Embodiment Construction

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments, and the mode of the present invention includes but not limited to the following embodiments.

[0022] Such as figure 1 and 2 As shown, a high-precision mirrorless stakeout process for a wind tunnel body provided by the present invention uses the BIM model correction method or the angle and distance double correction method to carry out high-precision mirrorless stakeout for the wind tunnel body. The invention has wonderful conception, scientific and reasonable design, and is convenient to use. It can meet the high-precision non-prism stakeout requirements of the wind tunnel body, overcome the problem that the traditional total station measurement mode cannot meet the stakeout accuracy requirements, and at the same time overcome the inability of the traditional total station prism stakeout. The defects that work on the vertical plane can be applied in a var...

Abstract

The invention discloses a high-precision non-prism lofting process for a wind tunnel body, thereby solving a problem that the traditional total station measurement mode can not meet the lofting precision requirement in the prior art. On the basis of a BIM model correction method or an angle and distance double correction method, high-precision non-prism lofting is performed on the wind tunnel body. The lofting process based on the wonderful concept and scientific and reasonable design is used conveniently; the high-precision non-prism lofting requirement is met; and a problem that traditionaltotal station measurement mode can not meet the lofting precision requirement is solved. Meanwhile, a defect that the traditional total station prism lofting can not work on a vertical plane is overcome. The disclosed process be applied in various complicated cross sections not only can be applied in the wind tunnel building widely but also has the great promotion and application value in other structural buildings.

Description

technical field [0001] The invention relates to the field of building construction measurement, in particular to a high-precision mirrorless lofting process for a wind tunnel body. Background technique [0002] Simply put, a wind tunnel is a device that generates controllable airflow. The ultimate goal of construction is to obtain uniform, controllable, and high-quality test airflow in the wind tunnel test section. The project of the present invention belongs to the return type low-speed wind tunnel, which has a continuous air circuit, and the air flow circulates in the tunnel body. The size of the central axis is 150.86m×45.65m. The design requires that the tunnel body circuit be within the range of 390m in length The axis deviation is not more than 10mm (tolerance accumulation is not allowed), and the step difference is not more than 3mm (not more than 1mm along the airflow direction). The wind tunnel is a frame-beam structure with octagonal, quadrilateral and circular cr...
