Description

A geotube bag reinforced with composite methods

Technical field

The utility model relates to the field of geotechnical pipe bags, specifically to a geotechnical pipe bag reinforced using a composite method.

Background technique

Geotechnical pipe bags were originally used in embankment projects. Due to their good filtration effect, they have been applied to environmental protection, agriculture and other fields. As people's research deepens, their application fields will become more and more extensive. The geotube bag dehydration and solidification method uses two dynamic factors, the filter structure of the equivalent pore size of the geotube bag and the liquid pressure in the bag, to cause water to seep out of the tube bag and sludge to remain in the tube bag during the dredging process. Thereby achieving the effect of reducing sludge volume.

Geotechnical pipe bags are generally provided with suture areas at both ends. After being filled with sludge, the end suture areas are prone to rupture due to the outward force of the sludge. Especially for large geotube bags, the longer the circumference and the higher the filling height, the easier it is for the end suture area to break, and the higher the strength requirements for the end sutures. Once the geotube bag ruptures, not only the mud will seep through out, thereby affecting the construction progress, and there will also be safety risks.

Utility model content

The purpose of this utility model is to provide a geotechnical pipe bag that uses a composite method to reinforce the seams at the ends of the bag body with strong stitching.

The reinforcing cushion layer, the first geotextile part, the second geotextile part and the reinforcing cushion layer are stacked and sewn together through sutures.

It can be seen from the above solution that by adding a reinforcing cushion layer in the suture part, it will help to improve the suture strength and firmness of the end of the bag body, avoid rupture of the end suture part due to filling with more filler, and help improve the geotechnical pipe. Extend the life of the bag and reduce safety risks.
