The specific embodiment
Fig. 1 is the structural representation according to the screw pile of an embodiment of the present utility model.Referring to Fig. 1, screw pile 100 of the present utility model comprises pile body 101 and leading section 102.The interval arranges helical blade 103 and 104 on pile body 101.Pile body 101 can be solid barred body, can be also hollow body.It is non-circular that the cross section also can be, shapes such as rectangle or hexagon.Leading section 102 is tapered or tilt, and is arranged on the front end of pile body 101.Leading section 102 both can be installed on pile body 101, also can be integrally formed with pile body 101.
According to an embodiment of the present utility model, helical blade 103 and 104 is uniform in the variation on the direction of pile body.Particularly, helical blade comprises a middle sampan line, and its implication is that this line is on described blade, and perpendicular to the surface of pile body.Like this, the variation of middle sampan line in the vertical direction, more specifically, the variation of the intersection point in the vertical direction of middle sampan line and pile body surface has reflected the variation of helical blade in the vertical direction.In the present embodiment, the variation of middle sampan line in the vertical direction is uniformly, or perhaps at the uniform velocity.Such screw pile has best mechanical structure and screws ability.
According to an embodiment of the present utility model, pile body 101 comprises first paragraph and second segment, and wherein first paragraph is different from second segment.For example, pile body 101 epimeres are cylindrical stakes, and hypomere is barrette; Perhaps epimere has the diameter larger than hypomere.This is mainly some ways of taking in order to adapt to different geological conditionss.For some specific environment, has very outstanding effect.
According to an embodiment of the present utility model, leading section 102 is optional parts.That is to say, in some cases, screw pile 100 can not have leading section 102.The effect of leading section 102 is to utilize the profile auxiliary screw stake of its inclination to be rotated into underground.Another situation is, when pile body 101 is tubular structures, inserts tapered or a tilt rotary head during construction from the body of pile body 101, so also needn't leading section 102 be set on pile body.
The pile body 101 of screw pile 100 closes on a part on top and also is provided with a perforated portion 110.Perforated portion 110 comprises a jut and is arranged on hole on this jut.Should be noted that and also can be provided with identical perforated portion with the opposite side of the pile body of perforated portion 110 symmetries.Perforated portion 110 is used for being connected with the screwing device that drives the screw pile rotation.
On the pile body 101 of screw pile 100, the top of perforated portion 110 also is provided with adjusting hole 120.According to an embodiment of the present utility model, be provided with altogether the adjusting hole at 120 °, three intervals on pile body 101.Adjusting hole can be admitted the adjustment bolt.Screw pile need to be connected with the braced structures on it.After the braced structures pillar extend in screw pile, the adjustment bolt that passes adjusting hole by adjustment can be adjusted the position of pillar, and the pillar that guarantees to be installed on screw pile is consistent after adjusting, with convenient other parts that braced structures further is installed.
According to an embodiment of the present utility model, the braced structures pillar is installed to screw pile and the adjustment bolt by passing adjusting hole fixing after, further turn to wait by the hole electricity consumption on perforated portion 101 and turn null device and punch equally on pillar.Then, by the bolt that passes the hole of getting on hole on perforated portion 101 and pillar, that screw pile and pillar is further fixing.It may be noted that this method has been utilized is screwed into hole on perforated portion 101 when underground with screw pile, simple and convenient, and firm in structure.
As mentioned in background technology, a technical barrier in this area is exactly the structure that how to customize screw pile reaching required bearing capacity, and can conveniently install.A lot of parameters of screw pile can exert an influence to this.For example: opening (pitch) of the diameter of long, the pile body of stake, blade size, blade etc.The length of blade also can be multiple, all has screw thread as whole pile body, and perhaps the part pile body has screw thread, is only perhaps the single track screw thread.Blade itself also can have multiple variation, as single fin helical blade, has two fin helical blades of two parallel blades, even three fin helical blades.For example, if the blade diameter selection is larger, pitch is also smaller, and the bearing capacity of screw pile is better.Yet this had both increased cost, also difficulty was increased when underground screw pile is screwed into.In prior art without any about how customizing the content of screw pile structure.In actual applications, those skilled in the art select according to the experience of oneself, then finally determine by the test pile experiment of reality.This both expended time in, and result is only also to meet the demands, and often is high expensive.
