Description

Technical Field

[0001] The utility model relates to the technical field of underwater silt clearing, in particular to an underwater hard mud flushing device and a ship flushing system. Background Art

[0002] At present, when conducting underwater operations, caisson operations are often carried out first. The caisson has partitions inside and can float in the water. The sinking or floating of the caisson can be controlled by adjusting the ballast water in the caisson. The caisson is set to provide a support foundation for subsequent construction operations or to intercept water flow. For example, the dock gate at the entrance and exit of the dock is a type of caisson structure. During construction operations, sinking and floating operations are often required.

[0003] Since caissons often sink and float, underwater silt tends to harden after the caissons sink multiple times. After the underwater silt hardens, it will affect the accuracy of the caisson's sinking to the bottom. If you want to completely clean out the silt, you often need to use large equipment or manual underwater cleaning. The use of large equipment is not only costly, but also inefficient, while manual underwater operations are not only time-consuming and labor-intensive, but also have certain risks.

[0046] Example 2

[0047] like Figure 5 As shown, based on Example 1, this embodiment discloses a ship flushing system, including a ship 10 and an underwater hard mud flushing device described in Example 1;

[0048] The ship 10 is provided with a boom 50, and the boom 50 suspends the strip 4 through a steel wire rope 40;

[0049] The ship 10 is also provided with a high-pressure water pump 20 , which is used to provide pressurized water flow to the flushing pipeline 2 .

[0050] The ship flushing system of this embodiment suspends the strip 4 through the boom 50 on the ship 10, so that the flushing device can be suspended under the boom 50, and the high-pressure water pump 20 on the ship 10 provides pressurized water flow for the flushing pipe 4. During actual construction, the boom 50 suspends the strip 4 through the wire rope 40, and the flushing device is vertically placed on the hard mud 60 or suspended above the hard mud 60.

[0051] A preferred embodiment further comprises a water supply pipe 30, one end of which is connected to the high-pressure water pump 20, and the other end of which is connected to the flushing pipe 2. The high-pressure water pump 20 is connected to the flushing pipe 2 through the water supply pipe 30, wherein the water supply pipe 30 is connected to the joint 1 of the flushing pipe 2.

[0052] This embodiment also discloses a construction method of a ship flushing system, comprising the following steps:

[0053] Step 1: Several high-pressure water pumps 20 are installed on the ship 10 according to the construction conditions. A control box is provided on the ship 10 to adjust the working state of the high-pressure water pump 20 according to the conditions. To ensure the safety of electricity use, the control box must meet the requirements of temporary power construction specifications, implement the safety measures of "one box, one leak, one machine, one gate", and take waterproof measures;

[0054] Step 2: Use the water supply pipe 30 to connect the high-pressure water pump 20 to the flushing pipe 2 of the flushing device. When connecting, connect the water supply pipe 30 to the joint 1 of the flushing pipe 2. During the process, the pipe mouth should be fixed to prevent leakage from affecting the flushing pressure and falling off to increase the maintenance intensity. After inspection and confirmation, use the boom 50 of the ship 10 to hoist the flushing device. The boom 50 is connected to the lifting ear 3 of the strip 4 through the wire rope 40, and then slowly placed in the water until the base of the strip 4 contacts the bottom of the hard mud 13 to play a supporting role. At the same time, place the high-pressure water pump 20 in the water along the edge of the ship and tie it up;

[0055] Step 3: After checking and confirming that it is safe and normal, turn on the control switch of the high-pressure water pump 20 in turn, and the water source is pumped by the high-pressure water pump 20 through the water supply pipe 30, the flushing pipe 2, and the flushing gun head 6 to form water pressure to flush the hard mud 60. The flushing working condition can be controlled by adjusting the number of high-pressure water pumps 20 and the displacement of the ship 10. When encountering hard mud 60 with uneven height, the amplitude of the boom 50 can be adjusted, and the lifting control of the wire rope 40 has reached the best construction state;

[0056] During the flushing process, pay attention to record the spacing of the ship's 10 displacements, single-point flushing time, water pump usage, lifting height, etc. After multi-point flushing, have divers go into the water to check the flushing effect and summarize the optimal construction parameters based on the actual flushing conditions in order to further improve construction efficiency and quality.
