Construction device capable of controlling grain size and grading of rockfill concrete block and grain size ratio of rock
By controlling the particle size and gradation of the rockfill concrete through the transverse guide rail and the rockfill mesh system, the problem of uneven particle size distribution during construction was solved, thereby improving the quality and crack resistance of the concrete rockfill dam.

AI Technical Summary
In existing riprap concrete construction, uneven particle size distribution leads to dam quality problems, and there is a lack of devices for real-time control of riprap particle size distribution and gradation characteristics.
A construction device is used to control the particle size, gradation, and aggregate size ratio of riprap concrete blocks. It utilizes a transverse guide rail, a vertical guide rail, a stone-catching net, and a rope system. By adjusting the gap of the vertical guide rail and the stone-catching net to capture the riprap blocks, the uniformity of particle size and gradation is ensured.
It enables real-time control of rockfill particle size, gradation, and aggregate particle size ratio during construction, preventing rock movement and improving the uniformity and crack resistance of concrete rockfill dams.
