In addition, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
Example 1
The embodiment provides a specific implementation manner of a pile foundation protection structure, as shown in fig. 1 and fig. 2, a solidified soil layer is filled into a scouring pit, wherein the solidified soil layer comprises a base layer 5 and a cover layer 2, the base layer 5 is filled into the scouring pit and can be well attached to the outer wall of the pile foundation 1 without causing damage such as scratches on the outer wall of the pile foundation 1, meanwhile, the cover layer 2 is laid above the base layer 5 and can be closely attached to the mud surfaces of the base layer 5 and the seabed 3, the solidified soil layer comprises mud and a curing agent, the curing agent can enable substances such as secondary minerals and the like in the solidified soil layer and the mud surface of the seabed 3 to generate a series of hydration and hydrolysis reactions, so as to generate a large amount of various hydration gelled products, the gelled products can be cemented and wrap fine particles in the mud surface to granulate the fine particles, and a loose soil body is cemented into a whole with, can consolidate around the pile foundation 1 to prevent to produce again around the pile foundation 1 and erode the hole, guarantee the stability of pile foundation 1 work.
The requirement on the solidified soil layer in the washout pit is low, the solidified soil layer is divided into the base layer 5 and the covering layer 2, less curing agent can be used in the base layer 5, the cost can be saved, and the influence of small strength on the stability of the pile foundation 1 can be ignored due to the fact that the curing agent is arranged in the washout pit; the curing agent that adds in the overburden 2 is more, and intensity is great, forms gentle slope structure around pile foundation 1, and is not washd the effect better around the protection pile foundation 1.
Overburden 2 is filling and is continuing to fill after filling full scouring pit, makes overburden 2 exceed the top that erodees the pit, forms the gentle slope structure around pile foundation 1, promotes pile foundation 1's stability, prevents to form again around pile foundation 1 and erodees the pit.
The slump of the base layer 5 is 10 cm-15 cm, the slump of the covering layer 2 is 25 cm-35 cm, wherein the slump is an index for measuring the fluidity of a mixture of the slurry and the curing agent, the slump is tested by adopting a trumpet-shaped slump bucket with an upper opening of 100mm, a lower opening of 200mm and a height of 400mm, the mixture of the slurry and the curing agent is filled into the slump bucket, the height of the mixture of the slurry and the curing agent is equal to that of the upper opening, then the slump bucket is pulled up, the mixture of the slurry and the curing agent flows under the action of self gravity, and a value obtained by subtracting the height of the mixture of the slurry and the curing agent after flowing by the height of the bucket (400mm) is called as the slump. Stratum basale 5's mobility is less, it forms around pile foundation 1 to erode the hole, it is nearer apart from scouring pit bottom in the scouring pit, its radial distance is less, the mobility requirement on solidification soil layer is just lower, the solidification soil layer that fills as long as can fill the scouring pit around pile foundation 1, can closely paste 1 outer wall of pile foundation, overburden 2 is laid in stratum basale 5 top, overburden 2 need form a gentle slope structure around pile foundation 1, radial distance is great, the mobility requirement on solidification soil layer is higher, when needing to make overburden 2 lay in stratum basale 5 top, also can form the gentle slope structure under self's mobility, can not form the scouring pit here because of erodeing around protection pile foundation 1.
The horizontal plane that scours away the hole top place is the reference surface, and the distance of the upper surface of stratum basale 5 apart from the reference surface does not do the restriction, as long as its and pile foundation 1 diameter's ratio is not less than 1: 6.3, specifically, in this embodiment, the diameter of pile foundation 1 is 6.3m, and the distance of stratum basale 5 is 1m from the datum plane, leaves some space in scouring pit top position, because stratum basale 5 intensity is less than overburden 2, is not suitable for using stratum basale 5 to fill scouring pit, needs to use overburden 2 to continue to fill to form the gentle slope structure, firm seabed 3 around pile foundation 1.
The cover layer 2 comprises a main body layer 21 and a protective layer 22, wherein the thickness of the protective layer 22 is smaller at the edge until the protective layer forms a smooth plane with the seabed 3, and the water flow scouring is effectively prevented.
Example 2
In this embodiment, a specific implementation manner of the protection method is provided, in this application, the diameter of the pile foundation 1 is 6.9m, after the pile foundation 1 is inserted on the seabed 3, the solidified soil is manufactured by using slurry and a curing agent, wherein a ratio of mass ratio of the slurry to the curing agent in the base layer 5 is in a range of 6.4% to 7.8%, and a ratio of mass ratio of the slurry to the curing agent in the cover layer 2 is in a range of 11.4% to 13.9%, in this embodiment, the base layer 5 is mixed by using 7% of the solidified soil, the cover layer 2 is mixed by using 12.5% of the solidified soil, so as to obtain the solidified soil with two slump requirements, then the outlet end of the hydraulic fill pipe 4 is extended to the upper part of a flushing pit around the pile foundation 1, the base layer 5 is filled until the distance between the upper surface of the base layer 5 and the reference surface is about 1m, the filling of the base layer 5 is stopped, the hydraulic fill pipe 4 is, carry out overburden 2's packing, overburden 2 is filling to pile foundation 1 around the back, lay in basal layer 5 top, and flow under self gravity influence, along with constantly filling overburden 2, overburden 2 is bigger and bigger more in area around pile foundation 1, when the distance of overburden 2's edge apart from pile foundation 1 periphery wall is greater than or equal to 17m, stop filling, at this moment, overburden 2 still can continue to flow one section distance, overburden 2 forms main part layer 21 on seabed 3 flow in-process, main part layer 21 is the gentle slope structure, and form protective layer 22 at main part layer 21 edge, this scheme uses basal layer 5 to fill earlier and erodees the hole, use overburden 2 to fill around pile foundation 1 again, form the solidification soil layer after a period, do not erode by rivers around the protection pile foundation 1, can not form and erode the hole.
It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications therefrom are within the scope of the invention.
