Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in the joint cutting work disclosed in Patent Document 1, every time one joint board is inserted into the embankment, it is necessary to attach a joint board having a J-shaped cross section to the joint cutting board constituting the concrete joint cutter (see, for example, paragraphs 0024 and 0033 of Patent Document 1), so this attachment work has been troublesome.

[0005] In view of such a situation, an object of the present invention is to improve the efficiency of joint cutting work for a construction object such as a dam embankment.

Means for Solving the Problems

[0006] Therefore, one aspect of the present invention is a method for supplying a joint board to be inserted into a construction object on the upper surface of the construction object, comprising: In the above method, an apparatus is used which includes a vehicle body capable of traveling on the upper surface of the object to be constructed, a stocker arranged on the vehicle body and capable of loading a plurality of perforated plates, and a supply unit capable of supplying the plurality of perforated plates loaded on the stocker one by one onto the upper surface of the object to be constructed. The above method includes placing a perforated plate on the upper surface of the object to be constructed using the supply unit prior to inserting the perforated plate into the object to be constructed.

[0007] Another aspect of the present invention is an apparatus for supplying a perforated plate to be inserted into an object to be constructed onto the upper surface of the object to be constructed, the apparatus comprising: a vehicle body capable of traveling on the upper surface of the object to be constructed; a stocker arranged on the vehicle body and capable of loading a plurality of perforated plates; a supply unit capable of supplying the plurality of perforated plates loaded on the stocker one by one onto the upper surface of the object to be constructed; and is provided with.

Advantages of the Invention

[0008] According to the present invention, since the perforated plate placed on the upper surface of the object to be constructed is inserted into the object to be constructed, the operation of attaching the perforated plate to the joint cutting plate can be omitted. Therefore, the efficiency of the joint cutting operation for the object to be constructed can be improved.

Embodiments for Carrying Out the Invention

[0010] Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a diagram showing a schematic configuration of a joint board insertion device according to an embodiment of the present invention. FIG. 2(A) is a plan view of a stocker and a guide part. FIG. 2(I) is a side view of the stocker and the guide part. FIG. 2(U) is a cross-sectional view taken along line A-A of FIG. 2(A).

[0011] Here, in the present embodiment, the dam embankment is taken as an example of the "object to be constructed" of the present invention for explanation, but the "object to be constructed" of the present invention is not limited to the dam embankment. Further, in the present embodiment, the embankment is assumed to be made of CSG for the following description, but alternatively, for example, it may be made of superplasticized concrete with a slump value of substantially zero. CSG (Cemented Sand and Gravel) and concrete harden over time after cement and solidifying agents are mixed.

[0012] In the present embodiment, when constructing the embankment 1, the joint board insertion device 10 is used. Here, the CSG constituting the embankment 1 is a cementitious material obtained by mixing cement and water with a rocky material such as sand or stone, for example. The CSG constituting the embankment 1 has a hardness such that the joint board insertion device 10 can travel (move) on the upper surface 2 thereof during joint cutting.

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

[0014] The base machine 20 has a vehicle body 21 capable of self-running on the upper surface 2 of the embankment 1 and a swivel body 22 provided on the vehicle body 21 so as to be horizontally rotatable.

[0015] The vehicle body 21 has a vehicle body main body 23 and endless tracks 24. The endless tracks 24 are provided on both side portions of the vehicle body main body 23 and are driven by a drive device (not shown) built in the vehicle body main body 23 to rotate. Accordingly, the vehicle body 21 travels on the upper surface 2 of the dike body 1 by rotating the endless tracks 24.

[0016] The slewing body 22 is installed on the vehicle body main body 23. A slewing shaft 25 is connected to the lower portion of the slewing body 22, and the slewing shaft 25 is driven by a drive device (not shown) built in the vehicle body main body 23 to rotate. The slewing body 22 horizontally slews by rotating the slewing shaft 25.

[0017] A cab 26 is provided at the front portion of the slewing body 22. The cab 26 is equipped with various operating instruments for controlling the overall operation of the eye floor inserting device 10. An operator can operate the eye floor inserting device 10 by operating the operating instruments in the cab 26.

