Problems solved by technology

[0003] During the construction of the tunnel under the existing bridge, it will undoubtedly cause deformation and displacement of the surrounding rock in a certain range. When the stress and deformation of the surrounding rock are transmitted to the bridge, it will break the original balance of the soil around the pile foundation. The stress state will reduce the bearing capacity and self-stabilization capacity of the pile foundation and the superstructure, directly affect the normal use of the existing bridges or door openings in operation, and even lead to the instability and damage of the pile foundation structure and the above structures

Abstract

The invention discloses a method for reinforcing a municipal highway door opening, which comprises the following steps: 1) measuring and setting out the door opening, 2) installing a slotting device, 3) slotting the inner wall of the door opening, 4) installing a reinforcing mechanism, 5) constructing a reinforced concrete column and 6) Door opening detection. The invention is not only convenient and fast in construction, but also realizes secondary reinforcement through the reinforcement mechanism and reinforced concrete columns, greatly improving the stability and reliability of road door opening reinforcement, high construction precision, and greatly improving the safety of road door openings.

Description

technical field [0001] The invention relates to a reinforcement method for a municipal highway doorway. Background technique [0002] In recent years, my country's railway and highway construction has developed rapidly. Whether it is a railway or a highway, the proportion of bridges and tunnels is very high. In the process of line selection, railway and highway tunnels will inevitably meet the situation of close intersection with existing operating highways and railways. [0003] During the construction of the tunnel under the existing bridge, it will undoubtedly cause deformation and displacement of the surrounding rock in a certain range. When the stress and deformation of the surrounding rock are transmitted to the bridge, it will break the original balance of the soil around the pile foundation. The stress state will reduce the bearing capacity and self-stabilization capacity of the pile foundation and the superstructure, directly affect the normal use of the existing b...
