Embodiment 1

[0032] An inflatable geotechnical bag, the geotechnical bag is composed of at least one geotechnical bag unit, and the geotechnical bag unit is a semi-closed structure composed of a top sealing material, a bottom sealing material 13 and a circumferential double-layer geomembrane 1; wherein, the bottom sealing The edge between the material 13 and the double-layer geomembrane 1 is closed, and the adjacent edge of the double-layer geomembrane 1 is treated with the edge 2, and the air hole 3 is provided on the edge 2; the double-layer geomembrane 1 and the The crimping is closed between the top sealing materials; the annular double-layer geomembrane 1 is provided with an inflation port 4 .

[0033] The geotechnical bag unit is a square structure.

[0034] The top sealing material is divided into 4 pieces, namely the top sealing material sheet 16, the top sealing material sheet 210, the top sealing material sheet 311 and the top sealing material sheet 412, wherein two adjacent mate...

Embodiment 2

[0040] The geotechnical bag described in embodiment 1 is applied to the slope protection structure, and the construction method is as follows:

[0041] Step 1. Level the base bearing surface, and spread the geotextiles on the base bearing surface in turn;

[0042] Step 2, open the inflation valve port 15, use the inflation device to inflate the ring to the double-layer geomembrane 1, close the plug air sleeve 16 to close the inflation valve port 15, until each geobag unit is a three-dimensional box shape;

[0043] The 3rd step, the top sealing material sheet 1 6, the top sealing material sheet 2 10, the top sealing material sheet 3 11 and the top sealing material sheet 4 12 are unfolded from the inside, and it is placed on the outside of the geotechnical bag, and then to the inside of the geotechnical bag Fill with earth and stone or water, stop when filling close to the height of the geotechnical bag, fold the top sealing material sheet 1 6 and the top sealing material sheet ...

Abstract

The invention discloses an inflatable geobag and a construction method thereof. The geobag is composed of at least one geobag units. Each geobag unit is of a semi-closed structure which is composed ofa top closing material, a bottom closing material and an annular double-layer geomembrane. The bottom closing material and the annular double-layer geomembrane are closed in a side pressing mode. Theadjacent edges of the annular double-layer geomembrane are subjected to side pressing treatment. Vent holes are formed in the pressed edges. The annular double-layer geomembrane and the top closing material are closed in a side pressing mode. An inflation port is formed in the annular double-layer geomembrane. The geobag is high in construction efficiency and can be automatically unfolded by inflating the annular double-layer geomembrane, and the geobag can be directly filled without mechanical or manual supporting. When soil is filled with the geobag, a powerful restraint function can be achieved on the soil by the annular double-layer geomembrane, and the soil strength is improved. The geobag is wide in application range, and suitable for the fields of foundation reinforcement, dyke slope protection, retaining wall construction, slope protection and revegetation and the like.

Description

technical field [0001] The invention belongs to the technical field of civil engineering and relates to a reinforcement method, in particular to an inflatable geotechnical bag and a construction method thereof. Background technique [0002] As a new type of soft soil green reinforcement material, geotextiles not only play a role in flood control and emergency rescue, but are also used in engineering practices such as foundation reinforcement, embankment protection slope, and retaining wall construction. However, traditional geotechnical bags are made of waste woven bags with soil, which has a single structure and small size. The production process requires a lot of manpower, and the construction efficiency is low, which restricts the promotion of geotechnical bags in actual projects. Contents of the invention [0003] Technical problem to be solved: In order to overcome the defects of the prior art and obtain a geotechnical bag with high construction efficiency, convenient...
