Roadbed Construction: Expert Tips on Selecting and Implementing Hunan Geotextiles for Highways!
Release date:
2020-09-18
Subgrade embankment is primarily carried out to ensure the stability of the highway. an All about stability. While general highways place greater emphasis on subgrade treatment, municipal roads—due to their different purpose—primarily serve people and typically involve minimal embankment. As a result, subgrade construction is rarely required; instead, excavation is the dominant approach, with earthwork carried out to a certain extent. shen Handle within the specified range. Roads, however, are primarily designed for vehicles and thus take precedence over the surrounding environment. As a result, embankment construction is more common—this strengthens the roadbed and enhances its water stability. Additionally, since there are no sewer pipes, maintaining an appropriate elevation is crucial; too low would also be problematic. A dense roadbed ensures minimal settlement and excellent overall stability—otherwise, cracks could develop in the subgrade, rendering the entire road project essentially wasted.
So, how do you choose the right one? Hunan Yiyang Geogrid What about that?
First, we need to assess the construction environment—whether it’s a typical inland highway or a seaside pier. If it’s the former, we can opt for solutions that offer high cost performance. Yunnan Yuxi Steel-Plastic Geogrid , this type of roadbed geogrid can most Gao does it 100kn Above, and jia Gebi of equal strength Guangxi Nanning Bidirectional Plastic Geogrid To be nearly half the price, ensuring construction quality while spending less money. most The main thing is its ji High-strength materials can better enhance the performance of roadbeds, especially on roads that need to accommodate ultra-heavy vehicles—such as those used in coal mines and steel plants. Yunnan Yuxi Steel-Plastic Geogrid To reinforce the roadbed. For roadbeds along coastal docks, reinforced concrete is often used. Guangxi Nanning Bidirectional Plastic Geogrid Because this type of grating is made from polypropylene or polyethylene plastic, it’s completely water-resistant. In particular, it’s widely used in land-reclamation projects—cages constructed from this material are filled with stones and then dropped into the sea to build up new land. It’s exceptionally resistant to corrosion, making it an ideal choice for such applications.
Second, we need to select based on the size of the crushed stone used as construction filler. Yunnan Yuxi Steel-Plastic Geogrid The mesh size is typically 10-14 A square centimeter, Guangxi Nanning Bidirectional Plastic Geogrid (Two-way) for 4 1 cm square mesh, depending on the size of the crushed stone used for the subgrade— if the stones are larger, we recommend using Yunnan Yuxi Steel-Plastic Geogrid , if they're all diameters 3-4 For small gravel particles measuring less than one centimeter, it is recommended to use Guangxi Nanning Bidirectional Plastic Geogrid 。
The construction process flow for highway subgrade:
Construction Preparation ( Material handling, layout ) → Base Treatment ( Purity and tranquility ) → Hunan Yiyang Geogrid Laying out ( Laying method, overlap width ) → Filler ( Method, particle size ) → Roll-over grating → Lower-layer grating paving.
Highway Subgrade Hunan Yiyang Geogrid Construction method:
① Foundation Treatment
First, level and compact the subgrade, ensuring that the unevenness does not exceed 15 mm, the compaction meets the design requirements, and the surface must be free of any hard protrusions such as gravel or boulders.
② Hunan Yiyang Geogrid Laying out
a. Storage and laying out Hunan Yiyang Geogrid At this time, avoid exposure and prolonged contact to prevent performance degradation.
b. Laid perpendicular to the direction of the line, with overlaps complying with the requirements of the design drawings, securely fastened, and ensuring that the strength at the connection points in the direction of applied force is at least equal to the material's designed tensile strength—and that the lap length meets or exceeds the specified minimum. 20 Centimeters.
c. Hunan Yiyang Geogrid The quality meets the specifications outlined in the design drawings.
d. Construction must proceed continuously, ensuring no twisting, wrinkling, or overlapping occurs. Pay close attention to tightening the grating to evenly distribute the load—use manual tensioning to achieve a uniform, smooth surface that lies flat against the underlying support. Additionally, employ measures such as inserting stakes to securely fasten the material in place.
e. Hunan Yiyang Geogrid At this point, the long-hole direction aligns with the cross-sectional orientation of the line, so the geogrid in Yiyang, Hunan, must be straightened and flattened. The grid ends should be treated according to the design specifications.
f. Hunan Yiyang Geogrid Immediately backfill the material after paving, ensuring the interval does not exceed 48h , to prevent it from being directly exposed to sunlight.
③ Filler
After laying the grating, backfilling should be carried out promptly. Backfilling shall proceed according to " First the sides, then the middle " The filling should follow symmetrical principles, and it is strictly prohibited to first fill the middle section of the embankment. Fill material must not be unloaded directly onto the surface. Hunan Yiyang Geogrid Up, bi Must be unloaded onto the already paved soil surface, with a unloading height not exceeding 1m . All vehicles and construction machinery must not be allowed to drive directly on the paved surface. Hunan Yiyang Geogrid Walking is permitted only along the embankment.
④ Rolling grille
At di After the first layer of fill reaches the specified thickness and is compacted to the designed density, the geogrid is rolled back and wrapped around. 2m Secured to the upper layer of Hunan Yiyang geogrids and manually trimmed for anchoring, with soil piled along the outer side of the rolled-over edge. 1m , protect the grating to prevent man-made damage.
⑤ Complete one layer using the method described above. Hunan Yiyang Geogrid Lay the first layer of geogrids, and follow the same procedure for laying the remaining layers. Once all the geogrids have been installed, proceed immediately with the construction of the upper embankment.
Hunan Yiyang Geogrid Construction precautions:
① Grating should be used most High-intensity direction and recipient most The directions of high stress are consistent.
② Heavy vehicles should be avoided from driving directly onto the newly laid surface whenever possible. Hunan Yiyang Geogrid Driving uphill.
③ Minimize as much as possible Hunan Yiyang Geogrid The amount of cutting and sewing is carefully controlled to avoid waste.
④ When constructing during the cold season, Hunan Yiyang Geogrid It becomes hard and can easily cut your hands or scrape your knees—so be careful! an Sure.
