Description
Technical field
The utility model relates to a kind of multilayer block stone fill foundation dynamic replacement ruggedized constructions.
Background technique
With the development of economy, the expansion of Southwest Mountainous Areas infrastructure scale needs a large amount of level lands to solve land demand.
At present in Process of Engineering Construction, manually asked by what is filled out greatly to massif and the big digging of cheuch progress with solving construction land with making
Topic.Since heavy excavation explosion Rock And Soil certainly will generate a large amount of carbonate rock cubic metres of earth and stone.The carbonate rock rubble of generation, block stone are returned
It fills out in cheuch and is compacted by strong rammer or compaction technology, form artificial backfill ground as upper building supporting course,
There is a large amount of engineering practice.But the cultivated plant soil on massif surface layer, clay, sand etc., due to its springy texture, shearing strength is low, pressure
The features such as shrinkage is high is not easy as backfilling material, and gives it up and generate a large amount of disused soils.And it needs to find newly for it
Landfill place is likely to result in new environmental problem.
Summary of the invention
Technical problem to be solved by the utility model is: providing a kind of multilayer block stone fill foundation dynamic replacement reinforcing knot
Structure, the ground after dynamic replacement is reinforced can digest a large amount of discarded clays generated by Engineering Project Construction, while can
Solve random heap abandon clay and caused by soil erosion, can satisfy the bearing capacity demand that top structure (building) builds object, reduce because far
The engineering cost generated apart from transport disused soil, to solve problems of the prior art.
The technical solution that the utility model is taken are as follows: a kind of multilayer block stone fill foundation dynamic replacement ruggedized construction, including
Rock-fill layer, argillic horizon and waterproof bed course, the setting of waterproof bed course on surface, under on to being disposed with interlaced arrangement
Multilayer rock-fill layer and argillic horizon, multilayer rock-fill layer and argillic horizon are provided with more dynamic replacement piers.
Preferably, for above-mentioned rock-fill layer with a thickness of 2~3 meters, thickness of clay soil is 1~2 meter, and waterproof cushion thickness is
0.3m。
The utility model has the beneficial effects that compared with prior art, the utility model carries out consolidation process to fill foundation,
It is capable of digestion process and excavates a large amount of discarded clays that massif generates, avoid soil erosion caused by arbitrarily stacking, outside reduction waste
The engineering freight charges generated are transported, and design and specification can satisfy by the strength of composite foundation that soil is formed between dynamic replacement pier and pier
It is required that.
Detailed description of the invention
