DETAILED DESCRIPTION

[0049] The technical solution of the present application is described in detail below in conjunction with specific implementations.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0053] like Figure 1 As shown, the first embodiment of the present application provides a dock wall structure, which includes a plurality of steel tube cylindrical structures 1. Figure 2-4As shown, each steel tube cylindrical structure 1 includes a plurality of first steel tubes 101 and an I-beam 102 connecting two adjacent first steel tubes 101. The plurality of first steel tubes 101 and the plurality of I-beams 102 surround a substantially circular steel tube cylindrical structure 1. The I-beam 102 has a first flange 1021 and a second flange 1022 that are substantially parallel to each other, and a web 1023 connecting the first flange 1021 and the second flange 1022, and the two ends of the first flange 1021 and the second flange 1022 are respectively connected to the two adjacent first steel tubes 101. At least the lower part of the steel tube cylindrical structure 1 is set in the soil, for example, 1 / 3-1 / 2 of the overall height of the steel tube cylindrical structure 1 is located in the soil.

[0054] The steel tube cylindrical structure 1 is a large diameter cylindrical structure, and its outer diameter is 15-30m (for example, 16m, 18m, 20m, 22m, 25m, 28m, etc.). The diameter of the first steel tube 101 is 400-600mm (for example, 420mm, 450mm, 480mm, 500mm, 520mm, 550mm, 580mm, etc.). The first steel tube 101 and the I-beam 102 can be fixedly connected by welding to form four roughly parallel vertical welds. In this embodiment, a double-layer circular structure is formed by the arrangement of the first steel tube 101 and the steel tube cylindrical structure 1, which stabilizes the entire steel tube cylindrical structure 1.

[0055] In another embodiment, the steel tube cylindrical structure 1 further includes a second steel tube 103 and a concrete cylinder 104. Wherein:

[0056] like Figure 2 and Figure 3 As shown, the diameter of the second steel pipe 103 is smaller than that of the first steel pipe 101, which is 200-300 mm (e.g., 220 mm, 250 mm, 280 mm, etc.), and the number is less than that of the first steel pipe 101, and the second steel pipe 103 is arranged at intervals on the steel pipe cylindrical structure 1, and is used to connect two adjacent first steel pipes 101 to replace the I-beam 102 there. The second steel pipe 103 has an extension 1031 that is longer than the first steel pipe 101 and the I-beam 102. The steel pipe cylindrical structure 1 has both the I-beam 102 and the second steel pipe 103; the center of the first steel pipe, the center of the second steel pipe and the center of the I-beam (web) are located on the same circumference of the steel pipe cylindrical structure 1.

[0057] like Figure 4As shown, the concrete cylinder 104 is annular, and its outer diameter is substantially equal to the outer diameter of the steel tube cylindrical structure 1, and its thickness is substantially equal to the diameter of the first steel tube 101; it is provided with a plurality of long holes 1041 that match the extension 1031 of the second steel tube along the circumferential direction, which can be through holes. The extension 1031 of the second steel tube is inserted into the long holes 1041 of the concrete cylinder, so that the concrete cylinder 104 is stably installed above the first steel tube 101 and the I-beam 102, forming the steel tube cylindrical structure 1.

[0058] When the second steel pipe 103 and the concrete cylinder 104 are provided, the first steel pipe 101 and the I-beam 102 of the steel pipe cylindrical structure 1 are driven into the soil, and the extension portion 1031 of the second steel pipe and the concrete cylinder 104 are located on the soil surface.

[0059] In this embodiment, the upper and lower parts of the steel tube cylindrical structure 1 are coaxially arranged and have approximately the same thickness. By arranging the concrete cylinder 104, the steel tube cylindrical structure 1 is a composite structure of steel tube and concrete. When the overall height is the same, the concrete cylinder is partially replaced, which can save the length of the first steel tube 101 and the I-beam 102, thereby saving metal steel; while ensuring the engineering strength, its economy is also improved.

[0060] like Figure 8 and Fig. 9 As shown, a conical plug 105 is provided at the bottom of the first steel pipe 101 , and the upper diameter of the plug 105 is slightly larger than the diameter of the first steel pipe 101 , thereby reducing resistance and facilitating the installation of the steel pipe cylindrical structure 1 .

