Description

Technical Field

[0001] The invention relates to a method for floating a mud discharge pipe. Background Art

[0002] A certain enterprise has five sedimentation tanks, which mainly provide water for the enterprise's production and play a role in regulating and buffering in response to extreme situations. This sedimentation tank operates throughout the year. From May to November every year, a dredger is used to dredge and discharge the sediment in the tank. The dredger's discharge pipe is made of PE material and connected by flanges. Each mud discharge pipe is about 250m long. The mud discharge pipe needs to be supported by a float to float the pipe on the water surface. There are many types of mud discharge pipe floats. The original floats include iron empty barrels, plastic empty barrels, etc., but the shortcomings are also very obvious. Iron is easy to corrode and leak, and loses its floating effect. Plastic barrels are easy to leak in complex environments due to bumps and also lose their floating effect. The hollow buoy is transformed into a high-density polyethylene floating module to avoid damage and water ingress due to bumps. Through precise measurement, the risk of the mud discharge pipe breaking or dead bends that hinder the medium transportation is also avoided, ensuring smooth dredging.

[0003] Closest document: CN201671128U A horizontal floating mud discharge pipe buoy

[0004] Comparative analysis: Although both involve setting up floating devices for water pipelines to meet the requirements of medium transportation, the research on the construction of floats is different. The existing patent CN201671128U is also a hollow buoy, and the float of this patent is a high-density polyethylene floating solid module, which can avoid damage from bumps and water ingress. Summary of the invention

[0005] The purpose of the invention is to provide a method for floating a mud discharge pipe, which solves the problem of folding of the hose at the pipe connection.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0007] The present invention provides a method for floating a mud discharge pipe, comprising: installing a float at both ends of each pipe, controlling the installation position of the float to ensure that when the mud discharge pipe is bent by 90°, the float has a supporting effect on the bending of the hose, and ensures that the bending of the hose is not greater than 90°;

[0008] The floating body adopts a steel frame structure, and buoys are fixedly arranged at both ends of the steel frame structure. The buoys are solid high-density polyethylene floating modules.

[0009] Furthermore, the outer dimensions of the floating module are 80*50*40 cm.

[0010] Furthermore, the buoyancy of the floating module reaches 135 kg.

[0011] Furthermore, by calculating the length and spacing of the two floats, it was determined that when the floats were installed at a distance of Hmm from the inner side of the flange of the mud discharge pipe, the outer corners of the two floats could contact and support each other to ensure that the mud discharge pipe was bent no more than 90°.

[0012] Furthermore, the distance between the two floating bodies is 2200 mm.

[0013] Furthermore, two floats are respectively installed at both ends of the mud discharge pipe at a distance of 500 mm from the inner side of the flange, and the length of the mud discharge pipe between the two flanges is 1200 mm.

[0014] Compared with the prior art, the beneficial technical effects of the present invention are:

[0015] Instead of plastic buoys, high-density polyethylene floating modules are used (this type of float has the characteristics of corrosion resistance, oxidation resistance, pollution-free, and impact resistance.

[0016] (1) Solved the problem of collision damage of plastic barrels and iron barrels;

[0017] (2) Solved the problem of hose folding at the pipeline connection;

[0018] (3) A set of such devices is installed at both ends of each pipe, so that the hose can be folded to the greatest extent without forming a dead angle. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The present invention will be further described below in conjunction with the accompanying drawings.

[0021] Figure 2 This is a demonstration diagram of the mutual support of the floating bodies after the mud discharge pipe is bent. DETAILED DESCRIPTION

[0022] like Figure 1 and 2 As shown, a method for floating a mud discharge pipe comprises: installing a float at each end of each pipe, and controlling the installation position of the float to ensure that when the mud discharge pipe is bent by 90°, the float has a supporting effect on the bending of the hose, ensuring that the bending of the hose is not greater than 90°;

[0023] The floating body adopts a steel frame structure, and buoys are fixedly arranged at both ends of the steel frame structure. The buoys are solid high-density polyethylene floating modules.

[0024] The floating module has an overall size of 80*50*40 cm.

[0025] The buoyancy of the floating module reaches 135 kg.

[0026] By calculating the length and spacing of the two floats, it is determined that when the floats are installed at a distance of Hmm from the inner side of the flange of the mud discharge pipe, the outer corners of the two floats can contact and support each other to ensure that the mud discharge pipe is bent no more than 90°.

[0027] The distance between the two floating bodies is 2200 mm, that is, the two floating bodies are respectively installed at both ends of the mud discharge pipe 500 mm away from the inner side of the flange, and the length of the mud discharge pipe between the two flanges is 1200 mm.

[0028] The floating body is fixed with a steel frame structure to improve strength, and each floating body adopts double support to avoid distortion and other collision damage.

[0029] As attached Figure 2 As shown in the figure, when the mud discharge pipe bends, the two floats will approach each other and support each other to form a mutual support effect, thereby preventing the mud discharge pipe from bending further and ensuring that the hose bends no more than 90°. Since the buoy of the float does not use a plastic float barrel, but a solid high-density polyethylene floating module, it is not only corrosion-resistant, anti-oxidation, pollution-free, but also impact-resistant, effectively solving the problem of hose folding at the pipe connection; a set of such devices is installed at both ends of each pipe, which can maximize the hose not folding into a dead angle when the hose is folded.

[0030] The embodiments described above are only descriptions of the preferred modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
