Mine concrete pump

Mine concrete pump for underground work as a pump, more and more welcome to the construction side.how reinforced mine concrete concrete pump?
Experts pointed out: with mine reinforced concrete pump concrete process is very simple, and very adaptable, usually requires a mature design juice and construction experience, but mine concrete pump more suitable for smaller span T-beam bridge or Itabashi reinforcement. Mine usually using reinforced concrete pump will be significantly improved after the bridge stiffness, load capacity can achieve better results.
 
Mine usually reinforced concrete pumps will be taken to increase the cross section of reinforced concrete method, which are generally two ways, one is thicker deck, the other is to increase the main girder rib height and width. On these two methods are based on the original structure and then pouring a certain thickness of reinforced concrete in order to reinforce this transformation technique more commonly used in reinforced concrete bridge on.

Mine gate valve concrete pumps after a period of use, it is often on, there will be deep dent on the lower seat, then you can be patched with a rod, and then you can continue to use by grinding wheel, general gate after prolonged use becomes sharp, thin, if you want to continue to use, can be corrected by hand wheel on the gate to coincide with the valve seat, and add copper sheet between the separator and the shell to adjust the gap between each other, in order to extend the period. In addition, as a gate valve cylinder piston hydraulic cylinder, prolonged use can cause the oil temperature is too high, causing damage to the seal on the piston, causing the seat weakness, and therefore must be replaced at this time the seal on the piston.
