[0002] The use of foundation backfill technology is indispensable in construction projects. There are many aspects of construction technology application involved in the foundation alone. The application of backfill construction technology can ensure the quality of each construction link. The foundation refers to the deformation of the base under the load of the building. The stratum must not be ignored. The foundation refers to the structure that transmits the load of the building to the bottom of the base. As the load supporting the building, the foundation must have the stability and damage prevention strength. The foundation of the construction project is the same as the foundation of the house construction. Both require the use of foundation backfill technology. The soil quality in each region is different, which means that the foundation construction design plan for each construction project is also different. There are many uncontrollable factors in different geology, which requires relevant experts and professional construction personnel to pay more attention to it and not be careless, otherwise it will bury a huge hidden danger for the construction of subsequent projects.

[0003] During the backfill construction of the existing fertilizer trough, due to the complex terrain, the concrete feeder truck cannot directly reach the vicinity of the fertilizer trough. The staff is required to set up a chute near the fertilizer trough and use the chute to cast the fertilizer trough. The existing castables are added with curing agents. During the transportation process, the materials will be exposed to the air for a long time, causing a thick layer of cement to adhere to the inner wall of the chute, which is not only difficult to clean, but also reduces the overall feeding efficiency, thereby extending the construction period.
