Abstract
The utility model discloses a kind of miniature steel pipe pile supporting construction of built-in profile steel, the Guan Liang through resting on the ground is attached between including at the top of multiple buried miniature steel pipe piles, adjacent 2 miniature steel pipe piles；The miniature steel pipe pile, which includes, has been put into reinforced steel in steel pipe, steel pipe, be outer screed outside steel pipe, interior screed is filled between steel pipe and reinforced steel, reinforced steel is higher by the part of steel pipe and is connected with the horizontal reinforcement cage of Guan Liang.Supporting construction of the present utility model pours steel fiber reinforced concrete in steel duct insertion H profile steel, in steel duct, the intensity of steel-pipe pile can be significantly increased, the bonding between steel-pipe pile and surrounding soil can be strengthened by being mixed into steel fibre, and the performances such as the bending resistance of concrete, tension can be greatly improved, simultaneously, H profile steel top is cast in Guan Liang together with steel pipe top, and then improves anti-slide performance.
Description
Technical field
The utility model is related to a kind of miniature steel pipe pile supporting construction of built-in profile steel, belongs to technical field of civil engineering.
Background technology
Miniature steel pipe pile pile arrangement flexibly, suitable for a variety of soil layers, obtained in recent years in landslide control engineering extensively
Using, and achieve good consolidation effect.Its construction technology process approximately as：First in the region root for the processing that needs reinforcement
Drilled according to projected depth, then the steel pipe of insertion minor diameter, to sliding surface certain depth below, is finally irrigated in drilling
Concrete formation mini pile, to play AsA -GSH cycle.Compared with traditional friction pile, miniature steel pipe pile occupied ground is small, especially fit
For mountain area place, and speed of application is fast, is suitable for reinforcement for rushing danger engineering.
But it is due to that miniature steel pipe pile stake footpath is smaller, single pile anti-slide performance seems not enough sometimes, in Practical Project once
Occurred being bent over or cutting because steel-pipe pile anti-slide performance is not enough, and the situation that slope sliding is further increased.In addition,
Stress harmony between each stake is not enough so that with piece place some failures and other stakes can also continue to play a role, this
It is also unfavorable for overall consolidation effect.
The content of the invention
The purpose of this utility model is the miniature steel pipe pile supporting construction there is provided a kind of built-in profile steel.Overcome existing
The single pile anti-slide performance that miniature steel pipe pile is present is not enough and the not good defect of stress harmony between stake and stake.
The technical solution of the utility model：A kind of miniature steel pipe pile supporting construction of built-in profile steel, includes multiple embedments
The Guan Liang through resting on the ground is attached between at the top of the miniature steel pipe pile of underground, adjacent 2 miniature steel pipe piles；It is described miniature
Steel-pipe pile, which includes, has been put into reinforced steel in steel pipe, steel pipe, be outer screed outside steel pipe, filled out between steel pipe and reinforced steel
Filled with interior screed, reinforced steel is higher by the part of steel pipe and is connected with the horizontal reinforcement cage of Guan Liang.
The miniature steel pipe pile supporting construction of foregoing built-in profile steel, the interior screed is steel fiber reinforced concrete layer.
The miniature steel pipe pile supporting construction of foregoing built-in profile steel, the reinforced steel is H profile steel.
The beneficial effects of the utility model：Compared with prior art, supporting construction of the present utility model is inserted in steel duct
Enter H profile steel, pour steel fiber reinforced concrete in steel duct, the intensity of steel-pipe pile can be significantly increased, being mixed into steel fibre can increase
Bonding between steel-pipe pile and surrounding soil, and the performances such as the bending resistance of concrete, tension can be greatly improved by force, meanwhile, H profile steel
Top is cast in Guan Liang together with steel pipe top, and then improves anti-slide performance.
Brief description of the drawings
Accompanying drawing 1 is profile of the present utility model；
Accompanying drawing 2 is miniature steel pipe pile single pile top view；
Reference：Slip casting on the outside of Grouting Pipe on the inside of screed in 1- steel pipes, 2- reinforced steels, 3-, 4- drillings, 5-, 6-
Pipe, 7- horizontal reinforcement cages, 8- Guan Liangs, 9- miniature steel pipe piles, the outer screeds of 10-.
Embodiment
The utility model is further described with reference to the accompanying drawings and examples, but is not intended as to the utility model
The foundation of limitation.
Embodiment of the present utility model：A kind of miniature steel pipe pile supporting construction of built-in profile steel, as shown in accompanying drawing 1-2, bag
The Guan Liang 8 through resting on the ground between multiple buried miniature steel pipe piles 9, the adjacent top of 2 miniature steel pipe piles 9 has been included to enter
Row connection；The miniature steel pipe pile 9, which includes, has been put into reinforced steel 2 in steel pipe 1, steel pipe 1, the outside of steel pipe 1 is outer screed
10, interior screed 3 is filled between steel pipe 1 and reinforced steel 2, reinforced steel 2 is higher by part and the level of Guan Liang 8 of steel pipe 1
Steel reinforcement cage 7 is connected.This structure in steel pipe 1 due to being put into reinforced steel 2, and by interior screed 3 by reinforced steel 2 and steel pipe
1 pours together, can significantly increase the intensity of steel-pipe pile, and reinforced steel 2 and the top of steel pipe 1 are cast in Guan Liang 8, can shown
The globality of enhancing structure is write, and balances the force-bearing situation of each stake, integer support effect is improved.
Interior screed 3 is steel fiber reinforced concrete layer, and steel fiber reinforced concrete can strengthen between steel-pipe pile and stake surrounding soil
Bonding, it is possible to increase tension, bending resistance and the shearing strength of concrete, the especially tough performance of resistance to compression are increased substantially, Jin Erti
High anti-slide performance.
Reinforced steel 2 is H profile steel, and H profile steel is that a kind of area of section distribution more optimization, the ratio of strength to weight are more rational economical
Section high efficiency section bar.Because each position of H profile steel is with orthogonal arrangement, therefore H profile steel all has bending resistance in all directions
Ability is strong, simple, cost-effective and lightweight construction of constructing the advantages of.
The construction method of the supporting construction includes following steps：
The operation of drilling 4 is carried out first, steel pipe 1 is put into drilling 4, its top is higher by earth's surface certain altitude, then will
In the insertion steel pipe 1 of reinforced steel 2, its bottom is flushed with the bottom of steel pipe 1, and top is then higher by the certain altitude of steel pipe 1；Then, adopt
The mode starched with side tube drawing marginal not, by inner side Grouting Pipe 5 and outside Grouting Pipe 6 toward in steel pipe 1 and steel pipe 1 and 4 hole walls of drilling
Between space in perfusion flowing concrete respectively to the nozzle position of steel pipe 1 and ground surface, to form interior screed 3 and outer sand
Pulp layer 10；Treat after being finished with row's construction of miniature steel pipe pile 9, place horizontal reinforcement cage 7, casting concrete formation Guan Liang 8 will be each
Steel pipe 1 is higher by the part of earth's surface and reinforced steel 2 is higher by the part of the mouth of pipe of steel pipe 1 and is cast in Guan Liang 8, with enhancing structure
It can be also attached between globality, adjacent row steel-pipe pile by Guan Liang.
