  • The concrete pump truck is a kind of concrete pump commonly used at present. When the pumping operation is performed, the concrete pump truck usually needs to expand all the booms, and through the high-pressure action of the pumping system, the concrete is pumped to the use site by the boom pipes. If the concrete pump truck needs to be pumped at close range, how can it be more economical? In response to this problem, we visited relevant experts. Experts point out: When the concrete pump truck pumps concrete for high-rise or large span ... Details >>
  • Concrete pumps have a history of nearly one hundred years. In 1907, France began to study concrete pumps, and some people obtained patents. Since then, some people have obtained patent rights in the United States in 1913 and manufactured the first concrete pump, but it was put on hold after trial operation and has not been applied. In 1927, Feliz Heier of France designed and manufactured a concrete pump, which was successfully used for the first time. By 1930, Germany had manufactured vertical single-cylinder ball valve pistons ... Details >>

  • In the construction project, we found that after the construction, exposed bars were formed on the exterior of the construction. Generally, the main reasons for this are: 1. After the steel bar was completed on the repair model board, the steel bar was deformed and displaced due to artificial stepping. 2. Improper cooperation of concrete or improper feeding will cause concrete to segregate, lack of slurry in the pouring site or serious leakage of formwork, resulting in leakage of slurry. 3. The cross-section of the engineering structure is small, the steel bars are too dense, the ambassador stones are stuck on the steel bars, concrete water ... Details >>
  • When pumping concrete pumps at lower temperatures, we must also pay attention to some problems to avoid unnecessary problems in engineering operations. Today, I will explain some things to pay attention to when concrete pumps are at low temperatures. The corresponding method, but it is more convenient to cast concrete with a concrete pump at a low temperature of -20 ° C than at a high temperature. As long as the flushing water in the water tank is always moving, this temperature will not freeze ... More >>
  • At that time, in response to the world ’s environmental requirements for energy conservation and emission reduction, all manufacturers in the construction machinery field were moving towards producing energy-saving and environmentally friendly concrete pumps. So what kind of concrete pump can produce energy saving and emission reduction after all? Specifically, energy-saving and emission-reducing concrete pumps usually have the following characteristics. I. Intelligent speed control technology Intelligent driving refers to the intelligent programming setting to ensure that the vehicle can intelligently control the engine rotation according to the operating environment ...

  • Concrete pumped concrete preparation is confirmed according to different strength specifications. Concrete strength specifications are confirmed according to statistical calculations of similar concrete. Together, the following requirements should be met: 1. When the concrete strength grade is C25, its strength specification is poor. The accounting value is less than 2.5MPa, and the standard deviation for calculating the preparation strength should be not less than 2.5MPa; when the concrete strength grade is C30, and the calculated value of the strength specification difference is less than 3.0MPa ...

  • Before assessing the possible causes of pipeline incidents, we must first determine the incident model. In short, there is a problem when any part of the pipeline system causes the "useful amount" of the product to leak occasionally. The term "useful amount" is to distinguish between "event" and harmful leakage. Unless the transport medium is highly toxic, Otherwise, the slight leakage of the equipment near the flange and the concrete pump pump pipe is irrelevant (for us ... Details >>
