Concrete construction method for engineering

Abstract

The invention discloses a concrete construction method for engineering. The concrete construction method comprises primary stirring, transportation and secondary stirring; in the primary stirring process, part or all of raw materials needed to prepare concrete are mixed with water in a stirring device to obtain a low-water-content mixture with a water content of 3-8%; the low-water-content mixtureis transported to a construction site by a multi-material supply car; in the secondary stirring process, the multi-material supply car is in butt joint with a self-driven stirring train in the construction site; the low-water-content mixture is conveyed into a stirrer of the self-driven stirring train; proportional adding of needed powder or liquid raw materials is realized through control by a powder loading device and a liquid loading device on the self-driven stirring train; then, the stirrer is used for stirring; and after secondary stirring, the concrete is conveyed into a vehicle and equipment in butt joint with the self-driven stirring train by a discharge device, or is unloaded on the ground by the discharge device for use. The method can prevent the influence on the engineering quality by the quality change of the mixture in long-time transportation process.

Description

technical field [0001] The invention belongs to the field of engineering technology, and in particular relates to a construction method of engineering concrete, which transports the mixed material with low water content after the initial mixing in the commercial concrete station and performs secondary mixing on the construction site to obtain the engineering mixed material used for construction. material. Background technique [0002] During the construction process, the concrete used is generally mixed at the commercial concrete station. At this time, the water content in the concrete is relatively high. Therefore, after the mixing is completed, it must be transported by tank trucks. For a long time, this will cause changes in the quality of concrete and affect the quality of engineering construction. Contents of the invention [0003] The purpose of the present invention is to provide a construction method for engineering mixtures. The raw materials to be mixed are firs...
