Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
Embodiment 1
As shown in Figure 1, a kind of compressive pile, comprises pile body 1, and described pile body 1 is formed by connecting by the some sections of pile bodies 2 that sectional area diminishes successively from top to bottom, and the junction of every two adjacent pile bodies 2 forms stage portion 3, is provided with some dowels 5 in described pile body 1.
Preferably, the cross section of pile body 2 is square, H-shaped, triangle, circle, hexagon or octagon.The sectional area being positioned at the pile body 2 at pile body 1 top is 4-10:1 with the ratio of the sectional area of the pile body 2 be positioned at bottom pile body 1.Plane residing for the surface of stage portion 3 is vertical with the axial line of pile body 1.The height of each pile body 2 is identical.
Preferably, the two ends of pile body 1 are fixed with some attaching nuts 4, are provided with some dowels 5 in described pile body 1, and the two ends of dowel 5 are fixedly connected with the attaching nut 4 at pile body 1 two ends respectively.As shown in Figure 3, form chuck 6 bottom attaching nut 4 after reducing, rear formation boss 7 is expanded at the two ends of described dowel 5, and described boss 7 is with chuck 6 snap-fit engagement thus dowel 5 is fixedly connected with attaching nut 4.
Those skilled in the art are to be understood that, pile body 1 represents a complete stake, he can be an independent pile, also can be that many piles are axially connected to form the pile body 1 with certain length, as for the method for attachment of pile body, be then the common practise of those skilled in the art, have the stake of end plate end plate can be adopted to weld thus axially connect, the stake of end-plate-free can adopt connector shaft to connection.
As shown in Figure 2, pile body 1 can many be formed by connecting, thus reach the length of needs, the material connecting pile body 1 can be connector 100, the patent that the concrete structure of connector and operating principle are applied for before seeing the applicant.If application number is 201510314380.0; 200810060180.7; 200810060181.1 patent.Because connector is prior art, therefore repeat no more herein.
The advantage of the application is, when guaranteed strength, effectively can save material, reduce unnecessary material consumption.Table 1 is pile shaft force table under load at different levels.Wherein, load force and axle unit of force are KN, and the DU of pile body is m.
Pile shaft force table under table 1 load at different levels
Fig. 4 is pile shaft force figure under the loads at different levels according to table 1 drafting, can directly draw according to table 1 and Fig. 4, pile body more down time, suffered axle power is less, therefore, existing prismatic preformed pile wastes greatly, and the pile body 1 of the application can obtain the saving of material when guaranteed strength.
The from top to bottom that is all load of all loads on stake top all to be born responsibility load by stake, the power of resistance to compression bearing peg is from stake periphery frictional force, so the bearing capacity size of stake is again the frictional force quality coming from a periphery soil, the better bearing capacity of frictional force of stake periphery is larger, stage portion 3 between the pile body 2 of the application forms bearing support power, thus improves the load-carrying properties of pile body 1.The stage portion 3 of this compressive pile is formed vertically successively, thus makes stage portion 3 be arranged in different soil depths and soil property, and soil property at different levels can play resistance to compression support effect to pile body 1, substantially increases compressive property.
Embodiment 2
