Multi-grading concrete production system for bridge pier pouring and preparation technology thereof

Abstract

The invention provides a multi-grading concrete production system for bridge pier pouring and a preparation technology thereof. A discharging outlet of an aggregate discharging hopper is connected with a second aggregate conveyor belt through a first aggregate conveyor belt; an aggregate vibration discharging machine is arranged under the second aggregate conveyor belt, a discharging outlet of theaggregate vibration discharging machine is connected with a first roller screen through a third aggregate conveyor belt, and a discharging outlet of the first roller screen is provided with a small-particle-size-aggregate conveyor belt, a medium-particle-size-aggregate conveyor belt and a large-particle-size-aggregate conveyor belt; the tail end of a first-grading conveyor belt is connected witha first-grading aggregate tank, the tail end of a second-grading conveyor belt is connected with a second-grading aggregate tank, the tail end of a third-grading conveyor belt is connected with a third-grading aggregate tank, and the tail end of a fourth-grading conveyor belt is connected with a fourth-grading aggregate tank; and a fifth aggregate conveyor belt is connected with a mixing plant, and the top of the stirring building communicates with other raw material compounding systems. The multi-grading concrete production system can be used for production preparation of concrete for bridgepier pouring, thus the optimum effect of the concrete is achieved, and finally, the quality of a poured bridge pier is ensured.

Description

technical field [0001] The invention relates to the field of concrete processing and production equipment, in particular to a multi-graded concrete production system and preparation process for pouring bridge piers. Background technique [0002] For large-scale bridge construction, the bridge pier is the main bearing body of the whole bridge, and its structural strength is related to the quality and life of the whole bridge. Therefore, during the pouring process of the bridge pier, the performance requirements of its concrete are extremely high. On the one hand, it is necessary to ensure that there is a need for coarse aggregate in the concrete raw materials, and the coarse aggregate needs to be multi-graded; Other types of admixtures such as coal ash, water reducer, expansion agent, etc., due to the large amount of concrete poured on bridge piers, there is currently no production system specially used for the above concrete preparation, so we can only redesign the productio...

[0002] For large-scale bridge construction, the bridge pier is the main bearing body of the whole bridge, and its structural strength is related to the quality and life of the whole bridge. Therefore, during the pouring process of the bridge pier, the performance requirements of its concrete are extremely high. On the one hand, it is necessary to ensure that there is a need for coarse aggregate in the concrete raw materials, and the coarse aggregate needs to be multi-graded; Other types of admixtures such as coal ash, water reducer, expansion agent, etc., due to the large amount of concrete poured on bridge piers, there is currently no production system specially used for the above concrete preparation, so we can only redesign the production system suitable for the above concrete preparation production system
