This Chinese people are now constructing house roofs with a unique technique. Instead of making the roof flat, they make it triangular, because they place mesh of steel bars over plastic sheets, then use a crane to pour concrete made from a mixture of sand cement stones and water into the hopper. Two people then pour it onto the roof from both sides, and the soft concrete flows into every fold of the steel bars. The workers level them and create a sloped roof. These Chinese company workers use unique method to construct drains by placing ready-made concrete block frames into holes with a JCB. One person simply ties a rope to the bucket and places two hooks on both sides below, then lowers them into the hole while holding them under pressure. Then they align and press the blocks against both sides of the empty concrete space, installing them one after another to build the drain which makes the water flow easier. These Chinese people give a 100-year durable idea for building road drains. Because with a smart technique, soft concrete made from a mixture of stone, sand, cement, and water is poured inside the excavator, and a drain is created according to the frame, and when people level it from the back, a strong drain construction is completed.
