Description
Technical Field
The invention belongs to the field of water transport engineering, and particularly relates to a steel hoop supporting structure for an assembled pile foundation wharf and a construction method thereof, which can give consideration to both temporary supporting and pile stabilizing functions.
Background
At present, the construction and construction of the domestic hydraulic wharf are still labor-intensive industrial models, taking the construction of the traditional high-pile wharf as an example, a large amount of labor force needs to be invested on site from pile sinking, cast-in-place beams to component installation and the like, and meanwhile, large-scale water ship equipment needs to be used, so the construction and construction of the traditional hydraulic wharf face the following three serious problems:
1) the field workload of the traditional wharf is heavy, the investment of labor force and large-scale equipment is more, and the field construction difficulty is very high due to severe weather and unfavorable tide levels.
2) The labor shortage and the aging trend of the age structure of workers are realized, and the contradiction between the high standard and the high quality of construction and the shortage of the number and the quality of local professional workers is very prominent.
3) The informatization development of construction and construction is lagged, the technological progress cannot effectively improve the productivity level of enterprises, and the profit margin of the enterprises is decreasing year by year.
If the existing construction and construction process is not reformed, the development of future port construction business of China is bound to be restricted, the national guidance suggestion is to vigorously research and develop the assembly type pile foundation wharf, the assembly rate of the components is up to more than 85 percent and the volume assembly rate is not less than 50 percent by developing the assembly type pile foundation wharf, the field construction workload can be greatly reduced, the construction and construction efficiency of the wharf is improved, and the adverse effect of tidal water and weather on the field construction is reduced, the construction characteristics of the upper structure of the assembly type pile foundation are that the lightweight component installation and the node pouring are carried out, compared with the traditional high pile wharf, the construction of structures such as a large amount of cast-in-place beams or pile caps and the like is saved, but the first layer component installation and the node pouring of the upper structure of the wharf still need to be provided with a temporary support structure, and simultaneously, the sunk pile foundations, therefore, the installation of the temporary support structure and the pile stabilizing structure of the fabricated pile foundation wharf is the first step of constructing the superstructure and is also a key ring for the research of construction technology.
The steel anchor ear used in the traditional high-pile wharf only has a supporting function, and can meet the requirements of component installation, concrete pouring and pile stabilization only by matching with the use of profile steel, wood grids and a bottom template, wherein the pile stabilization is realized by erecting paired bearing profile steel on the steel anchor ear and clamping and connecting the pile foundations of a bent frame into a whole so as to ensure that the pile foundations are kept stable under the disturbance of water flow and waves; because the bottom template, the wood grating, the bearing section steel, the steel hoop and other support systems are mutually independent components, the traditional process can not realize the integrated installation of the components.
