Although the old saying goes that there is no effect without comparison, this time it is often said that comparison is only to provide a reference basis for everyone, which is conducive to everyone's interpretation and understanding, and it is good to see the advantages clearly. However, it can also be better analyzed so that it will not take many corners.

Low headroom rotary drilling lessor introduces the operation steps of rotary drilling rig:

1. Before operation, the operator must do the corresponding specific content of class maintenance.

2. When starting, let the car engine idle for 2min and 5 minutes in winter, and check whether there is any problem with the dashboard and display lights. If no abnormality is found, normal drilling can be made.

3. During the actual operation period, blind charging is strictly prohibited. Increase the working pressure should be maintained at 300PA, and the rotating working pressure should be maintained at 100PA.

4. Pay attention to the nature of the guild's work from beginning to end. If the galvanized wire rope is distorted, check the connector and replace it if necessary.

5. During operation, all green lights (when the display light is not long on) should be stopped for inspection, find out the reason, and continue to work after maintenance.

6. When the soil throwing motor is applied, press the motor control button in the rocker first, and then delay the joystick to a high place after the output pressure rises to 15Pa. At the end, return to the rocker slowly before loosening the key. Do not suddenly release the motor control button when the joystick does not return.

Low headroom rotary drilling lessor introduces how many and how deep piles can rotary drilling drill drill?

1. Small server: drilling diameter is about 800mm, deep about 40m.

Slope protection piles applicable to building foundations; Some load-bearing structural piles; Piles less than 1m used for old city reconstruction and municipal road projects or for other purposes.

2. Small and medium-sized mechanical equipment: drilling diameter is about 1.5m, deep about 60m.

Highway bridge piles suitable for traffic safety facilities such as general highways and railway lines; load piles for large and medium-sized housing buildings, seaports and ports; urban viaducts or other suitable piles.

3. Server: drilling diameter is about 2.5m, deep 80m.

Highway bridge piles suitable for highways and railway tunnels; large-scale engineering multi-layer structural load foundation piles.

The drilling depth of the rotary drilling rig has high regulations on the torque of the rotary table of the rotary drilling rig, the bearing capacity of the automobile chassis, the lifting and hoisting technology of the main crane and other key components. The greater the torque of the rotary drilling rig, the heavier the pile.

It is a kind of industrial equipment suitable for foundation and foundation pile construction. It is usually suitable for layered construction of sandy soil, cohesive soil, material soil and other soils, and is widely used in different foundation engineering construction such as bored piles, continuous walls, foundation reinforcement and so on. The power of rotary drilling rig is generally 125 ~ 450kW, the driving force output torque is 120 ~ 400kN · m, the relatively large pile diameter can reach 1.5~4m, and the relatively large depth value is 60~90m, can meet a variety of large and medium-sized basic construction needs.
