Embodiment Construction

[0030] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments. Advantages and features of the present invention will be apparent from the following description and claims. It should be noted that the drawings are all in a very simplified form and use inaccurate scales, and are only used to facilitate and clearly assist the purpose of illustrating the embodiments of the present invention.

[0031] The specific implementation process mainly includes the following steps:

[0032] The first step: point selection: it is the control point of the entire construction site, and the location and number of control points are determined by comprehensively considering the later construction needs and site landform conditions; the systematic points have good visibility and the basis of point selection is stable , far away from the excavation area, not easy to damage, does not affect other constructions, and the...

Abstract

The invention provides a stable forced centering disc. The stable forced centering disc comprises a centering disc body arranged at the top of a centering disc frame, an instrument mounting hole is formed in the center of the centering disc body, a limiting base is arranged right under the centering disc body and fixedly connected with the centering disc body through an inverted triangular support, and a limiting hole in the center of the limiting base and the instrument mounting hole are kept to allow a pre-buried frame body to pass through; and the limiting base is fixedly connected with a supporting plane through a triangular support. The stable forced centering disc is better in precision control, stability and visibility, excellent in comprehensive performance and remarkable in systemeffective control effect, and powerful technical and management support is provided for fine management and operation of building construction in measurement related work.

Description

technical field [0001] The invention belongs to a position measurement system, in particular to a building construction measurement control system. Background technique [0002] In the current construction process, the main method is to use traditional control reference points, temporary lead points, test nails, cross marks and other simple methods. In horizontal comparison, the current measurement methods mainly have the following disadvantages: [0003] (1) In the case of large plots and multiple units, the system control is poor; [0004] (2) The accuracy cannot be effectively guaranteed, and the stability is poor; [0005] (3) The selected points are all on the surface and nearby, and the overall permeability is poor; [0006] (4) It is greatly affected by environmental interference, especially in windy weather conditions; [0007] (5) Poor avoidance of accidental errors of personnel and instruments; [0008] (6) The traditional instrument frame is supported, and th...
