[0002]

2. Description of the Related Art For example, in the construction of a slope on a slope, work such as drilling of an anchor hole is required. In this case, usually, a scaffold is assembled on a slope, and drilling is performed while a drilling machine is sequentially installed at a predetermined location.

[0003] However, construction of a scaffold requires a great deal of trouble, and it is sometimes difficult to secure the scaffold even on a steep slope.

In Japanese Patent Publication No. 7-33682, for example, a pair of left and right anchors are fixedly provided on the forehead, and a pair of right and left winches are fixedly provided on the construction device.
Alternatively, a pair of left and right winches are fixedly provided on the forehead, and a pair of left and right wire locking tools are fixedly provided on the construction device, and the wires of the left and right winches are respectively connected to the left and right anchors, etc. There has been proposed a technique of performing construction on a slope while raising and lowering a construction apparatus by winding or unwinding a wire (hereinafter, simply referred to as prior art).

[0005] This prior art is directed to an unsmoothed slope or a slope that has been smoothed by cutting off soil or the like. Construction on the slope may be required, such as providing an anchor for fixing to the surface. Therefore, the present inventors have conceived of applying this prior art to a slope where a legal framework is constructed.

[0006]

However, in the prior art equipment, the legal framework hinders the movement of the construction equipment, and depending on the type of the legal framework, the vertical position where the construction equipment can be moved is limited, Or it was clear that the construction equipment could not be raised and lowered.

As described above, if the elevation position of the construction apparatus is limited by the type and arrangement of the legal frame, the workable range is naturally limited, and it may not be possible to position the construction machine at a desired position.

[0008] Accordingly, a main object of the present invention is to propose a construction facility and a construction method on a slope, which can perform construction in a wider area on a slope where a slope is constructed.

[0009]

[0011]

Embodiments of the present invention will be described below in detail with reference to the accompanying drawings.

<Example of construction equipment>

First, an example of a construction apparatus which is a main configuration of the present invention will be described. FIG. 1 is a construction apparatus example 1 according to the present invention.
0 shows a side view, FIG. 2 shows a front view, and FIG. 3 shows a plan view (front side with respect to a slope). The base 10A of the construction apparatus 10 is a four-wheeled vehicle having wheels 10T, 10T,... At four corners of a rectangular frame as shown in FIG. The interval between the left and right wheels 10T, 10T may be appropriately determined. However, in consideration of application to a slope on which a grid-like method frame is constructed by a free frame method or the like, as will be described later, the left and right wheels 10T are set. , 10T are preferably set so as to be able to be placed on portions NW2, NW2 that are continuous in the height direction of the slope in the slope.

For this reason, as shown in FIG. 5, it is preferable that the distance between the left and right wheels 10T is variable. In this illustrated example, as shown in FIG.
The telescopic pipes 10P, 10P are used for each frame before and after, and the jack 1 is arranged so that the telescopic pipes 10P, 10P can be expanded and contracted.
0J and 10J are provided.

In the present construction apparatus 10, a drilling machine (construction machine)
In order to enable the sliding movement of the base 10A with respect to the base 10A, a slide base 10C is supported on the base 10A so as to be slidable only in the left-right direction of the base 10A. 10A are connected to each other by a slide jack 10D extending in the left-right direction. The slide base 10C is formed of a rectangular frame as shown in FIG. In the illustrated example, the slide table 1
A pair of connecting tools 10L and 10R are fixedly provided at both ends of the front of the OC, and a pair of winches 12L and 12R are provided therebetween.
R are fixedly provided. These functions will be described later.

Further, in the construction apparatus 10, in order to enable the drilling machine 10B to pivot with respect to the base 10A, in the illustrated example, a pedestal D is fixedly provided substantially at the center of the upper rear portion of the slide base 10C. , The rotating shaft R
1 is provided on the upper surface of the slide table 10C.
The turning rail 10G is fixedly provided so as to be continuous from one end in the width direction of the construction device 10 to multiple ends in a fan shape with the center as a center. Further, the swivel table 10E is configured to be rotatably supported on a rotation axis R1 of the slide table 10C, and the tip of the swivel table is configured to move along the swivel rail 10G. D and the swivel base 10E are connected by a swivel jack 10F. FIG. 7 shows only the swivel 10E.

In this embodiment, a drilling machine 10 is mounted on the swivel table 10E.
B is attached. The drilling machine 10B is connected to a back stay 10U fixed on the swivel 10E, a leader 10V supported by the back stay 10U, a power source 10W sliding along the reader 10V, and the power source 10W. And a driven and driven excavation shaft 10X. FIG. 8 shows only the drilling machine 10B. 2, 3, 5, 8, 9, 10, 12, 1.
3, FIG. 15 and FIGS. 21 to 25 do not show the reader 10V, the power source 10W, and the excavating shaft 10X.

