Description
Technical field
It the utility model is related to civil engineering material technical field, especially novel high-strength geotechnical grid.
Background technology
Geotechnical grid is that a kind of geotechnical grid sheet material is had into 3 D stereo network structure simultaneously by the one kind connected and composed
And suitable for the civil engineering material of soil curing, after geotechnical grid is provided with slope and is banketed, run into rainwash
When, the soil body can be fixed in geotechnical grid, thin sand and soil will not be allowed to slide down, avoid the risk on landslide, while geotechnique
Cell compartment can play a part of strengthening road bearing strength, can effectively prevent road sinks, enhance the stability of road, but
It is that geotechnical grid still has problems and can cause negative consequence to construction quality.Existing geotechnical grid shortcoming is as follows：(1)
Although although many geotechnical grid referred to as honeycomb types, and non-critical honeycomb at present, due to the geotechnique of prior art
Cell compartment welds out a sealing wire, such as Chinese patent application using ultrasonic bonding on geotechnical grid piece
It is near-rhombic after the interconnection of geotechnical grid piece is reinflated shown in geotechnical grid in CN106592567A, contrasts hexagon,
The firm performance of quadrangle is greatly reduced, and the tensile strength between cell compartment is limited, influences the firm of the soil body after construction.For another example China is special
A kind of profit application double-deck geotechnical grids with drain function of CN106638555A, bilayer have the geotechnical grid of drain function,
Using the compactness that filler can be influenceed because of double layer hollow structure in being carried on basis, so as to influence base fixed；In slope protection works
Middle use, laterally laying can be reduced because of double-deck labyrinth current on slope to seepage velocity under slope, cause slope table protection geotechnique
Cell compartment stress increases, and sheet material fracture easily occurs and washes away dike slopes；Longitudinal direction laying causes geotechnical grid weld seam to be in stress point below cell compartment, easily
Snap the correct method for paving for not meeting geotechnical grid in slope protection works.(2) former cell compartment sheet surface is non-porous, can be because in engineering
Cell compartment occlusion relatively hinders the water body infiltration between cell compartment, meeting slopes caused by rainfall is accumulated in cell compartment especially in slope protection works
Gravity is excessive and causes to come down, and forms slope table runoff because slope table infiltration ability is relatively low, coombe occurs；As cell compartment includes
Water is larger to there is frost heave in the winter time, and cell compartment and slopes are damaged；
The content of the invention
The utility model solve technical problem be to provide a kind of novel high-strength geotechnical grid, make honeycomb type geotechnique's lattice
Room effectively firm soil, tensile capacity of cell compartment after engineering construction significantly improve, and tension is strong between width welding also causes cell compartment
Degree increase, extend the service life of geotechnical grid.
To achieve the above object, the utility model employs following technical scheme：
A kind of novel high-strength work cell compartment, including geotechnical grid piece and honeycomb is interconnected together by the geotechnical grid piece
Type grid, the cell compartment are provided with weld seam, and the weld seam forms a line of the geotechnical grid, and the cell compartment expands into
Hexagon honeycomb type.
Preferably, the width of the weld seam is a, and the distance of adjacent weld seam is e, the relational expression of satisfaction for 1.5cm≤a≤
0.5b。
Preferably, the weld seam is be arranged in parallel by more than two welding edges.
Preferably, it is provided with water permeable device in the cell compartment.
Preferably, the water permeable device is permeable circular hole.
Preferably, the cell compartment thickness is d, and the relational expression that d meets is d >=1.5mm.
A kind of novel high-strength geotechnical grid of the present utility model, is provided with weld seam, the weld seam on geotechnical grid piece
The a line of hexagon is constituted, is hexagonal honeycomb after connection expansion, because the stabilized structure of hexagon so that cell compartment energy
The ability of enough stability maintenance soil significantly becomes strong, and single-point stress when contrasting the wall scroll welding of prior art becomes wider weld seam
Stress so that the tensile capacity of cell compartment significantly improves.Advantage on geotechnical grid piece：1st, hexagon honeycomb structure be in nature most
Energy-conservation, strong mechanical structure, have given play to the bigger soil stabilization ability of cell compartment；2nd, adjacent cell compartment sheet material because set weld seam,
Cell compartment is changed into two points stress from single-point stress in slope protection works, and the tensile capacity between cell compartment significantly improves.

Embodiment
The utility model provides a kind of novel high-strength geotechnical grid, as shown in figure 1, in one of the embodiments,
The minimum unit of honeycomb type geotechnical grid is approximate hexagon, and the geotechnological lattice of overall honeycomb type are connected to become by geotechnological form piece
Room, in the present embodiment, weld seam is provided with geotechnical grid piece, weld seam includes the 11a of the sealing wire one and 11b of sealing wire two, sealing wire
One 11a and the 11b of sealing wire two be arranged in parallel, and it is wide that the distance between the wherein 11a of welding edge one and the 11b of welding edge two are defined as weld seam
Degree, the width of weld seam 11 be c, as shown in Fig. 2 the distance between adjacent weld seam be e, the relational expression of their satisfactions be 1.5cm≤c≤
0.5e, after the expansion of honeycomb type geotechnical grid piece, width weld seam becomes one of side of minimum unit, so whole expansion
It is afterwards hexagonal honeycomb, hexagon honeycomb structure is highly stable mechanical structure so that whole system is more stable, no
Easy glide, protect the soil body.Fig. 3 is the geotechnical grid deployed condition structure chart of prior art, with geotechnical grid of the present utility model
