MDL-135D, MDL-150D crawler deep foundation pit anchoring rig is an efficient drilling rig developed for anchoring, rotary jetting and precipitation based on domestic subways, high-rise buildings, airports, ground source heat pumps and other deep foundation pits. Its main features are as follows:
1. suitable for the following process construction
1.1 Anchoring can be applied to drill pipe drilling, casing drilling, and compound drilling of drill pipe casing.
1.2 Rotary spraying can be suitable for single, double, triple rotary spraying and other construction methods. By configuring different modules, it can be suitable for the following processes.
1.3 Precipitation in foundation pits.
1.4 Micro-filled piles.
1.5 Geothermal hole (water well) construction and survey.
1.6 static sounding (5T static sounding).
1.7 Dynamic sounding.
2. The torque and speed can be reasonably arranged according to actual needs. The stroke of the propulsion rack is 3.4 meters, and the compound drilling of 3 meters of drill pipe and casing can be performed. The corresponding torque gyrator can be configured according to different strata, which improves the Adaptability.
3. Equipped with crawler chassis, high-level rotating platform, large-diameter outrigger cylinder, 0.9-meter carriage, and orifice support device, which makes the displacement and positioning of the rig extremely convenient and stable and reliable during drilling.
4. Equipped with a clamping shackle, which makes the labor intensity of loading and unloading drill pipes and casings low and efficient.
5 R & D is equipped with corresponding drilling tools, which can meet the following construction processes:
5.1 Three-wing drill bit drilling, mud slag discharge, suitable for high-speed drilling of soil and sand layers.
5.2 Air DTH hammer drilling, air slagging. Applicable to the construction of rock layers and broken layers.
5.3 The bottom of the hole is drilled by hydraulic hammer, and the mud is discharged. It is suitable for the construction of stratums with large water content such as broken layers and sand layers.
5.4 Casing drilling.
5.5 Compound drilling of drill pipe and casing.
5.6 Single, double, triple rotary spray, fixed spray and swing spray processes.
