The present disclosure provides a block coupler for connecting block to block for septic tank and water treatment facility. The block coupler comprises a body having a flow path therein; an inflow part having an inflow hole formed on one side of the longitudinal ends of the body so as to communicate with the flow path; an outflow part having an outflow hole formed on the other side of the longitudinal ends of the body having the inflow part so as to communicate with the flow path; and a connecting part provided at the outer end of the body having the inflow part so as to prevent the body coupled to the block from being separated.

A method for joining shipping containers together to create a modular structure includes providing a first shipping container and a second shipping container; removing a wall of the side of the first shipper container to create a first opening; removing a wall of the side of the second shipping container to create a second opening; positioning the first opening adjacent and opposite to the second opening; aligning the first opening with the second opening; after the aligning, securing the first shipping container to the second shipping container to create the modular structure; and securing an inner flashing around an inner periphery of the first opening.

A mobile tower system includes a steel shipping container. A tower structure is moveable between a substantially horizontal travel position and a substantially vertical operational position. A connection member is fixed to a lower portion of the tower structure and moveably coupled to a channel disposed in a horizontal member removeably attached to a vertical frame attached to a back wall of the steel shipping container. When the tower structure is displaced from the substantially horizontal travel position to the substantially vertical operational position, the connection member and the tower structure are linearly displaced together along the channel toward the back wall and the tower structure is pivotably displaced about the connection member, such that the upper portion of the tower structure is displaced through an opening disposed in a roof of the steel shipping container proximate a back wall of the steel shipping container.

A modular container is provided having a base. A plurality of panels is coupled to the base to form an enclosure having an internal volume. The plurality of panels substantially defines an outer perimeter, and substantially defines a top circumferential edge of the modular container. At least one door provides access to the internal volume. A roof having a shoebox flange is coupled to the plurality of panels. The shoebox flange circumscribes the roof and defines the outer perimeter of the roof. The shoebox flange fits over the top circumferential edge. The roof comprises a plurality of individual roof panels that are fastenable together. The modular container, when in a disassembled and flat-packed state, fits at least one of horizontally and vertically in an ISO container.

A shipping container connector includes a first latch unit, a second latch unit and a pulling rope unit. The first latch unit has a first body member, a first latch portion. The first body member has two side walls cooperatively defining a mounting space. One of the side walls has a threading hole. The second latch unit is disposed in the mounting space, and includes a second body member, and a spring member. The pulling rope unit extends through the threading hole, and has an end fixed to the second latch unit, and an opposite end disposed outside of the threading hole. When the pulling rope unit is pulled, the second latch unit is driven to move relative to the first latch unit from a locked position to a released position, where the spring member accumulates a biasing force for biasing the second latch unit towards the locked position.
