Having a pipe blocked by a pump truck is a very "troublesome" thing! In mild cases, it can be solved by reverse pumping; in severe cases, the pump tube is scrapped. What are the factors that cause the pump truck to become blocked? When it comes to effective methods, the most important thing is to focus on prevention and reduce the chance of pipe blockage. The editor summarizes the following points through industry experience, hoping to be helpful to everyone.
First: Care and maintenance of pumping equipment
It is necessary to perform routine and in-depth maintenance on the equipment in accordance with the maintenance manual of the pumping equipment manufacturer. Do not allow the equipment to be used during construction. Keep your equipment in good condition at all times. If minor problems occur in the equipment, if timely maintenance is not carried out, the damage to the equipment will increase over time. The maintenance of pumping equipment can range from a few thousand to tens of thousands, which will cost money and delay time. Time is the era of life, and I really can't afford it!
Second: Control of concrete slump
Strictly speaking, self-mixed concrete is not suitable for pumping by pump trucks. Self-mixing of concrete basically occurs in relatively remote areas where there are no commercial concrete mixing stations. Self-mixed concrete does not accurately control the water-cement ratio and does not add additives. The mixed concrete has insufficient workability and fluidity. If it is pumped by a pump truck, it will easily cause segregation. Concrete segregation is the main cause of pipe blockage. Occasionally pipe blockage may occur during the pumping process of Shang Concrete. Most of them occur on the ground pump. Slump control of Shang Concrete is also very important. Through his many years of experience, the collapse of the first truck of concrete was The slump should be lower than the slump specified by the construction unit (in layman's terms, it means the mixing should be thinner). If conditions do not allow, the master who operates the pump truck can add some clean water to the tank truck at the construction site. The tanker starts pumping only after the tanker is stirred evenly.
Third: Moisturizing and flushing pipes
Moisturizing and flushing pipes may seem like a simple process, but it plays a vital role in whether the entire pumping process is smooth. First, let’s talk about flushing the pipelines. Many workers were exhausted after the construction. They cleaned the pump pipes half-heartedly and did not flush them thoroughly, resulting in residual concrete in the pipelines. Over time, the concrete is likely to solidify, which will form the next time the construction is done. Because of artificial obstacles, it is very necessary to thoroughly clean the pipeline after each completion. Lubricating the pipe is an important guarantee to ensure smooth opening every time the construction is started. The pipe will be very wet when pumping for the first time. If the pipe is not lubricated, a large part of the moisture in the concrete will be sucked away by the iron pipe during the pumping process. If there is a lack of moisture in the concrete, the fluidity of the concrete will be poor and pipe blockage will occur, so pipe lubrication is an essential task for every construction. I would like to recommend a pump truck lubricating agent with a very good lubricating effect. It is produced by Shenzhen Yuanda Materials. You can search the words Yuanda lubricating agent on Baidu. In the event of any pipe blocking incident, sufficient preparations can be made in advance to minimize the pipe blocking incident. </p
