Cause height of pile top to differ, need to carry out cutting the work such as stake.Cut a difficulty under water big, and strengthen construction period and expense, with
Time cause potential safety hazard to catheterostat basis.
Utility model content
In view of the deficiencies in the prior art, technical problem to be solved in the utility model is to provide a kind of novel in design, knot
The Length discrepancy lower limb offshore wind farm conduit that structure is simple, save material, environmental suitability is strong, easy construction, expense are low and safe and reliable
Frame basis.
In order to solve the problems referred to above, the technical solution of the utility model is: a kind of be applicable to sea bottom complex geological conditions
Length discrepancy lower limb offshore wind farm catheterostat basis, including the main pipe lower limb that at least three is different in size, adopts between described main pipe lower limb
Being distributed with polygon, the height of pile top between difference in height pile foundation corresponding with seabed between each main pipe lower limb is poor consistent, appoints
Connected into the lattice catheterostat basis of entirety by diagonal brace between two the main pipe lower limbs anticipating adjacent.
Preferably, described diagonal brace is X-type diagonal brace, K-type diagonal brace or the combination of the two.
Preferably, described main pipe lower limb is to continue downwards to extend along the gradient that catheterostat is basic.
Preferably, described main pipe lower limb and the angle of horizontal plane are less than catheterostat side of the base plate and the angle of horizontal plane.
Compared with prior art, this utility model has the advantages that owing to catheterostat have employed unequal leg structure,
When being applied to Sea Bottom with Complicated Geological Conditions and causing driven pile elevation difference, it is effectively reduced and cuts stake or other equivalent process
Workload, be greatly shortened construction period, convenient construction, reduce waste of material simultaneously.Additionally, Length discrepancy lower limb structure can reduce base
Plinth cost and the weight of catheterostat itself, have obvious social benefit and economic benefit.Cover simultaneously for coastal waters sea bed
Layer is shallow, and in order to meet foundation bearing capacity, pile foundation generally requires embedding rock, relative to the many pile foundations of conventional pilot pipe support, Length discrepancy lower limb sea
Windward conductance pipe support basis also can reduce difficulty of construction and quantities.

Detailed description of the invention
In order to allow features described above of the present utility model and advantage become apparent, special embodiment below, and coordinate accompanying drawing,
It is described in detail below.
As shown in Fig. 1 ~ 4, a kind of Length discrepancy lower limb offshore wind farm catheterostat basis being applicable to sea bottom complex geological conditions, bag
Include the main pipe lower limb 100 that at least three is different in size, between described main pipe lower limb 100, use polygon distribution, each main pipe
Height of pile top between difference in height between lower limb 100 pile foundation corresponding with seabed 300 is poor consistent, two main pipes of arbitrary neighborhood
Connected into the lattice catheterostat basis of entirety by diagonal brace 200 between lower limb 100.
Wherein, top, described catheterostat basis is used for connecting fan tower, and bottom is for connecting the stake that height of pile top is different
Basis 300.
Wherein, described main pipe lower limb 100 catheterostat foundation bottom setting angle or for along catheterostat basis inclining
Gradient continues downwards to extend, or is the angle less than catheterostat side of the base plate with horizontal plane of the angle with horizontal plane.
Embodiment one: as shown in Figure 1 and 2, this catheterostat basis include three main pipe lower limbs different in size 101,102,
103, use Triangle-Profile, described main pipe lower limb 101,102,103 and horizontal plane between three main pipe lower limbs 101,102,103
Angle less than the angle of catheterostat side of the base plate and horizontal plane, described diagonal brace 200 is X-type diagonal brace.
Embodiment two: as shown in Fig. 3 ~ 4, this catheterostat basis include four main pipe lower limbs different in size 101,102,
103,104, use tetragon distribution between four main pipe lower limbs 101,102,103,104, described main pipe lower limb 101,102,
103,104 with the angle of horizontal plane less than the angle of catheterostat side of the base plate with horizontal plane, described diagonal brace 200 is X-type diagonal brace and K
The combination of type diagonal brace.
The main pipe lower limb that offshore wind farm catheterostat basis instrument is different in size, changes leading of long legs such as in the past directly utilizing
Pipe support is supported in stake, becomes original catheterostat being made up of Length discrepancy lower limb and corresponding diagonal brace two parts.Should at Practical Project
Used time, as run into Sea Bottom with Complicated Geological Conditions, during driven pile crest level difference, the Length discrepancy lower limb bottom available catheterostat, make
Obtain conduit quantity and length arbitrarily can adjust according to seabed driven pile crest level or other needs, select flexibly, reduce consumptive material.
Body steel quantity consumption is not only saved on catheterostat basis after improvement, also can significantly reduce foundation construction workload, shortens the construction period,
There is obvious economic benefit.
As shown in Fig. 1 ~ 4, the construction method on a kind of Length discrepancy lower limb offshore wind farm catheterostat basis, comprise the following steps:
