[0045] Example
[0046] This embodiment provides a split-type caisson structure, referring to... Figure 1 As shown, it includes a lower caisson 1, an upper caisson 2, and a top plate 3. (Refer to...) Figure 5 As shown, the lower caisson 1 includes a lower outer wall 11 and partition walls 12, and the lower caisson 1 is an integral structure. Four lower outer walls 11 are arranged around each other to form a first rectangular space; multiple partition walls 12 are arranged horizontally and vertically within the first rectangular space, dividing it into multiple first compartments 13; connectors 14 are pre-embedded at the intersections of the partition walls 12. The compartment structure is a conventional design for caissons, which can improve internal strength and reduce the range of liquid sloshing.
[0047] Specifically, refer to Figure 1 and Figure 2 As shown, the upper caisson 2 includes an upper outer wall 21, a connecting column 22, and a rectangular compartment 23. The upper outer wall 21 is connected to the lower outer wall 11, and multiple upper outer walls 21 surround a second rectangular space. The connecting column 22 is connected to a connector 14, and the connecting column 22 includes a cylindrical surface. The rectangular compartment 23 is located within the second rectangular space and abuts against the upper part of the partition wall 12. The rectangular compartment 23 has a second compartment 231 aligned with the first compartment 13. That is, the rectangular compartments 23 correspond one-to-one with the first compartments 13, and the outer walls of adjacent rectangular compartments 23 abut against each other. The outer corner of the rectangular compartment 23 has an arc-shaped surface 232 that fits against the cylindrical surface of the connecting column 22.
[0048] Specifically, the top plate 3 abuts against the top of the upper caisson 2; the top plate 3 is provided with a first through hole to accommodate the connecting column 22, and the connecting column 22 is connected to a pressure plate 31 after passing through the first through hole, and the pressure plate 31 abuts against the top plate 3. The pressure plate 31 may be integrally formed with a nut, so that it is threadedly connected to the connecting column 22.
[0049] When assembling the caisson, the connecting pillars 22 can be installed first, followed by the installation of each rectangular compartment 23 using the connecting pillars 22 as positioning points. Finally, the upper outer wall 21 and the top plate 3 are installed. When dismantling the upper caisson 2, the top plate 3 can be removed first, followed by the disassembly and reassembly of each rectangular compartment 23 and the connecting pillars 22. At this time, retaining the upper outer wall 21 can resist water flow to a certain extent. Finally, the upper outer wall 21 is removed.
[0050] It should be noted that the rectangular compartment 23 at the edge abuts against the upper outer wall 21.
[0051] The modular caisson structure provided in this embodiment divides the upper caisson 2 into multiple rectangular compartments 23, an upper outer wall 21, and a top plate 3, among other unit structures, using compartments as units. When dismantling the upper caisson 2, each unit structure can be hoisted sequentially, reducing the volume and total amount of each hoisting operation and lowering the difficulty of hoisting. When assembling the upper caisson 2 structure, the rectangular compartments 23 can be assembled using the connecting column 22 as initial positioning, and the upper outer wall 21 and top plate 3 can be assembled last, without the need for additional positioning, making the operation convenient. The relative sealing between individual rectangular compartments 23 can also be improved.

The connecting steel bar 142 is connected to the bottom of the base 141. The connecting steel bar 142 is connected to the vertical steel bar inside the partition wall 12 via a connecting sleeve. The limiting plate 143 has a second through hole in its center. The outer periphery of the second through hole has through grooves 146 corresponding to the first locking grooves 145, and the through grooves 146 communicate with the second through hole. The limiting plate 143 is rotatably sleeved on the connecting column 22 and connected to the first locking tooth 144 by the first connecting bolt 147; the outer wall of the connecting column 22 is provided with a plurality of spaced second locking teeth 222; when the limiting plate 143 is rotated to the alignment of the through groove 146 and the first locking groove 145, the second locking teeth 222 are allowed to pass through and be inserted into the first locking groove 145; when the limiting plate 143 is rotated to the misalignment of the through groove 146 and the first locking groove 145, the second locking teeth 222 are prevented from disengaging from the first locking groove 145.

Finally, the limiting plate 143 is connected to the first retaining tooth 144 using the first connecting bolt 147.
[0054] By setting connecting steel bars 142 on the base and wing plate 148 and connecting the connecting steel bars 142 to the vertical steel bars of the partition wall 12, the connection reliability between the connecting column 22 and the partition wall 12 is improved; by rotating the limiting plate 143 to switch the alignment or misalignment of the through slot 146 and the first slot 145, the second locking tooth 222 can be accommodated to pass through or the second locking tooth 222 can be limited, which facilitates the installation and disassembly of the connecting column 22 and the connecting piece 14.
[0055] Specifically, the base 141 is surrounded by wing plates 148, and the bottom of the wing plates 148 is also connected to connecting steel bars 142. The wing plates 148 abut against the partition wall 12, further improving the connection reliability between the connector 14 and the partition wall 12, thereby further improving the connection reliability between the connecting column 22 and the partition wall 12.

This improves the waterproofness between the upper outer wall 21 and the lower outer wall 11.
[0058] Specifically, a sealant layer 121 is laid on top of the partition wall 12, and a square timber layer 122 is laid on top of the sealant layer 121. This improves the waterproofness between the rectangular compartment 23 and the partition wall 12, thereby preventing water seepage between different compartments.
[0059] Specifically, the upper outer wall 21 has a connecting part 212 on its side, and the connecting part 212 bends outward relative to the upper outer wall 21; the connecting parts 212 of two adjacent upper outer walls 21 fit together and are connected by a second connecting bolt 213.
[0060] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
