[0017] And mounting holes opened on the upper surface of the connector shaft.

[0018] Preferably, each of the plug shafts has a limiting shaft at its upper end to limit the threaded post inserted into the mounting hole.

[0019] Preferably, a connecting member is provided between two adjacent floating hulls, the connecting member comprising:

[0020] Mounting rings are fitted onto fixing rings in the two main bodies of the floating hulls, and the two mounting rings are respectively provided with a first connecting plate and a second connecting plate;

[0021] Multiple adjustment slots are provided on the upper surface of the first connecting plate;

[0026] Step 1: Based on the required external dimensions of the floating hull, calculate the buoyancy and thrust of the water, and then determine the number and distribution of the stabilizing interlocking structures.

[0027] Step 2: Install shaft cylinders on the main body of the floating vessel, and install adjusting components between the shaft cylinders and the main body of the floating vessel. Adjust the angle of the extension shafts by adjusting the adjusting components.

Detailed Implementation

[0044] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] Example 1

[0046] Please see Figure 1 - Figure 4 This application provides a simple floating hull for installing pipelines in the main arch ring of a cast-in-place arch bridge, comprising:

[0047] The floating vessel body 100 has multiple waist-shaped holes 101 along its perimeter to facilitate the installation of multiple stable plug-in structures 200.

[0048] The stable insertion structure 200 installed inside the waist-shaped hole 101 allows the extension length and vertical angle of the extension shaft 201 to be adjusted according to the depth of the underwater bearing layer, increasing the stability and safety of the floating vessel body 100. This provides a stable construction platform for the construction of pipelines for the water-crossing arch bridge. At the same time, it is simple to operate and easy to implement, providing a working surface for water-based installation work with higher efficiency, saving labor, and ensuring quality. The stable insertion structure 200 includes the extension shaft 201 installed at an angle in the waist-shaped hole 101, the shaft sleeve 202 sleeved on the extension shaft 201, and the adjusting component 203 for adjusting the tilt angle of the extension shaft 201.

[0049] In this embodiment, preferably, the adjusting member 203 for changing the angle of the shaft cylinder 202 includes:

[0050] Two fixing rings 2031 are fixed on the upper surface of the floating body 100 and located on both sides of the waist-shaped hole 101. A vertical plate 2032 is provided between the fixing rings 2031 and the floating body 100.

[0051] The rotating shaft 2033, which is installed between the outer surface of the shaft cylinder 202 and the vertical plate 2032, can be rotated to change the angle of the shaft cylinder 202, thereby changing the angle of the shaft 2011 installed in the shaft cylinder 202.

[0052] The arc-shaped sliding sleeve 2035, which is slidably sleeved on the fixed ring 2031, can slide along the fixed ring 2031 as the rotating shaft 2033 rotates.

[0053] In this embodiment, preferably, a fixing plate 2034 located inside the fixing ring 2031 is fixed on the rotating shaft 2033. The other end of the fixing plate 2034 is fixed to the outer surface of the arc-shaped sliding sleeve 2035. The inner surface of the arc-shaped sliding sleeve 2035 is provided with a notch for the upright plate 2032 to pass through, so that the arc-shaped sliding sleeve 2035 can slide along the fixing ring 2031. The curvature of the fixing ring 2031 is the same as the rotation curvature of the rotating shaft 2033.

[0054] In this embodiment, preferably, the surface of the arc-shaped sliding sleeve 2035 is screwed with a limiting bolt 2036 to limit its position, which can limit the position of the arc-shaped sliding sleeve 2035, thereby limiting the angle of the shaft cylinder 202.

