[0002] The barrel foundation is a type of foundation that penetrates the seabed by pumping water into the foundation to create a pressure difference between the upper and lower parts of the foundation cover. Due to the uneven surface of the seabed and the inability of the pumping skids used in construction to pump mud, the lower part of the foundation cover cannot effectively contact the mud surface after the barrel foundation is installed. Therefore, it is necessary to use grouting inside the barrel foundation, that is, inject grouting material into the barrel foundation to fill the space below the barrel foundation cover and increase the bearing capacity of the foundation.

[0003] However, in the related art, during the process of grouting into the barrel foundation, the grouting condition cannot be monitored in real time, resulting in uneven grouting. Summary of the invention

DETAILED DESCRIPTION

[0062] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application may be combined with each other.

[0063] The present application will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0064] In the related art, refer to Figure 1 , Figure 1 A schematic diagram of a barrel foundation is shown in FIG. Figure 1 As shown, currently, a grouting pipe 2 and an overflow pipe 3 are often installed above the top cover of the barrel foundation 1, and grouting material is input into the barrel foundation 1 through the grouting pipe 2, and then the overflow pipe 3 is observed in real time. When the overflow pipe 3 produces grouting material, it is determined that the grouting operation is completed.

[0065] However, due to the uneven sea level, when the overflow pipe 3 produces grouting material, it is impossible to ensure that the lower part of the top cover of the barrel foundation is in full contact with the grouting material, and the grouting material is often unevenly distributed inside the barrel foundation, resulting in poor grouting quality.

[0066] In view of this, the embodiment of the present application proposes a barrel foundation grouting quality monitoring system, which monitors the grouting conditions inside the barrel foundation during the grouting operation to ensure uniform grouting. Figure 2 , Figure 2 FIG. 4 shows a front cross-sectional view of a barrel foundation grouting quality monitoring system according to an embodiment of the present application, as shown in FIG. Figure 2 As shown, the monitoring system includes:

[0067] A grouting module 4, used for inputting grouting material into the barrel foundation 1;

[0068] The first sensor module 5 includes a plurality of first sensors, which are evenly arranged at the lower part of the top cover of the barrel foundation 1 and are used to collect first temperature information of the upper end of the barrel foundation 1;

[0069] The monitoring module 6 is connected to the grouting module 4 and the first sensor module 5, and is used to obtain a plurality of first temperature information collected by a plurality of the first sensors, and when it is determined that the temperature values ​​corresponding to the plurality of first temperature information are all in the first temperature interval and are consistent, send a closing signal to the grouting module 4 to drive the grouting module 4 to close;

[0070] Wherein, the first temperature range represents the temperature of the grouting material.

[0071] like Figure 2 As shown, after the barrel foundation 1 is installed on the seabed 7, the interior of the barrel foundation 1 is composed of the seabed 7 and the seawater 8, that is, the lower part of the top cover of the barrel foundation 1 is not in effective contact with the seabed.

[0072] In this case, in order to make the barrel foundation 1 form a tight connection with the seabed and effectively ensure the stability of the offshore wind turbine operation, the grouting module 4 can be used to pour grouting material into the barrel foundation 1 to fill the space below the top cover of the barrel foundation 1.

[0073] However, if Figure 2 As shown, the seabed surface inside the barrel foundation 1 is actually uneven, and grouting uniformity cannot be guaranteed by only using the grouting module 4 for grouting.

[0074] Therefore, in the embodiment of the present application, on the basis of setting the grouting module 4, a first sensor module 5 is also arranged at the lower part of the top cover of the barrel foundation 1, and the first sensor module 5 includes a plurality of first sensors, and the plurality of first sensors are used to collect the first temperature information of the upper end of the barrel foundation 1. When the grouting operation is performed, the plurality of first sensors collect the plurality of first temperature information in real time, and send the plurality of first temperature information to the monitoring module 6, so that the monitoring module 6 can determine the grouting condition in the barrel foundation 1 according to the plurality of first temperature information.

