Abstract
The invention relates to geotechnical engineering, in particular to a large-dimension steel and concrete combined hollow anti-slide pile and a construction method thereof. The large-dimension steel and concrete combined hollow anti-slide pile comprises a plurality of pile sections which form a square framework by virtue of steel products, wherein concrete covers the inner side and the outer side of the square framework; the steel products are exposed from the upper end and the lower end of the concrete at the inner side; the pile sections are stacked up and down; a connecting point is formed between the steel products of upper and lower adjacent pile sections; and the connecting point is provided with a secondary concrete layer. The large-dimension steel and concrete combined hollow anti-slide pile provided by the invention is mounted in stages in a hole forming process, the mounted pile sections can be used as a protective structure, and are also used as one part of an anti-slide engineering pile, so that the construction speed is shortened, and the materials are saved; and the large-dimension steel and concrete combined hollow anti-slide pile has greater bending rigidity and better structure ductility, so that greater anti-slide bearing capacity can be obtained when the wall thickness is relatively small.
Description
Technical field
The present invention relates to Geotechnical Engineering, specially heavy-gauge steel and the hollow friction pile of Combined concrete.
Background technology
In Geotechnical Engineering, Rock And Soil can produce slip deformation under other effects such as additional load, deadweight, water, earthquake, for eliminating
These deformation can use some antiskid structures, and wherein conventional a kind of antiskid structure is exactly friction pile, and friction pile can utilize its anchor
Gu the part in stable Rock And Soil is as its fixing end, utilize its strength of materials to ensure that it does not destroys under load action, profit
Obtain certain rigidity by its heavy in section size, thus ensure that it does not produce big deformation under load action, thus ensure sliding
The stability of slope body.
The sectional dimension of the friction pile used at present is generally all at more than 2m, and material is substantially all employing armored concrete, and cross section is adopted
By rectangle or square solid section form, stake holes typically uses manually digging hole, for ensureing stake safety in pore forming process, needs
The supporting construction of stake holes is made stage by stage to ensure the safety of pore-forming personnel and equipment in pore forming process.
Reinforced concrete anti-slide pile is relatively big due to sectional dimension, comes down in addition and is mostly typically in the field of remote districts, uses
The mode of mechanical hole building is relatively difficult, so great majority all use manual pore-forming's mode.The solid friction pile of existing armored concrete
Deficiency have 5 points: first, during manual pore-forming, hole wall likely produces landslide under various loads and effect, therefore just needs
Want limit pore-forming limit supporting, so can affect construction speed；Second, stake just must can water coagulation when pore-forming to absolute altitude at the bottom of stake
Soil, construction speed to be affected；3rd, solid reinforced concrete anti-slide pile is analyzed from the ultimate principle of the mechanics of materials, wherein
Near the heart, the material in a certain scope can not play a role, and wastes material；4th, if piled anchor composite construction to be done,
Anchor head must be outside stake；5th, it is impossible to use precast construction, it is impossible to realize construction industry metaplasia and produce.
Summary of the invention
For above-mentioned technical problem, the present invention provides a kind of prefabricated friction pile, accelerating construction progress.
Concrete technical scheme is:
Heavy-gauge steel and the hollow friction pile of Combined concrete, including multiple pile sections, described pile section is formed quadra by steel,
In described quadra, outside is surrounded by concrete；Described inner side concrete upper and lower side exposes steel, described pile section levels
Folded, form junction point between the steel of neighbouring pile section, at junction point, have second coagulation soil LIFT.
Described steel are steel plate or shaped steel.
This heavy-gauge steel and the construction method of the hollow friction pile of Combined concrete, including procedure below:
(1) in the prefabricated pile section of precasting yard；
(2) digging in-situ stake holes, the stake holes degree of depth is a pile section；
(3) pile sinking joint in stake holes, then open next joint stake holes；
(4) after having excavated, just putting second section pile section, second section pile section is connected formation junction point 4 with first segment pile section, connects
Rear pouring junction concrete forms second coagulation soil LIFT 3；
(5) the next stake holes of excavation is continued, the most repeatedly until whole pile installs.
Heavy-gauge steel and the hollow friction pile of Combined concrete that the present invention provides, uses built-in steel plate or shaped steel, external wrapping concrete
Combinative structure form, can carry out prefabricated according to design drawing at the scene, and it can be installed in pore forming process stage by stage, peace
The pile section installed both can have been worked as safeguard structure and use, and is again a part for Anti-slide engineering stake, kills two birds with one stone；And the installation of pile section
Carry out with manual pore-forming simultaneously, save the duration；Hollow parts not only can become the working place of pore-forming workman, and
Also save material；Compared to reinforced concrete section, under equal conditions, steel and Combined concrete cross section have bigger bending resistance firm
Degree and better structure ductility, can obtain bigger antiskid bearing capacity in the case of less wall thickness.Heavy-gauge steel and coagulation local soil type
Close hollow friction pile, have safety good, save material, good mechanical property, short construction period, can realize industry metaplasia
Several big advantages such as product.
Accompanying drawing explanation
Fig. 1 is the cross-sectional structure schematic diagram of the present invention；
Fig. 2 is the construction schematic diagram of the present invention.
Detailed description of the invention
The detailed description of the invention of the accompanying drawings present invention.
Heavy-gauge steel and the hollow friction pile of Combined concrete, including multiple pile sections, described pile section is formed quadra by steel 1,
In described quadra, outside is surrounded by concrete 2；Described inner side concrete upper and lower side exposes steel 1, and described pile section is upper and lower
Stacking, forms junction point 4, has second coagulation soil LIFT 3 at junction point 4 between the steel of neighbouring pile section.
Described steel are steel plate or shaped steel.
The combinative structure that pile section is made up of the concrete bi-material of built-in steel plate or shaped steel and outsourcing, its steel 1 thickness is general about
Being 2～5mm, strength grade of concrete typically uses more than C25, and the two forms combinative structure, and concrete parts can limit steel
The outer unstability of the material 1 plane under horizontal shear effect, to ensure that steel 1 bearing capacity planar can obtain good performance,
Can also protect steel non-corrosive, steel 1 are in close contact with concrete 2 can limit concrete cracking, improves concrete simultaneously
Durability.The cross section of heavy-gauge steel and the hollow friction pile of Combined concrete is as shown in Figure 1.
Heavy-gauge steel and the work progress of the hollow friction pile of Combined concrete, as in figure 2 it is shown, first at precasting yard according to structural design drawing
The prefabricated peg board of paper and pile section, be then manually started into stake holes, just can save by pile sinking, at this moment stake when the stake holes degree of depth is a pile section length
Joint is the safety support fender pile of next section of stake holes pore-forming, is again a part for antiskid structure.After completing Deng next joint pore digging,
Just putting second section pile section, second section pile section is connected formation junction point 4 with first segment pile section, waters junction concrete and formed after connection
Second coagulation soil LIFT 3, then proceedes to excavate stake holes, the most repeatedly until whole pile installs.
