Abstract
The invention relates to a solid waste earthwork bag of engineering construction wastes, industrial wastes, stones, dregs and soils of mine tailings, and the like that have no chemical pollutions as well as an application method thereof in a foundation and a side slope. Available crushed solid wastes are directly put into the earthwork bags which are specified strictly, and the solid waste earthwork bags are then piled on the engineering construction foundation and the side slope according to a certain arrangement way and compacted layer by layer by a compacting device to form a building foundation or be used for reinforcing the side slope. As the solid waste soil body restricted and the vibration energy is consumed by the tensile force generated by the compression deformation of the earthwork bag, the whole strength and the shock absorption performance of the solid waste earthwork bag are improved. The solid waste earthwork bag is applied to foundation engineering, saves the resourcesand the land, reduces the vibration, prevents the disaster and the freeze thawing, is green and environment-friendly and has remarkable benefits.

Five, the specific embodiment
A kind of with solid waste earthwork bag and be applied to the method for construction project ground and side slope, its step is as follows:
(A) solid waste such as engineering construction (particularly city-building) discarded object, industrial waste, mining area tailings that will not contain chemical contamination are crushed to that 5cm is following (to be used for cold district, then therefrom rescreen except that the fine particle materials below the 0.075mm) solid waste 1 such as the stone after the fragmentation, slag, soil are packed in a series of geotechnique bag 2, and by the good sack of 6,7,8,9 take-up straps, the solid waste earthwork bag 3 of formation is stand-by;
(B) on the ground and side slope soil layer face of engineering construction,, and carry out soil layer by standard and handle with this soil layer of rolling compaction machine compacting;
(C) solid waste earthwork bag 3 of step (A) is transported and winches to engineering foundation and side slope place, place solid waste earthwork bag 3 by crisscross arrangement mode, interconnect between solid waste earthwork bag 3 sacks, to improve its globality, 4 usefulness engineering construction places, space soil between the solid waste earthwork bag 3 or broken solid waste 1 are filled.One deck rolls with rolling compaction machine, until the compactness 1.5-2.0g/cm that is compacted to designing requirement after laying and finishing
3Till;
(D) set by step the mode of (C) is successively constructed, and until to top layer, forms structure foundation or side slope protection body, is provided with surface protection 5 on each surface of ground and side slope.
The described geotechnique bag 2 of above-mentioned steps (A) be by admixture the black polypropylene material of 0.5-1% aging-proof agent make, uvioresistant, and can be durable, planar dimension is 40-100cm * 40-100cm.
With the related experiment result, the invention will be further described in conjunction with the accompanying drawings.
The Analysis on Mechanism figure that Fig. 1 increases for solid waste earthwork bag intensity.Solid waste earthwork bag uploading the whole generation of solid waste earthwork bag compressive strain under the pressure effect, causes the sack elongation, thereby produce a tension force T in sack after compacting.Sack tension force T plays an effect of contraction to the solid waste in the earth bag conversely, makes that the contact force N between the interior native stone granulate of bag increases.Because native stone body intensity comes from the frictional strength between native stone granulate in essence, contact force N increases between the soil stone granulate, and the frictional strength increase between promptly native stone granulate (meets law of friction F=μ N, μ: friction factor between native stone granulate), therefore, the integral anti-shearing intensity of solid waste earthwork bag increases.
The vibration damping of solid waste earthwork bag monomer is because under the vibrating load effect, the fricting movement consumed energy between the native stone granulate in the flexible modification of bag and the bag causes; Solid waste earthwork bag assembly vibration damping is that vibration is difficult to by the space between bag and the bag because discontinuous between the bag.
The space is bigger between the particle in the coarse granule solid waste earthwork bag, this geotechnique's bag is used for ground and slope reinforcement, water in the geotechnique bag lower soil or underground water can to rise to geotechnique's bag not inner because of capillarity, thereby can prevent freeze thawing at cold district.
According to indoor friction test, during criss-cross arrangement, the interfacial friction coefficient is greater than 1.0, generally between 1.05-1.2 between described solid waste earthwork bag layer and the layer.Therefore the solid waste earthwork bag stability of piling up can guarantee.
The method of described solid waste earthwork bag and application, be applicable to fields such as (comprising city-building, earthquake reconstruction, cold district) building, traffic, water conservancy, be specially house foundation, highway, railway, airport, harbour ground, dykes and dams, side slope, barricade etc.
