Description

[Detailed description of the invention] [Industrial application field] This invention is a method for removing soil from steel sheet piles when pulling out the steel sheet piles that have been driven into the ground by a steel sheet pile pulling device. Regarding the collecting device.

[Conventional technology]

Currently, with urban redevelopment, the construction of housing, elevated roads, subways, water and sewage systems, etc. in urban areas is rapidly increasing. To carry out these works, it will be necessary to excavate the ground vertically and deeply, but retaining walls will be installed to prevent the surrounding ground from collapsing. Steel sheet piles are driven into the ground as this earth retaining wall, and at that time, noiseless and vibrationless steel sheet pile press-in/extraction equipment is used to maintain the environment in residential areas and the like. Steel sheet pile press-in/extraction equipment is
It is equipped with a gripping part that grips the steel sheet pile from both sides, and a transfer part that moves the steel sheet pile up and down by moving the gripping part up and down at a certain interval, and the steel sheet pile gripped by the gripping part is transferred by the transfer part. It is something that is forced into the ground or pulled out of the ground.

Here, steel sheet piles are not disposable, but
Since it is used repeatedly, it is generally pulled out of the ground and stored after the work is completed.
Therefore, when pulling the steel sheet piles out of the ground, it is necessary to remove soil that has adhered to the steel sheet piles. Conventionally, in order to remove soil adhering to such steel sheet piles, a worker used a shovel to scrape the soil off the steel sheet piles.

[Problem that the invention attempts to solve]

However, in the above-mentioned conventional soil removal method, a worker to remove the soil must always be near the steel sheet pile, and a worker for this purpose is required. The disadvantage is that the work efficiency is not good because the workload of the steel sheet pile pulling operation has to be matched to the work pace of the earth removal workers.

This idea was made in view of the above circumstances, and is a soil removal device that eliminates the need for workers for soil removal from steel sheet piles, performs soil removal work at the work pace of steel sheet pile pulling equipment, and improves work efficiency. is intended to provide.

[Means for solving problems]

This idea involves gripping the steel sheet piles to be pulled out of steel sheet piles that are horizontally arranged in multiple rows and driven into the ground, and pulling the steel sheet piles out of the ground by raising the gripping part. In the soil removal device of the extraction device, a soil removal member having a fitting hole having approximately the same shape as the cross section of the steel sheet pile is installed in the fitting hole at a position below the gripping portion of the steel sheet pile held by the gripping portion. The steel sheet piles are fitted and slidably disposed, and the earthwork member and the steel sheet pile adjacent to the steel sheet pile to be pulled out are connected by a connecting member so that the rise of the earthwork member is restricted. It is characterized by being connected.

〔Example〕

Embodiments of this invention will be described below with reference to FIGS. 1 to 4.

Figure 1 is a front view showing a steel sheet pile pulling device and a borrowing device, Figures 2 and 3 are diagrams showing a borrowing member, and Figure 4 is a front view showing a steel sheet pile pulling device and a borrowing device. It is a figure showing a borrowing member. In the figure, numeral 1 is the ground. On the ground 1, steel sheet piles 2a, 2b, 2
c, ... are connected to each other and driven into the steel sheet piles 2a, 2b, 2c, ....
is installed. The steel sheet pile pulling device 3 includes a device main body 4, a holding section 5 that holds the device main body 4,
6, clamping parts 7, 7 for moving the device main body 4 along the horizontally arranged steel sheet piles 2a, 2b, 2c, . . ., and a gripping part 8 for gripping the steel sheet pile 2a to be pulled out.
and a transfer section 9 that moves the grip section 8 up and down at predetermined intervals. Further, below the grip part 8, a dori member 10 is fitted and installed on the steel sheet pile 2a. Next, the earthwork member 10 will be explained using FIGS. 2 and 3. The earthwork member 10 includes a base 12 in which a fitting hole 11 that fits with the shape of the cross section of the steel sheet piles 2a, 2b, 2c, ..., and a base 1 are formed.
A reinforcing plate welded between the main wall 13, side walls 14, 15, and sub wall 16 vertically welded to the base 12 along the circumference of the fitting hole 11 of No. 2, and the side walls 14, 15. 17, the main wall part 13 and the sub-wall part 16 are installed parallel to each other with the fitting hole 11 in between, and the side walls 14 and 15 are welded to both ends of the main wall part 13. It is said that the structure is as follows. and,
As shown in FIG. 4, chain parts 1
One end of the chain part 18 is attached, and the other end of the chain part 18 is connected to a fixing part 19 fixed to the upper end of the steel sheet pile 2b adjacent to the steel sheet pile 2a to be pulled out.

In order to remove the soil attached to the steel sheet piles 2a by the soil removal member 10 of the steel sheet piles 2a of the steel sheet pile pulling device 3 configured in this way, first, the steel sheet piles 2a, 2b, 2c, which are arranged in a row, are removed. The steel sheet pile 2a driven into the ground is gripped from both sides by the gripping part 8 of the steel sheet pile pulling device 3 installed on... Next, steel sheet pile 2
The grip part 8 holding the object a is lifted up to a predetermined height by the transfer part 9. At that time, even if the steel sheet pile 2a is pulled upward, the dori member 10 is connected to the steel sheet pile 2b that is driven into the ground via the chain part 18, so It will slide. By repeating such a pulling operation of the steel sheet pile 2a, the earth removal member 10, which slides relatively, can scrape off and remove the soil adhering to the steel sheet pile 2a. In addition, the earthwork member 10 includes
Since the main wall portion 13, side walls 14, 15, and sub-wall portions 16 are provided as guide plates for the dori member 10 to move smoothly relative to the steel sheet pile 2a, the dori member 10 can move smoothly relative to the steel sheet pile 2a. , and the steel sheet pile 2a.

[Effect of idea]

As described above, the steel sheet pile borrowing device according to this invention has a borrowing member slidably disposed below the gripping part of the steel sheet pile held by the gripping part, and a part adjacent to the borrowing member. Since the structure is simple, simply connecting the steel sheet piles with the steel sheet piles using a connecting member, the installation work to the steel sheet piles can be carried out in a short time.

In addition, there are no special operating procedures for this device alone, and when the steel sheet pile is pulled out by the gripping section, the earth removal members slide relative to each other and the soil on the surface of the steel sheet pile is scraped off. There is no need for the steel sheet pile to be attached to the steel sheet pile at all times, and there is no need for workers to remove the earth, improving work efficiency.

Furthermore, it is possible to perform the work of pulling out steel sheet piles in the work space of the steel sheet pile pulling device.
