Mud discharge and blockage prevention device for mud-water balance top pipes

Abstract

The invention relates to a mud discharge and blockage prevention device for mud-water balance top pipes. The device comprises a mud inlet and outlet part, a mud storage part and a mud block cutting part; a bin cover plate is arranged at the top of a mud storage bin of the mud storage part; a mud inlet and a mud outlet of the mud inlet and outlet part are formed in two sides of the upper part; a power device is mounted at the bottom; a spiral cutter head of the mud block cutting part is arranged inside, and is connected with the power device; the power device is connected with a PLC control system of the mud block cutting part; and the PLC control system controls the power device to drive rotation of the spiral cutter head. Larger mud blocks in mud discharge pipes are remained in the mud storage bin through a mud filter screen; the designed PLC system is sued for controlling the spiral cutter head to cut the mud blocks as mud slag; and the mud slag continuously enters the mud dischargepipes along with water flowing power, so that the blockage of the mud discharge pipes of the top pipes caused by accumulation of the large mud blocks discharged in the pipes is prevented, and the difficulty of construction stop caused by blockage of the mud discharge pipes of the mud-water balance top pipes is solved.

Description

technical field [0001] The invention relates to a mud-water balance pipe jacking construction device, in particular to a mud-water balance pipe jacking and anti-blocking device. Background technique [0002] The mud-water balance pipe jacking construction is a commonly used pipe jacking method for pipe laying through the jacking of the rear seat jack and the excavation of the front roadheader. The mud discharge method is that the front cutter head cuts the soil, and the cut soil clods are combined with the pressure water to form mud water, and then the mud is discharged through the pipeline. Since there must be large soil clods in the formed mud water, the rapid accumulation of mud clods during the mud discharge process will cause the mud discharge pipeline to be blocked or even blocked, resulting in the stagnation of the whole line and affecting the progress of the project. [0003] At present, the solution to pipeline blockage in the process of pipe jacking construction i...

Since there must be large clods in the formed mud water, the rapid accumulation of mud clods during the mud discharge process will cause the mud discharge pipeline to be blocked or even blocked, resulting in the stagnation of the entire line and affecting the progress of the project

[0003] At present, the solution to pipeline blockage in the process of pipe jacking construction is to shut down and check and clean each section of the pipeline section by section, which greatly wastes manpower and material resources and takes a long time, which has a significant impact on the progress of the project.
