Description

[0001] REPAIRING APPARATUS FOR CONCRETE JOINT [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a joint repairing apparatus, and more particularly, to a joint repairing apparatus that can automatically and continuously carry out a work of removing foreign matter from a joint portion of a road and filling a filler.

Generally, concrete pavement slab in road pavement repeats expansion and contraction due to difference in temperature and humidity. Therefore, in order to reduce the stress generated thereby and to prevent the occurrence of cracks, Additional construction is done. There are CONCRETE JOINT and abutment part at the junction of the road.

The joint portion can be roughly classified into two types, i.e., a transverse portion provided in the lateral direction of the package (width direction of the road) and a longitudinal portion provided in the longitudinal direction of the package (longitudinal direction of the road).

Such a joint increases the degree of damage of the slab when the slab is expanded in the state where the incompressible material is inserted, which not only causes local damage to the joint but also damages the inside of the package slab adjacent to the joint.

Therefore, it is necessary to carry out the repair work quickly by removing the damaged part and constructing a new package at the joint when damage is caused to the joint of the road pavement.

In addition, when the joints are filled with foreign matter, weeds, soil, etc., the joints fail to function, and this also requires a maintenance work to remove the foreign matter, weeds, soil and the like in the joints and fill the filler rapidly .

However, in the conventional joint repair operation, the worker must manually remove the foreign matter deposited on the joint using a tool, which requires a long maintenance work on the joint.

Therefore, there is a need to improve this.
