Description
Technical Field
The invention belongs to the technical field of dredging engineering equipment, and particularly relates to a pipeline connecting and fixing device and a pipeline connecting and fixing method.
Background
In dredging works, the steel sludge discharge pipe serves to transport fluids. When the steel sludge discharge pipe is used for conveying fluid, no matter on water, underwater immersed pipes or on shore, when a conveying pipeline is connected with uneven fluctuation and an angle, the rubber sludge discharge pipe is required to be used for soft connection. Therefore, the rubber sludge discharge pipe is an essential accessory for construction operation of dredging engineering. The rubber sludge discharge pipe is formed by connecting a steel flange short pipe and a wear-resistant and pressure-resistant rubber pipe, and then the steel flange short pipe is connected with the steel sludge discharge pipe for use. The sludge discharge pipe is operated in a high-pressure environment when in use; therefore, certain fastening requirements are required for the connection between the steel flange short pipe and the rubber pipe. The connection fixing mode in the prior art is as follows: the screens usage is done to steel flange nozzle stub outer wall welding round steel, and during the staff squeezed into the rubber nozzle stub with the nozzle stub, according to the round steel screens position of steel flange nozzle stub, at rubber hose outside staff through two clamps, the screw is turned round tightly, and the fastening clamp, and then the connection of fastening steel flange nozzle stub and rubber tube. The mode of connecting and fixing has the defect that the locking force of the rubber pipe and the flange short pipe is insufficient, so that the flange short pipe and the rubber pipe are easy to loosen due to the pressure in the pipeline when in use. The connection of the steel sludge discharge pipe is as follows: the top water pipe (underwater, water surface) and the top land pipe. Once the rubber sludge discharge pipe is loose due to loose connection, a new rubber sludge discharge pipe needs to be replaced to normally operate. The replacement of the rubber mud pipe is not only time-consuming, but also needs manual operation and hoisting and replacement matched with hoisting equipment. The rubber mud pipe of the water top pipe (underwater immersed pipe and water surface floating pipe) is replaced more time-consuming and has higher cost compared with the land pipe due to more environmental factors. Therefore, whether the rubber mud pipe is fastened or not is related to the engineering progress and the construction cost of the dredging engineering.
