The steel corrugated pipe culvert equipment is also known as a slope, that is, there is an angle between the direction of the metal corrugated pipe culvert and the construction road surface. At this time, the water outlet of the metal corrugated pipe culvert cannot be designed into the original circular shape. The pipeline should be designed as a slope corresponding to the angle of the road surface, so as to maintain the chaos and practicality of the metal bellows culvert. The anticorrosion treatment of the corrugated pipe culvert must not be lower than certain requirements to ensure that the corrugated pipe culvert has sufficient corrosion resistance within a certain period of time.
What are the requirements of corrugated culvert pipe for anti-corrosion treatment?
The emergence and increase of over-limit transportation. In the application of metal bellows elastic elements, in addition to the given load value, the effective direction and position of the given load must also be given. In the case of high working pressure, multi-layer stainless steel bellows are mostly used. For multi-layer stainless steel bellows, the number of layers and the thickness of a single layer should be selected fairly. According to the current bridge and transportation conditions, the carrying capacity of the bridge is not proportional to the passing vehicles.
The joints of the steel pipes are tightly embossed, which is firm and not tripped. After pouring on the site, it has a strong grip force with the concrete and forms a complete integration with the concrete, which enhances the seismic performance of the structure. The expansion of application fields brought about by the increasingly mature application technology, such as the internal pipe network, mining, warehousing, water conservancy measures and other fields of various industrial projects that have been widely used abroad. The third is that the cost of labor and traditional construction materials will increase. The competition of quality corrugated pipes has the upper hand; the fourth is the enhancement of environmental protection awareness and the advancement of soil and water conservation requirements, which will bring more extensive applications.
Before leaving the factory, it should be strictly in accordance with the processing and acceptance standards for steel corrugated culverts, and the necessary pre-assembly. Steel corrugated culvert pipes are assembled on site, and construction must be strictly in accordance with the requirements of the design and specifications for construction and installation of steel corrugated culvert pipes. After the corrugated steel sheet is transported to the construction site, it must be inspected block by block. Compared with the pontoon, it has also made great progress in terms of safety and carrying capacity. When installing the steel corrugated culvert, the splicing place must be cleaned up to ensure that the joints are tightly jointed and prevent open spaces.
After the application of steel corrugated pipe culverts, social and economic benefits have achieved relatively satisfactory results. However, the construction of stone arch culverts will slow down the progress of the project, and it is difficult to complete the project within the limited time limit. Therefore, in order not to extend the construction period and speed up the construction progress of the project, the owner partly requested to change the original design plan and replace it with a 0.8-5.2m steel corrugated pipe culvert, so as to ensure the quality of the construction and speed up the construction progress . The corrugated shape is selected from factors such as the use, function, use requirements, functions and manufacturing characteristics of various corrugated stainless steel bellows. Generally, most U-shaped corrugations are selected. Various expected load values for metal bellows and other elastic elements, such as concentrated force F, pressure p and moment M, etc.
