Description

  For example, the present invention can be applied to a slope finishing work in a trapezoidal CSG (Cemented Sand and Gravel) dam, a CFRD (Concrete Face Rockfil Dam), or other uplifting work (also referred to as a placement work; the same shall apply hereinafter), It belongs to the technical field of uplifting and compacting.

As shown in Fig. 7, an example of a construction drawing for trapezoidal CSG dams, etc. and slope finish compaction work, as shown in Fig. 7, CSG or soil cement (hereinafter referred to as "sheng") The process of raising and leveling with bulldozer B to a thickness of about 25 cm per layer is repeated for three layers. Thereafter, the step of collectively compacting the three layers (75 cm) with a vibrating roller or the like is repeated, and first, the lower lift of the protective concrete D is formed.
Next, the precast concrete formwork C is installed along the slope of the lower layer lift, and then the upper layer lift is constructed by repeating the three layers of uplifting, leveling and compaction again. The two-layer lift is defined as one lift of the protective concrete D.
Then, the process up to the step of placing the protective concrete D inside the precast concrete formwork C is defined as one cycle, and thereafter, the same cycle is repeated and the erection work is sequentially advanced.

  By the way, in general, construction to construct a civil structure with a slope using soil cement as a rising material is called a rising construction, and a civil structure with a slope using CSG as a rising material. The construction of building is called placing construction, but here it is collectively called uplifting construction.

The slope finishing compaction work in the above erection work is done by bulging and leveling the erection material with bulldozer B, and then compacting it with a flat plate or a “shaped” vibration plate to finish the slope. As can be easily estimated from FIG. 7, the more uplifting material moves downward from the slope as the uniform slope is finished at the time of leveling with the bulldozer B and compaction with the vibration plate or the like. There is an inconvenience of spilling and it is difficult to take measures against it.
The problem is that, especially, the uplifting material is so-called CSG or soil cement, and the spilled up uplifting material E becomes industrial waste and requires a large amount of industrial waste treatment. This is a huge burden. In addition, the cleaning work of the spilled uplifted material E is not only dependent on the manual work because of the presence of the precast formwork C, but also the cleaning work in a non-free and cramped posture is performed for a long time. However, there is a problem that the progress of the process and the shortening of the construction period are serious obstacles and the burden of labor costs is also large, which has a great adverse effect on the whole of the erection work and the slope finishing compaction work.

Conventionally, as a prior art aiming at solving the above problems, for example, in Patent Document 1 below, a frame having a square cross section (square pipe shape) is installed in two steps in a stepped manner on the shoulder, Fill the hollow part of the frame with water for adjusting the weight, weigh it, and then spread and compact the upright material on the inside of the frame, and then lift the frame after completion In addition, a construction method for re-installing in the upper stage is disclosed. According to this construction method, since the frame is placed on the shoulder to make the weir, there is little possibility that the rising material will collapse or spill.
However, the finished shape of the shoulder and slope is inevitable to be stepped. Since the slope is a straight slope inclined by a certain angle in design, the amount of biting of the protective concrete is increased by the stepped shape, which is uneconomical. In addition, each time the construction process progresses, a square (square pipe shape) frame is repositioned over the shoulder, and each time it is filled with water for adjusting the weight, the rising and laying of the rising material After the compaction is completed, the process of draining and lightening the water, lifting the frame, and re-installing the upper part is repeated, so re-loading work, water supply and drainage time, and water treatment costs become a heavy burden. . There is also a problem that the amount of bite of concrete is large because it is an inclined straight line by design.

In the shoulder-shoulder construction method described in Patent Document 2 below, the erected material is biased to the inner side rather than the shoulder and is leveled. Then, the end of the sloped material on the slope side is sandwiched and held by a bucket-shaped shoulder forming device attached to the tip of an arm of a traveling construction machine such as a backhoe, and horizontally moved to a skid state so that it does not spill. The procedure is to transfer to the shoulder area and form as a shoulder wall. The shoulder-shoulder forming apparatus has a configuration in which a slope-side plate made of iron plate and a vertical plate are combined in a square shape when viewed from the front, and is used by being mounted on a vibration compactor attached to the tip of an arm such as a backhoe.
It is explained that the embankment material sandwiched by this shoulder forming device is already molded at the stage of sandwiching and is compacted by applying vibration with a vibration compactor as it is, so that a so-called bank-like bank can be formed. Has been. After forming the bank-like levee body, the embossed material is further bulged and compacted in the recesses that have been generated by moving the end of the erected material with the shoulder-shoulder forming device, and the lift component This process is completed. Hereinafter, it is recognized as a construction method in which the same process is repeated to advance the erection work and the slope finish.
Certainly, it is a construction method that has a certain reason, but as a limit of the technology for maneuvering traveling construction machines such as backhoes and their arms, the prosthetic material is sandwiched by the shoulder-shoulder forming device, and the skid is slipped as it is The position movement error when moving horizontally to the shoulder area, and the compaction stage where vibration is applied by the vibration compactor on the shoulder area, prevents the spilled material from spilling more or less from the slope. I ca n’t. In addition, it is considered that there will be problems with the finishing accuracy and quality of the slope formed as a bank-like bank on the shoulder.

