Non-foundation post pressing pile implementation method

Abstract

The invention discloses a non-foundation post pressing pile implementation method. The ground between two existing foundations is non-foundation foundation soil. The non-foundation post pressing pile implementation method comprises the steps that two parallel counter-force beams are arranged between the two existing foundations; the counter-force beams and the existing foundations are fixedly connected; each counter-force beam is provided with a pile frame, and the two pile frames correspond to each other; a pressing pile is arranged between the two pile frames; a cross beam is arranged at the tops of the two pile frames, and a hydraulic jack is arranged on the cross beam and used for pressing the pressing pile into the non-foundation foundation soil till the top of the pressing pile is flush with the non-foundation foundation soil; and then the counter-force beams together with the pile frames, the cross beam and the hydraulic jack are dismantled from the existing foundations.

Description

technical field [0001] The invention relates to a special construction technology of civil engineering, and more specifically relates to a post-pile pressing method of an existing building structure on a foundation without a foundation. Background technique [0002] The post-pile pressing method on the existing building structure foundation of present all is to excavate the pile-pressing hole on the existing building-structure foundation, then in the pile-pressing hole pile is pressed in the foundation soil under the foundation. The premise of the pile pressing is: there must be an existing foundation at the pile pressing position, otherwise the pile cannot be pressed into the foundation soil. The reason is: when there is no foundation to press the pile, because there is no foundation in the place where the pile is pressed, the anchor rod of the fixed pile frame has no way to connect with the existing foundation, so the traditional method of static pressure pile with anchor ...

Problems solved by technology

The reason is: when there is no foundation to press the pile, because there is no foundation in the place where the pile is pressed, the anchor rod of the fixed pile frame has no way to connect with the existing foundation, so the traditional method of static pressure pile with anchor rod cannot press the pile to the foundation through the pile frame soil

[0003] With the needs of reconstruction and expansion of existing buildings and foundation reinforcement, piles must be pressed into the foundationless places. Using the current post-pile technology, such piles cannot be pressed into the soil, which will affect the reconstruction and expansion of existing buildings. function, which limits the application of the reconstruction and expansion of existing buildings
