Waterproof Drainage 100KN Geogrid For Road Construction

Road Extension Project Combining Old New Prevention Department Uneven Subsidence Caused Cracks Glass Fiber Geogrid

Glass Fiber Geogrid Introduction

Fiberglass geogrid is a kind of new geosynthetics for the reinforcement of road surface and rodbed.This product is made of fiberglass filament by woving machine imported abroad.After coated,it has featurers of alkali-resistance.This geogrid is mainly used in new road,soft road surface to enlarge the loading capacity and road maintainence to prevent the road crackle.

Glass Fiber Geogrid Specification

Glass Fiber Geogrid Features:

High tensile strength,elasticity modulus and low elongation;Heat resistence,no creep deformation,stable physical ad chemical properties;Crackle-resistence in high or low temature,or in road reflection;Excellent compatibility with asphalt and concrete of road surface,either soft or hard land;Compared with the trational road surface,it reduces the cost,prolong the service life,and avoid the reflection road crackle.

Glass Fiber Geogrid Application:

1. Old asphalt concrete pavement, reinforced asphalt surface, prevent and cure diseases.
2. When the cement concrete pavement is rebuilt into composite pavement, the reflection cracks are caused by the shrinkage of the slab.
3. Road renovation project, prevention and treatment of cracks caused by new old joint and uneven settlement.
4. The reinforcement treatment of soft soil foundation is conducive to the water separation and consolidation of soft soil, which can effectively restrain the settlement, even the stress distribution and enhance the overall strength of the subgrade.
5. Shrinkage cracks are produced in the semi-rigid base of the new road, and the reinforcement is used to prevent the pavement cracks caused by the reflection of the foundation cracks.

Classification and construction method of glass fiber geogrid

There are two kinds of glass fiber geogrids with and without self-adhesive. Those with self-adhesive can be directly laid on the leveled base, while those without self-adhesive usually adopt nail fixation method.

1. Construction site: it is required to be compacted, level and clean, except for sharp protuberances.

2. Grid laying: on the flat and compacted site, the main stress direction (longitudinal) of the grid installed and laid shall be vertical to the axis of the embankment, and the laying shall be flat without wrinkles, and shall be tensioned as far as possible. The main stress direction of the laid grid is Zui good, and there is no joint in the whole length. The connection between width and width can be bound and overlapped manually, and the lap width is not less than 10cm. If the grating is set in more than two layers, the seam between layers should be staggered. After large area laying, the flatness shall be adjusted as a whole. After a layer of soil is filled and before rolling, the grid shall be tensioned again with manual or machine tools, and the force shall be uniform, so that the grid is in a straight stress state in the soil.

3. Selection of filler: the filler shall be selected according to the design requirements. Practice has proved that except frozen soil, swamp soil, domestic waste, chalk soil and diatomite, they can be used as fillers. However, gravel soil and sand soil have stable mechanical properties and little influence by water content, so they should be preferred. The particle size of the filler shall not be greater than 15cm, and the gradation of the filler shall be controlled to ensure the compaction weight.

4. Paving and compaction of filling materials: when the grid is laid and positioned, it shall be filled and covered in time, and the exposure time shall not exceed 48 hours. In addition, the flow process method of laying and backfilling can also be adopted. Push the filler to the middle and then fix it. The rolling sequence is from both sides to the middle. During rolling, the roller can not directly contact with the reinforcement material, and the vehicle is not allowed to drive on it for fear of dislocation of reinforcement material. The layered compaction is 20-30cm. The compaction degree must meet the design requirements, which is also the key to the success or failure of reinforced soil engineering.

5. Waterproof and drainage measures: in reinforced soil engineering, the drainage treatment inside and outside the wall must be done well; the foot protection should be done to prevent erosion; the filtering and drainage measures should be set in the soil, and the geotextile should be set if necessary
