Description
Technical field
The utility model is related to a kind of barb-shaped prefabricated piles suitable for soft clay area.
Background technology
Stake is the common method of basement process.Normal sequence of construction is first to drive piles, then do cushion cap, and be connected sheet
Cushion cap is commonly referred to as sole plate, column of then constructing, wall, the superstructures such as beam, until superstructure is completed, into normally making
With.Stake is embedded in underground, can only passively bear upper load, compared be more difficult to do over again for superstructure, reinforcement and strengthening, for
For ground, in case of differential settlement, the measure remedied further includes the weakening to local ground, such as small settling
Side is cut the earth, to promote its sedimentation.On the whole, the measure remedied is limited in current technology, after basement process failure, effect
Fruit is bad, cost is higher, geotechnical engineer is forced relatively to be guarded when carrying out basement process in terms of certain at this, stringent limitation sedimentation
Amount causes to determine that safety coefficient is excessively high during the bearing capacity of the bearing capacity of soil and stake, increases cost, waste more society's money
Source.
By changing stake vertical section, can be good at providing additional frictional resistance, while also can effectively lower material
The dosage of material, economizes on resources, this is beneficial to change the innovation of the vertical section of pile body with popularizing.
Invention content
The technical problem to be solved by the present invention is to provide a kind of barb-shaped prefabricated piles suitable for soft clay area.
In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model is a kind of falling suitable for soft clay area
Hook-type prefabricated pile, including pile body and barb-shaped convex wedge；Barb-shaped convex wedge is attached to pile body surface；
Barb-shaped convex wedge includes curve slope, groove and top surface, and curve slope is downward, and upward, top surface is plane to groove.
Preferably, a plurality of barb-shaped convex wedges are distributed in pile body surface.
Further to be preferably, a plurality of barb-shaped convex wedges are evenly distributed with along pile body peripheral surface.
Further preferably a plurality of barb-shaped convex wedges are evenly distributed with along pile body axial surface, and positioned at the barb on upper strata
The convex wedge of shape is staggeredly arranged with the barb-shaped convex wedge positioned at lower floor.
Preferably, barb-shaped convex wedge is internally provided with bent-up bar, the bent-up bar and the bar connecting inside pile body,
And barb-shaped convex wedge is formed with pile body using concrete formed by integrally casting simultaneously.
The beneficial effects of the utility model are：
Pile body surface sets multiple barb-shaped convex wedges, offer frictional resistance that can be additional, the ditch on barb-shaped convex wedge top
Slot design can be firmly embedded in the soil body, can effectively reduce pile body lateral displacement.

Specific embodiment
Fig. 1 is a kind of barb-shaped prefabricated pile suitable for soft clay area, is made of pile body and barb-shaped convex wedge.There are multiple barbs
The convex wedge of shape is attached to pile body surface, and barb-shaped convex wedge is formed with pile body using concrete formed by integrally casting simultaneously.
Barb-shaped convex wedge is distributed on the surface of pile body 1 by following rule：
(1) 3 barb-shaped convex wedge forms one layer of barb-shaped convex wedge, and be evenly distributed with along pile body peripheral surface.
(2) along pile body axial surface by the barb-shaped convex wedge of spacing arranging multiplayer of setting, and the barb-shaped convex wedge 2 in upper strata is under
The barb-shaped convex wedge 3 of layer is staggeredly arranged up and down along pile body axial surface.
In fig. 2, the outer surface of the barb-shaped convex wedge 2 in upper strata is curve slope 203 directed downwardly, is had on barb-shaped convex wedge
One recessed groove 202, and top surface 201 is plane.
Equally, the outer surface of the barb-shaped convex wedge 3 of lower floor is curve slope 303 directed downwardly, has one on barb-shaped convex wedge
The recessed groove 302 of item, and top surface 301 is plane.
The distance of upper and lower two layers of barb-shaped convex spaced wedge setting.
In figure 3, it is just staggeredly arranged positioned at 3 barb-shaped convex wedges on upper strata and 3 barb-shaped convex wedges positioned at lower floor,
The angle that the upper and lower are staggered causes 3 barb-shaped convex wedges on upper strata and 3 barb-shaped convex wedge complementations of lower floor constitute it is whole
An a circumference.
To improve the intensity of barb-shaped convex wedge, used in the bent-up bar that is internally provided with of barb-shaped convex wedge, and when prefabricated
Concrete forms barb-shaped convex wedge with pile body formed by integrally casting.
The present embodiment sets multiple barb-shaped convex wedges on pile body surface, offer frictional resistance that can be additional, barb-shaped convex
The trench design on wedge top can be firmly embedded in the soil body 4, can effectively reduce pile body lateral displacement (Fig. 4).
Specifically, what design of the design of the curve slope of barb-shaped convex wedge compared to branch can be more easy to squeezes into soil
Body, and the design of upper groove so that a kind of inverted hook shape is integrally formed in barb-shaped convex wedge, greatly improves stake
Breakout capacity and frictional resistance.Stake is squeezed into after the soil body, and the part soil body has tamped the trench portions of barb-shaped convex wedge, barb-shaped convex
Wedge is preferably embedded within the soil body.When stake generates lateral displacement, the soil body in groove provides additional restraining force,
Reduce lateral displacement.
Above-described the utility model embodiment, does not form the restriction to scope of protection of the utility model.It is any
Modifications, equivalent substitutions and improvements made within spirit of the present utility model and principle etc., should be included in the utility model
