Referring to figure 5 and figure 6, bottom nozzle mounts 23 include fixed bottom plate 231 and the fixed anchor for being inserted into bottom of foundation ditch soil
Gu column 232,23 inner vertical of bottom nozzle mounts offers the slot 233 of grafting piling bar 21, and the size of slot 233 is greater than piling bar
21 sizes enable piling bar 21 to slide in slot 233.Unstable, slot 233 when to avoid piling bar 21 with 233 grafting of slot
Jack 235 is offered towards the side of foundation pit side-wall, 21 bottom end of piling bar corresponds to jack 235 equipped with holdfast 211；When 21 grafting of piling bar
After in slot 233, piling bar 21 is pushed to make holdfast 211 and 235 grafting of jack towards foundation pit inner sidewall one end, so that steel
Connection is more stable when stake 21 is plugged into slot 233.
Referring to Fig. 4 and Fig. 5, for the stability for guaranteeing piling bar 21, the lower end of piling bar 21 is fixedly connected with connecting plate 24, to protect
Card bottom nozzle mounts 23 can play the role of supporting & stablizing to piling bar 21, and connecting plate 24 is fixedly connected with fixed bottom plate 231, fixed
Bottom plate 231 is equipped with fixation hole 234 vertically, and fixation hole 234 is threaded with fixing bolt 236；For convenience of fixing bolt 236 and fixation hole
234 alignments, the corresponding fixation hole 234 of connecting plate 24 offer the square hole 241 being connected with fixation hole 234, and fixing bolt 236 passes through
Square hole 241 is threadedly coupled with fixation hole 234 so that piling bar 21 is fixedly connected with bottom nozzle mounts 23.Fixed bottom plate 231 deviates from
One end of foundation pit side-wall is rotatablely hinged with diagonal brace 25, and one end rotation that diagonal brace 25 deviates from fixed bottom plate 231 is equipped with fixed feet 251,
Fixed feet 251 is fixedly connected with piling bar 21；Enhance the bonding strength of piling bar 21 and bottom nozzle mounts 23 by diagonal brace 25.Fixed feet
251 are circumferentially with multiple through holes 252 for being axially parallel to 251 axis of fixed feet along it, are equipped with screw rod in through hole 252
253, fixed feet 251 is fixedly connected by screw rod 253 with piling bar 21.
Referring to Fig. 4 and Fig. 6, horizontal support piece 26 includes and the fixed support leg 261 contradicted of two sides piling bar 21 and connect two
The support rod 262 of a support leg 261, support leg 261 are fixedly connected in Y-shaped and both ends with adjacent two piling bars 21, increase branch
Support foot 261 improves the stability that support leg 261 is connect with piling bar 21 with the contact area of piling bar 21 simultaneously.The two of support rod 262
End outside screw is connected with sleeve 263, and support leg 261 is equipped with external screw thread 2611, sleeve 263 and outer spiral shell away from one end of piling bar 21
Line 2611 is threadedly coupled and the thread rotary orientation at the both ends of sleeve 263 is opposite；For convenience of the rotation of sleeve 263,263 lateral wall of sleeve
It is opposite to be equipped with handle 2631.By the threaded connection of external screw thread 2611 and sleeve 263 so that support leg 261 and support rod 262 it
Between connection it is more stable, simultaneously because the thread rotary orientation at 263 both ends of sleeve is suitable, rotating handles 2631 make support rod 262
It is relatively or contrarily moved with support leg 261, to be adjusted to the spacing between support leg 261 and support rod 262.
Referring to Fig. 6, for the bonding strength for guaranteeing piling bar 21 and steel plate 22, the two sides of piling bar 21 offer card slot 212 vertically
And the section of card slot 212 is L-shaped, the two sides of steel plate 22 and card slot 212 are clamped.The section of steel plate 22 is U-shaped, when soil avalanche
When steel plate 22 pressure being subject to can be transmitted to two sides, the pressure being subject to steel plate 22 disperses, and avoids single or muti-piece
22 stress of steel plate is excessive and the stability for going along with sb. to guard him component 2 is reduced.The disassembly of component 2 is gone along with sb. to guard him for convenience of the later period, steel plate 22
Both ends are equipped with the first blocked hole 221, and piling bar 21 offers the second blocked hole 213 away from one end of connecting plate 24, when needing to dismantle
Steel plate 22 and piling bar 21 are extracted out of foundation pit with the second blocked hole 213 by the first blocked hole 221.
