Geogrid manufacturer ＂ 13285449688 ＂ wechat ＂ 13184113881 ＂ geogrid detection and cleaning of lower bearing layer → manual laying of geogrid → lapping, binding and fixing → paving of upper subgrade soil → rolling → detection
.
The geogrid is laid on the flat lower bearing layer according to the width required by the design, and the upper and lower filling materials are free of impurities that damage the geogrid
.
When laying on the geogrid, the strength of the geogrid will be improved The height direction is perpendicular to the embankment axis, and the geogrid is laid horizontally
.
When laying, the geogrid is taut and straightened to avoid wrinkles, distortions or potholes
.
The longitudinal splicing method of geogrid is adopted, and the overlapping width is not less than 20cm
.
It is suggested that after the geogrid is paved, the upper layer filler should be laid manually, and the rolling should be completed in time to avoid long-term exposure to the sun
.
Then, the material should be transported, leveled and rolled mechanically
.
The mechanical paving and rolling should be pushed from both sides to the middle, and the rolling should be carried out from both sides to the middle, and the compactness should meet the standard requirements
.
All construction vehicles and construction machinery shall not be driven or parked on the paved geogrid
.
The quality of geogrid shall be checked at any time during construction
.
If any damage is found, such as breakage, puncturing and tearing, it shall be repaired or replaced according to the degree
.
Traditional slope protection materials can be divided into two categories: one is granular slope protection, represented by dry masonry, which has strong adaptability to bank slope deformation, easy to obtain materials, simple construction and convenient maintenance, but the construction quality is difficult to control; the other is integral slope protection, represented by bag concrete, which has good integrity and strong resistance to wind and waves Subgrade geogrid in high-grade highway with geogrid construction technology and process and glass fiber geogrid in municipal reconstruction, glass fiber geogrid in harsh environment makes geogrid special material, mainly used for highway, railway and other subgrade treatment, in recent years gradually introduced into water conservancy project
.
The stone mat slope protection made of geogrid has both integrity and flexibility, strong adaptability to slope deformation, high flexibility, not easy to break, and can withstand large range of deformation without collapse
.
The surface of the stone mat after cage loading is rough, which is conducive to sediment deposition and plant growth, and has good environmental protection effect
.
It has strong ability to resist chemical erosion of river engineering environment
.
When the carbon black content is 2%, the stone mat slope protection has good environmental protection effect, It has good destructive ability and high tensile strength
.
It can resist the scour of strong current under water; it has strong ability to resist the impact of natural damage and bad weather; it can prevent the damage caused by hydrostatic force; it is convenient for construction without special technology; it can save transportation cost
.
It can be transported in rolls and cut on the construction site
.
Geogrid manufacturer “13285449688” wechat “13184113881” glass fiber geogrid plays an important role in municipal reconstruction
.
Glass fiber geogrid is a widely used reinforcement material in municipal reconstruction, first-class highway and expressway reconstruction, which can effectively reduce pavement settlement and cracks
.
The main components of glass fiber are: silica, which is an inorganic material with stable physical and chemical properties, high strength, high modulus, high wear resistance, excellent cold resistance and no long-term creep; good thermal stability; network structure can lock and limit polymerization; improve the bearing capacity of asphalt mixture
.
Because the surface is coated with special modified asphalt, it has double composite properties, which greatly improves the wear resistance and shear resistance of geogrid
.
Geogrid manufacturer “13285449688” wechat “13184113881” steel plastic geogrid will appear reflection crack reason “steel plastic geogrid asphalt overlay on the old cement concrete pavement, its main function is to improve the use function of the pavement, but it has little contribution to the bearing effect, the rigid concrete pavement under the overlay still plays a key bearing role
.
The asphalt overlay on the old asphalt concrete pavement is different, and the asphalt overlay will bear the load together with the old asphalt concrete pavement
.
Therefore, the asphalt overlay on the asphalt concrete pavement, in addition to reflection cracks, but also because of the long-term effect of the load fatigue cracking
.
We do the stress analysis of the asphalt overlay on the old asphalt concrete pavement: because the asphalt overlay is a flexible surface with the same property as the asphalt overlay, when it is loaded, the road surface will be deflected
.
The asphalt overlay which is in direct contact with the wheel is under pressure, and the asphalt overlay is under tension in the area outside the wheel load edge
.
Because the force properties of the two stress areas are different and close to each other, Po damage is easy to occur at the junction of the two stress areas, that is, the sudden change of the force
.
Under the action of long-term load, fatigue cracking occurs
