Abstract
The utility model relates to a four-dimensional warp knitting civil grille. A plurality of transverse grid bars and a plurality of vertical grid bars form a latticed structure, each lattice is rectangular, and nodes of the transverse grid bars and the vertical grid bars are fixed by binder yarns. A first inclined grid bar is arranged at one diagonal line position of each rectangular lattice, and the first inclined grid bars are mutually parallel. A second inclined grid bar is fixedly arranged at the other diagonal line position of each rectangular lattice, and the second inclined grid bars are mutually parallel. The four-dimensional warp knitting civil grille is formed into a two-dimensional latticed structure by the transverse grid bars and the vertical grid bars, the first inclined grid bars and the second inclined grid bars are arranged in the lattices of the grille, and therefore the grille is formed into a four-dimensional structure. The peel strength of the nodes is enhanced, so that the whole grille is not easily deformed.
Description
Technical field
The utility model relates to a kind of road construction reinforcement material, and is particularly four-dimensional through compiling the building grid.
Background technology
Quick sustainable growth along with Chinese national economy; The communication of China has also got into a flourish stage; The thing followed is that people also have higher requirement to highway construction; Topmost performance is handling capacity, supporting capacity, traveling security and the comfortableness etc. of road, and this just requires us in the highway design and construction, for designed output, construction technology, construction quality and managerial skills higher standard is arranged all.But be accompanied by the development of these high standard advanced roads; Some have also appearred than stubborn problem; Particularly, make high-grade highway in building, run and safeguarding, many problems can occur because the most of regional topography and geomorphologies of China are complicated, and geological condition is relatively poor.Such as in the infrastructure of road, regular meeting runs into the situation of on ground, building embankment or side slope.How to guarantee the stability of these embankments or side slope, just become present urgent need solution and perplex one of difficult problem of numerous engineers and technicians.
Solving at present the effective method of this difficult problem is to adopt reinforced earth technology.Reinforced earth is a kind of compound soil body that in soil, adds reinforcement material and form.In soil, add the intensity that reinforcement material can improve the soil body, strengthen the stability of the soil body.Reinforced earth technology is since producing, and its technical superiority, remarkable economical property and extensive applicability make its numerous engineerings field obtain great popularization development and application at home and abroad.
Construction in road has obtained significant progress to GSZ as reinforcement material, and has solved many technical barriers.GSZ is that the activities through uniqueness makes the long-chain hydrocarbon molecules of polymer arrange again in line along draw direction; Thereby have advantages of higher tensile strength and a lower elongation per unit length; Can produce the plate body effect when it and soil matrix are combined into one when whole, reduce differential settlement.The tensile strength of reinforcement reinforcement GSZ is very big, has approached mild steel, adds the locking action of eyelet to native stone; Restricted laterally moving of native stone, formed good interlock action, added the soil body and grid skin friction and the passive hindrance function of grid rib and node; Strengthened GSZ anti-ability and shear resistance dialled in soil; The incarceration locking action of rubble in the grid square hole prevent to produce excessive permanent deformation and fatigue failure, owing to can distribute load effectively; Prevent that ballast aggregate runs off and subgrade deformation, improves the stability of roadbed.The GSZ of present stage is owing to the restriction on technology and the equipment, and its node peel strength has only 2-4KN/m, and the mesh size generally can only reach 20mm * 20mm; This can satisfy the rubble locking action under the general condition; But for the engineering of some high requests, because the restriction of node peel strength, or the restriction of sizing grid; General GSZ just is difficult to reach engine request to the incarceration locking action of rubble; Cause the action effect of GSZ poor, therefore, be necessary to develop the high GSZ of node peel strength to the field of some high standard engineering.
The utility model content
The utility model provides a kind of node peel strength high, on-deformable four-dimensional through compiling the building grid in order to solve defective and the deficiency that above-mentioned prior art exists.
The technical scheme of the utility model: a kind of four-dimensional through compiling the building grid; Constitute fenestral fabric by some horizontal grizzly bars and vertical grizzly bar; Each grid is a rectangle; Laterally grizzly bar adopts bundled yarn to fix with the node place of vertical grizzly bar, and one of them diagonal positions of said each rectangular mesh all is set with the first oblique grizzly bar, and the first oblique grizzly bar is parallel to each other; Another diagonal positions of each rectangular mesh all is set with the second oblique grizzly bar, and the second oblique grizzly bar is parallel to each other.
Preferably, described horizontal grizzly bar is by three one thread Shu Zucheng, and described vertical grizzly bar is by three one thread Shu Zucheng, and the first oblique grizzly bar and the second oblique grizzly bar are at node place and yarn beam overlap joint and adopt bundled yarn to fix.
The utility model adopts following method to make: laterally grizzly bar, vertical grizzly bar, the first oblique grizzly bar, the second oblique grizzly bar are selected the high-strength polyester industrial long filament respectively for use; Bundled yarn is selected polyester FDY filament for use; Place the enterprising braiding of passing through of tricot machine make and the grid grey cloth, handle through PVC slurry impregnation technology again after grey cloth makes and making terylene warp knitting geogrid finished product.
The utility model constitutes the two-dimensional grid structure by horizontal grizzly bar and vertical grizzly bar, the first oblique grizzly bar and the second oblique grizzly bar is set in the grid grid and then constitutes four-dimensional structure, has improved the node peel strength, makes grid integral body not yielding.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further detailed explanation, but be not restriction the utility model protection domain.
As shown in Figure 1; A kind of four-dimensional through compiling the building grid; Constitute fenestral fabric by some horizontal grizzly bars 1 and vertical grizzly bar 2, each grid 5 is a rectangle, and laterally grizzly bar 1 adopts bundled yarn to fix with the node place of vertical grizzly bar 2; One of them diagonal positions of said each rectangular mesh 5 all is set with first oblique grizzly bar 3, the first oblique grizzly bars 3 and is parallel to each other; Another diagonal positions of each rectangular mesh 5 all is set with second oblique grizzly bar 6, the second oblique grizzly bars 6 and is parallel to each other.
Described horizontal grizzly bar 1 is made up of three one thread bundles 4, and described vertical grizzly bar 2 is made up of three one thread bundles 4, and the first oblique grizzly bar 3 and the second oblique grizzly bar 6 are at node place and yarn beam 4 overlap joints and adopt bundled yarn to fix.
