Information

Coil Grout manufacturers tell you that there are two main types of grouting construction methods, one is according to the setting method of grouting pipe, and the other is according to the mixing method of grouting material or the method of pouring.

Classification by grouting pipe setting method:
1. Drilling method. Coil Grout manufacturers tell you that this method is mainly used for bedrock or gravel layers or foundations that have been compacted. Compared with other methods, this method has the advantages of not disturbing the foundation soil and using a packer. But the general project cost is higher.
2. Enter the method. When the grouting depth is shallow, the driving method can be used, that is, a plunger is installed at the top of the grouting pipe, and the grouting pipe or the effective grouting pipe is driven into the formation with a pile hammer or a vibrating machine. The Coil Grout manufacturer tells you that in order to remove the plunger, the grouting tube after being driven is pulled up, so it cannot be poured from the top down. When an effective grouting pipe is used, many holes are blocked during the driving process, and cleaning is time-consuming.
3. Injection method. This is the method used in relatively homogeneous sand layers or grouting pipes in difficult places. This method uses water jets from mud pumps and nozzles to set up grouting pipes. Because it is easy to disturb the foundation, it is not an ideal method.
Classification by perfusion method:
1. One solution one system approach. The Coil Grout manufacturer tells you to put all the materials in the same box, pre-mix, and then grouting, which is good for longer gel times.
2. Two solutions in one system. The A solution and the B solution were pre-packed in different boxes prepared separately, transported by a pump, and the two solutions were combined at the head of the grouting pipe. This method of mixing in the grouting tube for infusion is suitable for short gelling times. The Coil Grout manufacturer tells you that the two solutions can be mixed in equal amounts or in proportion.
3. Two solutions and two systems. Put the A solution and the B solution in different boxes and transport them with different pumps. At the moment when the top of the grouting pipe (parallel pipe, double-layer pipe) flows out, the two solutions will converge and be grouted. The Coil Grout manufacturer tells you that this method is suitable when the gel time is instantaneous.
Classification by grouting method:
1. Drill pipe grouting method. Drill pipe grouting construction method is a method in which the drill pipe (single pipe) used for grouting is injected into the formation through the drill pipe after drilling the hole to the specified depth. The starting point of grouting after the borehole reaches the specified depth. Coil Grout manufacturers tell you that compared with other grouting methods, the advantages of the drill pipe grouting method are easy operation and lower construction costs. The disadvantage is that the slurry is easily sprayed to the surface along the gap between the drill pipe and the borehole, and the spraying direction of the slurry is limited, that is, it is a single vertical direction.
