Small-size cutter-suction boat and pump boat two-parallel and one-series blow filing system and construction method of small-size cutter-suction boat and pump boat two-parallel and one-series blow filing system

Abstract

The invention relates to a small-size cutter-suction boat and pump boat two-parallel and one-series blow filing system and a construction method of the small-size cutter-suction boat and pump boat two-parallel and one-series blow filing system, and belongs to the technical field of dredge engineering. The small-size cutter-suction boat and pump boat two-parallel and one-series blow filing system is formed in a way that a main cutter-suction boat is connected in parallel with a sub cutter-suction boat and is connected in series with a relay pump boat, a pump boat mud discharge pipeline is connected to a mud discharge push field, and the mud discharge pipeline is provided with an exhaust valve. According to the construction method of the small-size cutter-suction boat and pump boat two-parallel and one-series blow filing system, the main cutter-suction boat and the sub cutter-suction boat are used for building relationship with the pump boat. The method comprises the following construction steps including (1) engine standby: when the main cutter-suction boat requires engine standby, the sub cutter-suction boat and the relay pump boat carry out engine standby; (2) pump merging: the main cutter-suction boat and the sub cutter-suction boat carry out pump merging, the pump boat carries out pump merging after the mud discharge pipeline discharges out clear water, and the normal blow filling construction is carried out; (3) off-pump: the slurry concentration is reduced through the main cutter-suction boat and the sub cutter-suction boat until the clean water is pumped out, the relay pump boat realizes the pump-off, and the main cutter-suction boat and the sub cutter-suction boat realize the pump-off. The system and the method provided by the invention have the advantages that the boat engine arrangement is reasonable, the operation is convenient, the construction is safe, the integral efficiency is high, and the like.

Description

technical field [0001] The invention belongs to the technical field of dredging engineering, and in particular relates to a dredging and reclamation system of two small cutter suction boats and pump boats in parallel and a construction method thereof. Background technique [0002] At present, there are many rivers, lakes and lakes, and the rivers are seriously polluted. The lakes need to remove the polluted sediment, and some dredging projects are often carried out. Some ecological dredging projects are mainly in the urban areas of large and medium-sized cities, and lakes in tourist attractions. The dredging projects usually have a row distance The characteristics of long life and high environmental protection requirements. Whether the flow rate of the relay pump ship and the environmental protection cutter suction ship matches in the long-displacement construction is related to the full play of the equipment function in the construction, otherwise it will cause restrictions...

Problems solved by technology

Whether the flow rate of the relay pump ship and the environmental protection cutter suction ship matches in the construction of long row distance is related to the full play of the equipment function in the construction, otherwise it will cause restrictions and waste to the play of the equipment function

The existing dredging and reclamation systems for construction of cutter suction ships and pump ships have simple layout and low overall construction efficiency, and the energy efficiency of the system cannot be fully and effectively used. At the same time, equipment damage and construction interruption are likely to occur due to improper construction, resulting in increased construction costs and affecting Technical issues such as construction efficiency
