Embodiment Construction
[0026] The present invention will be specifically described below in conjunction with the accompanying drawings and embodiments.
[0027] figure 1 Shown is the structural representation of the present invention.
[0028] The present invention comprises a curved ruler main ruler 1, a support 2 and an adjustable support rod 3.
[0029] 1 radian of the main ruler of the curved ruler is equal to the design radian of the pavement surface layer.
[0030] The main ruler 1 of the curved ruler is made of 12mm thick high-quality bamboo plywood or other solid plates, and the joints of the two plates are ribbed, and the width of the main ruler is 50mm.
[0031] The curvature of each section of the circular curve section of the road surface is the same, so the main ruler 1 of the curved ruler is made with the same radian, and the road surface gradually becomes steeper in the gentle curve section, so the main ruler 1 of the curved ruler is made according to the design of each section, and...

The invention discloses a curve control device and method of a double-curved concrete pavement. The curve control device comprises a main scale of a bevel gauge, a bracket and an adjustable supporting rod, wherein the radian of the main scale of the bevel gauge is the same as the design radian of a pavement surface; the bottom end of the adjustable supporting rod is pre-embedded inside concrete, and the upper end of the adjustable supporting rod is connected with the bracket in a welding manner; a concave clamping groove is arranged on the bracket; the main scale of the bevel gauge can be conveniently inserted into the clamping groove; the adjustable supporting rod consists of two round steel sections; a thread is arranged at the middle connection part of the two round steel sections; the two round steel sections are connected through a threaded sleeve; and the height of the adjustable supporting rod can be adjusted by rotating the threaded sleeve. According to the curve control device disclosed by the invention, the curve construction precision can be effectively controlled by replacing a template, so that with the adoption of the pre-embedded bevel gauge, the curve precision of the pavement surface is improved, the quantity of construction gaps is reduced, and the use amount of the template is reduced; and furthermore, the width of a primary pouring concrete board is improved, and the quantity of the construction gaps is greatly reduced.
Description
technical field [0001] The invention relates to a curvature control tool and method in hyperboloid concrete pavement construction. Background technique [0002] The test track is widely used in the tire and automobile industries, and provides a scientific experimental place for testing the performance of tires and automobiles. The curved section of the high-speed ring road is a very critical part of the test track. The curved section of the high-speed ring road of the test track is generally an asphalt pavement, which needs to be completed with a patented curved asphalt paver, and the entry fee and use fee of the machine are extremely high. In order to save the high mechanical cost of imported asphalt paver, concrete pavement is used for the curved section of high-speed ring road of most test tracks in China, but at the same time, there are also common problems such as difficult construction, low construction efficiency, difficult control of construction accuracy, and large ...
