[0002] The flow condition around the wind turbine foundation in the offshore wind farm is very complex. On the one hand, the wind turbine foundation will change the distribution of the flow field around the wind turbine foundation, causing local scour of the surrounding seabed soil and forming a scour pit. On the other hand, the natural erosion and deposition exist in part of the seabed. The coupling of local scour and natural scour poses a higher challenge to scour prevention and control.

In order to solve the above problems, the embodiment of the present application provides a cementing material construction device in a complex wave flow environment.

[0043] Referring to Figures 1 to 5 The embodiment of the present application provides a cementing material construction device in a complex wave flow environment, which comprises: a pouring pipe 1 used for pouring of cementing material 11, a discharge port 101 is arranged at the bottom of the pouring pipe 1; a first liquid injection pipe 2 connected to the pouring pipe 1 and communicating with the pouring pipe 1, the first liquid injection pipe 2 is used for injecting a first protective agent into the pouring pipe 1; a protective agent diffusion assembly connected to the pouring pipe 1, the protective agent diffusion assembly is used for injecting a second protective agent and spraying the second protective agent to form a protection area 12, the protection area 12 is located below the periphery of the discharge port 101; a flow slowing device arranged in the pouring pipe 1, the flow slowing device is used for slowing down the downward flow speed of the cementing material 11 under the action of gravity.

[0044] Specifically, the pouring pipe 1 has an inner hole penetrating along the length direction thereof, and the cross section of the pouring pipe 1 can be circular ring shape. The cementing material 11 can be poured to the construction area through the discharge port 101 at the bottom of the pouring pipe 1.

The concentration of the second protective agent is preferably greater than that of the first protective agent. The concentration of the second protective agent can be 1%-5%, and the concentration of the first protective agent can be 1‰-5‰.

[0046] During construction, the cementing material 11 is injected into the pouring pipe 1, the first protective agent is injected into the first liquid injection pipe 2, and the second protective agent is injected into the protective agent diffusion assembly. The first protective agent is injected into the pouring pipe 1 through the first liquid injection pipe 2, the cementing material 11 is poured to the construction area through the discharge port 101 of the pouring pipe 1, at the same time, the protective agent diffusion assembly sprays the second protective agent to form the protection area 12 below the periphery of the discharge port 101, and the cementing material 11 flows out of the discharge port 101 and enters the protection area 12.

[0047] In the embodiment of the present application, the first liquid injection pipe 2 can inject the first protective agent into the pouring pipe 1, so that the water washing and segregation of the cementing material 11 during the downward flow in the pouring pipe 1 can be avoided, the protective agent diffusion assembly can spray the second protective agent to form the protection area 12, and the cementing material 11 flows out of the pouring pipe 1 and enters the protection area 12, so that the dispersion or segregation of the cementing material 11 is avoided, and the pouring quality is ensured. In addition, the flow slowing device is arranged in the pouring pipe 1 to slow down the flow speed of the cementing material 11, so that the flow speed of the cementing material 11 flowing out of the discharge port 101 is reduced, and the failure of the cementing material 11 caused by the high-speed impact of the cementing material on the surface of the rock accumulation body is avoided.

[0048] With reference to Figure 1 and Figure 2 In a preferred embodiment of the present application, the protective agent diffusion assembly comprises a second liquid injection pipe 3, an annular connecting pipe 4 and at least one diffusion pipe 5. The second liquid injection pipe 3 is used for injecting the second protective agent, and the at least one diffusion pipe 5 is used for spraying the second protective agent. The bottom of the second liquid injection pipe 3 is in communication with the annular connecting pipe 4, the annular connecting pipe 4 is connected to the bottom of the pouring pipe 1, and the at least one diffusion pipe 5 is in communication with the annular connecting pipe 4.

[0049] Specifically, the second liquid injection pipe 3 can be bonded to the pouring pipe 1. The length of the first liquid injection pipe 2 is less than the length of the second liquid injection pipe 3. The bottom of the second liquid injection pipe 3 is in communication with the annular connecting pipe 4, so that the second protective agent injected into the second liquid injection pipe 3 can flow into the annular connecting pipe 4. The annular connecting pipe 4 is in communication with the diffusion pipe 5, so that the second protective agent in the annular connecting pipe 4 can flow into the diffusion pipe 5. The diffusion pipe 5 is used for spraying the second protective agent, so that the second protective agent is dispersed in the peripheral water of the pouring pipe 1 to form the protection area 12. During construction, the second protective agent is injected into the second liquid injection pipe 3, the second protective agent in the second liquid injection pipe 3 flows to the annular connecting pipe 4, and then flows to each diffusion pipe 5 through the annular connecting pipe 4. Each diffusion pipe 5 sprays the second protective agent to form the protection area 12 around the discharge port 101.

