The distribution of support and drainage methods for steel flower pipes, which have numerous small holes on their surface. These small holes are a crucial part of the steel flower pipe, containing many tiny cavities. They can be considered a very convenient passage for grouting the steel flower pipe. It is essential to ensure the smooth inflow and outflow of mud during the grouting and standard construction processes. It is common for the steel flower pipe to accurately inject mud during construction, laying a solid foundation and realizing the foundational work in the project construction.

1. Engineering geological survey

Prior to construction, a sampling survey and technical analysis of the engineering geological conditions should be conducted to obtain a geological survey analysis report. This will determine the properties of cohesive soil, silt, and fragmented rock bodies within the soil sections of the project. Concurrently, gather data on the groundwater level and precipitation in the slope sections to estimate the general drainage range and volume, thereby determining the distribution of steel pipe flowers used by the drainage department.

2. General grading of slopes

To facilitate the application of various technologies and ease of construction, after the geological survey and analysis are completed, the overall slope should be initially graded. Flatten out excessively uneven areas, and clear away loose soil on the slope surface, but do not overgrade, as this may affect the stability of the slope. Just ensure it doesn't excessively impact construction.
