>< ) Preparatory work before pile driving with spring vibrating hammer
With the further expansion of the scale of infrastructure construction in our country, especially the successive start of some large-scale foundation projects, a broad space has been provided for the hydraulic vibrating hammer, making it a Indispensable key equipment. For example, there are increasingly larger deep foundation pit projects, large-scale barrel pile construction and large-scale steel casing construction projects, soft foundation and rotary drilling rig construction projects, high-speed railways and basic roadbeds.
The preparation work before pile driving with vibratory hammer is as follows:
Carefully handle high-altitude ground and underground obstacles.
Conduct a comprehensive inspection of the buildings surrounding (within) the site. Carry out necessary treatment for dilapidated buildings.
Level and compact the entire area within and beyond the baseline of the building and the site within the driving route of the pile driver. On the movement route of the pile frame, the ground slope shall not be greater than %.
Repair transportation roads to make them flat and solid. Drainage should be smooth in the piling area and near the road.
Two level points need to be set at or near the piling site to level the site and check the depth of the piles. According to the axis control pile of the building, each pile position of the pile foundation is determined and marked. Before piling, the axis and pile position of the pile should be re-inspected.
After the pile driver enters the site, rail pads should be laid according to the construction sequence, the pile driver and equipment should be installed, the power supply and water source should be connected, and a test run should be carried out. Then move the machine to the starting point and put the pile in place. The pile frame should be vertical and stable.
Key points for vibratory hammer pile sinking construction:
The pile cap or pile clamp must clamp the top of the pile to avoid sliding, otherwise it will affect the pile sinking efficiency, damage the machine and tools, or cause safety accidents.
The vibration box of the top pulley of the pile frame and the longitudinal axis of the pile must be on the same vertical line.
If the sinking time is too long or the sinking fails, measures should be taken together with the design department.
Pile sinking should be carried out continuously to avoid too long a pause and difficulty in sinking.
