Description
Technical field
The weak soil and sandy soil subgrade strengthening part in civil engineering are the utility model is related to, more particularly to a kind of high intensity is high
The overall geotechnical grid of water penetration.
Background technology
In civil engineering construction, be frequently run onto inferior soil geological state, especially the soft thin sand and soil of north of China and northwest,
Powder fine sand, collapsible loess, the white bind of Southern Mountain Areas of China etc., fill of being repaired the roads under this geological state is very intractable thing.
Such soil property, harder when drying, rainwater arrives to meet water softening, is lost in quickly, it is difficult to common reinforcing is carried out,
Easily embankment is caused to cave in.General means are that solved using the method for soil removal and replacement embankment, but the cost of soil removal and replacement embankment is very high, haulagman
Measure very big.Newest method is reinforced using geotechnical grid, and geotechnical grid is as a kind of reinforcement with certain altitude
Reinforcement material, so-called " deep ground " platform effect is formed, the bearing capacity of this kind of soil property can be greatly improved, directly using local soil
Make filler, filled out without changing, for the enhancing of soft foundation roadbed, side slope protection, reinforced earth bulkhead, dam reinforcement etc., achieved
Preferable effect.
The geotechnical grid of prior art is polyethylene or polypropylene plastics sheeting permutation and combination and connected at node
Alveolate texture together.
Using the geotechnical grid of polyethylene extrusion sheet, by ultrasonic welding technique by the weldering spaced apart of adjacent two panels
Pick up and, after the full wafer tensioning expansion that multi-disc is welded and linked together, present cellular.Using polyethylene extrusion sheet
Geotechnical grid tensile strength is not high, and the node tearing toughness of ultrasonic bonding is than relatively low；Moreover, sheet material is waterproof, on sheet material
The percent opening for boring osculum can not possibly be too many, the possibility of ponding be present.
Using the geotechnical grid of polypropylene extrusion sheet, thin slice is formed by reheating stretching, passes through longitudinal joint-cutting U-shaped steel
The modes such as nail inserting, rivet clasp, heat seal form alveolate texture.Using polypropylene extrusion sheet geotechnical grid sheet material tension
The tear resistance of intensity and node is also poor, and the completely impermeable shortcoming that presence can not overcome.Because polypropylene foil
Material is easily torn along draw direction, can not be punched, then can not draining, this shortcoming directly affects many requirement of engineering and strictly controls
Filler processed, can only the expensive filler such as filler particles shape cobblestone, it is at all unrealistic in many places using this kind of filler.
Open defect existing for the geotechnical grid of prior art, have a strong impact on subgrade engineering quality.Node tearing toughness
Not high, machinery filling and cal rolling construction have node tearing destruction often, fail to form honeycomb, and whole reinforcing body loses
Effect.Sheet material also forms the metope of " being waterproof " in the soil body, laterally at all can not draining, and the water being rich in the soil body can be at this
Some small runoffs are formed on a little metopes, these small runoffs can wash away fine particles in the soil body, so that the soil body
Compactness substantially reduces, cause engineering occur it is a certain degree of collapse, depression etc., or even cause whole project failure.
The content of the invention
The problem of existing for the geotechnical grid of prior art, the utility model is proposed a kind of geotechnique of new structure
Cell compartment, the honeycomb network structure to be formed is connected through interspersed by using high intensity seepy material, enhances tensile strength, section
Point tearing toughness and node reliability, and there is full width face water permeability, better conform to the building work of weak soil and sandy soil roadbed
Journey.
A kind of high intensity high water-permeability entirety geotechnical grid is the utility model is related to, by a plurality of geotextile band side by side
Form, every geotextile band undulate shape, the crest location of two adjacent bands is mutually butted, and it is netted to form honeycomb
Structure；The crest joint of two adjacent ribbons, along the parallel puncture circular hole of the row of crest Top section arrangement two, each column punctures circular hole
In it is relative pass through two hard nylon yarns in the figure of eight, the two hard nylon yarns passed through connect adjacent two bands
Form the node of connection.
Described geotextile band is made of the high polymer fiber of high-tensile, width 20-500mm,
Thickness 0.5-5mm, grammes per square metre 100-1000g/m2.Distance is staggered described geotextile band node at equal intervals,
Spacing distance is 100-1000mm.
The utility model has very high tensile strength (60KN/m~200KN/m) using strip tape made of geotextile
With good water permeability (vertical permeability coefficient >=2.0x10-3Cm/s), the interspersed semi-rigid bone formed of hard nylon yarn is utilized
Frame node has preferable tear resistance, constitutes the geotechnological lattice of the permeable overall honeycomb network structure in high intensity full width face
Room, had broad application prospects in weak soil and the civil engineering of sandy soil subgrade strengthening.
