DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates, on the earth retaining apparatus in civil engineering methods and instrumentation <br/> location list.

[0002]

2. Description of the Related Art In general, when a pipe such as an underground wire or an electric wire pipe is continuously buried in the ground such as a road surface, when asphalt or the like is laid on the ground, first, an asphalt cutter or the like is used. Construct two cuts on the asphalt surface to make the width of the groove, then cut the asphalt surface using a general excavator, etc., and excavate and discharge earth and sand to a depth that does not require earth retaining over a predetermined length A large number of sheet piles are erected along the side walls of the groove, and the sheet piles are supported by beams along the groove from the inside of the groove (called bellows). It is supported by a beam (cut beam), excavating a deeper groove while driving a sheet pile with a general-purpose device and retaining the soil, and after laying a pipe, backfilling the earth and sand, rolling the sheet pile while rolling Pull out one by one, the whole After backfilling, the surface is restored by the temporary pavement, are embedded continuously tube into the ground by repeating this.

[0003] However, conventionally, sheet piles, beams and excavators, that is, backhoes, which are general-purpose materials, have been used, despite the fact that the above-mentioned work continuously performs civil engineering work of a fixed shape.

[0004]

By the way, as described above, when a conventional sheet pile retainer is installed and a continuous pipe is buried by a general-purpose excavator, a general citizen can pass near the pipe, Regardless of where you live, it generates dust and noise, which is a problem. In addition, there is a need for a place for temporarily placing a sheet pile, a beam, and an excavator used for construction, and there is a problem that traffic is easily hindered on a road surface. Furthermore, conventionally, since the work is performed outdoors, there is a problem that work is difficult or impossible in rainy weather, and a decrease in work efficiency due to weather or climate is inevitable. In addition, the conventional method requires a great deal of labor to install and remove the earth retaining work manually by an operator, and the danger of the operation remains.

The container constructed as described above can be moved to a place where a pipe is to be laid while the excavating device and the retaining device are stored, so that the material necessary for retaining and a general-purpose excavator are temporarily stored. Is unnecessary, and if it is on the road, traffic prevention can be minimized. In addition, this container has a bottomless box shape, and the inside and outside are separated by a roof, side walls, windows and a lower enclosure, which reduces work efficiency even in rainy weather or in weather or weather that is not suitable for outdoor work Construction work can be performed without any trouble, and at the same time, noise and dust from the construction work are not emitted outside. In addition, since the outside light is taken in by the window 32, when the outside is bright, the inside illumination is unnecessary.

The excavator is suitable for excavating a ditch, and excavates earth and sand by extending the rail up and down from a height corresponding to the depth of the ditch being excavated by moving the rail up and down. It can move and discharge earth and sand. According to this device, a general-purpose excavator, that is, a space required for turning an arm such as a hydraulic shovel or a space required for an arm height at the time of unloading is unnecessary, and excavation inside a container becomes possible. As a result, the space required during construction for laying underground objects can be minimized.

Further, the retaining device is suitable for retaining the side wall of the groove and is detachable from the rail. Therefore, when the container is moved, it can be connected to the rail and pulled up and stored inside the container. Can be used separately from the rail by lowering the rail and installing it at the bottom of a shallow groove. When excavating a deep trench, excavate while extending the sheet pile into the ground with a cylinder from the retaining frame. As described above, the earth retaining device requires almost no manual operation by an operator, and can improve the operation efficiency and safety. The synchronizing device has an effect of keeping the two rails horizontal at the same height, and enables the above-mentioned excavator and earth retaining device to be smoothly operated.

At the same time, a shallow groove b having a groove depth of 1 m which does not require earth retaining is excavated while discarding it in the earth discharging bucket 36 outside the container 1. Fig. 11 (a), (b)
11 shows a second step, as shown in FIG. 11 (a), after the soil retaining device 3 stored in the container 1 is separated from the rail 6 at the bottom of the shallow groove b and installed, and the sheet pile 4 is moved to the cylinder. A deep groove c having a groove depth of 2 m as shown in FIG.

FIGS. 12 (a), 12 (b) and 12 (c) show a third step. After the sand d is laid at the bottom of the groove c as shown in FIG. 12 (a), FIG. A buried object (pipe) a is laid in the groove c like
After that, as shown in FIG.
Compact. FIGS. 13 (a), (b) and (c) show a fourth step,
After raising the sheet pile 4, lowering the saddle 9, and connecting the retaining frame as shown in FIG. 13 (a), as shown in FIG. 13 (b),
As shown in FIG. 13 (c), the cut beam is reduced, and the trench is backfilled with earth and sand while raising the retaining device 3. Then, as shown in FIG. 14, the arms 10 to 12 of the excavator 2 are bent in a dogleg shape and accommodated in the container 1.
