1 The operator of the concrete pump truck must be specially trained, familiar with the mechanical properties of the pump truck, master the operation method and precautions of the pump truck, seriously perform the safety duties of this post during production, and abide by the relevant safety regulations on site.
2 When concrete is conveyed by a concrete pump, its use and operation regulations should be followed. The pipe joints and safety valves must be intact, the pipe rack must be firm, and it must be separated from the structural template of the pumping part to form a self-supporting system. Pressure must be relieved during maintenance, and test delivery must be performed after maintenance.
3 When the concrete used has admixtures, the personnel mixing the admixtures must be handled carefully to prevent damage.
4 The parking area of the concrete pump truck shall be hardened, and the parking shall be stable and firm, and there shall be good drainage facilities to prevent collapse.
5 Conveyor pipes of concrete pump trucks must be carefully inspected before they are taken over for use. If there are cracks, leaks, serious wear on the pipe body, or damaged joints, etc., they should be repaired or discontinued. An accident occurred under high pressure.
6 When the pump pipe is connected, the erection must be reliable and firm. When the suspension is over, a steel pipe rack must be installed. To prevent the pumping process from swaying, it can be reinforced with anchor steel bars.
7 The connection of the concrete pump truck conveying pipe must use a good special bolt, and spare bolts and wearing parts should be used during construction.
8 When pumping concrete, no one should stand within 1 meter of the two sides of the pipe to prevent the pipe from swinging and hurting people; it is forbidden to stand within 30 meters in front of the pipe outlet to prevent air in the pump and bones pumped out when the pressure is high Expected to hurt people.
9 When installing and removing the duct next to the wall, the operator must observe the safety requirements for aerial work and fasten the seat belt (rope); after the duct is installed, it must be firmly connected to the wall to prevent falling.
10 When installing and removing the pump pipe, the labor should be sufficient, and the pipe cannot be hard-mounted or hard-disassembled. When the concrete is delivered with pressure water, the pressure water plug should be connected quickly and accurately. The personnel in the warehouse should pay attention to the spray at the outlet. Water washed over construction workers.
11 When removing a duct, one section must not be arbitrarily dismantled. The top-down and previous-after principles should be followed. The removed duct must not be thrown or thrown directly from a high place. After the duct is removed, it must be placed on a flat site and not stacked randomly. Shelves.
12 After disassembling the pump tube, it must be lifted to a level ground, flushed, stacked stably, and inspected. If damaged, it must be repaired in time.
13 During the operation of the pump truck, full-time personnel should be arranged to inspect the catheter frequently for looseness, and handle it at any time, and check the stability of the catheter fixed rack, bracket, and obvious damage to the catheter.
14 Before the concrete pump truck works, there must be perfect communication means at the pump truck site and in the concrete construction warehouse in order to carry out the construction safely.