[0018] The arm portion 30 is bent in a "く" shape, and its proximal end is pivotally supported at the front portion of the slewing body 22 (lateral side of the cab 26) via a pivot shaft (not shown) extending in the horizontal direction. A pair of jacks 32 are attached such that their upper ends sandwich the central portion of the arm portion 30 (the bent portion in the aforementioned "く" shape) from both left and right sides, while their lower ends are attached to the front portion of the slewing body 22 (lateral side of the cab 26). Accordingly, by extending and retracting the jacks 32, the arm portion 30 swings vertically with respect to the slewing body 22 via the pivot shaft at its proximal end. Incidentally, the jack 32 is, for example, a hydraulic jack.

[0019] At the tip 33 of the wrist 30, a bracket 61 of the insertion part 60 is attached via a pivot shaft 34 extending in the horizontal direction. Above the wrist 30, a jack 35 is arranged. One end of the jack 35 is attached to the upper part of the central part of the wrist 30 (the bent part in the aforementioned "く" shape), while the other end is attached to the bracket 61 of the insertion part 60 via a pivot shaft 36 extending in the horizontal direction. Therefore, by expanding and contracting the jack 35, the insertion part 60 swings with respect to the wrist 30 via the pivot shaft 34. Incidentally, the jack 35 is, for example, a hydraulic jack.

[0020] The insertion part 60 includes the aforementioned bracket 61, a telescopic cylinder 62 provided on the bracket 61 and capable of expanding and contracting in the vertical direction, a turning device 63 provided at the lower end of the telescopic cylinder 62, a portal frame 64 attached to the side of the part to be turned of the turning device 63, an oscillating device 66 attached to the portal frame 64 via an elastic body 65 such as rubber or a spring, and a blade (joint cutting plate) 67 attached to the oscillating device 66.

[0021] The telescopic cylinder 62 includes an outer cylinder 62a, an inner cylinder 62b that is vertically movably attached to the outer cylinder 62a, and a hydraulic cylinder (not shown) for moving the inner cylinder 62b up and down with respect to the outer cylinder 62a. In the present embodiment, the turning device 63 is configured such that the lower part to be turned can be turned manually, but instead, a remotely operated turning device using a turning motor or the like may be used.

[0022] The oscillating device 66 has a motor 68 that rotates two eccentric weights (not shown). The upper end of the blade 67 is fixed to the lower end part of the oscillating device 66. The oscillating device 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 of the front part of the swivel body 22 and can stack a plurality of joint plates 5. The stocker 40 is configured to be able to stack, for example, about several tens to one hundred joint plates 5 vertically.

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

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

[0026] The guide portion 45 includes a receiving portion 45a located in front of the stocker 40 and communicating with the stocker 40, and a cylindrical portion 45b with a rectangular cross-section extending 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 with both ends 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, a peripheral wall 48 having a rectangular shape in top view is formed by the front wall 46, the rear wall 41, the left wall 42, the left wall extension portion 42e, the right wall 43, and the right wall extension portion 43e. In this embodiment, among the peripheral wall 48, the opening 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 blocked by the bottom surface 44. Among the peripheral wall 48, the opening surrounded by the lower end of the front wall 46, the lower end of the left wall extension portion 42e, and the lower end of the right wall extension portion 43e communicates with the upper surface opening of the cylindrical portion 45b.

[0029] The cylindrical portion 45b has a rectangular cross-section and extends in the vertical direction, with its upper surface and lower surface 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 (length in the vertical direction) of the cylindrical portion 45b is preset, for example, so that the lower end of the cylindrical portion 45b does not rub against the upper surface 2 when the mesh floor inserting device 10 travels on the sloped portion of the upper surface 2 of the embankment body 1.

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

[0031] Next, a discharging unit 50 that discharges the plurality of spacer plates 5 stacked one on top of the other in the stocker 40 one by one from the stocker 40 to the receiving portion 45a of the guide portion 45 (that is, outside the stocker 40) will be described with reference to FIGS. 3 and 4.

[0032] FIGS. 3 and 4 show a first example and a second example of the discharging unit 50.

[0033] The discharging unit 50 is provided on at least one of the rotating body 22 and the stocker 40. Here, the spacer plate inserting device 10 includes a supply unit 70 that can supply the plurality of spacer plates 5 stacked one on top of the other in the stocker 40 one by one onto the upper surface 2 of the dam 1, and this supply unit 70 includes the discharging unit 50 and the guide portion 45.

