Method for arranging pile foundations in complex soft soil foundation

Abstract

The invention relates to the field of constructional engineering and particularly relates to a method for arranging pile foundations in a complex soft soil foundation. The invention adopts the following specific technical scheme that the method for arranging the pile foundations in the complex soft soil foundation comprises the following steps of: uniformly drawing contour lines on the foundation; arranging pile foundation piling positions on the foundation on which the contour lines are drawn and carrying out trial piling to extract a rock sample in the foundation; measuring distances between the contour lines and an elevation of a region and selecting the depth that each pile foundation is piled into a rock fundamental plane; measuring a perpendicular length of positions between each two adjacent contour lines, which pass through the center point of the position of the pile foundation, and a perpendicular length between each contour line and the center point of the position of the pile foundation; and dividing the value of the perpendicular length between each contour line and the center point of the position of the pile foundation by the value of the perpendicular length of the positions between each two adjacent contour lines, which pass through the center point of the position of the pile foundation, so as to determine the elevation of a pile tip. The invention adopts the technical scheme and provides the method for arranging the pile foundations in the complex soft soil foundation, which can be used for testing the arrangement depth of the pile foundations in the complex soft soil foundation, enable a building not to be settled and enable intensity to be improved.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to a method for setting pile foundations in complex soft soil foundations. Background technique [0002] Constrained by land, more and more substations are built in soft soil foundations in coastal areas. In order to meet the strength requirements and settlement constraints, pile foundations are widely used in the foundation of substation buildings. Therefore, the quality of the pile foundation is directly related to the safe operation of the substation. And for the soft soil foundation where the underlying layer is inclined bedrock, the bearing layer at the pile end of the pile foundation and the depth into the rock directly determine the quality of the pile. [0003] After continuous testing and research and development by technicians in this field, medium and long piles can be used for the foundation of substation buildings in soft soil foundations. For the soft soil fo...

AI Technical Summary

Problems solved by technology

However, for some soft soil foundations with complex geological conditions, such as the soft soil foundation where the underlying layer is inclined bedrock, neither the construction unit nor the supervisor can clearly implement the design plan, which makes it extremely difficult to install substations on complex soft soil foundations At the same time, the strength problem and settlement problem of the substation cannot be dealt with relatively well.
