Description
TECHNICAL FIELD
[0001] The utility model relates to a kind of anti-burying sinking pipes. BACKGROUND
[0002] To realize the new type of sinking pipe in conveying clean water, according to the static buoyancy of the sinking pipe, the weight calculation result, additional floating body is needed to be added on the basis of the existing pipe joint, so that the total buoyancy is greater than the pipe + clean water quality when conveying clean water, and the total buoyancy is less than the pipe + mud quality when conveying mud.
[0003] According to the technical index of the new anti-burying sinking pipe, the reserve buoyancy of the pipe joint after adding the floating body should not be less than 5% of the net weight of the pipe joint, so the reserve buoyancy should be greater than 5.493t×5% = 0.275t.
[0004] The self-weight of the steel floating box in the conveying clean water state is reduced by the buoyancy, which is 4.632t, and the required reserve buoyancy is not less than 0.275t, so the additional buoyancy provided by the floating body is not less than 4.632+0.275 = 4.907t. The steel floating box adopts a steel pipe with an inner diameter of 0.85m and a wall thickness of 10mm, so the required total volume is about 8.36m 3 , the total length is about 14.0m, and the total mass is about 3.481t.
[0005] However, according to the existing calculation of the buoyancy performance of the steel floating box, under the condition of meeting the 0.275t reserve buoyancy, the volume and self-weight of the steel floating box are relatively large, and the production cost is expected to exceed 35,000 yuan per unit; the production cost is relatively high; therefore, an anti-burying sinking pipe is proposed to solve the above problems. CONTENT OF THE UTILITY MODEL
[0006] The utility model aims to overcome the defects of the prior art and provide an anti-burying sinking pipe with low production cost and convenient on-site installation, layout and maintenance.
[0007] The technical scheme to achieve the above-mentioned purpose is as follows: an anti-burying sinking pipe, comprising a steel pipe, a rubber pipe, a plastic floating body and a limiting assembly.
[0008] One end of the steel pipe is connected to the rubber pipe; the middle part of the steel pipe is connected to the plastic floating body, and the limiting assembly is arranged on both sides of the plastic floating body.
[0009] Preferably, the limiting assembly comprises two limiting plates, and the two limiting plates are respectively located on both sides of the plastic floating body and connected to the outer side wall of the steel pipe.
[0010] Preferably, the steel pipe is connected to the rubber pipe through a first flange.
[0011] Preferably, the end of the steel pipe away from the rubber pipe is connected to a second flange.
[0012] Preferably, the plastic float is cylindrical.
[0013] The beneficial effects of this utility model are as follows: This anti-buried pipe adopts a 12m steel pipe + 2m rubber pipe, equipped with a plastic float, which is installed on the steel pipe. This achieves force balance during the ascent of the new type of pipe. The plastic float is installed at the center of gravity of a single set of pipes, and a limiting plate is set to restrict the lateral sliding of the float, ensuring optimal posture of the pipe during ascent and when settling on the bottom. The market price of the plastic float is 0.5 million yuan per piece, and the price of a single set is 1.0 million yuan, resulting in low cost and more convenient on-site installation, deployment, and maintenance.
