Abstract
Description
Technical Field
[0001] This application belongs to the field of seaport terminal technology, specifically relating to a surface structure of a seaport terminal. Background Technology
[0002] During construction, the surface structure of a harbor terminal is susceptible to strong winds and intense sunlight, and the precast slabs at the bottom are easily affected by external constraints, often resulting in long or network-like cracks in the surface concrete. Once these cracks continue to expand, chloride ions from the marine environment can penetrate into the internal steel reinforcement, causing rust expansion and severely affecting the durability of the surface structure.
[0003] Furthermore, in existing technologies, during the surface layer construction process, workers stepping on the reinforcing steel frame can cause it to sink and deform, especially in the middle, making it easy for workers to lose their balance. Therefore, there is an urgent need to propose a surface layer structure for harbor terminals that possesses good durability and addresses the problem of the reinforcing steel frame easily sinking and deforming during construction.

[0005] To solve the above-mentioned technical problems, this application provides the following technical solution:
[0006] This application proposes a surface structure for a seaport terminal, comprising at least a concrete layer and a reinforcement layer, wherein the concrete layer is disposed outside the reinforcement layer; the reinforcement layer comprises a first transverse stirrup, a second transverse stirrup, and longitudinal reinforcement, wherein the longitudinal reinforcement is arranged side by side along the horizontal and vertical directions to form at least two layers of reinforcement structure, wherein the first transverse stirrup and the second transverse stirrup are alternately disposed on the reinforcement structure; the length of the first transverse stirrup is longer than that of the second transverse stirrup, and the second transverse stirrup intersects with at least four of the longitudinal reinforcements.

[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0024] like Figures 1 to 3 As shown in one embodiment of this application, a surface structure for a harbor terminal includes at least: a concrete layer 4 and a reinforcement layer 5, wherein the concrete layer 4 is disposed outside the reinforcement layer 5; the reinforcement layer 5 includes: a first transverse stirrup 1, a second transverse stirrup 2, and longitudinal reinforcement 3, wherein the longitudinal reinforcement 3 is arranged side by side in the horizontal and vertical directions to form at least two layers of reinforcement structure, wherein the first transverse stirrup 1 and the second transverse stirrup 2 are alternately arranged on the reinforcement structure; the length of the first transverse stirrup 1 is longer than that of the second transverse stirrup 2, and the second transverse stirrup 2 intersects with at least four of the longitudinal reinforcement 3.
[0025] In this embodiment, the surface structure includes a concrete layer 4 and a reinforcement layer 5, with the concrete layer 4 enclosing the reinforcement layer 5. The reinforcement layer 5 consists of 50 longitudinal reinforcement bars 3 arranged horizontally in parallel to form a reinforcement structure, and another layer of reinforcement structure arranged vertically, forming a total of two reinforcement layers. First transverse stirrups 1 and second transverse stirrups 2 are alternately arranged on the two reinforcement layers, wherein the first transverse stirrup 1 is longer than the second transverse stirrup 2. The first transverse stirrup 1 intersects with the fifty longitudinal reinforcement bars 3 in the two reinforcement layers, and the second transverse stirrup 2 intersects with the six longitudinal reinforcement bars 3 in the two reinforcement layers. Those skilled in the art are motivated to adjust the number of longitudinal reinforcement bars 3 intersecting the first transverse stirrup 1 and the second transverse stirrup 2 according to actual conditions. Through the above arrangement, the first transverse stirrup 1 can connect the two reinforcement layers to form an overall skeleton, improving overall stability and load-bearing capacity; the design of the second transverse stirrup 2 can locally connect the two reinforcement layers, keeping the middle section stable. The combined design of the first transverse stirrup 1 and the second transverse stirrup 2 maintains the stability of the reinforcement skeleton. During construction, measures should be taken to prevent the middle section from sinking due to human foot traffic.
[0026] Preferably, the first transverse stirrup 1 is provided at the edge of the long side of the rib structure to ensure good integrity of the rib layer 5.
[0027] Specifically, the reinforcement layer 5 further includes: spacers, a plurality of spacers being disposed on the lower surface of the first transverse stirrup 1 and / or the second transverse stirrup 2 to support the reinforcement structure and facilitate the formation of the concrete layer 4.
[0028] Optionally, at least four pads are provided for each square meter of the projected area of the rib layer 5 to ensure that the rib layer 5 is subjected to balanced force.
[0029] Optionally, the reinforcement layer 5 further includes: binding wire, which is disposed at the intersection of the first transverse stirrup 1 and the longitudinal reinforcement 3; or, the binding wire is disposed at the intersection of the second transverse stirrup 2 and the longitudinal reinforcement 3. With the above arrangement, compared to the method of overlapping the first transverse stirrup 1 and the longitudinal reinforcement 3, or the method of overlapping the second transverse stirrup 2 and the longitudinal reinforcement 3, using binding wire to bind at the intersection makes the relative position of the two more stable and the strength greater.
[0030] Optionally, at least two binding wires are provided for each square meter of the projected area of the reinforcing layer 5 to ensure the stability of the reinforcing layer 5.
[0031] Specifically, the spacing between the two layers of the rib structure is 9cm to 11cm. A spacing higher than 11cm would be too sparse, resulting in insufficient strength, while a spacing lower than 9cm would be too dense, leading to excessive cost. In this embodiment, the spacing between the two layers of the rib structure is 10cm.
[0032] Specifically, the spacing between the first transverse stirrup 1 and the second transverse stirrup 2 is 9cm to 11cm. A spacing greater than 11cm would be too sparse, resulting in insufficient strength, while a spacing less than 9cm would be too dense, leading to excessive cost. In this embodiment, the spacing between the first transverse stirrup 1 and the second transverse stirrup 2 is 10cm.
[0033] Optionally, the first transverse stirrup 1, the second transverse stirrup 2, and / or the longitudinal reinforcement 3 are made of thermoplastic FRP (fiberglass reinforced plastic) reinforcement. FRP reinforcement is lightweight, corrosion-resistant, and has excellent mechanical properties. It also possesses insulating and non-magnetic properties, which can effectively resist corrosion in marine environments and ensure the durability of the surface structure in practical applications.
[0034] Optionally, the diameter of the first transverse stirrup 1, the second transverse stirrup 2, and / or the longitudinal reinforcement 3 is 10mm to 14mm. A diameter higher than 14mm would increase costs, while a diameter lower than 10mm would fail to ensure structural strength. In this embodiment, the diameter of the first transverse stirrup 1 and the second transverse stirrup 2 is 10mm, and the diameter of the longitudinal reinforcement 3 is 12mm.
[0035] Optionally, the concrete layer 4 is provided with the reinforcement layer 5 at a distance of 3cm to 4cm from its upper surface to improve the crack resistance of the surface structure.
[0036] In this embodiment, the construction method of the surface structure of the harbor terminal includes the following steps:
[0037] S1: Secure the second transverse stirrup 2 to the reinforcement structure; secure the first transverse stirrup 1 to the overall reinforcement structure; install binding wire and spacers;
[0038] S2: Use hoisting equipment to hoist and transport the reinforcement layer 5, and then manually install the reinforcement layer 5 in the designated position;
[0039] S3: Construction using high-durability concrete;
[0040] S4: Curing: After the concrete is poured and leveled, cover it with plastic film and the curing period should be 14 days.
