Embodiment Construction
[0049] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0050] It should be noted that when an element is referred to as being “fixed” or “disposed on” another element, it may be directly on the other element or it may be indirectly fixed or disposed on the other element through a third component. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or it can be indirectly connected to the other element through a third element.
[0051] It is to be understood that the terms "length", "width", "top", "bottom", "front", "rear", "left", "right", "vertical", "horizontal", "top" , "bottom"...

The invention relates to the technical field of construction detection, and particularly provides a deviation detection method. The method comprises the following steps: preparing a detector, transversely placing a detection rack on the upper port of a protection cylinder, connecting a support rack with the detection rack, clamping the supporting rack at the upper port of the protection cylinder,and adjusting the support rack to make the detection rack in a horizontal state relative to the horizontal plane; arranging a driving mechanism on the detection rack, connecting an operating mechanismand a reflecting member with the driving mechanism, and adjusting the horizontal position of the reflecting member in the horizontal state by the driving mechanism; and cooperating a total station with the reflecting member to determine the horizontal center of the protection cylinder, and arranging the operating mechanism at a position, close to the inner cylinder wall of the protection cylinder, in the detection rack in order to make an operator operate the operating mechanism at the circumference side of the protection cylinder. The installation and use process comprising preparation and installation of a test piece, horizontal state adjustment and coarse and fine calibration of the center position is carried out without the operator standing on the protection cylinder, so the safety is ensured; and the detection rack does not deform in the detection process, so the detection accuracy is improved.
Description
technical field [0001] The invention belongs to the technical field of construction detection, and more specifically relates to a deviation detection method. Background technique [0002] With the rapid development of the market economy, the process of urbanization in various places is accelerating. In order to meet the requirements of rapid economic development and the convenience of people's life and travel, a large number of highways, high-speed railways, urban rails and other transportation infrastructures are constantly under construction. In order to meet the needs of bridge engineering construction for clearing roads in mountains and erecting bridges when encountering water, pile foundations are widely used as the most effective way to improve the bearing capacity of foundations. Pile foundations are generally divided into bored piles and prefabricated piles. Among them, the bored pile accounts for about 70% of the pile foundation construction, and the mud arm protect...
