Problems solved by technology

However, the pullout and compressive bearing capacity of the bucket foundation is limited by the diameter and height of the bucket foundation, and its stability is easily affected by the fluidity of mud, sand and soft soil
The main problem with the existing types of foundation structures is that due to the complex loading conditions and environmental conditions of coastal and marine engineering, it is difficult to realize that the foundation foundation can simultaneously withstand large uplift loads, horizontal loads and down pressure loads

Embodiment Construction

[0016] The present invention will now be described in further detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0017] The invention discloses a bucket foundation reinforcement method for a sandy foundation, comprising the following steps:

[0018] S1: Counterweight the barrel foundation 2, and make the weight of the counterweight more than twice the weight of the barrel foundation 2 itself;

[0019] S2: implant the barrel foundation 2 into the predetermined elevation position of the foundation;

[0020] S3: After the barrel foundation 2 is implanted into the sandy foundation, vibrate to rearrange the sand grains, so that the contact between the barrel foundation 2 and the sand grains is dense;

[0021] S4: After the barrel foundati...

Abstract

The invention relates to a bucket foundation reinforcing method of a sandy foundation. The method is characterized by comprising the following steps of: (S1) carrying out weight balance on the bucket foundation and ensuring that the balanced weight is over one time larger than the self weight of the bucket foundation; (S2) embedding the bucket foundation into a preset elevation position of a foundation; (S3) embedding the bucket foundation into a sandy foundation, and vibrating to ensure that sand grains are renewedly arrayed and the bucket foundation is in dense contact with the sand grains; and (S4) after the bucket foundation is primarily stabilized in the sandy foundation, passing a pile through a cavity arranged in the center of a bucket top cover and embedding into the preset elevation position of the sandy foundation. The bucket foundation reinforcing method of the sandy foundation has the advantages of high bearing capacity, strong displacement resistance and good stability.

Description

technical field [0001] The invention relates to an engineering foundation reinforcement method, in particular to a barrel foundation reinforcement method for a sandy foundation. Background technique [0002] At present, pile foundations or gravity foundations are usually used for foundation structures of wharf engineering, coastal engineering and ocean engineering, and barrel foundations studied in recent years. The gravity foundation mainly uses the self-weight of the foundation to maintain the stability of itself and the structure, bear the load and spread the stress to the subsea foundation. However, the gravity foundation is large in size and is greatly affected by wind, waves, and ocean currents, which may easily cause the foundation to become unstable. The pile foundation is that the pile bears the load through the friction of the pile side surface of the pile implanted in the seabed foundation and the end resistance of the pile end. The pile foundation has high bearin...
