Pre-embedded grouting pipe, disposable grouting pipe, repeatable grouting pipe, grouting pipe, also called spring skeleton grouting pipe, pre-embedded grouting pipe, maintainable grouting pipe, disposable grouting pipe and multiple-use grouting pipe
The embedded grouting pipe has the following characteristics and can be injected with a variety of materials such as cement slurry, polymer slurry, polyurethane chemical slurry and other materials.
Re-Injection After vacuum cleaning, the system can still be used for other purposes and can be re-injected at any time. Detectability The water absorption of the grouting pipe before and after injection can be measured with a simple and reliable method, which is rigorous. Safe and reliable. After more than ten years of application and laying experience in professional fields and successful grouting experience in large and medium-sized domestic projects, we ensure that we provide customers with the most professional technology and the best performance products.
Performance Principle During the concrete pouring process, when subjected to external concrete pressure, the rubber cover strip wrapped around the outside of the grouting pipe is tightly attached to the injection outlet hole of the central axis tube due to the pressure, thereby closing the entire system. , to prevent concrete slurry from mixing into the grouting pipe during the pouring process.
During the grouting process, when the pressure inside the grouting pipe reaches a certain level, the grout can push up the rubber cover strip under the pressure and overflow from the injection discharge hole, thereby filling the concrete cavity. Achieve the function of water-stop sealing.
Through the principle of vacuum cleaning, the pipes can be cleaned with water so that they can be reused. Pre-embedded grouting pipes are used for permanent sealing of construction joints, cold joints, seepage joints, gaps between floors and walls in concrete. It is very suitable to install grout pipes between the joints of new and old concrete. When water seeps into a joint, it can be sealed by injecting slurry through ports set in the surface. This method seals the joint. The appropriate grouting time can be chosen to grout after the concrete curing is completed. Leaking seams can also be permanently sealed using this method.
Injecting grout into the pre-buried grouting pipe can seal the joints between construction joint cold joint pipe leakage and the ground wall. Pre-embedded grouting pipes are divided into disposable grouting pipes and multiple-time grouting pipes. The disposable grouting pipe can be used for grouting once and cannot be reused. The multi-use grouting pipe can be used for grouting multiple times. The grouting is not limited by time. If water leakage occurs, slurry can be injected into the pipe body to fill and seal it.
Advantages: Simple installation, provided in complete sets. At the construction site, the grouting pipe is cut according to the actual required length of the joint. It is recommended that the longest grouting outlet length should not exceed 1 meter. Special installation equipment is required. The grouting time can be selected arbitrarily under pressure. When grouting is carried out downwards and inward, the grouting pipe liquid can be kept uniformly filling the entire pipe. The system allows grouting at relatively low pressure and does not affect the characteristics of the building grouting pipe itself. The installation or grouting process does not Ensures permanent sealing after damaging concrete slurry
