Embodiment 1

[0026] Such as figure 1 As shown, the present embodiment provides a track spraying structure for spraying concrete on the track 10, including the bottom 11 of the track 10, the lower cornice 12 connected to one end of the bottom 11, and the other end of the bottom 11. A high wall 13 connected at one end and an upper cornice 14 connected with the high wall 13, wherein the bottom 11 of the race track 10 is laid with a first template 111, a first steel bar on the first template 111 and a The first leveling pipe 112 on the first steel bar, the lower eaves 12 of the track 10 are laid with a second formwork 121, a second steel bar on the second formwork 121 and a second steel bar on the second steel bar. The second leveling pipe 122 of the track 10, the high wall 13 of the race track 10 is sequentially laid with a non-dismantling mesh 131, a third steel bar on the non-dismantling mesh 131, and a third leveling on the third steel bar. pipe 132, the upper cornice 14 of the track 10 i...

Embodiment 2

[0030] Such as figure 1 with figure 2 As shown, this embodiment provides a race track injection molding method, using the race track injection structure described in Embodiment 1 to spray concrete on the race track, which includes the following steps: Step S1: by the first leveling pipe 112 One side passes through the first leveling pipe 112 to spray concrete on the bottom 11 of the track 10, so that the concrete covers the first template 111 and is flush with the surface where the first steel bar is located; Step S2: The lower eaves 12, the high wall 13 and the upper eaves 14 of the track 10 are sprayed with concrete; step S3: continue to spray concrete on the bottom 11 and from the side of the first leveling pipe 112.

[0031] In the racetrack injection molding method described in this embodiment, in step S1, one side of the first leveling pipe 112 passes through the first leveling pipe 112 to spray concrete on the bottom 11 of the racetrack 10, so that Concrete covers th...

Abstract

The invention relates to a racing track spraying structure and a racing track spraying molding method. The structure comprises a racing track bottom, a lower cornice connected with one end of the bottom, a high wall connected with the other end of the bottom, and an upper cornice connected with the high wall. Segment spraying along the length direction of a racing track comprises the following steps: spraying of concrete to the racing track bottom until the concrete is in flush with the reinforcement surface of the bottom; spraying of the lower cornice of the racing track; spraying of the highwall of the racing track; spraying of the upper cornice of the racing track; and spraying of the surface layer of the bottom. The structure and the method have the advantages of facilitation of the improvement of the compactness of sprayed concrete, control of the flatness of the concrete sprayed on the racing track, facilitation of ensuring of the arc of the concrete sprayed on the racing track,facilitation of the processing of a sprayed concrete rebound material, and improvement of the spraying efficiency of the sprayed concrete.

Description

technical field [0001] The invention relates to the technical field of track construction, in particular to a track injection structure and a track injection molding method. Background technique [0002] The 24th Winter Olympic Games will be held in Beijing in 2022. Beijing will host all ice events, while Yanqing and Zhangjiakou will host all snow events. In order to ensure the smooth progress of the Winter Olympics, the relevant competition venues are also under construction. [0003] 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. Since this track is the first in China and the third in Asia, it is the most difficult and complex facility to design in the Beijing Winter Olympics. The track currently under construction has the following characteristics: the main track is 1,975 meters long, and its mai...
