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

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.

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.

High temperatures in summer can reduce the concrete placing boom viscosity of hydraulic oil, leading to unstable system pressure and even leakage. Before construction, check the oil level and quality of the hydraulic oil to ensure that the oil level is within the normal scale range. If the hydraulic oil is found to be darker, turbid or has impurities, replace it with anti-wear hydraulic oil that meets the summer use standards in time.

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,

Pre-installation Inspection, First, before installing the concrete placing boom, carefully inspect each component and pipe clamp of the assembled boom.

In the construction of high-rise buildings, any interruption in concrete pouring not only affects the overall structural integrity but may also disrupt the rhythm of subsequent processes such as rebar installation, formwork, and curing. Ensuring uninterrupted concrete placement becomes a crucial issue in project management. Konel Heavy Industry's hydraulic placing boom addresses this need by providing a continuous, autonomous, and low-dependency solution.

In the construction engineering field, concrete pumping has always been a core element determining construction schedule and quality. High-rise building pouring faces challenges such as insufficient or unstable concrete delivery, unsuitable equipment leading to inefficiencies in special working conditions, and large-scale projects with low tolerance for error and stringent requirements

Saintyol DAWIN Machinery wet concrete shotcrete robot cover large, medium, and small cross-section working conditions, featuring dual power, large displacement, wide coverage, and low rebound, adapting to different engineering needs. the QZHP-3016B large wet spraying trolley is the preferred model for large cross-sections, with a theoretical spraying volume of up to 30m³/h, It has a vertical spraying height of 16m and a horizontal spraying width of 27m, and its wide coverage reduces blind spots

Saintyol DAWIN wet concrete spraying trolleys are equipped with high-efficiency spraying systems, with different models each having their own focus: the QZHP-3016B has a concrete discharge capacity of up to 30 cubic meters per hour, while the QKSP-20A has a conveying capacity of 22 cubic meters per hour. Based on standard spraying thickness, a single unit can complete nearly 300 square meters of work surface per hour

The QKSP-20A medium-sized robotic shotcrete machine wet concrete spraying trolley is more suitable for small to medium-sized work conditions, balancing efficiency and flexibility. Its theoretical spraying capacity can reach 22m³/h, meeting the spraying needs of small to medium cross-section projects. A single unit can complete nearly 300㎡ of work surface construction per hour, several times more efficient than traditional manual spraying.
