[0022] A steel-structured waterfront walkway, walkway 1 extending along a revetment 6, includes a lower main support structure 2, an upper pedestrian structure 3, and display areas and railings 4 on both sides of the upper pedestrian structure 3. The lower main support structure 2 includes, from bottom to top, a steel sleeve 21, a reinforced concrete foundation 22, and steel columns 23. Inside the steel sleeve 21, from bottom to top, are arranged a layer of undisturbed soil 211, a compacted yellow clay layer 212, a rubble layer 213, and a rubble leveling layer 214. The lower part of the steel column 23 is embedded in the reinforced concrete foundation 22, and studs 231 are welded around the lower part of the steel column 23. The rubble layer 213 is embedded with... A reinforcing rib 215 is provided. The upper part of the reinforcing rib 215 is welded and fixed to the embedded part 222 located in the reinforced concrete foundation 22. The embedded part 222 includes an embedded plate and embedded ribs arranged perpendicular to the embedded plate. The embedded plate is exposed on the side wall of the reinforced concrete foundation 22. The lower part of the reinforcing rib 215 is inserted into the rubble layer 213, and the upper part is welded and fixed to the embedded plate. The reinforced concrete foundation 22 is a rectangular structure with embedded parts 222 on all four sides. Generally, the lower part of a crossbeam is connected to two sets of lower main support structures 2, which is equivalent to two rows of spaced steel columns 23 being constructed along the revetment. It is also supported by one set of lower main support structures 2. At this time, the crossbeam is relatively short.

[0023] The internal reinforcement 221 of the reinforced concrete foundation 22 is a single-layer surface reinforcement, which is a rectangular steel frame that is compatible with the volume of the reinforced concrete foundation 22. The studs 231 are built into the rectangular steel frame. The top surface of the steel column 23 is provided with an end plate. Ribs are welded between the end plate and the steel column 23 to strengthen the end plate.

[0024] The upper pedestrian structure 3 includes horizontal and vertical H-shaped steel main beams 31. The connection nodes of the horizontal and vertical H-shaped steel main beams 31 are T-shaped or cross-shaped. The ends of the T-shaped connection nodes are connected by straight connecting plates 32, and the ends of the cross-shaped connection nodes are connected by L-shaped connecting plates 33. The straight connecting plates 32 pass through the ends of the web of the vertical T-shaped main beam and are bolted to the web of the horizontal main beams on both sides. The L-shaped connecting plates 33 are located at the four corners of the cross-shaped connection joints and are connected to the web of the horizontal and vertical main beams by bolts.

[0025] The transverse H-beams of the main beams 31 are connected to the revetment 6 at their transverse ends, and the ends are connected to the concrete pads by expansion bolts. The upper pedestrian structure 3 also includes galvanized steel pipe secondary keels and plastic boards. The exhibition includes protective sheds, display sheds, display boards and partitions. The steel sleeve 21 is 500~700mm high, and the reinforced concrete foundation 22 is 500~600mm high, formed by pouring C30~50 impermeable concrete.

[0026] During the actual construction, a cofferdam should first be constructed using steel pipe cofferdam cylinders, waterproof cloth, templates, sandbags, etc. After the cofferdam is constructed, two water pumps should be used to pump out the water. After the water is pumped out, the positioning lines should be laid out at the bottom silt according to the design drawings, ensuring that the dimensions given in the drawings are strictly controlled and the position is not deviated. According to the layout line, the small sleeves should be manually tamped into the silt. Excess silt should be cleaned out inside the small sleeves, but it should be ensured that the base of the sleeves is still buried in the silt. After the silt is cleaned out, a 5 cm layer of loess (clay) should be laid on top and compacted. Rubble should be stacked in layers inside the small sleeves. The first layer needs to be compacted and filled with crushed stone. When stacking rubble, it is necessary to simultaneously install embedded reinforcing bars (the embedded bars must be installed inside the rubble), place the reinforcing cage, erect formwork, and pour concrete steel columns on top. The concrete is manually pushed in, and C40 concrete is used. Steel formwork is used. The embedded reinforcing bars at the bottom of the rubble must be inserted into the reinforcing cage. To prevent grout leakage from the steel formwork and pollution of the ecological environment, the following measures are taken to prevent grout leakage as appropriate:

[0027] Installing rubber strips: Adding rubber strips to the joints of the formwork can effectively prevent grout leakage. The rubber strips should have good elasticity and corrosion resistance. Choose appropriate thickness and width to ensure a tight fit with the formwork joints and prevent grout from flowing into the formwork. According to construction specifications, the thickness of the rubber strips is generally controlled between 5-10mm, and the width depends on the thickness of the formwork and the length of the joint.

[0028] Construction tape sealing: Applying construction tape to the outside of the formwork joints effectively prevents grout leakage. The construction tape should have good adhesion and weather resistance, adhering tightly to the formwork surface to prevent grout seepage. The adhesive strength of the construction tape should meet relevant standard requirements; appropriately widening the tape improves the sealing effect.

[0029] Applying an anti-seepage agent to the formwork: For formwork surfaces that require protection against grout leakage, applying an anti-seepage agent can effectively prevent grout penetration. The anti-seepage agent should have good permeability and adhesion, forming a sealing film on the formwork surface to prevent grout intrusion. The use of the anti-seepage agent must comply with relevant specifications, selecting an appropriate concentration and application method. After pouring the concrete, wait for it to reach its strength. Demolding can be carried out when the strength reaches 75%. An environmentally friendly and pollution-free release agent should be used for demolding.

[0030] Column fabrication and installation: The height of the top surface of the steel column should be measured and controlled according to the elevation control line drawn on the side of the revetment stone. Using measuring instruments such as a total station, the position and elevation of the column are determined according to the design drawings. At the processing plant, the steel square tube is cut, reinforced with welding ribs, and top support plate is processed according to the design requirements. After the steel column is processed, it is transported to the prefabrication plant.

[0031] Beam fabrication and installation: Transport the H-beams to the construction site by transport ship, use lifting equipment to hoist the beams to the top of the columns, adjust the position of the beams to align them with the center line of the columns; weld the connection between the beams and the columns; during the welding process, pay attention to controlling welding deformation, remove rust from the steel structure surface to achieve the specified rust removal grade, apply anti-corrosion coating, and ensure that the coating is uniform and the thickness meets the requirements.

[0032] Construction of wood-plastic composite panels: Once the foundation and steel structure meet design strength requirements, locate and install high-strength bolts and ordinary bolts at the corresponding positions on the beams and columns according to the drawings. Lay the wooden panels on the keel along a direction perpendicular to the revetment and secure them with round-head screws. Use round-head screws to secure decorative edge panels along the sides.

[0033] Railing installation: After the keel and wooden panels are completed, the railing installation begins. The railings are fully welded to the I-beams. The installation and welding of the protective shed, display shed, display panels, and partitions must meet the requirements, and are welded to the auxiliary beams or keel according to the drawings.

[0034] Material and construction requirements: The I-beams must meet the design specifications, with a surface free of oil, rust, pits, and bends. The platform must be flat during steel cutting, and measurements must be accurate and clear. Installation must be accurate and secure, without twisting, skewing, or deformation. Welds must be uniform in shape, well-formed, and free of cracks, weld beads, burn-through, or other defects. Parts not covered in this utility model are identical to or can be implemented using existing technology.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
