KR50 small rotary drilling rig Nanjing dam reinforcement project video: https://v.qq.com/x/page/b0371bsucq6.html

Construction model: TYSIM Machinery KR50 small rotary drilling rig Construction strata: clay, silt layer

Drilling diameter: 1.1m Drilling depth: 9.5m

The total length of this project is about 4.2km. The clay impervious wall is punched and grasped by bushing holes. The hole spacing is 0.92m and the wall depth is 9.5m. The specific construction is to first drill a hole with a diameter of 1.1m and a depth of 9.5m with a TYSIM rotary drilling rig, and then backfill it with soil and tamping with a tamping machine. There is a hole every one meter. After a section of the dam is tamped, the place between the two holes Hit it again, and hit two more rows after setting the holes.

In the process of strengthening the embankment body, the major difficulty encountered is that the filling work surface of the embankment body construction is narrow, the soil layer is soft and has a certain slope, and some sections are operated under high-voltage lines. TYSIM Small Rotary Digging is handy for such projects. , KR50 has 14 piles in 8 hours a day, and KR80 has 16 piles in 8 hours a day. It is very suitable to complete this project.
