In), using soil nail wall or composite soil nailing wall is a kind of both economical supporting side as the support system of foundation ditch
Case.
At present, soil nailing wall structure of the prior art, the many employings of its soil nailing with injected hole steel pipe (or
Reinforcing bar), by (or in boring) slip casting in pipe, it is achieved the reinforcing to the foundation ditch surrounding soil body, foundation ditch slope
Face uses and hangs bar-mat reinforcement and spray concrete, makes the soil being reinforced and forms the compound soil body by the soil nailing of slip-crack surface,
Be equivalent to gravity retaining wall, thus reach the purpose of supporting foundation pit, but, this utilize steel pipe or reinforcing bar to make
For the soil nailing of material, because it is outside relatively smooth, and the frictional force produced between soil layer is less, therefore exists
During construction, its demand is relatively big, the quantities of this construction being increased by.
Utility model content
The purpose of this utility model is to provide a kind of foundation pit construction soil nailing, to solve common soil nailing and soil
The problem that between Ceng, frictional force is less.
For achieving the above object, this utility model following technical scheme of offer: a kind of foundation pit construction soil nailing,
Including tail pipe, fixture, middle pipe and head tube, threaded between described tail pipe and described middle pipe, described
Middle pipe is minimum is set to one, is threaded connection, described middle tube side between described middle pipe and described head tube
Wall is provided with perforate and locating part, is interconnected between described perforate and described locating part, described locating part
Inside is fixed with elastic component, and described elastic component is internally provided with extension, described fixture and described stretch
Go out portion's tail end to be slidably connected.
Preferably, described extension includes that newel post, foundation and base, described newel post and described foundation are one
Body structure, is enclosed with end shield outside described newel post, described end shield bottom outside is fixed with projection, described
Base and the fixing connection of described foundation, described base bottom is fixed with protective layer.
Preferably, described end shield is plastic construction, and described base end is set to trapezoidal, described protective layer
For ganoid rich chromium cast iron wearing layer.
Preferably, described fixture end is set to taper.
Technique effect of the present utility model and advantage: this foundation pit construction soil nailing, by installing varying number
Middle pipe can control the length of soil nailing, and be attached by screw thread between middle pipe and middle pipe, permissible
Easily dismantle, the soil nailing of different length can be installed according to different situations, and by stretching out
Portion can increase the frictional force between soil nailing and soil layer, such that it is able to reduce the consumption of soil nailing, reduces engineering
Amount, work when, is driven into fixture inside middle pipe, because fixture end is through tail pipe
Taper, it is possible to use extension is fixed on the position of work by fixture, needs are dismantled when, can
To be extracted by fixture, the end shield in fixture can be stuck in outside, and other portions due to the projection of bottom
Position can rely on the elasticity of elastic component to be retracted into predetermined position, and due to the existence of end shield, newel post retracts
Time, frictional force will not be produced with soil layer, thereby may be ensured that newel post can retract well, from
And can the most easily soil nailing be extracted.Therefore, this utility model is reasonable in design, it is ensured that soil nailing
And between soil layer, there is bigger frictional force, it is possible to reduce the consumption of soil nailing, and profit again can be reclaimed
With, economize on resources, very environmental protection.

Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, to the technology in this utility model embodiment
Scheme is clearly and completely described, it is clear that described embodiment is only this utility model one
Divide embodiment rather than whole embodiments.Based on the embodiment in this utility model, this area is common
The every other embodiment that technical staff is obtained under not making creative work premise, broadly falls into this
The scope of utility model protection.
This utility model provides a kind of foundation pit construction soil nailing as depicted in figs. 1 and 2, including tail pipe 1,
Fixture 2, middle pipe 6 and head tube 7, threaded between described tail pipe 1 and described middle pipe 6, described in
Pipe 6 is minimum is set to one, is threaded connection between described middle pipe 6 and described head tube 7, described in
Pipe 6 sidewall is provided with perforate 5 and locating part 8, is interconnected between described perforate 5 and described locating part 8,
Described locating part 8 is internal is fixed with elastic component 4, and described elastic component 4 is internally provided with extension 3, institute
State fixture 2 and described extension 3 tail end is slidably connected.
Further, described extension 3 includes newel post 31, foundation 34 and base 35, described newel post 31
It is structure as a whole with described foundation 34, outside described newel post 31, is enclosed with end shield 32, described end shield 32 end
Protruding 33 it are fixed with, described base 35 and the fixing connection of described foundation 34, described base 35 outside portion
Bottom is fixed with protective layer 36, and protective layer 36 can be that base 35 provides protection, extends it and uses the longevity
Life.
Further, described end shield 32 is plastic construction, and described base 35 end is set to trapezoidal, institute
Stating protective layer 36 is ganoid rich chromium cast iron wearing layer, and plastic construction has stronger corrosion resistance,
Can protect newel post 31, rich chromium cast iron has the strongest wearability, after this multiple use will not
Produce bigger abrasion, base 35 can be made to have longer service life.
