1. The front end of the manual tube shall not be connected with the rubber conveying hose to avoid pulling and overturning.
2. The source of the manual nozzle shall not be buried by concrete piles.
3. When the scene of overturning appears, the cloth should be stopped immediately.
4. After finishing the pouring of the homework, the concrete distributor must stop cleaning the pipe of the concrete placing distributor. The inner wall of the pipe should be clean and there should be no residual concrete. 5. In high-rise construction, the wind shall not be greater than six.
6. Do not randomly increase or decrease the weight information in the weight box to prevent overturning.
7, often introspect whether the screws of each part of the fabric machine can be hooked, and whether the safety pins are strong, to prevent decoupling and overturning.
The common task working condition of the hydraulic placing placing boom machine is mostly with the boom up and the middle and small arms down. In the rising section of the pipeline (tower body and boom pipeline), the concrete in the pipeline is pushed to travel under the pumping pressure of the concrete pump. The concrete fills the ascending pipeline, and its flow rate fluctuates without segregation. In the lower part of the pipeline (middle and small arms), the flow rate of concrete is getting faster and faster due to the influence of gravity deceleration. Because the conveying flow of concrete in the lower section will not be changed, the decelerated concrete cannot overflow the conveying pipeline. The concrete is not "pushed" undulatingly in the lowering pipeline, but "rolled down" quickly. In the process of "rolling down", the concrete and the pipe wall will collide from time to time, and the aggregates will be separated from the slurry, so a kind of segregation occurs.
