Problems solved by technology
[0004] In the existing technology, the positioning of the circular boss still stays on the method of setting out the total station. First, the contour line of the circular boss is manually drawn on the ground with a compass to locate the plane position, and then the leveling is controlled repeatedly. Top surface elevation, this positioning method is inefficient, and often requires a large number of surveyors and instruments to ensure the construction progress, and the positioning accuracy is low, often causing deviations in the plane position of the circular boss and the top surface elevation control, affecting the construction quality

Embodiment Construction
[0023] see figure 1 , figure 2 and image 3 , in the present embodiment, a circular mold 1 equal to the diameter of the circular boss is set, and a crossbeam 2 is arranged radially on the top surface of the circular mold 1, and on the crossbeam 2, it is positioned at the circular mold A prism connector 2a for installing the prism 2b is arranged at the center of the ring of 1; four radial lugs 1a are distributed in a cross on the periphery of the ring-shaped mold 1, and each radial lug 1a is respectively set There are vertical screw rods 4 that can be adjusted in height and have a height scale scale 5, and each vertical screw rod 4 constitutes the elevation control part 3 of the annular mold 1.
[0024] see Figure 4 , the elevation control part 3 is a height-adjustable screw assembly with a height scale scale 5, the thread cooperation of the longitudinal screw 4 and the radial lug 1a makes it possible to adjust the height of the longitudinal screw 4, and then adjust the lo...

The invention discloses a method for positioning round bosses on a motordrome pavement. The method is characterized by comprising the following steps of: arranging an annular die which shares the same diameter with the round boss, arranging a crossbeam on the top surface of the annular die along the radial direction, mounting a prism connecting piece for installing a prism at the central position of annular die on the crossbeam, distributing four radial lugs in a crossed pattern on the periphery of the annular die, respectively mounting a vertical screw which can undergo height adjustment and has height scale in each radial lug, and forming an elevation control member of the annular die by each vertical screw. The positioning device provided by the invention can be utilized to realize rapid and accurate positioning of round bosses on the motordrome pavement.
Description
[0001] This application is a divisional application with the filing date: July 20, 2011; the application number: 2011102041360; the title of the invention is: the positioning device for the circular boss on the road surface of the proving ground and its positioning method. technical field [0002] The invention relates to an auxiliary positioning device and a positioning method used in the road construction of a proving ground. Background technique [0003] The proving ground is a place specially designed and constructed for testing the comprehensive performance of automobiles. It can carry out professional testing of various vehicles, as well as training of drivers of various models, as well as display and test drive activities. The pavement with large and small circular protrusions is located in the durability test section of the proving ground. The circular protrusions are arranged according to the set positions on the road surface, including large and small round protrusi...
