Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
Referring to fig. 1 and 2, fig. 1 is a specific structural view of a jacket according to an embodiment of the present invention, and fig. 2 is a specific structural view of a pile shoe according to an embodiment of the present invention.
The utility model provides a pile body sealing device, this sealing device wholly sets up on pile shoe 1, and in this embodiment, this sealing device is applied to marine booster station, and jacket structure is one of marine wind-powered electricity generation fan basis, marine booster station basis and the main foundation structure type of marine oil production platform basis. In this embodiment, the pile shoe 1 is fixed around the jacket. The pile shoe 1 is arranged in a cylindrical shape for the penetration installation of the pile body, and after the installation of the pile body is finished, grouting is needed to be performed in a gap between the pile shoe 1 and the pile body so as to firmly fix the pile shoe 1 and the pile body. The sealing device is just used for sealing the gap between the pile shoe 1 and the pile body, so that seabed sludge is prevented from entering a grouting area, and once a large amount of sludge passes through the sealing device, the grouting quality is greatly influenced.
The sealing device further comprises an isolation structure and a sealing structure, wherein the isolation structure comprises a spacer 2, and in the present embodiment, the spacer 2 is an isolation film. Both ends of the shoe 1 are open, and the spacer 2 seals the end of the shoe 1 that contacts the sea floor. The sealing structure comprises a sealing ring 3 for sealing a gap formed between the pile shoe 1 and the pile body, the sealing ring 3 is arranged in a hollow mode, an inflation tube 4 is fixed outside the pile shoe 1, and one end of the inflation tube 4 is communicated with the inside of the sealing ring 3. Therefore, in the present embodiment, the seal ring 3 is an expandable and contractible active seal member.
Illustratively, during construction using the sealing device, the pile shoe 1 is installed, and the isolating piece 2 at the bottom of the pile shoe isolates silt on the seabed outside the pile shoe 1. When the pile body is hoisted, the pile body is inserted into the pile shoe 1 from top to bottom, the end part of the pile body gradually crosses over the sealing structure along with the penetration of the pile body, the isolating piece 2 is punctured when the pile body continues to move downwards, the pile body is inserted into the silt on the seabed until the required depth is reached, and the installation process of the pile body is finished at this moment. Before grouting construction, a gap formed by a pile body and a pile shoe 1 needs to be sealed, sealing work only needs to be carried out by externally connecting inflation equipment on an inflation tube 4, gas is inflated into a sealing ring 3 to promote the sealing ring 3 to integrally expand, the gap formed by the pile body and the pile shoe 1 is gradually sealed in the expansion process, after the sealing is in place, the inflation tube 4 is closed through a ball valve, the inflation equipment is removed, and the sealing work is finished.
It should be noted that, compared with the prior art, the sealing ring 3 with the active sealing function can perfectly deal with the problems encountered by the pile body, for example, the problem that the sealing effect is invalid due to the fact that the pile body is not installed in a centering manner, and can effectively prevent seabed surface soil from entering a grouting area, so that the grouting quality is ensured, and the sealing ring has an excellent sealing effect.
More preferably, a guide block 5 is arranged inside the pile shoe 1, in this embodiment, the guide block 5 is annularly arranged, when the pile body is installed and enters the pile shoe 1, the seal ring 3 is in a shrinkage pile body, the guide block 5 plays a role in guiding to cross the seal ring 3, and the width of the guide block 5 is greater than the width of the seal ring 3 in a shrinkage state. Through the arrangement, when the pile body enters the area of the sealing structure, the pile body is guided by the guide block 5, so that the situation that the pile body directly collides with the sealing structure can be avoided, and the sealing structure is protected.
In this embodiment, the guide block 5 is provided with a guide surface 51 on a side close to the center of the shoe 1, and the guide surface 51 is inclined in a direction facing the center of the shoe 1 and facing away from the seal ring 3. The pile body is aligned to the center of the pile shoe 1 under the guidance of the guide surface 51, so that the installation efficiency of the pile body is improved, and the overall installation quality of the pile body can be improved.
Preferably, a fender 6 is fixed in the pile shoe 1 in a surrounding manner, and the fender 6 is positioned below the seal ring 3 and above the spacer 2. In the process of pile body installation, after the pile body passes through the spacer 2, the spacer 2 is attached to the surface of the pile body, and the whole spacer 2 is pierced, so the sealing effect is reduced, and the mud guard 6 can effectively prevent the seabed surface soft soil from entering the sealing structure to influence the grouting quality in the construction process, thereby achieving the effect of double protection.
In the present embodiment, the fender 6 is provided on the inner wall of the pile shoe 1 in a barbed shape in the longitudinal section, and the fender effect of the fender 6 can be further improved by providing the barbed shape. Meanwhile, the fender 6 is a plastic member.
The foregoing is a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations are also considered as the protection scope of the present invention.
