Problems solved by technology

However, when paving with a bridge-type paver with a full-section paving, the steel wire rope is used as the signal reception of the paver for paving, which does not match the signal received by the bridge-type paver, and there...

Embodiment Construction

[0057] In order to further illustrate the features of the present invention, please refer to the following detailed description and accompanying drawings of the present invention. The accompanying drawings are for reference and description only, and are not intended to limit the protection scope of the present invention.

[0058] This embodiment solves the problem of repeated lofting in the traditional full-section paving technology by providing a lofting construction method for paving curved surfaces of high-speed ring roads.

[0059]In order to solve the above-mentioned problems, the general idea of ​​the scheme of this embodiment is: install the high-rail guide beam and the low-rail guide beam necessary for erecting bridge-type paving on the upper and lower parts of the curved surface of the high-speed ring road respectively, and the upper part refers to It is the outer side of Diding Road, and the lower part refers to the inner side of the parking lane. The low rail guide ...

Abstract

The invention discloses a construction setting out method for high speed rotary road curved surface spreading, and belongs to the technical field of building construction. The method comprises the steps of using GPS to set out the positions of reference points on the inner side of a high speed rotary road curved surface, arranging control piles according to the positions of the reference points, and measuring the elevations and plane positions of the control piles; performing low track point setting out, arranging low track support piles at low track points, and erecting low track guide beamson the low track support piles; performing high track point setting out, arranging high track support at high track points, erecting high track guide beams on the high track support piles, and using abridge spreading machine to walk on the high track guide beams and low track guide beams for spreading work to meet the planes and elevations required for the bridge spreading machine to control spreading. When the method is used for curved surface spreading, it is not necessary to repeat the setting out, and the spreading precision is high.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a lofting construction method for paving curved surfaces of high-speed ring roads. Background technique [0002] In consideration of the safety and comfort of the test vehicles, the proving ground has strict requirements on the flatness of the surface of the high-speed ring road during the construction process. The high-speed ring road is the most important in the use of the entire test track. When the vehicle is driving on the curve section of the high-speed ring road, the speed is extremely fast, and at the same time it is accompanied by the effect of centripetal force. This feature requires the high-speed ring road itself to have a high Bearing capacity, stability and flatness. [0003] In the proving ground project, there are two paving technologies for the high-speed ring road on the asphalt pavement, one is segmental paving, and the other is full-section pavi...
