Geocell is widely used in geotechnical engineering. By laying geocell, the stability of slope can be strengthened effectively, and the dangerous situation such as landslide and collapse caused by topographic height difference can be prevented.
1. Preparation before construction
Determine the scope and location of construction
It is necessary to determine the scope and location of slope geocell laying according to the actual project site. Usually, we will determine the laying scope and positioning according to factors such as terrain height difference and slope size.
Conduct site survey and site survey
Such as assessment of topography, geomorphology, soil layer and lithology. According to the survey results, the site plan and elevation were drawn to prepare for the subsequent construction and laying. Select suitable specifications and prepare for construction.
2. Construction process
Basic treatment
The foundation treatment of the slope includes cleaning up the weeds on the slope, loosening the soil, and improving the slope of the soil. At the same time, the foundation should be strengthened to ensure that it can withstand the weight and pressure of the geocell.
Step treatment
In the construction process, it is necessary to carry out step treatment according to the slope slope, first cut the original steep slope into steps, and lay in accordance with the prescribed scope.
The laying of the geocell
After the foundation treatment and step treatment are completed, the geocell laying work begins. The specific operation is: first cut the geocell at the laying position, and then place it in the corresponding position, and strengthen and fix the connecting pieces between them.
Wall treatment
After the slope geocell is laid, it is necessary to reinforce and fix the laid wall layer by layer to ensure that the geogrid can be more solid and stable with the further advancement of construction.
Perform geocell surface treatment
After the entire geocell is laid, its surface needs to be treated, including surface reinforcement, vegetation coverage and other operations to ensure that it is better adapted to the natural environment.
3, regular maintenance and inspection
After the construction is completed, regular maintenance, cleaning and inspection work are required. This helps to find and solve the problem in time, so that the slope geocell can achieve a better use effect.