Thus, in the present construction apparatus 10, as shown in FIG. 9, the slide table 10C, the swivel table 10E, and the drilling machine 10
B can be integrally slid with respect to the base 10A in the left-right direction (in the state of being attached to the equipment, in the horizontal direction of the slope).

Also, as shown in FIG.
The turntable 10E and the drilling machine 10B according to the expansion and contraction of 0F.
Can be integrally turned with respect to the base 10A (in a state of being attached to the facility, in parallel with the slope).

In particular, if the drilling machine 10B can be slid and turned, the base 10 of the drilling machine 10B can be moved.
There is an advantage that the moving range for A, that is, the range in which drilling can be performed by the drilling machine 10B without moving the entire construction apparatus 10 (hereinafter referred to as a workable range) is widened. In addition, since the slide movement and the turning movement of the drilling machine 10B in the present construction apparatus 10 are movements substantially parallel to the slope when the construction apparatus 10 is attached to the construction equipment, the positioning of the drilling machine 10B is performed. Easy to do.

However, according to the present invention, the drilling machine may be directly mounted on the slide table 10C without providing the swivel table 10E in the above example, so that only the sliding movement of the drilling machine is possible. (Not shown). Conversely, although not shown, the swivel table 10E may be directly mounted on the base 10A without providing the slide table 10C in the above example, so that only the swivel movement of the drilling machine can be performed. .

<Examples of construction equipment and construction method adopting the first example of elevating means> Next, together with specific examples of the elevating means of the present invention, construction equipment on a slope using the above-described construction apparatus and its method Will be described. 11 to 13
Has a plurality of portions NW2 and NW2 continuous in the height direction of the slope at intervals in the horizontal direction of the slope, and has portions NW3 and NW3 continuous in the horizontal direction of the slope in the height direction of the slope. 1 shows an example in which a construction facility 1 according to the present invention is provided on a slope N on which a plurality of lattice-shaped legal frames NW (eg, a legal frame by a free frame method) are constructed.

In the illustrated embodiment, as described above, the construction apparatus 10
A pair of connecting tools 10 is provided at both ends of the front of the slide base 10C.
L and 10R are fixedly mounted apart from each other, and a pair of hoists (winches) 12L and 12R are fixedly provided between them.

The construction apparatus 10 according to the present embodiment is movable on the slope N at least along the height direction of the height direction and the horizontal direction. For this reason, the construction apparatus 10 is configured to use the adjacent height direction continuous portion N in the legal frame NW.
W2, NW2, one of the wheels 10T on the left side of the base 10A,
10T is placed, and the right wheels 10T, 10T are placed on the other continuous portion NW2.

Further, a pair of pulleys 11L, 11R (constituting a guide portion) are connected to the uppermost portion NW1 of the legal frame, and traction wires 13 from the hoisting machines 12L, 12R are connected.
The leading ends of L and 13R are guided by pulleys 11L and 11R, respectively, and connected to connecting tools 10L and 10R provided on a slide base 10C of the construction apparatus 10, respectively.

Preferably, as shown in FIG. 14, the embedding bolt B is provided at a predetermined position on the crest face F1 of the uppermost frame NW1.
1 is embedded with the bolt portion protruding, and the fixing body 20 having an L-shaped cross section is inserted through the bolt insertion hole into the embedded bolt to make contact with the law head FW and the upper surface F2 of the legal frame uppermost portion NW1. The fixing nut N1 is screwed into the embedded bolt B1. Thus, the fixed body 20 is fixed to the legal frame uppermost portion NW1.

In order to increase the fixing strength of the fixed body 20, as shown in FIGS. 11, 12 and 14, the connecting members 22L, 22R of the auxiliary wires 31L, 31R are provided on the face of the forehead of the fixed body 20. Is provided, and this connecting tool 22L,
22R and trees W, W... (Which may be anchors separately provided at the same position) existing on the slope or the forehead above the uppermost frame NW1 may be connected by auxiliary wires 31L, 31R. it can.

On the other hand, a connecting member 21L, 21R of a pair of main wires 30L, 30R is fixed to the bottom surface of the fixed body 20, and the main wires 30L are connected to the connecting members 21L, 21R. , 30R, a pair of pulleys 11L, 11R functioning as constant pulleys are connected respectively. The fixed body 20 is, as shown in FIG.
In addition, at least in the construction equipment 10
Is fixed during the elevating operation of. In addition, pulleys 11L and 11R
Is preferably provided at a higher place on a slope than at a site to be processed by the processing apparatus 10.

