A specific prefabricated high pile cap foundation 100 structure according to an embodiment of the present invention is described below with reference to fig. 1-7.
As shown in fig. 1, the high pile cap foundation 100 according to the embodiment of the present invention includes six pile foundations 10, a bottom plate 20, a concrete cap 30, and tendons 40. The pile foundation 10 is inserted into the seabed at the bottom and extends above the sea surface at the top. The top of the pile foundation 10 is matched with the bottom plate 20, a concrete bearing platform 30 is arranged on the bottom plate 20, the concrete bearing platform 30 is formed by splicing precast concrete blocks 31, prestressed ribs 40 are sleeved on the outer peripheral surface of the formed concrete bearing platform 30, the stability of the concrete bearing platform 30 is enhanced, the high pile bearing platform foundation 100 is an offshore wind turbine foundation, and an offshore wind turbine tower is arranged on the concrete bearing platform 30.
Specifically, as shown in fig. 2, the pile foundations 10 are arranged obliquely in the sea, the bottoms of the pile foundations 10 are inserted into the sea bed, the tops extend out of the sea surface, and six pile foundations 10 are arranged at intervals in the circumferential direction and the tops are gathered. The pile foundation 10 is provided with protruding brackets 11 at the top. As shown in fig. 2, the bottom plate 20 is circular, and a plurality of through holes are formed in the bottom plate 20 at intervals along the circumferential direction thereof. And, the number and positions of the through holes correspond to those of the tops of the pile foundations 10, that is, one pile foundation 10 for each through hole.
As shown in fig. 3 to 4, when the base plate 20 is installed, the tops of the pile foundations 10 penetrate through the through holes in the base plate 20 in a one-to-one correspondence manner until the bottoms of the base plate 20 are abutted against the tops of the brackets on the pile foundations 10, so that the base plate 20 is fixed at the corresponding position of the pile foundations 10, and the base plate 20 is limited. The bracket 11 of the pile foundation 10 is adapted to bear the downward pressure of the bottom plate 20.
As shown in fig. 5 to 6, after the bottom plate 20 is installed, a concrete cap 30 is placed on top of the bottom plate 20. The concrete cap 30 is used for bearing, distributing and transmitting dynamic and static loads suffered by the offshore wind turbine, and a plurality of embedded anchor bolts 32 are arranged in the middle of the concrete cap 30 and used for being connected with the offshore wind turbine tower, that is, the offshore wind turbine tower is connected with the high pile cap foundation 100 of the offshore wind turbine through the embedded anchor bolts 32 embedded in the middle of the concrete cap 30.
As shown in fig. 5, the top of the pile foundation 10 protrudes relative to the top of the bottom plate 20 after passing through the through holes on the bottom plate 20, in order to limit the concrete cap 30, through holes are formed in positions corresponding to the tops of the pile foundations 10 at the bottom of the concrete cap 30, the tops of the pile foundations 10 extend into the through holes of the concrete cap 30, so that the concrete cap 30 is limited, and the concrete cap 30 is better abutted against the top of the bottom plate 20.
The concrete cap 30 includes a plurality of precast concrete segments 31, and is formed by splicing the precast concrete segments 31. In the embodiment shown in fig. 5, a part of the embedded anchor bolts 32 are arranged on the precast concrete segments 31, and after the precast concrete segments 31 are spliced into the concrete cap 30, the parts of the embedded anchor bolts 32 are spliced into a complete embedded anchor bolt 32. In other embodiments, the embedded anchor 32 can also be embedded completely in a precast concrete segment 31.
Further, adjacent precast concrete segments 31 are provided at the contact surface with mutually matched concave-convex structures, which are engaged with each other, that is, the concave-convex structures are engagement structures 33. The engagement structures 33 of adjacent precast concrete segments 31 are matched and engaged with each other. The arrangement of the engagement structure 33 increases the shearing resistance between the precast concrete segments 31, can avoid the precast concrete segments 31 from generating relative displacement after being spliced and assembled into the concrete cap 30, and avoid dislocation between the precast concrete segments 31, so that the concrete cap 30 formed by splicing a plurality of precast concrete segments 31 has better stability.
Furthermore, the shapes of the precast concrete segments 31 can be the same, the precast concrete segments 31 with the same shape are more convenient to construct during construction, the construction efficiency is improved, and the complexity and cost of engineering are reduced. The precast concrete segments 31 are sequentially spliced along the circumferential direction of the concrete cap 30 to form the concrete cap 30, that is, the concrete cap 30 is formed by sequentially splicing the precast concrete segments 31 along the circumferential direction. When the shapes of the precast concrete segments 31 are identical to each other, it is explained that the corresponding central angles of the precast concrete segments 31 are identical.
Optionally, the number of precast concrete segments 31 may be 2-16, for example, 2, 4, 8, 12, 16, it is understood that setting more precast concrete segments 31 may make the weight of each concrete segment lower, and the hoisting of the concrete platform can be completed by using a crane with a smaller load, so as to facilitate the transportation and installation of the precast concrete segments 31.
Specifically, as shown in fig. 5 and 6, the number of precast concrete segments 31 is two, the precast concrete segments 31 are semicircular, and the shapes of the two precast concrete segments 31 are identical to each other, that is, the corresponding central angle of each precast concrete segment 31 is 180 °, and the two precast concrete segments 31 are spliced to form the concrete cap 30.
In other embodiments, the number of precast concrete segments 31 may be greater than two, and it is understood that the number of precast concrete segments 31 corresponds to the central angle of each precast concrete segment 31, for example, n precast concrete segments 31, and the central angle of each precast concrete segment 31 corresponds to 360 °/n.
For example, in one embodiment, the number of precast concrete segments 31 is four, the precast concrete segments 31 have a fan-shaped structure having the same shape as each other, and the corresponding central angle of the precast concrete segments 31 is 90 °. The four precast concrete segments 31 are sequentially spliced in the circumferential direction around the center of the bottom plate 20 to form a disk-shaped concrete cap 30.
The concrete cap 30 of the high pile cap foundation 100 is formed by splicing a plurality of precast concrete blocks 31, and under the same engineering standard requirements, compared with the traditional site construction of the concrete cap 30, the concrete of the precast concrete blocks 31 is poured and maintained on land, so that the offshore construction time is reduced, and the construction efficiency of the high pile cap foundation 100 is improved.
Further, after the precast concrete segments 31 are spliced, grouting materials are filled between contact surfaces of the precast concrete segments 31, between gaps between the concrete cap 30 and the bottom plate 20 and in through holes of the concrete cap 30, so that the whole high-pile cap foundation 100 is fixed, and the stability of the high-pile cap foundation 100 is improved.
As shown in fig. 1, after the concrete platform 30 is built, a plurality of prestressed tendons 40 are further disposed on the outer peripheral surface of the concrete platform 30, and the prestressed tendons 40 can reinforce the connection of a plurality of precast concrete blocks 31, reduce the occurrence of cracks of the concrete platform 30, and make the bearing capacity of the concrete platform 30 stronger. And meanwhile, the prestressed tendons 40 can reach the same engineering standard under the condition of smaller concrete weight, and meet the requirements of offshore wind power foundation engineering.