The utility model people of this case is through long-term observation and test discovery, and for the bearing capacity of screw pile, the length of screw thread does not have too much influence.Fig. 2 is the structural representation of a kind of screw pile of the prior art.As shown in Figure 2, this screw pile comprises pile body 201, leading section 202 and endless spiral 203.The blade 203(that is provided with continuous rotation on the under ground portion of whole or most of screw pile is screw thread).
With regard to the present general understanding in this area, the bearing capacity of screw pile shown in Figure 2 will be better than screw pile shown in Figure 1 greatly.And this is a kind of prejudice of mistake in fact.Fig. 1 and screw pile shown in Figure 2 are more or less the same aspect bearing capacity.In some cases, the bearing capacity of screw pile shown in Figure 1 even is better than screw pile shown in Figure 2.Fig. 3 is the screw pile supporting capacity contrast schematic diagram of twayblade screw pile and continuous blade.Wherein, each blade in twayblade is the single track helical blade, and its blade only rotates a circle around pile body.As shown in the figure, D is identical at blade diameter, and also in identical situation, twayblade spiral bearing capacity of pile is better than the screw pile of continuous blade to pile length L.Yet processing maintenance difficulties and cost between both can't be mentioned in the same breath.Therefore, with regard to practical application, screw pile shown in Figure 1 is more economic and practical.This is very significant discovery for this area.
For as shown in Figure 1 screw pile for, be the single track helical blade at each blade, and the variation of helical blade in the vertical direction is also under uniform prerequisite, structural parameters how to optimize screw pile are still also difficult problems.As shown in Figure 1, following at least structural parameters may exert an influence to the performance of screw pile:
A: the blade of screw pile is apart from the length on stake top;
B: the lower blade of screw pile is apart from the length of pile top;
C: the distance between two adjacent blades of screw pile;
D: the diameter of screw pile pile body;
D: the diameter of screw pile blade;
L: stake is long; And
T: blade is the distance of upper shed in the vertical direction, i.e. pitch.
In above these parameters, stake is long is an important parameter, and it has determined that directly stake screws in a underground degree of depth, has also determined to a great extent the indexs such as the deadweight of stake and cost.
In the situation that pile length is certain, the optimization of other parameters is more difficult.In prior art without any can be for reference content.The utility model people of this case finds, the ratio between the distance c between two adjacent blades of screw pile and the diameter D of screw pile blade, i.e. and ratio c/D between blade pitgh and blade plays a part very crucial to the vertical bearing capacity aspect of screw pile.
Fig. 4 is according to an embodiment of the present utility model, the ratio between the distance c between two adjacent blades of screw pile and the diameter D of screw pile blade and bearing capacity concern schematic diagram.In Fig. 4, blade pitgh and the ratio between blade diameter of curve 1-6 are respectively 1.02,2.03,3.05,4.07 and 6.10; The stake appearance with and the diameter D of blade also is 236 millimeters (mm).As can be seen from the figure, when c/D is between 2-6 the time, load is best.Preferably, when c/D is between 3-5 the time, the amplitude that load increases is better than the situation of expection far away.
