Description
Technical field
The present invention relates to a kind of bracing or strutting arrangement of Extra-Deep Foundation Pit, relate in particular to the two limb steel reinforced concrete combination of a kind of large-tonnage environmental protection braced structures.
Background technology
Be accompanied by the great development of urban construction, excavation of foundation pit has been tending towards large-scale and the large degree of depth.And wherein space enclosing structure plays key effect to deformation control of foundation pit.The form of structure that foundation ditch supports is of a great variety, and applying at present more is that steel supports and concrete support.
One, steel supports
Existing steel supports main specifications Φ 600, and Φ 609, and Φ 630, and Φ 800, Φ 820 etc., and ingredient comprises: steel support, fixed end, movable end.Although steel supports, there is the advantages such as installation, dismounting is convenient, handling safety is practical, be widely used at present in small-scale pit and subway work.But steel supports because bearing capacity is little, particularly, a little less than side direction anti-pressure ability, cannot meet the requirement of large foundation ditch, deep foundation ditch long support supporting.For ultra-large type deep-foundation pit engineering, steel supports because himself defect is difficult to meet the demands.Concrete reason is as follows:
On the one hand, example Φ 609 steel support approximately 300 tons of ultimate bearing capacities, because its bearing capacity is limited, need to meet the stable requirement of foundation ditch by reducing steel support arrangement spacing, thing followed problem is, little again little of the working space of excavation of foundation pit under intensive steel back-up environment, cut the earth and unearthed difficulty very large, meanwhile, the installation that hangs that lower floor's steel supports also bothers very much.On the other hand, steel supporting section moment of inertia is little, and a little less than side direction anti-pressure ability, axial compression poor stability, cannot meet the requirement of ultra-large type deep foundation ditch long support supporting.
Two, concrete support
Existing concrete support, due to the feature such as have that supporting capacity is strong, rigidity of section is large and non-deformability is strong, is therefore widely used in foundation ditch.Concrete support and steel support the mode being combined with successively and also by more base pit engineering, are adopted, and wherein, foundation ditch first supports and adopts concrete support, and some roads, bottom support and adopt steel to support.But existing concrete support is because its speed of application is slow, construction cost is high, dismounting is difficult, environmental effect is large and the defect such as the wasting of resources, current application is also subject to certain restrictions.The defect imbody of existing concrete support is as follows:
A. speed of application is slow.A series of flow processs such as concrete support construction needs through tying up muscle, formwork, builds, maintenance and dismounting, speed of application is slow.
B. remove difficulty.The modes such as the dismounting of concrete support need to adopt and cut, explosion, cutting, time-consuming taking a lot of work.
C. environmental effect is large.The demolishing process of concrete support is accompanied by a large amount of noises, dust, large on surrounding enviroment impact.In urban district, forbidden demolition blasting.
D. the wasting of resources.Concrete support remove to need a large amount of artificial, mechanical, and material cannot have enough to meet the need use, causes the wasting of resources.
In sum, existing braced structures all exists various defects, is difficult to meet the requirement of engineering of ultra-large type deep-foundation pit engineering and the requirement of environmental protection.Therefore, how to provide a kind of requirement that had both met large foundation ditch long support, the two limb steel reinforced concretes combination of the large-tonnage environmental protection braced structures that meets again the requirement of assembling and disassembling convenience, energy-conserving and environment-protective is those skilled in the art's technical problems urgently to be resolved hurrily.
