Description
Technical field
The utility model relates to underground pipe gallery technical field of construction, and in particular to a kind of cracking resistance formula underground pipe gallery
Structure.
Background technique
Underground pipe gallery structural concrete is in underground structure, and design and construction must fully consider waterproof problem, but
The problem of seepage problem caused by it cracks has been a generality in the field, exactly, it should be one and extremely be difficult to
It solves the problems, such as and overcomes.
To find out its cause, mainly as caused by aquation temperature rise and the maintenance in later period of concrete etc., because of such coagulation
The label of soil is generally concentrated at C30~C40, and based on label C35, autogenous volumetric deformation is smaller, not in different construction environments
In the case where structure size design, aquation temperature rise is differed at 15~35 DEG C；Especially sidewall structure concrete is thin-walled
Structure, temperature rise rate is very fast, and temperature drop rate is also very fast, larger, the bottom plate knot poured in advance of concrete temperature drop contraction
The effect of constraint value of structure, easily generation crack or even more serious situation, fracture interval reach 0.8~1.5m/ item, 2~3m/
The crack of item is also relatively common, and there are a large amount of crosscutting concerns, and serious structure is caused to seep water.Since this crack causes
Later period patch work it is comparatively laborious, and the durability that patching material is not long-term, with the extension of structure active time, even
It needs next year to repair, Nian Nianxiu, structure safety and economic attrition problem are than more prominent.It is separately poured in top board structure and sidewall structure
In the case where, it is also same reason, the top board structure coagulation local products that the sidewall structure concrete poured in advance pours the later period
Raw strong constraint, leads to the generation of top board structure distress in concrete.
Therefore, in order to solve the problem of Cracking of underground pipe gallery structural concrete, it is necessary to establish a kind of new construction
Method eliminates constraint of the earlier casting concrete to later period casting concrete, thus the generation of effectively control critical eigenvalue.
