Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for leveling a submerged rubble layer used for constructing a reclamation seawall or a breakwater, and more particularly to a submersible rubble layer suitable for use in leveling a rubble layer. The present invention relates to a method and an apparatus.

[0002]

2. Description of the Related Art For example, in order to reclaim the ocean, a rubble mound is formed by first injecting crushed stones into the sea floor.
Next, a caisson is continuously installed on this rubble mound, and further, a burial stone etc. is backed inside this caisson to form a backing stone layer, and these rubble mound, caisson, backing stone layer are used as revetment. After that, sediment is dumped into the inner sea area (inland sea) surrounded by the seawall and replaced with seawater. In such a landfill method, the stability of the rubble stone layer is secured not only at the top of the rubble stone mound to be the installation surface of the caisson, but also at the slope of the rubble stone mound and the backing stone layer (rubble stone layer), Alternatively, leveling must be carried out for the purpose of laying a sand-prevention sheet for preventing landfill sand from flowing into the open sea.

[0003] By the way, the leveling of the top of the rubble mound has been conventionally performed using various leveling machines, but the leveling of the rubble mound and the backing stone layer has not been performed. Because there is no suitable leveling machine, divers generally rely on leveling work, which not only takes a long time, but also poses a problem in terms of safety. Was.

For example, Japanese Patent Publication No. Hei 6-33602 discloses a leveling machine provided with a plurality of downward blades and a leveling roller, which is suspended from a ship by a rope and operated along a slope by operating the rope. There has been proposed a leveling method in which a leveling machine is moved.

[0005]

However, according to the leveling method described in the above-mentioned publication, the hull is moved in order to move the leveling machine at a constant height on the slope while maintaining the leveling machine in a constant posture. However, it is necessary to perform a troublesome operation of adjusting the amount of feeding or winding of the rope, and there is a problem that workability is extremely poor. In addition, since the leveling machine is simply hung by a rope, if it hits a large rubble or a large projecting rubble, its posture and height (position)
However, there is a problem that it is difficult to stably perform rubble leveling.

The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide an underwater rubble leveling method which can be easily operated and can be leveled irrespective of the form of rubble. And to provide a device.

[0007]

In order to achieve the above object, a method of the present invention is to install a guide frame on a rubble layer to be leveled so as to be parallel to a planned leveling surface. Moving the moving body along, and leveling the rubble layer by the leveling means provided to the moving body, characterized by being repeated while laterally moving the guide frame, and the present invention The apparatus is provided with the above-described guide frame, moving body, and leveling means.

According to the construction method and the apparatus configured as described above, since the moving body provided with the leveling means is guided by the guide frame, the leveling means (leveling means) can be obtained only by adjusting the installation height of the guide frame. The leveling device moves at a constant height and in a constant attitude, eliminating the need for troublesome rope operation to control the attitude or position of the leveling means, and furthermore, the leveling means escapes even if it collides with rubble. There is no.

In the apparatus according to the present invention, the guide frame is formed of a frame, the moving body is supported by the left and right beams of the frame in a double-supported state, and the leveling means is mounted on the moving body. Can be moved in a direction perpendicular to the moving direction of the moving object. In the case of such a configuration, the moving body is supported by the frame body in a double-supported state, so that the moving body is less likely to be distorted or deformed even when subjected to an impact, and the leveling means is more reliably in a fixed posture, The height will be maintained. In addition, since the leveling means can travel in a direction orthogonal to the traveling direction of the moving body, the position of the guide frame is kept as it is by shifting the position of the leveling means and running the moving body a plurality of times. A wide range of smoothing can be performed.

[0010] In the apparatus of the present invention, the guide frame selects an arbitrary installation location according to the type of the rubble layer to be leveled, but the rubble layer to be leveled is backed in an existing caisson. In the case of a backing stone layer, it is desirable to bridge the guide frame between the existing caisson and the bottom of the backing stone layer. In this case, the installation surface of the guide frame is flat, so that the installation and the lateral movement are easy.

[0011]

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

FIG. 1 shows a first embodiment of an underwater rubble leveling method according to the present invention. In the first embodiment, the backing stone layer 3 of the caisson 2 installed on the rubble mound 1 is leveled, and the lining stone layer 3 is placed on the slope of the rubble mound 1. Crushed stones or the like are charged onto the bottom landfill layer 4 buried so as to be almost the same height as the top end, so as to form a predetermined inclination angle. The caisson 2 on the rubble mound 1
a is exposed above the water surface, and forms a reclamation revetment 5 integrally with the backing stone layer 3. The landfill soil layer 4
Is provided as a bottom surface 6 of the backing stone layer 3.

