Step 1: After clearing the site, determine the positions of lighting, automatic water inlet valve and rainwater collection well in the courtyard according to the water and electricity layout.
Step 2: Manually dig 500-depth trenches to bury cables, water supply pipes and drainage pipes, and make indoor and outdoor control switches of power supply cables to ensure outdoor short circuit and not affect indoor power supply. The water supply pipe should be insulated, and a water inlet valve should be set at the junction between indoor and outdoor, and a drain valve should be set at the end. In winter, the inlet valve should be closed and the drain valve should be opened to ensure that there is no water in the pipeline. The drainage slope of the drainage pipe shall be made to ensure that there is no water in the hospital when the rainstorm comes.
Step 3: Set out the white mortar according to the position and specific size of the functional area in the construction drawing.
Step 4: Dig 200 deep by hand to pave foundation earthwork, 3: 7 lime soil cushion, mechanical plain soil compaction and concrete cushion.
Step 5: Level 40 thick dry hard ash, mix cement mortar, manually paste paving bricks, and install brick walls and wood products.
