Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a device for lifting a road depression in a building workshop. Background Art

[0002] Bricks are often used for paving factory roads. Bricks have good durability and compression resistance, and can withstand the heavy pressure of pedestrians and vehicles while preventing cracks in the road surface. The laying of bricks is also flexible, and they can be spliced ​​and replaced as needed, which is convenient for maintenance and repair. The use of cement requires more manpower and time, and cracks or damage require the entire piece to be replaced. However, there is also a problem with the use of bricks. With the impact of rain, the soil on the ground will be washed away. Over time, the ground will become concave and affect the flatness of the ground. The existing repair method is to remove each brick separately and then directly lay the soil. However, the above repair method will cause the soil at the joints of adjacent bricks to fall off during the process of removing each brick separately, thereby causing the problem of unstable brick joints. Summary of the invention