When the present method is carried out, a leveling rake 1 as leveling means is separately provided on a frame-shaped guide frame 11.
A rubble leveling device 10 (to be described in detail later) in which a moving body 14 having a roller 2 and a pressure roller 13 is movably mounted is prepared, and the rubble leveling device 10 is mounted on a crane (not shown) on a work boat. And installed on the landfill revetment 5. Extendable support legs 15 are provided at the four corners of the guide frame 11. When the rubble leveling device 10 is installed, these support legs 15 are attached to the upper surface 2 a of the caisson 2 and the bottom surface of the backing stone layer 3. 6 so as to bridge the guide frame 11 between them. Each support leg 15 is configured to extend and contract, for example, using a cylinder as a drive source. By adjusting the amount of extension and contraction of these support legs 15, the main body 11 a of the guide frame 11 can be moved to the backing stone layer 3. Plan leveling surface S
Is positioned so as to extend in parallel from the predetermined height. In addition,
Both ends of the guide frame 11 provided with the support legs 15 are parallel portions 11b and 11c which are parallel to each other.
In addition, at four places on the upper surface of the guide frame 11, eye plates 16 for hanging wires for suspension are protruded.

In the first embodiment, the caisson 2
A rail 17 is laid on the upper surface 2a of the guide frame 11 so as to extend in the installation direction.
A pair of wheels 18 that can be mounted on the rails 17 is provided on the lower surface of b. The pair of wheels 18 move along the rails 17 according to the shortening of the support legs 15 below the upper end parallel portion 11b.
The guide frame 11 can be moved along the rail 17 in this state. Therefore, when the lower parallel portion 11c of the guide plate 11 is lifted from the method bottom surface 6 via a wire wound on the lower eye plate 16 with the wheel 18 mounted on the rail 17, the guide plate 11 The whole is free to move in a horizontal direction B perpendicular to the leveling direction A.

Here, the moving body 1 of the rubble leveling device 10
4 engages two pairs of wheels 20 provided on the left and right side walls with a pair of upper and lower rails 22 provided on the inner surfaces of the left and right beams 21 of the guide frame 11, respectively, as shown in FIGS. By doing so, it is mounted on the guide frame 11 so as to be able to run. In this case, each wheel 20 of the moving body 14 is engaged with the pair of rails 22 from the inside, so that the moving body 14
It is supported in a two-sided state and immovable in the vertical direction. A pinion 24 that meshes with a rack 23 formed at the base of one of the pair of rails 22 is provided on the left and right side walls of the moving body 14. One of the pinions 24 is rotatably driven by a motor (not shown), and the moving body 14 moves along the left and right beams 21 of the guide frame 11 according to the operation of the motor. I will be.

On the other hand, a leveling rake 12 and a pressure roller 13 as leveling means are mounted on a horizontal moving body 25 movably mounted on the moving body 14 in a direction perpendicular to the moving direction.
It is supported by. More specifically, this horizontal moving body 25
As shown in FIGS. 2 and 3, two pairs of wheels 26 provided on the side wall are engaged with a pair of upper and lower rails 27 provided in the moving body 14, respectively. It is mounted so that it can run. In this case, each wheel 26 of the lateral moving body 25 is engaged with the pair of rails 27 from the inside, so that the lateral moving body 25 is in a state of being held by the moving body 14 in a double-supported state and cannot move in the vertical direction. It has been supported. Thus, on the front and rear side walls of the horizontal moving body 25, the lower flange 14a of the moving body 14 (FIG. 3)
A pinion 29 is provided which meshes with a rack 28 fixedly mounted on the rack. One of the pinions 29 is rotatably driven by a motor (not shown), and the horizontal moving body 25 moves the moving body 1 according to the operation of the motor.
4 to move laterally.

The leveling rake 12 includes a support 32 connected to a bracket 30 provided on the inner surface of the horizontal moving body 25 via a quadrilateral link mechanism 31, and a comb-shaped leveler supported by the support 32. The nail 33 is provided. The quadrilateral link mechanism 31 is connected to an adjusting means 34 extending from the horizontal moving body 25 and comprising, for example, a screw adjusting mechanism. The adjusting means 34 adjusts the tip position of the leveling claw 33. Has become. Further, the pressure roller 13 is
One end is pivotally attached to the other end of a swing arm 36 having one end attached to the horizontal moving body 25 using a shaft 35. A damper 37 extending from the horizontal moving body 25 is operatively connected to the swing arm 36. When a large impact is applied to the pressure roller 13, the damper 37 operates to absorb the impact. It is supposed to be. Note that the moving body 14 may be provided with a surveying means (ultrasonic sensor or the like) 38 for measuring the leveling surface.

