Technical Field
The utility model relates to a construction field, in particular to underground works's construction technology specifically is a slurry shield construction mud is carried and is dealt with the component.
Background
At present, with the rapid development of the traffic infrastructure of China, the number of shield tunnel projects is continuously increased. The slurry balance shield adopts a soil discharging mode of pipeline slurry conveying, is suitable for various stratums, has high safety, and is commonly used for high water pressure and large section projects such as cross-sea and river-crossing projects and projects with high sedimentation control requirements. The mud delivered by the mud discharge pipe of the mud circulation system contains various types of muck particles dug from an excavation surface, and the particles can abrade and even block the pipeline in the delivery process. The pipeline of the slurry circulation system can turn due to the limitation of the field, and a vortex area is formed at the turning position of the fluid, so that the turbulence intensity is high, the movement condition of the slag particles is complex, the abrasion of the pipeline is increased, and the possibility of pipe blockage is greatly increased. The range of the swirl zone is related to the turning angle, if the turning angle is smaller, such as close to 90 degrees, the range of the swirl zone is larger, the fluid turbulence intensity is also larger, even serious faults such as pipeline wearing-through and the like can occur, adverse effects are caused to the engineering, and the requirements of high efficiency, high speed and long distance tunneling generally proposed in the current engineering are difficult to meet.
SUMMERY OF THE UTILITY MODEL
To the problem, the utility model aims to provide a wearing and tearing that cause the pipeline when minimize mud is carried and the possible slurry shield construction mud of jam pipeline are carried and are dealt with the component. The technical scheme is as follows:
