We all know that pump truck pipelines need to be moistened. Failure to moisturize the pipes will cause blockage. Traditional pipe moistening uses cement mortar. This kind of pipe moistening has certain defects and requires tedious steps. For example, the mortar The mixing, transportation, use, and mortar processing processes take time and increase consumables. The subsequent processing of cement mortar is also a problem. Nowadays, the new pump truck lubrication material is a white powder lubrication agent. It melts in time when it comes into contact with water. The pipes can be lubrication by stirring slightly in the water. The water after lubrication does not need to be treated, because the lubricant itself is an environmentally friendly material. No harm will be done to the land.
Pump trucks are most widely used in high-speed rail and civil construction. Many high-speed rail lines are composed of bridges. Bridges are inseparable from cement piers. It is very convenient to use pump trucks to pour bridge piers. There is no need for ground pumps. When it comes to laying pipelines, the construction efficiency is very high. High-speed rail is generally constructed in remote and remote areas. The transportation of concrete will be affected by some natural environmental factors, making transportation extremely difficult! But through human wisdom, no matter how difficult and dangerous the project is, it can't be difficult for great human beings.
The pump truck must lubricate the pipes before each start of work to ensure that the pipes are not blocked when concrete is pumped. When the pump truck was first launched on the market, there was no process of lubrication of the pump truck pipeline. The pipes of the pump truck are made of high-temperature cast iron. The high-temperature cast iron material is extremely water-absorbent. If concrete is pumped directly without lubrication, the pump pipe will absorb a large part of the water, causing the concrete to lose too much water. The slump increases rapidly, making the fluidity of the concrete worse, and the pipe clogging problem is extremely serious. In order to solve this problem, the engineers tried many methods but could not solve it. In the end, the engineers used cement sand paddles to moisten the pipes. The effect was still good, but the effect was slightly worse when used on the ground pump! There are many disadvantages of cement sand paddle pipe moistening, such as high pipe maintenance cost, inconvenience, non-environmental protection, waste of resources, etc. Cement sand paddle cannot be poured directly into the structure because its strength does not meet the standards of concrete. If it is poured directly into the building structure, it will easily cause project quality problems! If there has been such a "dry" construction unit, think twice!
In countries with relatively developed economies in Europe, they have realized the importance of environmental protection early on. They have not used cement sand paddles for pipe lubrication for a long time. What replaces cement sand paddle lubrication is a new type of pipe lubrication material. It is called "lubricating agent". The birth of lubricating agent can be said to be a milestone, that is, it has achieved the lubricating effect of cement sand paddle, and is even better than cement sand paddle. The use effect is very significant, environmentally friendly, efficient and save money. , time-saving, labor-saving and other advantages are all realized in the "moisturizing agent". In China, companies such as China High-Speed Railway, China Construction and some well-known construction companies have also used "lubricants" early
