The embodiment of the invention provides an intelligent non-pulse grouting pump for an indoor model test and a using method of the intelligent non-pulse grouting pump. The grouting pump comprises a pump body, a piston rod, a pumping system, a slurry storage tank, a slurry conveying pipe, a slurry discharging pipe, a hydraulic system and a PLC control system. The using method comprises the steps that the PLC control system sets the grouting pressure or the grouting speed, transmits signals to the hydraulic system and adjusts and propels an oil cylinder to control the reciprocating motion of thepiston; when the piston moves upwards, a steel ball in the upper part seals a rod cavity, the size is reduced, and grouting is realized; and when the piston moves downwards, a steel ball in the lowerpart seals a rodless cavity, the size is reduced, and grouting is realized. According to the intelligent non-pulse grouting pump for the indoor model test and the using method of the intelligent non-pulse grouting pump, high-flow, high-pressure and high-precision grouting requirements can be met, quantitative control and monitoring can be effectively realized on the grouting amount and the grouting speed, and meanwhile, during the reciprocating motion, the same grouting amount is achieved at the same grouting speed, so that the guarantee is provided for achieving accurate control; and the test data are easy to collect, so that the grouting pump can be widely applied to the indoor model test.
