Description

[Detailed description of the device]

[0001]

[Industrial application]

 This plan intends to provide a removing device for removing mud adhered to the steel sheet pile while pulling out the steel sheet pile in the temporary construction work of civil engineering and building foundation work.

[0002]

[Prior Art]

 Conventionally, this kind of thing is as follows. 1. Four workers are placed while pulling out the steel sheet pile with a vibro hammer and holding a scoop to remove the mud. 2. After pulling out the steel sheet pile, remove the mud with a small backhoe bucket. 3. After pulling out the steel sheet pile, a worker holds a scoop to remove the mud.

[0003]

[Problems to be solved by the device]

 The conventional techniques described above have the following problems. 1. After pulling out the steel sheet pile, it takes time for the worker to remove the mud with a scoop. 2. After pulling out the steel sheet pile, it takes time to remove the mud with a small backhoe in order to clean it. 3. Four workers are assigned to remove the mud while pulling out the steel sheet pile, but the pulling speed of the vibro hammer is fast, so the pulling speed is slowed down, and the worker's fatigue level is high. I work a lot of times. In addition, it takes time to remove the steel sheet pile next time. 4. If the mud is not removed, it will fall from high places and pose a danger to workers.

The present application has been made in view of such problems of the conventional technology, and an object of the present application is to provide a device capable of solving the above problems.

[0005]

【Example】

 Examples will be described with reference to the drawings. 1 is a device for removing mud adhering to the steel sheet pile of the present invention. Reference numeral 2 is a well-known steel sheet pile, 2A is a center plate portion, and 2B is an inclined surface portion continuously provided at both ends of this center plate portion. Therefore, the mud removing device 1 is composed of a pair of front and rear device units 3 and 4 which are configured to be connectable and disassembleable.

The details will be described below in order. The front device unit 3 includes a vertical frame 3A formed by connecting the front wall 3A1 and the left and right walls 3A2 in a U-shape facing the rear of the plane, a top plate 3B stretched on the upper surface of the vertical frame, and a vertical frame 3A The bottom plate 3C stretched on the lower surface, the inner frame 3D stretched so as to abut the center plate portion 2A of the steel sheet pile 2 on the inner surfaces of the vertical frame, the top plate, and the bottom plate, and the upper surface of the top plate 3B. Left and right soil removal frames 3E fixed to contact the outer surface of the inclined surface portion 2B of the steel sheet pile 2, and left and right removal frames fixed to the lower surface of the bottom plate 3C so as to contact the outer surface of the inclined surface portion 2B of the steel sheet pile 2. It is composed of a soil frame 3F. In the figure, 3A11 is an opening formed in the front wall 3A1, 3A21 is an opening formed in the left and right walls 3A2, and 3D1 is an opening formed in the inner plate 3D.

The rear device unit 4 includes a vertical frame 4A formed by connecting a rear wall 4A1 and left and right walls 4A2 in a U-shape facing forward in a plane, and a U-shape extending forward on the upper surface of the vertical frame. A top plate 4B and a rear edge 4C, which is attached to the inner surface of the lower end of the vertical frame 4A in parallel with the top plate and has a U-shape facing forward. 4B of the steel sheet pile 2 arranged to act downward in the opening of 4B, the upper earth removing plate 4D that contacts the inner surfaces of the center plate portion 2A and the inclined surface portion 2B, and the horizontal direction in the opening of the rear projecting edge 4C. With a soil removal plate frame 4E arranged so as to abut the inner surfaces of the center plate portion 2A and the inclined surface portion 2B of the steel sheet pile 2, and the center plate portion 2A and the inclined surface portion of the steel sheet pile 2 on the lower surface of the rear projecting edge 4C. The lower part arranged so as to contact the inner surface of 2B It is composed of a soil removing plate 4F.

The lower soil removal plate 4F is connected to the rear projecting edge 4C by a pin 4F1 in the left-right direction, and a certain amount of movement in the front-rear direction is restricted by the front-rear stoppers 4F2, 4F3. Further, the upper earth removing plate 4D is connected to the top plate 4B by a pin 4D1 in the left-right direction, and a weight 4D2 is fixed to the upper surface of the upper earth removing plate. In the figure, 4A11 is an opening formed in the rear wall 4A1 and 4A21 is an opening formed in the left and right walls 4A2. T is a hanging metal fitting that is provided on the side surface of the front device unit 3 and the rear device unit 4 so as to be hung by the auxiliary winding wire. The right end of the device unit 3 and the right end of the device unit 4 are connected by a hinge portion 5, and the left end of the device unit 3 and the left end of the device unit 4 are projected from each other. A vertical pin 6A is inserted into the metal 6 to be detachable.

The present invention operates as follows. Step 1 After attaching the vibro hammer to the main winding wire of the crawler crane, pull out the steel sheet pile and place the chuck of the vibro hammer on the head of the sheet pile. Step 2 After pulling out the steel sheet pile slightly, lift the mud removing device with the auxiliary winding wire of the crawler crane and set it at the lowest position where it can be installed.

Third step When the vibro hammer is started, the mud adhered to the steel sheet pile is removed by the upper soil removing plate and the lower soil removing plate of the device due to the vibration force of the vibro hammer and the weight of the removing device. Fourth Step When the withdrawal of the steel sheet pile is completed, the removing device naturally separates from the steel sheet pile.

Fifth step: Stop the vibro hammer, and bite the chuck of the vibro hammer to the head of the next steel sheet pile. Step 6 After slightly pulling out the next steel sheet pile, lift the removal device with the auxiliary winding wire of the crawler crane and set it.

[0013]

[Effect of the device]

 Since the present invention is configured as described above, it has the following effects. 1. It is possible to remove the attached mud while pulling out the steel sheet pile. 2. After installing the mud removal device on the steel sheet pile by two workers, no worker is required. 3. No special power is required for the mud removal device because it uses the vibration force of the vibro hammer and the weight of the removal device. 4. Four workers were required, but the number of workers can be two by using the removal device of the present application. 5. The mud removal work speed while pulling out the steel sheet pile equipped with the mud removal device of the present application can be about three times faster than the conventional speed.
