Modified cement concrete mixing system for concrete mixing station

Abstract

The invention discloses a modified cement concrete mixing system for a concrete mixing station. A modifier pool A and a modifier pool B are respectively communicated with a modifier scale A and a modifier scale B through hydraulic pumps, wherein the modifier scale B is communicated with the modifier scale A through the hydraulic pump and a premixing device; the premixing device is communicated with a mixed emulsion scale through a pipeline; the mixed emulsion scale and a water reducer scale are communicated with a water scale; the water scale is arranged above a mixing pot; a modifier A and a modifier B are respectively conveyed to respective weighing systems through the hydraulic pumps, and are weighed and pumped into the premixing device to mix; metered water reducer can be added when water is weighed in the water scale; mixed liquid of the modifier A and the modifier B, water and the water reducer flow into the stirring pot from the water scale; the modified cement concrete is mixed; and the water scale is transformed, so that a secondary feeding procedure with high metering accuracy is realized; and problems of uneven mixing and inaccurate metering of admixtures are prevented.

Description

technical field [0001] The invention relates to a premixing device for a concrete mixing station, in particular to a modified cement concrete mixing system for a concrete mixing station. Background technique [0002] Ordinary cement concrete has the disadvantages of high brittleness, weak impact resistance and fatigue ability, and poor wheel wear and polishing performance. When it is applied to the pavement surface layer, it is prone to damage such as plate fracture and surface structure damage, which limits its use in high In addition, the smell of hot asphalt concrete is very pungent, which is harmful to the health of construction workers, and the construction environment is harsh. Ordinary cement is used for insufficient bonding between the asphalt concrete bridge deck pavement and the reinforced concrete bridge deck. It is prone to shear failure; in terms of raw materials, my country lacks high-quality asphalt resources, but cement resources are abundant. [0003] Therefo...