[0055] In summary, during use, the angle of the shaft cylinder 202 is adjusted according to the depth of the floating hull 100 relative to the bottom bearing layer, causing the adjusting shaft cylinder 202 and the rotating shaft 2033 to rotate. This changes the angle between the central axis of the adjusting shaft cylinder 202 and the vertical direction. Simultaneously, the rotating shaft 2033 drives the fixing plate 2034 and the arc-shaped sliding sleeve 2035 to slide along the fixing ring 2031. When the angle of the shaft cylinder 202 is appropriate, the limiting bolt 2036 is rotated to fix the position of the arc-shaped sliding sleeve 2035, thereby securing the shaft cylinder 202. With the angle fixed and the shaft cylinder 202 at a suitable angle, the extension shaft 201 is then installed in the shaft cylinder 202, so that the extension shaft 201 has a suitable angle with the vertical direction, which facilitates the stable support when the extension shaft 201 is embedded in the bearing layer. Multiple extension shafts 201 extend outward and embed into the bottom bearing layer at the same time, maintaining stable support and fixation for the floating vessel body 100, making the floating vessel body 100 less prone to swaying, providing a stable platform and foundation for the construction of pipelines in the water-crossing arch bridge, and increasing construction safety and stability.

[0056] Example 2

[0057] Reference Figure 5 and Figure 6 This is the second embodiment of the present invention.

[0058] In this embodiment, preferably, the length of the extension shaft 201 can be adjusted according to the depth of the riverbed bearing layer to ensure that the extension shaft 201 can be embedded in the bearing layer, adapting to riverbed bearing layers of different depths, increasing the stability of the floating vessel body 100 during installation and use, and providing a stable foundation for the construction of pipelines in the water-crossing arch bridge. The extension shaft 201 inserted into the riverbed bearing layer includes:

[0059] Multiple plug-in shafts 2011 are spliced ​​together end to end. The outer surface of the plug-in shaft 2011 is provided with an external thread 2012 that mates with the shaft cylinder 202. The length of the external thread 2012 can be set as needed. The external thread 2012 mates with the shaft cylinder 202, which makes it easy for the plug-in shaft 2011 to rotate and move, and extend its length outward.

[0060] The threaded post 2013 installed at the lower end of the plug shaft 2011 is located at the bottom, which facilitates its mating with the mounting hole 2014 on the next plug shaft 2011. The threaded post 2013 on the bottommost plug shaft 2011 is easy to embed into the bottom bearing layer.

[0061] The mounting hole 2014 is provided on the upper surface of the plug shaft 2011. The inner surface of the mounting hole 2014 is provided with an internal thread to facilitate threaded connection with the threaded post 2013.

[0062] In this embodiment, preferably, each plug shaft 2011 has a limiting shaft 2015 at its upper end to limit the threaded post 2013 in the insertion mounting hole 2014, and the plug shaft 2011 has a through hole at its upper end for the limiting shaft 2015 to be inserted into, so that the limiting shaft 2015 will not protrude outside the plug shaft 2011 and will not affect the cooperation between the plug shaft 2011 and the shaft sleeve 202.

[0063] In summary, during use, based on the depth of the riverbed bearing layer, first splice an appropriate number of plug-in shafts 2011, allowing the threaded post 2013 of the previous plug-in shaft 2011 to engage with the mounting hole 2014 of the next plug-in shaft 2011. Then, use the limiting shaft 2015 to further limit the threaded post 2013, making it difficult for the two plug-in shafts 2011 to rotate, thus achieving a stable splicing of the two plug-in shafts 2011 and forming a relatively long shaft structure. Finally, attach the upper end of the shaft structure... Located in the shaft cylinder 202, and with the lower end of the shaft structure extending to the bottom bearing layer, the length is still insufficient. A plug-in shaft 2011 can be connected from the upper end of the shaft structure. After the plug-in connection is secure, the entire shaft structure is rotated. The external thread 2012 on the shaft structure engages with the shaft cylinder 202, and the shaft structure rotates downward until it is embedded in the bearing layer. When disassembling and assembling, the shaft structure can be disassembled by rotating it in the opposite direction. The entire shaft structure is easy to disassemble and assemble, achieving a stable installation of the floating vessel body 100.

[0064] Example 3

[0065] Reference Figure 7This is the third embodiment of the present invention.

