Description
Technical Field
[0001] The present invention relates to the technical field of grouting, and more specifically to a double-liquid grouting machine and a construction method thereof. Background Art
[0002] During the construction and operation of mountain tunnels, subway tunnels, underground projects, etc., there are often situations where grouting repairs or grouting reinforcement and lifting are required. The grouting machine is one of the most important equipment in grouting construction. The grouting machine injects the adjusted slurry into the space that needs to be filled and reinforced to achieve the purpose of filling the pores and stabilizing the soil. At present, two different types of slurries are mixed to form the final grouting slurry in many construction processes. During double slurry grouting, if the grouting amount, grouting pressure, grouting direction, setting time and other grouting parameters of the two slurries are not controlled in time, the grouting during the construction process often cannot be perfectly formed in one time, which affects the quality of the grouting and leads to secondary grouting.
[0003] At the same time, due to the long time of configuration of double liquid grouting, there is a possibility that the two slurries A and B may be stratified and precipitated, resulting in insufficient mixing of the two slurries, making it difficult to achieve the perfect double slurry grouting effect. At present, in the construction of double liquid grouting, a grouting pipe is generally used. The double slurries are mixed at the upper orifice of the grouting pipe and then enter the grouting pipe. Then, under the pressure of the slurry, the temporary plug at the bottom of the grouting pipe is pushed open and enters the soil to solidify, achieving the effect of repairing pores. However, since the double slurry will react chemically in the grouting pipe, it is affected by factors such as the length of the grouting pipe, the size of the grouting pressure, and the chemical reaction rate. The specific coagulation time and coagulation position of the double slurry are difficult to grasp, and the slurry mixing uniformity is not high. After the unmixed slurry is injected into the formation, the grouting effect cannot be achieved. Moreover, the grouting pipe is also prone to blockage.
[0004] At the same time, after the grouting operation is completed, the residual slurry in the pipeline is often not cleaned in time, causing the grouting pipeline to be blocked, affecting the construction efficiency. Summary of the invention

If there is no leakage, inject the prepared Class A slurry and Class B slurry into the slurry storage tank (1) through the grouting interface (4); S5, the device for injecting slurry is brought to the location where construction is required by means of a mobile vehicle (34), and the stirring motor (2) is turned on to stir the slurry again in the slurry storage tank (1) to prevent sedimentation and uneven distribution due to time problems; the adjustable pressure grouting pump (3) and the valve at the connection between the grouting pump and the grouting hose (9) are turned on to adjust the grouting amount and grouting pressure of the Class A slurry and the Class B slurry as required; S6, providing a grouting hose (9), wherein both ends of the grouting hose (9) are respectively connected to an adjustable pressure grouting pump (3) and a double slurry grouting device; S7, drilling a hole on the ground at a predetermined location of the underground water leakage plugging place with a drilling rig, and lowering the double-screw liquid grouting equipment to a predetermined grouting position in the borehole; S8, the double slurry enters the adjustable pressure grouting pump (3) through the slurry storage tank (1), and then is pressurized by the adjustable pressure grouting pump (3) and flows into the grouting hose (9), and then enters the underground double slurry grouting equipment through the grouting hose (9), and the type A slurry and the type B slurry are mixed again by the push-in screw rod (19), and are injected into the compressed soil under pressure, so as to achieve the purpose of repairing the pores; S9. After the grouting is completed, the Y-shaped grouting pipe and the first through hole (13) are cleaned promptly by flushing equipment.
