Meanwhile, the offshore wind power resources are vast in | territory and huge in potential, and are particularly rich, high-quality and clean novel | energy resources for some countries with long coastlines. Infrastructures of offshore | wind farms mainly include a gravity type, a single pile type, a suction type, a three-pile | (multi-pile) jacket type and a floating type. Grouting connection is a typical method for | connection between an offshore fan supporting structure and a pile foundation. | Moreover, grouting is also the key technology of construction of the whole fan | infrastructure. The success of the grouting directly affects environmental loading | resistance and service life of the fan infrastructure, while validity of plugging of the | grouting material is a very important condition of judging whether the grouting is | successful. In most of the existing plugging devices, a plugging block and a plugging | agent are used together; operations are time-consuming; the plugging agent is disposable; plugging cost is relatively high; and working efficiency is low.

Based on this, the present invention designs a grouting plugging device for grouting construction of offshore wind power infrastructures to solve the above technical problems.

Embodiments: Referring to Figs. 1-4, the present invention provides a technical solution as follows: a grouting plugging device for grouting construction of offshore wind power infrastructures includes a bracket 1. The bracket 1 has a U-shaped cross section. One open end of the bracket 1 is connected with a plugging device 2; the plugging device 2 includes a plugging block 3, a first sealing ring 4 and a second sealing ring 5; the first sealing ring 4 and the second sealing ring 5 are reusable; the first sealing ring 4 is sleeved on an outer wall of the plugging block 3; an outer wall of the first sealing ring 4 is abutted against an inner wall of a grouting mouth on a pipe pile hoop body 15; the | outer wall of the plugging block 3 is provided with a first bulge 6; the upper end of the | first sealing ring 4 is abutted against the first bulge 6, and the lower end of the first | sealing ring 4 is abutted against a second bulge 16 in the grouting mouth on the pipe | pile hoop body 15; the second sealing ring 5 is sleeved on the outer wall of the first | bulge 6; the plugging block 3 is provided with a third bulge 7 matched with the outer | wall of the pipe pile hoop body 15; one end of the second sealing ring 5 is abutted j against the third bulge 7, and the other end of the second sealing ring 5 is abutted | against the pipe pile hoop body 15; and the plugging block 3 is fixedly connected with | the bracket 1 by virtue of the third bulge 7.

] Another open end of the bracket 1 is connected with a clamping device 8 used for | fixing the plugging device 2 on the outer wall of a pipe pile; the clamping device 8 is | connected with a clamping block 9; one side of the clamping block 9 close to the pipe | pile hoop body 15 is connected with a soft gasket 10; and the soft gasket 10 is abutted | against the outer wall of the pipe pile hoop body 15.

| Specifically, the clamping device 8 includes a quick clamp 11 and a reducing | sleeve 13; the quick clamp 11 has a model of WDC303-EM; an ejector rod in the quick ;

clamp 11 is in screwed connection with the reducing sleeve 13; and the reducing sleeve 13 is rotationally connected with the clamping block 9. A distance from the clamping block 9 to the side of the bracket 1 is adjusted by virtue of the reducing sleeve 13, so as to adapt to pipe pile hoop bodies 15 of different diameters.

Specifically, reinforcing ribs 12 are arranged on both sides of the bracket 1. Due to the reinforcing ribs 12, both sides of the bracket 1 are prevented from opening under stress when the pipe pile hoop body 15 is ejected by the quick clamp 11. Specifically, antiskid stripes are arranged on one side of the soft gasket 10 close to the pipe pile hoop body 15. Due to the antiskid stripes, frictional force between the soft gasket 10 and the pipe pile hoop body 15 is increased, thereby preventing the bracket 1 | from sliding down from the outer wall of the pipe pile hoop body 15. | Specifically, the two open ends of the bracket 1 are respectively connected with | supporting rods 14; each supporting rod 14 is connected with the pipe pile hoop body 15; | and the supporting rods 14 are hinged with the bracket 1. In front of the device and the | pipe pile hoop body 15, the supporting rods 14 rotate outwards, so that the bracket 1 | may be sleeved on the outer wall of the pipe pile hoop body 15. After the bracket 1 is | placed, the supporting rods 14 are connected with the pipe pile hoop body 15. By virtue | of the connection between the supporting rods 14 and the pipe pile hoop body 15, a | problem that the device is infirm in fixation because the open ends of the bracket 1 are | opened under stress when the pipe pile hoop body 15 is ejected by the quick clamp 11 is | solved. | One specific application of the present invention is as follows: when the present | invention is used, the plugging block 3 is aligned at the grouting mouth formed in the | pipe pile hoop body 15, and the handle in the quick clamp 11 is pressed by hand, so that | the ejector rod in the quick clamp 11 stretches out, and the clamping block 9 and the | soft gasket 10 approach the outer wall of the pipe pile hoop body 15 under drive of the ejector rod until the ejector rod of the quick clamp 11 reaches an extreme stretching position. Thus, the device is fixed on the outer wall of the pipe pile hoop body 15.

When the device is fixed on the outer wall of the pipe pile hoop body 15, the first sealing ring 4 is extruded by the first bulge 6 and the second bulge 16 and deformed; thus, the gap between the plugging block 3 and the grouting mouth is further filled, thereby preventing the grouting material from leaking out of the grouting mouth. The second sealing ring 5 is extruded by the outer wall of the pipe pile hoop body 15 and the third bulge 7 and deformed, and the gap between the plugging device 2 and the grouting mouth is filled, thereby preventing the grouting material from leaking out of the plugging device 2. The second sealing ring 5 is a second seal, for preventing seal failure of the first sealing ring 4. Meanwhile, by virtue of the second sealing ring 5, a problem that the quick clamp 11 is labor-consuming to press because two hard surfaces are in mutual abutment when the third bulge 7 and the pipe pile hoop body 15 are clamped is solved.

When the pipe pile hoop bodies 15 of different diameters need to be plugged, the reducing sleeve 13 is rotated by a spanner, and thus the distance from the clamping block 9 to the side of the bracket 1 is adjusted, so that clamping force of the device is invariable when the pipe pile hoop bodies 15 of different diameters are plugged.
