Intelligent vacuum circulating propulsion grouting system

Abstract

The invention relates to an intelligent vacuum circulating propulsion grouting system. A slurry outlet of a high-pressure agitation circulating system is lower than the bottom of a low-speed mixing barrel system; the installation position of a propulsion type high-speed mixing circulation system is lower than that of the low-speed mixing barrel system, and mud is conveyed out by an impeller pump in the propulsion type high-speed mixing circulation system; a rotating shaft of a disc turbine is vertically supported upward on the upper side and the lower side of an impeller pump casing, and the position, higher than the disc turbine, of the rotating shaft is fixedly provided with a propulsion type high-speed mixer; and a plurality of spoilers distributed radially are fixedly arranged on a conical bottom inside the impeller pump casing. The intelligent vacuum circulating propulsion type grouting system has the advantages that the installation height of the propulsion high-speed mixing circulation system is lowered, the high-speed rotation is stable, the measurement precision of a weighing sensor is high, and the maintenance and cleaning is convenient; the automatic pulping is achieved,the quality of slurry is ensured, the grouting output and the dwell pressure are stable, the amount of grouting can be detected to ensure full slurry in tunnel and data of the grouting process is automatically recorded; and the degree of automation is high, and the quality of projects is improved.

Description

technical field [0001] The invention relates to the technical field of prestressed stirring, in particular to an intelligent vacuum circulation propulsion grouting system. Background technique [0002] In the traditional vacuum circulation grouting system, the position of the high-speed mixing tank must be higher than that of the low-speed mixing tank, so as to ensure that the mud prepared by the high-speed mixing tank can flow into the low-speed mixing tank by the weight of the mud. The high-speed barrel is stirred at a high position. Under high-speed rotation, the shaking force is large, causing instability, making the measurement accuracy of the load cell poor, and maintenance and cleaning are inconvenient; Guaranteed, it is inconvenient to observe, the stroke of the feeding machine is also longer, the difficulty of manufacturing is increased, the degree of deformation is difficult to control, the life and durability are reduced, and the cost is also increased.
