Embodiment 1

[0028] Such as Figure 1-Figure 3 As shown, a geonet frame includes a geonet layer 4, and several layers of geonet layers 4 are stacked and bound by ropes 2 to form a frame body;

[0029] The geonet layer 4 includes several geotechnical strips 1 , and adjacent geotechnical strips 1 are bound by ropes 2 to form the geonet layer 4 on the same plane.

[0030] The geotechnical strip 1 is composed of a plurality of interconnected similar spherical soil balls 3, and each soil ball 3 is provided with a filler.

[0031] The geostrip 1 includes a long bag, the two ends of which are closed, and the long bag is provided with fillers and bound by several ropes 2 to form several interconnected similar spherical soil balls 3 .

[0032] The long bag is preferably a long PP woven bag (polypropylene woven bag containing TH), which has high strength, and its filling is realized by machine.

[0033] When several layers of geonet layers 4 are stacked, each soil ball 3 in the upper geonet layer ...

Embodiment 2

[0037] An application of the above-mentioned geonetwork frame in foundation reinforcement is as follows:

[0038] Such as Figure 4 as shown,

[0039] According to the geological conditions of the foundation 7 and the load level acting on the foundation, the scope and depth of the foundation pit 6 to be excavated are determined, and then the foundation pit is excavated according to the conventional foundation pit excavation process.

[0040] Fill the excavated soil or other construction waste into the prepared long strip PP woven bag, and then tie the ropes 2 equidistantly outside the long strip PP woven bag, so that the filling inside the long strip PP woven bag becomes one by one. The independent soil ball 3 is to complete the making of the geostrip 1; put the prepared geostrip 1 into the foundation pit 6, and note that the geostrip 1 in the same layer needs to be placed in the same direction, and then connect the geostrip 1 with the connecting rope 2. The geotechnical str...

Embodiment 3

[0043] An application of the above-mentioned geotechnical network frame in slope reinforcement, specifically:

[0044] Determine the slope surface of the slope according to the geological conditions of the slope and the load level acting on the slope;

[0045]Sequentially close to the slope surface of the slope to form a geonet frame with the same slope as the slope surface, and install it in front of the slope: fill the excavated soil or other construction waste into the prepared long strip PP woven bag, and then place it in the Bind the ropes 2 equidistantly around the perimeter of the long strip-shaped PP woven bag, so that the fillers inside the long strip-shaped PP woven bag become individual soil balls 3, which completes the production of the geostrip 1; make the prepared geostrip 1 close to For slopes, pay attention that the geostrips 1 in the same layer need to be placed in the same direction, and then use the connecting rope 2 to connect and fix the geostrips 1 in the...

Abstract

The invention relates to a geotechnical network frame, which comprises geotechnical network layers which are stacked and bundled by ropes to form a network frame body. The geotechnical network layer comprises a plurality of geotechnical strips, and adjacent geotechnical strips being bundled by ropes to form a geotechnical network layer on the same plane. The geotechnical network frame and the application thereof provided by the invention can solve the problems of poor mechanical performance and long manufacturing time after geobag connection in the prior art. The structure is stable, high bearing capacity and beneficial shock absorption effect on engineering are achieved, the bearing capacity of the foundation or the stability of a slope or a retaining wall is effectively improved, and engineering disasters such as foundation instability, landslide and the like are greatly reduced.

Description

technical field [0001] The invention relates to the technical field of engineering reinforcement, in particular to a geotechnical network frame and its application. Background technique [0002] All over the world today, various types of infrastructure are being built or have been built, and many projects will involve the stability of naturally weak foundations or slopes. In such engineering situations, foundation reinforcement and slope treatment are required to ensure the stability of the foundation and slope and the safety of the project. The stability of engineering foundation often plays a key role in engineering quality and safety. Our country has a vast territory and includes many topography and landforms, thus forming many natural slopes. In various infrastructure constructions such as water conservancy projects, tunnel projects, and expressway projects, many artificial slopes will also be formed due to manual excavation. , and the stability of the slope is not onl...