The method of shoulder compaction described in the following Patent Document 3 is a “hoop” that is equivalent to the shape (angle) of the shoulder at the tip of the arm of the backhoe, with the base plate (rolling plate) and the vibration plate portion being the same. A special vibration plate tool combined with the shape is attached as an attachment, and the rising material piled up on the shoulder of the embankment is pressed against the shoulder shape (angle) with the above-mentioned special vibration plate and tightened by the backhoe hydraulic pressure It is described as a hardened configuration.
Therefore, it is not possible to prevent the spilled material from spilling out from the slope at the stage of depositing the swelling material on the shoulder and at the time of compacting the swelling by the special vibration plate tool.

Moreover, the cleaning work of the embankment material 8 spilled downward from the slope 6 can be omitted at all, or can be reduced to a remarkably simple work, and the construction period can be shortened and labor costs can be saved.

Below, based on the illustrated embodiment, the self-propelled construction machine for the slope finishing compaction method according to the present invention and the slope finishing compaction method using the self-propelled construction machine will be described.
FIG. 1 shows a self-propelled construction machine (hereinafter sometimes referred to simply as a construction machine) 10 for a slope finishing compaction method according to the present invention. This is an overview of the implementation of the slope finish compaction method.
As shown in FIGS. 2 and 3, the construction machine 10 has a cross-sectional shape that coincides with the slope 6 and the top edge 7 of the bank-like bank body 15 (see FIG. 4D, etc.) formed on the slope. A method of forming a limited space 11 between the fixed mold 2 and the movable mold 3 which is disposed opposite to the fixed mold 2 and is advanced and retracted toward the fixed mold 2 by the driving means 4. A shoulder molding mold 1 and a compacting machine 5 mounted on the shoulder molding mold 1;
As shown in FIG. 2A, the fixed formwork 2 is arranged so as to coincide with the slope 6 and the top end face 7 of the bank-like dam body 15 formed on the shoulder, and the movable formwork 3 is formed as a raised material. 2B, a portion 8a of the raised material 8 spread and spread on the inner portion excluding the vicinity of the slope 6 is moved into the fixed mold 2 side by the driving means 4 and moved (advanced) by the driving means 4. As shown in Fig. 2, the bank is pulled up to the fixed mold side 2 and raised in the limited space 11, and compacted by the compacting machine 5 so as to have a fixed height (about 25 cm in this embodiment) on the shoulder. It is implemented in a configuration that forms the bank body 15 (the invention according to claim 1). Incidentally, reference numeral 12 in the drawing indicates a hollow portion.
Specifically, the construction machine 10 according to the present embodiment is configured such that the shoulder forming mold 1 having the compacting machine 5 mounted thereon is attached to the tip of an arm 9a of a traveling construction machine 9 such as a backhoe. (Invention of claim 2). The driving shoulder 4 and the compacting machine 5 are controlled not only by freely moving the shoulder-shoulder mold 1 on which the compacting machine 5 is mounted, by the operation of the crew of the cockpit of the traveling construction machine 9. Implemented in a possible configuration.

The fixed formwork 2 is made of a metal that is bent and formed into a substantially “U” shape so as to have a cross-sectional shape that coincides with the slope 6 and the top end face 7 of the bank-like bank 15 formed on the shoulder. It is carried out with a plate.
In addition, the cross-sectional shape of the fixed mold 2 is not limited to the “shape”, and the design can be appropriately changed according to the shape of the bank-like bank body 15 formed on the shoulder. The material is not limited to metal, and may be a member having sufficient rigidity necessary for compacting the rising material (CSG). Moreover, the fixed mold 2 is implemented by making the inclined portion 2a longer than the slope length of the molding (in this embodiment, about 10 to 15 cm). This is to completely prevent the rising material 8a from spilling downward from the slope 6.
Incidentally, although the fixed mold 2 according to the illustrated example has a width B (see FIG. 3) of about 1.2 m, it is of course not limited to this, depending on the performance of the slope forming mold 1 and the like. The design can be changed as appropriate.

