Insert type concrete vibrorammer combining vacuum air exhaust and water suction and principles thereof

Abstract

The invention discloses an insert type concrete vibrorammer combining vacuum air exhaust and water suction and principles thereof, and belongs to the technical field of construction engineering machines. The vibrorammer solves the problems that microbubbles and free water in concrete and bubbles attached to a template are difficult to eliminate through existing insert type vibrorammers by means of vibration waves, the number of bubbles on the surface of the concrete is large, the appearance quality of the concrete is poor, outside air and water invade steel from air holes in the surface of the concrete and rust the steel, and reinforced concrete component concrete protection layers fall off, so that the service life of structures and buildings is shortened, and the effects that set cement and cement paste in the concrete are forced to be more compact and the segregation phenomenon of the concrete in the vibration process is avoided are achieved. The strength of the concrete is improved, the bearing capacity of the structures and the buildings is improved, and the service life of reinforced concrete components is prolonged. An insert type concrete vibrorammer nanoscale micropore shell bar body connects a motor and a vacuum pump through double-pore-channel hoses into a system combining vibration, air exhaust and water suction.

Description

technical field [0001] The present invention relates to concrete pouring components that have been mixed by a concrete mixer, air bubbles and free water must be excluded, and tamping is carried out to make the concrete densely bonded, and eliminate the honeycomb pockmarked surface cracks of the concrete, so as to improve its strength and improve the quality of the concrete. The appearance of the component ensures the quality and service life of the concrete component. Specifically, it relates to a machine tool for mechanized high-efficiency compaction of concrete, which is a plug-in concrete vibrator combined with vacuum pumping and water absorption. Background technique [0002] At present, concrete is an overall dense engineering composite material composed of aggregates combined with cementitious materials. It has been widely used in basic construction fields such as construction engineering, bridge engineering, and traffic engineering. Under normal circumstances, the c...

AI Technical Summary

Problems solved by technology

It solves the problem that the existing plug-in vibrator cannot well remove the air bubbles and free water inside and on the surface of the concrete. The actual construction test shows that every time the air content of concrete is reduced by 1%, its strength will increase by 5-6%. If the free water of concrete is reduced by 1%, the strength of concrete will be increased by 10-15%, which solves the problem that the internal quality and appearance quality of concrete components directly affect the construction requirements.
