Description
Technical field
The utility model belongs to field of civil engineering, and in particular to a kind of steel tube for soil-nail construction conveyer.
Background technology
The development of urban construction is usually from inner city to extending around.To make full use of soil, it is necessary to existing
Or built in the rubbish landfill of early stage planning various buildings or build highway, the infrastructure such as railway.Therefore, permitted at present
Many new constructions can run into the problem of miscellaneous fill side slope pattern foundation pit supporting structure, be especially in the presence of the base pit engineering of deep miscellaneous fill.
Miscellaneous fill refers to the deposit produced due to mankind's activity, and its composition is general more mixed and disorderly, by gravelly soil, sand
The one or several kinds composition such as soil, cohesive soil, and containing debris such as building waste, industrial wastes, the characteristics of such is native is random
Accumulation, complicated component, space is big, loosely organized, lack of homogeneity, causes that soil body globality is poor, and soil shear strength is low, makes position
Base pit engineering danger in deep miscellaneous fill place is larger.
Because pore-forming difficulty is very limited, using the supporting side of slope plus steel tube for soil-nail combination compaction grouting technology
Method, in miscellaneous fill Foundation Pit Support Design with, using more, being more ripe processing scheme, effectively foundation ditch can be controlled to become in construction
Shape, it is ensured that the safety of foundation ditch and Underground Construction phase.Steel tube for soil-nail is constructed and the quality of grouting quality is to determine pattern foundation pit supporting structure
The key of success or failure.Traditional steel tube for soil-nail construction method, general to drive pneumatic hammer to be driven into using air compressor machine, low construction efficiency, difficulty
Greatly, cost is high, and does not much reach design length due to being limited by artificial strength, it is difficult to ensure construction quality.How to take
Effective measures improve the construction quality and reduction construction cost of steel tube for soil-nail, are the problem of solving at present.
The content of the invention
The purpose of this utility model is to provide a kind of steel tube for soil-nail construction conveyer, utilizes the hammer hammering of existing hook machine gun
Method, solves low construction efficiency in existing construction technology, it is necessary to manually more, the problem of construction cost is larger, and protecting
Card construction quality reaches technical requirements.
The purpose of this utility model is realized in the following manner：Steel tube for soil-nail construction conveyer, including it is enclosed on steel pipe soil
The sleeve that bell mouth shape is fixed with backing plate, backing plate, diameter of the sleeve close to backing plate side are fixed with the casing nailed on, casing
Less than the diameter away from backing plate side.
The casing is internally provided with pad, pad and pad contact.
The pad is timber or elastic composite.
The material of the casing, backing plate and sleeve is high-strength metal material or composite.
The thickness of the backing plate is 20mm.
The beneficial effects of the utility model are：The utility model sets up a conveyer on the top of steel tube for soil-nail, uses
During hammering construction, hammer force is directly acted on conveyer, is made active force is more uniform to act on steel tube for soil-nail top, is improved hammer
The action effect of power is hit, and protects steel tube for soil-nail top, is conducive to next step steel tube for soil-nail to weld, efficiency of construction is improved, in addition
In construction, required artificial quantity is reduced, and construction vertical height reduces the requirement to earth excavation up to 3~4m；Substantially reduction
Construction cost, this utility model patent also has the advantages that material is easy to get, working space is small, construction is simple, cheap.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is construction schematic diagram of the present utility model.
Embodiment
As shown in Figure 1 and Figure 2, it is solid on steel tube for soil-nail construction conveyer, including the casing 4 being enclosed on steel tube for soil-nail 8, casing 4
Surely there is backing plate 2, the thickness of backing plate 2 is the sleeve 1 that bell mouth shape is fixed with 20mm, backing plate 2, and sleeve 1 is close to the side of backing plate 2
Diameter is less than the diameter away from the side of backing plate 2, and casing 4 is internally provided with pad 3, and pad 3 is contacted with backing plate 2, and pad 3 is timber
Or elastic composite, the material of casing 4, backing plate 2 and sleeve 1 is high-strength metal material or composite, conveyer 5
The size dimension of casing 4 can be determined according to the size of steel tube for soil-nail diameter of steel tube.
The utility model sets up a conveyer 5 on the top of steel tube for soil-nail 8, while increasing a buffer plate 2 of pad 3
With the active force on the top of steel tube for soil-nail 8 so that active force more uniform distribution is on the top of steel tube for soil-nail 8；According to execution conditions and setting
Steel tube for soil-nail 8 is truncated into suitable length by meter scheme, and the length should meet the mechanical hammer force of the hammering used in construction and pass through
The perpendicular acting of conveyer 5 is at the top of steel tube for soil-nail 8；The weld strength of the different composition sections of steel tube for soil-nail 8 will meet design requirement；Apply
The hammering machinery 6 of work can also be used other simple, easy and be met execution conditions stamping machine using small-sized hook machine gun hammer
Tool.
The Specific construction process of steel tube for soil-nail construction conveyer of the present utility model is as follows：First by according to supporting scheme
It is required that, with reference to execution conditions it is up-to-standard prepare steel tube for soil-nail 8, steel tube for soil-nail 8 is truncated into n sections according to suitable length；Then
First paragraph steel tube for soil-nail 8 is hammered into miscellaneous fill side slope 7 according to design requirement, then second segment steel tube for soil-nail 8 is welded to
On first paragraph steel tube for soil-nail 8, continue to construct, construct and complete until whole steel tube for soil-nail 8.