[0050] With reference to Figure 1 and Figure 3 In a preferred embodiment of the present application, the flow slowing device comprises at least one annular protrusion 6. The annular protrusion 6 is arranged on the inner wall of the pouring pipe 1. The inner diameter of the annular protrusion 6 is less than the inner diameter of the pouring pipe 1, and greater than or equal to one half of the inner diameter of the pouring pipe 1. The number of the annular protrusions 6 can be one or more, and the number of the annular protrusions 6 is preferably more. The material of the annular protrusion 6 is preferably an elastic material, such as rubber. The bottom of the first liquid injection pipe 2 is preferably higher than the uppermost annular protrusion 6.

[0051] With reference to Figure 1 and Figure 3 In a preferred embodiment of the present application, the slow flow device further comprises an elastic ball 7, the elastic ball 7 having a natural state and an elastically deformed state, the elastic ball 7 in the natural state having an outer diameter smaller than the inner diameter of the pouring pipe 1 and larger than the inner diameter of the annular protrusion 6; the annular protrusion 6 is used to block the elastic ball 7 in the natural state; the elastic ball 7 is used to be elastically deformed under the action of a downward force, and the elastic ball 7 in the elastically deformed state is used to pass through the annular protrusion 6.

[0052] Specifically, the downward direction can refer to the direction shown by the A arrow in Figure 1 . The natural state is the state of the elastic ball 7 without force, and the elastic ball 7 in the natural state is a regular spherical body. The shape of the elastic ball 7 changes after it is elastically deformed. The elastic ball 7 can be elastically deformed under the action of a downward force so as to be able to pass through the annular protrusion 6, and the elastic ball 7 restores its original shape after passing through the annular protrusion 6. The material of the elastic ball 7 can be rubber. The number of the annular protrusions 6 is preferably three. Before pouring the cementitious material 11 into the pouring pipe 1, the elastic ball 7 needs to be placed into the pouring pipe 1 first, and after the elastic ball 7 is placed, the elastic ball 7 is in contact with the uppermost annular protrusion 6. After the cementitious material 11 is injected into the pouring pipe 1, the elastic ball 7 is elastically deformed under the action of the gravity of the cementitious material 11, and the elastic ball 7 is in the elastically deformed state, and the elastic ball 7 in the elastically deformed state passes through the uppermost annular protrusion 6, and the cementitious material 11 flows downward, and then the elastic ball 7 passes through each annular protrusion 6 in turn until it flows out from the discharge port 101.

[0053] The material of the annular protrusion 6 is an elastic material, such as rubber. Through the cooperation between the elastic ball 7 and the annular protrusion 6, the cementitious material 11 poured into the pouring pipe 1 can flow downward together, and at the same time, the elastic deformation of the elastic ball 7 and the annular protrusion 6 can reduce the speed of the cementitious material 11 flowing downward, so as to avoid the failure caused by the high-speed impact of the cementitious material on the surface of the rock accumulation body when the cementitious material flows out from the discharge port of the pouring pipe at a high speed.

[0054] Preferably, the elastic ball 7 is hollow inside. The wall thickness of the elastic ball 7 can be set according to actual needs, and the present embodiment does not limit this. When the elastic ball 7 is hollow inside, the weight of the elastic ball 7 is lighter, and it is beneficial to the elastic deformation of the elastic ball 7.

[0055] With reference to Figure 2 and Figure 5In a preferred embodiment of the present application, the number of diffusion pipes 5 is at least two, the shape of the discharge port 101 is circular, and the at least two diffusion pipes 5 are arranged along the circumference of the discharge port 101; the at least two diffusion pipes 5 are evenly arranged along the circumference of the discharge port 101, and the at least two diffusion pipes 5 are arranged along the entire circumference of the circumference of the discharge port 101, or the at least two diffusion pipes 5 are arranged along half of the circumference of the circumference of the discharge port 101, and the at least two diffusion pipes 5 are arranged on the upstream side of the unidirectional flow in the complex wave flow environment.