[0034] In the first example of the discharging unit 50 shown in FIG. 3, as shown in FIGS. 3(A) and (B), the spacer plates 5 are sent out (discharged) one by one from the stocker 40 to the receiving portion 45a of the guide portion 45 by an electric telescopic and swingable arm 51. Here, by providing a non-slip member 52 made of rubber or the like at the tip of the arm 51 that contacts the spacer plate 5, the spacer plates 5 can be discharged well one by one from the stocker 40.

[0035] In the second example of the discharging unit 50 shown in FIG. 4, as shown in FIGS. 4(A) and (B), for example, by rotating a rubber roller 53 in the direction of the arrow in the figure while bringing it into contact with the upper surface of the spacer plate 5, the spacer plates 5 are sent out (discharged) one by one from the stocker 40 to the receiving portion 45a of the guide portion 45. Incidentally, in this example, instead of the roller 53, a small belt conveyor may be used to send out the spacer plates 5 one by one from the stocker 40 to the receiving portion 45a of the guide portion 45. Also in this case, by providing a non-slip member made of rubber or the like at the portion of the belt conveyor that contacts the spacer plate 5, the spacer plates 5 can be discharged well one by one from the stocker 40.

[0036] Although illustration is omitted, in the third example of the discharge unit 50, the discharge unit 50 may be provided with a gripping unit, and this gripping unit may be configured to discharge the eye floor plates 5 one by one from the stocker 40 to the receiving portion 45a of the guide unit 45 while gripping them. Further, in the fourth example of the discharge unit 50, the discharge unit 50 may be provided with an air suction unit, and this suction unit may be configured to discharge the eye floor plates 5 one by one from the stocker 40 to the receiving portion 45a of the guide unit 45 while sucking them.

[0037] In addition, for each of the above-described examples of the discharge unit 50, for example, by an operator pressing an operation switch (not shown) provided in the control room 26, the eye floor plates 5 can be discharged one by one from the stocker 40 to the receiving portion 45a of the guide unit 45 (that is, outside the stocker 40).

[0038] FIG. 5 is a diagram for explaining a method of supplying a plurality of eye floor plates 5 stacked one above the other in the stocker 40 one by one from the stocker 40 onto the upper surface 2 of the embankment 1.

[0039] Regarding the plurality of eye floor plates 5 stacked one above the other in the stocker 40, as shown by the white arrows in FIG. 5, first, by the operation of the discharge unit 50, they are discharged substantially horizontally from the stocker 40 toward the receiving portion 45a of the guide unit 45. After the discharged eye floor plate 5 hits the front wall 46 of the receiving portion 45a of the guide unit 45, it falls (free fall) onto the upper surface 2 of the embankment 1 through the cylindrical portion 45b. Here, the supply unit 70 realizes the function of supplying the plurality of eye floor plates 5 stacked one above the other in the stocker 40 one by one onto the upper surface 2 of the embankment 1. Further, the guide unit 45 realizes the function of guiding the eye floor plates 5 discharged from the stocker 40 by the discharge unit 50 toward the upper surface 2 of the embankment 1. Further, the guide unit 45 may also realize the function of correcting the orientation and posture of the eye floor plates 5 discharged from the stocker 40 by the discharge unit 50.

[0040] Next, the joint cutting operation using the joint board inserting device 10 will be described with reference to FIGS. 6 to 8. FIGS. 6 to 8 show a method of inserting the joint board 5 into the embankment 1. In the following description, regarding the plurality of joint boards 5 sequentially placed on the upper surface 2 of the embankment 1, the symbol of the n-th placed joint board 5 is set as "5-n" (n is a natural number).

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

[0042] Thereafter, as shown in FIGS. 6(B) and (C), the backward movement of the base machine 20 and the placement of the joint board 5 on the upper surface 2 of the embankment 1 using the supply unit 70 are repeated, and as shown in FIG. 6(C), the insertion unit 60 is positioned directly above the joint board 5-1. The step of moving the base machine 20 backward corresponds to the "movement step" of the present invention. That is, in this step, the base machine 20 is moved so that the insertion unit 60 is positioned directly above the joint board 5-1. In the present embodiment, the interval between adjacent joint boards 5 is, for example, about 10 cm.

