Description

Technical Field

[0001] The utility model belongs to the technical field of engineering construction, and specifically relates to an H-shaped steel column pile delivery connection structure. Background Art

[0002] For foundation pits with prefabricated pipe piles as foundation and H-shaped steel as columns, the design elevation of the top of the column is below the ground. The current pile driver cannot meet the construction requirements and cannot deliver the top of the column to the design elevation. At present, most of the columns in foundation pit support use lattice column bored pile foundation or steel pipe column bored pile foundation. During construction, the pile foundation is first drilled, then underwater concrete is poured, and finally the lattice column or steel pipe is implanted. This method does not require pile delivery; however, the existing pile driver for projects with prefabricated pipe piles as foundation and H-shaped steel as columns is not enough to meet the construction requirements, which will limit the application of H-shaped steel as columns. Other columns and column foundation types are selected, such as bored pile foundation lattice columns, bored pile foundation steel pipe columns, etc., and the construction period is long and the cost is relatively high. Foundation pit engineering is a temporary project, and investing too much cost is obviously not cost-effective. If a new type of pile driver can be developed, the method of using prefabricated pipe piles as the foundation and H-shaped steel as the columns can be widely used, which can ensure the safety of the foundation pit engineering while ensuring the economy of the project, it is particularly important.

[0003] Based on this, the utility model provides an H-shaped steel column pile delivery connection structure, which can carry out pile delivery operations on a foundation pit with prefabricated pipe piles as foundations and H-shaped steel as columns, with a short construction period and high efficiency.