In the above-described rubble leveling device 10, the guide frame 11 is formed to have a length of about 45 m and a total width of about 10 m, for example. Leveling rake 12
A moving body 14 having a pressure roller 13 is assembled. Then, the completed rubble leveling device 10 is mounted on a work boat and transported to a construction sea area, and is installed on the landfill revetment 5 by a crane (not shown) on the work boat.
In this installation, the wheel 18 below the upper parallel portion 11b of the guide frame 11 is placed on the rail 17 on the caisson 2 with the support legs 15 shortened in advance, and the upper position of the guide frame 11 is fixed. Later, the support leg 15 is extended to adjust the height position of the main body 11 a of the guide frame 11. The height position of the guide frame 11 is, for example, about 2.5 m higher than the planned leveling surface S. At this time, the moving body 14 is stopped at the standby position on the upper side of the guide frame 11, and the horizontal moving body 25 is moved to one side of the moving body 14.

After completion of the preparation, the motor (not shown) is rotated to rotate the pinion 24, and the moving body 14 is moved downward (leveling direction A) along the guide frame 11 at a predetermined speed. Due to the movement of the moving body 14, the leveling claw 33 of the preceding leveling rake 12 pushes out the rubble projecting from the backing stone layer 3 and falls into an appropriate recess, and the subsequent pressure roller 13 further rolls. Press, thereby smoothing the rake 12
In addition, unevenness in the moving range of the pressure roller 13 is leveled.
When the moving body 14 reaches the lower portion of the guide frame 11 (the lower parallel portion 11c), the motor is reversely rotated to return the moving body 14 to the standby position on the upper side of the guide frame 11, and at this position. Then, the motor for the lateral moving body 25 is rotated to move the lateral moving body 25 laterally by a predetermined distance. This lateral movement distance is equal to the leveling rake 12 and the pressure roller 13.
Is within the range that overlaps the previous movement range, and thereafter, the motor is rotated again to move the moving body 14 to the guide frame 11.
Rake 12 and compaction roller 1
The next unevenness is leveled by 3. When returning the moving body 25 to the standby position, the unevenness of the leveling surface is roughly measured by the surveying device 38, and if the leveling is insufficient, the moving body 14 is located at the same position.
Is moved to perform correction leveling.

In this way, each time the lateral moving body 25 is moved laterally, the moving body 14 is moved and leveled, and when the lateral moving body 25 reaches the lateral movement limit, the upper supporting leg of the guide frame 11 is moved. 15, the pair of wheels 18 is mounted on the rails 17, while the lower parallel portion 1 of the guide frame 1 is
1c is lifted from the buttock surface 4 by hanging it with a wire hung on the eye frame 16. In this state, the guide frame 11 is moved by a crane operation and a wire operation on the work boat in a lateral direction B perpendicular to the leveling direction A by a distance approximately equal to the width, and each support leg 15 is extended at that position. Then, the position of the guide frame 11 is fixed again. The leveling is performed by the leveling rake 12 and the compaction roller 13 while moving the moving body 14 and the horizontal moving body 25 in the above-described procedure, and this is repeated while the guide frame 11 is laterally moved at a predetermined pitch. Thereby, the slope of the backing stone layer 3 is leveled sequentially.

In the first embodiment, the leveling rake 12 and the pressure roller 13 are used as leveling means. However, the type of the leveling means is arbitrary, and Instead of or in common with the pressure rollers 13, for example, a vibration leveling machine can be used. Further, the leveling rake 12 may be configured to include, for example, a flat leveling blade in place of the comb-shaped leveling claw 33.

In the first embodiment, when the guide frame 11 is moved laterally, the lower portion is lifted. However, the method of moving the guide frame 11 laterally is arbitrary. Embodiments as shown in FIGS. 4 and 5 can be employed. Figure 4
The embodiment shown in FIG.
The ballast tank 1c is supported by the ballast tank 40, and the ballast tank 40 is settled on the bottom surface 6 at the time of leveling, and the ballast tank 40 is floated at the time of the lateral movement. Guide frame 11
Does not need to be lifted by a wire, and the lateral movement operation becomes easy.

In the embodiment shown in FIG. 5, a floating body 41 having a lower parallel portion 11c of a guide frame 11 floating on water is provided.
Supported by a wire 43 extending from the upper winch 42,
When the guide frame 11 is moved laterally, the wire 43 is wound around the winch 42 so that the lower portion of the guide frame 11 floats. In this case, only the floating body 41 is moved. Therefore, the lateral movement work is simplified.

FIG. 6 shows a second embodiment of the present invention. A feature of the second embodiment is that a single bar-shaped guide frame 51 is used as the guide frame 51 instead of the frame-shaped guide frame 11 and a leveling means (not shown) is provided. The movable body 52 is mounted so as to be able to travel, and the upper end of the guide frame 51 is supported by a traveling track 53 running on the upper surface 2 a of the rubble mound 2, and the lower end thereof is supported by a frame 55 having support legs 54. . In this case, for example, the gantry 55 is lifted by the crane 57 on the work boat 56, and the work boat 56 is moved, and the traveling track 53 is moved, so that the guide frame 51 can be easily moved laterally. This second
According to the embodiment, since the guide frame 51 has a single bar shape, its manufacture is simplified.

