Rotary Heads for Pile Rigs
EURODRILL rotary heads for pile rigs are designed for high power consumption and a long durability. These rotary heads operate for many years in different applications worldwide.
Advantages
- Compact design requires only small room
- Strong axial bearing system of the main shaft to ensure high pull- and push forces
- Central supply of the mechanical components and bearings via continuous delivery of a lubrication pump
- Compatible to drill rigs of all manufacturers for different applications and requirements
In front of the wall Drilling Systems
EURODRILL VDW drilling systems are designed to produce secant pile walls and others. Due to the counterclockwise operation of auger and casing an enormous drilling progress as well as a great precision can be achieved.
Advantages
- Compact design requires only small room and optimal use of existing narrow rooms to produce secant pile walls directly in front of an existing wall
- Integrated sliding cylinder for relative adjustment of the casing to the hollow auger
- Extremely low-emission and vibration-free drilling method, especially suitable for the use in the city centre
Production of a bored (secant) pile wall
A distinction is made between the following types of execution
- overlapping bored pile wall
- tangent bored pile wall
- resolved bored pile wall without intermediate arch
- resolved bored pile wall with intermediate arch
Step 1 - Make a template
Styrofoam blanks are lined up and poured into concrete.The template ensures a safe and uniform positioning for primary and secondary piles.The respective styrofoam insert will be bored out later in the process.
Step 2 – Drilling of the primary piles
Aligning the drill sting over the template and drilling of the primary piles. Simultaneous concreting of the pile at respective extraction of the drill string. Emptying the drill string after each drilling or concreting process.
Step 3 – Drilling of the secondary piles
Aligning the drill string over the template and drilling of the primary piles. Simultaneous concreting of the pile at respective extraction of the drill string. Emptying the drill string after each drilling or concreting process. Introduction of the reinforcement in the freshly concreted pile.
