Construction Methods of Several Common Bored Piles
Construction preparation includes: selection of drilling rigs, drilling tools, site layout and so on.
Leveling site → mud preparation → laying protection → laying work platform → installation of drilling rig and positioning → drilling into the hole → clear hole and check the hole quality → decentralized reinforcement cage → perfusion underwater concrete → pull out the protection tube → check the quality.
Impact drilling, punching drilling and rotary drilling into holes, etc. can be used mud wall construction method.
If the foundation of the installation of the drilling machine is unstable, the construction is easy to produce drilling machine tilt, pile tilt and pile eccentric and other adverse effects, so the installation of a solid foundation.