[0075] This is because the temperature of the grouting material is different from the temperature of seawater. When the lower part of the top cover of the barrel foundation 1 does not contact the grouting material, the temperature values ​​corresponding to the first temperature information collected by multiple first sensors are all the temperature of seawater; when only a partial area of ​​the lower part of the top cover of the barrel foundation 1 contacts the grouting material, the temperature value corresponding to the first temperature information collected by the first sensor located in this area is the temperature of the grouting material, and the temperature value corresponding to the first temperature information collected by the first sensor located in the remaining area is the temperature of seawater; when the lower part of the top cover of the barrel foundation 1 is completely in contact with the grouting material, the temperature values ​​corresponding to the first temperature information collected by multiple first sensors are all the temperature of the grouting material.

[0076] Therefore, the monitoring module 6 can determine the position of the grouting material in the barrel foundation 1 based on multiple first temperature information, judge whether the lower part of the top cover of the barrel foundation 1 is in complete contact with the grouting material, and when it is determined that the lower part of the top cover of the barrel foundation 1 is in complete contact with the grouting material, send a closing signal to the grouting module 4 to drive the grouting module 4 to close, so as to stop the grouting operation.

[0077] Specifically, after acquiring a plurality of first temperature information, the monitoring module 6 determines whether the temperature values ​​corresponding to the plurality of first temperature information are all in the first temperature range and are consistent, that is, determines whether the temperature values ​​corresponding to the plurality of first temperature information are the temperatures of the grouting material. After determining that the temperature values ​​corresponding to the plurality of first temperature information are all the temperatures of the grouting material, a closing signal is sent to the grouting module 4 to drive the grouting module 4 to close, and the grouting operation is completed. The grouting condition in the barrel foundation 1 after the grouting operation is completed can be referred to Figure 3 , Figure 3 FIG. 4 shows a rear cross-sectional view of a barrel-type foundation grouting quality monitoring system according to an embodiment of the present application, as shown in FIG. Figure 3 As shown, the grouting material 10 is evenly distributed between the top cover of the barrel foundation 1 and the seabed 7 , and the lower part of the top cover of the barrel foundation 1 is in complete contact with the grouting material 10 .

[0078] Therefore, the embodiment of the present application sets multiple first sensors at the lower part of the top cover of the barrel foundation 1 to collect the first temperature information of the upper end of the barrel foundation 1 in real time, and sends the first temperature information to the monitoring module 6 in real time, so that the monitoring module 6 can monitor the grouting condition in the barrel foundation 1 in real time according to the first temperature information. After the temperature values ​​corresponding to the multiple first temperature information reach the temperature of the grouting material, the grouting module 4 is driven to close, and the grouting operation is completed, thereby realizing the monitoring of the grouting condition inside the barrel foundation 1, so that even if the surface of the seabed 7 is uneven, the grouting material in the barrel foundation 1 can still be ensured to be evenly distributed, which is beneficial to the stability of the operation of the offshore wind turbine.

[0079] In an optional embodiment, referring to Figure 4 , Figure 4A schematic diagram of the arrangement of a first sensor module according to an embodiment of the present application is shown. Figure 4 As shown, the first sensor module 5 includes two first sensors 51 , and the two first sensors 51 are cross-arranged at the lower part of the top cover of the barrel foundation 1 .

[0080] In the embodiment of the present application, in order to further save costs, the first sensor module 5 may include two first sensors 51 , and the two first sensors 51 are cross-arranged at the lower part of the top cover of the barrel foundation 1 .

[0081] In this way, while reducing costs, comprehensive monitoring of the temperature at the upper end of the barrel foundation 1 can be ensured, ensuring that the monitoring module 6 can accurately monitor the grouting condition in the barrel foundation 1 in real time based on the first temperature information collected by the first sensor 51.

[0082] In an optional embodiment, if Figure 2 As shown, the grouting module 4 includes a grouting pump 41 and a grouting pipe 42 connecting the grouting pump 41 and the barrel foundation 1;

[0083] Wherein, a control valve is installed in the grouting pipeline 42, and the control valve is connected to the monitoring module 6, and is used to adjust the flow rate of the grouting material input into the barrel foundation 1 by the grouting pump 41;

[0084] The monitoring module 6 is further configured to send the closing signal to the control valve to drive the control valve to close when it is determined that the plurality of first temperature information are all within the first temperature range and are consistent.

