Description

Technical Field

[0001] The utility model relates to the technical field of pile foundation casing, in particular to a high-strength pile foundation casing. Background Art

[0002] Casing is the process of bored piles. Due to the instability of the soil, it is very difficult to construct reinforced concrete retaining walls. Therefore, steel retaining walls are used to protect the bored piles to prevent hole collapse and avoid affecting the construction progress and safety. Common types include round and square shapes. They are widely used in pile foundation projects. Pile foundation casing has the function of protecting the pile foundation and providing strength and stability to the pile foundation.

[0003] At present, after the pile foundation casing is clamped and hoisted into the pre-excavated pit with the help of a vibrating hammer, the vibrating hammer will press the pile foundation casing into the soil with vibration force. However, the structural strength of the single-layer pile foundation casing is limited by the material. When the pile foundation casing is pressed into the soil layer, the pile foundation casing often bears the soil pressure and the lateral pressure of groundwater deep underground. The single-layer pile foundation casing is prone to deformation and damage under the double pressure, which affects the protection of the casing to the pile foundation. For this reason, we propose a high-strength pile foundation casing. Utility Model Content

[0004] The main purpose of the utility model is to provide a high-strength pile foundation casing, in which a core casing and an inner filling mechanism are arranged in the casing body to form a new pile foundation casing, which can be normally hammered into the ground for use. When the casing body and the core casing encounter soil pressure and the lateral pressure of groundwater, the three-layer structure of the pile foundation casing can form a strong cylinder, so that the pile foundation casing is not easily crushed by external forces, thereby improving the deformation resistance of the pile foundation casing, effectively ensuring the high-strength protection of the pile foundation casing for the pile foundation, and can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] Further, the length of the inner filling slot is the same as the length of the core filling tube, and eight groups of inner filling slots are opened on the surface of the core filling tube;
