With the continuous upgrading of high-end projects such as bridge reinforcement, marine protection, long-term tunnel support, coastal infrastructure, and military protection, the shotcrete construction scheme of UHPC (ultra-high performance concrete) mixed with steel fibers has become the mainstream choice in the fields of long-term support and structural repair due to its outstanding advantages such as ultra-high strength, excellent toughness, impermeability and corrosion resistance

Are you facing challenges such as difficult concrete pouring on construction sites, slow material delivery to high-rise buildings, inaccessibility in confined spaces, frequent pipe blockages causing work delays, and high labor costs? Qingdao Saintyol DAWIN Machinery with over 20 years of experience in pumping equipment, has refined its full range of concrete delivery pumps with cutting-edge technology, covering all scenarios including residential construction, high-rise buildings, tunnels,

In wet-mix shotcrete operations for tunnels, mines, and slope stabilization, traditional equipment has long struggled with four major pain points: persistently high rebound rates, frequent pipeline blockages, unstable material flow (pulsation), and insufficient pumping power. These issues not only lead to significant raw material waste and costly downtime but also create quality risks such as poor layer density, hollow spots, delamination, and substandard structural strength.

Fine Aggregate Concrete/Mortar concrete pump | The "Main Force" for Underfloor Heating Backfill and Secondary Structures. Fine aggregate concrete and mortar are widely used in underfloor heating backfill, roof slope finding, secondary structure pouring, and sleeve grouting. These materials have fine aggregates and require high fluidity, making them prone to pipe blockage during conveying.

Qingdao Saintyol DAWIN Machinery shotcrete truck robot Its foldable multi-joint boom breaks through spatial limitations, enabling 360° spraying without blind spots. Whether it's high-altitude work on tunnel arches or precise spraying of sidewalls, no additional scaffolding is needed, significantly reducing preparation time and making construction more efficient and convenient

Saintyol DAWIN Machinery concrete pumps break construction boundaries with powerful performance, easily overcoming the challenges of high-lift, long-distance delivery. With a maximum pumping pressure of 32MPa, a maximum vertical pumping height of 250 meters, and a horizontal delivery distance of up to 1000 meters, whether it's pumping a 48-story super high-rise residential building to the top or delivering concrete horizontally over a 3-kilometer tunnel, it can deliver concrete stably

QZHP-3016B and QKSP-20A auto mobile shotcrete truck, have a concrete discharge capacity of up to 30 cubic meters per hour and a conveying capacity of up to 22 cubic meters per hour, respectively. Based on standard spraying thickness, a single unit can complete nearly 300 square meters of work surface per hour, increasing work efficiency by more than 30% compared to traditional equipment and several times that of manual spraying.

On the front lines of railway tunnel, highway slope, and water conservancy culvert construction, concrete spraying and shotcrete is always of paramount importance—ensuring project quality, meeting deadlines, ensuring safety, and balancing environmental protection and cost.

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.

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
