Specific embodiment
In order to be more clearly understood to the technical characteristic of the present invention, purpose and effect, now comparison accompanying drawing describes in detail
The specific embodiment of the present invention.
As Figure 1-3, the method for retaining wall rapid construction of the present invention comprises the following steps:
S1, set up scaffold, then supporting module 1；
S2, fix multiple Grouting Pipe 3 between template 1, spilled water hole is arranged on template 1.Grouting Pipe 3 is slip casting flexible pipe,
Its surface is provided with multiple slurry outlets 5, and many Grouting Pipe 3 are in that plum blossom-shaped arranges, and the arrangement pitch of Grouting Pipe 3 is not more than retaining wall height
2/3rds of degree are it is ensured that the speed of slip casting and uniformity.
S3, insert block stone 2 into template 1, block stone 2 diameter is not more than the half of width in template 1 space, and block stone 2 should
This has certain level and joins, and makes block stone intermediate gap less, can reduce grouting amount further.
S4, by Grouting Pipe 3 inject concrete grout stone filling 1 between space；
After the completion of s5, slip casting, carry out health preserving；
S6, form removal；
S7, whole retaining wall face is carried out repair, ditch baste or increase external decoration.
As shown in Figures 4 and 5, during construction, can adopt and with the following method retaining wall be reinforced.
The step of the retaining wall reinforcement construction method that the present embodiment provides is as follows:
1), cross rib 64 and perpendicular rib 63 are sequentially set in retaining wall lateral surface, and place sleeve pipe 62 at perpendicular rib 63 so that being somebody's turn to do
Sleeve pipe 62 is located in cross rib 64 and perpendicular rib 63, and one end is pressed on retaining wall lateral surface, and the other end extends out to outside perpendicular rib
Surface, has hollow structure in this sleeve pipe 62；Sleeve pipe 62 can propped up between gear template 1 and original soil mould with pre-plugged.
2), utilize jumbolter, by the hollow structure of sleeve pipe 62 in retaining wall pore-forming, continue in wall through after body of wall
Hole in the soil body afterwards, the bolthole that can be passed through for anchor pole 65 with formation and connect with the hollow structure in sleeve pipe 62；
3) in bolthole, insert anchor pole 65 muscle body, muscle body revealed section exposes to beyond perpendicular rib 63, and one end of anchor pole 65 is put
In bolthole, the other end passes through the hollow structure of sleeve pipe 62, extends to outside perpendicular rib 63；
4), inject cement mortar in bolthole, after maintenance expires, after that is, cement mortar reaches design strength, to anchor pole
65 carry out prestressed stretch-draw and are locked on perpendicular rib 63.
By above four steps, complete the operation of arrangement cross rib 64, perpendicular rib 63 and anchor pole 65 on retaining wall, gear soil
Under the compressing of cross rib 64 and perpendicular rib 63, ruggedized construction is securely attached together wall with retaining wall, cross rib 64 and perpendicular rib 63
Ensure retaining wall will not tympanites and fall block, the anchor force of anchor pole 65 passes through cross rib 64 and perpendicular rib 63 increased the antidumping of retaining wall
Moment is it is ensured that retaining wall will not sliding or topple, thus realizing the reinforcing of retaining wall.
Due to, in above-mentioned construction method, sequentially cross rib 64 and perpendicular rib 63 being poured on retaining wall lateral surface first, and
And in this process, be provided with, in cross rib 64 and perpendicular rib 63, the sleeve pipe 62 running through cross rib 64 and perpendicular rib 63, in sleeve pipe 62, have hollow
Structure, so, in subsequent operation, using jumbolter 17 by the hollow structure in sleeve pipe 62 ground after retaining wall and wall
Hole in body.Due to there being the protective effect of cross rib 64 and perpendicular rib 63, during boring, retaining wall will not be damaged, not result in drill hole gear
The large area of cob wall slabstone drops, and especially when repeatedly being holed, will not destroy the globality of retaining wall, preferably protect
Former retaining wall, thus can avoid retaining wall to cave in work progress.
Many times, in order to ensure the steadiness that cross rib 64 is connected with retaining wall lateral surface, in above-mentioned steps 1) in pour
Before cross rib 64, need the lateral surface of retaining wall is cleared up, manner of cleaning up can variation.
In above-mentioned construction method step 4) in, after anchor pole 65 carries out prestressed stretch-draw, the other end of anchor pole 65 is exposed at
Outside perpendicular rib 63, as such, it is possible to pour sealing off and covering anchorage body 66 on the outer surface of perpendicular rib 63, expose outside outside perpendicular rib 63 for wrapping up anchor pole 65
The other end on surface, prevents anchor pole 65 to be corroded.
According to above-mentioned construction method, the present embodiment additionally provides retaining wall reinforcement structure 6, specific as follows:
This ruggedized construction 6 includes the cross rib 64 being sequentially cast on retaining wall lateral surface and perpendicular rib 63, sets in retaining wall
Have in bolthole, cross rib 64 and perpendicular rib and be equipped with sleeve pipe 62, in sleeve pipe 62, there is hollow structure, this hollow structure connects retaining wall
In anchor pole 65 hollow structure run through perpendicular rib, panel and retaining wall that is to say, that hollow structure and bolthole form one
Hole position, is equipped with anchor pole 65 in the hollow structure of sleeve pipe 62, one end of anchor pole 65 is placed in the bolthole of retaining wall, and the other end is put
In the hollow structure through sleeve pipe 62, it is placed in outside perpendicular rib 63.
So, using above-mentioned ruggedized construction 6, so that retaining wall is effectively reinforced, prevent retaining wall from drum occurring
Swollen, ftracture and phenomenon of toppling.
So that cross rib 64 can preferably be pressed on retaining wall, retaining wall is played with reinforcement effect, cross rib 64 pours
Build on the lateral surface of retaining wall, and be in the skewed setting to inside retaining wall, so, the moment that cross rib 64 self gravitation produces
Act on retaining wall, retaining wall is played with the relatively firm effect reinforced.
Same reason, perpendicular rib 63 is cast on cross rib 64 outer surface, and is in the skewed setting to inside retaining wall.
In order to preferably support perpendicular rib 63, along retaining wall lateral surface lower end bearing of trend, perpendicular rib 63 lower end is provided with grade beam 61.
After anchor pole 65 carries out prestressed stretch-draw locking, the other end of anchor pole 65 is exposed at outside perpendicular rib 63, so, in order to protect
Shield anchor pole 65, pours sealing off and covering anchorage body 66 on the outer surface of perpendicular rib 63, and its parcel anchor pole 65 exposes outside the another of perpendicular rib 63 outer surface
End.
Above in conjunction with accompanying drawing, embodiments of the invention are described, but the invention is not limited in above-mentioned concrete
Embodiment, above-mentioned specific embodiment is only schematically, rather than restricted, those of ordinary skill in the art
Under the enlightenment of the present invention, in the case of without departing from present inventive concept and scope of the claimed protection, also can make a lot
Form, these belong within the protection of the present invention.
