Description

Pile foundation verticality detection device

Technical Field

The utility model relates to a building engineering machinery technical field specifically is a pile foundation straightness detection device that hangs down.

Background

Deep foundations (see the figure) consisting of piles and pile caps (referred to as caps for short) connecting pile tops or single-pile foundations, referred to as pile foundations for short, connecting piles with piles. If the pile body is completely buried in the soil and the bottom surface of the bearing platform is contacted with the soil body, the pile body is called a low bearing platform pile foundation; when the upper part of the pile body is exposed out of the ground and the bottom of the pile cap is positioned above the ground, the pile body is called a high pile cap pile foundation. Building pile foundations are typically low cap pile foundations. In high-rise buildings, pile foundations are widely applied. The method comprises the following main classification: firstly, the foundation can be roughly divided into friction piles and bearing piles according to the stress principle of the foundation. 1. The friction piles utilize the friction force between the ground and the foundation piles to support the structure and can be divided into pressure piles and tension piles, which are generally used for the ground without a hard bearing layer or with a deeper bearing layer. 2. End-bearing piles are those in which foundation piles are seated on bearing layers (bedrock) to bear structures. And secondly, the construction method can be divided into a precast pile and a cast-in-place pile. 1.