[0085] The grouting pump 41 is used to pump the grouting material 10 into the grouting pipe 42 , so that the grouting material 10 can be input into the barrel foundation 1 through the grouting pipe 42 .

[0086] Among them, a control valve is also installed in the slurry pipe 42, which is connected to the monitoring module 6 and is used to adjust the flow rate of grouting material input into the barrel foundation 1 by the grouting pump 41. In this way, the monitoring module 6 can send a closing signal to the control valve when it is determined that multiple first temperature information are all in the first temperature range and consistent. The control valve performs a closing operation in response to the closing signal to stop the input of the grouting material 10.

[0087] In an optional embodiment, if Figure 2 As shown, the grouting pipes 42 include a plurality of grouting pipes 42 , and the plurality of grouting pipes 42 are evenly arranged on the outer edge of the top cover of the barrel foundation 1 .

[0088] In the embodiment of the present application, a plurality of grouting pipes 42 are included, and the plurality of grouting pipes 42 are evenly arranged on the outer edge of the top cover of the barrel foundation 1. In this way, the grouting pump 41 can input grouting material into the barrel foundation 1 through the plurality of grouting pipes 42 to improve the grouting efficiency.

[0089] In an optional embodiment, if Figure 2 As shown, the monitoring system also includes:

[0090] The second sensor module 9, wherein reference Figure 5 , Figure 5 FIG. 4 shows a front cross-sectional view of another barrel-type foundation grouting quality monitoring system according to an embodiment of the present application, as shown in FIG. Figure 5 As shown, the second sensor module 9 includes a plurality of second sensors 91, and the plurality of second sensors 91 correspond to the plurality of grouting pipes 42 one by one, and are all arranged on the inner wall of the barrel foundation 1 close to the respective corresponding grouting pipes 42, and the second sensors 91 are used to collect the second temperature information inside the barrel foundation 1;

[0091] The monitoring module 6 is connected to the plurality of second sensors 91 respectively, and is used to obtain the second temperature information collected by the second sensor 91, and send a flow signal to the control valve in the grouting pipeline 42 corresponding to the second sensor 91 in response to the second temperature information, so as to drive the control valve to operate at the target opening;

[0092] Wherein, when the temperature value corresponding to the second temperature information is within the first temperature interval, the target opening is the first target opening; when the temperature value corresponding to the second temperature information is within the second temperature interval, the target opening is the second target opening;

[0093] The second temperature range represents the temperature of seawater in the sea area where the barrel foundation 1 is located; and the first target opening is smaller than the second target opening.

[0094] In actual situations, when the surface of the seabed 7 is uneven, the bottom of the top cover of the barrel foundation 1 is easy to contact a certain high point on the surface of the seabed 7, so that the surface of the seabed 7 and the space inside the barrel foundation 1 are separated into multiple spaces. In the embodiment of the present application, multiple grouting pipes 42 are arranged above the top cover of the barrel foundation 1, which means that when the grouting operation is performed, some spaces inside the barrel foundation 1 will be quickly filled with grouting material 10, while the filling progress of the grouting material 10 in another part of the space is relatively slow, resulting in that when some spaces are filled with grouting material 10, because there is still another part of the space that has not been filled, the grouting pipe 42 above the part of the space that has been filled with grouting material 10 continues to input grouting material 10 into the part of the space, resulting in an increase in the amount of grouting material used.

[0095] In view of the above situation, the embodiment of the present application further provides a second sensor module 9 in the monitoring system, and the second sensor module 9 includes a plurality of second sensors 91, and the plurality of second sensors 91 correspond to the plurality of grouting pipes 42 one by one, and are all provided on the inner wall of the barrel foundation 1 close to the respective corresponding grouting pipes 42, for collecting the second temperature information inside the barrel foundation 1. In this way, the second sensor 91 can collect the temperature information of the internal space of the barrel foundation 1 below the corresponding grouting pipe 42, that is, the second temperature information, in real time.

[0096] In this way, after acquiring the second temperature information collected by the second sensor 91 , the monitoring module 6 can determine whether the grouting material 10 has submerged the second sensor 91 according to the second temperature information.

