Embodiment

[0026] A pipeline structure for sand blowing and sea reclamation by dredgers, refer to figure 1 As shown, it includes a hull 1 , a mud tank 2 located at the bottom of the hull 1 , a suction pipeline mechanism 3 , a drainage pipeline structure 8 , and a filling pipeline structure 4 . The suction pipeline mechanism 3 is connected to the hull 1 and communicates with the mud tank 2, and a power device 5 is arranged in the mud tank 2. This power unit 5 is a mud pump.

[0027] refer to figure 2 , one side of the hull 1 is provided with a connection port 9 for detachably connecting the rake suction pipeline mechanism 3 . The connection port 9 is used for the common use of mud and sand water in and out. During the raking operation, the raking suction pipeline mechanism 3 is assembled to the connection port 9, and the power device 5 forms a negative pressure power at the connection port 9, so that the mud and water are drawn away and enter the output pipe of the power device 5 roa...

Abstract

The invention discloses a dredger sand blowing and sea filling pipeline structure, and belongs to the technical field of dredgers. The problems of operation efficiency and reliability are solved. According to the technical scheme, the dredger sand blowing and sea filling pipeline structure comprises a dredger body, and a mud cabin, a drag suction pipeline mechanism, a drainage pipeline structure and a blowing and filling pipeline structure which are located at the bottom of the dredger body, the dredger sand blowing and sea filling pipeline structure is characterized in that the drag suction pipeline mechanism is connected to the dredger body and communicates with the mud cabin, and a power device is arranged in the mud cabin; one side of the dredger body is provided with a connecting portused for being detachably connected with the drag suction pipeline mechanism, the connecting port is used for sediment water to flow in and out, the connecting port is connected with the power devicethrough a straight pipe, the power device provides power to achieve sediment suction or sediment discharge of the drag suction pipeline mechanism, a pipeline connector of the power device is connected with the drainage pipeline structure and the blowing and filling pipeline structure correspondingly, and the effect of improving the operation efficiency and the working stability is achieved.

Description

technical field [0001] The invention relates to the field of dredgers, in particular to a pipeline structure for sand blowing and sea reclamation of dredgers. Background technique [0002] Sand blowing reclamation is to build up land by blowing sand around the reclamation point, which is different from traditional excavation and transportation, and also different from dredging and transportation. No pipes are needed for short-distance sand blowing, but long-distance sand blowing requires pipes of different lengths, the longest extending for more than ten miles. [0003] For sand blowing and sea reclamation, the pumps (some with long pipes) of dredgers (some with sand dredgers) are used to blow the sand and water from the seabed outside the circle into the target circle together, and the seawater flows out of the circle, and the sand stays in the circle. Gradually, the sea surface in the circle was filled with land by the continuously blown sand. [0004] Whether to enclose...
