Embodiment Construction

[0031] Such as Figure 1-Figure 4 As shown, a novel offshore pile anti-wind and wave device of the present invention includes a rubber disc body 1, a rubber disc body air chamber inflation matching device, and a circular thin-walled steel hoop 2 screws.

[0032] The rubber upper plate 9 is connected with the flange 12 of the rubber lower plate 10 and is made in an integrated manner.

[0033] When the rubber disc body 1 is prefabricated, an installation operation space is reserved according to the diameter of the designed pile.

[0034] Inflatable holes are prefabricated on the surface of the rubber upper plate 9, and the inner space of the rubber upper plate 9 and the rubber lower plate 10 forms an inflatable cavity 12 that can be filled with gas. It is a convex circular ring shape, and the rubber lower wall 10 is a convex circular ring shape, forming an integral groove 13. After the rubber lower wall 10 is expanded, the air between the muddy soil is squeezed under the action...

Abstract

A novel offshore pile anti-stormy-wave device comprises a rubber plate body, a plate body internal inflation matched device, a circular thin-walled steel sleeve and a screw. The rubber plate body comprises a rubber upper plate and a rubber lower plate. The lower surface of the circular edge of the rubber upper plate and the upper surface of the circular edge of the rubber lower plate are connectedinto a whole. The rubber plate body air cavity inflation matched device comprises an inflation nozzle, an eight-square screw nut, an air guide pipe, an air valve switch, an air pressure gauge and aninflation air pump. The novel offshore pile anti-stormy-wave device has the advantages that when a pile body generates great displacement and deformation under the action of horizontal loads, the lower surface of the plate body makes contact with silt and a vacuum negative pressure effect is generated, the anti-stormy-wave device has a stabilizing effect for allowing a high-pile marine building toresist horizontal loads, horizontal displacement is reduced, and compared with other methods, construction operation is rapid and construction cost is low.

Description

technical field [0001] The invention relates to an auxiliary device for pile foundation engineering, which specifically belongs to the field of geotechnical pile foundation engineering, in particular to a novel offshore pile anti-wind and wave device which stabilizes high-pile marine buildings against horizontal loads. Background technique [0002] During the construction or use of the pile foundation of offshore buildings, it will be affected by offshore wind loads, water flow loads, etc. Compared with the low pile foundation, the horizontal bearing capacity and horizontal stiffness of the high pile foundation are smaller, and it is easy to produce a large horizontal displacement under the horizontal load. [0003] At present, the commonly used method to solve the horizontal displacement of high pile foundation is to increase the cross-sectional area of ​​the pile body, increase the horizontal stiffness of the pile body or increase the depth of the pile body inserted into t...
