Problems solved by technology

When the blockage is serious, it is necessary to perform manual gas cutting, ship discharge, and manual repair welding for many times, until the blocked dredged soil is completely discharged, but this method takes a long time; it will cause a certain degree of damage to the steel pipe; it needs to be arranged More personnel are required for unblocking work; more materials and equipment are required; there are certain safety risks; especially when unblocking pipelines in underwater, tidal flat areas, and pipelines in areas subject to ebb and flow, it takes time, manpower, material resources, Financial resources are even greater, and have a greater impact on the development of the project; therefore, in order to solve the above problems, it is urgent to develop a new anti-clogging special mud discharge steel pipe for cutter suction ships

Abstract

The invention discloses a dredger-used blockage-proof special mud discharging steel pipe. The dredger-used blockage-proof special mud discharging steel pipe comprises a steel pipe body, wherein a discharging hole is formed in the side surface of the steel pipe body at the position close to the middle section; a middle section connecting part is welded to the position above the discharging hole; a rubber mat and a handle cover plate are mounted above the middle section connecting part; the handle cover plate is arranged above the rubber mat. The invention further provides a sewage discharging and dredging treating method of the dredger. The dredger-used blockage-proof special mud discharging steel pipe, provided by the invention, can be used as a steel pipe fixed point check opening, personnel can enter the inner part of the pipeline of a ship conveniently during work stoppage to check the wearing condition of the pipeline; a special inner thickness measuring point is arranged, and the wearing condition can be observed directly; the pipeline which has severe wearing condition and cannot be repaired conveniently from the outside can be treated by attaching plate and welding from the inner part, so that the service life of the steel pipe is prolonged.

Description

technical field [0001] The invention belongs to the field of steel pipes, and in particular relates to a special-type anti-clogging mud discharge steel pipe for a cutter suction ship and a sewage dredging treatment method for the cutter suction ship. Background technique [0002] When a large cutter suction ship excavates clay, due to the high viscosity of the clay, when the cutter suction ship transports this type of dredged soil, it is easy to cause the clay to block the steel pipe. When the cutter suction ship excavates clay and is about to block the pipe, the traditional anti-blocking measures mainly rely on the superb skills and rich experience of the cutter suction ship driver, by reducing the concentration of dredged soil, increasing the speed of the dredger Measures such as pump pressure relief to force the blocked dredged material to be discharged from the pipe head; this method can avoid the occurrence of pipe blockage to a certain extent, but the success rate cann...
