[0030] Reference Figure 1 and Figure 2 The utility model provides an embodiment: a bored pile suitable for underwater construction, comprising an installation pipe 1, a connecting pipe 5 and a fixed pipe 15, wherein a clamping groove 3 is provided inside the installation pipe 1 and the connecting pipe 5, and a limiting groove 4 is provided inside the installation pipe 1 and the connecting pipe 5, and a clamping ring 6 is fixedly connected to the upper surface of the connecting pipe 5 and the fixed pipe 15, and a clamping block 7 is fixedly connected to the side wall of the clamping ring 6, and the side wall of the clamping ring 6 is slidably connected to the inside of the clamping groove 3, and the side wall of the clamping block 7 is slidably connected to the inside of the limiting groove 4, and a clamping plate 1 8 is fixedly connected to the side wall of the connecting pipe 5 and the fixed pipe 15, and a clamping plate 2 9 is fixedly connected to the side wall of the connecting pipe 5 and the installation pipe 1, and a fixing component is arranged inside the clamping plate 1 8 and the clamping plate 2 9, and the fixing component comprises a fixing bolt 10, and the side wall of the fixing bolt 10 is threadedly connected to the inside of the clamping plate 1 8 and the clamping plate 2 9.

[0031] When using the equipment for drilling and grouting work in underwater construction, it is necessary to assemble the equipment into a suitable length according to the specific requirements of the construction. During the splicing process, insert the clamping ring 6 on the connecting pipe 5 into the clamping groove 3 opened inside the mounting pipe 1 to ensure the tight connection between the connecting pipe 5 and the mounting pipe 1, and slide the clamping block 7 inside the limiting groove 4 to limit the clamping ring 6. Next, insert the fixing bolt 10 into the inside of the clamping plate 1 8 and the clamping plate 2 9, and rotate them to fix the connecting pipe 5 and the mounting pipe 1. When the length of the connecting pipe 5 is not enough, the connecting pipe 5 can be assembled again. Finally, the fixing pipe 15 is connected to the bottommost connecting pipe 5, and is also fixed using the clamping ring 6 and the fixing bolt 10.

[0032] Reference Figure 3A slide groove 11 is provided inside the mounting tube 1, the connecting tube 5 and the fixed tube 15, a slide groove 2 12 is provided inside the clamping ring 6, the slide groove 11 and the slide groove 2 12 are on the same vertical line and are connected, a drain plate 13 is provided inside the mounting tube 1, the side wall of the drain plate 13 is slidably connected inside the mounting tube 1, the connecting tube 5 and the fixed tube 15, a slider 14 is fixedly connected to the side wall of the drain plate 13, and the side wall of the slider 14 is slidably connected inside the slide groove 2 12 and the slide groove 11, a fixing frame 16 is fixedly connected to the side wall of the fixed tube 15, and a ground nail 17 is fixedly connected inside the fixing frame 16, a threaded groove 2 is provided inside the mounting tube 1, a floating plate 18 is provided on the top of the mounting tube 1, a threaded ring 19 is fixedly connected to the inner wall of the floating plate 18, and the inner wall of the threaded ring 19 is threadedly connected inside the threaded groove 2.

[0033] When the equipment is assembled, the threaded ring 19 is twisted and installed in the threaded groove 2 opened inside the mounting tube 1. When the equipment is inserted into the water, the floating plate 18 will be suspended on the water surface. This not only increases the contact area between the equipment and water and improves the stability of the equipment, but also prevents the mud from pouring out of the equipment during the mud injection, thereby avoiding environmental pollution. When the nail 17 is inserted into the underwater mud, it plays a role in firmly supporting the equipment, so that the equipment will not move or tilt due to the interference of water flow or other external factors.

[0034] Working principle: When using the equipment for drilling and grouting work in underwater construction, splice the connecting pipe 5 according to the depth of insertion into the water, install it on the installation pipe 1, insert the clamping ring 6 on the connecting pipe 5 into the clamping groove 3 opened inside the installation pipe 1, and slide the clamping block 7 inside the limiting groove 4 to limit the clamping ring 6. At this time, the clamping plate 1 8 on the connecting pipe 5 fits with the clamping plate 2 9 on the installation pipe 1. At this time, insert the fixing bolt 10 into the clamping plate 1 8 and the clamping plate 2 9 and rotate them to fix them. When the length is not enough, assemble the connecting pipe 5 again, and finally fix it. The tube 15 is connected to the connecting tube 5 at the bottom, and the clamping ring 6 on the fixing tube 15 is also inserted into the interior of the connecting tube 5, and finally fixed by the fixing bolt 10. After the assembly is completed, the threaded ring 19 inside the floating plate 18 is twisted in the threaded groove 2 opened inside the mounting tube 1, so that after the equipment is inserted into the water, the floating plate 18 is suspended on the water surface, which increases the contact area with the water and prevents the mud from pouring out of the equipment during the pouring and affecting the environment. Finally, the equipment is inserted into the water, and the ground nails 17 are inserted into the underwater soil to support the equipment, making the equipment more stable during the grouting.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
