Abstract

The invention discloses an underground support pile glass fiber rib-steel reinforcement cage and a connecting method thereof. The technical problem that in the prior art, glass fiber ribs cannot be stably connected, and the glass fiber ribs and steel reinforcements cannot be stably connected is solved. The glass fiber rib-reinforcement cage comprises a glass fiber rib cage and a reinforcement cage, wherein the glass fiber rib cage comprises glass fiber rib main ribs, annular glass fiber rib reinforcing ribs and spiral glass fiber rib stirrups; the steel bar main reinforcements and the glass fiber reinforced plastic main reinforcements are connected through buckle mechanisms. The connecting method mainly comprises the steps that the glass fiber rib main ribs and the steel bar main ribs are connected through the buckle mechanisms, and the glass fiber rib main ribs are fixedly bound with the annular glass fiber rib reinforcing ribs, the spiral glass fiber rib stirrups and the horizontal glass fiber rib reinforcing ribs through 10 # iron wires respectively. The steel bar main reinforcements and the glass fiber reinforced plastic main reinforcements are connected through the buckle mechanisms, the whole structure is stable and firm, and the requirement for smooth crossing of a shield in the later period can be met.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to a glass fiber reinforcement-reinforced cage of an underground supporting pile and a connection method thereof. Background technique [0002] Fiberglass bars have high tensile strength and low shear strength. The biggest difference between glass fiber reinforcement and steel reinforcement is that the elastic modulus of glass fiber reinforcement is small, which is a typical brittle material. The stress-strain curve shows an obvious linear relationship before fracture, which greatly affects the lifting of glass fiber reinforcement cage. Stability and flexural and shear bearing capacity of fiberglass reinforced diaphragm walls during foundation pit excavation. Fiberglass bars have high bearing capacity and strong tensile capacity. The strength of the rod body is twice that of threaded steel bars of the same diameter, but the quality is only 1 / 4 of the steel...
