[Technical field]

[0001] The present invention relates to an apparatus and method for inserting a joint plate into a construction object such as a dam embankment. [Background technology]

[0002] In construction of embankment bodies for concrete dams and CSG dams, so-called joint cutting work is often carried out to prevent problems caused by stresses that arise with the expansion and contraction of the embankment body. In this joint cutting work, joints (seams) are formed by inserting multiple joint plates (plate-shaped joint materials) into predetermined positions in the embankment body. One example of a device used for this joint cutting work is disclosed in Patent Document 1 as a concrete joint cutting machine. [Prior art documents] [Patent documents]

[0010] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Fig. 1 is a diagram showing a schematic configuration of a joint plate insertion device in one embodiment of the present invention. Fig. 2(a) is a plan view of a stocker and a guide unit. Fig. 2(b) is a side view of the stocker and the guide unit. Fig. 2(c) is a cross-sectional view taken along line AA of Fig. 2(a).

[0011] Here, in this embodiment, the embankment of a dam is taken as an example of the "construction object" of the present invention, but the "construction object" of the present invention is not limited to the embankment of a dam. In addition, in the following embodiment, the embankment is described as being made of CSG, but it may be made of, for example, ultra-hard concrete with a slump value of approximately zero. CSG (Cemented Sand and Gravel) and concrete harden over time after cement and solidification material are mixed.

[0012] In this embodiment, a joint plate insertion device 10 is used when constructing the embankment body 1. Here, the CSG constituting the embankment body 1 is a cement-based material made by mixing cement and water with rock-like materials such as sand and stones. The CSG constituting the embankment body 1 has a hardness such that the joint plate insertion device 10 can run (move) on its upper surface 2 when cutting joints.

[0013] The joint plate insertion device 10 is a device that inserts a joint plate 5 (see FIGS. 3 to 8 described later) into the embankment body 1. The joint plate insertion device 10 includes a base machine 20, an arm unit 30, a stocker 40, and an insertion unit 60.

[0014] The base machine 20 has a vehicle body 21 capable of self-propelling on the upper surface 2 of the bank body 1, and a rotating body 22 mounted on the vehicle body 21 so as to be capable of horizontally rotating.

[0015] The vehicle body 21 has a vehicle body 23 and caterpillar tracks 24. The caterpillar tracks 24 are provided on both sides of the vehicle body 23, and are driven to rotate by a drive unit (not shown) built into the vehicle body 23. Therefore, the vehicle body 21 travels on the upper surface 2 of the embankment 1 by rotating the caterpillar tracks 24.

[0016] The rotating body 22 is installed on the vehicle body 23. A rotating shaft 25 is connected to the lower part of the rotating body 22, and the rotating shaft 25 is driven to rotate by a drive unit (not shown) built into the vehicle body 23. The rotating body 22 rotates horizontally by rotating the rotating shaft 25.

[0017] A control room 26 is provided at the front of the rotating body 22. The control room 26 is equipped with various operating devices for controlling the overall operation of the joint plate insertion device 10. An operator can operate the joint plate insertion device 10 by operating the operating devices in the control room 26.

[0018] The arm 30 is bent in a dogleg shape, and its base end is pivoted to the front of the rotating body 22 (to the side of the cockpit 26) via a horizontally extending pivot shaft (not shown). The pair of jacks 32 are attached so that their upper ends sandwich the center of the arm 30 (the bent part of the dogleg shape described above) from both left and right sides, while their lower ends are attached to the front of the rotating body 22 (to the side of the cockpit 26). Thus, by extending and retracting the jacks 32, the arm 30 swings up and down relative to the rotating body 22 via the pivot shaft at its base end. The jacks 32 are, for example, hydraulic jacks.

[0019] A bracket 61 of the insertion part 60 is attached to the tip 33 of the arm 30 via a pivot shaft 34 extending horizontally. A jack 35 is disposed above the arm 30. One end of the jack 35 is attached to the upper part of the center of the arm 30 (the bent part in the above-mentioned "L" shape), while the other end is attached to the bracket 61 of the insertion part 60 via a pivot shaft 36 extending horizontally. Therefore, by extending and retracting the jack 35, the insertion part 60 swings relative to the arm 30 via the pivot shaft 34. The jack 35 is, for example, a hydraulic jack.

[0020] The insertion section 60 comprises the aforementioned bracket 61, a telescopic tube 62 attached to the bracket 61 and capable of extending and retracting in the vertical direction, a swivel device 63 attached to the lower end of the telescopic tube 62, a gate-shaped frame 64 attached to the swiveled section side of the swivel device 63, a vibration excitation device 66 attached to the gate-shaped frame 64 via an elastic body 65 such as rubber or a spring, and a blade (joint cutter) 67 attached to the vibration excitation device 66.

