Description
One, technical field
The invention relates to double steel plate local restriction concrete walling, is particularly useful for the deep shaft in the deep thick alluvium of mine construction and Fu Shui rock stratum, as normal sinking, freezing process, boring method and drop shaft sinking sinking shaft pit shaft.
Two, background technology
Along with the exploitation of China's deep mineral resources, pit shaft is built the degree of depth and is constantly increased, and shaft lining load-bearing power has to significantly increase, to bear increasing deep rock thrust and hydraulic pressure.For this reason, only have two kinds by way of: one is that shaft wall structure is constant, improves the strength of materials and thickness; Two is change shaft wall structure.Steel concrete wall construction conventional has at present been difficult to the needs adapting to Deep Mine construction, and cast iron usual abroad or the cast steel borehole wall, mound guest's block borehole wall, the concrete arc plate borehole wall need, down-hole assembling prefabricated on ground, its construction technology is complicated, difficulty is large, cost is high, difficult quality guarantee.
Prior art, by arranging the closed skeleton of annular in borehole wall inside, improves the total bearing capacity of the borehole wall.The metallic framework of this borehole wall, can not make borehole wall inner surface concrete become triaxial stress state from plane stress, can not give full play to concrete triaxial shear strength.
Prior art, by arranging double-layer plate on the inside and outside surface of the borehole wall, radial connector builds formation concrete walling.This type borehole wall utilizes double-layer plate to implement overall radial constraint to the borehole wall, and on the one hand, steel plate consumption is large, and inside the borehole wall, concrete intensity improves not remarkable; On the other hand, outside the borehole wall, concrete intensity improves, little to the contribution of borehole wall horizontal bearing capacity.In fact, inner side concrete is the core space of shaft lining load-bearing, and existing double-layer plate concrete walling fails the strength of materials that improves targetedly inside the borehole wall, and economy is relatively poor.
