[0002] A construction project refers to an engineering entity formed by the construction of various types of buildings and their ancillary facilities and the installation of supporting lines, pipelines, and equipment. Construction piles are one of the commonly used facilities in construction projects. They are mainly used as basic devices driven into the soil to support the upper buildings. Existing construction piles mainly include a pile body and a pile tip. The pile tip is installed at the bottom of the pile body. When in use, the pile body is struck and the pile tip is used to move downward in the soil to perform work.

[0003] Existing construction piles mainly include concrete structures and steel structures, and their structures are not much different. The pile body is a tubular structure and is inserted into the soil. Due to the poor connection between the pile body and the soil layer, its seismic resistance is low. When an earthquake occurs, it is easy to separate from the pile body due to the shaking of the soil layer, thereby reducing the stability and safety of the construction piles. Utility Model Content

The top of the inner tube pile 5 is fixedly connected with a cover plate 6, and the cover plate 6 covers the top of the outer tube pile 1. Through the insertion of the inner tube pile 5 and the setting of the bottom abutment ring 52, the connecting rod 3 is squeezed, so that the connecting rod 3 passes through the outside of the outer tube pile 1, thereby improving the connection effect between the device and the soil layer, and then improving the overall anti-seismic effect of the device.

[0029] Furthermore, step holes are evenly arranged on the circumference of the outer tube pile 1, and connecting rods 3 are inserted into the inside of the step holes. The top of the outer tube pile 1 is fixedly connected to the limiting column 11. Positioning holes are arranged on the circumference of the cover plate 6, and the limiting column 11 is inserted into the inside of the positioning holes. The height of the limiting column 11 is equal to the thickness of the cover plate 6. Through the connection between the cover plate 6 and the limiting column 11, a limiting function is played to ensure the alignment of the second casting hole 41 and the third casting hole 51, thereby facilitating the subsequent extrusion and pouring.

[0030] Furthermore, second casting holes 41 are evenly opened on the circumference of the center pile 4, and third casting holes 51 are evenly opened on the circumference of the inner tube pile 5, and the corresponding second casting holes 41 and the third casting holes 51 are on the same axis. The center of the center pile 4 is a hollow structure, and an abutment ring 52 is provided at the bottom of the inner tube pile 5, and the abutment ring 52 is a conical structure. Through the extrusion of the conical surface of the abutment ring 52, the step ring 33 and the connecting rod 3 can slide, so that the connecting rod 3 passes through the outside of the outer tube pile 1. The centers of the inner tube pile 5 and the abutment ring 52 are both hollow structures. The opening of this structure facilitates the circulation of concrete during subsequent pressurized pouring, thereby improving its overall strength. At the same time, the overflow of concrete improves the contact effect and connection effect with the soil layer.

[0031] Furthermore, a first casting hole 31 is provided at the center of the connecting rod 3, and the first casting hole 31 corresponds to the third casting hole 51, an overflow hole 32 is provided on the outside of the connecting rod 3, a step ring 33 is fixedly connected to one end of the connecting rod 3, and an abutment surface 34 is provided above the step ring 33, the step ring 33 has a certain magnetism, and in a contracted state, it contacts with the outer wall of the center pile 4 to avoid sliding of the connecting rod 3 when the outer tube pile 1 is inserted, the connecting rod 3 and the outer tube pile 1 are in a limited sliding connection, the diameter of the abutment surface 34 is larger than the diameter of the connecting rod 3, when the inner tube pile 5 is inserted between the outer tube pile 1 and the center pile 4, the connecting rod 3 penetrates to the outside of the outer tube pile 1, through the setting of this structure, the stability of the insertion of the outer tube pile 1 is improved, and the stability of the connecting rod 3 is improved by the connection between the soil layer, and at the same time, through the opening of the overflow hole 32, the concrete overflows under the extrusion state, further improving the contact and connection with the soil layer.

[0032] Working principle: The outer tube piles 1 used in this application are all products that can be directly purchased on the market. Their principles and connection methods are existing technologies well known to those skilled in the art, so they will not be repeated here. When the utility model is in use, the connecting rod 3 is first stored inside the outer tube pile 1, and the outer tube pile 1 is further operated so that the outer tube pile 1 is inserted into the soil, and the inner tube pile 5 is further inserted. The abutment surface 34 is squeezed by the abutment ring 52 so that the connecting rod 3 penetrates to the outside of the outer tube pile 1 to achieve the insertion of the soil layer, further improving the stability of the outer tube pile 1. At the same time, in the later stage, concrete is squeezed and poured in the center of the center pile 4, which can flow through the second casting hole 41, the third casting hole 51 and the first casting hole 31, and overflow through the overflow hole 32, thereby improving the connection effect between concrete and soil, and further improving the strength and stability of the device.
