How does a pile driver move on a construction site?

Relying on hydraulics, support the two side feet on the ground, hold the main body, and then slide the main body for a certain distance, and then drop the main body to complete a slide, or you can slide in the direction of 90 degrees vertically.

Rotary bored pile driver on construction.

How exactly do you drive piles:

1. Use the mud pump to bring out the drilled soil to form a pile hole, and then lower the reinforcement cage.

Pouring concrete.

2. The pile driver is composed of a pile hammer, a pile frame and ancillary equipment. The pile hammer is attached between two parallel vertical guide rods (commonly known as gantry) in front of the pile frame, and is hoisted with a lifting hook. The pile frame is a steel structure tower, and a winch is provided at its rear.

It is used to lift piles and pile hammers. There is a guide frame composed of two guide rods in front of the pile frame, which is used to control the piling direction, so that the pile can accurately penetrate into the formation according to the design orientation. The basic technical parameters of the pile driver are the weight of the impact part, the kinetic energy of the impact and the frequency of the impact.

According to the power of the movement, the pile hammer can be divided into drop hammer, steam hammer, diesel hammer, hydraulic hammer, etc.

The general walking pile driver first uses 4 hydraulic cylinders (outriggers) to jack up the pile driver, stretches out the track at the bottom of the pile driver, retracts the outriggers to drop the pile driver, and then the pile driver advances along the track stretched out before by the thrust of the hydraulic ram at the top of the track, and the work efficiency is low. The crawler pile driver produced by our company now moves flexibly and is convenient in place, and the electrical and hydraulic all adopt centralized control, which is very convenient to operate.

Installation Operating Procedures.

1. The operator of the pile driver must be familiar with the structure, performance, operation essentials and safety precautions of the machine, and can only operate separately after passing the examination and obtaining the certificate.

Second, the operator must concentrate on the operation. Do not talk, laugh, fight, or make trouble with unrelated personnel, and do not smoke or eat food during operation.

3. Strictly abide by the relevant maintenance regulations of the pile driver, conscientiously do a good job of maintenance at all levels, and ensure that the pile driver is always in good condition. And pay attention to reasonable use and correct operation.

Fourth, before the pile driver work, the following preparations should be made:

1. Learn about the construction conditions and tasks from the construction personnel, as well as the problems found in the construction and the matters that should be paid attention to in this class.

2. Adjust the position of the variable speed gear of the pile driver according to the vibration force required by the construction personnel.

3. Check whether the insulation of cables and wires is good. Check that the controller contacts are good and the boundaries are correct.

4. Check whether the voltage of the power supply meets the requirements.

5. Lubricate and maintain each part according to the daily maintenance items.

5. Safety precautions for pile drivers at work:

1. When the pile driver is working, there should be a special person to command. Commanders and operators should check each other's signals before working. Close cooperation should be done in the work.

2. At the beginning, use the electric bell or other means to send a signal to notify the surrounding people to leave.

3. The plane of the pile driver and the pile cap, the pile cap and the pipe string (or pile) should be flattened, the connecting bolts should be tightened, and whether there is looseness should be checked frequently.

4. The start of the pile driver should be accelerated from low speed to high speed.

5. The pile driver should pay close attention to the indication of current and voltage on the control panel during work. If abnormal noise or other abnormal conditions are found, the machine should be stopped immediately for inspection.

6. Always check the bearing temperature and whether the bearing cover screws are loose, and strictly check whether the eccentric iron coupling screws are loose to prevent accidents.

7. When sinking, it is strictly forbidden to stand around the pipe string (or pile).

8. When the pile driver cooperates with water injection and mud suction, it should contact the relevant personnel in advance and take care of each other in the work.

9. When connecting the pipe string or pile and installing the pile cap, the staff must wear a safety belt.

10. In the process of sinking, it is strictly forbidden to carry out mechanical maintenance and maintenance work.

6. After the pile driver stops working, the power supply should be cut off immediately, and the pile driver and motor should be inspected and maintained.

7. The pile driver has been out of service for a long time and should be stored in storage, the motor should be protected from moisture, and the instrument on the control panel should be removed and packed for safekeeping.
