[0002] Filling is an engineering operation used for land development and construction along lakes, seas and rivers. It is mainly used to transport materials such as sand, stone and soil through pipelines to the areas that need to be filled, so as to increase the land area and improve the terrain. Its working principle is to use a high-power pump to transport the material through the pipeline to the designated location, and then blow the material into the target area at the pipeline outlet.

[0003] However, the current process is to use traditional methods such as preloading and vacuum preloading to harden the site after the fill is blown, which has disadvantages such as long site treatment cycle and poor effect. Using soil stabilizer to mix and solidify the fill is an efficient soft foundation treatment method, but due to the poor bearing capacity of the fill foundation, it is difficult to bring the mixing equipment to the site, and the mixing uniformity is poor and the cost is high. Therefore, it is necessary to develop a device that can directly add curing agent materials during the filling operation to improve the curing efficiency and the mixing uniformity of the curing agent and the fill.
