Bock Silage Clamp Construction

The Bock UK silage clamp system is designed to be simple and quick to construct yet highly effective. Thirty years of German design have gone into making a clamp which will suit farmers as well as AD operators.

This starts with a site visit and a discussion on what you intend to store and how quickly you intend to feed out from the clamp, with achieving the best possible silage quality the priority, and ends with the supply of the panels for the clamps and ongoing supply of covers and services including silage advice.

2. Once the footprint  of the clamp and the clamp design has been agreed Bock Uk will produce detailed technical drawings and deliveries which will be managed by our team to meet your site requirements.

3. On site the first step is to clear the area the clamps are going to be constructed and begin the  building of the earth banks. For most sites the banks will be made from the aggregate dug out during the construction process of the AD plant or any other development on site.

5. A membrane should then be placed over the bank and wooden stakes drive into the bank, leaving .25m exposed between earth bank and the end of the stake. The end of the stakes are then cut to the exact 23 degree angle of the panel.

6. The patented Bock UK seating channel is then laid at the base of the bank on a thin mix of concrete

7. Once the channel is in place and secure the panels are placed in the channel and leant into the wall until they touch the end of the stake

9. The gap between the panel and the earth bank is then filled with free draining gravel and a rain water collection drain added on top of the panels.

10. Once the wall is complete the asphalt base of the silage clamp needs to be laid against the bottom of the panels tying the whole system into place.

11. Your clamp is now complete and can be used within 24 hours of the asphalt being laid. Total build times vary but as a rule of thumb panels can be placed at 50lm a day.
