Sleeper vibration stirring construction process

Abstract

The invention particularly discloses a sleeper vibration stirring construction process. The sleeper vibration stirring construction process comprises the steps that vibration stirring is conducted on sleeper concrete through a high-frequency vibration platform which can conduct vibration obliquely, and the concrete is poured into a feed trough; and high-frequency vibration is conducted on the sleeper concrete through the high-frequency vibration platform, and an electromagnetic vibration device is controlled to rotate left and right on a rotating fixed frame while high-frequency vibration is conducted. According to the sleeper vibration stirring construction process, all materials in the sleeper concrete can be fully vibrated, the compactness of the sleeper concrete is improved, thus, the bond stress of the sleeper concrete and steel bars is also improved, and the strength of the sleeper concrete is improved.

Description

technical field [0001] The invention relates to the technical field of concrete construction, in particular to a vibration-stirring construction technology for sleepers. Background technique [0002] Sleepers include concrete sleepers and wooden sleepers, which are widely used in my country's transportation infrastructure, and currently the most widely used are concrete sleepers, and prefabricated concrete sleepers are mostly used. [0003] Usually, the production system of concrete sleeper prefabricated parts includes mold table, driving roller, distributing machine and vibrating device. The driving roller is arranged in a straight line on the ground of the workshop, and the mold table is set on the driving roller and moves along the arrangement direction of the driving roller under the drive of the driving roller. , the placing machine is usually erected above the factory building, and the vibrating device is set on the ground; at the pouring station, the placing machine p...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, the amplitude, frequency, vibration time and vibration area of ​​the vibrating table are usually fixed, but the fixed frequency and amplitude are because the water-cement ratio, slump and fluidity of concrete are ever-changing, and the main coarse Aggregate, affected by material, hardness and shape, etc., its own natural frequency that causes its resonance is also ever-changing, which ultimately affects the quality and production efficiency of concrete prefabricated parts, so the vibration compaction effect of existing concrete is often not as good as expected
