The mechanical properties of concrete pumps, such as sand and gravel particle size, cement grade and mix ratio, are generally explained in the factory manual. Qingke Heavy Industry reminds you to follow the factory manual to meet the mechanical properties of concrete pumps during operation. The safety requirements for using concrete pumps are as follows:

Concrete placing boom Hydraulic system "physical examination" 1. Oil circuit hidden dangers: Check whether there are leaks, loose joints or surface damage in the hydraulic pipeline before starting, especially pay attention to bends and welding points. If the oil is turbid or contains bubbles,

In the vast world of tunnel construction, the Shotcrete wet concrete spraying machine of Saintyol DAWIN is like a bright star, shining with unique light, and can be regarded as a capable assistant to the construction team. Saintyol DAWIN, as an enterprise that has been working hard in the field of tunnel and subway construction for many years and has accumulated rich experience, has carefully created this wet spraying trolley with excellent performance with its profound technical background

In high-rise building construction, concrete placing has always faced the challenges of high labor costs and low operating efficiency. With automatic climbing technology as its core, the Saintyol DAWIN hydraulic concrete placing boom provides engineering teams with efficient and economical solutions by reducing manual intervention and simplifying the construction process.

On construction sites, high-altitude concrete pouring has always been a "difficult" problem: low efficiency, high risk, and even the slightest carelessness may cause safety accidents. But now, the emergence of the Saintyol DAWIN hydraulic concrete placing boom has solved all these problems! As a "high-altitude construction tool", it has redefined the efficiency and safety standards of concrete placing and pouring.

Current status of domestic construction Domestic projects are characterized by many mountains, many mines, and many water conservancy constructions, which means that my country needs to use a large number of wet concrfete spraying equipment shotcrete machine in national construction.

The role of cement in the pumping process The pumping pressure of concrete is transmitted by the liquid phase in it. The liquid phase carries the solid phase to move together to complete the pumping. Cement has two functions. One is the cementing effect, which makes the concrete maintain the state of solid phase surrounded by liquid phase during pumping
