Abstract
This utility model is that one has big rigidity solid geogrid, it is characterized in that being constituted agent structure by grid rib tape, injection node；Grid rib tape is connected with each other, in cube structure；Grid rib tape is made up of high-strength carbon steel wire, the high-strength polyethylene of outer wrapping and osculum；Consisting of injection node between grid rib tape, injection node has set injection pressure hole, uses ultrasonic bonding to reinforce grid rib tape junction by injection pressure hole.It is high that this structure has intensity, the advantage that rigidity is big, it is possible to be applicable to slope project or subgrade engineering, preferably plays the reinforced action of this structure.
Description
Art
This utility model relates to a kind of three-dimensional GSZ, especially relates to be applied in side slope or subgrade engineering
One there is big rigidity solid geogrid.
Background technology
At present, in slope project, subgrade engineering are built, it is typically employed in the soil body and adds doing of geosynthetics
Method, conventional such as GSZ.The mechanism of action of GSZ is exactly, and forms reinforced earth by grid with the soil body so that increase
Frictional force between grid and the soil body, can make soil strength be greatly increased and effectively prevent sedimentation；At some roadbeds or
The high strength composites such as the grid that the reinforcement engineering of dykes and dams is also commonly used, have easy construction, saving of labor, timesaving advantage.
Conventional GSZ is divided into plastic grill and fabric grid, two class grids to have its shortcoming, the letter of plastic grill technique
Single, but creep is relatively big, and intensity is relatively low；Fabric grid technique is loaded down with trivial details, and cost is more expensive；Chinese patent discloses Application No.
The solid geogrid of 200810100611.8, after this solid geogrid is laid in ground, can make stretching resistance, yield force,
Shearing force, interlocking power, frictional resistance significantly improve, but the most not solve intensity low for this grid, the problem that rigidity is little；Therefore I
Can obtain traditional grid and there is following problem: 1. grid intensity is low, and rigidity is little, particularly at complex geological condition
Under, it is difficult to play good strengthening action；2. general grid is planar structure, although can play one at formation reinforced earth and be set for
With, but poor in terms of preventing vertical sedimentation and horizontal displacement；3. there is some solid geogrid and form reinforced structure,
Make can not well be formed between the soil body entirety because lacking infiltration structure；4. GSZ causes joint owing to node processing is improper
Point is torn, and makes overall structure be destroyed.
Summary of the invention
In order to solve in slope project and subgrade engineering, tradition GSZ also exists that intensity is low, rigidity is little, drainage
Difference and reduce vertical sedimentation and the problem such as horizontal displacement is inconspicuous, devising one has big rigidity solid geogrid, passes through
This grid can well solve a tradition GSZ difficult problem in the application.
This utility model is that one has big rigidity solid geogrid, it is characterized in that by grid rib tape, injection node structure
Become agent structure；Grid rib tape is connected with each other, in cube structure；Grid rib tape is by high-strength carbon steel wire, the height of outer wrapping
Strength polyethylene and osculum composition；Consisting of injection node between grid rib tape, injection node has set injection pressure hole, passes through
Grid rib tape junction is used ultrasonic bonding to reinforce by injection pressure hole.
As improvement, high-strength carbon element intensity of steel wire is more than 2000MPa；Steel wire bunchy structure, three compositions are a branch of；Grid muscle
Band can adjust the number of bundle according to actual requirement of engineering intensity.
As improvement, grid rib tape arranges osculum between high-strength carbon element steel tendon, and osculum is positioned in grid rib tape
Position, portion.
As improvement, injection node is cube structure, is entered by whole grid rib tape junction parcel；Injection node is adopted
Make with high-strength resin material.
As improvement, osculum is provided with plastic wire, and assume diamond in shape structure.
The beneficial effects of the utility model: GSZ uses stereochemical structure so that it is can be entrenched in one with ground
Rise, preferably play reinforced action, and be prevented from settlement of foundation and displacement change；Grid rib tape is by arranging high-strength carbon element
Steel tendon, substantially increases the strength and stiffness of GSZ, it is possible to is GSZ in the case of suffering abnormal external force, also can
Enough well playing reinforced action, the osculum that grid rib tape is laid can make soil pore water flow wherein, makes reinforcement
Material and the soil body form an entirety；Injection node uses cube structure, and uses high-strength polyester resin material to make, and prevents
Destruction of a node between grid rib tape；Ultrasonic bonding is used to reinforce, further to joint junction by injection pressure hole
Point protection.

Detailed description of the invention
With reference to the accompanying drawings: this practicality is to be constituted agent structure by grid rib tape (1), injection node (3)；Grid rib tape (1) phase
Connect, in cube structure；And be by high-strength carbon steel wire (12), the high-strength polyethylene of outer wrapping with grid rib tape (1)
(14) form with osculum (11)；Consisting of injection node (3) between grid rib tape (1), injection node (3) has set injection
Pressure hole (2), uses ultrasonic bonding to reinforce grid rib tape (1) junction by injection pressure hole (2).
As improvement, high-strength carbon steel wire (12) intensity is more than 2000MPa；High-strength carbon steel wire (12) bunchy structure, three
Root composition is a branch of；Grid rib tape (1) can adjust the number of bundle according to actual requirement of engineering intensity.
As improvement, grid rib tape (1) arranges osculum (11) between carbon steel tow, and osculum (11) is positioned at grid
Rib tape (1) medium position.
