Embodiment Construction

[0031] like Figure 1-Figure 4 As shown, an offshore pile anti-wind and wave device of the present invention includes a rubber disc body 1 , an air cavity inflation matching device for the rubber disc body, and a ring thin-walled steel ferrule 2 screws.

[0032] The connection at the flange 12 of the rubber upper plate 9 and the rubber lower plate 10 is made in one piece.

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

[0034] Inflatable holes are prefabricated on the surface of the rubber upper plate 9. 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. Under a certain air pressure, the surface of the rubber lower plate 10 is gradually expanded, and the expanded rubber upper plate 9 The rubber lower plate 10 is in the shape of a downwardly convex ring, and the rubber lower plate 10 is in t...

Abstract

An anti-wind and wave device for offshore piles comprises a rubber disc body, an inflatable supporting device inside the disc body, a circular thin-walled steel hoop, and screws. The rubber disc body includes a rubber upper plate and a rubber lower plate, and the lower surface of the rubber upper plate ring-shaped edge and the rubber lower plate ring-shaped edge upper surface are prefabricated as a whole; the rubber plate body air chamber inflation matching device includes Inflatable nozzle, octagonal screw cap, air guide tube, gas valve switch, air pressure gauge, inflatable air pump. The advantage of this patent is that: when the pile body undergoes a large displacement and deformation under the action of horizontal load, the lower surface of the plate body contacts with the silt soil to generate a vacuum negative pressure effect, which stabilizes the horizontal load resistance of high-pile marine buildings Compared with other methods, the construction operation is quick and the project cost is low.

Description

technical field [0001] The invention relates to an auxiliary device for pile foundation engineering, in particular to the field of geotechnical pile foundation engineering, in particular to a marine pile anti-wind and wave device that plays a stabilizing role in resisting horizontal loads of high-piled marine buildings. Background technique [0002] The pile foundation of offshore buildings will be affected by offshore wind loads and current loads during construction or use. Compared with low-pile foundations, high-pile foundations have smaller horizontal bearing capacity and horizontal stiffness, and are prone to larger horizontal displacements under the action of horizontal loads. [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, improve the horizontal stiffness of the pile body, or increase the depth of the pile body inserted into the lower soil layer, ther...
