Building foundation construction equipment and construction method

Abstract

The invention provides building foundation construction equipment. The building foundation construction equipment comprises a plurality of steel pipes and a plurality of impact cones, wherein the multiple steel pipes are different in diameter and form barrel bodies of construction guard barrels of foundation cast-in-place concrete piles, and the multiple impact cones correspond to the multiple steel pipes different in diameter and can be combined with the steel pipes different in diameter. Each impact cone comprises a cylindrical upper half part and a conical lower half part. Inner threads are arranged on the inner surfaces of the steel pipes. The diameters of the upper half parts of the impact cones are equal to the inner diameters of the steel pipes, and corresponding outer threads are arranged on the outer surfaces of the upper half parts of the impact cones, so that the upper half parts of the impact cones can be connected and fixed to the steel pipes through the threads. The maximum diameters of the lower half parts of the impact cones are equal to the inner diameters of the steel pipes.

Description

technical field [0001] The invention relates to construction equipment for concrete pouring piles used in building foundations. Background technique [0002] With the rapid development of my country's construction industry, in the construction process of many industrial buildings and civil buildings, different pile foundation structures are used for construction. The pile foundation technology has greatly strengthened the stability of the building structure and improved the structure of the building. [0003] The bearing capacity can effectively avoid uneven settlement. [0004] Concrete pouring pile is a basic structure often used in construction. It has the characteristics of strong adaptability, moderate cost, and simple construction. It has been widely used in highway and urban bridge construction. The construction technology and quality of concrete pile foundation are directly related to the engineering quality of the entire construction project. Good pile foundation...

Problems solved by technology

However, in the technical solution of this invention, since the pointed cone at the top of the casing is welded, it is necessary to take out the casing with the pointed cone from the pile hole when filling the pile hole, and then put other casings into the pile hole for filling. , so that on the one hand, the construction process will be increased, resulting in a decrease in construction efficiency, and additional construction equipment will be required; on the other hand, the removal and sinking of the casing will cause damage to the pile hole, thus affecting the construction quality