As a result, the pulleys 11L, 11R connected to the hoisting machines 12L, 12R fixed to the base 10A of the construction apparatus 10 and the legal frame NW via the main wires 30L, 30R and the fixed body 20. The connecting tools 10L and 10R fixed to the base 10A of the construction apparatus 10 are connected by the pulling wires 13L and 13R in this order.

In particular, in the case where the slope N on which the frame NW is constructed as in the present invention is targeted, at least the construction apparatus 10
Of the main wires 30L,
30R and pulling wires 13L, 13R are framed by NW
It is preferable to keep it away from the surface so as not to contact the legal frame NW. Thereby, the main wires 30L,
30R and traction wires 13L, 13R
Wear or damage due to contact with W and breakage can be prevented.

Thus, by operating each of the hoisting machines 12L and 12R to wind or unwind the pulling wires 13L and 13R, the construction apparatus 10 travels on the height direction continuous portions NW2 and NW2 of the legal frame NW. It is possible to move up and down along the slope N while doing so. At this time, the legal framework NW
Is used as a support for hoisting, so that the construction apparatus 10 can be moved up and down more stably and safely.

In the present invention, while performing the lifting and lowering sequentially,
At each predetermined position, drilling of the anchor hole AH1 can be performed by the drilling machine 10B. Also, the construction device 1
0 on another legal frame, and each hoisting machine 12
By adjusting the amount of winding or rewinding of the pulling wires 13L, 13R by the L, 12R, the construction device 1 can be placed on the left or right side of the position immediately below the fixed body 20.
Drilling can be performed in the same manner while raising and lowering 0 along the slope height direction.

For example, when drilling an anchor hole at an intersection in the grid-like method frame NW, the construction apparatus 10 is moved to a predetermined position in the height direction of the slope by the above-described elevation.
At this time, the hole drilling range of the hole drilling machine 10B is taken into consideration, and the hole drilling target portion is set within the range. In the illustrated example, two drilling portions adjacent in the horizontal direction of the slope (the center of the intersection of the slopes) are in the drillable range of the drilling machine 10B. Thereafter, as shown in FIG. 13, the drilling shaft (not shown) of the drilling machine 10B is moved to one of the drilling sites AH1 by at least one of the sliding movement and the turning movement of the drilling machine 10B.
Then, as shown in FIG. 15, the drilling axis of the drilling machine 10B is positioned at the other drilling portion AH2, and drilling is performed. This order may be reversed.

By performing the construction as described above, the construction apparatus 10 is moved up and down while traveling on the legal frame NW.
Even when the elevation position of the construction device 10 in the horizontal direction of the slope N is limited, construction can be performed over a wider range. Specifically, as described above, the construction can be performed at a plurality of positions without moving the construction apparatus 10, and thus the construction can be speeded up. On the other hand, other lifting means and the like that can be employed in the equipment and method of the present invention will be described below.

<Support Form of Construction Apparatus in Emergency, etc.> In the above example, construction apparatus 10 has main wires 30L,
Although it is supported in the height direction of the slope by the 30R and the pulling wires 13L and 13R, when the wires break or the like, the construction apparatus 10 falls and is extremely dangerous. Therefore, it is preferable to provide preliminary supporting means to support the construction apparatus 10 in the height direction of the slope only in such an emergency.

In the equipment adopting the first example of the elevating means shown in FIGS. 11 to 14 as the supporting means, the supporting rod 4
0 is connected to the uppermost portion NW1 of the legal frame, and a clamping device 50 for clamping and fixing the other end of the support rod 40 only in an emergency is provided by the installation device 10.
Are fixedly provided.

More specifically, as shown in FIGS. 14 and 16, the base member 60
Is fixed, and the rod clamp 61 is
The support rod 40 is rotatably supported in parallel with the slope, and one end of the support rod 40 is clamped and fixed by the rod clamp 61. Thus, the support rod 40 is connected to the legal frame uppermost portion NW1, and is swingable around the coupling portion (the center of rotation of the rod clamp) in parallel with the slope.

