Description
Technical field
The present invention relates to a kind of forced miniature steel pipe pile-anchor cable joint soil-slope supporting construction and construction methods.
Background technique
In recent years, miniature steel pipe pile is used widely in the support reinforcement of soil-slope, in work progress, is adopted first
With drill hole of drilling machine, steel-pipe pile and cement injection mortar are then transferred.Bore operation in the engineering method is more time-consuming, is not appropriate for fast
Fast reinforcement for rushing danger engineering；And since stake diameter is smaller, the skid resistance that single steel-pipe pile can be provided is limited, common because of antiskid in engineering
Power is insufficient and the phenomenon that cause steel-pipe pile to fracture or pushed over.
Summary of the invention
Speed of application existing for existing miniature steel pipe pile supporting construction is excessively slow and the hypodynamic problem of single pile antiskid to alleviate,
The invention proposes a kind of forced miniature steel pipe pile-anchor cable joint soil-slope supporting construction and construction methods.Pass through static pressure
Miniature steel pipe pile is pressed into rapidly in soil by method, to play the role of that side slope is inhibited to continue sliding；Then, construction stake apical cap beam,
To enhance the globality of supporting construction；After crown beam intensity reaches requirement, adjacent steel-pipe pile middle position construct one of anchor cable,
And by the locking of rope head in crown beam, to form steel-pipe pile-Application of Combined Support with Anchor structure.
The technical solution adopted by the present invention to solve the technical problems is:
A kind of forced miniature steel pipe pile-anchor cable joint soil-slope supporting construction, including several miniature steel pipe piles, stake top
Crown beam and anchor cable, each miniature steel pipe pile by static pressure method indentation soil in, and the stake end of miniature steel pipe pile protrude into sliding surface hereinafter,
And stake top is higher by earth's surface setting；
With in row's miniature steel pipe pile, the stake top of each miniature steel pipe pile is linked into an integrated entity by same root stake top crown beam；And it is same
It arranges in miniature steel pipe pile, is arranged with an anchor cable between adjacent two miniature steel pipe piles；
The anchoring section of anchor cable is located at sliding surface hereinafter, and the rope head of anchor cable then locks with stake top crown beam.
Further, after the rope head of the anchor cable passes through stake top crown beam, locked by lock solid structure and stake top crown beam.
Further, each anchor cable is in the middle position of adjacent two miniature tubular poles.
Another technical object of the present invention is to provide a kind of forced miniature steel pipe pile-anchor cables to combine soil-slope supporting knot
The construction method of structure, comprising the following steps:
Firstly, in the region for needing rapid rescue to reinforce, several row's miniature steel pipe piles of being constructed rapidly using static pressure method, with suppression
The further sliding of side slope processed；When construction, sliding surface is protruded into hereinafter, and stake top is higher by earth's surface in row's miniature steel pipe pile stake end
Setting；Then, stake top crown beam is poured, entirety will be linked to be with row's miniature steel pipe pile；Finally, reaching requirement to stake top crown beam intensity
Afterwards, in one of anchor cable of adjacent miniature steel pipe pile middle position construction, and by the locking of the rope head of anchor cable in stake top crown beam, and anchor cable
Anchoring section be located at sliding surface hereinafter, to form steel-pipe pile-Application of Combined Support with Anchor structure.
Further, after the rope head of the anchor cable passes through stake top crown beam, locked by lock solid structure and stake top crown beam.
The beneficial effects of the present invention are: quickly completing the construction of miniature steel pipe pile by static pressure method, it is able to suppress slight slope
Further sliding；Miniature steel pipe pile-Application of Combined Support with Anchor structure can significantly improve skid resistance, enhance consolidation effect.
