* Overview

It is a technology that elevates bridge structure to replace aging bridge bridge bridge bridge system, and uses flow-controlled multi-pump and computer-centered control method to reduce bridge inequality.

To raise simultaneously, prevent fall and conductance accidents through safety jacks, and to one side by mounting an account.

A technique for preventing eccentric moment where force can be increased.


* Scope of construction methods

Using the flow-controlled multi-pump and computer-centered control method, the construction method for controlling the rise of large structures, the technology for preventing fall and conduction accidents using safety jacks, and the use of a detention system.

eccentric moment prevention technique

* Principle of public law

1) Flow control method that can simultaneously and simultaneously raise hydraulic jacks

- Impressive displacement of the hydraulic jack regardless of the size of the load applied at the point

A technique that automatically controls up to the impression target by setting it.

- Precision construction with an impression precision of 0.5mm can be done.​

2) Falling bridge and anti-conducting safety jack (MAS jack)

- Raising the safety jack equipped with reverse anti-progressive interlocking simultaneously with the hydraulic jack may occur in case of abnormal behavior of the hydraulic jack.

- After raising the target height, the position of the safety jack is automatically fixed to remove pressure from the hydraulic jack.

- The safety jack supports the load of the upper plate even if the hydraulic jack is accidentally lowered due to malfunction of the hydraulic jack consists of a cogwheel structure inside the safety jack.​

​

3) Hemispherical "deposit device" that eliminates the occurrence of eccentric moment

- The upper part of the hydraulic jack and the safety jack are installed with a hemispherical check system, respectively, the upper structure of the bridge and the lower part of the bridge.

To transfer the eccentric load of an uneven surface or upper structure of a bridge to the central axis.

- Conduction of bridges and fall accidents by preventing damage or dislocation of load support devices such as hydraulic jacks and safety jacks.

It shuts off and additionally provides a function to prevent loss of function of hydraulic and safety jacks.​

​

1) Overview of construction

On-site inspection and investigation -> Installation of vertical reinforcement (steel bridge) -> Installation of hydraulic jacks and MAS jacks -> Input of bridge impression DATA -> Increase of hydraulic jacks -> Repair and reinforcement of bridges -> Reduction of hydraulic jacks -> Dismantling of hydraulic jacks and MAS jacks​
