Geogrid is a good soil reinforcement material
In the channel improvement project, there are supporting anchorages in the service area, which can provide ships with services such as berthing, garbage collection, power supply, refueling, and water filling. Retaining walls need to be built at fixed points in some service areas and backfilled with materials behind the walls. When the backfill soil has poor viscosity, the retaining wall will bear greater active earth pressure, especially when the water level is the same as the height of the retaining wall, the retaining wall will bear the greatest pressure.
In order to reduce the pressure on the retaining wall and ensure the safety of the anchoring construction in the service area, measures should be taken to control the pressure on the retaining wall. Generally speaking, there are two ways to reduce the water level or strengthen the retaining wall. Lowering the water level is to reduce the external force on the retaining wall, and strengthening the soil is to increase the strength of the soil itself. Geogrid is a good soil reinforcement material with good tensile properties so that it can achieve a good reinforcement effect when applied to the soil reinforcement of the retaining wall in the anchorage area of the service area, and the total pressure on the retaining wall is significant Lowering so that the retaining wall can fully play its due role.
The geogrid used in the reinforced retaining wall can be a polypropylene double-stretched plastic grid, and its longitudinal and transverse tensile strength should meet the design requirements. The spacing, quantity, and length of the geogrid should meet the design requirements, the tie strips should be straightened, and the tie strips should be firmly connected to the plate and tie strips to prevent damage to the geogrid during the backfill and compaction process.