[0043] Next, as shown in FIG. 7(E), the joint board 5-1 is inserted into the embankment 1 to a predetermined depth while being bent by the insertion unit 60 (insertion step). At the time of this insertion, while the blade 67 is vibrated by the vibration device 66, the telescopic cylinder 62 is extended downward to lower the blade 67, and the joint board 5-1 is inserted into the embankment 1 while being bent by the blade 67. The bent joint board 5-1 is in a so-called double-folded state, but it does not have to be evenly folded in half.

[0044] Next, as shown in FIG. 7(O), the telescopic cylinder 62 is contracted to raise the blade 67 (lifting step).

[0045] Next, as shown in Fig. 7(C), the base machine 20 is retracted (moving step) so that the insertion portion 60 is positioned directly above the eye floor 5-2.

[0046] Next, as shown in Fig. 8(F), the eye floor 5-4 is placed on the upper surface 2 of the dike body 1 using the supply unit 70 (placing step).

[0047] Next, as shown in Fig. 8(G), the eye floor 5-2 is inserted to a predetermined depth within the dike body 1 while being bent by the insertion portion 60. At the time of this insertion, while vibrating the blade 67 by the vibration device 66, the telescopic cylinder 62 is extended downward to lower the blade 67, and the eye floor 5-2 is inserted into the dike body 1 while being bent by the blade 67. Regarding the bent eye floor 5-2 as well, similar to the aforementioned eye floor 5-1, it is in a so-called double-folded state, but it does not necessarily have to be evenly folded in half.

[0048] Hereinafter, by sequentially repeating the aforementioned pulling-up step, moving step, placing step, and insertion step, a plurality of eye floors 5 are inserted into the dike body 1 (see Fig. 8(H)). Here, Fig. 8(H) shows a state where 10 eye floors 5 (5-1 to 5-10) are inserted into the dike body 1, but it goes without saying that the number of eye floors 5 inserted into the dike body 1 is not limited to this. For example, at a joint cutting location with a construction extension of 100 m, approximately 100 eye floors 5 can be inserted into the dike body 1.

[0049] In addition, in this embodiment, the insertion step is performed after the placing step, but alternatively, the insertion step may be performed prior to the placing step. Or, at least a part of the placing step and at least a part of the insertion step may be performed simultaneously.

[0050] By the way, in the conventional joint cutting work, for example, when inserting one eye floor into the dike body using the joint cutting machine disclosed in Patent Document 1, it is necessary to attach an eye floor having a J-shaped cross section to the joint cutting plate constituting the joint cutting machine, and this attachment work was carried out manually by an operator.

[0051] In this regard, according to the present embodiment, this mounting operation can be omitted, so that the manual work by the operator can be reduced.

[0052] According to the present embodiment, the blind floor inserting device 10 includes a base machine 20 having a vehicle body 21 capable of traveling on the upper surface 2 of a construction object (for example, a dike body 1), and a swivel body 22 rotatably provided on the vehicle body 21, an arm portion 30 having a base end portion pivotally supported by the swivel body 22 and capable of swinging, a stocker 40 provided on the swivel body 22 and capable of loading a plurality of blind floors 5, a supply portion 70 provided on the swivel body 22 and / or the stocker 40 and capable of supplying the plurality of blind floors 5 loaded on the stocker 40 one by one onto the upper surface 2 of the construction object (for example, the dike body 1), and an insertion portion 60 provided at the tip end portion 33 of the arm portion 30 and capable of inserting the blind floor 5 supplied onto the upper surface 2 of the construction object (for example, the dike body 1) into the construction object (for example, the dike body 1). Therefore, the mounting operation of the blind floor 5 on the blade 67 can be omitted, so that the efficiency of the joint cutting operation for the construction object (for example, the dike body 1) can be improved.

[0053] Also according to the present embodiment, the supply portion 70 includes a discharge portion 50 that discharges the plurality of blind floors 5 loaded on the stocker 40 one by one outside the stocker 40, and a guide portion 45 that guides the blind floor 5 discharged by the discharge portion 50 toward the upper surface 2 of the construction object (for example, the dike body 1). Thereby, the blind floor 5 can be easily and accurately supplied to a predetermined position on the upper surface 2 of the construction object (for example, the dike body 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 located 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, so that 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, so that 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, but 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.
