Description

Technical Field

[0001] The utility model belongs to the technical field of building engineering piles, and in particular relates to a building engineering pile. Background Art

[0002] In modern buildings, the foundation of a building needs to be composed of foundation piles (also called foundation piles). Its usual structure is that several concrete piles deep into the ground jointly support a cap, forming a supporting unit of the building.

[0003] There are many types of construction engineering piles in the prior art. After searching, for example, the Chinese utility model patent with application number CN202021599037.8 discloses "a construction engineering pile". In this scheme, "it includes a pile body, the top of the pile body is connected to a load-bearing platform, the bottom of the pile body has an end cap, the pile body is hollow, a plurality of support rods are arranged in the pile body, and the plurality of support rods are arranged along the length direction of the pile body. The side wall of the pile body is provided with through holes for the plurality of support rods to extend and retract into the soil, and a pushing assembly for pushing the support rods to extend into the soil is arranged in the pile body. The arrangement of the end cap can facilitate the pile body to be driven into the soil. When the pile body is driven into the soil, a support rod is added to the pile body so that the support rod slides in the through hole, and the support rod is pushed out of the soil by using the pushing assembly, so that the support rod can be inserted into the soil, so as to increase the contact surface between the engineering pile body and the soil, and enhance the firmness between the pile body and the soil".

[0004] The above scheme solves the problem that "during construction, before the construction workers drive the foundation piles into the underground soil, they first drill holes on the ground, then put the foundation piles into the pre-drilled holes, and finally pour concrete into the foundation piles. However, at this time, there will be gaps between the engineering piles and the surrounding soil, so that the connection between the engineering piles and the surrounding soil is not tight and firm." It has certain practicality, but the above scheme still has shortcomings in specific use. The above scheme needs to be fixed by rotating the rotating rod, but there are multiple slurry holes on the pile body. When the pile body is embedded in the ground, some soil can enter the interior of the pile body from the slurry holes, thereby affecting the normal use of the bearing at the bottom end of the rotating rod, and then causing the rotating rod to be unable to be used normally, which needs further improvement;

[0005] Therefore, the utility model provides a construction engineering pile to solve the above-mentioned shortcomings. Utility Model Content
