3. When the pipe inclination is greater than 7°-12°, in addition to the horizontal pipe of 5 times length set at the front end of the inclined pipe, an exhaust valve should be provided at the upper end of the down pipe. During the pumping process, if there is a cavity in the inclined pipeline, the exhaust valve should be opened first until the inclined pipeline is filled with concrete, and when the exhaust valve overflows the mortar, the exhaust valve is closed and normal pumping is performed.
