[0063] In one embodiment, Figure 1 As shown, the sensor assembly 4 includes a distance sensor 401 , a positioning sensor 402 , and a pressure sensor 403 . The distance sensor 401 is arranged on the ballast assembly 2 , the positioning sensor 402 is arranged on the frame 1 , and the pressure sensor 403 is arranged on the frame 1 .

[0064] Specifically, in this embodiment, the distance sensor 401 is installed at the bottom of the ballast tank 201. The distance sensor 401 adopts a laser ranging sensor, which measures the displacement change of the underwater casting device relative to the seabed or structure through the laser ranging sensor, and monitors the horizontal and vertical displacement of the underwater casting equipment relative to the reference plane.

[0065] In this embodiment, the positioning sensor 402 is a GPS sensor, which is used to determine the overall position.

[0066] In this embodiment, the pressure sensor 403 includes a first pressure sensor 403 and a second pressure sensor 403, wherein the first pressure sensor 403 is installed on the connecting pipe 501 near the pouring head 502, and is used to detect the pressure inside the pipe; the second pressure sensor 403 is installed on the frame 1, and is in a horizontal position with the first pressure sensor 403, and is used to detect the external water pressure; the pressure sensor 403 transmits the collected data to the processor 407 for real-time comparative analysis to monitor the slurry pumping status during the construction process.

[0070] Specifically, in this embodiment, the monitor 6 is equipped with infrared or low-light enhancement technology to adapt to the underwater low-light environment and improve the monitoring effect.

[0073] According to an embodiment of the present invention, on the other hand, Figure 3 As shown, an underwater pouring method is also provided, which is applied to the above-mentioned underwater pouring device, and the pouring method includes the following steps:

[0074] S1: According to the project to be poured, select a suitable pouring head 502 and place the underwater pouring device into the water as needed.

[0075] Specifically, in this embodiment, during underwater pouring operation, the connecting pipe 501 is first connected to the delivery pipe on the water surface, and the pumped slurry is sent into the connecting pipe 501. In the early stage of construction, the pouring head 502 can be replaced according to actual construction conditions and needs to meet the corresponding operation requirements.

[0076] S2: Obtain construction environment parameters.

[0077] Specifically, according to the content of the work to be constructed, various parameters of the construction environment are obtained and input into the processor 407. The device is checked to see if the overall connection is complete. If welding defects or overall structural deviation are found, the underwater pouring device needs to be reassembled.

[0078] At the same time, check whether the first connecting line 405 and the second connecting line 406 are properly connected. Test each sensor and electric device to ensure that they are within the normal operating range. If any function is found to be malfunctioning, replace them promptly. Also check the sealing of each connection point to ensure normal working performance underwater.

[0079] S3: According to the construction conditions, the ballast assembly 2 is controlled to allow the underwater casting device to enter the water as a whole, and the displacement change of the underwater device relative to the seabed or structure is measured according to the sensor assembly 4 to monitor the horizontal and vertical displacement of the underwater casting device relative to the reference plane.

[0080] Specifically, after assembly is completed onshore or on a construction vessel, the entire underwater pouring device is placed in the construction waters, the pouring head 502, the driver 3, and the water supply and drainage components 202 are submerged in water, and construction environment parameters, including but not limited to coordinates, altitude, and water temperature, are collected.

[0081] According to the construction conditions, the water inlet and outlet parts 202 are controlled to absorb water and compress, so that the underwater casting device as a whole enters the water, and the displacement changes of the underwater casting device relative to the seabed or structure are measured based on the positioning sensor 402 and the distance sensor 401 to monitor the horizontal and vertical displacements of the underwater casting device relative to the reference plane.

[0082] S4: After the underwater pouring device descends to the designated position, the driver 3 is controlled to move the underwater pouring device according to the construction route.

[0083] Specifically, when the underwater pouring device descends to the designated position, the driver 3 controls underwater propulsion and direction change, so that the propeller on the driver 3 rotates and moves according to the construction route, and the positioning sensor 402 is used to detect the posture of the entire device.

[0084] S5: After completing the pre-casting preparations, start pumping the slurry, and the sensor assembly 4 collects the slurry pressure parameters and the ambient water pressure at the same time.

[0085] Specifically, after the pre-casting preparations are completed, the slurry is pumped. When the slurry passes through the pressure sensor 403, the pressure parameters are collected, and the ambient water pressure is collected at the same time.

[0086] S6: After the construction is completed, the slurry in the casting assembly 5 needs to be further drained.

[0087] Specifically, after the construction is completed, the slurry in the connecting pipe 501 needs to be further drained. At this time, the pressure sensor 403 and the temperature sensor 404 can be used to compare the temperature and pressure in the water environment to detect whether it is in the draining state.

[0088] S7: control the ballast assembly 2 and the driver 3 to make the underwater pouring device float up and reach the designated position for recovery.

[0089] Specifically, the ballast assembly 2 is controlled to discharge ballast water to make the device float up, and the driver 3 is controlled to move the underwater pouring device to the designated position for recovery.

[0090] In one embodiment, after the step S5: the preparation work before pouring is completed, the pumping of the slurry is started, and the sensor assembly 4 collects the pressure parameters of the slurry and the environmental water pressure at the same time, which includes the following steps:

[0091] S501: determine whether the pressure value obtained by the sensor assembly 4 meets the preset value.

[0092] Specifically, if the pressure sensor 403 detects that the pressure in the connecting pipe 501 suddenly increases and is much higher than the environmental water pressure, it is necessary to consider whether there is a blockage problem in the connecting pipe 501, and the construction needs to be stopped in time and checked. When the environmental water pressure suddenly changes, it is necessary to consider whether the underwater pouring device suddenly sinks, at which time the displacement of the underwater pouring device relative to the seabed or structure is measured by the distance sensor in combination with the positioning sensor 402.

[0093] S502: determine whether the temperature value obtained by the sensor assembly 4 meets the preset value.

[0094] Specifically, when pumping the slurry, the temperature sensor 404 monitors whether the temperature of the slurry is stable, wherein the temperature sensor can be a thermistor temperature sensor 404, which measures temperature by the characteristic that the resistance value of a semiconductor material changes significantly with temperature. And by monitoring the temperature of the external water environment, it is evaluated whether it is suitable for underwater solidified soil pouring construction.

[0095] When a large increase in the temperature in the connecting pipe 501 is found, it is necessary to consider whether there is a blockage problem in the connecting pipe 501, or the slurry proportioning changes, or the mixing is uneven, which causes early hydration, so it is necessary to stop in time and check. If the environmental water temperature changes, it is necessary to consider whether the temperature change range is still suitable for the solidified soil construction, and when the change exceeds the applicable range, it is necessary to consider replacing the mix proportion to adapt to the change of the underwater temperature.

[0096] Although the embodiments of the present application are described in combination with the drawings, various modifications and variations can be made by those skilled in the art without departing from the spirit and scope of the present application, and such modifications and variations all fall within the scope defined by the appended claims.
