SA-180A crawler-type full hydraulic multifunctional high pressure rotary jet grouting drilling rig is a multifunctional geotechnical engineering drilling rig integrating rotary jetting, ترسيخ, and anti-floating anchor construction. It is widely used in subways, high-rise buildings, airports, hydropower stations, السكك الحديديه, dams and other deep foundation pits for soft soil foundation reinforcement treatment and anchoring construction. It is particularly suitable for urban deep foundation pit support, high-pressure jet grouting piles, anti-floating anchors and foundation grouting reinforcement engineering hole construction.

Multifunctional Geotechnical Engineering Drill Rig Main uses:

1. High-pressure rotary jet grouting reinforcement of soft soil foundation 2. High-pressure rotary jet pile water-stop curtain 3. Pilot hole construction 4. Anchor construction

SA-180A Multifunctional Jet Grouting Drilling Rig Suitable processes:

1. Three-wing drill bit drilling, mud slag removal. Suitable for high-speed drilling in soil layers and other strata.
2. Air down-the-hole hammer drilling, air slag removal. Suitable for rock layers and broken layers.
3. Bottom-hole hydraulic hammer drilling, mud slag removal. Suitable for construction of broken layers, sand and gravel layers and other strata with high water content.
4. Casing drilling.
5. Drill rod and casing composite drilling.
6. Single-tube, double-tube and triple-tube rotary jet grouting, directional jet grouting, swing jet grouting and other rotary jet grouting processes.

Anti-floating anchor construction:

SA-180A Rotary Jet Grouting Machine Main features:

A detachable 12-meter auxiliary tower is installed

1. During rotary grouting construction, it can replace elevated rotary grouting, reduce the number of drill tool disassembly times, and rotary grouting piles within 15 meters do not need to disassemble the drill rod, saving time and materials, and reducing quality risks. For rotary grouting piles exceeding 15 امتار, drilling or rotary grouting can be continued by adding drill rods.
2. During the construction of anti-floating anchor rods, the anchor rods can be hoisted to save the cost of the crane.
3. During the construction of inclined anchor cables, the auxiliary tower can be removed without affecting other functions of the drilling rig.
4. During the construction of short anchor rods, one rod can be used to the end, which saves time and efficiency, saves labor, and has low labor intensity.

Large through-hole rotary power head

1. The through-hole diameter is 92mm, and the 89 drill rod can pass smoothly. It can achieve triple rotary grouting construction and anchoring construction.
2. Ordinary 89 steel pipes can also be used for anchoring construction.
3. The hydraulic chuck structure allows for easy and free replacement of drilling tools.
4. The high-torque power head, combined with our enhancedrotaryjet grouting drilling tools, can be used in most strata for jet grouting construction without the need for a pilot hole, saving a lot of cost and time.

Tracked walking

1. A crawler chassis with a large ground pressure ratio is selected. Even on softer ground, it can walk freely.

Orifice guide device

1. The drilling tool can be easily disassembled during jet grouting construction, while achieving the construction angle and verticality.
2. During anchor construction, the force condition of the steel pipe can be improved, and the construction accuracy is high.
3. The rotating mechanism of the orifice can reduce the wear on the cobalt tool.