[0097] Specifically, when the temperature value corresponding to the second temperature information is in the first temperature range, it indicates that the grouting material 10 is submerged in the second sensor 91; when the temperature value corresponding to the second temperature information is in the second temperature range, the second temperature range represents the temperature of the seawater in the sea area where the barrel foundation 1 is located, which indicates that the grouting material 10 is not submerged in the second sensor 91.

[0098] In this way, the monitoring module 6 can send a flow signal to the control valve in the grouting pipe 42 corresponding to the second sensor 91 based on the second temperature information collected by the second sensor 91, drive the control valve to operate at the target opening, and reasonably regulate the use of the grouting material 10 to avoid excessive use of the grouting material.

[0099] Specifically, when the monitoring module 6 determines that the temperature value corresponding to the second temperature information collected by the second sensor 91 is in the first temperature interval, the first flow signal is sent to the control valve in the grouting pipe 42 corresponding to the second sensor 91, and the control valve is driven to operate at the first target opening; when the monitoring module 6 determines that the temperature value corresponding to the second temperature information collected by the second sensor 91 is in the second temperature interval, the second flow signal is sent to the control valve in the grouting pipe 42 corresponding to the second sensor 91, and the control valve is driven to operate at the second target opening. In other words, when the grouting material 10 does not pass through the second sensor 91, the opening of the control valve in the grouting pipe 42 corresponding to the second sensor 91 is the second target opening, and when the grouting material 10 does not pass through the second sensor 91, the opening of the control valve in the grouting pipe 42 corresponding to the second sensor 91 is the first target opening.

[0100] The first target opening is smaller than the second target opening.

[0101] Therefore, after determining that the grouting material 10 has not passed the second sensor 91 , the opening of the control valve in the grouting pipe 42 corresponding to the second sensor 91 is reduced, and the second target opening is adjusted to the first target opening to reduce the input of the grouting material 10 .

[0102] When the temperature values ​​corresponding to the multiple first temperature information acquired by the monitoring module 6 are all in the first temperature range and consistent, a closing signal is sent to the control valves in each grouting pipeline 42 to drive the control valves to close, thereby completing the grouting operation.

[0103] Therefore, the embodiment of the present application combines the second temperature information collected by the second sensor 91 to further monitor the grouting conditions of each space inside the barrel foundation 1, thereby adjusting the opening of the control valve in each grouting pipe 42, realizing the reasonable distribution and use of the grouting material 10, and avoiding the waste caused by excessive use of the grouting material.

[0104] In an optional implementation, the control valve is an electric valve.

[0105] In the embodiment of the present application, the electric valve has the advantages of easy operation, quick response, precise control, etc., and can meet the flow control requirements of the grouting material 10.

[0106] In an optional implementation, the vertical distance between the second sensor 91 and the top cover of the barrel foundation 1 is 0 to 500 mm.

[0107] In the embodiment of the present application, in order to ensure that the second sensor 91 can collect the temperature of the seawater and the temperature of the grouting material 10, the vertical distance between the second sensor 91 and the top cover of the barrel foundation 1 is set to 0 to 500 mm.

[0108] Among them, when the vertical distance between the second sensor 91 and the top cover of the barrel foundation 1 is smaller, the first target opening is smaller, and the minimum is zero.

[0109] In an optional embodiment, the second sensor 91 is fixed to the inner wall of the barrel foundation 1 by bonding.

[0110] In an optional implementation, both the first sensor 51 and the second sensor 91 are temperature sensors.

[0111] In an optional embodiment, if Figure 2 As shown, the first sensor 51 and the second sensor 91 are both connected to the monitoring module 6 via a signal line 11 .

[0112] In specific implementation, the monitoring module 6 and the control valve may also be connected via a signal line 11 .

[0113] In an optional embodiment, if Figure 2 As shown, the grouting pipeline 42 includes a first pipeline 421 disposed on the top cover of the barrel foundation 1, and a second pipeline 422 connected to the grouting pump 41;

[0114] The second pipe 422 is also detachably connected to the first pipe 421 .

[0115] In the embodiment of the present application, the grouting pipe 42 includes a first pipe 421 arranged on the top cover of the barrel foundation 1, and a second pipe 422 connected to the grouting pump 41, and the second pipe 422 is detachably connected to the first pipe 421.
