Abstract
Description
Technical Field
[0001] The utility model relates to a steel pipe pile, and more specifically, the present disclosure relates to a steel pipe pile capable of overcoming soft soil. Background Art
[0002] Concrete piles are made of concrete (including ordinary reinforced concrete and prestressed concrete). Compaction piles are formed by pressing or driving a steel pipe with a plug, a valve or a cone head into the ground to compact the soil layer to form a hole, and then filling the hole with fillers such as lime soil and sand and gravel. In building construction, in order to ensure the stability of the foundation, concrete piles are needed. In traditional construction on soil layers and rock layers, concrete piles can play a good role. However, when constructing on a soft soil base, using concrete piles will result in insufficient bearing capacity and difficult construction. At this time, steel pipe piles are needed to obtain sufficient bearing capacity. However, traditional steel pipe piles are generally used for compaction piles, and their structures are not very suitable for concrete fillers. In order to obtain greater bearing capacity and improve construction quality, filling the modified steel pipe piles with concrete will achieve unexpected effects on special bases with soft soil, high water content and high sand content. Summary of the Utility Model
[0003] The purpose of the present disclosure is to disclose a steel pipe pile capable of overcoming soft soil based on existing deficiencies. By using multiple outer sleeves arranged at intervals to form a channel between the outside of the outer sleeve and the outer cylinder cavity, when the compaction pile is inserted, the concrete can not only fill the entire outer cylinder cavity, but also flow out between multiple outer sleeves to form tumor-like blocks at the outflow part, making the entire compaction pile in the shape of a sugar-coated haws, thus achieving the purpose of solving the reinforcement of the underlying soft foundation.
[0004] In order to achieve the invention purpose of the present disclosure, the following technical solutions are disclosed in this application:
[0005] A steel pipe pile for a high-fill airport capable of overcoming soft soil, comprising an outer sleeve and a cylinder body. An outer cylinder cavity is provided inside the outer sleeve.

A cavity is provided inside the cylinder body. A conical tip is provided at the lower end of the cylinder body. The lower part of the inner cylinder provided in the lowermost outer sleeve is located inside the cavity below it.

[0009] For the steel pipe pile capable of overcoming soft soil, both the outer sleeve and the cylinder are made of steel.
[0010] Through the above disclosure, the beneficial effects of the present disclosure are as follows:
[0011] For the steel pipe pile capable of overcoming soft soil described in the present disclosure, channels are formed between the outside of the outer sleeve and the outer cylinder cavity by multiple spaced outer sleeves.
