Problems solved by technology

[0011] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a new type of chemical grouting system for high-speed railway base pipe sheds to solve the problem that the existing grouting machine does not use screw grouting and cannot effectively control the grouting pressure. To make it possible to grout under constant pressure, the material flow is not stable enough to ensure the smooth progress of grouting work

Abstract

The invention discloses a novel high-speed rail subgrade pipe-roof-type chemical grouting system. The system structurally includes a grouting machine body, a grouting feeding groove, a screw-type grouting pressurizing device, a controller, an electric cabinet, a fixing base, a discharging hopper, trundles, a grouting high-pressure valve rod, a self-propelled grouting gun head, a material mixing groove, a quantitative grouting barrel, a high pressure gauge and a rack; the grouting feeding groove is formed in the top end of the grouting machine body, the grouting machine body is parallel to thegrouting feeding groove, the quantitative grouting barrel is arranged at the side end of the grouting machine body, and the screw-type grouting pressurizing device is installed in the grouting machinebody; the rack is welded to the four corners of the grouting machine body, the grouting machine body is connected with the fixing base through the rack, the electric cabinet is arranged on the fixingbase, and the controller is arranged above the electric cabinet. Through arrangement of the screw-type grouting pressurizing device, under the cooperation of a pressurizing barrel and a pressure pump, the grouting pressure is effectively controlled, and grouting can be conducted at constant pressure; the material flow is stable, and it is ensured that the grouting work can be completed successfully.

Description

technical field [0001] The invention is a novel base pipe shed type chemical grouting system for high-speed railways, and belongs to the technical field of base pipe shed type chemical grouting for high-speed railways. Background technique [0002] Pipe shed chemical grouting machine process: [0003] (1) The wearing parts of the screw type grouting machine include: flexible stator, rotor, mixing shaft built into the hopper, etc. [0004] (2) The stator of good screw type grouting machine equipment generally adopts nano rubber flexible stator, and the poor quality and low cost are mainly rigid stators. The wear resistance of flexible stators is generally 2-4 grades higher than that of rigid stators; [0005] (3) The rotor of a good screw type grouting machine equipment is relatively well-made, and the surface smoothness of the screw is mainly observed, as well as the matching tolerance with the spiral surface of the stator. A good level of interference fit between the roto...
