above-mentioned fastener inserts is inserted in two linings by the big hole on the lining trolley panel 1 18, made elastic pad 3 hold out against splash guard, vertical traversing to small sircle hole 19.
Insert steel plate latch 11, fixedly Grouting Pipe 6.One end of steel plate latch 11 band lugs 15 is fixed in the draw-in groove 13, the end of steel plate latch 11 trough of belt mouths 14 is folded in that (junction plate 10 upper surfaces offer two breach 20 between the lower surface of junction plate 10 and lining trolley panel 1, form groove between the lower surface of breach 20 and lining trolley panel 1, the end of steel plate latch 11 trough of belt mouths 14 then is plugged in the groove).
Insert reinforcing bar latch 12, retaining washer 8, with packing ring 8 holdings between reinforcing bar latch 12 and steel plate latch 11.Offer on lug 15 and the junction plate 10 and specialize in the through hole that reinforcing bar latch 12 wears usefulness.
After the utility model installs, in the process of concrete perfusion, during two lining chassis come-ups, packing ring 8 upwards can be drawn, make that spring 7 is further stretched, in the process that spring 7 is further stretched, nut 9 can drive upwards top of Grouting Pipe 6, makes elastic pad 3 all the more hold out against splash guard at last.Two lining chassis sink when binding, though packing ring 8 can be pressed down, reduced the stretch range of spring 7, but spring 7 be in all the time be subjected to extended state (because the stretch range that reduces all the time less than spring 7 original be subjected to stretch range), therefore can guarantee between elastic pad 3 and the splash guard closely connectedly all the time, guarantee that cement paste does not pour in the Grouting Pipe 6.When two lining chassis come-ups or the domains of walker of sinking have exceeded scope of design, so only need to increase the height of junction plate 10, change long spring 7 and get final product.
Behind the concrete initial set before the final set (concrete final set grouting behind shaft or drift lining pipe 6 back-out difficulty), pull out reinforcing bar latch 12, pull out steel plate latch 11, Grouting Pipe 6 is back-outed.Arrive this, the pre-buried success of pre-buried guard system, pre-buried band wire connection 5 has internal thread, and later stage Grouting Pipe 6 can be screwed into, the effective connection when guaranteeing slip casting.
If the various factors in the concreting process causes the lining cutting hogback to have the phenomenon of coming to nothing, grouting pressure can be washed rubber cup open, makes cement paste fill up the space.Because rubber cup has elasticity, can make cement paste be pressed into two from Grouting Pipe normally during the hogback mud jacking and serve as a contrast the position of coming to nothing.
Adopt the utility model Tunnel Second Lining hogback to reserve the Grouting Pipe system, effectively solved cement paste plugging problem, more can effectively guarantee the function of use of pre-pipe laying.The most of GB accessory that adopts of native system, it is convenient to buy, other handling eases, the native system applicability is strong, and any type of tunnel double-lining all is suitable for, and only needs to change the length of tube connector 4.Positioning component recycles, and the life-span is long, low price, and a cover is no more than 100 yuan; Fastener inserts cheap (3 yuan of less thaies) can be saved cost 75%.Native system is easy for installation, pre-pipe laying set-up time less than 5 minutes.
The utility model is applicable to the pre-buried Grouting Pipe of any type of secondary lining, only needs to get final product according to the tube connector 4 of different lining thickness intercepting appropriate length.
The foregoing description only is used to the inventive concept of the present utility model of explaining, but not to the qualification of the utility model rights protection, allly utilizes this design that the utility model is carried out the change of unsubstantiality, all should fall into protection domain of the present utility model.
