Description

Technical Field

[0001] The utility model relates to the technical field of bridge construction, in particular to a prestressed concrete bridge body maintenance device. Background Art

[0002] Bridges are currently an important carrier of transportation. They are mainly built of concrete and are generally built on rivers, lakes, and seas to allow vehicles and pedestrians to pass smoothly. Prestressed concrete bridges use the reaction force of the pre-tensioning force of steel bars or steel wires (cables) to pre-compress the concrete before loading. This has the advantages of saving steel and reducing the material cost of bridges. At present, the bridge pavement is long-term eroded by rainwater, and the sulfate in the rainwater will cause the concrete protective layer on the pavement to be damaged. In the long run, it will seriously affect the durability of the bridge. Therefore, the bridge needs to be maintained regularly to ensure that the service life of the bridge is extended.

[0003] The current bridge maintenance equipment mainly includes bridge inspection vehicles, concrete jet pumps and high-pressure hydraulic breakers, etc. Among them, the high-pressure hydraulic breakers mainly use water as the working medium, and form a high-speed jet beam through a booster device and a nozzle of a specific shape to generate huge impact energy to break the cement concrete, thereby facilitating subsequent road repairs. Compared with existing drilling rigs, high-pressure hydraulic breakers produce less noise, and concrete is a non-homogeneous porous material, while steel is a homogeneous material. Therefore, when using a high-pressure hydraulic breaker to break concrete, the ejected water flow can only break the concrete without causing damage to the internal steel bars. Compared with the existing drilling rigs that will damage the steel bars if used improperly, the high-pressure hydraulic breaker can effectively protect the foundation structure of the prestressed bridge;

[0004] However, after the high-pressure water flow sprayed by the current high-pressure hydraulic breaker breaks the concrete, the existing equipment is unable to recycle the sprayed water, resulting in the water only flowing on the road surface, causing a lot of waste of water resources, which is not conducive to the protection of water resources. Based on this, the present application proposes a prestressed concrete bridge body maintenance equipment to solve the above problems. Utility Model Content

By using this scheme, the assembly between the spacer and the hemispherical cover can be achieved.