The movable mold 3 is implemented by a metal plate which is formed by bending the cross-sectional shape into a substantially “bent” so as to have a biting portion 3a that bites in for one layer of the upright material 8 (about 25 cm). Yes.
In addition, the cross-sectional shape of the movable mold 3 is not limited to “letter shape”, and may be any shape that can move the rising material 8 to the fixed mold 2 side by one layer. . In addition, the movable mold 3 according to the illustrated example has a width B (see FIG. 3) of about 1.2 m as in the case of the fixed mold 2, but of course the present invention is not limited to this. The design can be changed as appropriate according to the size of the frame 2 and the like.
Incidentally, reference numeral 3b in FIG. 2A indicates that the movable mold 3 avoids a collision with a connecting member 13 (see FIG. 3) provided on the upper surface of the fixed mold 2 and moves toward and away from the fixed mold 2. A notch groove is shown for possible construction.

  In the present embodiment, the drive means 4 uses a hydraulic jack 4 and is installed in a balanced manner on the upper surface of the fixed mold frame 2 and the movable mold frame 3, but it is of course limited to this. Not. What is necessary is just to implement by the drive means and arrangement | positioning which can move the movable mold 3 smoothly back and forth toward the fixed mold 2 side.

As for the compacting machine 5 of the construction machine 10, in this embodiment, a plurality (four in this embodiment) of springs 5b are arranged in a well-balanced manner between the upper and lower support plates 5a and 5a so that FIG. 3 is easy to understand. A vibration generator (electric motor) 5c is provided at the center of the upper surface of the lower support plate 5a, and is fixed to the upper surface of the fixed mold 2 via a connecting member 13. The vibration generator 5c is implemented with a configuration in which an eccentric weight is rotated by an electric motor to vibrate only in the vertical direction. Incidentally, reference numeral 5d in the figure indicates an attachment member to the tip of the arm 9a of the traveling construction machine 9, and reference numeral 16 indicates a guide portion for restraining the movable formwork 3.
Of course, the structure of the compacting machine 5 is not limited to this, and the upright material 8a taken into the limited space 11 formed by the shoulder molding mold 1 can be compacted to an appropriate hardness. Any compacting machine that can be used (for example, a tamper for rolling) may be used.

Thus, the self-propelled construction machine 10 for the slope finishing compaction method according to the present invention is a bank that forms the fixed mold 2 of the shoulder molding mold 1 on the shoulder as shown in FIG. 2A. When the ridge body 15 is aligned with the slope 6 and the top end face 7, the biting portion 3a of the movable mold 3 is further divided into a raised material 8 spread on the inner side except the vicinity of the slope 6 and leveled. (For example, about 25 cm)
In this state, when the movable mold 3 is advanced toward the fixed mold 2 by the driving means (hydraulic jack) 4, the rising material 8 existing in the limited space 11 formed by the shoulder mold 1 is formed. As shown in FIG. 2B, the part 8 a is attracted to the fixed mold side 2 and raised in the limited space 11 as shown in FIG. 2B. The rising material 8a does not spill downward due to the damming effect of the fixed mold 2.
In this state, when the compacting machine 5 mounted on the shoulder-shoulder mold 1 is started, the upright material 8a raised in the limited space 11 is compacted to an appropriate hardness and has a certain height. A bank-like bank body 15 is formed.

Next, the slope finishing compaction method implemented using the self-propelled construction machine 10 for the slope finishing compaction method having the above-described configuration will be described with reference to FIGS.
Incidentally, FIGS. 4A to E are elevation views showing the step of laying and leveling the first layer of rising material (CSG) 8 by the construction machine 10, and FIGS. FIGS. 6A to 6C are elevation views showing a step of spreading and leveling the second layer of the rising material 8, and FIGS. 6A to 6C step by step the step of spreading and leveling the second layer of the rising material 8. It is the shown top view.

  As shown in FIG. 4A, a raised material (CSG) 8 in which cement is added to the locally generated material and mixed on the finished surface 14 is layered with a bulldozer or the like to a thickness of about 25 cm per layer, for example. The In order to prevent the rising material 8 from spilling down when laying the floor, it is applied to an inner portion having a required interval S (about 30 cm in this embodiment) S from the slope 6 to be molded. The spacing S can be appropriately changed in design according to the layer thickness of the laying material 8 to be spread or the working environment such as the temperature.

