FIG. As shown in these figures, the slope concrete paving apparatus has a slip foam 10 as a main body, and a distributor 20 for distributing and discharging concrete over the entire width of the slip foam 10, and between the distributor 20 and the pipe K. And a piping extension mechanism 30 that extends to extend the piping K. Therefore, the concrete pumped through the pipe K by the concrete pump is discharged from the distributor 20 through the pipe extension mechanism 30 and is held down by the slip foam 10. The significance of the present invention will be clarified below by taking the case of using this slope concrete paving device for paving concrete impermeable walls of a surface impervious wall type fill dam as an example, by detailing the configuration and operation of each part of the device. .

The slip form 10 is a movable formwork for continuously pressing the concrete discharged on the slope into a flat form, and is a main part of the slope concrete paving apparatus. Basically, the structure is similar to a trolley, and a plate 1 for holding down the upper surface of concrete
5. It has wheels 17 for moving along the rails R with the formwork laid beforehand, and a roof 18 for preventing rain and wind and increasing rigidity. And this slip form 10
Are the winches 11a, 1

A wire rope 13a, 1 having one end thereof fastened to the slip form 10 while its intermediate portion is wound around
The winch 11a, 11b winds the other end of 3b, respectively, so that the slip form 10 moves upward from below on the slope.

Further, the slip form 10 is provided with a vibrator 14 for compacting the concrete discharged from the distributor 20. The vibrator 14 has a configuration in which a frame body that bundles the vibrating rods 14a to 14e slides along the rail 19 by engagement of a rack and a pinion.
e also moves up and down with respect to the frame by engagement of the rack and the pinion. Therefore, the vibrator 14
Is made so that each of the vibrating rods 14a to 14e can be horizontally slid over the entire width of the slip form 10 and independently moved up and down, so that the concrete just discharged from the distributor 20 can be properly tightened all over. Can be hardened. Then, the concrete compacted by the vibrators 14a to 14e is pressed down on its upper surface by the plate 15 at the bottom of the moving slip form 10, and is laid flat continuously. At this time, since both sides of the concrete are clogged by the side frame 40 (see FIG. 6) of the rail R with a frame, when the slip form 10 passes, the concrete is formed and the concrete impermeable wall is completed.

The distributor 20 is connected to the straight pipe 2.
1 and a bend pipe 22 are connected so that they can be freely twisted to each other, and an arm 23 for holding the straight pipe 21a so as to rotate about the o-axis, and a straight pipe 21b serving as a pipe opening are connected to a rail. And a slider 25 that slides laterally along the slide 24.
Discharges over the entire width. And the movable part of this distributor 20 is o
The portion from the shaft to the mouth (see FIG. 1), and the other portions are fixed to the slip foam 10. Also,
The straight pipe 21b serving as the pipe opening is moved by the slider 25 to the rail 2
It can be slid horizontally to the full length of four.

In the present embodiment, the slider 25 having power moves along the rail 24, and the arm 23 rotates around the o-axis so as to follow the slider 25. The present invention is not limited to this, and if the above-described function of the distributor 20 is exhibited, the arm 23 having power conversely rotates the straight pipe 21a around the o-axis and follows it. The slider 25 may be configured to slide along the rail 24. In addition, the arm 23 and the slider 2
Both of them may be equipped with power, or none of them may be equipped with power and the other parts may be equipped with power to perform the same operation.

The pipe extension mechanism 30 includes a slip form 1
The pipe K for pumping concrete from the concrete pump (not shown) to the slip form 10 with the movement of 0
This is a mechanism that aims to extend. The pipe extension mechanism 30 in the present embodiment connects the straight pipe 31 and the bend pipe 32 so that they can be freely twisted to each other as appropriate, and moves the straight pipe 31a in the middle thereof up, down, left and right, and this hoist 33. An inverted L-shaped frame 34 suspending the pipe 33 and a valve 35 for blocking the flow of concrete between the pipe K and the pipe extending mechanism 30 are provided.

The hoist 33 can be slid horizontally along the arm 34a of the frame 34, and its hook 33
a can be moved up and down. Then, the pipe extension mechanism 30 expands and contracts like a scale insect with the movement of the hoist 33.

When a spare concrete transport pipe is to be added between the valve 35 and the pipe K in order to extend the pipe K, the connecting portion must be disconnected once. At this time, it is natural that the operation of the concrete pump must be stopped. However, in consideration of the slope slope, the valve 35 is set to prevent the concrete remaining in the pipe extension mechanism 30 from flowing out. It is necessary to tighten.

