Assembled integral static pressure pile column

Abstract

The invention discloses an assembled integral static pressure pile column which comprises a pile guiding device, a pile body, a static pressure stress sleeve column and a bearing platform conversion layer. The pile guiding device is arranged at the bottom of the pile body. The bearing platform conversion layer is connected with the pile body and the static pressure stress sleeve column. The staticpressure stress sleeve column comprises an inner column and an outer column, and concrete grouting space is reserved between the inner column and the outer column. The square pile column is adopted and prefabricated in a factory, the integrated pile column can be directly subjected to static pressure to the corresponding position, the construction time and labor are saved, the construction process is reduced, and the bearing capacity of the pile body is improved. The assembled integral static pressure pile column is suitable for building structures such as assembled integral building foundations, assembled integral vertical underground parking garages, assembled integral underground space and assembled integral riverway retaining dams.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to an assembled integral static pressure pile. Background technique [0002] With the development of economy and society, high-rise buildings, underground space requirements, and foundation reinforcement technology are the focus and focus of my country's civil engineering, transportation engineering and other fields. Assembling integral static pressure piles to strengthen the foundation and underground engineering without support is a new technology for building foundation reinforcement and underground space support underpinning. Due to the use of prefabricated piles, the quality and integrity of the piles are guaranteed, and the process is simple and convenient. It is easy to operate and fast in construction speed, and can achieve the goals of saving materials, no vibration, no noise, small construction stress, and no pollution to the environment. The use of construct...

Problems solved by technology

[0003] The pile part of the assembled integral static pressure pile belongs to the soil-squeeze pile, and the soil-squeeze effect is obvious. On the one hand, the soil-squeeze effect can improve the side friction resistance of the engineering pile and increase the bearing capacity of the single pile, especially in areas where soft soil is widely distributed. The reinforced foundation is mixed with a certain thickness of compacted sand layer, the pile sinking is difficult, and the pile ends cannot reach the design elevation, which largely limits the application and promotion of the static pressure pile reinforced foundation
