Abstract
Description
Technical Field
[0001] This utility model relates to the field of building construction technology, and particularly to the field of pile foundation engineering technology, specifically referring to a prefabricated irregular pile that is both anti-uplift and anti-sinking. Background Technology
[0002] Building construction refers to the production activities during the implementation phase of an engineering project. It is the process of building various types of structures, or the process of turning the lines on design drawings into a physical object at a designated location. It includes foundation construction, main structure construction, roofing construction, and decoration construction.
[0003] Pile foundation engineering is a type of foundation engineering that transfers the load of a building or structure from its superstructure to deeper, harder, less compressible soil or rock layers through the piles, thereby meeting the load and deformation requirements of the superstructure or components. The piles used in pile foundation engineering are load-bearing components that transfer all or part of the building's load to the foundation soil and possess a certain rigidity and bending resistance. They are generally of equal cross-section at the top and bottom, with the cross-sectional dimension much smaller than its length. The bearing capacity of the pile foundation is provided through end pressure and side friction. For example, anti-sinking piles provide bearing capacity through end pressure and side friction, while tension piles provide bearing capacity through side friction.
[0004] However, existing piles provide the bearing capacity of the pile foundation through pile end pressure and pile side friction, and the bearing capacity of the pile foundation is sometimes insufficient and difficult to meet the usage requirements.
[0005] Therefore, it is desirable to provide a pile that can resist both uplift and settlement, and whose bearing capacity is improved to meet the application requirements. Utility Model Content

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0031] Please see Figure 1 As shown, in a specific embodiment of the present invention, the prefabricated irregular pile of the present invention, which is used for both pull-out resistance and sinking resistance, includes a vertical pile body 1. The upper end face and the lower end face of the vertical pile body 1 are both horizontally arranged and spaced apart from each other. The upper end of the vertical pile body 1 gradually increases in size from the lower end of the vertical pile body 1 upward and outward.
[0032] The lower end face of the vertical pile body 1 may be located directly below the upper end face of the vertical pile body 1, or it may not be located directly below the upper end face of the vertical pile body 1, for example, to the left, to the right, to the front, or to the back, etc. In a specific embodiment of this utility model, the lower end face of the vertical pile body 1 is located directly below the upper end face of the vertical pile body 1.
[0033] The upper end of the vertical pile body 1 gradually increases in size from the lower end of the vertical pile body 1 upwards and outwards. This increase can be linear (with a constant rate of increase) or non-linear (with a varying rate of increase). In a specific embodiment of this utility model, the upper end of the vertical pile body 1 increases linearly from the lower end of the vertical pile body 1 upwards and outwards, meaning that there is a continuous transition between the end face of the lower end of the vertical pile body 1 and the end face of the upper end of the vertical pile body 1.
[0034] The cross-section of the vertical pile body 1 can have any suitable shape. In a specific embodiment of this utility model, the cross-section of the vertical pile body 1 is circular.
[0035] The vertical pile body 1 can have any suitable shape. In a specific embodiment of this utility model, the vertical pile body 1 is an inverted frustum-shaped cone.
[0036] The vertical pile body 1 can be made of any suitable material. In one specific embodiment of this utility model, the vertical pile body 1 is a reinforced concrete pile body. In another specific embodiment of this utility model, the vertical pile body 1 is a metal pile body.
[0037] The metal pile body can be any suitable material. In another specific embodiment of this utility model, the metal pile body is a steel pile body.
[0038] The metal pile body can have any suitable shape. In another specific embodiment of this utility model, the metal pile body is a metal truss pile body.
[0039] The metal truss pile body can be made of any suitable material. In another specific embodiment of this utility model, the metal truss pile body is a steel truss pile body.
[0040] The specific embodiment of the present invention described above can be used as an anti-sinking pile, and its pile foundation bearing capacity composition diagram is shown below. Figure 2 As shown, when a specific embodiment of the present invention described above is reversed, as... Figure 3 As shown, it can be used as an anti-tension pile, and its pile foundation bearing capacity composition diagram is as follows. Figure 4 As shown.
[0041] When using, please refer to Figure 5 As shown, taking the use of a truck crane 3 to hoist precast piers on both sides of the foundation pit as an example, due to insufficient bearing capacity of the foundation, it is necessary to... Figure 1 The precast irregular-shaped piles shown are driven or pressed in as anti-sinking piles for the truck crane 3. If the outriggers of the truck crane 3 are about to lift off the ground, then... Figure 1 The precast irregular piles shown are inverted (i.e., as shown in the figure). Figure 3(As shown) Driven or pressed in, used as an anti-uplift pile for truck crane 3, the outriggers of truck crane 3 can be locked to the anti-uplift pile by clamps.
[0042] Therefore, this utility model provides a precast irregular pile that can be used for both uplift and settlement resistance. When the irregular pile is upright, i.e., the top is larger than the bottom, the irregular pile is a settlement resistance pile that bears the downward load; when the irregular pile is inverted, i.e., the top is smaller than the bottom, the irregular pile is an uplift resistance pile that restrains the upward load.
[0043] The advantages of this novel irregular-shaped pile are that the pile foundation bearing capacity is provided not only by the pile end pressure and pile side friction, but also by the pile side pressure. The decomposition of the pile side pressure generates vertical bearing capacity, and as the pile side pressure increases, the pile side friction also increases, which is particularly beneficial for improving the bearing capacity of pull-out piles that rely solely on pile side friction. The irregular-shaped pile provided by this invention has a higher pile body utilization rate and a higher pile foundation bearing capacity. The precast pile material can be reinforced concrete or metal. When using metal materials, the pile body can have a truss system. When the precast metal irregular-shaped pile is used as a temporary foundation, it can be pulled out and reused after use.
[0044] In summary, the precast irregular pile of this utility model, which is used for both uplift and settlement resistance, can resist both uplift and settlement, and the bearing capacity of the pile foundation is improved to meet the usage requirements. It has an ingenious design, simple structure, easy manufacturing, and low manufacturing cost, making it suitable for large-scale promotion and application.
[0045] Therefore, it is evident that the objective of this utility model has been fully and effectively achieved. The function and structural principles of this utility model have been demonstrated and explained in the embodiments. Without departing from the stated principles, any modifications can be made to the implementation methods. Therefore, this utility model includes all modified embodiments based on the spirit and scope of the claims.
