Description

Technical Field

[0001] The invention relates to the technical field of laying devices, in particular to a bentonite sand barrier laying device. Background Art

[0002] Bentonite is also called bentonite, soap clay or bentonite rock. Bentonite has strong hygroscopicity and swelling properties. It can absorb 8 to 15 times its own volume of water, and its volume can expand several times to 30 times. It can be dispersed into gel and suspension in water medium. This medium solution has certain viscosity, thixotropy and lubricity. Due to its strong water absorption and swelling properties, bentonite is often used as the main component of sand barrier structure, which can play a role in preventing soil and sand, and retaining water and soil moisture.

[0003] When considering bentonite as a component of the sand barrier structure, it needs to be laid like a traditional sand barrier structure, and the corresponding laying equipment is needed to assist in the laying, so that the bentonite can be evenly laid on the top of the sand to play its role.

[0004] Generally, when laying sand barriers, traditional sand barrier laying devices often lay bentonite and other component structures on the top of the sand, so that the bentonite covers the sand on the top. Due to the water absorption and expansion of bentonite, it acts on the sand on the top of the sand, while the sand at deeper depths will still lose water, making the bentonite layer on the surface unstable and reducing the actual effect of the bentonite. Shoveling out the sand alone and then mixing it with bentonite and laying it again with other equipment will increase the cost, and the synthesized bentonite layer can only be laid on the top layer of the sand. In this process, there will be a new sand layer covering, and the project volume is large and the cost is high.
