Description
Technical field
The utility model relates to construction, in particular to a kind of uplift pile with hangnail.
Background technique
Uplift pile refer to when architectural engineering underground structure if there is be lower than Soil Surrounding water level part when, in order to offset
The stake that water beats the buoyancy that structure generates in soil, uplift pile are widely used in big basement anti-floating, high-rise structures
Resistance to plucking, tidal quay platform resistance to plucking, the rock anchorage base of suspension bridge and cable-stayed bridge, the pile foundation of Large Ship Dock bottom plate and dead load examination
Rock anchorage base etc. in stake.
The bearing capacity of stake depends on the frictional force of stake side wall, in the case that soil layer soil structure is poor, pile body and ground
Friction is small for lower soil layer, so that pile body is easily pulled out, influences building safety.
Utility model content
The purpose of the utility model is to provide a kind of uplift piles with hangnail, have and increase pile body and sub-surface frictional force
The advantages of.
The above-mentioned technical purpose of the utility model has the technical scheme that
A kind of uplift pile with hangnail, including pile body and pile top, the pile body middle part are provided along its length holding tank,
The side wall of the pile body offers several embedded holes being connected to holding tank, and axis of the embedded hole about pile body along its axis direction
Line is symmetrical arranged, and the embedded hole is rotatably connected to hangnail close to the side of pile top, and the hangnail is towards the side of holding tank
It is fixedly connected with wedge block, and the inclined-plane of wedge block is towards pile top；
Sliding is connected with pull rod in the holding tank, and the outside of the pull rod is fixedly connected with and wedge shape along its length
The inconsistent convex block in the inclined-plane of block.
By using above-mentioned technical proposal, then uplift pile passes through hammering before use, first pull rod is inserted into holding tank
Or the mode of static pressure squeezes into uplift pile in soil layer, then lifts pull rod upwards by equipment so that the convex block on pull rod with
The inclined-plane of wedge block contradicts, and as the distance that pull rod pulls is bigger, the distracted distance of wedge block is bigger, so that hangnail is to remote
Side from pile body is opened, so that the frictional force of pile body and soil layer is improved, so that the bearing capacity of uplift pile obtains further
It improves, generates powerful withdrawal resistance.
Further, the hangnail is tiltedly installed with guide surface far from the side of wedge block, and guide surface is towards pile top.
By using above-mentioned technical proposal, opposite guide surface can not only play the role of guiding guidance with for plane,
Soil is also reduced to the resistance of pile body, so that pile body insertion is more convenient.After hangnail is opened, part soil, which is also clamped in, is led
To between face and pile body lateral wall, so that soil is bonded tighter with pile body, pile body is less drawn out easily.
Further, sleeve is rotatably connected on the side wall of several embedded holes, sliding is connected in the sleeve
Telescopic rod, the one end of the telescopic rod far from sleeve and wedge block are rotatablely connected, opening of the sleeve far from embedded hole to
Interior extension restraining position ring block, the telescopic rod are outward extended with far from one end of hangnail and keep out ring with what stop collar contradicted.
By using above-mentioned technical proposal, one is kept equipped with the angle that sleeve and telescopic rod open all hangnails
It causes, to make hangnail uniform force, also makes hangnail be not easy to continue to overturn to pile top direction, improve the intensity of hangnail.
Further, the fill orifice through pull rod both ends is provided along its length in the middle part of the pull rod.
By using above-mentioned technical proposal, concrete is poured into from fill orifice, so that being mixed during pull rod is extracted upwards
Solidifying soil enters in holding tank from the bottom end of pull rod, to increase the frictional force of concrete and pile body, to increase concrete
Bond strength between pile body improves the tensile capacity of tension stake.
Further, array has several grooves to the cell wall of the holding tank along its length.
By using above-mentioned technical proposal, groove further increases the conjugation between concrete and pile body, so that mixed
Solidifying soil is not easily to fall off, improves the tensile capacity of concrete.
Further, the pile body is fixedly connected with pile cover far from one end of pile top.
By using above-mentioned technical proposal, when pull rod during pulling out outward, pressure is applied to pile cover, passes through pile cover pressure
Pile body processed, so that pile body is not easy the movement with pull rod and generates movement, so that the soil reduced around pile body loosens.Stake simultaneously
Cap also increases the contact area of pile body and fullering tool, so that fullering tool can be hammered onto pile body every time, to accelerate anti-
The construction of pile pulling.
Further, the middle part of the pile cover is equipped with the flaring of inverted cone-shaped, and the one end being flared is connected to holding tank.
By using above-mentioned technical proposal, it is equivalent to equipped with flaring and increases the notch of holding tank, thus more convenient drawing
Bar is installed in holding tank, is improved work efficiency.
Further, the pile body is equipped with annular protruding rib close to one end external circumferential of pile top, and annular protruding rib is along stake
Body axis direction is equipped with several.
By using above-mentioned technical proposal, annular protruding rib further increases the frictional force and resistance to plucking energy of pile body and soil layer
Power, to improve the anchoring property of pile body and soil layer.
In conclusion the utility model has the following beneficial effects:
1. using pull rod, convex block, wedge block, hangnail, it can play and open hangnail to the direction far from pile body, increase
The frictional force of pile body and soil layer, to increase the effect of the tensile capacity of uplift pile；
2. using sleeve and telescopic rod, it can play and keep the angle of all hangnails openings consistent, so that hangnail stress
Uniform effect；
3. using fill orifice, the tensile capacity of uplift pile is improved by increasing the frictional force between concrete and pile body
Effect；
4. using flaring, it can play and pull rod is facilitated to be installed to the effect in holding tank.
