Description of the Related Art Since fine particles of rocks, dust particles, and their slimes are attached to the wall surface of a tunnel excavated by a tunnel excavator, the wall surface is lined with concrete or sprayed. When applied, the adhesive force between the concrete and the wall surface is hindered by the particles and slime. Therefore, conventionally, the excavation wall surface is cleaned to remove the powder particles and slime before the concrete is sprayed or placed.

するものである。However, in the conventional cleaning work, the granular material and slime are washed off by manually operating the water hose and spraying pressure water from the hose onto the excavated wall surface. Therefore, not only a great deal of labor is required, but also it takes a lot of time to remove the treated water collected in the tunnel invert portion after water sprinkling, and there is a problem that the lining work and the like after that cannot be performed smoothly. The present invention is intended to solve such a problem, and provides a tunnel wall surface cleaning device that can continuously and automatically and efficiently clean a wall surface excavated by a tunnel excavator.

It is configured to move according to the excavation. A treated water collection cover is suspended from the movable base mounted on the beam member so as to be movable up and down, and the tip end of an arm projecting from both side surfaces of the movable base is foldable and the upper surface of the treated water collection cover. A flexible perforated pipe curved in an arc shape is rotatably attached between both side parts, and brushes are radially provided on the outer peripheral surface of the flexible perforated pipe over the entire length. Therefore, if the treated water collecting cover is hung down to the bottom surface of the excavation wall surface and the arm is projected toward both side surfaces of the excavation wall surface, the flexible perforated pipe is parallel to the curved surface of the excavation wall surface, The brush protruding from the pipe makes sliding contact with the excavated wall surface. In this state, when the rotary drive mechanism of the pipe attached to the tip of the arm is operated, the fine particles of rocks, dust, slime, etc. adhering to the excavated wall surface are scraped off by the brush.

Rinse off and retain the treated water on the bottom of the excavated wall. The bottom edge of the treated water collection cover faces the bottom surface and the tip of the suction hose is opened in this cover, so the treated water that has flowed into the cover is sucked by the hose and removed behind the tunnel. .

As the rock excavator digs into the rock ground for a certain length, the beam member 1 integrally moves forward to move to the rear of the tunnel excavator. Move to the excavated wall surface B. When reaching the excavated wall surface B, the winch 5d of the collecting cover elevating means 5 is operated to hang down the wire 5c to lower the collecting cover 4 and extend the rod of the arm rotating jack 21 to extend both side arms 9,
9 is rotated toward the excavation wall surface B side using the pivotal portion 10 as a fulcrum.
By rotating these both-sided arms 9 and 9 to the side of the excavation wall surface B and lowering the collection cover 4, the flexible perforated pipe 13 mounted between the tip of the arm 9 and the collection cover 4 becomes a part of the excavation wall surface B. Curved to a shape along the curved surface and approached the excavation wall surface B,
The brush 15 is brought into sliding contact with the excavated wall surface B.

When high-pressure water is supplied to the flexible perforated pipe 13 through 16,
At the same time as the brush 15 scrapes off fine particles of rocks, dust, slime, etc. adhering to the excavated wall surface B, high-pressure water is jetted from the large number of small holes 14 formed in the flexible perforated pipe 13. Then, it collides with the excavated wall surface B to wash away fine particles of rock and slime. The treated water containing fine particles of rocks and slime flowing down from the excavated wall surface B stays on the bottom surface of the excavated wall surface B.

Through the tunnel, it is discharged to the proper place behind the tunnel and processed.
The treated water outside the collecting cover 4 flows into the collecting cover 4 in accordance with the suction amount of the suction hoses 8 and 8a, and the moving pedestal 2 is moved in the front-back direction by driving the motor 18 through the wire 20 to collect the cover. 4 and the position of the flexible perforated pipe 13 projecting the brush 15 are changed,
Is cleaned in the longitudinal direction, and the treated water accumulated on the bottom surface of the excavated wall surface B is sucked and removed by the suction hoses 8 and 8a.

引出し長さを設定することができる。The flexible perforated pipe 13 rotated by the rotary drive mechanism 11 is subjected to tensile force on the convex arcuate peripheral surface side facing the excavation wall surface B side, and the concave arcuate peripheral surface facing the tunnel center side. Since a compressive force acts on the side, the flexible perforated pipe
The small hole 14 for ejecting pressured water, which is bored in 13, expands greatly on the convex arcuate peripheral surface side, but is compressed in the direction of closing on the concave arcuate peripheral surface side, and the compressed water is directed toward the excavation wall surface B. Can be sprayed intensively. Further, if the hose winding drum 6 is constantly urged in the winding direction, it is possible to set the withdrawal length of the hose 8 from the hose winding drum 6 in accordance with the front-back movement of the movable mount 2.

Meanwhile, the excavated wall surface B is washed, and the treated water is sucked and removed through the suction hoses 8 and 8a facing the collection cover 4. When the cleaning work of the excavation wall surface B is completed, the winch 5d of the elevating means 5 is actuated in the rewinding direction to lift the collecting cover 4 so that it is separated from the bottom surface of the excavation wall surface B and the rod of the arm rotating jack 21 is contracted. As a result, the both arms 9, 9 are folded in the direction along the beam member 1 as shown in FIGS. 3 and 4 to prepare for the next cleaning operation.

ことができる。As described above, according to the tunnel wall surface cleaning apparatus of the present invention, the treated water collecting cover is vertically movably suspended on the movable base mounted on the beam member movable in the tunnel length direction. A flexible perforated pipe curved in an arc shape is rotatably attached between the distal end of the arm projecting from both side surfaces of the movable base so as to be foldable in the front-rear direction and both side portions of the upper surface of the treated water collection cover. Since the brushes are radially projected on the outer peripheral surface of the flexible perforated pipe over the entire length, the treated water collection cover is hung down to the bottom of the excavation wall and the arms are directed toward both sides of the excavation wall. By protruding the flexible perforated pipe in parallel with the curved surface of the excavated wall surface, a brush protruding from the pipe is slidably contacted with the excavated wall surface to form a flexible perforated pipe. Dig by rotation Fine particles and slime rock adhering to the wall surface can be dropped successively automatically scraped the tunnel length.

Fine particles and slime of rocks present and fine particles and dust of rocks scraped off by the above-mentioned brush can be washed off, dust and the like can be prevented from floating in the tunnel, and a good working environment can be maintained.

Since it is opened, the treated water flowing into the collection cover can be surely sucked and removed by the suction hose, and the excavation wall surface can be cleaned efficiently. In addition, the raising / lowering position of the collecting cover can be freely set according to the diameter and deformation of the excavated wall surface, and the flexible perforated pipe can be curved along the excavated wall surface. When the cleaning work is completed, the treated water collection cover is lifted to separate it from the bottom of the wall surface for excavation, and both arms are folded in the direction along the suspension beam to widen the work space in the tunnel and facilitate other work. It has practical effects such as being able to be performed.