The clamping device 50 is shown in FIGS.
As shown in FIG. 5, a base member 51 fixed to the lower side of the base 10A of the construction apparatus 10 and a clamp part 52 supported by the base member 51 so as to be rotatable in parallel with the slope. As shown in FIGS. 19 and 20, the clamp portion 52 is supported by the base member 51 and has a cylindrical portion 52A through which the other end of the support rod 40 is inserted with play, and an inner surface of the cylindrical portion 52A. The wedge body 52B is arranged to be inserted between the outer surface of the support rod 40 and jacks 52C, 52C into which the wedge body 52B is inserted.

In the illustrated example, the cylinders S, S of the jacks 52C, 52C are fixed parallel to the outer surface of the cylindrical portion 52A,
On the other hand, the expanding and contracting jack poles P, P are loosely fitted in the cylindrical portion 52A and connected to the pushing member 52D in contact with the rear surface of the wedge body 52B, and as shown in FIG. When the member 52C is contracted, the wedge 52B is inserted between the inner surface of the cylindrical portion 52A and the outer surface of the support rod 40 via the pushing member 52D, and the support rod 4
0 is clamped and fixed. Also,
Conversely, when the jacks 52C, 52C are extended from this clamped state, the pushing member 52D is separated from the rear surface of the wedge body 52B, and the insertion force does not act on the wedge body 52B.

Of course, the jack poles P, P
The wedge body 52B can be connected to the 2B and can be inserted and removed according to the expansion and contraction of the jacks 52C and 52C.

In this case, when serrations X are formed on the inner surface of the cylindrical portion or the surface of the wedge body which comes into contact with the outer surface of the support rod as shown in the figure, the clamp can be securely and firmly fixed. Further, the jacks 52C, 52C are configured to be remotely controllable (not shown).

Thus, when an emergency such as a broken wire occurs, the worker monitoring the condition of the construction equipment at the bottom of the jack or the like can be used as necessary by jacks 52C, 52C.
Is contracted, and the support rod 40 is
Is clamped and fixed, the construction apparatus 10 and the legal frame NW are connected by the support rod 40, and the construction apparatus 1
0 can be supported in the slope height direction. Conversely, when the jacks 52C, 52C are extended, the pushing member 52D separates from the rear surface of the wedge body 52B as described above, and the wedge body 52B
Since the insertion force no longer acts on the wedge body 52 as shown in FIG.
B is removed from between the inner surface of the cylindrical portion 52A and the outer surface of the support rod 40, and the support rod 40 is attached to the cylindrical portion 52 of the clamp device 50.
It will return to the state where it was inserted with play into A.

It is to be noted that the support rod 40 maintains a state of being inserted with a play into the cylindrical portion 52A of the clamp device 50 during the elevating operation of the construction device 10, preferably at all times, so that it can be clamped at any time. We recommend that you keep it.

On the other hand, the support means at the time of emergency or the like can be applied to the second to sixth examples of elevating means described later. In addition, in the support means in the case of emergency, etc.,
Contrary to the above-described example, the clamp device 50 may be provided on the legal frame, and the above-described rod clamp 61 and the like may be provided on the construction device.

<Second Example of Elevating Means> As shown in FIG. 21, the second example of elevating means is connected to trees W, W, etc. above the uppermost frame NW1 through the main wires 30L, 30R. The pulleys 11L and 11R are connected to each other, and the hoisting machines 12L and 12R fixed to the construction device 10 are configured to raise and lower the construction device 10 without supporting the legal frame NW at all.

<Third Example of Elevating Means> In the above-described first example of elevating means, the hoisting machines 12L and 12R are fixedly provided on the construction apparatus 10 and the frame N
Although the guide is fixedly provided with respect to W, the guide may be reversed.

That is, as shown in FIG.
And a pair of pulleys 14L and 14R (constituting a guide portion) are respectively provided on the base 10A of the base frame 0A and the top NW of the legal frame.
A pair of hoisting machines 12L and 12R are fixedly provided for 1 (the height position does not matter as long as it is higher than the construction target site by the construction apparatus 10 on the slope N). Also, the pulling wires 13L, 1 of the hoisting machines 12L, 12R.
The 3R is guided by the pulleys 14L and 14R of the construction device 10, respectively, and is fixed to the legal frame portion NW1 on the slope N higher than the site to be constructed by the construction device 10 respectively. Thus, by winding the pulling wires 13L, 13R by the hoists 12L, 12R,
The construction apparatus 10 can be moved up and down in the height direction of the slope by using the method frame NW as a support for hoisting. At this time, pulley 14
L and 14R function as a moving pulley.