[0021] The telescopic tube 62 has an outer tube 62a, an inner tube 62b attached to the outer tube 62a so as to be movable up and down, and a hydraulic cylinder (not shown) for raising and lowering the inner tube 62b relative to the outer tube 62a. In this embodiment, the turning device 63 is configured so that the lower turned part can be turned by hand, but instead, a remote-controlled turning device using a turning motor or the like may be used.

[0022] The vibration exciter 66 has a motor 68 that rotates two eccentric weights (not shown). The upper end of a blade 67 is fixed to the lower end of the vibration exciter 66. The vibration exciter 66 vibrates the blade 67. The blade 67 is, for example, a rectangular plate made of steel.

[0023] The stocker 40 is provided on the bottom surface 28 at the front of the rotating body 22, and is capable of stacking and loading a plurality of joint plates 5. The stocker 40 is configured so that, for example, several tens to a hundred joint plates 5 can be stacked one on top of the other.

[0024] The joint plate 5 is rectangular and made of metal. The joint plate 5 is made of, for example, a zinc thin steel plate. The thickness of the joint plate 5 is, for example, 1 mm or less. The joint plate 5 is, for example, square with each side measuring about 1 m.

[0025] The stocker 40 is, for example, a rectangular box shape with an open top. In this embodiment, a rear wall 41, a left wall 42, and a right wall 43 of the stocker 40 rise from a bottom surface 44, and the front portion thereof is open and communicates with a receiving portion 45a of a guide portion 45.

[0026] The guide portion 45 is composed of a receiving portion 45a located in front of the stocker 40 and communicating with the stocker 40, and a cylindrical portion 45b having a rectangular cross section that extends downward from the lower end of the receiving portion 45a.

[0027] The receiving portion 45a has a left wall extension portion 42e extending forward from the front end of the left wall 42 of the stocker 40, a right wall extension portion 43e extending forward from the front end of the right wall 43, and a front wall 46 whose both ends are connected to the front end of the left wall extension portion 42e and the front end of the right wall extension portion 43e.

[0028] In this embodiment, the front wall 46, the rear wall 41, the left wall 42, the left wall extension 42e, the right wall 43, and the right wall extension 43e form a peripheral wall 48 that is rectangular in top view. In this embodiment, an opening of the peripheral wall 48 that is surrounded by the lower end of the rear wall 41, the lower end of the left wall 42, and the lower end of the right wall 43 is closed by the bottom surface 44. An opening of the peripheral wall 48 that is surrounded by the lower end of the front wall 46, the lower end of the left wall extension 42e, and the lower end of the right wall extension 43e communicates with an upper surface opening of the tube portion 45b.

[0029] The cylindrical portion 45b has a rectangular cross section and extends in the vertical direction, with its top and bottom surfaces each being open. The upper end of the cylindrical portion 45b is connected to the lower end of the front wall 46, the lower end of the left wall extension portion 42e, the lower end of the right wall extension portion 43e, and the front end of the bottom surface 44. The height (vertical length) of the cylindrical portion 45b is preset so that the lower end of the cylindrical portion 45b does not rub against the upper surface 2 of the embankment body 1 when the joint plate insertion device 10 runs along a sloped portion of the upper surface 2 of the embankment body 1.

[0030] The shapes of the stocker 40 and the guide portion 45 are not limited to those described above.

[0031] Next, the discharge section 50, which discharges multiple joint boards 5 stacked vertically in the stocker 40 one by one from the stocker 40 to the receiving section 45a of the guide section 45 (i.e., outside the stocker 40), will be described with reference to Figures 3 and 4.

[0032] 3 and 4 show a first example and a second example of the discharge portion 50. FIG.

[0033] The discharge section 50 is provided on at least one of the revolving body 22 and the stocker 40. Here, the joint plate insertion device 10 includes a supply section 70 capable of supplying a plurality of joint plates 5 stacked vertically in the stocker 40 one by one onto the upper surface 2 of the embankment body 1, and this supply section 70 includes the discharge section 50 and a guide section 45.

[0034] 3(A) and 3(B), a motorized, extendable and swingable arm 51 sends (discharges) the joint boards 5 one by one from the stocker 40 to the receiving section 45a of the guide section 45. Here, by providing a non-slip material 52 made of rubber or the like on the tip of the arm 51 that contacts the joint board 5, the joint boards 5 can be smoothly discharged one by one from the stocker 40.

