Abstract
PURPOSE: To enable to deliver in and carry construction materials even when workers are in a manlock, by a method wherein, in a pneumatic caison, a material lock part, which extends in a direction crossing a cylindrical manlock part at right angles, pierces through the cylindrical manlock part which extends in a horizontal axial direction.
CONSTITUTION: A shaft 2a of a cylindrical material lock part 2, which extends in a vertical axial direction, is caused to pierce through a center part of a manlock part 1 which extends in a horizontal direction and is formed in a long sideways cylinder. A worker opens a door 4 at a manlock stage 3 to enter thereinto. After an atomospheric pressure is regulated, the worker opens a lower hatch 10 and steps down along a ladder to enter into a shaft 12 and into a high-air pressure working chamber.
