Integrated foundation with integrally formed pile platform

Abstract

The invention relates to an integrated pile with an integrally formed pile platform, and belongs to the field of construction engineering. An integrated foundation with an integrally formed pile platform comprises a pile body and a positioning member; the pile body comprises a limiting part, a reinforcement cage and a prefabricated solid column structure, the prefabricated solid column structure is located at the center of the pile body, the reinforcement cage is connected to the outer ring of the prefabricated solid column structure and extends in the axial direction of the prefabricated solid column structure, the limiting part is arranged at the top of the pile body, the limiting part with the outer diameter larger than the outer diameter of the reinforcement cage is coaxial with the reinforcement cage, and longitudinal reinforcements of the reinforcement cage extend out of the top of the pile body; the positioning member is a prefabricated positioning member and is provided with astepped reserved hole in the axial direction, and the limiting part is clamped in the reserved hole; the pile body and the positioning member form the whole pile by pouring concrete. The integrated foundation has the advantages that the situation of pile position deviation after piling is avoided; the insufficiency of pile top strength caused by the formation of a weak material layer is avoided; the single-pile bearing capacity is guranateed; the quality defects of pile breaking, sinking and mud carrying caused by the external force of a soft, loose and flowing rock stratum are avoided.

Description

technical field [0001] The invention relates to an integrated pile formed integrally with a pile platform, which belongs to the field of construction engineering. Background technique [0002] During the construction of traditional cast-in-situ piles, the following problems generally exist: 1) After pile driving, the pile position is found to be out of position. 2) After the pile hole is formed, concrete is poured into the pile hole. Since the coarse aggregate in the concrete is heavier than the cementitious material, in the case of vertical pouring and tamping, the coarse aggregate will inevitably sink, and the cement and fine aggregates will gather A weak material layer, i.e. laitance, is formed at the top, resulting in insufficient strength of the pile top; before the construction of the next process, piles must be drilled again to remove the laitance. 3) When the laitance is not cleanly removed, the pile is connected to the cap, and there is a weak layer of strength at ...

2) After the pile hole is formed, concrete is poured into the pile hole. Since the coarse aggregate in the concrete is heavier than the cementitious material, in the case of vertical pouring and tamping, the coarse aggregate will inevitably sink, and the cement and fine aggregates will gather A weak material layer, i.e. laitance, is formed on the top, resulting in insufficient pile top strength; before the construction of the next process, the pile must be drilled again to remove the laitance

3) When the laitance is not cleanly removed, the pile is connected to the cap, and there is a weak layer of strength at the connection part; in the process of force transmission, the bearing capacity of the single pile is affected due to insufficient section strength
