Abstract

An explosive storehouse comprising a head wall, a rear wall, two side walls and a single span arched roof;

• • wherein the head wall, rear wall, two side walls and the single span arched roof all include a metal lining located internally of the earth covered magazine explosive storehouse; and
  • wherein at least the two side walls, rear wall and the single span arched roof include shotcrete.

Claims

1. An explosive storehouse comprising:

a head wall;

a rear wall;

two side walls; and

a single span arched roof;

wherein the head wall, rear wall, two side walls and the single span arched roof all include a metal lining located internally of the earth covered magazine explosive storehouse; and

wherein at least the two side walls, rear wall and the single span arched roof include shotcrete.

2. The explosive storehouse as claimed in claim 1, wherein the two side walls are straight side walls.

3. The explosive storehouse as claimed in claim 1, wherein the head wall, a rear wall, two side walls and a single span arched roof include reinforcement bars.

4. The explosive storehouse as claimed in claim 1, wherein the side and rear walls and roof include shotcrete.

5. The explosive storehouse as claimed in claim 1, wherein a bracket connects the metal lining of each of the two side walls to the metal lining of the single span arched roof.

6. A method of forming an explosive storehouse including the steps of:

standing two straight metal linings opposite each other and supporting the two straight metal linings with props;

raising an arched internal single span metal lining to span between the two straight metal linings at the top edges of the two straight metal linings;

raising metal linings for head and rear walls at opposing ends of the two straight metal linings;

forming, pouring and setting a concrete floor;

placing internal propping between a connection between the arched internal single span metal lining and each of the two straight metal sides;

placing additional framework between the arched internal single span metal lining and the floor;

placing a reinforcement bar adjacent the two straight metal linings, the arched internal single span metal lining and for the head and rear walls;

placing formwork to the head wall;

pouring concrete into the formwork of the head wall to form a concrete head wall; and

shotcrete the formwork of the rear wall to form a shotcrete rear wall, shotcrete the two straight metal linings and shotcrete the arched internal single span metal lining.

7. The method of forming an explosive storehouse as claimed in claim 6, including a bracket between the arched internal single span metal lining and each of the two straight metal sides

8. The method of forming an explosive storehouse as claimed in claim 7, wherein the bracket is attached to the propping between the connection between the arched internal single span metal lining and each of the two straight metal linings during formation.

9. The method of forming an explosive storehouse as claimed in claim 6:

wherein the headwall is formed first after the floor is formed;

wherein the rear wall is shotcrete after the headwall is formed followed by shotcreting a six metre wide strip at the top of the arched internal single span metal lining from the rear wall to the head wall;

wherein concrete formation is halted for at least a day following the shotcreting the six metre strip; and

wherein after the at least one day half of one of the two straight metal lining is shotcrete followed by shotcreting half of the opposite of the two straight metal linings followed by shotcreting the remaining half of the initially shotcrete one of the two straight metal linings followed by shotcreting the remaining half of the opposite of the two straight metal linings.
