Abstract

The invention relates to a track space curved surface concrete flatness control method. The method comprises the following steps of arranging a leveling pipe along a track surface, and fixing the leveling pipe to a reinforcing mesh; spraying concrete on the track surface, and leveling a concrete surface through using a scraper after concrete spraying is completed; and using a trowel to smooth theentire concrete surface, and taking out the leveling pipe before concrete is initially set, and using the same grade of concrete to spray for leveling. In the invention, the flatness of the cambered concrete can be controlled, and the flatness of the curved track whose space shape can be continuously changed can be effectively controlled too.

Description

technical field [0001] The invention relates to the technical field of track construction, in particular to a method for controlling the flatness of concrete on a track space surface. Background technique [0002] Both bobsleigh and sled events are highly ornamental snow sports. The bobsleigh and sled track, as the competition slides for the snowmobile and sled events of the Winter Olympics, is a slide with high quality requirements. [0003] The bobsleigh and sled race track is the snowmobile and sled race track of the Winter Olympics. In order to meet the safety and competitiveness of sports, the smoothness of the slideway surface is highly required, and the flatness error should be controlled within 3mm. The environment, temperature, construction zone and other conditions of slideway construction are all different, and the working environment and working hours of surface modification are also different, but sliding surfaces with different curvatures, shapes, sizes and hei...