Fig. 5 is according to an embodiment of the present utility model, in the situation of the diameter D of different screw pile blades, the ratio between the distance c between two adjacent blades of screw pile and the diameter D of screw pile blade and bearing capacity concern schematic diagram.In Fig. 5, black circle represents that the diameter D of screw pile blade is the screw pile of 236mm, and hollow square represents that the diameter D of screw pile blade is the screw pile of 176mm.Can find out from Fig. 5, when the ratio c/D between blade pitgh and blade was 2-6, the bearing capacity of screw pile was through after normalization, all 0.7, namely more than 70%.Excessive or when too small when the ratio of blade pitgh and blade diameter, all can reduce the bearing capacity of screw pile.Particularly, particularly when the ratio c/D between blade pitgh and blade was 3-5, situation about significantly promoting had obviously appearred in the bearing capacity of screw pile.The load-carrying properties of screw pile are optimum.Fig. 4 and Fig. 5 have illustrated the important of ratio between blade pitgh and blade together.
In order to further illustrate above-mentioned conclusion, can carry out reference with Fig. 6.Fig. 6 is according to an embodiment of the present utility model, concerns schematic diagram between screw pile blade diameter and anti-pulling capacity.As can be seen from Figure 6, in the situation that other conditions are identical, along with the increase of blade diameter, the anti-pulling capacity of screw pile progressively promotes.Yet the increase of screw pile blade diameter will greatly affect the cost of screw pile; Simultaneously, also affect the ability that is rotated into ground of screw pile.After surpassing certain limit, blade is larger, and its energy that is rotated into the required cost in ground is just more, screw pile is screwed in underground just more difficult.Therefore, can not simply improve bearing capacity by the diameter that increases blade.This also further illustrates the importance of Fig. 4 and Fig. 5 conclusion.In the situation that does not increase blade diameter, by adjusting the ratio between blade pitgh and blade, can promote the spiral bearing capacity of pile equally.
Another the important parameter that affects the screw pile performance be blade in the vertical direction upper shed apart from t, i.e. pitch.Even for the single track helical blade, it also can be seen as a kind of special pitch.Different from other parameters, pitch is the design parameter scope, rather than ratio.That is to say, what affect this parameter of pitch only has the geology soil regime, and is independent of other parameters of stake.According to an embodiment of the present utility model, the scope of the pitch of blade is 50-250 millimeter (mm).Preferable range is 60-150 millimeter (mm).
Another parameter is the ratio D/d between blade diameter D and pile body diameter d.This parameter has in fact directly determined the area that helical blade contacts with the soil.Based on same reason, this area is not to be the bigger the better.According to an embodiment of the present utility model, the scope of the ratio D/d between blade diameter and pile body diameter is 2-6, and preferable range is 3-5.
As for the length a of the blade of screw pile apart from the stake top, according to an embodiment of the present utility model, this distance should greater than 400 millimeters (mm), be preferably more than 600-800 millimeter (mm) at least.And the lower blade of screw pile is different different because of the leading section of stake apart from the length b of pile top.According to an embodiment of the present utility model, the lower blade of screw pile is arranged on pile body bottom, the bottommost before namely the diameter of stake begins to diminish.In some situation, lower blade may be smaller, and its main contribution is to promote to screw, and few to the bearing capacity contribution.At this moment, the adjacent blades of lower blade can separate certain distance with lower blade.
Screw pile is metal normally, as steel.According to an embodiment of the present utility model, screw pile adopts nonmetals to make.Nonmetals can reduce the use of steel, reduce costs.Especially, as mentioned in background technology, owing to can not carry out in advance the work such as dash blowdown when using screw pile, screw pile is easy to be subject to the impact of underground environment.For example, when using screw pile in the particular surroundings such as salt-soda soil, the screw pile of metal is very easy to be corroded and affects the stability of stake.Therefore, screw pile also can adopt treated corrosion resistant metal or nonmetals to make.
Adopting a difficult problem of nonmetals is intensity and the toughness that will guarantee screw pile.That is to say, the nonmetals that adopt should have and physical property like metal species, for example, and engineering plastics.Engineering plastics comprise many types, such as ABS, nylon, PBT etc.Yet engineering plastics itself can't directly be used, and must carry out modification to it, strengthen its engineering properties and chemical property, to meet the concrete application of screw pile.
