Tunnel Triple
The Tunnel Triple is a great thing to crawl through or jump over. You will need large tyres along with 4” bolts and budget paint. There is no need for cement as you can compact the earth from the foundation around the tyres. Make sure you have at least 1.5 metres of space around the Tunnel.
Per Triple Tunnel Large tyres 4” bolts with 2 washers

How to build 1. Bolt 3 sets of 4 tyres together using 3 4” bolts per two tyres. 2. Cut the bolt threads off level with the nut and smoothen. 3. Dig a trench for each tunnel and bury the bottom third. Space them far enough
apart that the remaining tyre will sit well on top of all 3 tunnels. Cut drainage holes in the side wall of the remaining tyre. Place the tyre on top as shown above in the diagram. Use the remaining 3 bolts to bolt the tyre to the tunnels underneath. Cut the bolt threads off level with the nut and smoothen.