[0056] The number of diffusion pipes 5 can be three, four, five, six, eight, ten, etc. The at least two diffusion pipes 5 are arranged around the discharge port 101. The at least two diffusion pipes 5 are preferably evenly arranged along the circumference of the discharge port 101. For reciprocating flow, the at least two diffusion pipes 5 are distributed around the pouring pipe 1, and the at least two diffusion pipes 5 are arranged along the entire circumference of the circumference of the discharge port 101. For unidirectional flow, the at least two diffusion pipes 5 can be distributed on only one side of the pouring pipe 1, that is, the at least two diffusion pipes 5 can be arranged along only half of the circumference of the circumference of the discharge port 101, and the at least two diffusion pipes 5 are arranged on the upstream side of the unidirectional flow.

[0057] Referring to Figure 1 , Figure 3 and Figure 4 , in a preferred embodiment of the present application, the at least one diffusion pipe 5 is rotatably connected to the annular connecting pipe 4, and the diffusion pipe 5 has an unfolded state and a retracted state; when the diffusion pipe 5 is in the unfolded state, the included angle between the diffusion pipe 5 and the outer wall of the pouring pipe 1 is greater than 90 degrees and less than 180 degrees, and when the at least one diffusion pipe 5 is in the unfolded state, a protection area 12 is formed below the pouring pipe 1; when the diffusion pipe 5 is in the retracted state, the included angle between the diffusion pipe 5 and the outer wall of the pouring pipe 1 is less than 45 degrees.

[0058] The included angle between the diffusion pipe 5 and the outer wall of the pouring pipe 1 can refer to α shown in Figure 3 . When the diffusion pipe 5 is in the retracted state, the included angle between the diffusion pipe 5 and the outer wall of the pouring pipe 1 is preferably less than 15 degrees. During transportation of the cementitious material construction device in the complex wave flow environment, the diffusion pipe 5 can be in the retracted state to reduce the space occupied during transportation, facilitating transportation of the cementitious material construction device in the complex wave flow environment. During pouring construction, the diffusion pipe 5 is unfolded so that the diffusion pipe 5 is in the unfolded state. In addition, when the diffusion pipe 5 is installed, the diffusion pipe 5 can be in the retracted state to improve the convenience of installation.

[0059] Referring to Figure 5 , in a preferred embodiment of the present application, the cementitious material construction device in the complex wave flow environment further comprises a water pipe 8 connected to the pouring pipe 1, the water pipe 8 is in communication with the at least one diffusion pipe 5, and the water pipe 8 is used for injecting high-pressure water.

[0060] Specifically, the water pipe 8 is preferably in communication with the annular connecting pipe 4, and the water pipe 8 is in communication with the diffusion pipe 5 through the annular connecting pipe 4. High-pressure water is poured into the water pipe 8, and the high-pressure water flows into the diffusion pipe 5 through the water pipe 8 and flows out of the diffusion pipe 5 with the second protective agent. In the embodiment of the present application, the pouring of high-pressure water into the water pipe 8 improves the diffusion speed of the second protective agent, and the high-pressure water is also beneficial to improving the diffusion range of the cementing material, so as to improve the accuracy of the landing point of the cementing material on the surface of the gravel accumulation body.

[0061] With reference to Figure 1 and Figure 3 In a preferred embodiment of the present application, at least one diffusion pipe 5 is connected to the pouring pipe 1 through the first driving mechanism 9, and the first driving mechanism 9 is used to drive the diffusion pipe 5 to switch back and forth between the expanded state and the retracted state.

[0062] Specifically, the first driving mechanism 9 can be a first electric telescopic rod, and the expansion and retraction of the diffusion pipe 5 can be realized through the first electric telescopic rod. In addition, the angle of the included angle between the diffusion pipe 5 and the outer wall of the pouring pipe 1 when the diffusion pipe 5 is in the expanded state can also be adjusted through the first driving mechanism 9 to adapt to different complex water flow conditions.

[0063] With reference to Figure 3 In a preferred embodiment of the present application, the diffusion pipe 5 includes at least two diffusion segments 501, and adjacent two diffusion segments 501 are rotationally connected, and a second driving mechanism 10 is connected between the adjacent two diffusion segments 501, and the second driving mechanism 10 is used to adjust the angle of the included angle between the adjacent two diffusion segments 501.