  As shown in FIG. 4B, the shoulder forming mold 1 of the construction machine 10 is fixed so that the fixed mold 2 coincides with the slope 6 and the top edge 7 of the bank-like dam body 15 formed on the shoulder. Install in. Then, in the movable mold 3 that faces the fixed mold 2, the biting portion 3 a bites into the upright material 8 by one layer (about 25 cm). Incidentally, when installing the shoulder forming mold 1, the movable mold 3 is set in a state of being retracted in advance by extending the hydraulic jack 4 with respect to the fixed mold 2.

As shown in FIG. 4C, the hydraulic jack 4 is contracted, and the movable mold 3 is advanced toward the fixed mold 2 side.
If it does so, the rising material 8a which exists in the limited space 11 which the shoulder forming mold 1 forms among the rising materials 8 will be drawn near to the fixed mold 2 side. The rising material 8a does not spill downward due to the damming effect of the fixed mold 2.
After confirming the state in which the rising material 8a is raised in the limited space 11 (in the present embodiment, the state is filled with no gaps), the compacting machine 5 of the construction machine 10 is started and the limited space 11 is activated. The embankment material 8a in the inside is compacted to an appropriate hardness, and a bank-like bank body 15 having a certain height and having a slope 6 and a top end face 7 is formed on the shoulder.

As shown in FIG. 4D, after the bank-like bank body 15 is formed, the shoulder forming mold 1 of the construction machine 10 is moved to the next construction site.
The above steps are sequentially performed in the longitudinal direction (width direction) of the slope 6 in accordance with the traveling of the construction machine 10 to continuously form the bank-like dam body 15 on the shoulder, and the raised material 8a attracted. As shown in FIG. 4E, a work for raising the leveling material 8 and spreading it to a thickness of one layer is carried out with a bulldozer or the like, as shown in FIG. 4E. The step of spreading the leveling material (CSG) 8 of the first layer of the part is finished.
Subsequently, also on the right side portion of FIG. 7, the above-described steps of FIGS. 4A to E are performed, and thus the entire surface of the first layer of the rising material 8 is spread and leveled.

  In addition, the operation | work which spreads the embankment material 8 on the trace T of the embankment material 8a which concerns on FIG. 4E makes a bulldozer track the back of the method shoulder shaping | molding form 1 of the construction machine 10 which concerns on this invention, and a bank-like embankment. It can be performed every time the body 15 is formed, or can be performed after the bank-like bank body 15 is formed in a certain length in the longitudinal direction of the slope.

  As described above, according to the slope finishing compaction method according to the first layer, as shown in FIG. 4A, the work of spreading and leveling the first layer of the rising material 8 is the slope 6 to be molded. Therefore, there is no possibility that the rising material 8 spills downward from the slope 6 because the inner portion is spaced from the inner surface at a required interval (about 30 cm in this embodiment). In addition, as shown in FIG. 4C, the inclined portion 2a longer than the slope length is also formed in the work of drawing the banking material 15a by the movable mold 3 to the fixed mold 2 side to form the bank-like bank body 15. Due to the damming effect of the fixed mold 2 having the above, there is no possibility that the rising material 8a spills downward from the slope 6. Even after the bank-like levee body 15 is formed and the embankment material 8 is spread on the inner side of the bank-like levee body 15, the embankment material 8a is naturally sloped by the damming effect of the bank-like dam body 15. There is no risk of spilling downward from 6.

As described above, after finishing the leveling work of the first layer of the rising material (CSG) 8 through the steps of FIGS. 4A to 4E, as shown in FIG. On the upper surface of the upright material 8, the upright material 8 is spread in layers with a bulldozer or the like to a thickness of about 25 cm per layer. In order to prevent the rising material 8 from spilling downward when leveling, it is necessary to construct the inner portion at a required interval (about 30 cm in this embodiment) S from the slope 6 to be molded. It is the same as the work of the layer.
Incidentally, the parts indicated by reference signs a to d in FIG. 5A correspond to the parts indicated by reference signs a to d in FIGS. The symbol a indicates the slope of the first layer. The symbol b indicates the top end face of the first bank bank-like bank. Reference sign c indicates the slope of the second layer. Reference sign d indicates the top end face of the second layer of the raised material 8.

