Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an adhering soil removing jig which is attached to the tip of an excavating bucket of a shovel type excavator such as a backhoe and used for removing the level of a temporary material for earth retaining such as steel sheet pile or H-shaped steel.

[0002]

[Prior art]

 For temporary materials such as steel sheet piles for retaining soil used in underground foundation works and various civil engineering works and H-shaped steel for intermediate piles, primary excavation, secondary excavation, tertiary excavation ... In the process of advancing, especially when the stratum is a highly viscous soil, a large amount of soil (soil pavement) is attached, so it is necessary to remove this soil pavement. Currently, the work of dropping the horizon attached to the inside is performed manually by workers using a scoop or the like.

[0003]

[Problems to be solved by the device]

 However, it takes a lot of labor and time to manually remove the horizon with a scoop, and if the adhering force to the temporary material is lost due to the drying of the adhering soil, etc. However, since a large lump of soil that has peeled off may fall above the temporary material, it was extremely dangerous to work manually.

The present invention has been made under the circumstances as described above, and the purpose thereof is to perform a leveling work of a temporary material for earth retention by using an excavating bucket of an excavator. And it is to be able to do it easily and quickly.

[0005]

[Means for Solving the Problems]

 The above technical problems can be effectively solved by the present invention. That is, the attached soil removing jig for temporary material for soil retention according to the present invention is a plate-shaped jig main body that is detachably attached to the tip of the excavation bucket of an excavator, and the inside of the jig main body from both side edges. Toward the plate surface, and the container is slidably supported in the container and one end of each is pivotally attached near both end portions of the cutting edge of the jig body to project from the both side edges. A pair of movable plates, and a restricting means for restricting the retreat of the movable plate into the accommodation portion.

[0006]

[Action]

 The jig having the above-mentioned configuration is formed such that the cutting edge of the jig body can penetrate into the recess of the temporary material for earth retaining such as steel sheet pile or H-shaped steel. For example, the excavation bucket of a hydraulic shovel such as a mini backhoe. It is attached to the tip of and the adhered soil in the recess is peeled off by the operation of this excavation bucket. At this time, the cutting edge of the jig body scrapes off the adhering soil in front of the concave portion, and the pair of movable plates supported by the accommodating portion in the jig main body is moved from both side edges of the jig main body to the inner surface of the concave portion. Scratch off the adhered soil on both sides of the jig body by protruding so as to correspond to.

【Example】

 1A and 1B show a typical embodiment of the attached soil removing jig 1 of the present invention. FIG. 1A is a plan view thereof, and FIG. 1B is a side view thereof. The jig 1 includes a plate-shaped jig body 10, a pair of movable plates 20 and 20 protruding and retracted from both side edges 11 and 11, and a spring 30 as a restricting means for restricting the backward movement of the movable plates 20 and 20. Have and.

The jig body 10 has a substantially rectangular plan shape, and as shown in FIG. 4, is formed to have a width that allows it to enter the recesses of the steel sheet pile 4 and the H-shaped steel 5. A cutting edge 12 is formed at the tip of the jig body 10, and a required number of fitting portions 13 are formed at the rear end of the jig body 10. The housing portions 14 extend inward in the plate surface direction from the both side edges 11, 11. Has been formed. Each of the fitting portions 13 is fitted into an excavating claw 3a provided at the tip of an excavating bucket 3 of a mini backhoe 2 which is, for example, a shovel excavator shown in FIGS. 2 and 3, and is set from the outside in this fitted state. The jig body 10 can be firmly fixed to the excavation claw 3a by screwing the bolt 15.

The movable plates 20, 20 have a plan view of a substantially triangular shape or a fan shape, and both front and back surfaces thereof are slidably supported in the accommodating portion 14, and one end of the movable plates 20 and 20 are connected via a pivot 21. It is pivotally attached near both ends of the cutting edge 12 of the main body 10, swings in the surface direction around this pivot 21, and projects in and out from both side edges 11, 11 of the jig main body 10 in an appropriate angle range.

The spring 30 is interposed between the movable plates 20 and 20 in a compressed state to constantly urge the movable plates 20 and 20 in the protruding direction. Although the spring 30 is conceptually shown in FIG. 1, a leaf spring or the like can be selectively used when the spring 30 is housed in the narrow space of the housing portion 14. Reference numeral 22 is a locking portion that limits the amount of protrusion of the movable plate 20 by contact with a protrusion (not shown) formed on the inner surface of the accommodating portion 14.

As described above, the jig 1 of the present embodiment is attached to the excavation claw 3a at the tip of the excavation bucket 3, and by operating the excavation bucket 3 from the cockpit of the mini backhoe 2. As shown in FIG. 4, the soil deposited inside the recess 4a of the steel sheet pile 4 for retaining soil and the inside of the flanges 5a, 5a of the H-shaped steel 5 is scraped off.

That is, the excavation bucket 3 to which the jig 1 is attached is made to face the plate surface of the steel sheet pile 4 or the web 5c of the H-shaped steel 5 and is operated from the top to the bottom in the manner of excavation. The cutting edge 12 peels and removes the adhered soil on the front surface of the recess 4a or the front surface of the web 5c. At this time, the movable plates 20 and 20 are oriented at appropriate angles from both side edges 11 and 11 of the jig body 10 toward the inner surface 4b of the recess 4a of the steel sheet pile 4 or the inner surface of the flanges 5a and 5a of the H-shaped steel 5. And stick off the soil on both sides.

In the above-described embodiment, the movable plates 20, 20 appearing and retracting from both sides of the jig body 10 are elastically pressed against the other side surface by the urging force of the spring 30. The projecting angles of 20 and 20 may be adjusted in advance to the inner surface of the steel sheet pile 4 or the like, and may be fixed by an adjusting screw screwed into the jig body 10. Also, the shape and number of the fitting portions 13 and other detailed shapes may be used. Is also optional.

[0014]

[Effect of device]

 As described above, the attached soil removing jig of the present invention can be attached to the tip of the excavation bucket of a hydraulic excavator such as a mini backhoe, and the excavation bucket can be operated to remove the level of the concave portion of the temporary earth retaining material. Therefore, the risk of dropping a large lump of soil, such as when a worker manually drops the soil flat with a scoop, etc., is avoided, and the soil adhering to the front surface and both inner surfaces of the recess of the mating temporary material is removed at the same time. Therefore, the work can be performed easily and quickly.
