Description

Technical Field

[0001] The utility model relates to the technical field of foundation pit filling, and more specifically, to a foundation pit fluid mixture filling and conveying device. Background Art

[0002] The excavation pit fluidized mixture filling and conveying device is a specially designed device used to efficiently and safely convey fluidized mixtures (such as concrete, mortar, and soil amendments) into the excavation pit. This device is widely used in construction, infrastructure development, and environmental remediation, significantly improving construction efficiency and ensuring quality and safety.

[0003] In the prior art, when conveying the fluid mixture for filling the foundation pit, the conveying hose is mostly connected directly to the discharge end of the concrete mortar truck, and the other end is set at one point in the foundation pit, so that the fluid mixture flows into the foundation pit. However, with this method, the filler entering the foundation pit is mainly accumulated in one place and gradually diffuses outward under the diffusion property of the fluid to realize the filling of the foundation pit. During this process, manual assistance is required to pull the filler outward so that the filler is evenly distributed in the foundation pit.

[0004] The uniformity of the fluid mixture during backfilling is poor, making it difficult to flexibly adjust the position of the filler when it is discharged according to the shape of the foundation pit, and the convenience of manual assisted operation is poor;

[0005] In addition, after the fluid mixture enters the foundation pit, there will be some air inside it. If this air is not expelled in time, it will affect the density of the fluid mixture after filling in the foundation pit and affect the strength after drying. Utility Model Content
