Description
Technical field
The present invention relates to Geotechnical Engineering, specially heavy-gauge steel and the hollow friction pile of Combined concrete.
Background technology
Rock And Soil can produce slip deformation in additional load, deadweight, water, earthquake etc. in Geotechnical Engineering under other are acted on, and be
Some antiskid structures can be used by eliminating these deformations, wherein a kind of conventional antiskid structure is exactly friction pile, friction pile can profit
Part in stable Rock And Soil is anchored at as its fixing end by the use of it, ensures it under load action not using its strength of materials
Destroy, certain rigidity is obtained using its heavy in section size, so as to ensure that it does not produce big deformation under load action, from
And ensure the stability of slip mass.
Generally all in more than 2m, material is substantially all using armored concrete the sectional dimension of the friction pile used at present,
Section uses rectangle or square solid section form, and stake holes typically uses manually digging hole, to ensure peace of the stake in pore forming process
Quan Xing, the supporting construction of stake holes need to be made stage by stage in pore forming process to ensure the safety of pore-forming personnel and equipment.
Reinforced concrete anti-slide pile is because sectional dimension is larger, and landslide is typically in the open country of remote districts mostly in addition
Outside, it is relatively difficult by the way of mechanical hole building, so most of all use manual pore-forming's mode.Existing armored concrete is real
The deficiency of heart friction pile has at 5 points：First, manual pore-forming's process middle hole wall is possible to produce landslide under various loads and effect,
Therefore the supporting in pore-forming is just needed, can so influences construction speed；Second, stake must just can be with when pore-forming is to stake bottom absolute altitude
Placing concrete, also to influence construction speed；3rd, solid reinforced concrete anti-slide pile divides from the general principle of the mechanics of materials
Analyse, the material in a certain scope of its immediate vicinity can not play a role, waste of materials；4th, if to do piled anchor composite junction
If structure, anchor head must be on the outside of stake；5th, precast construction can not be used, it is impossible to realize that construction industry metaplasia is produced.
The content of the invention
For above-mentioned technical problem, the present invention provides a kind of prefabricated friction pile, accelerating construction progress.
Specifically technical scheme is：
Heavy-gauge steel and the hollow friction pile of Combined concrete, including multiple pile sections, described pile section are formed square by steel
Framework, the interior outside of described quadra are surrounded by concrete；Described inner side concrete upper and lower side exposes steel, described pile section
It is stacked on top of one another, tie point is formed between the steel of neighbouring pile section, there is second coagulation soil LIFT at tie point.
Described steel are steel plate or shaped steel.
The 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, stake holes depth are a pile section；
(3) the pile sinking section in stake holes, then open next section stake holes；
(4) after the completion of excavating, the second section pile section is just put, the second section pile section is connected to form tie point 4 with first segment pile section, even
Junction concrete is poured after connecing and forms second coagulation soil LIFT 3；
(5) continue to excavate next stake holes, so repeatedly until whole pile installs.
Heavy-gauge steel provided by the invention and the hollow friction pile of Combined concrete, are mixed using built-in steel plate or shaped steel, outsourcing
The combining structure form of soil is coagulated, can be prefabricated according to design drawing progress at the scene, it can be carried out stage by stage in pore forming process
Installation, mounted pile section can both work as safeguard structure and use, and be a part for Anti-slide engineering stake again, kill two birds with one stone；And stake
The installation of section and manual pore-forming are carried out simultaneously, save the duration；Hollow parts can not only turn into the operation of pore-forming worker
Space, and also save material；Compared to reinforced concrete section, there is more steel with Combined concrete section under equal conditions
Big bending rigidity and better structure ductility, bigger antiskid bearing capacity can be obtained in the case of less wall thickness.Large scale
Steel and the hollow friction pile of Combined concrete, have security is good, save material, good mechanical property, short construction period, can be real
Several big advantages such as existing industrialized production.
Brief description of the drawings
Fig. 1 is the cross-sectional structure schematic diagram of the present invention；
Fig. 2 is the construction schematic diagram of the present invention.
Embodiment
The embodiment of the present invention is described with reference to the drawings.
Heavy-gauge steel and the hollow friction pile of Combined concrete, including multiple pile sections, described pile section are formed square by steel 1
Framework, the interior outside of described quadra are surrounded by concrete 2；Described inner side concrete upper and lower side exposes steel 1, described stake
Stacked on top of one another, formation tie point 4 between the steel of neighbouring pile section is saved, has second coagulation soil LIFT 3 at tie point 4.
Described steel are steel plate or shaped steel.
The combining structure that pile section is made up of built-in steel plate or shaped steel and two kinds of materials of the concrete of outsourcing, its steel 1 are thick
Degree is typically about 2~5mm, and strength grade of concrete typically uses more than C25, and the two forms combining structure, and concrete parts can
To limit the unstability outside the plane under horizontal shear acts on of steel 1, to ensure that it is good that the bearing capacity of steel 1 planar can obtain
Good performance, while steel non-corrosive can also be protected, steel 1 are in close contact with concrete 2 can limit concrete cracking, carry
The durability of high concrete.Heavy-gauge steel and the section of the hollow friction pile of Combined concrete are as shown in Figure 1.
Heavy-gauge steel and the work progress of the hollow friction pile of Combined concrete, as shown in Fig. 2 first in precasting yard according to structure
The prefabricated peg board of design drawing and pile section, stake holes is then manually started into, when stake holes depth is a pile section length can pile sinking section,
At this moment pile section is both the safety support fender pile of next section of stake holes pore-forming, is a part for antiskid structure again.Etc. next section pore digging
After the completion of, the second section pile section is just put, the second section pile section is connected to form tie point 4 with first segment pile section, and junction is poured after connection
Concrete forms second coagulation soil LIFT 3, then proceedes to excavate stake holes, so repeatedly until whole pile installs.
