Instructions
Map out the plans for your tunnels. Draw detailed blueprints of the tunnel routes. Include the measurements of the tunnel as well as the depth. Write down the precise location in which you will dig your tunnels.
Contact your local and state government to inquire about digging regulations in your area. Most areas require permits to dig. In many cases, they ask you to supply them with copies of your blueprints, as well as your precise location information. Using this information, they may warn you of any possible dangers associated with location. They can also inform you of any underground wires, piping or other construction materials you may encounter.
Build the frame and support for the diaphragm of your tunnel. The construction materials depend on your soil composition, weather and geological conditions. Typically, the diaphragm is made from concrete. The construction of the diaphragm is similar in process as the construction of a basement.
Dig a trench in the desired location of your tunnel. Use shovels or a piece of heavy machinery, depending on the size of your tunnel. The trench serves as the core of your tunnel. Dig the trench the same width as you want your tunnel. Allow for enough room for the tunnel diaphragm to be lowered into it. The trench needs to be slightly deeper than the depth of your tunnel.
Embed the diaphragm into the trench. Build the earth up around and under the diaphragm as necessary, so it does not slip. Build the floor inside of the diaphragm, then secure the lid of the diaphragm. Concrete is good choice to seal the tunnel.
Cover the trench and tunnel with the dirt you removed from the trench. Plant grass seed over the top of the trench to conceal the excavation site.
