Description

[0001] Slope perforation system and method [0002]

The present invention relates to a mobile drilling machine for reinforcing a slope on a road construction site, and a slope drilling system and method using the same, wherein the mobile drilling machine performs a drilling operation while moving the slope face from side to side, .

A sloping sloping surface is necessarily formed on one side or both sides of a road which is opened to pass through a mountain waist, a mountain valley or the like. Such slope collapse, rockfall, and earth leakage are major threats to the safety of a vehicle that travels on the road, so it is essential to reinforce or stabilize the slope. If slope inclination is gentle, slope protection block is installed. In case slope of slope slope is urgent, rock bolt, anchor, nail, etc. are put on and then mesh is installed on slope surface to prevent slope slope, falling stone, .

When a rock bolt, anchor, nail, or the like is provided on the slope surface, an operation of forming a perforation hole is involved. Equipment for forming perforation holes on the slope surface is a miniature shear and crawler drill. However, it is necessary to form the drilled hole with a depth of about 1 m and a depth of about 1 meter, and the rock bolt or the like, which is pushed to a depth of about 1 meter, can not firmly reinforce the sloped surface. A crawler drill can climb itself on a gentle slope to pierce a hole, but it is not possible to climb on its own when the slope is steep. In order to solve these disadvantages, there are cases where a scaffold is installed so that the crawler drill can climb the steep slope, but there are problems that the scaffolding itself is difficult and the risk is followed, and a lot of equipment, manpower and time have.

Below is a photograph of a case where a crane and a perforator are working together. However, it takes a lot of work and work yard for large crane setting, and there is a risk of overturning when the crane installation surface is poorly collapsed. In addition, it is not possible to perform parallel operation with the lower section earthwork work, so that the entire slope construction work air is delayed and can not be applied to a site where the crane is difficult to enter.

Since the slope is uneven, three wheels are more stable than four wheels. Therefore, the front wheels 12a may be provided on both the front left and right sides of the vehicle 10, and the rear wheels 12b may be provided on the rear center of the vehicle 10. [

As shown in FIG. 1 (c), the traveling direction is adjusted in such a manner that the rear wheel 12b is pushed in a diagonal direction on both left and right sides of the rear wheel 12a provided at the rear center of the vehicle 10 And a steering device 18 may be further included. The steering device 18 is a piston type in which the piston advances and retreats by hydraulic pressure or pneumatic pressure so that when one of the steering devices 18 pushes the rear wheel 12b, the other steering device 18 rotates the rear wheel 12b So that the traveling direction of the mobile perforation equipment 10 can be adjusted. When the traveling path of the mobile perforating equipment 10 and the perforation hole forming positions on the slope surface do not exactly coincide with each other, the left and right movements are performed by a predetermined distance by the operation of the steering device 18, Can be exactly aligned with the plane.

The perforator 13 is configured such that the perforation bit 13-1 is advanced and retreated forward and backward as needed, and is horizontally coupled to the upper portion of the truck 11.

The first wire rope 25a is wound on a first winch 20a which will be described later. One end of the first wire rope 25a is coupled to the first winch 20a and the other end thereof is connected to both ends of the first winch 20a. And are fastened to the combined running hoop rings 15, respectively. The second wire rope 25a is wound on a second winch 20b to be described laterally and one end portion thereof is coupled to the second winch 20b and the other end portion is connected to both ends of the second winch 20b, And is fastened to the work lifting hook 17 on the upper part of the coupled rear support 16, respectively.

The first and second winches 20a and 20b simultaneously wind or unwind the first and second wire ropes 25a and 25b when the mobile perforation apparatus 10 is raised or lowered along the slope the second wire rope 25b is driven by the mobile perforation equipment (not shown), and the second wire rope 25b is driven by the second wire rope 25b when the mobile perforation equipment 10 intends to perforate the work surface, 10) to raise the rear (see Fig. 2 (b)).

The outrigger 14 is coupled to the bogie 11 in a forward direction and is configured to move forward and backward as necessary. The outrigger 14 can be formed in a cylinder shape configured to advance and retreat the piston by hydraulic pressure, pneumatic pressure, or the like. The outrigger 14 is retreated so as not to interfere with the traveling of the mobile perforation equipment 10 when the sloping surface of the mobile perforation equipment 10 travels (refer to FIG. 2 (a) The outrigger 14 is advanced and grounded on the slope surface, whereby the stability of the working state can be imparted.

The step (e) may be followed by repeating the steps (b) to (e) to form a perforation hole at a predetermined interval along the longitudinal direction of the slope surface. That is, according to the step (f), ① the mobile perforation equipment 10 is pulled up and the rear side is lifted to prepare for the operation (step (b)) → ② the stabilization of the arrangement state of the mobile perforation equipment 10, (step (c)). (3) A plurality of perforation holes may be formed at predetermined intervals from the bottom to the bottom of the mobile perforation equipment 10 by repeating the process of preparing the mobile perforation equipment 10 to travel downward (step (d)).

After the step (f), the first and second wire ropes 25a and 25b are simultaneously released from the first and second winches 20a and 20b, and the front wheel 12 and the rear wheel 13) may be rolled down along the slope so that the movable perforation equipment 10 is positioned below the slope surface (g). When the movable perforation equipment 10 is moved upward in a state of being pulled up to the upper part of the slope surface, stability of the operation is low. Therefore, the moving and perforating equipment 10 is lowered down the slope surface through step (g).

 After the step (g), the first and second wire ropes 25a and 25b are cut from the first and second winches 20a and 20b while the chain 55 is loosened by a predetermined length from the chain block 50 (H) of winding the moving pulley 60 to the fixed pulley 40 in the lateral direction. When the chain 55 is loosened from the chain block 50, the first and second wire ropes 25a and 25b are loosened by the length of the loosened portion. When the first and second wire ropes 25a and 25b loosened at the first and second winches 20a and 20b are simultaneously wound, the first and second wire ropes 25a and 25b are tightened, ) Moves to the inside (the side on which the fixed pulley is installed). The distance that the moving pulley 60 is moved in the lateral direction is the perforation hole transverse spacing.

After the step (h), the mobile perforation equipment 10 is repeatedly moved to the fixed pulley 40 at a predetermined interval along the longitudinal direction of the slope in a state of approaching a predetermined distance by repeating the steps (b) (I) for forming a hole can be carried out.

The step (i) may be followed by the step (j) of repeating the steps (g) to (i). Accordingly, the movable perforating equipment 10 is moved from the lower part of the slope to the upper part, and the drilling operation is performed. Then, the movable perforating equipment 10 is moved in the lateral direction to move from the lower part to the upper part, The perforation holes can be formed at predetermined intervals.

The present invention has been described in detail with reference to the accompanying drawings. However, it should be understood that the present invention is not limited to the above-described embodiment, and various modifications and changes may be made without departing from the technical spirit of the present invention. It is therefore intended that the appended claims cover such modifications and variations as fall within the true scope of the invention.
