Description

The present invention relates to a panel erection machine for constructing a wall body whose construction period and construction cost are reduced by a minimum number of steps, and a wall body construction method using the same.

In the conventional wall construction method, a pile hole is excavated at a predetermined interval along a partition line of a place to be dug, and H steel is placed as a parent pile at a predetermined interval in this pile hole. After the soil cement was injected and solidified, the panel was inserted between the H steel grooves facing each other while digging inward from the row of H steel, and the earth was fixed to the outer site.
However, in this method, it is necessary to remove the solid soil cement in the installation portion for installing the panel, and the work is troublesome and the cost increases. Therefore, it is omitted to insert the soil cement to the upper end of the H steel. In many cases, the effect of retaining the earth could not be fully exhibited.

Therefore, the main pile panel construction method proposed in Japanese Patent Laid-Open No. 2000-17655 is a groove that can form a panel support groove after the cast H steel forms the main pile on the H steel before being inserted into the pile hole. A forming member is attached in advance, and placement is performed.
However, since this method requires a groove forming member to be attached to the H steel in advance, this groove forming member must be manufactured separately, and the lid portion and the reinforcing portion are broken off as the site is dug down. Therefore, there is a drawback that it takes time and work time.
Furthermore, the completed structure itself was not durable as a durable structure, and was not excellent in terms of aesthetics.

The panel laying machine is fixed to the upper end of the steel pipe pile, and the panel is placed by the pressing body, and then a new panel is placed adjacent to the placed panel. It is the wall body construction method which comprises the continuous wall body of a panel.

The gist of the present invention is a wall construction method characterized in that, in the wall construction method, a wall body is constructed by driving a panel having a scraper attached to a tip end thereof into the lowermost end.

In the present invention, since the parent pile that supports the panel is constructed with steel pipe piles, sufficient supporting force can be obtained without injecting the soil cement, so that the process of injecting the soil cement can be omitted and the hardening is awaited. Time is not needed. In addition, it does not require soil cement suspending work or guide forming members, and the construction period and cost can be reduced.
In addition, the panels can be produced in the factory in advance, saving labor and reducing the number of man-hours for on-site construction.

Since the panel is a durable member made of concrete or heavy anti-corrosion steel plate, it has excellent durability as a durable structure and can be used directly as a wall. In addition, when a surface with a design or the like is used, a beautiful wall can be obtained immediately after construction.
Moreover, since the guide part along the surface shape of the cast steel pipe pile was formed in the both-sides edge part of a panel, it can construct more reliably and rapidly.
Further, by attaching a scraper to the tip of the panel, it is only necessary to excavate the vicinity of the wall body without excavating the lower part, and there is an effect that it can be pressed with a small force.
Furthermore, at the time of border construction, it can be used as a fishing reef by forming a predetermined hole in the panel.

  In the best mode for carrying out the present invention, a steel pipe pile is placed on the ground at regular intervals, and a panel made of a durable member having a guide portion along the surface shape of the steel pipe pile is formed at the end. After placing the guide part at the end of the panel along the surface of the two steel pipe piles, and placing the panel by pressing it from its own weight or from above, a new one is installed adjacent to the placed panel. A wall construction method for constructing a continuous wall body of the panel and the whole is manufactured with a durable strength member, and a sealing material that conforms to the surface shape of the cast steel pipe pile is formed on both side ends. It is the panel formed in the contact part of a guide part and a panel.