[0064] Specifically, the number of diffusion segments 501 can be two, three, four, etc. The second driving mechanism 10 can be a second electric telescopic rod. After the angle of the included angle between the adjacent two diffusion segments 501 is adjusted to be larger through the second driving mechanism 10, the range of the protection area 12 is correspondingly enlarged. After the angle of the included angle between the adjacent two diffusion segments 501 is adjusted to be smaller through the second driving mechanism 10, the range of the protection area 12 is correspondingly reduced. In the embodiment of the present application, the angle of the included angle between the adjacent two diffusion segments 501 can be adjusted through the second driving mechanism 10, so as to enlarge or reduce the range of the protection area 12 according to the water flow condition and the pouring speed, so as to improve the protection effect.

[0065] In a preferred embodiment of the present application, the pouring pipe 1 is used to pour a first capacity of cementing material 11 at a time, and the gravity of the first capacity of cementing material 11 is greater than the sum of the buoyancy of the first capacity of cementing material 11, the buoyancy of the elastic ball 7 and the resistance of the annular protrusion 6 to the elastic ball 7.

[0066] Specifically, the material of the annular protrusion 6 is an elastic material, such as rubber. During the downward flow of the first volume of the cementitious material 11 in the pouring pipe 1, the gravity of the first volume of the cementitious material 11 causes the elastic ball 7 and the annular protrusion 6 to be elastically deformed, and the resistance generated by the elastic deformation between the annular protrusion 6 and the elastic ball 7 continuously reduces the flow rate of the cementitious material 11 from the discharge port 101 of the pouring pipe 1, while the elastic ball 7 and the annular protrusion 6 can also ensure that the cementitious material 11 is poured in a pipe shape.

[0067] In a preferred embodiment of the present application, a plurality of nozzles are arranged on each diffusion pipe 5, the nozzles being used to spray the second protective agent, and the plurality of nozzles are arranged at intervals along the length direction of the diffusion pipe 5. Specifically, the second protective agent is sprayed from the plurality of nozzles under the action of a pouring pressure, and the pouring pressure can be set according to the water flow intensity and the distance between the discharge port 101 of the pouring pipe 1 and the pouring surface. The number of nozzles on a single diffusion pipe 5 can be set according to actual needs, such as three, four, five, six, eight, ten, etc. Through the arrangement of the plurality of nozzles, the second protective agent can be sprayed from multiple places at the same time to ensure the protection effect of the cementitious material.

[0068] Referring to Figure 1 and Figure 3 In a preferred embodiment of the present application, the number of annular protrusions 6 is at least two, and the at least two annular protrusions 6 are arranged at intervals along the length direction of the pouring pipe 1. The number of annular protrusions 6 can be two, three, four, five, six, ten, etc. The at least two annular protrusions 6 can be arranged at unequal intervals along the length direction of the pouring pipe 1. In the downward direction, the distance between adjacent two annular protrusions 6 can gradually decrease. In the embodiment of the present application, the at least two annular protrusions 6 cooperate with the elastic ball 7 to form a multi-stage flow resistance effect.

[0069] The process of pouring the cementitious material by using the cementitious material construction device in the complex wave flow environment described above can include:

[0070] S1, first place the elastic ball 7 in the pouring pipe 1, and after the elastic ball 7 is placed, the elastic ball 7 is in contact with the uppermost annular protrusion 6;

[0071] S2, inject the cementitious material 11 into the pouring pipe 1, inject the first protective agent into the first liquid injection pipe 2, and inject the second protective agent into the second liquid injection pipe 3;

[0072] S3, the first protective agent is injected into the pouring pipe 1 through the first liquid injection pipe 2, the cementitious material 11 is poured into the construction area through the discharge port 101 of the pouring pipe 1, and the second protective agent in the second liquid injection pipe 3 flows into the annular connecting pipe 4 and then flows into each diffusion pipe 5 through the annular connecting pipe 4, each diffusion pipe 5 sprays the second protective agent to form a protective area 12 around the discharge port 101, and the cementitious material 11 flows out of the discharge port 101 and then enters the protective area 12.

[0073] It should be noted that the elastic ball 7 is elastically deformed under the action of the gravity of the cementitious material 11 during the flow of the cementitious material 11 in the pouring pipe 1, the elastic ball 7 is in an elastically deformed state, and the elastically deformed elastic ball 7 passes through the uppermost annular protrusion 6, and then the elastic ball 7 passes through each annular protrusion 6 in turn until it flows out of the discharge port 101.
