Description

Technical Field

[0001] The utility model relates to the technical field of construction, in particular to a novel sword-groove type friction pile structure. Background Art

[0002] Friction piles refer to piles whose bottom is located in a softer soil layer. Their axial load is supported by the friction resistance of the pile side and the reaction force of the soil at the bottom of the pile. They are mainly used in foundations with very deep rock strata. Under the ultimate bearing capacity state, the pile top load is borne by the pile side resistance.

[0003] At present, in the prior art, a Chinese patent with announcement number CN214883585U discloses a sword-groove type friction pile structure. The device can maintain a uniform cross-section of the upper and lower parts of the pile body without affecting the strength of the pile body, and is not easy to break or be damaged through the sword-groove type pile body. However, in actual use, the device only relies on the sword-groove type grooves to increase the surface area of ​​the pile body to improve the utilization rate of the surface. This setting for improving the utilization rate of the surface cannot significantly improve the stability of the overall pile body in the soil. In view of this, we propose a new sword-groove type friction pile structure. Utility Model Content

[0004] The main purpose of the utility model is to provide a novel sword groove type friction pile structure, which can solve the problems raised in the above background technology.

[0005] In order to achieve the above-mentioned purpose, the utility model proposes a novel sword groove type friction pile structure, including a pile body, the pile body is provided with grooves on the sides thereof, and each side of the pile body is provided with two groups of grooves, a pointed plug is fixedly connected to the bottom of the pile body, the pile body is provided with through holes on the sides thereof, and an auxiliary mechanism is provided inside the pile body, and the auxiliary mechanism includes:

[0006] A sliding groove is provided below the side walls around the pile body, a sliding block is slidably connected inside the pile body, and a through hole 2 is provided on the sliding block which penetrates the sliding block. Through the setting of through hole 1 and through hole 2, the poured concrete can flow through through hole 2 to the area below the sliding block for continued pouring, thereby ensuring the overall stability of the pile body. Through hole 1 also facilitates the poured concrete to flow through through hole 1 into the soil around the pile body, thereby further ensuring the stability of the pile body in the soil.

[0007] Preferably, a fixing plate is fixedly connected below the sliding block, and the fixing plate is rotatably connected to a connecting rod.

[0008] Preferably, one end of the connecting rod away from the fixed plate is rotatably connected to a sliding plate, and one end of the sliding plate away from the connecting rod is in the shape of sharp teeth, and the sharp tooth-shaped arrangement facilitates the pile body to be quickly nailed into the soil.

[0009] Preferably, the sliding plate is slidably connected to the sliding groove, and a thin film is fixedly connected to the outside of the sliding groove. By pouring concrete into the pile body for pouring, the sliding block will be driven to move downward under the action of the gravity of the concrete. Under the action of the fixed plate, the connecting rod and the sliding plate, the downward movement of the sliding block will drive the sliding plate to move to the outside of the pile body through the sliding groove, so that the sliding block is inserted into the soil outside the pile body, thereby strengthening the stability of the pile body in the soil. At the same time, the provision of the thin film on the outside of the sliding groove makes it easy to keep the overall auxiliary mechanism in a relatively static state. When concrete is poured in, the downward movement of the sliding block will cause the sliding plate to pierce the thin film through its sharp tooth-shaped end, thereby allowing the sliding plate to be inserted into the soil outside the pile body.

[0010] Preferably, the through hole is arranged on the surface of the groove on the pile body, so that the poured concrete can quickly penetrate outward through the through hole.

[0011] Preferably, the fixed plates are provided with four groups, and the four groups of fixed plates are respectively fixedly connected at four directions below the sliding block. The fixed plates are provided with four groups, and each group includes two fixed plates. A connecting rod is rotatably connected between the two fixed plates, and sliding plates are rotatably connected on both sides of the connecting rod. This arrangement can make the pile body more stable and not loose when it is buried in the soil.

[0012] The utility model provides a novel sword groove type friction pile structure, which has the following beneficial effects:

[0013] (1) The novel sword groove friction pile structure is constructed by setting a sliding block, a connecting rod and a sliding plate. By pouring concrete into the pile body for pouring, the sliding block is driven downward by the gravity of the concrete. Under the action of the fixed plate, the connecting rod and the sliding plate, the downward movement of the sliding block drives the sliding plate to move to the outside of the pile body through the sliding groove, so that the sliding block is inserted into the soil outside the pile body, thereby strengthening the stability of the pile body in the soil.

[0014] (2) The novel sword-groove type friction pile structure is provided with through hole 1 and through hole 2, so that the poured concrete can flow through through hole 2 into the area below the sliding block for further pouring, thereby ensuring the overall stability of the pile body. Through hole 1 also facilitates the poured concrete to flow through through hole 1 into the soil around the pile body, thereby further ensuring the stability of the pile body in the soil.
