Dam-fill material slope paving device and method

Abstract

The invention discloses a dam-fill material slope paving device and method. The structure of the device includes that two I-shaped steel tracks parallel to each other are fixed to the high position and the lower position of a dam body; the two ends of a rack are each provided with a driving wheel; one driving wheel is arranged on the I-shaped steel track at the high position, and other driving wheel is arranged on the I-shaped steel track at the lower position; a traction chain moving cyclically is arranged on the lower portion of the rack; a plurality of scraper blades are fixed to the outerside of the traction chain at certain intervals; the traction chain is driven by a driving chain wheel fixed to the high position of the rack; and a material collecting hopper used for building materials to flow out is further fixed to the high position of the rack. After the dam-fill material slope paving device and method are adopted, compared with a traditional construction measure, the construction efficiency is remarkably improved, the construction time is remarkably shortened, and experience can be provided for similar engineering.

Description

technical field [0001] The invention relates to the construction technology of fine aggregate slope paving for earth-rock dams (face dams) and pumped storage power stations (reservoir basins), in particular to a slope paving device and method for dam body materials. Background technique [0002] In the field of hydropower engineering, face dams and pumped storage power plants are more important dam types in today's society. However, as the main filling dam material, the cushion material mainly plays the role of anti-filtration and coordinating deformation. During the construction process, it must be ensured that the filling thickness meets the requirements so that it can play its due role and function. [0003] Cushion material is usually arranged on the side facing the water, the slope angle is mostly 1:1.5~1:2, and the filler width is about 1.0m. Due to the limitations of the filler, it is difficult to control the thickness of the filler and the construction during the co...

AI Technical Summary

Problems solved by technology

This method can basically realize the paving of cushion materials, but due to the influence of paving equipment and the difference in the level of operators, the paving thickness is prone to inconsistency, resulting in weak parts

Backhoe paving has reserved a backhoe operation channel, and it is difficult to fill in the later stage, and the quality of rolling construction for this part is not easy to control

At the same time, the slope of the cushion material is long, and the backhoe cannot lay the material at one time. When the upper layer is laid, the filler is prone to slipping, which affects the quality of the lower part of the formed construction part to a certain extent.
