Description

Reinforced mould for wall hole mouth of stressed concrete structure

Technical Field

The utility model relates to the field of building construction, in particular to a reinforced mould for a through-wall hole of a stressed concrete structure.

Background

In urban rain and sewage diversion road lifting and transformation engineering, the original underground structure (barrier) is more and geological data are seriously lost, the original structure is extremely seriously damaged in the construction process, and meanwhile, a design pipeline cannot be constructed according to a design route and a burial depth. The traditional construction method needs to carry out line changing or structure crossing construction, and has extremely high requirements on the positions of surrounding underground structures and the strength of the structures. After the structural object wall body breaks the hole, the integral strength of the structure is reduced, and the structure is possibly cracked under the action of load such as a later-stage vehicle and the like, so that the road surface is unevenly settled. The serious collapse of the structure and the increase of the later repair cost, the formed repair 'patch' seriously affects the beautiful appearance of the road.

The internal force of the side wall around the cut hole is increased, the stress is concentrated, the reinforcement is reduced, and the bearing capacity is reduced. The traditional method for reinforcing the hole generally adopts a method of pouring high-grade concrete after reinforcing and encrypting steel bars are implanted, and has extremely high requirements on the strength and earthquake resistance of the reinforcing and encrypting steel bars and post-pouring concrete.
