Description

Technical Field

[0001] The utility model relates to the technical field of fixed brackets, in particular to a cement-stabilized gravel bracket. Background Art

[0002] Cement stabilized gravel uses graded gravel as aggregate, adopts a certain amount of cement binder and sufficient mortar volume to fill the gaps in the aggregate, and is spread and compacted according to the interlocking principle. The strength mainly depends on the interlocking and locking principle between the gravel. At the same time, there is sufficient mortar volume to fill the gaps in the aggregate and the cement bonding effect. It has high initial strength, and the strength increases with age and quickly forms a slab, so it has higher strength. Cement stabilized gravel is an ideal base material for high-grade pavement, and it is flat and solid after forming.

[0003] When using existing cement-stabilized gravel supports, the supports are usually set on the roadside to form a barrier, and then cement-stabilized gravel is laid on one side of the support. However, since the thickness of cement-stabilized gravel laid on different road surfaces is different, the height of the support needs to be adjusted. However, the existing support height adjustment method is relatively cumbersome, and manual operation is time-consuming and labor-intensive, which easily affects work efficiency and is difficult to meet actual usage needs.
