Ống địa kỹ thuật Geotube – Thi công ống địa trong công trình biển

Geotube Geotube is a technology for shore protection and reclamation. It is a highly effective soft dike solution. Widely used in current coastal construction projects.

Soft geotube breakwaters have the trade name Geotube or Max – Tube. When constructing this pipe, people pump a solution of sand and water into the pipe to fill it with sand and the pipe swells out into an oval shape lying on the ground. Water will escape through the geotextile fabric and gradually leave a soft sand dike in the geotextile pipe shell mentioned above.

GEOTUBE geotextile tube

In this way, when completed, this pipe will form a soft dike with the purpose of preventing riverbank or coastal erosion, reducing wave pressure, creating beaches... depending on how the pipe is laid.

Geotube soft dikes were first applied by the US Army Engineering Association (USACE) in 1962 and have become a widely used technology in over 50 countries for construction and maintenance. Protect coastal and riverbank structures quickly and for a long time, at a reasonable cost. Especially used as soft dikes for marine structures.

What is Geotube?

Geotubes are manufactured from high-strength Polypropylene (PP) woven fabric, sewn at the factory into tubes with sizes required for each project, then pumped with sand, or other materials at the site. into the pipe to form soft dikes with a height of 3-4m after pumping.

High applicability

The geotextile material used to make these soft dikes is specially manufactured to ensure high durability to withstand the pressure of sand pumping, the pressure of waves, tides, and impacts while ensuring The drainage speed is high but the fabric hole size must be small to ensure that the material in the hose does not escape.

Coastal breakwater works

Using Geotube helps prevent erosion and erosion of river and sea banks, sediment deposition, and coastal regeneration, friendly to the surrounding environment. In addition, Geotube geotubes are also used as temporary paths for the construction of breakwaters and sea reclamation projects.

The capacity of the geotube is large

Geotube geotubes are constructed of high strength woven geotextiles and are a cost effective choice for drainage, dredging and bank protection applications. High strength geotextiles allow Geotubes to be made large enough to hold more than 900m3 of material inside.

Geotube with large capacity

Common sizes of geotubes range in diameter from 2.3 m to 27.4 m and length from 30 m to 60 m. Other sizes are also available upon request.

Where are geotubes used?

For drainage applications, Geotubes are filled with slurry with a high water content to facilitate pumping. Excess water is then filtered through the soil pipe walls and solid particles are trapped in the pipe. This will reduce the volume of high-cost liquid materials that need to be removed.

Coastal works, wave breakers

Geotubes used in hydraulic applications can prevent shoreline erosion and in some cases can also restore lost shorelines.

Geotubes can also be used to reconstruct entire islands that are being lost due to wave action from increased boat traffic.

In shoreline applications, Geotubes are commonly installed with an erosion barrier that connects the large tube to a small anchor tube. Once filled, the Geotubes can then be covered with sand or rocks over the mantle.

Photos of geotube construction

For underwater or offshore applications, Geotubes can be placed inside shaped steel frames. Lies lower than the sea or lake bottom and is then filled.

Dredging works

In dredging applications, such as ship launches, the use of materials such as Geotubes to provide a containment for dredged materials prevents them from returning to the dredged area. dredge. This reduces the annual dredging cost for the same area. Geotubes are often filled with sand and mud taken from the dredged area.

Geotube technology has been proven to be an effective method to help restrain the energy of ocean waves. Geotubes and sandbags sewn from geotextile are especially suitable for marine applications at low cost.

Geotube soft dike technology

Over the past 40 years, Geotube soft dike technology has been applied in hundreds of coastal protection works, recreating eroded beaches as well as creating new lands in the middle of the ocean.

Resisting and restraining the power of fierce waves is always an extremely difficult task. With more than 40 years of application, Geotube has been developed into a technology that helps prevent damage caused by storms, protect the coastal environment, build new structures, and even create islands. man-made in the middle of the ocean.

Soft dike solution

Besides the advantages of bringing economic benefits when restoring and protecting the sea, Geotube flexible dikes are also very environmentally friendly, contributing to protecting marine beauty.

Summary
In general, common applications of Geotubes include:

• Dykes protect the shore
• Offshore breakwater
• Anti-drift dike (groyne and wharf)
• Form artificial islands.
