Description
Technical field
The invention belongs to soil body stability studying technological domains, and in particular to a kind of hollow anti-liquefaction stake of antiskid.
Background technique
Ordinary reinforced concrete prefabricated pile is divided into two class of solid pile body and hollow pile body, although wherein solid pile intensity is high,
Hardness is big, but can usually have the problems such as cost height not convenient for transportation and constructing operation；Though and hollow pile is light easily applies
Work but there can be intensity unstability easy to damage not up to standard.Being often used in construction at present only has the hollow pre- of a circular hole road
Reinforced concrete pile processed, but since engineering is actually limited, when encountering the excessive situation of requirement pile body cross-sectional area, only have
The problems such as long period project amount that the pile body of one stake holes will appear that difficulty of construction is big in the construction process is more, sometimes can also be because
For due to the excessive problem no longer up to standard so as to cause pile body integral strength of single hole area, and in the soil body caused by soil liquefaction
Sediment failure phenomenon is also the problem of should improving emphatically in engineering.
Summary of the invention
Of the existing technology in order to solve the problems, such as, the present invention provides a kind of anti-liquefaction stake of hollow antiskid, and technical solution is such as
Under:
A kind of anti-liquefaction stake of hollow antiskid, including pile body, cuboid protrusion, catch basin, suction eye, water-guiding hole, along described
Pile body periphery is evenly equipped with several cuboid protrusions, offers catch basin respectively on the outside of several cuboid protrusions, several catch basins
Outside is respectively arranged with filter screen, and pile body center offers suction eye, several catch basins pass through water-guiding hole and suction eye respectively
Connection, pile body are internally provided with the duct of several perforations, and pile body bottom is fixed with pile crown, the cuboid protrusion, catch basin, pumping
Water hole is arranged in parallel with the axis of pile body.
There are three the cuboid protrusion is specifically arranged, arrangement in equilateral triangle between three cuboid protrusions.
There are three the duct is specifically arranged, arrangement in equilateral triangle between three ducts, and three ducts and three
It is staggered between cuboid protrusion.
Suction pump is provided in the suction eye.
The pile body is the reinforced concrete pile body prepared in prefabrication practice.
The pile crown is solid pile crown.
The filter screen is double-layer stainless steel filter screen.
The length of the pile body is two times of soil property slider bed.
Several longitudinal reinforcements are axially evenly arranged in the pile body along pile body, the end insertion pile foundation of longitudinal reinforcement is held
In platform.
The distance between any two duct is all larger than the radius in duct itself.
Compared with prior art, the beneficial effects of the present invention are:
The present invention has the characteristics that the anti-liquefaction of draining, and catch basin, water storage is arranged on the outside of the cuboid protrusion of pile body periphery
Covered using double-layer stainless steel filter screen outside slot, with prevent due to partial size block big in the soil body passes through when cause filter screen to block up
Plug is unified after the water in catch basin being directed in drinking-water pipe by the way that water-guiding hole is arranged in pile body to be extracted out by suction pump.
Meanwhile perforation duct is set to save material, reduce weight in pile body, it is high inconvenient to eliminate pile body cost
The problem of transport, solves the problems, such as easy sliding pile in the antiskid cuboid protrusion of pile body periphery setting, to guarantee reinforcing side slope,
The effects of anti-skidding.
The advantages that present invention has structure simple, convenient for construction, saves material, and transport is convenient, overcomes common pile foundation and exists
Many disadvantages during prefabricated construction.

Specific embodiment
It is to be appreciated that the directional instruction (such as up, down, left, right, before and after ...) of institute is only used in the embodiment of the present invention
In explaining in relative positional relationship, the motion conditions etc. under a certain particular pose (as shown in the picture) between each component, if should
When particular pose changes, then directionality instruction also correspondingly changes correspondingly.
As shown in Figures 1 to 4, the present invention provides a kind of hollow anti-liquefaction stakes of antiskid, including pile body 1, cuboid protrusion
2, catch basin 3, suction eye 4, water-guiding hole 5 are evenly equipped with several cuboid protrusions 2 along 1 periphery of pile body and are mentioned with playing AsA -GSH cycle
The anti-slide performance of high soil-slope and shearing resistance are horizontal, and several 2 outsides of cuboid protrusions offer catch basin 3 respectively, several
Filter screen 6 is respectively arranged on the outside of catch basin 3,1 center of pile body offers suction eye 4, several catch basins 3 pass through water guide respectively
Hole 5 is connected to suction eye 4, it is preferred that water-guiding hole 5 is disposed proximate to the position of 1 lower end of pile body, and water is come together in middle part suction eye
It is unified after in 4 to be extracted out by suction pump 9, play the role of resisting the soil body liquefied, pile body 1 is internally provided with the hole of several perforations
Road 7, for reducing 1 quality heavy of pile body, 1 bottom of pile body is fixed with pile crown 8, and cuboid protrusion 2, catch basin 3, suction eye 4 are equal
It is arranged in parallel with the axis of pile body 1.
There are three cuboid protrusion 2 is specifically arranged, arrangement in equilateral triangle between three cuboid protrusions 2.
Duct 7 is specifically there are three settings, arrangement in equilateral triangle between three ducts 7, and three ducts 7 and three long
It is staggered between cube protrusion 2, water-guiding hole 5 is on the one hand made to be staggered with duct 7, on the other hand improve the whole stabilization of pile body 1
Property.
Suction pump 9 is provided in suction eye 4.
Pile body 1 is the reinforced concrete pile body 1 prepared in prefabrication practice.
Pile crown 8 is solid pile crown 8, the intensity of pile crown 8 when guaranteeing to squeeze into pile body 1, while being prevented under drilled pile during stake
Due to the destruction unstability of pile crown 8 or even pile body 1 caused by soil body resistance.
Filter screen 6 is double-layer stainless steel filter screen.
The length of pile body 1 is two times of soil property slider bed.
Several longitudinal reinforcements are axially evenly arranged with along pile body 1 in pile body 1, pile foundation cushion cap is inserted into the end of longitudinal reinforcement
In.
The distance between any two duct 7 is all larger than the radius in duct 7 itself.
In use, hollow anchorage depth of sliding resistant piles uses 2~5 times of 1 diameter of pile body when soil layer is slided along bedrock surface,
Meanwhile the stake spacing of the anti-liquefaction stake of the hollow antiskid of the present invention generally takes 3~5 times of 1 diameter of pile body, to guarantee that sliding soil mass does not exist
It is skidded off between stake.
In addition, the present invention need to use the construction method (drilling construction method) of drilled pile when constructing, to prevent the destruction of pile body 1, and
The disturbance of surrounding soil reduces intensity.
The above embodiments are merely illustrative of the technical scheme of the present invention and are not intended to be limiting thereof, although referring to above-described embodiment pair
The present invention is described in detail, and the those of ordinary skill in field is it is understood that still can be to specific embodiment party of the invention