<Fourth Example of Elevating Means> As shown in FIG. 23, the uppermost part of the sloping frame NW1 (the height position does not matter as long as it is higher on the slope than the part to be constructed by the construction apparatus 10). A pair of hoisting machines 12
L, 12R are fixedly provided, respectively, and the hoisting machines 12L, 1
The 2R traction wires 13L and 13R are connected to the construction device 10
Can be fixed to the base 10A.
Also in this case, by winding or unwinding the pulling wires 13L and 13R by the hoisting machines 12L and 12R, the construction apparatus 10 can be raised and lowered in the height direction of the slope with the legal frame NW as a support for the winding. .
In the present embodiment, since the pulling wires 13L, 13R from the hoisting machines 12L, 12R are directly connected to the construction device 10, respectively, the pulleys 11L, 11R (or 14L, 1R).
4R) requires a more powerful hoist (and therefore relatively large and expensive) compared to the previous example using 4R). Therefore, it is recommended to use the above-mentioned or later-described pulley adoption mode in which a small and inexpensive hoist can be used.

<Fifth Example of Elevating Means> The hoisting machine can be fixed to the slope. For example,
As shown in FIG. 24, the legal frame uppermost portion NW1 (the construction device 10
The height position may be anywhere as long as it is higher on the slope than the construction target site according to (1).
1R, and preferably, a pair of hoisting machines 12L, 12L,
12R is fixedly provided, and the pulling wires 13L, 13R of the hoisting machines 12L, 12R are guided by pulleys 11L, 11R connected to the legal frame NW and are connected to the construction device 10 to be hoisted. With the machines 12L and 12R, the construction apparatus 10 can be moved up and down with the legal frame NW as a support.

<Sixth Example of Elevating Means> FIG. 25 shows an embodiment using a fixed pulley and a moving pulley. In the sixth example of the lifting / lowering means, the construction apparatus 10
Pulleys 14L and 14 functioning as moving pulleys on the base 10A
R (constituting the guide portion) is provided, and the pair of pulleys 11L and 11R functioning as fixed pulleys are placed at the top NW1 of the sill frame (the height position if it is higher on the slope than the site to be installed by the installation device 10). It is more preferable that a pair of hoisting machines 12L and 12R be fixed to a slope lower than the construction target site by the construction apparatus 10.

Then, the pulling wires 13L, 13R of the hoisting machines 12L, 12R are guided in this order by the fixed pulleys 11L, 11R connected to the uppermost frame NW1, and the moving pulleys 14L, 14R fixed to the construction device 10. Then, it is connected to the uppermost frame NW1 again.

Thus, by operating each of the hoisting machines 12L and 12R to wind or unwind the pulling wires 13L and 13R, the construction apparatus 10 can be raised and lowered along the slope N with the legal frame NW as a support. it can.

In this case, since the fixed pulleys 11L and 11R and the moving pulleys 14L and 14R are used, the hoisting machines 12L and 11R are used.
It is sufficient that the hoisting force by the 12R is smaller than that of the above-described example, and the hoisting machines 12L and 12R can be further reduced in size. Although not shown, the number of moving pulleys can be similarly increased, and in this case, the hoist can be further reduced in size.

Although various examples of elevating means have been described above, the present invention is not limited to the case where construction is performed on a slope while moving the construction apparatus along the slope on which the slope is constructed. Because it is good, it is not limited to one that moves up and down along the height direction of the slope. Therefore, the present invention can be applied to equipment having means for moving the construction apparatus 10 along the horizontal direction or along another direction.

<Others> In the above example, instead of the pulling wires 13L and 13R, long pulling members such as ropes and chains can be used. In the present invention, these are collectively referred to as pulling wires. As the hoists 12L and 12R, a so-called chain block, turnbuckle, or the like can be used in addition to a winch.

It goes without saying that a plurality of the above pulling wires may be used on the right or left. Therefore, a plurality of hoists can be provided on one side.

The normal frame in the illustrated example is a grid-like normal frame composed of portions continuous in the height direction of the slope and in the horizontal direction. However, the legal frame of the present invention also includes a so-called legal frame block (such as a cross shape or a rectangular shape).

When the work is completed within a certain span in the width direction of the slope, the above-mentioned fixed body 20 (or the hoist when the hoist is not fixed to the work apparatus), A similar construction can be performed after the installation position is moved to an adjacent span and installed. FIG. 12 shows the fixed body after moving to the left side in the figure as 200L, and the fixed body after moving to the right side in the figure as 200R.

Further, the fixed body 20 can be fixed movably in the width direction with respect to the legal frame. By doing so,
Movement in the width direction is quick.

[0060]

As described above, according to the present invention, construction can be performed in a wider range on the slope where the frame is constructed.
