Problems solved by technology

[0003] For example, the Chinese invention patent (notification number: CN109853513B) disclosed a geocell in 2021, which improves the connection strength by double fixed connection of cable ties and card slots at the joints of adjacent geocells; but a single unit The lateral force, tensile and torsional properties of the grid still need to be improved
[0004] In addition, in the prior art, geocells are generally welded by ultrasonic welding of PP and PE material pressure plates. A lot of manpower and material resources, resulting in a certain waste of resources

Embodiment 1

[0061] to combine image 3 and Figure 4 As shown, a new type of geocell with a winged nesting structure is formed by welding and nesting multiple sets of first wing plates 2 and second wing plates 3 nested with each other. The left side of the first wing plate 2 , the ratio of the right waist to the lower bottom is 1:2, the thickness is 0.2cm, and the opening size of the gap 4 is 0.5cm. The left and right waists of the first wing plate 2 are not all vertical to the bottom, and the waist has a small amount of inclination to facilitate folding.

[0062] The left and right waist ratio of the second wing plate 3 is 7:5, the ratio of the upper bottom to the lower bottom is 1:2, and the thickness is 0.2cm. Each pair of first wing plates and second wing plates are combined to form a diamond-shaped unit cell, and multiple unit cells are connected to form a three-dimensional network structure.

Embodiment 2

[0064] The difference between this embodiment and the first embodiment is that the ratio of the left and right waists of the second wing plate 3 is 7:5, and the ratio of the upper bottom and the lower bottom is 1:3.

Embodiment 3

[0066] The difference between this embodiment and the first embodiment is that the ratio of the left and right waists of the second wing 3 is 7:5, and the ratio of the upper bottom and the lower bottom is 1:4.

Abstract

The invention discloses an earthwork standard room with a wing type nested structure and a processing and installing method thereof, the earthwork standard room is formed by connecting a plurality of earthwork standard units in an array arrangement mode, each earthwork standard unit is formed by nesting and welding a unit body, a first wing plate and a second wing plate, and the first wing plate and the second wing plate are nested with each other; the pair of first wing plates and the pair of second wing plates form a three-dimensional structure at an opening of the unit body in a mutually nested manner, the first wing plates and the second wing plates supplement each other, the first wing plates provide transverse support for the structure, the second wing plates provide vertical counter force, and meanwhile, holes are uniformly formed according to structural characteristics to meet the drainage requirement; the first wing plate is quadrilateral, an r-shaped notch is formed in the middle of the top edge of the first wing plate, and the second wing plate is trapezoidal; due to the arrangement of the nesting structure, the geocell has the advantages of being large in pulling force, high in strength, not prone to cracking and long in service life, and has good drainage performance.

Description

technical field [0001] The invention relates to the technical field of geogrids, in particular to a geogrid with a winged nesting structure and a processing and installation method thereof. Background technique [0002] The geocell is a grid cell structure formed by HDPE or PP copolymer wide band, which is welded or riveted. It can expand and contract freely, and can be collapsed during transportation. When used, it is opened and filled with earth, stone or concrete materials to form a structure with lateral and large rigidity. It can be used as a cushion to deal with weak foundations and increase the bearing capacity of the foundations. It can also be laid on slopes to form slope protection structures, and it can also be used to build retaining structures, etc. [0003] For example, the Chinese invention patent (notification number: CN109853513B) disclosed a geocell in 2021, which improves the connection strength by double fixed connection of cable ties and card slots at t...
