Concrete and induration formed composite type pile and its manufacture method

Abstract

The invention discloses a composite pile body formed by concrete and a concretion body and a construction method thereof; the composite pile body is formed by the different combination of the concrete pile body, a pile side concretion body formed by slurry sprayed from the pile side and a pile bottom concretion body formed by slurry sprayed from the pile bottom; the construction method comprises that: a hole is drilled to a preset depth by a driller; according to the need of a design proposal, the pile bottom concretion body is formed after slurry is sprayed from the pile bottom; the concrete is affused by lifting a drill stem, and the pile side concretion body with different shapes is formed by controlling the rotation of the drill stem and the spraying of the slurry; after the drill stem is lifted to the pile top and a height mark is designed, if the pile body is a reinforced concrete type composite pile body, a steel reinforcement cage also needs to be inserted to complete the construction of the composite pile body. The composite pile body formed by the concrete and the concretion body and the construction method can effectively improve the bearing capacity of the pile body and has high construction efficiency and high economical efficiency.

Description

Technical field: [0001] The invention relates to foundations in the technical field of construction and pile bodies in foundation engineering, in particular to a composite pile body formed of concrete and a consolidated body and a manufacturing method thereof. Background technique: [0002] In the construction of construction projects, the foundation acts as the foundation of the building and plays the role of transferring the load from the upper part of the building to the bearing layer. Due to the diversity of strata, the design unit can choose different strata as the bearing stratum according to the load on the upper part of the building, the geological conditions of the area where the building is located and the foundation construction technology. In foundation construction, it is unavoidable to encounter areas where the underlying structure contains one or more soil layers in soft soil layer, general soil layer, hard soil layer, sand layer or pebble layer. The design un...

Problems solved by technology

In foundation construction, it is inevitable to encounter areas where the underlying structure contains one or more soil layers in soft soil layer, general soil layer, hard soil layer, sand layer or pebble layer. The design unit will use the "Geological The stratum described in the Exploration Report” selects the appropriate pile type, but no matter what foundation treatment method is selected, there is such a contradiction in terms of the current development of foundation treatment technology: how to meet the current national and industry standards ( Regulations) to design theoretical data requirements, but also to maximize the characteristic value of the single pile bearing capacity, to ensure the economy of the foundation scheme, to avoid increasing the pile diameter, multiplying piles, or increasing the replacement rate when using composite foundations, etc. Emergence of the cost situation
