4.in the process of concrete transport, the two sides should assign someone to be in charge of contact work, obey the command of the scene, the use of pumping or other means of transport, must be in the early pre cast concrete. Pumping concrete working gap should not exceed 15min, in order to reduce the plugging pipe plugging phenomenon. Artificial transportation of concrete to control the time, taking into account the delivery channel and irrigation methods.

5.concrete pump pipe laying should press the pump to send program arrangement, pump pipe laying should be straight, bend should be slow down, interface must be closely, firm fixation, before pumping must with cement mortar (concrete and the same proportion) lubrication pump pipe inner wall.
