Pavement construction lofting method for high-speed loop in skid pad

Abstract

The invention discloses a pavement construction lofting method for a high-speed loop in a skid pad. The method is characterized by comprising the following steps of: arranging basic control network points on the inner side of a loop curve section subgrade to establish a basic control network; and fixing the height of an instrument in the lofting process, and performing planar and height lofting simultaneously, wherein the height of an intelligent total station instrument and the height of a reflecting prism are not required to be measured during planar lofting, a balance level is not required additionally during height lofting, automatic locking, and automatic aiming and three-dimensional coordinate synchronous lofting are realized by using a TCRP1201 intelligent total station instrument, so that the working efficiency of construction lofting for the high-speed loop in the skid pad can be greatly increased.

Description

technical field [0001] The invention relates to a method for setting out templates during construction, more specifically to a method for setting out templates for curved surface construction of high-speed ring roads in proving grounds. Background technique [0002] In the test track project, the construction accuracy of the high-speed ring road is high, and because the high-speed ring road is a vertical curved surface, the concrete pouring is required to be carried out in sections from bottom to top, the construction process is complicated, and construction lofting is particularly important. At present, the construction stakeout methods for the high-speed ring road of the test track in my country are mainly: adopt the common construction stakeout method in highway construction, use the ordinary total station to stake out the plane position, and the level to stake out the elevation position. The stakeout process is more complicated and the precision control is difficult. Work ...
