Oxford Method Research Programme

Within the section on special drainage the following headings have been used.

1. Drainage to discharge acid contents.
2. Drainage through fire barriers.
3. Ventilation to system
4. Connection to outside building drainage.

Drainage to discharge acid

In the development of 6M Oxford Method laboratories were constructed. To produce a drainage system that dealt with the acid content glass was used to provide the dense material required. Joints were of a dense rubber material and the complete system laid in the ground under a concrete slab.

Drainage through fire barriers

Within the floor and ceiling zones, soil and rainwater pipes had to pass. In order to comply with the fire officer's requirements, the following drawing shows the measures taken to comply.

Ventilation to system

To vent the system and prevent a vacuum Durgo vents were included in the roof void. The means of support and positioning is shown on the following drawing.

The drawing shows the construction of 6M Oxford Method where brick outer skin had been introduced. Natural means of venting the system has been used as can be seen on the following drawing

Connection to Outside Building Drainage

As shown earlier in this manual drainage passed out of the building from the undercroft into an external manhole. In later development work 6M Oxford Method the undercroft had been dispensed with and soil and rainwater passed outside as shown on the following drawing.
