Background technique
Be cured in situ: it is a kind of that solidification being carried out in situ to soil bodys such as weak soils using curing agent, make the soil body reach some strength or
Other requirements, to carry out treatment in situ to the soil body.China is improved in the solidification of the soil bodys such as dredging silt, Polluted Soil at present
Aspect has done a large amount of research, but remains in laboratory test, bench-scale testing so far, and it is real that large-scale engineering has not yet been reached
With the stage, while the recycling rate of the spoirs such as mud is far below level of developed countries, rivers and lakes dredging, dredging, work
Cheng Jianshe can generate the waste soils such as a large amount of mud, and the environmental problems such as transport, stacking, land occupation, fugitive dust are prominent.For asking above
Topic at this moment in engineering, is formed in situ crust layer using the technology of being cured in situ or plate body carries out shallow layer foundation processing, instead of cushion
Realize recycling for soil resource.
Grid, also known as steel grating, steel grating or flase floor are that band steel and torsion steel are welded, its main application of grid exists
Half space, aisle, ditch lid and step plate etc..It is also used in environmental protection equipment and sewage treatment etc., it is superior because of him
Property is more and more widely adopted.
Gap length between grid grizzly bar can be set according to the requirement of the mode and water pump of removing dirt, manually remove lattice
Grid gap is generally 16-25mm.Grid before setting pot or sedimentation basin generally uses 15-30mm, is up to 40mm.Grid equipment
It is generally used on the irrigation channel of sewage treatment or the entrance of Boosting pumping station collecting-tank, main function is larger in removal sewage
Suspension or floating material, to mitigate the processing load of subsequent water treatment technology, and play protection water pump, pipeline, instrument the effects of.
It is general using mechanical scarfing cinder mode when the grid quantity of slag of interception is greater than 0.2m3/d;When the grid quantity of slag is less than 0.2m3/d, people can be used
Mechanical scarfing cinder mode can also be used in work scarfing cinder mode.Applying for grid is answered in construction, design decoration, sewage treatment, engineering
Have been widely used with equal fields.
Soft soil foundation refers to the ground being made of mud, muck soil, rinse fill, miscellaneous fill or other high-compressibility soil layers
Base.This ground natural moisture content is excessive, and low bearing capacity is also easy to produce sliding or consolidation settlement under load action.It is soft soil roadbed
Processing intent be improve highway subgrade stability and bearing capacity, reduce sedimentation.At present frequently with cushion, pre- in engineering
The project cost of the processing of platen press and various displacement methods progress soft soil foundation, cushion and various displacement methods is very high, and constructs
Duration is longer, and the construction period of preloading method is longer, and the construction period is wanted on some provisional roadbeds and workbench basis