[0035] 4A and 4B, a roller 53 made of rubber, for example, is rotated in the direction of the arrow in the figure while being in contact with the upper surface of the joint board 5, thereby sending (discharging) the joint boards 5 one by one from the stocker 40 to the receiving part 45a of the guide part 45. In this example, instead of the roller 53, a small belt conveyor may be used to send the joint boards 5 one by one from the stocker 40 to the receiving part 45a of the guide part 45. Even in this case, by providing a non-slip member made of rubber or the like on the part of the belt conveyor that comes into contact with the joint board 5, the joint boards 5 can be smoothly discharged one by one from the stocker 40.

[0036] Although not shown in the figures, in a third example of the discharge unit 50, the discharge unit 50 can be configured to include a gripping unit that grips the joint boards 5 one by one while discharging them from the stocker 40 to the receiving unit 45a of the guide unit 45. In a fourth example of the discharge unit 50, the discharge unit 50 can be configured to include an air-type suction unit that sucks in the joint boards 5 one by one while discharging them from the stocker 40 to the receiving unit 45a of the guide unit 45.

[0037] Furthermore, each of the examples of the discharge section 50 described above can be configured so that the joint boards 5 can be discharged one by one from the stocker 40 to the receiving section 45a of the guide section 45 (i.e., outside the stocker 40) by an operator pressing an operating switch (not shown) provided in the cockpit 26.

[0038] FIG. 5 is a diagram for explaining a method for supplying a plurality of joint boards 5 stacked vertically in a stocker 40 one by one from the stocker 40 onto the upper surface 2 of the bank body 1. As shown in FIG.

[0039] As shown by the white arrow in FIG. 5, the joint boards 5 stacked vertically in the stocker 40 are first discharged from the stocker 40 substantially horizontally toward the receiving section 45a of the guide section 45 by the operation of the discharge section 50. After hitting the front wall 46 of the receiving section 45a of the guide section 45, the discharged joint boards 5 pass through the inside of the tube section 45b and fall (free fall) onto the upper surface 2 of the bank body 1. Here, the supply section 70 realizes the function of supplying the multiple joint boards 5 stacked vertically in the stocker 40 one by one onto the upper surface 2 of the bank body 1. In addition, the guide section 45 realizes the function of guiding the joint boards 5 discharged from the stocker 40 by the discharge section 50 toward the upper surface 2 of the bank body 1. In addition, the guide section 45 can also realize the function of correcting the direction and posture of the joint boards 5 discharged from the stocker 40 by the discharge section 50.

[0040] Next, the joint cutting work using the joint plate insertion device 10 will be described with reference to Fig. 6 to Fig. 8. Fig. 6 to Fig. 8 show a method for inserting the joint plate 5 into the embankment body 1. In the following description, with respect to the multiple joint plates 5 placed in order on the upper surface 2 of the embankment body 1, the reference number for the nth joint plate 5 placed is "5-n" (n is a natural number).

[0041] In the method of inserting the joint board 5, first, as shown in Fig. 6(A), the supply unit 70 (the discharge unit 50 and the guide unit 45) is used to place the joint board 5-1 on the upper surface 2 of the embankment body 1 (placement step). In this step, the joint board 5-1 is placed on the upper surface 2 of the embankment body 1 between the stocker 40 and the insertion unit 60.

[0042] Thereafter, as shown in Figures 6(a) and (c), the base machine 20 is retracted and the joint board 5 is placed on the upper surface 2 of the embankment body 1 using the supply unit 70, and the insertion unit 60 is positioned directly above the joint board 5-1, as shown in Figure 6(c). This process of retracting the base machine 20 corresponds to the "moving process" of the present invention. In other words, in this process, the base machine 20 is moved so that the insertion unit 60 is positioned directly above the joint board 5-1. In this embodiment, the gap between adjacent joint boards 5 is, for example, about 10 cm.

[0043] 7(d), the joint board 5-1 is inserted to a predetermined depth into the embankment body 1 while being bent by the insertion part 60 (insertion process). During this insertion, the blade 67 is vibrated by the vibration device 66, and the telescopic tube 62 is extended downward to lower the blade 67, thereby bending the joint board 5-1 with the blade 67 and inserting it into the embankment body 1. The bent joint board 5-1 is in a so-called double-folded state, but it does not have to be folded evenly in half.

[0044] Next, as shown in FIG. 7(e), the telescopic tube 62 is contracted to raise the blade 67 (pulling up process).

[0045] Next, as shown in FIG. 7(f), the base machine 20 is moved backward so that the insertion portion 60 is positioned directly above the joint board 5-2 (moving step).

[0046] Next, as shown in FIG. 8(g), the joint board 5-4 is placed on the upper surface 2 of the bank body 1 using the supply unit 70 (placement step).

