Description

[Detailed Description of the Invention] The invention of the present application is characterized in that it can be used in a detachable manner on an excavation plate for an excavation packet, particularly a packet that is an accessory of a power shovel-type excavator.

If there is a risk of landslides or runoff during root cutting work, hold down the mountain.

Although pile stops are more powerful than sheet piles and their shoring, the vertical sheet pile method or horizontal sheet pile method is generally used as the construction method for pile stops.

By the way, the use of iron sheet piles for piles for piles has become widespread, but when using Larsen type, Terrouge type or Ransom type iron sheet piles in the vertical sheet pile method, grooves are formed on the excavation side. Therefore, it becomes necessary to remove the soil stuck in the grooves of the sheet piles.

In the past, earth and sand were removed manually using buckets, shovels, etc., but given the current situation where the total length of driven sheet piles often extends over long distances, manual removal work is quite time-consuming. Not only does this require labor and difficulty, but it also impedes the speedy progress of construction.

In addition, the excavator cannot be used during manual removal work and must be on standby, which not only prevents efficient use of the machine but also forces unnecessary rent payments if the machine is rented. .

Therefore, the present invention makes it possible to remove earth and sand adhering to the groove of the sheet pile by mechanical operation using the side blade of the excavation plate that is detachably attached to the tip of the bucket, making the removal work easier. The purpose of this project is to ensure the speedy progress of civil engineering works.

To explain the structure of the present invention with reference to the illustrated embodiment, an elongated excavation plate 2 that is detachably attached to the tip of a packet 1 has a front blade 3 shaped over the entire length of the tip, and a rear blade 3 at the rear end. An arbitrary number of comb teeth 4 are provided along the longitudinal direction.

Further, the excavating plate is integrally provided with an arbitrary number of pockets 5 between each comb tooth, and by fitting the claws 6 of the packet into the pockets and fixing the shaft, the excavating plate is properly fixed to the packet.

At this time, each comb tooth is engaged with the tip of the packet in the gap between the claws of the packet.

Further, the excavation plate is provided with removable side blades 7, 7 on both side edges, and these side blades are formed between the bottom wall and a horizontal plate 7b protruding from the vertical wall of the base 7a having an L-shaped cross section. The excavation plate is fixed to the excavation plate by inserting both side edges of the excavation plate into the grooves and tightening them with connectors such as bolts and nuts.

The reason why the upper edge of the vertical wall of the base 7a is inwardly reduced and sharpened is to allow the side blades to cut sharply into the earth and sand when removing earth and sand attached to the sheet pile.

The side blade 7
can be moved and adjusted in the lateral direction relative to the excavation plate 2 as necessary.

In the above structure, if the excavation plate is attached to the tip of the packet and the packet is moved in the vertical direction,
A practical effect is achieved in that earth and sand adhering to the grooves of the sheet pile can be easily scraped off by the side blades of the excavation plate.

Therefore, it is possible to remove earth and sand without requiring a considerable number of workers as in the past, which makes it possible to allocate the removal workers to other works, which speeds up the overall progress of civil engineering work. can contribute to

Furthermore, not only can the excavator itself be used more efficiently, but also unnecessary rent payments can be avoided.

Next, by removing the side blade from the excavation plate or removing the excavation plate from the packet, it can be immediately used for other purposes such as root cutting work and leveling work, making it a practical tool that allows you to quickly perform various types of work with one machine. It's also effective.
