Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the utility model and are not to be construed as limiting the utility model.
As shown in fig. 1 to 5, the offshore wind power reinforcing apparatus according to the embodiment of the present invention includes a suction tube 2, a column 1, and a duct 3.
The suction cylinder 2 is buried in the seabed, the top end face 22 of the suction cylinder is exposed out of the seabed, and the bottom of the upright column 1 is connected with the suction cylinder 2;
specifically, the suction tube 2 is a hollow-shaped cylinder whose lower end is open, the suction tube 2 includes a side wall 21 and a top end face 22, the lower end of the side wall 21 extends into the sea bed, and the upper end and the top end face 22 of the side wall 21 are higher than the surface of the sea bed. The column 1 extends in the up-down direction, and the lower end of the column 1 is connected to the center of the top end face 22.
A portion of the guide tube 3 is inserted downward into the seabed through the top of the suction tube 2, a portion of the guide tube 3 above the suction tube 2 is provided with a grout port 31, a portion of the guide tube 3 inserted into the seabed is provided with a grout port 32, and the guide tube 3 is used to inject seabed reinforcing material into the seabed to reinforce the seabed in the vicinity of the pile foundation 23.
Specifically, the pile foundation 23 is a cylinder extending in the up-down direction, and the axis of the pile foundation 23 coincides with the axis of the suction tube 2, that is, the pile foundation 23 is located at the center of the suction tube 2. The guide tube 3 is a hollow structure, the guide tube 3 extends in the up-down direction, the guide tube 3 penetrates the top end surface 22, namely, the upper end of the guide tube 3 is higher than the top end surface 22, and the lower end of the guide tube 3 is lower than the top end surface 22. The grout port 31 is provided on the upper side of the tip end face 22, the grout port 32 is provided on the lower side of the tip end face 22, and the grout port 31 and the grout port 32 communicate with each other. Thereby, the seabed reinforcing material poured from the grout port 31 can flow into the suction cylinder 2 from the grout port 32.
In some embodiments, the plurality of injection ports 32 of the guide duct 3 are provided, and at least a part of the injection ports 32 are arranged at intervals along the length direction of the guide duct 3.
Specifically, the guide pipe 3 is a circular pipe extending in the up-down direction, and the length direction of the guide pipe 3 is the vertical up-down direction, that is, at least a part of the grouting ports 32 are arranged at intervals in the vertical up-down direction. Thereby, a plurality of injection openings 32 may on the one hand increase the flow of seabed reinforcing material out of the conduit 3, and on the other hand the evenly arranged injection openings 32 may provide a more even flow of seabed reinforcing material into the seabed.
In some embodiments, the conduit 3 is multiple, with multiple conduits 3 spaced around the pile foundation 23.
Specifically, the plurality of guide pipes 3 are arranged at intervals circumferentially around the pile foundation 23, and the intervals between two adjacent guide pipes 3 in the circumferential direction are all equal. Thereby, the seabed reinforcing material can flow more uniformly into the seabed around the pile foundation 23.
In some embodiments, a portion of the plurality of ducts 3 are spaced radially of the suction cartridge 2.
Specifically, a part of the plurality of guide tubes 3 is arranged at intervals in the radial direction, and two guide tubes 3 are arranged in the radial direction of the suction tube 2. Thus, when injecting the seabed reinforcing material around the pile foundation 23, it is possible to separately inject the seabed reinforcing material to different positions, which increases the efficiency of injecting the seabed reinforcing material.
In some embodiments, the plurality of ducts 3 are divided into groups, each group of ducts 3 includes a plurality of ducts 3 therein, the plurality of ducts 3 in each group of ducts 3 are spaced apart along the circumference of the pile foundation 23, and the plurality of groups of ducts 3 are spaced apart in the radial direction of the suction tube 2.
Specifically, the plurality of tubes 3 are divided into an inner layer group including a part of the tubes 3 and an outer layer group including another part of the tubes 3. The conduits 3 of the inner layer group and the conduits 3 of the outer layer group are respectively arranged around the circumference of the pile foundation 23 at equal intervals. The conduits 3 of the inner layer group and the conduits 3 of the outer layer group are in one-to-one correspondence, the conduits 3 of the inner layer group and the conduits 3 of the outer layer group corresponding to the inner layer group are arranged along the radial direction, and the distance between each conduit 3 of the inner layer group and the conduit 3 of the outer layer group corresponding to the inner layer group is equal. Thereby, the seabed reinforcing material can flow more uniformly into the seabed around the pile foundation 23.
In some embodiments, the ends of the conduits 3 of each set of conduits 3 that extend into the seabed are all located on the same horizontal plane and are spaced circumferentially of the pile foundation 23.
Specifically, the heights of the lower ends of the tubes 3 of the inner group are all the same, and the tubes 3 of the inner group are all arranged at equal intervals in the circumferential direction of the pile foundation 23. The lower ends of the tubes 3 of the outer group are all the same in height, and the tubes 3 of the outer group are all arranged at equal intervals along the circumferential direction of the pile foundation 23. The height of the lower ends of the tubes 3 of the inner group may be the same as or different from the height of the lower ends of the tubes 3 of the outer group.
In some embodiments, several sets of conduits 3 correspond to a plurality of levels having different relative heights.
It should be noted that, by injecting seabed reinforcing materials with different depths into different positions, different positions in the reinforced area have different mechanical properties.
In some embodiments, of the plurality of conduits 3 spaced radially of the suction tube 2, a portion of the conduits 3 remote from the upright 1 is buried into the seabed to a greater depth than another portion of the conduits 3 adjacent to the upright 1.
Specifically, the lower ends of the tubes 3 of the outer series are lower in height than the lower ends of the tubes 3 of the inner series. Thus, after the seabed around the pile foundation 23 is solidified, the soil mass on the outer side becomes more rigid.
According to the offshore wind power foundation reinforcing method provided by the embodiment of the utility model, the reinforcing method is reinforced by using the reinforcing device of any one embodiment, and the reinforcing method comprises the following steps:
step 1: the top of the suction cylinder 2 is provided with an opening, and a guide pipe 3 penetrates through the top of the suction cylinder 2 from the top of the suction cylinder 2 through the opening from top to bottom and is inserted into the seabed;
specifically, the through hole above the suction tube 2 is a circular hole extending in the up-down direction and circumferentially arranged at equal intervals on the top end surface 22. The trompil divide into inlayer and skin, the trompil of inlayer and the trompil one-to-one of skin, and the distance between the trompil of every inlayer and its corresponding trompil is all the same. The lower end of the inner layer of the guide tube 3 is higher than the lower end of the outer layer of the guide tube 3 in inserting the guide tube 3.
Step 2: grout is injected into the seabed through the pipe 3 to reinforce the seabed.
Specifically, cement slurry, which is a seabed reinforcing material, is added to the guide pipes 3 from the grout ports 31 at the upper ends of all the guide pipes 3.
In some embodiments, the reinforcement method further comprises:
and step 3: after the cement slurry is injected, injecting air or water into the guide pipe 3 to clean the inner channel of the guide pipe 3;
specifically, air or water is supplied into the duct 3 from the grout port 31 at the upper end of all the ducts 3, so that the grout remaining in the duct 3 can be flushed out of the duct 3 through the grout port 32, thus preventing the grout from being solidified in the duct 3 to clog the duct 3.
And 4, step 4: and (5) repeating the step (2) when the seabed is softened.
In particular, step 2 is repeated until the seabed around the pile foundation 23 reaches the required mechanical conditions.
