[Technical field to which the device belongs]

 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a guide wall for constructing a continuous underground wall, and more particularly, to a structure of a wall that serves as a guide for constructing an underground wall when constructing a continuous underground wall.

[0002]

[Prior art]

 When excavating a trench for a continuous underground wall, a concrete protection wall is provided at a certain depth at the upper end of the trench to prevent collapse of the upper edge of the trench. This is called a guide wall. When constructing a continuous underground wall, the power cable of the equipment for construction and the drain pipe for the wastewater treatment generated during the construction are complicatedly arranged in the site, especially the continuous ground. In the vicinity of the guidewall for building the inner wall, when the construction equipment moves and travels, there is a danger that the power cables and the like will be squished by the caterpillar and the like, which will hinder the construction. For this reason, conventionally, steel pipes for inserting power cables and the like have been buried in a plurality of places in the ground in the direction perpendicular to the extension direction of the guide wall, and the above-mentioned power cables are inserted into the steel pipes for insertion. I was dealing with it by inserting. Specifically explaining the conventional technology,

FIG. 3

[Fig. 4] As shown in Fig. 4, at the time of concrete driving of the guide wall 1 for constructing a continuous underground wall, the steel pipe 2 for insertion is inserted in the underground portion of the guide wall 1 in a direction perpendicular to the extension direction thereof. It is buried in multiple places on the circumference. This steel pipe 2 for insertion is protected by a cable for electric power required when constructing a continuous underground wall and a drain pipe for treating wastewater generated by the construction, which hinders the construction. It is stored in the insertion rope 2 for the purpose of organizing. According to this method, the electric power cable and the drainage pipe do not hinder the construction, and the purpose of protection and organization can be achieved.

However, in this method, when the power cable or the like is inserted into the steel pipe 2 for insertion, or when the construction site moves to the next block, the power cable or the like is pulled out from the steel pipe 2 for insertion. In addition, the guide wall 1 of the next block must be re-inserted into the steel pipe 2 for insertion, which not only takes time and labor for setup change, but also interrupts the construction during this time. If this is repeated many times, it may cause a great delay in the construction period, and further, water may be accumulated in the steel pipe 2 for insertion, which may cause electric leakage in the cable.

[0004]

[Problems to be solved by the device]

 The present invention has been made in view of the above points, and the purpose thereof is to easily install and move an electric power cable, etc., without interruption of construction, to keep the site tidy and to perform construction safely. It is possible to provide a guide wall for constructing a continuous underground wall.

[0005]

[Means for Solving the Problems]

 The present invention relates to a guide wall for constructing a continuous underground wall, in which a plurality of upper surface open passages having a depth and a width capable of accommodating cables and the like are formed at the top of the guide wall and the ground is provided with a ground opening. A guide wall for constructing a continuous underground wall, which is characterized in that it is provided so as to penetrate from the groove side of the intermediate wall toward the natural ground direction.

[0006]

[Embodiment of device]

 An embodiment of the present invention will be described below with reference to the drawings. In the description of the present invention, the same parts described in the section of the prior art will be designated by the same reference numerals.

<a> Overall configuration of guide hole for constructing continuous underground wall FIG. 5 is a vertical sectional view showing a construction state when constructing a continuous underground wall by the guide wall 1 for constructing a continuous underground wall. 6 shows the whole top view. As shown in FIG. 6, the entire guide wall 1 is arranged in concentric circles on the inner and outer sides of the continuous underground wall 4 so as to face each other, and an open top passage 3 is provided at the top of the guide wall 1.

<B> Detailed Structure of Guide Wall FIG. 1 is a vertical cross-sectional view of the guide wall 1. An upper surface open path 3 is provided at the top of the guide wall 1. The upper surface of the upper surface open path 3 is opened to facilitate the storage and removal of cables and the like. The width and depth of the open top passage 3 should be such that the cable or drainage pipe is accommodated and the space has a space on which earth or sand or crushed stones as a protective material can be backfilled. Good. FIG. 2 is a partial perspective view showing only the outside of the guide wall 1, and an upper surface open passage 3 is provided across the guide wall 1 in a direction substantially orthogonal to the extending direction. The upper surface open path 3 is provided so as to oppose an arbitrary position on the circumference of the guide wall 1 on the outer side and the inner side of the continuous underground wall. In forming the cross-section of the upper surface open passage 3, any method may be used, such as partitioning with a form at the time of concrete driving of the guide wall 1 or providing a U-shaped groove.

[0009]

[Action]

 <A> Installation on open upper surface As shown in FIG. 6, the present invention is arranged so as to face any position on the circumference of the outer and inner guide walls 1 provided so as to sandwich the continuous underground wall 4. It is sufficient to simply drop the power cable 6 of the construction equipment 5 and the drain pipe (not shown) for the waste water treatment generated during the construction (not shown) into the groove of the upper open path 3 provided. .

<B> Backfilling of open top road After the electric power cable 6 and drainage pipe are dropped into the groove of the open top road 3, the construction equipment 5 is easy to run on the sand, crushed stone, etc. Backfill. As a result, the power cable 6 and the drain pipe are protected from damage when the construction equipment 5 is running.

<C> Pulling up from open upper surface When moving the construction site or removing it at the completion of construction, remove the backfilled earth and sand, crushed stones, etc., and then remove the power cable 6 and drain pipe etc. from above. Simply pull up from the groove of open path 3 and move to the next construction site, or just remove it.

[0012]

[Effect of device]

 Since the present invention is as described above, the following effects can be obtained. <B> To install the power cable and drainage pipe, simply drop it into the open road. <B> In order to make construction equipment easy to run and to prevent damage to power cables and drainage pipes, it is only necessary to backfill earth and sand, crushed stone, etc. into the open road. <C> When moving or removing electric power cables or drainage pipes, remove the soil and crushed stones from the open road, and lift and move the electric power cables and drainage pipes. <D> It is easy to move electricity cables and drain pipes, and it is possible to eliminate the waste of construction time such as interrupting construction work when moving.
