Description

Technical Field

[0001] The invention relates to the technical field of building engineering, in particular to an FRP tube profile sea sand quick-setting concrete composite column. Background Art

[0002] my country has a vast territory and a long coastline. In the vast ocean, there are rich marine resources. For example, in the civil construction industry, the available seawater, sea sand and coral reefs are huge, and the cost of sea transportation is lower than that of land transportation. However, the large amount of chloride ions in seawater can cause steel corrosion, which seriously affects the structural bearing capacity and durability of concrete. Although the engineering community has proposed anti-corrosion measures such as sea sand desalination, adding rust inhibitors, and steel bar treatment, the use of these methods is still limited due to technical and cost issues. In particular, for offshore island and reef projects that lack materials and machinery, overly complicated processing procedures and expensive costs are not realistic.

[0003] In order to fundamentally solve the problem of steel bar corrosion, material replacement is an effective method. Fiber reinforced composite materials (FRP) are a new type of high-performance structural material with light weight, high strength, corrosion resistance and strong designability. They can be made into cloth, plates, bars, grids, pipes and other forms combined with concrete. They can not only adapt to the harsh marine environment, but also use local materials, such as untreated seawater, sea sand and coral stones, which greatly reduces the transportation volume of raw materials. It is a suitable way for island and reef development.

[0004] At present, in the production and application process of FRP pipes, manufacturers usually manufacture them into specific standard lengths for the convenience of transportation. As a result, in actual use scenarios, when the required laying or construction length exceeds the specifications of a single pipe, multiple FRP pipes have to be spliced ​​to meet specific engineering requirements. However, what is troubling is that the existing FRP pipe splicing process is complicated and tedious, which is not only time-consuming and labor-intensive, but also has high requirements on the professional skills of operators. Workers need to accurately calibrate the docking angle and position of each pipe, and then use special connection accessories and sealing materials to fix them. Any slight mistake may lead to problems such as poor sealing and unstable structure at the splicing, which seriously affects the overall project quality and progress.

[0005] Therefore, it is necessary to provide a FRP tube profile sea sand quick-setting concrete composite column to solve the above technical problems. Summary of the invention
