Embodiment Construction

[0029] The technical solutions of the present invention will be further specifically described below through specific examples, but the present invention is not limited to the examples.

[0030] A method for stakeout of road surface side piles according to the present invention, the stakeout method comprises stakeout of side piles of road surface structure layer in straight section, and stakeout of side piles of road surface structure layer in curved section;

[0031] 1) Stakeout of side piles on the pavement structure layer of the straight line section; the stakeout of side piles adopts the intersecting fixed point of the steel ruler of adjacent middle piles, calculates the intersection distance in advance and then goes to the site to stake out, the longitudinal slope is large and the transverse superelevation is large according to the slope calculation Slope distance; besides the fixed distance between the corresponding middle piles, the distance between the adjacent middle p...

Abstract

The invention discloses a method for setting out side piles on the road surface. The setting out method includes setting out the side piles of the road surface structure layer in the straight line section, setting out the side piles in the road surface structure layer in the curved section; setting out the side piles in the road surface structure layer in the straight section; The middle pile steel ruler measures the distance from the intersection to the fixed point, calculates the intersection distance in advance, and then goes to the site to stake out. If the longitudinal slope is large and the transverse superelevation is large, the slope surface distance is calculated according to the slope; besides the fixed distance between the corresponding middle piles, the stakeout of the side piles is adjacent to each other. The distance from the middle pile to the side pile needs to be calculated. For the straight line segment and the circular curve segment, as long as the distance between the piles is equal, the distance from the adjacent middle pile to the side pile is also the same. The invention has the advantages of simple and fast setting out of road surface side piles, no accumulation error and high precision.

Description

technical field [0001] The invention relates to a building construction method, more specifically, relates to a road surface side pile lofting method for the road surface structure layer and the surface layer side pile lofting after the road middle pile lofting is completed. Background technique [0002] Regardless of the construction of the subgrade and pavement, the stakeout of the centerline and sideline of the road is essential, especially the construction of the pavement structure layer and surface layer, sometimes requiring 10m stakeout mid-side piles. In the past, after setting out the middle pile, the steel ruler was used to measure the position of the side pile directly from the middle pile, and the vertical direction of the straight line or the normal direction of the curve was manually estimated. The manual estimation was not accurate. If the longitudinal slope is large, the design elevation of the side pile deviated from the normal direction Differences will resu...
