However, in the case of concrete structures such as tunnels and bridge roofs, the concrete structures are located at a relatively high position from the ground, unlike the above-mentioned rock or general buildings. In the past, Etc., as well as a variety of equipments including an anti-crushing machine for crushing to a position to be repaired, as well as a repair work including a partial crushing operation is carried out by placing the worker directly on the bottom of the concrete structure.

Therefore, when performing the method of repairing the bottom surfaces of various concrete structures such as tunnels, bridges and the like including the culvert in the past, a lot of equipment is required, and in addition, There is a problem that the cost is increased.

In addition, it is not possible to secure the safety of the operator during the work of repairing the bottom of various concrete structures. Especially, it is possible to prevent the concrete from being damaged due to various wastes including concrete fragments and aggregates generated when crushing a part of the concrete to be repaired at the bottom of the concrete structure There is a concern that safety accidents such as a worker may be injured, and there is a problem that scattering of dust or the like is prevented from being prevented or collected, and thus environmental pollution occurs.

Therefore, when the crusher 30 is installed on the rail 20, the anti-scattering rubber plates 38 provided on the upper end of the drum case 31 are resiliently attached to the bottom surface of the concrete structure 10 Various wastes including dust generated when the bottom surface of the concrete structure 10 is crushed through the scraper drum 32 are blocked by the blocking function of the scattering prevention rubber plates 38, It is possible to prevent safety accidents and environmental pollution caused by dusts that may be generated by scattered wastes (e.g., concrete pieces, etc.).

In the present invention, a waste and dust discharge pipe 39 is detachably installed in the waste discharge hole 312 formed in the hopper 311 of the drum case 31, and if necessary, A flexible tube 391 for connecting to a movable carriage 50 provided with a wheel so as to be able to move on the ground at the bottom end of the movable carriage 39 is further provided.

Accordingly, in order to repair the bottom surface of the concrete structure, the crusher 30 to which the present invention is applied is joined to the rail 20 fixed to the bottom of the concrete structure, and various kinds of aggregates including concrete fragments It is possible to automatically collect the waste and dust in the ground-type movable carriage 50 through the waste and dust discharge pipe 39 and the flexible pipe 391 so that the safety of the operator can be largely ensured or secured, It is possible to prevent the environmental pollution caused by the scattering of the dust, and the working environment can be greatly improved.

In addition, in the present invention, dust collecting dust collector 60 having a filter 61 is installed in the movable truck 50 as shown in FIGS. 4 and 5, It is possible to prevent damage to the surrounding environment due to dust and worker's damage in advance. Especially, it is possible to maintain a pleasant working environment, and thus reliability according to repair of the bottom of a concrete structure can be greatly improved.

The crushing method for repairing the bottom of a concrete structure using the apparatus of the present invention will be described with reference to FIG.

First, a pair of rails 20 are detachably fixed to a concrete structure 10 such as a tunnel and a bridge, including a culvert, by using a plurality of fixing means 21, S1).

Next, a crusher 30 having the above-described configuration is detachably installed (S2) between one end of the pair of rails 20 as shown in Fig. 2, and then the drum case 31 of the crusher 30 A waste and dust discharge pipe 39 integrally or detachably provided in the hopper section 311 formed at the bottom or a movable car with a flexible pipe 391 provided on the ground at the bottom of the waste and dust discharge pipe 39 50 as shown in FIG. 4 (S3).

Thereafter, the operator operates the drum and motor ascending / descending means 37 provided in the crusher 30 through the operating portion provided in the controller 40 to rotate the scraper 30 and the drum 32, The outer surface of the screw drum 32 is elastically brought into close contact with the bottom surface of the concrete structure 10 by moving the driving motor 34 up and down (S4).

Next, the drum driving motor 34 provided in the crusher 30 is driven through the operating unit of the controller 40 so that the flattening drum 32 starts to crush the bottom surface of the concrete structure 10 as shown in FIG. 3 (S5).

At this time, if the dust collector 60 provided with the filter 61 is further installed on the movable truck 50, the operator drives the dust collector 60 to perform the process S6 .

When the dust collecting dust collector 60 provided with the filter 61 is further driven in this manner, the operator drives the drum driving motor 34 through the operating portion of the controller 40 Various wastes including dust generated when the bottom surface of the concrete structure 10 in a predetermined section is broken through the planer drum 32 are discharged through the waste and dust discharge pipe 39 and the flexible pipe 391 50, most of the dust is caught by the filter 61 of the dust collecting dust collector 60, so that the dust contained in the waste can be completely prevented from scattering into the air.

When the operator completes the above-described process, the operator moves the forward and backward driving means 36 forward (S7) through the operating portion of the controller 40, The crusher 30 which is crushing the bottom surface advances along the rail 20 by a predetermined speed at a predetermined speed corresponding to the driving of the forward and backward driving means 36 and continues crushing.

As a result of the crushing operation by driving the planarizing drum 32 and the advancing process of the crushing machine by driving the forward and backward driving means 36 as described above, When the crushing is completed, the operator stops the driving of the forward and backward driving means 36 through the operating portion of the controller 40 to stop advancing the crusher 30 on the rail 20, The driving of the flat drum 32 is stopped and the drum and motor elevating and lowering means 37 are lowered to stop the driving of the flat drum 32 at a predetermined distance from the bottom surface of the concrete structure 10 (S8).

In the state where the crusher 30 according to the present invention is coupled to the rail 20 and then moved forward along the rail and the crushing operation of the concrete structure for the predetermined section is completed, the operator places the crusher 30 on the rail (S9) for separating the liquid crystal molecules from each other.

At this time, as a method of separating the crusher 30 from the rail 20, an appropriate method may be selected according to the situation of the site. For example, the crusher 30 advanced to the other end of the rail 20 may be directly separated from the rail 20 at that position, and the forward and backward driving means 36 The crusher 30 is moved backward to one end of the rail 20 (that is, the first installation and start position), and then the crusher 30 is separated through the one end of the rail 20.

After separating the crusher 30 from the rail 20 as described above, when the rails 20 installed in the corresponding section are separated from the bottom surface of the concrete structure 10 (S10) The shredding operation is completed.

As described above, according to the present invention, when a part of the bottom of the concrete structure is to be repaired, the rails are fixedly installed on the bottom of the concrete structure in the maintenance section, and the crusher applied to the present invention is simply coupled to the rail, It is possible to secure the safety of the work due to the crushing of the bottom of the concrete structure, as well as to greatly reduce the time and cost of the partial crushing.

Although the preferred embodiments of the present invention have been described for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims. Which will be apparent to those skilled in the art.
