Abstract
The utility model discloses a three-point continuous screw pile foundation which comprises a tube body. The tube body is integrally columnar, one end of the tube body is conical, the side surface of the other end of the tube body is fixedly connected with a raised nut, and the outer side part of the tube body is provided with a continuous spiral blade. Through the spiral blade on the tube body, the structure form of traditional pile foundation section is changed, and the interactional mode between a pile and a soil body is changed, the pile and the soil interface are in mechanical occlusion, so that the characteristic of firmness of the pile is realized. The soil body at the side of the pile is extruded and compacted during the piling process, so as to form the nut after piling, the spiral blade is in close occlusion with the side of the pile foundation, so that the acting force distribution between the soil and the pile is adjusted, the stress allocation ratio and the stress diffusance of the soil body at the side of the pile are improved, the load at the end of the pile is reduced, the stress of the pile body and the stress of the soil body are consistent, and the stable performance, unsinkability and tensile performance of the pile foundation are further enhanced.
Description
Technical field
The utility model relates to a kind of pile foundation, especially a kind of 3 continous way screw pile bases.
Background technology
Existing solar power station construction and municipal administration, a plurality of industry construction field such as traffic (fence, flagpole, billboard, traffic indication board etc.) when doing underground foundation, normally excavate foundation ditch at the scene, ram base, assembling reinforcement cage and supporting template, cast-in-situ concrete, or bury prefabricated concrete stake backfill original soil then underground, thereby program is loaded down with trivial details, the job site is dirty and messy, and the construction period of known technology is very long, need long-term curing concrete, because of material wide in variety, tissue inconvenience, logistics cost strengthens, part wild environment constructional difficulties, working area is big, the heavy damage vegetation, can't construct by season and weather effect, be subject to special geologic condition and can't construct, increase construction cost, therefore, need a kind of more advanced pile foundation, simplify the pile foundation construction program.
Summary of the invention
The utility model provides a kind of 3 continous way screw pile bases according to building the loaded down with trivial details defective of construction sequence in the above-mentioned prior art, and the utility model is achieved by following technical proposals:
Comprise body, described body integral body is column, tapered, the multiple tooth shape of an end of described body, cross, in-line, the degree of lip-rounding of cutting sth. askew or truncation degree of lip-rounding drill bit formula metal construction, and be fixed with the outer lug nut on the side of the described body other end; The Outboard Sections of body is provided with continuous helical shape blade one.
Preferably, also be provided with anticorrosive coat outside the described pipe shaft.
Preferably, an end of described body is multiple tooth shape, cross, in-line, the degree of lip-rounding of cutting sth. askew or truncation degree of lip-rounding drill bit formula metal construction.
Preferably, be fixed with the outer lug nut bore on the side of the described screwed pipe body other end.
The screw pile basis that the present invention program provides, changed the structure form of conventional piles basis section by the spiral vane on the body, adjusted the distribution of forces between soil and the pile foundation, the soil body stress of pile foundation side is shared when, and the stress diffusance improves, pile foundation end load reduces, make the pile foundation body stressed harmonious with earth stress, changed interactional pattern between the stake and the soil body, stake has constituted the mechanical type interlock with the pedosphere face, its more firm characteristics are achieved, the piling process king-pile side soil body is squeezed, compacted effect, the piling back stake side soil body forms nut, spiral vane and the tight interlock of pile foundation side, adjusted the distribution of forces between soil and the stake, stake side soil body stress is shared stress diffusance raising when, and a stake end load reduces, make pile body stressed harmonious, further strengthen the firm performance of pile foundation with earth stress, unsinkability energy and anti-pulling performance.
Description of drawings
Accompanying drawing described herein is used to provide further understanding of the present invention, constitutes the application's a part, does not constitute to improper qualification of the present invention, in the accompanying drawings:
Fig. 1 is the utility model example structure schematic diagram;
Fig. 2 is the utility model embodiment vertical view.
The specific embodiment
Describe the present invention in detail below in conjunction with accompanying drawing and specific embodiment, be used for explaining the utility model in this illustrative examples of the present utility model and explanation, but not as to qualification of the present utility model.
Embodiment 1
As depicted in figs. 1 and 2, one bottom surface diameter is the steel cylindrical tube 1 of 50mm, the body bottom of this steel pipe 1 is conical, the part on close top on steel pipe 1 body, be welded with three nuts 2, three nuts 2 evenly distribute on the circumference of steel pipe 1 section, and the body section circular arc radian between the described adjacent nut 2 is 120 degree; Below nut 2, also be provided with spiral vane 3 one, this spiral vane 3 is the lip-deep projection of steel pipe 1 body, this projection is around body shape setting in the shape of a spiral from top to bottom.
One bottom surface diameter is the steel cylindrical tube of 1500mm, the body bottom of this steel pipe is conical, near the part on top, is welded with four nuts on the steel pipe body, four nuts evenly distribute on the circumference of steel pipe section, and the body section circular arc radian between the described adjacent nut is 90 degree; Below nut, also be provided with spiral vane one, this spiral vane is the lip-deep projection of steel pipe body, this projection is around body shape setting in the shape of a spiral from top to bottom.
Adopt the screw pile basis of the foregoing description scheme, because of having adopted the structure form of variable cross-section, satisfy distribution Regularity of Additional Stress and stress and shared the requirement of stiffness variation when, adjusted the distribution of forces between soil and the pile foundation, the soil body stress of pile foundation side is shared when, and the stress diffusance improves, pile foundation end load reduces, make the pile foundation body stressed harmonious with earth stress, changed interactional pattern between the stake and the soil body, stake has constituted the mechanical type interlock with the pedosphere face, its more firm characteristics are achieved, the piling process king-pile side soil body is squeezed, compacted effect, the piling back stake side soil body forms nut, and pile body screw thread (spiral vane) and the tight interlock of stake side soil nut have been adjusted the distribution of forces between soil and the stake, stake side soil body stress is shared when, and the stress diffusance improves, stake end load reduces, and makes pile body stressed harmonious with earth stress, further strengthens the firm performance of pile foundation, unsinkability energy and anti-pulling performance.
More than the technical scheme that the embodiment of the invention provided is described in detail, used specific case herein the principle and the embodiment of the embodiment of the invention are set forth, the explanation of above embodiment only is applicable to the principle that helps to understand the embodiment of the invention; Simultaneously, for one of ordinary skill in the art, according to the embodiment of the invention, the part that on the specific embodiment and range of application, all can change,
In sum, this description should not be construed as limitation of the present invention.
