Release time:
2021-07-29
The total length of this project is about 4.2km, and the clay impermeable wall is punched with sleeve holes, with a hole distance of 0.92m and a wall depth of 9.5m. The specific construction is to drill a hole with a diameter of 1.1m and a depth of 9.5m with TYSIM's rotary drilling machine, then backfill it with soil, tamp it with a tamping machine, one hole every one meter, punch the place between the two holes again after tamping a section of dam, and punch two rows after setting the holes.

In the process of embankment reinforcement, the major difficulties encountered are that the embankment construction and filling work surface is narrow, the soil ground is soft and has a certain slope, and some sections are operated under high-voltage lines. TYSIM small rotary excavation is handy for such projects. KR50 has 14 piles for 8 hours a day and KR80 has 16 piles for 8 hours a day, which is very suitable for completing the project.
