Specific embodiment
Here is that the present invention will be further described in conjunction with the accompanying drawings and embodiments.
Embodiment one
- Fig. 3 referring to Fig.1, architectural engineering chock stake, including pile body 1, wedge block 2 and steel pipe 3.
Wherein, it is equipped with through-hole 4 at the middle part of pile body 1, is connected to equipped with multiple with through-hole 4 on pile body 1 along 1 length direction of pile body
Rectangle hole 5, be located on pile body 1 rectangle hole 5 on same cross section at least there are two, be evenly arranged, lead to around pile body central point
The diameter in hole 4 is slightly larger than the diameter of steel pipe 3, after such steel pipe 3 protrudes into through-hole 4, the wedge block 2 in rectangle hole 5 can be squeezed
It goes out, to stretch out the outer surface of pile body 1, forms chock with the mating surface 6 of 5 upper end of rectangle hole.Steel pipe 3 is movably arranged on pile body
In 1 through-hole 4, and the end of steel pipe 3 is equipped with the tip 7 for squeezing wedge block, the taper and wedge block of the outer surface at tip 7
2 inclined-plane 25 is adapted.
Wedge block 2 is movably arranged in rectangle hole 5 and one end passes through external force stretching rectangle hole 5, the size and square of wedge block 2
5 size of shape hole is adapted, and the upper end in rectangle hole 5 is equipped with mating surface 6 compatible with the angle on inclined-plane 25 of wedge block 2；Wherein,
Wedge block 2 includes the upper surface 21 and lower end surface 22 being parallel to each other, and 21 size of upper surface is less than 22 size of lower end surface；Vertically
Connect the left side 23 of upper surface 21 and 22 side of lower end surface；With the vertically disposed right side 24 in 22 other side of lower end surface, right end
The height in face 24 is less than the height of left side 23；For connecting the inclined-plane 25 of right side 24 and upper surface 21, the inclination of inclined-plane 25 is set
It sets.This 2 structure of wedge block forms the structure that longitudinal cross-section is essentially right-angled trapezium.The size of lower end surface 22 is greater than under rectangle hole 5
End size squeezes wedge block 2 in this way after steel pipe 3 protrudes into through-hole, it is made to stretch out rectangle hole 5.In the effect of steel pipe 3
Under, the left side 23 of wedge block 2 is connected to upper and lower end face stretching rectangle hole 5 and connect with the external soil body.
Embodiment two
Pile body 1 is hollow preformed pile, and the section of pile body 1 is round, rectangle or polygon.Wedge block 2 is concrete, steel
Material, plastics etc. are made, and are applicable to special-shaped hollow preformed pile of various shapes.
When specifically used, in the side of pile body 1, the rectangle hole 5 of several about 10cm x25cm, rectangle hole are opened along stake length direction
5 upper ends are made into inclined mating surface 6, and rectangle hole 5 is circular layout about 2 ~ 3 along the cross section of pile body 1, the built-in size in rectangle hole 5
It is slightly less than the wedge block 2 at hole.When construction, first the pile body 1 of built-in wedge block 2 is driven underground, then again in the hollow of pile body
In through-hole 4, the end that indentation diameter is slightly less than through-hole 4 is the steel pipe 3 at pyramid type tip 7, is squeezed by steel pipe 3, forces and be hidden in
Wedge block 2 in the rectangle hole 5 of pile body 1 is extruded pile body 1, to form the chock stake of band " ear ".It then will be at through-hole 4
Steel pipe 3 is extracted, and sand or concrete 26 etc. are inserted in through-hole 4, prevents wedge block 2 from being squeezed into the rectangle hole 5 of pile body 1 by soil again
It is interior.When the normal work of pile body 1 with wedge block 2, bears vertical load pressure and gradually settle, the cooperation of 5 upper end of rectangle hole
Face 6 can force wedge block 2 to be displaced outwardly along inclined-plane 25, the pile peripheral earth 27 around pile body 1 be squeezed, to realize the work of chock
With, the bearing capacity of stake is greatly improved, it is reliable and stable, while reducing project cost.
The mechanism of action of bearing power increase: chock is a kind of small tool for having certain inclination angle, be filled in two implements it
Between, when two sides, the changing of the relative positions occur in implements, downward strength can be switched to horizontal expansion strength by chock, to strengthen two sides device
Connection between object.The wedge block 2 of the utility model chock stake side is just as the chock between pile body and surrounding soil, rectangle
The tilt angle on 2 inclined-plane 25 of mating surface 6 and wedge block of 5 upper end of hole, realizes the effect of chock, holding for stake is greatly improved
Carry power.
By experimental study, the utility model chock pile bearing capacity is the 2 times or more of traditional common prefabricated pile.Comprehensively consider, it should
Current 50% or more prefabricated pile economic benefit can be improved in novel chock stake.
The quantity of the chock that the utility model chock stake side is circular layout along stake diameter, size, the size at hole and long along stake
Spacing etc. can adjust accordingly.
The utility model is not limited to above-mentioned embodiment, within the knowledge of those skilled in the art,
The present invention can also be realized without departing from the purpose of the present invention. Make a variety of changes, and the content after variation still falls within the utility model
Protection scope.
