Description

Technical Field

[0001] The invention relates to the technical field of engineering construction, and in particular to a long-distance construction method and device under acidic geological conditions. Background Art

[0002] In the current engineering construction field, especially in areas with acidic geological conditions, the research and application of long-distance construction technology is particularly important. The soil and groundwater in these areas often contain high acid components, which puts higher requirements on the corrosion resistance of construction materials and equipment. In order to ensure the construction quality and long-term stability of the project, engineers and technicians must take a series of effective measures and methods.

[0003] Traditionally, long-distance construction under acidic geological conditions faces many challenges, such as strong rock corrosion, abundant groundwater, and easy landslides. These problems seriously affect the construction progress and safety. At present, in order to cope with the long-distance construction difficulties under acidic geological conditions, the industry usually takes the following measures: First, use anti-corrosion materials to extend the service life of the structure by improving the corrosion resistance of the materials; second, strengthen support and use more stable support structures to prevent surrounding rock collapse; third, optimize the drainage system and remove groundwater in time to reduce the impact on construction. Although these methods have alleviated the construction difficulty to a certain extent, the large-scale use of anti-corrosion materials and strengthened support will result in higher purchase and installation costs, longer maintenance time and other shortcomings.