Here, the frame-shaped guide frame 11 and the moving body 14 used in the first embodiment are, as shown in FIG. 7, a slope of the backing stone layer 3 after the rubble leveling. It can be used for laying the sandproof sheet 60 thereon. In this case, the guide body 11 bridged between the upper surface 2a of the caisson 2 and the bottom surface 6 of the backing stone layer 3 is provided with the moving body 14
Of the second moving body 6 using the traveling rail 22 (FIG. 2)
1 so as to be able to run, and at the same time
The second moving body 61 is provided with a support frame 64 that supports a sheet roll 63 around which a sandproof sheet 60 is wound.

More specifically, as shown in FIGS. 8 and 9, the sheet roll 63 is rotated around the distal end of a swing arm 66 having a base end pivotally mounted on both ends of a support frame 64 using shafts 65. It is mounted movably and detachably, and is always mounted on the sheet laying surface 6 by its own weight, as indicated by the dashed line.
7 is grounded. On the other hand, the second moving body 6
1, a hoisting device 68 for lifting the sheet roll 63 as required. The hoisting device 68 includes a take-up drum 69, a suspension wire 70 having one end wound around the take-up drum 69, and one end connected to the second movable body 61 and the other end connected to the suspension wire. And a sling rope 71 hooked around the arm. According to the hoisting device 68, after the sling rope 71 is wound around the sheet roll 63 and the other end is hung on the hanging wire 70 to rotate the winding drum 69, the swing arm 66 moves the shaft 65. Swinging to the fulcrum, the sheet roll 63 can be lifted from the sheet laying surface 67 to an arbitrary height.

The support frame 64 is orthogonal to the traveling direction of the second moving body 61 by engaging wheels 72 provided on both side walls thereof with rails 73 provided below the second moving body 61. It is possible to traverse in the direction. A rack 74 is laid on the upper surface of the support frame 64 so as to extend in the longitudinal direction. The rack 74 is provided in the second moving body 61 and is provided with a pinion 76 ( FIG. 9) is engaged. That is, the support frame 64 traverses arbitrarily by receiving the rotation of the motor 75 via the pinion 76 and the rack 74. A counterweight 78 having a rack 77 on the upper surface is mounted on the second movable body 61 so as to be able to move laterally.
8 also engages a pinion (not shown) rotated by the motor 75 with its rack 77,
Synchronously with the support frame 64, they traverse in opposite directions.

When laying the sheet, the second moving body 61 is previously positioned on the upper surface 2a of the caisson 2 by running the first moving body 14, and the support frame 64 disposed on the second moving body 61 at that position. The sheet roll 63 is attached to the tip of the swing arm 66 extending from the end. After the attachment is completed, the sling rope 71 is wrapped around the sheet roll 63 and hooked on the hanging wire 70, and the winding drum 69 of the hoisting device 68 is rotated to lift the sheet roll 63. , The first mobile unit 14
To move the second moving body 61 to the vicinity of the upper end of the backing stone layer 3. Next, the winding drum 69 is rotated in the reverse direction to loosen the sling rope 71, and the sheet roll 63 is brought into contact with the sheet laying surface 76. Subsequently, the sling rope 71 is detached from the sheet roll 63, and is wound from the sheet roll 63. The free end of the returned sandproof sheet 60 is fixed to the upper end of the backing stone layer 3.

Thereafter, the first moving body 14 is moved downward along the guide frame 11. Then, the second moving body 61 also moves integrally therewith, and the sheet roll 63 rolls on the sheet laying surface 67 by its own weight or while being towed by the support frame 64, and the sandproof sheet 60 is sequentially fed out, It is efficiently laid on the sheet laying surface 67 of the backing stone layer 3. Then, when the laying of one sheet is completed, the lifting device 68 is operated again to lift the tip of the swing arm 66 from the sheet laying surface 67, and the first moving body 14 is moved upward, and the second moving body 14 is moved upward. Is returned to the upper surface 2a of the caisson 2. After this return, the motor 7 in the second moving body 61
5, the support frame 64 is traversed by a predetermined distance, and at that position, the next sheet roll 63 is attached to the tip of the swing arm 66 extending from the support frame 64.
At this time, the support frame 64 is positioned so that the next sandproof sheet 30 overlaps the previously laid sandproof sheet 30 with a predetermined wrap margin, and the above operation is repeated again to lay the next sheet. Since the support frame 64 that supports the sheet roll 63 is provided on the second moving body 61 that moves along the guide frame 11, the sheet roll 63 rolls in a fixed posture without skewing. Therefore, when the sandproof sheet 60 is laid, only a small wrap margin is required, and wasteful use of the sandproof sheet 60 is suppressed.
