Steel reinforced cage applicable to air shaft underground continuous wall and using method thereof

Abstract

The invention provides a steel reinforced cage applicable to an air shaft underground continuous wall and a using method thereof. The steel reinforced cage comprises two layers of steel reinforced meshes; the two layers of steel reinforced meshes are connected to each other through truss ribs; the truss ribs comprise longitudinal truss ribs and horizontal truss ribs; main ribs are arranged in thelength direction of the steel reinforced cage; the longitudinal truss ribs are arranged parallel to the main ribs at intervals; one end of each longitudinal truss rib is connected to a hanging rib; the horizontal truss ribs are perpendicularly and fixedly connected to the longitudinal truss ribs; the longitudinal truss ribs intersect and are connected to the horizontal truss ribs; a shearing support is arranged on the horizontal truss ribs on the inner sides of the steel reinforced cage, and is used for fixing and moulding the longitudinal truss ribs and the horizontal truss ribs. According tothe steel reinforced cage, the sizes of components can be compatible; the phenomenon of twisting, deforming and shattering during conveying is avoided; hoisting and positioning are convenient; the size of each steel reinforced cage is uniform; the integral rigidity of the steel reinforced cage is large; and meanwhile, twisting and deforming can be well avoided during conveying and hoisting.

Description

technical field [0001] The invention belongs to the technical field of tunnel construction, and in particular relates to a reinforcement cage suitable for an underground diaphragm wall of an air shaft and a use method thereof. Background technique [0002] With the further development of cities in our country, urban subways are rapidly developing into the main means of transportation to relieve urban traffic pressure. Shield construction technology is currently the main construction method for subway tunnel construction. During the tunnel construction process, the interval air shafts of subway stations are mostly reinforced concrete cast-in-place structures, which are constructed by open-cut methods, and the enclosure structure is in the form of underground diaphragm walls+ Inner support mode. Due to the complex hydrogeological conditions where the wind shaft is located, multiple layers of soft soil are intermittently distributed, and the soft soil surrounding rock is of po...

Problems solved by technology

[0008] The purpose of the present invention is to overcome the problems in the above-mentioned prior art that the reinforcement cages are not made on the platform, and the size is not controlled by clamps for binding, and the spot welding is fixed, so that the sizes of each part are different, and the transportation is twisted and deformed, and it cannot be hoisted and installed in place. , and the improper lifting point, the technical defect of twisting and deformation due to insufficient rigidity during transportation and lifting
