A method for reducing bending damage of pipe piles in soft soil

Abstract

The present application relates to the field of construction engineering, in particular to a method for reducing the bending damage of pipe piles in soft soil, which includes the following steps: step 1: survey and detection of the soil layer on the construction site; step 2: set the first layer of reinforcement at the position of the design elevation Step3: Set the second reinforcement layer at the design elevation, and the second reinforcement layer is located above the first reinforcement layer; step4: Drive at least two pipe piles into the soil layer, and the pipe piles pass through the second reinforcement layer in turn layer and the first reinforcement layer; step5: test the bearing capacity of the pipe pile; step6: acceptance. In the present application, a first layer of reinforcement layer and a second layer of reinforcement layer are set in the soil layer in advance, and the two reinforcement layers form a restraint body for the pipe pile at the set elevation, which can support and strengthen the pipe pile, thereby reducing the amount of soil The bending damage of the pipe pile by the layer pressure can maximize the bearing capacity of the pipe pile in the soft soil, and at least two pipe piles are arranged in the two reinforcement layers, which can improve the overall bearing capacity of the pipe pile.

Description

technical field [0001] The present application relates to the field of construction engineering, in particular to a method for reducing bending damage of pipe piles in soft soil. Background technique [0002] Pipe piles are the most common types of piles used in house piling at present. Due to factory production and hollow pipes, they are environmentally friendly piles with reliable quality, material saving and energy saving. [0003] However, because the pipe is hollow, its lateral stiffness is relatively weak, and it is easy to cause buckling damage in deep soft mud, resulting in weaker bearing pressure of the pipe pile in the lateral direction. [0004] In view of the above-mentioned related art, the inventor believes that there is a defect that the lateral bearing capacity of a single pipe pile is poor. SUMMARY OF THE INVENTION [0005] In order to improve the lateral bearing capacity of the pipe pile, the present application provides a method for reducing the bending...
