[0028] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0029] like Figure 1 As shown, the rock-embedded construction equipment provided by the present application includes a rock-embedded platform 1, which includes an upper platform 11, a lower platform 12 and a support system 13. The upper platform 11 and the lower platform 12 are spaced a certain distance apart, for example, 5 meters apart.

[0030] The support system 13 is supported between the upper platform 11 and the lower platform 12 and below the lower platform 12. The upper platform 11 is provided with a plurality of upper rock-embedded holes 111, and the lower platform 12 is provided with a plurality of lower rock-embedded holes 121. The upper rock-embedded holes 111 and the lower rock-embedded holes 121 are arranged one by one. In the figure, three upper rock-embedded holes 111 and three lower rock-embedded holes 121 are provided, and the three upper rock-embedded holes 111 and the three lower rock-embedded holes 121 are arranged in a triangle, respectively, and of course not limited to three.

[0031] A drilling station C is provided near each upper rock-embedded hole 111 on the upper platform 11. During construction, a drilling rig is provided on the drilling station C. Figure 3 and Figure 4 understand.

[0032] Since the upper platform 11 of the rock-embedded platform 1 in the present application is provided with a plurality of upper rock-embedded holes 111, and the lower platform 12 is provided with a plurality of lower rock-embedded holes 121, the upper rock-embedded holes 111 and the lower rock-embedded holes 121 are arranged one by one, and a drilling station C is provided near each upper rock-embedded hole 111 on the upper platform 11, so during construction, the casing 3 can be sunk through each group of rock-embedded holes (see Figure 7 ), and a drilling rig is set at each drilling station C, and different drilling rigs perform drilling operations in the corresponding casing 3 at the same time, so that multiple boreholes can be drilled simultaneously on a rock-embedded platform 1, thereby improving the construction efficiency of the offshore wind power foundation and shortening the construction period of the offshore wind power foundation.

[0033] Moreover, in the present application, the rock-embedded platform 1 is provided with an upper platform 11 and a lower platform 12, and there is a support system 13 between the upper platform 11 and the lower platform 12 and below the lower platform 12, so the load-bearing requirements of setting up a drilling rig at each drilling station C can be met.

[0034] More specifically, after the drilling and cleaning of the borehole, the prefabricated pile 4 (see Figure 7) is implanted into the borehole, and then the bottom sealing concrete is poured, and then the outer wall of the precast pile 4 is backfilled with grout, and then the concrete is poured inside the precast pile 4, and finally the casing 3 is cut, and then the rock-embedded platform 1 can be moved to the next target position as needed.

[0035] In one embodiment, Figure 1 As shown, the support system 13 includes a plurality of columns 131. In the figure, the support system 13 is provided with four columns 131, and the four columns 131 are arranged in a rectangular shape, but are of course not limited to four. The upper ends of the columns 131 are connected to the upper platform 11 and the lower platform 12. The support system 13 also includes an integral anti-sinking seat 132, which is an integral structure, and the integral anti-sinking seat 132 is connected to the lower end of each column 131 at the same time. After the rock-embedded platform 1 is erected, the integral anti-sinking seat 132 contacts the seabed soil, so that the weight of the rock-embedded platform 1 itself is evenly pressed on the seabed, so that the stability is better, and the rock-embedded platform 1 and the structure on the rock-embedded platform 1 can be transferred as a whole.

[0036] In one embodiment, the rock-embedded construction equipment includes a floating crane 2 (see Figure 8 ), the floating crane 2 is used to transfer the rock-embedded platform 1 and the structure on the rock-embedded platform 1 as a whole. During the transfer, the structure on the rock-embedded platform 1 is reinforced without barging the structure on the rock-embedded platform 1 to the barge. Therefore, the construction efficiency of the offshore wind power foundation can be further improved and the construction period of the offshore wind power foundation can be shortened. More specifically, Figure 7 As shown, when the prefabricated piles 4 and the casing 3 are implanted, the prefabricated piles 4 and the casing 3 can also be hoisted by the floating crane 2 .

[0037] In one embodiment, Figure 1 As shown, the integrated anti-sinking seat 132 includes an anti-sinking grid frame E and an anti-sinking plate F laid on the anti-sinking grid frame E. Figure 6 As shown, the anti-sinking grid E includes a plurality of longitudinal anti-sinking main beams E1 and a plurality of transverse anti-sinking main beams E2, each longitudinal anti-sinking main beam E1 and each transverse anti-sinking main beam E2 are arranged crosswise to enclose an anti-sinking main frame. In the figure, there are two longitudinal anti-sinking main beams E1 and two transverse anti-sinking main beams E2, but it is not limited to two. The lower end of the column 131 is connected to the intersection of the longitudinal anti-sinking main beam E1 and the transverse anti-sinking main beam E2, and the longitudinal anti-sinking main beam E1 and the transverse anti-sinking main beam E2 share the vertical load transmitted by the column 131, so that the stability of the entire rock-embedded platform 1 is better.

