The invention relates to the field of engineering machinery, and discloses a pumping control method and apparatus, a material distribution method and apparatus as well as a distribution device. The pumping control method includes: calculating an initialized pumping speed; controlling a distribution device to pump at the initialized pumping speed; and dynamically adjusting the pumping speed of the distribution device in real time according to a completed real-time distribution volume and real-time distribution time during the pumping of the distribution device until the real-time distribution volume is a desired distribution volume. Therefore, the accuracy of a final distribution volume is improved. The distribution method includes: controlling a distribution device to perform distribution at a to-be-distributed location in a preset distribution area; and after distribution at the to-be-distributed location is completed, determining a next to-be-distributed location in the preset distribution area and performing distribution at the next to-be-distributed location until distribution at each to-be-distributed location in the preset distribution area is completed. Therefore, automatic distribution is achieved.

The second supports include: shafts; and hinges disposed between the shafts and the first supports to tilt the shafts toward the first supports to transition from the expanded position to the compact position and to raise the shafts from the first supports to transition from the compact position to the expanded position.

An automatic leveling system to maintain a 3D printer for building construction components in a substantially horizontal orientation includes: a support structure to support on a ground surface at least two columns each being supportable at a variable distance above the ground surface; a signal generator to generate a rotatable signal in a substantially horizontal plane; and sensors mounted on the columns to detect the rotatable signal. The variable distances are adjustable based on the detection of the rotatable signal by the sensors.

A method of manufacturing a tower structure includes providing an additive printing device having at least one printer head atop a support surface. The method also includes positioning a pre-fabricated component adjacent to the support surface. The pre-fabricated component is constructed of a composite material reinforced with a plurality of reinforcement members. Further, portions of the plurality of reinforcement members protrude from the composite material. Moreover, the method includes printing and depositing, via the at least one printer head, a cementitious material onto the support surface to build up the tower structure layer by layer around the pre-fabricated component. Thus, the portions of the plurality of reinforcement members that protrude from the composite material reinforce the cementitious material around the pre-fabricated component.