[0047] Next, as shown in Figure 8(K), 2 The joint plate 5-2 is inserted into the embankment body 1 to a predetermined depth while being bent by the insertion part 60 (insertion process). During this insertion, the blade 67 is vibrated by the vibration device 66, and the telescopic tube 62 is extended downward to lower the blade 67, so that the joint plate 5-2 is inserted into the embankment body 1 while being bent by the blade 67. The bent joint plate 5-2 is also in a so-called two-fold state, like the above-mentioned joint plate 5-1, but it does not have to be folded evenly in half.

[0048] Thereafter, the aforementioned lifting, moving, placing, and inserting steps are repeated in sequence to insert a plurality of joint plates 5 into the embankment body 1 (see FIG. 8(K)). Here, FIG. 8(K) shows a state in which ten joint plates 5 (5-1 to 5-10) have been inserted into the embankment body 1, but it goes without saying that the number of joint plates 5 inserted into the embankment body 1 is not limited to this. For example, at a joint cutting location with a construction length of 100 m, approximately 100 joint plates 5 can be inserted into the embankment body 1.

[0049] In this embodiment, the inserting step is performed after the placing step, but the inserting step may be performed prior to the placing step. Alternatively, at least a part of the placing step and at least a part of the inserting step may be performed simultaneously.

[0050] In conventional joint cutting work, for example, when using a joint cutting machine as disclosed in Patent Document 1, each time a joint plate was inserted into the embankment body, it was necessary to attach a joint plate having a J-shaped cross section to the joint cutting plate that constitutes the joint cutting machine, and this attachment work was performed manually by a worker.

[0051] In this regard, according to the present embodiment, this mounting work can be omitted, and therefore the manual work required by the worker can be reduced.

[0052] According to this embodiment, the joint plate insertion device 10 comprises a base machine 20 having a vehicle body 21 capable of running on the upper surface 2 of the construction object (e.g., a bank body 1) and a rotating body 22 rotatably mounted on the vehicle body 21, an arm 30 whose base end is pivoted to the rotating body 22 and capable of swinging, a stocker 40 mounted on the rotating body 22 and capable of loading multiple joint plates 5, a supply unit 70 mounted on the rotating body 22 and / or the stocker 40 and capable of supplying the multiple joint plates 5 loaded on the stocker 40 one by one onto the upper surface 2 of the construction object (e.g., the bank body 1), and an insertion unit 60 mounted on the tip 33 of the arm 30 and capable of inserting the joint plate 5 supplied onto the upper surface 2 of the construction object (e.g., the bank body 1) into the construction object (e.g., the bank body 1). Therefore, the work of attaching the joint plate 5 to the blade 67 can be omitted, and the efficiency of the joint cutting work for the construction object (for example, the embankment body 1) can be improved.

[0053] According to this embodiment, the supply unit 70 includes a discharge unit 50 that discharges the plurality of joint boards 5 loaded in the stocker 40 one by one out of the stocker 40, and a guide unit 45 that guides the joint boards 5 discharged by the discharge unit 50 toward the upper surface 2 of the construction object (e.g., the embankment 1). This allows the joint boards 5 to be easily and accurately supplied to predetermined positions on the upper surface 2 of the construction object (e.g., the embankment 1).

[0054] Also, according to the present embodiment, a method of inserting the joint board 5 into a construction object (for example, the embankment 1) using the joint board inserting device 10 includes a placing step of placing the joint board 5 on the upper surface 2 of the construction object (for example, the embankment 1) using the supply unit 70, a moving step of moving the base machine 20 so that the insertion part 60 is positioned directly above the placed joint board 5, and an insertion step of inserting the placed joint board 5 into the construction object (for example, the embankment 1) while bending it with the insertion part 60. Therefore, the work of attaching the joint board 5 to the blade 67 can be omitted, and the efficiency of the joint cutting work for the construction object (for example, the embankment 1) can be improved.

[0055] Also, according to the present embodiment, in the above-described placing step, the joint board 5 is placed on the upper surface 2 of the construction object (for example, the embankment 1) between the stocker 40 and the insertion part 60. Thereby, the insertion part 60 can be easily positioned directly above the joint board 5 only by retracting the base machine 20 in the above-described moving step.

[0056] Also, according to the present embodiment, a method of inserting the joint board 5 into a construction object (for example, the embankment 1) includes a placing step of placing at least one joint board 5 on the upper surface 2 of the construction object (for example, the embankment 1), and an insertion step of inserting the placed joint board 5 into the construction object (for example, the embankment 1) while bending it. Therefore, the work of attaching the joint board 5 to the blade 67 can be omitted, and the efficiency of the joint cutting work for the construction object (for example, the embankment 1) can be improved.

[0057] In addition, in the present embodiment, the embankment of a dam is described as an example of the "construction object" of the present invention. However, the "construction object" of the present invention is not limited to the embankment of a dam, and may be, for example, an embankment such as a coastal or river levee.