[0066] In this embodiment, preferably, a connecting member 300 is provided between two adjacent floating vessel bodies 100. Using the connecting member 300, the splicing strength of the two adjacent floating vessel bodies 100 can be further increased after splicing, expanding the construction area and scope of the pipeline for the water-crossing arch bridge. Furthermore, the two adjacent floating vessel bodies 100 are easy to assemble and disassemble. The connecting member 300 includes:

[0067] An installation ring 301 is fitted onto a fixing ring 2031 in two floating bodies 100. A first connecting plate 302 and a second connecting plate 303 are respectively provided on the two installation rings 301, so that the first connecting plate 302 and the second connecting plate 303 are respectively installed on the two floating bodies 100.

[0068] Multiple adjustment slots 305 are provided on the upper surface of the first connecting plate 302, and the adjustment slots 305 are distributed along the length of the first connecting plate 302.

[0069] And a limiting plate 304 installed at the other end of the second connecting plate 303 and engaged with the adjusting slot 305.

[0070] In this embodiment, preferably, the surface of the mounting ring 301 is provided with a fixing post 306 that penetrates the first connecting plate 302. The first connecting plate 302 and the second connecting plate 303 can rotate around their respective fixing posts 306. The outer end of the fixing post 306 is provided with a limiting ring 307 that limits the first connecting plate 302. The limiting ring 307 is threadedly connected to the fixing post 306. When it contacts the first connecting plate 302, it can limit the first connecting plate 302 by frictional resistance. Similarly, the angle of the second connecting plate 303 can also be limited by the limiting ring 307.

[0071] In this embodiment, preferably, the length of the lower end of the limiting plate 304 extending out of the lower surface of the second connecting plate 303 matches the depth of the adjusting slot 305, so that the two can be easily engaged and connected.

[0072] In summary, during use, the two floating vessel bodies 100 are installed close together, allowing the first connecting plate 302 to be horizontal. The limiting ring 307 is rotated to press and limit the first connecting plate 302, fixing its position. Meanwhile, the second connecting plate 303 on the other floating vessel body 100 rotates downwards around the fixing post 306, causing the limiting plate 304 to rotate downwards and embed into the adjusting groove 305. The other limiting ring 307 is then rotated to limit and fix the position of the second connecting plate 303, thus maintaining a stable engagement between the second connecting plate 303 and the first connecting plate 302. This keeps the positions of the two floating vessel bodies 100 fixed and prevents them from easily detaching outwards.

[0073] Example 4

[0074] Combining the structures from Embodiments 1, 2, and 3, this embodiment presents a construction method for installing pipelines in the main arch ring of a cast-in-place water-crossing arch bridge, comprising the following steps:

[0075] Step 1: Based on the external dimensions of the required floating hull 100, calculate the buoyancy and thrust of the water body, and then determine the number and distribution of the stable plug-in structures 200.

[0076] Step 2: Install shaft cylinders 202 on the main body 100 of the floating vessel, and install adjusting components 203 between the shaft cylinders 202 and the main body 100 of the floating vessel. Adjust the angle of the extension shaft 201 by adjusting the adjusting components 203.

[0077] Step 3: Move the main body 100 of the floating vessel to the required working position. Starting from the middle of the long side of the main body 100 of the floating vessel, extend the length of the extension shaft 201 as needed, and extend the length of the extension shaft 201 into the water to the bearing layer by rotating the extension shaft 201.

[0078] Step 4: When the lower ends of all the extension shafts 201 reach the bearing layer, measure the flatness of the floating body 100 and adjust it by rotating the shaft cylinder 202 and the extension shafts 201. After the flatness adjustment is completed, stop rotating the extension shafts 201 to form a working surface.

[0079] Step 5: Pipeline installation work can only proceed after safety protection measures and scaffolding are in place on the work surface.

[0080] Step 6: After the construction is completed, first remove the scaffolding and safety protection used for construction, and finally, by re-fitting the shaft cylinder 202 with the extension shaft 201, the lower end of the extension shaft 201 is separated from the bearing layer, thereby releasing the constraint on the simple floating boat.

[0081] The above embodiments are only used to illustrate the technical methods of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of the present invention without departing from the spirit and scope of the technical methods of the present invention.