[0038] In one embodiment, Figure 6As shown, the anti-sinking grid E also includes a plurality of anti-sinking auxiliary beams E3, and the cross-sectional area of ​​the anti-sinking auxiliary beams E3 is smaller than the cross-sectional area of ​​the anti-sinking main beam. In the figure, the anti-sinking auxiliary beams E3 are densely distributed on the anti-sinking main frame in the longitudinal and transverse directions, so that the anti-sinking grid E has a grid structure. This arrangement can further improve the bearing capacity of the integral anti-sinking seat 132.

[0039] In one embodiment, Figure 6 As shown, the integral anti-sinking seat 132 has an inner concave notch G at its edge and a central through hole H at its center, so that when the rock-embedded platform 1 is transferred, the integral anti-sinking seat 132 can be easily pulled up from the seabed under the action of the lifting force.

[0040] In one embodiment, Figure 3 and Figure 5 As shown, the upper platform 11 and the lower platform 12 both include a platform grid A and a platform plate B laid on the platform grid A. The platform grid A includes a plurality of longitudinal platform main beams A1 (two in the figure, but not limited to two) and a plurality of transverse platform main beams (two in the figure, but not limited to two). Each longitudinal platform main beam A1 and each transverse platform main beam A2 are arranged crosswise to enclose a platform main frame. The upper end of the column 131 is connected to the intersection of the longitudinal platform main beam A1 and the transverse platform main beam A2. The vertical load transmitted from the column 131 is shared by the longitudinal platform main beam A1 and the transverse platform main beam A2, so that the stability of the entire rock-embedded platform 1 is better.

[0041] In one embodiment, Figure 3 As shown, the inner area of ​​the platform frame of the upper platform 11 is used as a hoisting station D. During construction, a hoisting facility ( Figure 4 The lifting facility is a crane. Figure 3 and Figure 5 As shown, the upper rock-embedded holes 111 and the lower rock-embedded holes 121 are both located outside the inner area of ​​the platform main frame of the corresponding layer, so that the inner area of ​​the platform main frame has a higher bearing capacity and can stably bear heavier lifting facilities.

[0042] In one embodiment, Figure 3 As shown, the platform grid A also includes a plurality of platform auxiliary beams A3, and the cross-sectional area of ​​the platform auxiliary beams A3 is smaller than the cross-sectional area of ​​the platform main beam. In the figure, the platform auxiliary beams A3 are densely distributed on the platform main frame in the longitudinal and transverse directions, so that the platform grid A presents a grid structure, which can further improve the bearing capacity of the integral platform.

[0043] In one embodiment, the area of ​​the lower platform 12 is smaller than the area of ​​the upper platform 11, for example Figure 5In the figure, two convex areas 122 and two concave areas 123 are respectively arranged on the lateral sides of the lower platform 12, and a lower rock-embedded hole 121 is respectively arranged on the two convex areas 122. The two concave areas 123 make the area of ​​the lower platform 12 smaller than the area of ​​the upper platform 11. In this way, the space requirement of the upper platform 11 can be guaranteed, and the overall weight of the rock-embedded platform 1 can be guaranteed to be relatively light.

[0044] In one embodiment, Figure 1 As shown, the support system 13 includes a first auxiliary support rod 133 and a second auxiliary support rod 134. The first auxiliary support rod 133 is located between the upper platform 11 and the lower platform 12. More specifically, the first auxiliary support rod 133 can be arranged obliquely or vertically. The second auxiliary support rod 134 is located between the lower platform 12 and the integral anti-sinking seat 132. More specifically, the second auxiliary support rod 134 can be arranged horizontally, obliquely or vertically, and the second auxiliary support rod 134 can be connected between the columns 131, between the columns 131 and the lower platform 12, or between the columns 131 and the integral anti-sinking seat 132.

[0045] In one embodiment, Figure 3 and Figure 5 As shown, the rock-embedded construction equipment also includes a hydraulic cylinder 14, and a plurality of hydraulic cylinders 14 are arranged around each upper rock-embedded hole 111 and each lower rock-embedded hole 121. In the figure, four hydraulic cylinders 14 are arranged around each upper rock-embedded hole 111 and each lower rock-embedded hole 121. With this design, when the casing 3 is sunk through the upper rock-embedded hole 111 and the lower rock-embedded hole 121, the verticality of the casing 3 can be guaranteed under the supporting action of the hydraulic cylinder 14, and the verticality of the casing 3 can be controlled within 1‰.
