Description

Small pile structure improvement

This creation is a small piling body, especially a small piling structure improvement.

According to the current piling equipment used in foundation construction projects, it mainly includes: spiral pile driver, diesel concrete pile driver, plug-in machine, vibratory pile hammer, rotary drilling rig, down-the-hole drilling rig, forward and reverse ring drilling rig, impact drilling rig and gravel Pile machines, etc., in which the vibrating pile hammer is mainly a kind of equipment that generates a powerful exciting force to drive an object into the ground after being energized. The motor drives the pair of eccentric blocks to rotate in opposite directions, so that the lateral centrifugal forces generated by them cancel each other out, and the vertical centrifugal forces are superimposed on each other. The high-speed rotation of the eccentric wheel causes the gear box to generate vertical up and down vibrations, thereby achieving the purpose of sinking piles. .

The vibratory pile hammer is a pile foundation construction machine used in construction engineering and is used for the construction of concrete pouring piles. After supporting with the pile frame, the concrete can be piled, the concrete expanded pile (garlic head pile), the lime pile, the sand pile, the gravel pile; after the pile clamper is installed, the concrete precast pile and various steel piles can be sunk . The best application of vibratory pile hammers is roads, bridges, airports, buildings, etc. Among them, the vibratory pile hammer is provided with a piling body for buffering the vibration in the upper and lower shear directions. The existing piling body has a straight structure in the deformation portion (rubber) of the middle section, so the overall strain value is poor and it is not resistant to use, so it must be normal.
