Abstract
Description
Technical Field
[0001] This utility model relates to the field of pile foundation technology, and in particular to an anti-deviation device for pile foundation construction. Background Technology
[0002] A pile foundation is a deep foundation consisting of piles and pile caps connecting the pile tops, or a single-pile foundation connecting a column to the pile foundation. Its core function is to transfer the building load to deeper, more resilient soil or rock layers underground, addressing problems such as weak shallow foundations, excessive settlement, or insufficient seismic stability. Based on the installation location, pile foundations can be divided into low-pile-cap pile foundations and high-pile-cap pile foundations, with the former being more commonly used in construction. Pile foundations are mainly classified according to their load-bearing principle into friction piles and end-bearing piles; and according to their construction method into precast piles and cast-in-place piles.
[0003] One of the announcements, CN218521770U, describes a pile foundation construction anti-deviation correction device. This device installs a positioning bottom ring at a designated position via positioning blocks and pins. The bottom and top positioning rings prevent pile deviation. When the pile deviates, the control switch of an electric cylinder is activated. The electric cylinder pushes an arc-shaped push plate towards the center, which in turn pushes the pile towards the center, correcting the pile. However, this technical solution uses a motor-driven air pump as the air source, and the correction is achieved through a telescopic cylinder containing gas. Since gas is easily compressed, the resulting corrective thrust is relatively small. Furthermore, the electric cylinder is supported by a vertical plate, which provides limited support, making the device itself prone to tilting. Therefore, its anti-deviation and correction capabilities are poor, resulting in low practicality. Utility Model Content

The height limiting rings 5 are square rings with rounded corners. The inner diameter of the four height guide plates 4 is equal to the inner diameter of the guide tube 14. The guide tube 14 is installed in the guide through hole of the anti-deviation base plate 1. Four anti-slip nails are installed on the lower wall of the anti-deviation base plate 1. The outer edge of the anti-deviation base plate 1 is square with rounded corners.
[0026] As a preferred embodiment, the four guide rail structures further include: a guide base plate 6, a guide slide rail 7, and a slide rail slider 8; the guide base plate 6 is installed on the side wall of the anti-deviation base plate 1, the guide slide rail 7 is installed on the upper wall of the guide base plate 6, the upper wall of the guide base plate 6 is provided with several positioning holes, the slide rail slider 8 is movably installed on the outside of the guide slide rail 7, and the slide rail slider 8 is fixed by a pin passing through the positioning hole of the guide base plate 6.

Next, the operator places the anti-deviation base plate 1 above the hole, while the guide tube 14 is attached to the inner wall of the hole. Because anti-slip nails are installed at the bottom of the anti-deviation base plate 1, its position is secured.

The operator fixes the slider 8 and the guide base plate 6 relatively with the positioning pin, and the adjustment is completed.
[0031] The operator guides the pile into the hole through four height guide plates 4 and guide tubes 14, thus ensuring that the pile is installed into the pile foundation hole in a vertical manner as specified.
