Description

Technical Field

[0001] The utility model relates to a highway roadbed sand blowing backfill construction device, belonging to the technical field of highway roadbed construction. Background Art

[0002] With the development of social economy, in order to facilitate passage and transportation, more and more roads are being laid and the scope is becoming wider and wider. In order to reduce costs and working hours, existing roads can be renovated and constructed on existing routes when they are laid. There are more and more reinforced concrete culverts passing under the road surface. In order to reduce the impact of construction on existing routes, these culverts are generally constructed by top-down. At present, most culverts are protective culverts, and municipal pipelines are generally required to be inserted into their interior. In addition, the gap between the municipal pipeline and the protective culvert needs to be backfilled with sand and gravel to protect it. In this case, a sand blowing backfill construction device is required.

[0003] After searching, it was found that the highway roadbed sand blowing backfill construction device described in the authorization announcement number CN219793492U has the following beneficial effects: 1. The highway roadbed sand blowing backfill construction device, by setting a beating structure, after the sand and gravel fall onto the filter frame through the feed port, the first forward and reverse motor is started to drive the drive shaft to rotate, so that the two sides of the connecting plate can move up and down, so that the beating plate can beat the filter frame as the connecting plate moves, and the sand and gravel stuck in the through holes opened in the filter frame can be beaten down, preventing the sand and gravel from being stuck in the through holes and causing the through holes to be blocked, which may lead to poor screening effect, so as to facilitate subsequent use. At the same time, it also prevents the problem of damage to the filter frame. In addition, the aperture of the through hole is limited, which also reduces the difficulty of removing the sand and gravel stuck in the through hole. The operation is simple and convenient, which improves the use effect of the backfill construction device. 2. The highway roadbed sand blowing backfill construction device is provided with an adjustment structure. When in use, the second forward and reverse motor is turned on, and the second forward and reverse motor drives the screw to rotate, so that the screw block moves in the slide groove. The discharge position of the discharge pipe can be adjusted according to the actual backfilling situation to reach different backfilling sites, thereby enhancing the applicability and having no limitations. In addition, there is no need to connect other discharge pipes, which is easy to use. In addition, when storing or transporting, it can be restored to its original position according to the above operation, thereby preventing the discharge pipe from protruding too long and occupying a large space.

[0004] However, during use, it does not have the function of sucking away the dust generated by backfilling. The dust generated during backfilling not only pollutes the environment, but also causes great harm to the physical and mental health of the workers. Therefore, a highway roadbed sand blowing backfill construction device is needed to facilitate people's use. Utility Model Content
