Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
Embodiment：As shown in figure 1, a kind of construction of soil-nailed wall structure, including base soil layer 9, it is arranged on the outer surface of base soil layer 9
Steel wire 6 and the steel pipe that is inserted in base soil layer 9.One end that steel pipe is inserted in base soil layer is fixedly connected with tapered steel point
First 3, and pipe shaft welding anti-back leg, anti-back leg is Ribbed Bar, and the other end then exposes to be connected outside base soil layer 9 with steel wire 6,
Steel wire 6 is laid on the outer surface of base soil layer 9.
As shown in Figure 2 and Figure 3, from φ 50mm steel pipes 1, the wall thickness 3.00mm of φ 50mm steel pipes 1, in φ 50mm steel pipes one end
Tapered steel tip 3 is welded, and opens up diameter 5mm pulp by quincuncial arrangement, every 300mm on the circumference of φ 50mm steel pipes 1
Hole 2.Because traditional soil nailing can not be in the normal pore-forming of closely knit boulder bed, so using φ 50mm steel pipes 1, being welded on φ 50mm steel pipes 1
The firm tip 3 of taper connect is and the plum blossom on φ 50mm steel pipes 1 in order to preferably make φ 50mm steel pipes 1 insert in closely knit boulder bed
The grout outlet 2 of shape arrangement is, because quincuncial arrangement serves drawknot effect, to increase globality, and can uniform pulp.According to going out
The quantity in slurry hole 2 such as weld at the Ribbed Bar of quantity at pipe outer wall, and Ribbed Bar includes the first φ 12mm Ribbed Bars 4, the
The 2nd φ 12mm Ribbed Bars 5 that one φ 12mm Ribbed Bars 4 are welded away from the one end of tapered steel tip 3（One can be also used herein
Ribbed Bar is integrally formed）, and four hangnails 8 are welded in the outer end of φ 50mm steel pipes 1.The outer wall of φ 50mm steel pipes 1 is close to pulp
Welded in the first φ 12mm Ribbed Bars 4 and the first φ 12mm Ribbed Bars 4 that hole 2 is welded with it into the of 160 degree of angles
Two φ 12mm Ribbed Bars 5 are in order to be able to making φ 50mm steel pipes 1 be anchored in boulder bed.In toward φ 50mm steel pipes 1 during slip casting, slurry
Liquid can be flowed in the first φ 12mm Ribbed Bars 4 and the 2nd φ 12mm Ribbed Bars 5 from grout outlet 2, some slurry stream
Enter into boulder bed, after after slurries condensation, form anchoring.By the first φ 12mm Ribbed Bars 4 and the 2nd φ 12mm band rib steels
Muscle 5 realizes the effect instead of traditional soil nailing tension with the frictional force that slurries and closely knit boulder bed are produced.Lay steel in soil layer surface
Silk screen 6, steel wire 6 is provided with retainer ring 7, and φ 50mm steel pipes 1 are squeezed into soil through retainer ring 7.In the prior art, soil nail wall is applied
Work, it is necessary to spread grid, the soil nailing stayed in outside soil layer is fixed, then fill-before-fire concrete surface after soil nailing insertion soil layer
Plate, and prior art typically first measures spacing and the position of soil nailing, then squeezes into soil nailing, re-lays bar-mat reinforcement.Due to surveying
Spacing and the position for measuring soil nailing are both time-consuming by looking for position to set soil nailing again, and produce mistake when easily squeezing into soil nailing again
Difference, so we are provided with steel wire 6, is provided with solid on steel wire 6 by the soil nailing position measured in advance by the position of soil nailing
Determine ring 7.When needing to carry out construction of soil-nailed wall, position and the spacing of φ 50mm steel pipes 1 are first measured, then will be needed on steel wire 6
The position for squeezing into φ 50mm steel pipes 1 is welded and fixed ring 7, then steel wire 6 is layered on soil layer, and surrounding has with riveting fixes, φ
50mm steel pipes 1 squeeze into soil layer according to the position of retainer ring 7.In view of the stability of steel wire 6, φ 50mm steel pipes 1 are exposed at soil
Four hangnails 8 are welded in one end outside layer, so effectively limit dropping for steel wire 6, and it is φ that hangnail 8, which is inserted in soil,
50mm steel pipes 1 provide tensile capacity.This structure is simple in construction, easy to operate, and cost is low, and stability is high, safe, construction speed
Degree is fast.
During installation, first tapered steel tip 3 will be welded on φ 50mm steel pipes 1, then apart from the about 300mm of tapered steel tip 3
First diameter 3.00mm slurry outlet 2 is got at place, is punched according still further to spacing 300mm.Then by the first φ 12mm Ribbed Bars 4
It is close to the welding, then the 2nd φ 12mm Ribbed Bars 5 are welded in the first φ 12mm Ribbed Bars 4 nearby of each slurry outlet 2,
Weld four hangnails 8 in the end of φ 50mm steel pipes 1.The spacing of φ 50mm steel pipes 1, and record position are measured, steel wire is layered on soil
On layer, ring 7 is welded and fixed according to the position of the φ 50mm steel pipes 1 of record.In use, steel wire 6 is completed according to predeterminated position,
Surrounding riveting tool is fixed, and the tapered steel tip 3 on φ 50mm steel pipes 1 is aligned into retainer ring 7, using jump bit by φ 50mm steel
Pipe 1 hammers boulder bed, then slip casting, gunite concrete panel.
