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

Embodiment 1

[0032] A small-sized cutter suction ship and pump ship in parallel to blow fill system, the main cutter suction ship and auxiliary cutter suction ship are connected in parallel, and a relay pump ship is connected in series, the main cutter suction ship and auxiliary cutter suction ship are equipped with The pump control switch, the mud discharge pipeline of the pump ship is connected to the mud discharge push field, and the mud discharge pipeline is equipped with an exhaust valve.

[0033] The mud discharge pipelines of the main cutter suction ship and the auxiliary cutter suction ship are connected by an upper mud discharge pipeline and a lower mud discharge pipeline. The mud discharge pipelines of the main cutter suction ship and the auxiliary cutter suction ship are connected in series with the pump ship, and the inlet pressure of the pump ship is 0.5-1.5 bar.

[0034] When carrying out dredging and filling construction operations in this embodiment, the connection of const...

Embodiment 2

[0038] The construction method of two small cutter suction ships and pump ships paralleling one series blowing and filling system uses the main cutter suction ship to establish contact with the auxiliary cutter suction ship and the relay pump ship, and coordinates the operations of vehicle preparation, pump combined construction, and pump off shutdown operations, including the following Construction steps:

[0039] 1. Spare vehicles: When the main cutter suction ship needs to prepare vehicles, the auxiliary cutter suction ship and the relay pump ship are ready; the relay pump ship opens the exhaust valve of the mud discharge pipe;

[0040] 2. Pumping: After the auxiliary cutter suction ship and the relay pump ship are ready, the main cutter suction ship and the auxiliary cutter suction ship are combined with the pump at the same time, and gradually accelerate to the specified speed of the mud pump diesel engine; the mud discharge pipeline of the relay pump ship exhausts After ...

Embodiment 3

[0043] The construction method of small cutter suction boats and pump boats paralleling a series blowing and filling system, using the main cutter suction boat to establish contact with the auxiliary cutter suction boat and the relay pump boat, coordinate the operation of vehicle preparation, pump construction, and pump detachment parking, specific operations Including the following construction steps:

[0044] 1. Start to prepare the vehicle according to the following steps:

[0045] ①Before the system is started, the main cutter suction dredger shall notify the standby truck, and the auxiliary cutter suction dredger and the relay pump ship shall immediately prepare the truck. At the same time, the relay pump ship shall open the exhaust valve on the mud discharge pipe at the rear of the pump ship.

[0046] ② After the auxiliary cutter suction dredger and the relay pump ship are ready, immediately inform the main cutter suction dredger that the preparation is complete and the ...

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...
