Description

  The present invention relates to a method for moving an excavator on a frame, and more specifically, moves the excavator to provide a drilling hole for placing an anchor or a lock bolt in a natural ground at the frame frame intersection. Regarding technology.

  As a construction method for preventing slope collapse, surface layer protection, and slope greening, there is known a frame construction method in which a grid frame is constructed on the slope using cast-in-place concrete, sprayed mortar or sprayed concrete. In such a method frame construction method, as a measure for further stabilizing the slope and preventing a slope from slipping, an anchor method or a rock bolt method is used in combination.

  In order to carry out this anchor work or rock bolt work, a drilling machine is drilled in the natural ground at the legal frame intersection. Since drilling is an operation on a slope, conventionally, a method has been adopted in which a scaffold is built on the slope and an excavator is installed on the scaffold. However, since the method of assembling such a scaffold requires time and labor for its assembly, disassembly, etc., a method of moving the excavator to the drilling position on the frame is also proposed (see Patent Document 1). ).

Specifically, this moving method is a method in which a guide rail is installed using a frame and the excavator is moved up and down using the guide rail as a guide. However, in the case of embankment and cut slope, the slope is flat, so the top of the slope is almost the same, but in the case of natural slope, the slope is uneven and the top of the slope is almost the same. It will not be the same flat surface. For this reason, when the excavator is caused to travel along the guide rail, the guide rail may be flexibly deformed. If such a deformation occurs, it may be difficult to move the excavator.

The present invention has been made based on the technical background as described above, and achieves the following object.
The object of the present invention is to make it possible to smoothly move the excavator even on a slope with irregularities, and to use a simple facility, which can be easily installed and removed. It is to provide a method of moving an excavator in the country.

The present invention employs the following means in order to achieve the above object.
That is, according to the present invention, a grid-like pipe is laid on the surface of the frame, and an excavator is mounted on the warp-like frame, and the warp-like frame is slid vertically on the grid-like pipe by driving a winch. The excavator is moved to a required drilling position by moving the excavator on the normal frame.

  More specifically, the grid-like pipe is fixed to the legal frame by a fixing rope attached in advance to a frame portion in the vicinity of the legal frame intersection at the time of construction of the legal frame. Further, in order to obtain a reaction force at the time of drilling by the excavator, the sled frame is fixed to the normal frame using the fixing rope.

  According to the present invention, a grid-like pipe is laid on the upper surface of the frame, and the excavator is moved by sliding the sled frame on which the excavator is mounted on the grid-like pipe. It is possible to realize a moving method with a high degree of freedom without different constraints. Therefore, even if the slope is uneven and the upper surface of the frame is not the same flat surface, even if the lattice pipe is bent and deformed, there will be no hindrance to movement and the excavator will move smoothly. Can be made. Moreover, since the main equipment to be used is a grid-like pipe, it is simple and can be easily installed and removed.

  Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 show an embodiment of the present invention, and are a plan view and a cross-sectional view, respectively. The frame 1 is a lattice-shaped frame composed of a number of vertical frames 1a and horizontal frames 1b, and a mold is placed on the slope and mortar or concrete is sprayed (spraying method) or concrete is cast. (On-site construction method). During the construction of the frame, the holes 2 are formed using voids or the like at the intersections of the vertical frame 1a and the horizontal frame 1b.

  The excavator 11 is moved in the vertical direction on the normal frame 1 and a drill rod is inserted through the hole 2 at the normal frame intersection, and an anchor hole and a lock bolt hole are drilled in the natural ground. According to this invention, in order to move the excavator 11 on the frame 1, the lattice pipe 3 is laid on the surface of the frame 1. The grid-like pipe 3 is made by fixing a number of vertical pipes 3a and horizontal pipes 3b made of a single pipe in a grid pattern. The size of the grid-like pipe 3 does not have to be a size that covers the entire frame, and may be a size that covers an appropriate number of columns of the vertical frames 1a. This is because the vertical movement of the excavator 11 is repeated to complete the drilling of each normal frame intersection of the portion covered with the grid-shaped pipe 3, and the grid-shaped pipe 3 may be moved in the lateral direction.

  As shown in FIG. 3, a fixing rope 4 is attached in advance to the vertical frame 1 a in the vicinity of the normal frame intersection at the time of construction of the normal frame 1. In the illustrated example, the fixing rope 4 is embedded through the vertical frame 1a, but may be laid under the vertical frame 1a. The grid-like pipe 3 is fixed to the frame 1 using the fixing rope 4.

  The excavator 11 is mounted on a warp-like frame 5 as shown in FIG. 4 and moved by sliding the warp-like frame 5 on the grid-like pipe 3. The sled frame 5 can take various forms. In this embodiment, the sled frame 5 includes a pair of sled legs 6 and a connecting bar 7 that connects the sled legs 6. The excavator 11 is placed on the connecting bar 7 and fixed.

  As a driving means for moving the excavator 11, a winch 8 installed in the lower part of the slope is shown in FIG. The rope 9 drawn out from the winch 8 toward the upper part of the slope is inverted via a support 10 such as an anchor installed at the upper part of the slope and extends toward the lower part of the slope, and is fixed to the excavator 11. The rope 9 may be fixed to the sled frame 5 instead of the excavator 11. Further, the winch 8 may be mounted not on the lower part of the slope but on the upper part of the slope or the sled frame 5.

  The excavator 11 is moved up and down for each vertical frame 1a. Specifically, the drill head 11a is moved so that the axis of the drill head 11a is on a line connecting the intersection (hole 2) of the vertical frame 1a. Drilling may be performed as the excavator 11 is raised, or may be performed as the excavator 11 is lowered. When the excavator 11 moves to the position of the hole 2 to be drilled, the excavator 11 is fixed to the frame 1 in order to take the excavation reaction force. In order to fix the excavator 11, the fixing rope 4 near the excavator 11 is temporarily removed, and the warped frame 5 is fixed to the frame 1 using the fixing rope 4. Then, a drill rod (not shown) attached to the drill head 11a is passed through the hole 2 to drill a natural ground. The fixing rope 4 is cut and removed after construction.

  As described above, when the drilling at one leg frame intersection is completed, the excavator 11 is moved to the intersection above or below the intersection to drill a natural ground. Then, when all the drilling of the intersection part for one vertical frame 1a is completed, the excavator 11 is moved in the horizontal direction together with the sled frame 5 to the adjacent vertical frame 1a, and the cutting of the intersection part for the vertical frame 1a is performed. Make a hole. The excavator 11 is moved in the lateral direction using a crane or the like.

  As described above, the excavator moving method according to the present invention is such that the grid-like pipe 3 is laid on the upper surface of the frame 1 and the sled-like frame 5 on which the excavator 11 is mounted is slid on the grid-like pipe, This is a method for moving the excavator 11, and is a movement method with a high degree of freedom without restriction as in the conventional rail system. Therefore, even if the slope is uneven and the upper surface of the frame 1 does not become the same flat surface, and as a result, even if the lattice-like pipe 3 is bent and deformed, the movement is not hindered and the excavator smoothly Can be moved.

  Further, a fixing rope 4 is attached to the frame 1 in advance, and the grid pipe 3 is fixed to the frame 1 by using the fixing rope 4 or the excavator 11 is used to take a digging reaction force. Since it fixes to the frame 1, installation of the temporary anchor etc. for fixing becomes unnecessary.

It is a top view which shows embodiment of this invention. It is sectional drawing of the same embodiment. It is a perspective view which shows a rope for fixing. It is a perspective view which shows a sled frame.
