High-strength concrete-filled steel tube precast pile

Abstract

The invention discloses a high-strength concrete-filled steel tube precast pile. The high-strength concrete-filled steel tube precast pile comprises a precast pile body, wherein steel sleeves sleeve the upper end and the lower end of the surface of the precast pile body; two sides of the lower end of the surface of the precast pile body are movably connected with fixed inserting blocks; and the ends, which are positioned in an inner cavity of the precast pile body, of the fixed inserting blocks are fixedly connected with limiting blocks. The precast pile body is driven into the ground, then a pile driver impacts a guide rod downwards, when moving downwards, the guide rod drives limiting pulleys to move, the limiting pulleys slide downwards in inner cavities of limiting chutes, thus, the limiting blocks are driven to move, the limiting blocks drive the fixed inserting blocks to move towards the outside of the precast pile body, the fixed inserting blocks can be inserted in soil, and as a result, the stability of the precast pile body is improved, the strength of the precast pile body is improved, and the problems that an existing concrete precast pile for a building is not fixed firmly and is easy to shake, potential safety hazards exist, and the engineering quality cannot be ensured are solved.

Description

technical field [0001] The invention relates to the technical field of building prefabricated piles, in particular to a high-strength steel pipe concrete prefabricated pile. Background technique [0002] Civil engineering refers to the planning, construction, and maintenance of all infrastructure related to water, soil, and culture. At present, general civil engineering projects include: housing, roads, water, drainage, flood control, and transportation, including residential buildings and public buildings. , structures and other constructions, such as precipitation, earth excavation, foundation laying, pouring of columns, beams, slab walls and other enclosure structures and masonry works, as well as supporting steel bars, simple decoration, etc., a large number of foundation piles are required for the construction of civil works , foundation piles are also called concrete prefabricated piles, and foundation piles are generally used as the foundation for engineering construc...
