The grout is a special filling material between the bottom plate of the equipment and the concrete bottom, transmitting the load and its oscillation. The quality of the grout, and ultimately the usefulness and durability of the transfer load and its oscillation. The grout is a special filling material between the equipment floor and the concrete base, transmitting the load and its oscillation. The quality of the grout is ultimately the usefulness and durability of the transmitted load and its oscillations. When installing the equipment, we temporarily fix the equipment on the concrete base, first fix it with bolts, then grout the equipment floor, and permanently fix the equipment on the concrete base to transfer the equipment load and the vibration during operation to the concrete. foundation. If the grout body does not have a useful transfer load and its oscillation, the equipment will be damaged during operation.
The main purpose of water conservancy construction is to block rivers, build dams, repair reservoirs, build power stations, and build dams to ensure that safety must be located on a stable foundation to “stable bottomâ€. There are two common methods for root treatment, one is excavation and the other is filling. The open pillow is to remove the faulty fracture zone, the fault development and the high permeability geological structure in the weathered layer of the surface and the shallow layer of the bedrock, but the complex geological defects in the deeper layer need to be treated by drilling grouting. . Diversion tunnels, underground powerhouses and warehouses, in order to ensure the safety of the caverns, it is necessary to adopt grouting grouting method to backfill the gaps and stabilize the surrounding rock. The dam sections of the block casting are integrated into one, in order to improve the transmission stress conditions of the concrete dam, and the joint grouting of the dam body is also required.
With the continuous development of non-shrinking high-strength grouting technology, the grouting effect is getting better and better. In the water conservancy and hydropower project, more and more projects and more and more missions are adopted to adopt grouting technology to deal with more complicated geological conditions and building defects. Therefore, we are required to engage in the dry warfare of the grouting construction, and the employees should study this professional and practical technical science, constantly sum up experience, improve the construction process, renovate the construction equipment, meet the new challenges, and undertake more arduous tasks. mission.
