Description

Technical Field

[0001] The utility model relates to the technical field of sand spreading, and more specifically to a sand spreading pipe device capable of improving the flatness of sand spreading. Background Art

[0002] At present, land reclamation mainly relies on dredgers, that is, dredgers are used to fill the sea with gravel or soil to achieve the purpose of land reclamation. However, due to the single output direction of existing dredgers, the sand spreading mainly relies on the movement of the ship to achieve the purpose of uniform distribution. However, when the ship is in the river, it is easy to cause its output to be unbalanced due to the external force, thereby affecting its sand spreading effect and affecting the stress of the original foundation of the reclamation area.

[0003] In response to the above-mentioned problems, Chinese patent CN208870039U provides a T-shaped sand-laying tube, which is provided with a plurality of sand-laying openings on the sand-laying tube, and arc-shaped grooves are respectively installed on both sides of the sand-laying openings. The arc-shaped grooves are used to form a slideway, and an adjusting baffle is slidably installed in the slideway formed by the arc-shaped grooves. The size and relative angle of the sand-laying opening can be changed by pushing the adjusting baffle, thereby achieving adjustment of the sand-laying angle and the amount of sand discharged, and avoiding the problem of excessive concentration of sand that requires later flattening.

[0004] However, during use, it was found that the above structure has two main sand spreading openings, the sand spreading efficiency is relatively low, and when the conveying speed is fast, if the adjustment is not timely, backfilling will still cause arching and silting of the lower soft soil. Utility Model Content

[0005] The utility model provides a sand spreading pipe device for improving the flatness of sand spreading, so as to solve the problems that the existing barge sand spreading system has fewer sand spreading openings resulting in low sand spreading efficiency and easily causes arching and silting of the lower soft soil when the sand output is small.

[0006] According to one aspect of the utility model, a sand-laying pipe device for improving the flatness of sand laying is provided, comprising a floating body and a main pipe connected to a ship pipeline, the floating body being a plurality of pipe bodies arranged at intervals and welded at both ends of the main pipe, the free ends of the pipe bodies being sealed, a plurality of sand-laying branch pipes being arranged at intervals on the main pipe, and the angle between the sand-laying branch pipes and the horizontal plane being 15°.

[0007] Preferably, based on the above solution, the number of the pipe bodies is 8, which are symmetrically welded at two sides of the main pipe.

[0008] Preferably, based on the above solution, a plug is provided at the end of the main pipe.

[0009] Preferably, based on the above scheme, it further comprises a steel platform, and the middle part of the steel platform is welded to the main pipe.

[0010] Preferably, based on the above solution, flanges are provided on the main pipe and the pipe body, the pipe body is welded to the steel platform via the flange, and the main pipe is connected to the ship pipeline via the flange.

[0011] Preferably, based on the above solution, the main pipe and the pipe body are both steel pipes with a diameter of 700 mm.

[0012] Preferably, based on the above solution, brackets are welded between the tubes.

[0013] The utility model discloses a sand laying pipe device for improving the flatness of sand laying. The main pipe is connected with the ship pipeline to receive the mud and sand transported by the sand pumping ship. A plurality of sand laying branch pipes can be used to achieve high-precision and uniform laying, which not only improves the sand laying efficiency but also effectively avoids the excessive concentration of water head stress of the traditional blowing and filling pipe head during sand laying, which leads to the arching and silting phenomenon of the lower soft soil, thereby achieving uniform laying of mud and sand.
