Steel pipe is primarily used for the pre-support of soft and fractured zones with short self-stabilization time, shallow buried sections, bias pressure sections at the mouth of tunnels, sand layers, gravel layers, and fractured fault sections. By using grouting technology, cement mortar is infiltrated into the geotechnical strata of the rock, which can improve the physical and mechanical properties of the geotechnical strata and enhance the anti-slip capability of the rock layers. After grouting, the steel pipe remains in the rock layer, providing certain anchoring and anti-slip functions, thus increasing the reliability and stability coefficient of the rock layers.

During the concrete pouring process, when external concrete pressure is applied, the rubber sealing strips wrapped around the exterior of the grouting pipe tightly adhere to the inlet and outlet holes of the central tube due to the pressure, thereby closing the entire system and preventing concrete slurry from mixing into the grouting pipe during the pouring process.

The steel flower pipe grouting process involves inserting the grouting pipe through drilled holes into the ground, using a segmented grouting technique to ensure more even distribution of grout under pressure, thereby achieving segmented control. To ensure even distribution, an external grouting pipe is set up during the grouting process and left in the soil. The external grouting pipe features grouting outlets at regular intervals, increasing the number of outlets. A shut-off valve is installed. During grouting, the internal grouting pipe equipped with a leak prevention device is placed inside the external grouting pipe, and grout is applied to the areas requiring it.

This results in a bored pile in the soil, with a tree-like network of pulp aggregates forming around the cracks of the pile, exerting strong shear forces. Grouting technology is a method that utilizes pressure to consolidate solidified slurry into the holes or cracks of rock formations and soil, or within buildings, to improve their physical and mechanical properties.

During the grouting process, when the pressure within the grouting tube reaches a certain level, the rubber gasket can be pushed upwards under pressure and overflow from the water injection exhaust outlet, thereby filling the concrete cavity and achieving waterproof sealing.

Based on the principle of vacuum cleaning, pipes can be washed with water for reuse. Steel flower pipes are used for concrete construction joints in new and old concrete, cold joints, pipe渗漏, wall gaps, and other long-term sealing applications, and are suitable for installing grouting pipes between gaps.

When water seeps into the joint, you can inject cement grout through the surface PVC port to seal the joint. After the concrete sets, you can choose an appropriate grouting time for grouting, or extend the leaking joint in this manner.
