Abstract
The utility model rotation earth anchor is made up of spirally anchor pole, the big blade of spiral, continuous thread blade, using the combining form of king bolt blade and continuous thread, it is ensured that load-carrying properties of the screw anchor in the hard soil body;Put the first edge on a knife or a pair of scissors design for the end of burying of helical blade and continuous thread blade, screw anchor is had effect of preferably breaking ground in work progress, pass through the design of putting the first edge on a knife or a pair of scissors of blade so that screw anchor can be pierced smoothly in the hard soil body;Screw anchor bearing capacity can be improved by the combining form of continuous thread blade and the big blade of spiral, continuous thread blade draws hole effect when piercing, improve the perpendicularity for the process that pierces, ensure the performance of screw anchor load-carrying properties, not only hard soil is regional, soft soil area is also applied for simultaneously, requirement for bearing capacity is met.
Description
【Technical field】
The utility model belongs to Geotechnical Engineering pile foundation technical field, is related to a kind of screw anchor.
【Background technology】
In photovoltaic solar power generation infrastructure, solar panels and the firm of solar power generation support are associate power facilities
The guarantee of continuous firing.Screw anchor is a kind of novel pile basis, by the collective effect of pile body and helical blade, improves basis
Bearing capacity.Screw anchor basis has that form is simple, bearing capacity play it is fast, be easy to construction, it is cheap the features such as, it is suitable to use
Make the basis of photovoltaic solar generating board mount.
Current screw anchor is mainly applicable the softer area of the soil properties such as clay, and in loess, sand soil area, due to soil property bar
Part is to constructing and using the limitation of process, and the bearing capacity of screw anchor is played by a definite limitation.Helical blade can be greatly improved
The bearing capacity of anchor body, in the hard soil body, conventional helical earth anchor, which pierces difficulty because work progress occurs, causes perpendicularity not
Enough, the problems such as piercing deviation influences the performance of screw anchor bearing capacity.
【Utility model content】
The purpose of this utility model is to provide under the conditions of a kind of hard soil, can meet vertical compression and vertically pulling-resistant carrying
The screw anchor of power requirement.
To reach that above-mentioned purpose the utility model uses following scheme:
A kind of screw anchor, including the big blade of anchor pole, spiral and continuous thread blade;The big blade of spiral and continuous thread leaf
Piece is connected by welding with anchor pole;Anchor pole buries end for the solid conehead in stake end, and the big blade of spiral and continuous thread blade are made for rotation
Spiral steel disc, the big blade of spiral and continuous thread blade bury end provided with the blade blade tip that puts the first edge on a knife or a pair of scissors, and continuous thread blade is big in spiral
Buried end close to anchor pole below blade.
Further, the big blade of multiple spirals is set along anchor pole is spaced apart.
Further, continuous thread blade is equal pitch thread.
Further, anchor pole is solid construction.
Further, rock bolt shank, which is offered, pierces equipment connecting hole.
Screw anchor of the present utility model is made up of spirally anchor pole, the big blade of spiral, continuous thread blade, using big spiral shell
The combining form of vane piece and continuous thread, it is ensured that load-carrying properties of the screw anchor in the hard soil body;For helical blade and
The end of burying of continuous thread blade is put the first edge on a knife or a pair of scissors design, screw anchor is had effect of preferably breaking ground in work progress, is passed through leaf
The design of putting the first edge on a knife or a pair of scissors of piece so that screw anchor can be pierced smoothly in the hard soil body;Pass through continuous thread blade and the big blade of spiral
Combining form can improve screw anchor bearing capacity, continuous thread blade draws hole effect when piercing, and raising pierces process
Perpendicularity, it is ensured that the performance of screw anchor load-carrying properties, not only hard soil area, while being also applied for soft soil area, meets
Requirement for bearing capacity.
【Brief description of the drawings】
Fig. 1 is structural representation of the present utility model;
In figure:1 is anchor pole, and 2 be the big blade of spiral, 3 continuous thread blades, and 4 put the first edge on a knife or a pair of scissors blade blade tip, and 5 is pierce equipment company
Hole is connect, 6 be the solid conehead in stake end.
【Embodiment】
The utility model scheme is described in detail with reference to the accompanying drawings and examples:
As shown in figure 1, screw anchor includes anchor pole 1, the big blade 2 of spiral and continuous thread blade 3, anchor pole 1 is solid knot
Structure, the big blade 2 of spiral and continuous thread blade 3 are connected by welding with anchor pole 1;Anchor pole 1 buries end for the solid conehead 6 in stake end,
The shaft above ground portion of anchor pole 1, which leaves, pierces equipment connecting hole 5, and the stake of anchor pole 1 is long and stake footpath is calculated by Practical Project demand
Arrive;The big blade 2 of spiral and continuous thread blade 3 is revolve spiral steel disc processed, and blade tilt, rotation series and radius pass through actual work
Journey demand is calculated and obtained, and the big blade 2 of spiral and the blade place of burying of continuous thread blade 3 are the blade blade tip 4 that puts the first edge on a knife or a pair of scissors.
Multiple big blades 2 of spiral are set along anchor pole 1 is spaced apart, and continuous thread blade 3 is equal pitch thread, knot
Structure is simple, pierces effect good.
The softer area of the soil properties such as clay, first screw anchor is vertically driven underground to continuous thread blade-section, Ran Houan
Drilling equipment is filled, screw anchor is pierced into underground to requiring position using drilling equipment.
The harder area of the soil properties such as loess, sand, gets first with rig and draws hole, and drawing hole depth will be so that the spiral shell squeezed into
Rotation earth anchor continuous thread blade-section can be completely screwed into, and then installed drilling equipment, carried on the body using drilling and pierce screw anchor
Underground is to requiring position.
Above content is to combine specific preferred embodiment further detailed description of the utility model, it is impossible to
Assert that embodiment of the present utility model is only limitted to this, for the utility model person of an ordinary skill in the technical field
For, without departing from the concept of the premise utility, some simple deduction or replace can also be made, should be all considered as
Belong to the utility model and determine scope of patent protection by the claims submitted.