Specific implementation process: after excavation of foundation pit is completed, by successively striking the interconnecting piece of steel column 12 and arc-shaped angle steel 11
Enter the soil of bottom of foundation ditch, then stretches earth-retaining net 13 along foundation pit inner sidewall, and the both ends of earth-retaining net 13 are passed through into clamping plate 14
It is fixed with arc-shaped angle steel 11.After earth-retaining component 1 is installed, the soil of foundation pit side-wall is tentatively protected, then successively will
Bottom nozzle mounts 23 knock in the soil of bottom of foundation ditch, then piling bar 21 is successively plugged into slot 233 and piling bar 21 is pushed to make
Holdfast 211 and 235 grafting of jack avoid piling bar 21 from shifting in slot 233 inclination.
Then horizontal support piece 26 is installed, it is first that the both ends of one of support leg 261 and two neighboring piling bar 21 are fixed,
Yet another support leg 261 is fixedly connected by sleeve 263 with support rod 262, then makes support rod 262 by sleeve 263
The other end be fixedly connected with support leg 261, last swing handle 2631 increases the spacing of support rod 262 and support leg 261
Greatly, so that fixed 21 side wall of piling bar contradicted of horizontal support piece 26, the upper end for piling bar 21 provides support force.
Since the size of slot 233 is greater than the size of piling bar 21, piling bar 21 is in slot under the conflict of horizontal support piece 26
It is moved in 233, so that fixation hole 234 is connected with square hole 241, pushes the piling bar not connecting with horizontal support piece 26
21, but also fixation hole 234 is connected with square hole 241, fixed bottom plate 231 and connecting plate are then made by fixing bolt 236
24 are fixedly connected.Rotation diagonal brace 25 is fixedly connected with fixed feet 251 with piling bar 21 by screw rod 253, enhances piling bar 21 and bottom
The stability that portion's fixing piece 23 connects, avoid piling bar 21 and steel plate 22 are subject to when soil avalanche pressure excessive so that piling bar 21 with
Shearing force is formed between bottom nozzle mounts 23.Finally 22 two sides of steel plate are corresponded to card slot 212 and are inserted downwardly into card slot 212 and are made
Steel plate 22 and card slot 212 are clamped, and make the protrusion of steel plate 22 towards foundation pit inside, are passed so that decomposing power when 22 stress of steel plate
It is delivered to two sides.
In the construction process, when the building of construction constantly builds rising, according to the process of construction to horizontal support piece
26 are dismantled.After the completion of construction, when needing to dismantle support construction, steel plate 22 is pulled up by the first blocked hole 221, is made
Steel plate 22 is obtained to be detached from out of card slot 212；Since the bottom of piling bar 21 is fixedly connected with bottom nozzle mounts 23, pass through the second blocked hole
213 pull up piling bar 21, so that piling bar 21 and bottom nozzle mounts 23 are detached from inside foundation pit.It is completed when going along with sb. to guard him the disassembly of component 2
Afterwards, the gap between building and earth-retaining component 1 increases, and makes clamping plate 14 and arc-shaped angle steel 11 by manually unscrewing bolt 112
It separates and earth-retaining net 13 is detached from out of arc-shaped angle steel 11, after the winding of earth-retaining net 13 is taken out, by arc-shaped angle steel 11 and steel column
12 extract from foundation pit；To realize the dismounting of support construction and be recycled.
The embodiment of present embodiment is the preferred embodiment of the utility model, and not limitation is originally practical new according to this
The protection scope of type, therefore: the equivalence changes that all structures, shape, principle according to the utility model are done should all be covered by practical
Within novel protection scope.