A method of extending the pipe K using such a pipe extension mechanism 30 will be described with reference to FIG. FIG. 3A shows a state in which the pipe extension mechanism 30 is contracted. From this state, the slip form 10 moves little by little to the state shown in FIG. Here, in order to extend the pipe K, the movement of the slip form 10 and the operation of the concrete pump truck P are stopped, and the valve 35 is closed.
Then, at a connecting portion 36 between the valve 35 and the pipe K, the two are separated, and as shown in FIG.
The pipe extension mechanism 30 is contracted while the position of 0 is kept as it is, and this is pulled together with the valve 35 to the slip form 10 side. Then, when there is a space in which one spare concrete transport pipe k can be inserted, the concrete transport pipe k is inserted and connected there (see (d) of the same). By performing the steps (a) to (d) in this manner, the pipe K is extended by the length of the concrete transport pipe k.
Next, the valve 35 is opened, and the movement of the slip form 10 and the operation of the concrete pump truck P may be restarted.
In order to further extend the pipe K, the procedure of (a) to (d) may be repeated, starting from extending the pipe extension mechanism 30 as shown in (e).

A plurality of spare concrete transport pipes k are mounted on the slip form 10 as shown in FIG. Then, as a work space for unloading these concrete transport pipes k and adding them to the connecting portion 36, and for work such as ironing, spraying of a curing agent and various maintenances, work is performed on four sides of the slip form 10. A scaffold 16 is provided. Further, the arm 34a of the frame 34 is rotatable around a pole 34b in order to easily add the loaded concrete transport pipe k to the connecting portion 36.
The connecting portion 36 is brought on the work scaffold 16 so that a is directed toward the center of the slip form 10.

In this embodiment, the slip form 10 moves on a slope along a rail R with a formwork similar to the conventional one, but this rail R with a formwork is connected by a cotter so that its position and direction can be adjusted.・ Fixed. This will be described with reference to FIGS. First, FIG. 6 is a partial plan view illustrating a laying state of the rail R with a formwork. As shown in the figure, the form-fitting rails R are laid in parallel in two rows on both sides of the casting block D, and include an inner side formwork 40 and an outer rail 41.

Here, as can be seen from FIG. 7A which is a partial detailed plan view of a portion for fixing the rail 41 in FIG. 6, and FIG. Rail 41
Is an H-shaped steel, which is supported by a sleeper 42 in which channel steels 42a, 42a are back-to-back, and is connected thereto by bolts 43. Bolts with brackets 44 are fixed to both ends of the gap between the channel steels 42a by welding. The bolt 44 with a bracket is fixed to a base metal 45 by a drift pin 46, and the base metal 45 is fixed to the ground by an anchor bar 47.

At this time, the base fitting 45 and the anchor rod 47
As shown in the figure, a cotter 49a, 49a is connected to the axis of the rail 41 on a horizontal plane in a direction orthogonal to the axis of the rail 41 (horizontal direction in the drawing) via a rail fixing bracket 48 as shown in the figure. Therefore, for example, if the rightmost cotter 49a in FIG. 7A is hit and pushed in the direction of the arrow, the anchor rod 47, the bolt with bracket 44, the sleeper 4

The position of the rail 41 in the direction orthogonal to the axis of the rail 41 (horizontal direction in the drawing) on the horizontal plane is adjusted by 9b. Furthermore, a bolt 44 with a bracket and a base fitting 45
Are connected so that the relative height can be adjusted by height adjusting nuts 44a and 44b. Therefore,
Fine adjustment of the bend and position of the rail 41
9b and the height adjustment nuts 44a and 44b can be easily operated.

FIG. 8A is a partially detailed plan view of a portion for fixing the side mold 40 of FIG. 6, and FIG. 8B is a cross-sectional view taken along the line BB 'of FIG. As shown in these figures,
The side formwork 40 is provided with a rail 41 via a bracketed steel pipe 50 in which an L-shaped bracket is welded and fixed to one end of the steel pipe.
Are connected and fixed so as to be adjustable in position. A pin 51 is welded and fixed to a bracket portion of the steel pipe 50 with a bracket, and is connected to a form fixing metal fitting 52 welded and fixed to the side surface form 40 via a cotter 53a. Further, the steel pipe portion of the steel pipe with bracket 50 is provided with a cotter
3b, the steel pipe portion of the steel pipe 50 with bracket is connected and fixed to the rail 41 by tightening the steel pipe part from both sides with a bolt 56 via a grip metal 55 for gripping a lower flange of the rail 41.

Here, the cotter 53a plays a role of fixing the side mold 40. If the cotter 53a is hit and pushed in the direction of the arrow in FIG. Bracketed steel pipe 50 via fixing bracket 52
Firmly fixed to At this time, even if the bracket-fitted steel pipe 50 is inclined with respect to the side mold 40 as shown by the imaginary line in the figure, it is easy to press the cotter 53a to fix the side mold 40. . Also, the cotter 53b plays a role of fixing the bracket-attached steel pipe 50. If the cotter 53b is hit and pushed in the direction of the arrow in FIG. 8B, the bracket-attached steel pipe 50 is firmly fixed to the plate 54. Is done. At this time, the adjustment in the left-right direction in the figure is easily performed by adjusting the position of the plate 54 in the steel pipe portion of the steel pipe 50 with the bracket and pushing the cotter 53b.