[0061] like Figure 5-7 As shown, a cross beam 106 is provided on the upper part of the steel tube cylindrical structure 1, which is connected to the subsequent prefabricated plate 7 and is used to bear the force from above. When the steel tube cylindrical structure 1 has a second steel tube 103 and a concrete cylinder 104, the cross beam 106 is located on the upper part of the concrete cylinder 104. The cross beam 106 can be integrally formed with the steel tube cylindrical structure 1, which is convenient for transportation and installation.

[0062] like Figure 5-8 As shown, each steel tube cylindrical structure 1 is longitudinally provided with a first baffle 2 protruding outward; the first baffles 2 of two adjacent steel tube cylindrical structures 1 are arranged opposite to each other, and a post-cast strip 3 is formed therebetween. After the dock is drained, cement or concrete can be poured in the post-cast strip 3 to fill and seal the post-cast strip 3, so that each first baffle 2 forms a barrier layer together with the post-cast strip 3 to prevent external water from penetrating into the dock. The first baffle 2 can be arranged on the concrete cylinder 104 and arranged at the same height as the concrete cylinder 104, so that it can be integrally formed with the concrete cylinder 104.

[0063] like Figure 7As shown, in the dock wall structure, a steel sheet pile 5 is arranged between two adjacent steel tube cylindrical structures 1. The steel sheet pile 5 is roughly arc-shaped and arranged on the outside. The steel sheet pile 5 is driven into the soil and is located in the water, with its upper part exposed above the water surface, and can be used for temporary water stopping.

[0064] In the dock wall structure, backfill soil is backfilled inside the steel tube cylindrical structure 1 and between the outer side of the first baffle 2 and the steel sheet pile 5 to form a first backfill part 401 and a second backfill part 402, respectively. Figure 7 As shown, the dock wall structure is more stable. In the second backfill part 402, a water-stop curtain 6 is also arranged between two adjacent steel tube cylindrical structures 1. The water-stop curtain 6 is close to the steel sheet piles 5 and can be formed in the second backfill part 402 using cement mixing piles or rotary jet pile construction technology. Together with the barrier layer formed by the first baffle 2 and the steel sheet piles 5, the water-stop effect of the dock wall structure is further improved.

[0065] like Figure 7-10 As shown, a prefabricated plate 7 is laid on the top of the steel tube cylindrical structure 1. When the diameter of the steel tube cylindrical structure 1 is too large, the prefabricated plate 7 can be divided into a first prefabricated plate 701 on the inner side and a second prefabricated plate 702 on the outer side, which are spliced ​​together as a whole. A second baffle 703 is provided on the inner side of the first prefabricated plate 701, and the second baffle 703 extends longitudinally downward and is roughly parallel to the axial direction of the steel tube cylindrical structure 1, and is used to protect the upper part of the steel tube cylindrical structure 1.

[0066] Furthermore, if Fig. 9 As shown, a stopper 8 and a culvert 9 are provided above the prefabricated plate 7. The stopper 8 is provided above the second baffle 703 to limit the position of the culvert 9. The culvert 9 can be any culvert in the prior art, preferably in a rectangular shape, and is mainly used for laying electric wires, water pipes, etc. Backfill is performed above the prefabricated plate 7 and outside the culvert 9 to form a third backfill portion 10 that is roughly the same height as the culvert 9. A surface layer 11 is laid above the culvert 9 and the third backfill portion 10 to form the surface of the dock wall structure. A protruding wheel guard 12 is provided on the inner side of the surface layer 11 to prevent people or vehicles from falling from the surface layer 11.

[0067] The second embodiment of the present application provides a dock, such as Figure 1 As shown, it includes the dock wall structure described in any of the above embodiments, and the dock wall structure is respectively connected to two dock gate piers 13, and a dock gate 14 is arranged between the dock gate piers 13. A pump room 15 can also be arranged at the dock gate piers 13 for pumping and draining water in the dock.

The I-beam 102 has a first flange 1021 and a second flange 1022 substantially parallel to each other, and a web 1023 connecting the first flange 1021 and the second flange 1022, and the two ends of the first flange 1021 and the second flange 1022 are respectively connected to the two adjacent first steel tubes 101.
