Description

An underground frozen hole drilling mud filtration and recovery device

Technical field

The invention belongs to the technical field of mud recycling, and is specifically a mud filtration and recovery device for drilling underground frozen holes.

Background technique

With the rapid development of urban underground spaces such as subway tunnels, the geotechnical environment faced by underground space construction is becoming increasingly complex. The construction risks of projects such as water-rich, weak, and unstable strata have increased significantly, and the freezing method, as a special stratum reinforcement construction method, is currently a reliable construction solution to solve such engineering problems. It has the advantages of high reinforcement strength, good water sealing performance, and small ground deformation. It is increasingly used in the field of urban underground space engineering.

Drilling frozen holes is the first step and key process in the implementation of the freezing method. During the drilling process, drilling mud circulation plays the role of carrying drilling slag, balancing ground pressure, and cooling and lubricating drill bits and drilling tools. When drilling a frozen hole, the mud prepared in the slurry storage tank is pressed into the bottom of the hole from the inside of the drill pipe under the action of the grouting pump, and then flows through the drill bit and carries drilling residue and cuttings into the connection between the drill pipe and the formation. The annular space is finally discharged from the orifice to the mud slag removal and sedimentation tank under the action of pump pressure. The mud in the recovery tank is pumped to the slurry storage tank after sand fishing, slag removal, and sedimentation to continue to participate in the cycle.

The mud recovered in the prior art contains a lot of residue and gravel particles. In the prior art, an electric mud vibrating screener is often used to screen the mud. The exciting force generated by the vibration source is transmitted to the screen box through the screen box. On the screen surface inside, the excitation force generated by the vibrator is a longitudinal force, which causes the screen box to drive the screen surface to move longitudinally back and forth, thereby screening out the residue. However, because the mud has a certain adhesion, the residue particles The different sizes make it difficult to screen out the residue particles from the mud, resulting in poor screening effect of the existing technology. An underground frozen hole drilling mud filtration and recovery device is proposed to solve the above problems.