Next, a description will be given, with reference to FIG. 9 and FIG. 10, of the slip-form conveying means installed and fixed at the top of the slope. FIG. 9 is a perspective view showing a movable trolley 60 as a slip-form carrying means, and FIG. 10 is a side sectional view showing a fixed state thereof. As shown in FIG.
Reference numeral 0 denotes a trolley truck 62 having wheels 61 and a tower 63 assembled on the trolley truck 62, and a trolley rail 6 laid along the top of the slope.
4 along wheels 4. The sheave 12a (12b) provided at the top of the tower 63 has a winch 11a (11
b) the wire rope 13a (13
b) is multiplied. A weight 65 is provided on the trolley 62 so as not to be dragged by the weight of the slip form 10. Further, as shown in FIG. 10, the tower 63 is anchored to the foundation concrete 68 constructed on the top of the slope by the turnbuckle 66, and the trolley 62 is anchored by the chain 67.

The moving trolley 60 thus constructed
Plays a role of taking a reaction force when the slip form 10 moves along the slope, and after the slip form 10 finishes ascending on the slope, puts the whole of the slip form on the turret section 63 and places it on the next casting block D. It is to move to. Therefore, the normal moving trolley needs to have the same weight as the slip form 10 or the like, but the moving trolley 60 shown in the drawing is extremely extremely large in that the weight 65 is simply mounted on a frame combining H-shaped steel and the like. It has a simple configuration, and its total weight is significantly lighter than the slip form 10 or the like. This is because the anchor is fixed to the foundation concrete 68 constructed on the top of the slope by the turnbuckle 66 and the chain 67. When the moving trolley 60 moves, it goes without saying that the turnbuckle 66 and the chain 67 are removed.

The winches 11a and 11b for moving the slip form 10 and the distributor 2
Slider 25 or arm 23 for deforming 0
The operation of the hoist 33, the valve 35, and the vibrator 14 for expanding and contracting the pipe extension mechanism 30 can be centrally controlled from a remote location away from the embankment as needed. Therefore, these operations are labor-saving, and are performed safely and without waste according to the work progress.

<Embodiment 2> Next, another embodiment of the slope concrete paving apparatus according to the present invention will be described with reference to FIGS.

Oscillating chutes 27, 27 for distributing and discharging in front of the foam 10, and a guide beam 28 for sliding the tips of the oscillating chutes 27, 27 to the full width of the casting block D. .

Here, as shown in FIG. 12B, which is a cross-sectional view taken along the line AA 'of FIG.
The chutes 27a and 27b are stacked one on top of the other
The configuration is such that it can be slid freely with c, so that the entire length changes. The guide beam 28 has a built-in power transmission mechanism (not shown).
The tips of b and 27b are slid in the width direction of the casting block D. Since the base ends of the chutes 27a, 27a are rotatably joined to the distributor cart 26, the concrete fed through the pipe K can be smoothly distributed and discharged to the front of the slip form 10. Further, unlike the conventional chute method, in this slope concrete paving apparatus, concrete is merely pumped from below the slope and distributed by the swinging chute 27 having a short overall length, so that concrete separation does not occur. A switching valve Ka is provided in the middle of the pipe K, and the swing valve 2 is operated by operating the switching valve Ka.
7 can be selected.

Next, the slip form used here will be described. FIG. 13 is a plan view showing the slip form 10 indicated by a virtual line in FIG.
FIG. 14 is a side view thereof. This slip form 10
Has a configuration substantially similar to that of the slip form 10 described in the first embodiment, but has a reel 70 for winding the power cable 69 and the like, and is applicable to a wide casting block D. It can be used for huge dam construction. Therefore, the power cables 69 laid on both sides of the casting block D can be wound up with the movement of the slip form 10, so that the paving work can be performed safely and smoothly.

The configuration and operation of the slope concrete paving apparatus according to the present invention have been described above with reference to the two embodiments. However, the shape and material of each component play a role required for each component. The present invention can be changed to other forms as long as it is more than a certain number, and the present invention is not limited to those shown in the present embodiment. That is, for example, the structure and the moving method of the slip form 10 and the structure and the deformation mode of the distributor 20 and the pipe extension mechanism 30 can be freely determined on condition that they have the required functions. Note that the slip form is not limited to one that rises from below along a slope, and may be one that descends from above. The concrete pump may be installed not only below the slope but also above the slope.
