Description

Concrete dam construction device based on 3D printing technology

technical field

The utility model belongs to the technical field of large-volume concrete safety construction, and in particular relates to a concrete dam construction device based on 3D printing technology.

Background technique

Concrete paving is a construction machine that paves the mixed cement concrete along the given thickness, width and road type requirements of the subgrade, and then performs operations such as vibrating, leveling and troweling to complete the paving of the concrete pavement. Among them, the concrete paver is generally composed of a distributor, a pre-leveling mechanism, a vibrator (including a vibrating rod and a vibrating beam), a leveling machine, a trowel and other devices. Running on the rail formwork, it can be paved into a driving belt. The rail formwork is not only the driving track of the paver, but also the side formwork for paving the road. The specific construction process is as follows: first, the cement concrete that has been dumped on the roadbed is evenly spread on the roadbed according to a certain thickness by the distributor, and then the pre-leveling structure is paved and the vibrating device is used to vibrate, and then it is troweled. machine smoothing. During the hardening of the concrete, keep the rail formwork undismantled, and then disassemble the rail formwork after hardening, and continue to pave the next section of road surface.

The pre-leveling mechanism on the existing concrete paver is usually a scraper, the scraper itself can rotate, and the scraper spreads the accumulated concrete when the paver moves (mainly pushes the concrete towards the paver moving direction) , so that the height of the concrete paved road is consistent. The disadvantage of this mechanism is that if there is more concrete in the forward direction of the paver, the scraper will encounter greater resistance when it is pushed, which will ultimately affect the paving effect.
