Description
Technical field
The utility model relates to civil engineering, relates in particular to a kind of composite reinforced ground.
Background technology
The earthquake of Tai Wanji-collection, China's Wenchuan earthquake, Japanese slope shake celestially and the earthquake calamity data such as U.S.'s Northridge earthquake show, geosynthetics has certain anti-seismic performance.The geotechnical engineerings such as roadbed, side slope and embankment are used the more conventional reinforced soil with geosynthetics structures such as geotextiles, geo-grid mostly, and this technology is relatively ripe, is used widely in the world.Quantity research shows greatly, and reinforcement effects and the filling property of these two dimensional surface muscle materials have much relations.While being combined such as the planar grille filler larger with particle, can produce very large intensity, still, when the cohesive soil less with particle is combined, intensity likely reduces on the contrary.There is certain defect in two dimension muscle material, makes the scope of application of the two-dimentional muscle material very limitation that becomes.If purely use three-dimensional geotechnical grid as the reinforcement material of ground, cost must increase considerably.Junked tire and geotechnical grid have that tensile strength is high, durability, resistance to wear, the premium properties such as anti-aging, and construction fast simple, cost is extremely cheap, environmental protection.
Utility model content
The object of the invention is just the shortcoming and defect existing for prior art, and a kind of composite reinforced ground is provided, and its concrete technical scheme is as follows:
A composite reinforced ground, is characterized in that: comprise level is staggeredly placed in ground reinforced structure a (1) and reinforced structure b (2) from top to bottom.Described reinforced structure a is that 2 and above tire (5) are interconnected and formed by tyre surface; Described reinforced structure b is geotechnical grid, and the packing material of described ground is building filler (3).
Described tire (5) one sides have tyre bead, and opposite side is without tyre bead, and in the side direction without tyre bead.
Described tire (5) is fixedly connected with by bolt (4), forms cellular or net structure.
Distance between described reinforced structure a (1) and reinforced structure b (2) is not less than the thickness of reinforced structure a (1) or reinforced structure b (2), is not more than 50cm.
The utility model is usingd and is excised the junked tire of a sidewall and geotechnical grid as Reinforced Foundation material, has not only overcome the shortcoming of two dimensional surface muscle material scope of application limitation, and as Reinforced Foundation material, has compared with geotechnical grid with pure, also greatly reduces cost.Geotechnical grid and junked tire are all three-dimensional structures, and geotechnical grid sidewall not only can increase filler lateral restriction, can also reduce by vertical frictional force the sedimentation of filler, thereby improve bearing capacity of foundation soil.In order to facilitate filling and compacting filler, while laying waste netted old tire, make the one side of its sidewall not having upwards.Tire not only can increase the lateral restriction to filler, and residue one sidewall can also be by the friction with filler, the lateral deformation of restriction filler, thus reach the object that improves bearing capacity of foundation soil, and economic environmental protection.
The foundation structure that the utility model provides is comprised of upper and lower multilayer planar reinforced structure layer, first at ground basal part, be equipped with certain thickness building filler compaction in layers, as bed course, then from top to bottom successively equidistantly or staggered junked tire layer and the geotechnical grid laid of unequal-interval.In order to facilitate filling and compacting filler, while laying waste netted old tire, make its side that there is no sidewall upwards.Inside and outside muscle material, gap and interlamellar spacing are filled up building filler fully compacting, make it by increasing muscle material and the frictional force of building filler and the globality that snap-in force improves whole composite reinforced ground.
Working mechanism:
Reinforced Foundation for the junked tire layer of layering interlaced arrangement successively and geotechnical grid, when Reinforced Foundation is subject to load action, because muscle material has limited the lateral deformation of filler to the lateral restriction of filler, be equivalent to apply subsidiary stress to filler, increased lateral restraint stress (minor principal stress
), the large main stress bar while making foundation failure
obtain corresponding raising, thereby improve the supporting capacity of Reinforced Foundation.After soft foundation reinforcement, the rigidity of Reinforced Foundation increases substantially with respect to the rigidity of plain soil base, and when Reinforced Foundation and plain soil base are subject to same load, the deflection of Reinforced Foundation also reduces a lot accordingly.The more important thing is, the interaction between muscle material and filler, mainly comprises frictional force and the snap-in force of muscle material interface and filler, and the very big globality that has increased Reinforced Foundation structure, is also significantly improved the stability of ground accordingly.
Compare with the Reinforced Foundation structure of conventional geosynthetics, the present invention has following advantages and good effect:
1) material of main part of Reinforced Foundation is waste netted old tire and geotechnical grid, is easy to compacting, has overcome the defect that may damage because foundation deformation is excessive.
2) Reinforced Foundation structure have durability, anti-aging, resistance to wear, the premium properties such as fatigue resistance is stronger.
3), when reinforcement material is embedded in and bears pressure in the soil body, tensile strength is very much not easily broken, and can excite the lateral restriction to filler, thereby makes Reinforced Foundation structure bear larger bearing capacity.
4) simple in structure, the easy construction, with low cost of Reinforced Foundation.
5) Reinforced Foundation structure makes full use of discarded object and on-the-spot earth material, reduces environment pollution and floor space.
6) the utility model limits the lateral deformation of ground to a great extent, increases the shear strength of soft foundation and the globality of structure, improves the bearing capacity of soft foundation, reduces sedimentation, improves soft foundation anti-seismic performance, economic environmental protection.

The specific embodiment
Below in conjunction with 1 pair of the utility model of drawings and Examples, be elaborated:
Embodiment 1
The step of laying this ground is as follows:
1) first at ground basal part, lay certain thickness building filler and use mechanical compaction in layers, as bed course.
2) on the bed course of compacting, lay after any one reinforced structure, should be in time inside and outside muscle material gap filling building filler, the time interval should be no more than 48 hours, and the packing material size of filling reinforced structure gap should not be greater than 2cm.
3) lay and space be full of filler reinforced structure above continue to add building filler, and use mechanical compaction in layers, reach the designing requirement of interlamellar spacing.Thickness requirement after interlamellar spacing filling compaction is not less than the thickness of any one reinforced structure as far as possible, but should not be greater than 50cm, and with interior packing material size, should not be greater than 2cm from muscle material 10cm.
4) on the filler of compacting, re-lay another kind of reinforced structure, then building filler compacting are filled in gap inside and outside reinforced structure.
5) repeat successively said process, the equidistant or unequal-interval of layering is staggered lays reinforced structure, and gap and interlamellar spacing filling building filler with mechanical ramming, till reaching the designing requirement of ground always inside and outside reinforced structure in time.The Reinforced Foundation structure finally obtaining as shown in Figure 1.
