Description
Technical field
The invention belongs to brick or concrete duct fields, and in particular to a kind of Geogrid Reinforced Soil work filling-material structure and construction method, especially
It is related to the geotechnical filling structure and construction method of a kind of grid reinforcement steel slag+rubber grain.
Background technique
Since sandy gravel is increasingly short, need to find new geotechnical filling.Currently, with the continuous development of industry, largely
Trade waste constantly generate, wherein there are some wastes are reusable, such as by-product in steelmaking process --- steel slag
With the solid waste of auto industry --- waste tire.
Steel slag cannot such as be efficiently used, greatly by the second largest waste of metallurgy industry that a variety of carbon compounds form
It measures heap to abandon, not only land occupation resource, also pollutes the environment.Steel slag quality is heavier and harder, and internal voids are larger, has and sand
The similar property of soil.Steel slag is applied to geotechnique's backfill and not only reduces the waste of land resource, while also reducing solid waste
Pollution.
China's tire yield continuous 10 years at the forefront in the world, and the waste tire generated every year is also global first, 2015
At 3.3 hundred million or so, weight is sharply increased up to 12,000,000 tons, and every year with double-digit speed for year national waste tire yield
Add, at a kind of new " black pollution ".Due to tire debris lightweight, elasticity is good, good water permeability and durable, can promote roadbed
The intensity and permeability of the soil body.
In unfavorable foundation processing or rebuilding old road, TGXG can improve rapidly foundation bearing capacity, accelerate construction
Progress；The development of soft base location settling amount is controlled, is shortened the construction period, TGXG plays soil mass consolidation, improves globality, is equivalent to
Reinforcing bar in concrete.The mechanism of TGXG compacted soil is present among the interaction of grid and soil.It can generally be summarized as
The rubbing action of grid surface and soil；Grid eyelet acts on the locking effect of soil and the passive resistance of grid rib, can be sufficiently
The particle lateral displacement of soil is constrained, so that the self stability of the soil body is substantially increased, to the consolidation effect of soil, hence it is evident that be higher than
Other geotextiles.
The major trunk roads in some cities are higher to the intensity requirement of the soil body while also wanting in the retaining wall infrastructure at harbour
Construction noise is reduced, construction efficiency is improved, effective solution of the present invention soil strength not enough and in work progress is brought
Noise；In the construction on bay basis, using steel slag as aggregate, the intensity of the soil body is effectively enhanced, while taking two-way
Grid is laid in steel slag, provides effective stress guarantee in both direction in length and breadth.
The filler of Fill Reinforced With Geogrids is substantially sandy gravel at present, but sandy gravel is increasingly short, therefore, using discarded wheel
Tire particle and discarded steel slag form steel slag+rubber grain geotechnical filling and solve the problems, such as that sandy gravel is increasingly short；Moreover, at present
Foundation treatment technology majority there is a problem of that maintenance difficulties are high after engineering cost is high, construction is complicated and processing.TGXG,
Waste tire particle and discarded steel slag cost are cheap and easy for construction.