  Next, as shown in FIGS. 5B and 6A, the fixed mold 2 molds the shoulder forming mold 1 of the construction machine 10 as shown in FIGS. As shown in FIGS. 5C and 6B, the movable mold 3 is moved to the fixed mold 2 side by contracting the hydraulic jack 4 as shown in FIGS. 5C and 6B. Advance (see paragraphs [0022] and [0023] for details).

Subsequently, as shown in FIGS. 5D and 6C, after the bank-like bank body 15 is formed, the shoulder forming mold 1 of the construction machine 10 is moved to the next construction site.
The above steps are sequentially performed in the longitudinal direction (width direction) of the slope 6 in accordance with the traveling of the construction machine 10 to continuously form the bank-like dam body 15 on the shoulder, and the raised material 8a attracted. As shown in FIG. 5E, the work for leveling up the laying material 8 and spreading it to a thickness equivalent to the portion where the upper surface of the staking material 8 of the first layer of the trace T is exposed is a bulldozer, etc. For example, the step of laying and leveling the second layer of rising material (CSG) 8 on the left side of FIG. 7 is completed.
Subsequently, the above-described steps of FIGS. 5A to 5E are also performed on the right side portion of FIG. 7, and thus the entire surface of the second layer of the rising material 8 is spread and leveled.

In addition, the operation | work which spreads the embankment material 8 on the trace T of the embankment material 8a which concerns on FIG. 5E is the shoulder-shoulder mold of the construction machine 10 which concerns on this invention similarly to the operation | work concerning the above-mentioned 1st layer. It can be performed each time the bank-like levee body 15 is formed by following the bulldozer behind the frame 1, or can be performed after the bank-like dam body 15 is formed in a certain length in the longitudinal direction of the slope.
Incidentally, the portions indicated by reference signs ej in FIG. 5D correspond to the portions indicated by reference signs ej in FIGS. The symbol e indicates the slope of the first layer. Reference symbol f indicates the slope of the bank-like bank body 15 in the second layer. The symbol g indicates the top end face of the bank-like bank body 15 in the second layer. The symbol h indicates the slope of the bank-like bank in the second layer. The symbol i indicates the exposed top end surface of the first layer. Reference symbol j indicates the top end face of the second layer of the raised material 8.

  Thus, according to the slope finishing compaction method according to the second layer, since the same method as the slope finishing compaction method of the first layer shown in FIGS. There is no possibility that 8a spills downward from the slope 6.

Hereinafter, the work process after the third layer (for example, refer to FIG. 1) is also performed through the same process as the first layer and the second layer described above. There is no risk of spilling.
In short, according to the slope finishing compaction method according to the present invention, the bank-like levee body 15 having an appropriate hardness and having a certain height can be obtained without spilling the rising material 8 (8a) from the slope 6 at all. It can be formed continuously in the longitudinal direction of the slope 6.

  For example, quoting the work process based on FIG. 7 related to the above [Background Art], the process of raising and leveling with bulldozer B to a thickness of about 25 cm per layer is repeated for three layers, and thereafter with a vibrating roller or the like. According to the present invention, when the lower layer lift of the protective concrete D is formed by repeating the process of compacting the three layers (75 cm) together, the rising material 8 (E) is completely spilled from the slope 6. Can be implemented without any problem. In addition, when the precast concrete formwork C is installed along the slope of the lower layer lift, and then the upper layer lift portion is constructed by repeating the swelling, leveling and compaction process for three layers again, the present invention According to the above, the embossing material 8 (E) can be carried out without spilling off the slope 6 at all.

Although the present invention has been described above based on the illustrated embodiment, it is needless to say that the present invention is not limited to the illustrated embodiment. It goes without saying that the present invention can be implemented in various ways, including design changes made by those skilled in the art, without departing from the scope and spirit of the present invention.
For example, in the present embodiment, the erection work (casting work) using CSG as the erection material 8 has been described, but the present invention is not limited to this, and the same applies to the erection work using soil cement as the erection material 8. Can be implemented.
Further, in this embodiment, the rising material 8 is compacted for each layer (height of about 25 cm), but the present invention is not limited to this. By using a large compacting machine 5, it is possible to draw the upright material 8 at a time and compact it after three layers (a height of about 75 cm) are spread and leveled.
Furthermore, when the properties of the staking material 8 are slightly soft and overflow from both sides of the fixed mold 2 due to the working environment or the like, the width B of the fixed mold 2 is slightly longer than the width of the movable mold 3. For example, it may be carried out appropriately, or the tip portion of the biting portion 3a of the movable mold 3 may be formed in a tapered shape (wedge shape) so that the biting material 8 is easily bited.
