Abstract

Tunnel construction survey must be necessary to be very quick so that the results can be known as soon as possible. This aim can be achieved through the intelligent positioning method of tunnel excavation face. In this study, the plane parameters of the tunnel cross-section were transformed into the coordinates of the points on the cross-section to realize the automatic transformation of graphic data. According to the theoretical calculation of the lofting point accuracy, the appropriate measurement control network level and measurement accuracy and the appropriate measurement instruments were selected. The fast and intelligent positioning and setting out of tunnel excavation face was realized base on the technology of data communication between computer and measuring instruments. The intelligent positioning method of tunnel excavation face could greatly reduce the time of measurement and positioning, speed up the project progress, reduce the project risk, shorten the construction period and reduce the project cost.

Abstract

The speed of test vehicles on the high-speed car track of the automobile test field is very high. Reducing the construction error of asphalt pavement is very important to ensure the safety of the test vehicle. In order to realize the paving of asphalt concrete pavement with super-large lateral inclination in the curve section of the high-speed car track in the automobile test field, a special paving control device and control method for the construction on the curve section with super-large lateral inclination were developed. Use the direction of the hanging hammer under the GPS device of paver to adjust the position of GPS device in real time, so that the geometric centre line of GPS device is always perpendicular to the horizontal plane. The reference control line is preset in the paver operation control device, and the lateral displacement deviation of the paver is adjusted to synchronize the data of the paver control device with the travel route. The precise control of the paver’s forward route is realized, the construction precision of the super-large inclined asphalt pavement on the high-speed car track of the automobile test field is achieved, and the construction efficiency is greatly improved. It has important reference value for similar projects such as automobile testing field and racing track.
