Construction process of geotextile

1. The old pavement should be cleaned of dust, loose particles and sundries, and the surface should be kept dry. The sharp and abrupt parts of the road surface shall be leveled; for the seriously damaged and broken parts of the road surface, the broken parts shall be removed and repaired with asphalt concrete. For the pavement with serious cracks or ruts, a layer of 1-2cm leveling layer should be filled.

Precautions for construction of geogrid

The paving surface of the geogrid should be relatively flat. After the paving layer has passed the acceptance, in order to prevent the longitudinal skew phenomenon, first draw a white line or hanging line on the paving layer according to the width, and then start the paving, and then use iron Fix the end of the grille with nails (8 nails per meter width, fixed at an even distance), after fixing the end of the grille, use a paving machine to slowly pull the grille forward, and carry out manual labor for every 10 meters long. Tighten and straighten once until one roll of grille is finished, and then lay the next roll. The operation is the same as before. After laying one roll, use a 6T-10T road roller to roll it from the starting point to the forward direction.

The role of geogrid engineering

It has high strength, low creep, and can adapt to various environmental soils, which can fully meet the use of tall retaining walls in high-grade highways. It can effectively improve the interlocking and occlusal effect of the reinforced bearing surface, greatly enhance the bearing capacity of the foundation, effectively restrain the lateral displacement of the soil, and enhance the stability of the foundation.

Scope of application of plastic blind ditch

1) Reinforcement and drainage of road and railway subgrade shoulders; 2) Drainage of tunnels, subway underground passages, and underground freight yards; 3) Soil and water conservation for hillside and side slope development;

Product characteristics of flexible permeable pipes

1. The material of the soft permeable pipe 1) High carbon steel wire: phosphoric acid anti-rust treatment, PVC coating to prevent acid and alkali corrosion, unique steel wire spiral skeleton to ensure the smooth surface of the pipe wall and withstand pressure. 2) Non-woven filter layer: ensure effective filtration and prevent sediment from entering the tube. 3) Synthetic polyester fiber: The warp yarn is made of high-strength T-DOLON yarn or nylon yarn covered with PVC, and the weft yarn is made of special fiber, which has sufficient tensile strength.

Transport mode of HDPE double wall corrugated pipe

HDPE double wall corrugated pipe can be transported by various vehicles. During transportation, loading and unloading, it is not allowed to throw, hit, press, expose for a long time or get close to heat sources. Mixed transport with toxic and hazardous substances is not allowed. The perforated tube in the form of a disc cannot be transported flat.

Geogrid construction and laying method

Anchorage method: Fiberglass geogrid without self-adhesive enhances asphalt concrete pavement and prevents reflection cracks between pavement and pavement. Anchorage method can be used for construction, but it is advisable to lay fiberglass geogrid first, and then sprinkle hot asphalt for bonding.

Product use of geonet

It is used for roadbed reinforcement, making granular fillers and grids interlocked together to form a stable plane, preventing filler subsidence, and dispersing vertical loads; multi-layer reinforcement can be used in areas with harsh geographical conditions.
