[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION This invention relates to a mountain consisting of a cutting beam jack installed between ridge panels installed on both sides of an excavation groove and an operation jig for operating the cutting beam jack. It relates to a stop device.

[0002]

2. Description of the Related Art There are cases where buried pipes such as drainage pipes and gas pipes are buried under the ground surface of roads and the like. After digging the excavation trench, protecting the left and right side walls with a retaining panel to prevent collapse, and installing a buried pipe in the excavation trench,
The retaining panel has been removed and backfilled.

In this case, a girder jack is installed between the left and right girder panels to support the girder panel, but it is necessary to temporarily remove the girder jack to fill the buried pipe. .

Conventionally, in order to temporarily remove the cut beam jack, the jack has to be removed by loosening the jack into the excavation groove. For this reason, the temporary removal of the girder jack was not only troublesome but also extremely dangerous.

The present invention has been made in order to solve the above-mentioned problems, and is a landscaping device which enables buried pipes such as drain pipes and gas pipes to be buried very safely under the ground surface such as a road. The purpose is to provide.

12a and a hook 12b rotatably provided at the tip of the arm portion 11.

Then, the hook 12a and the hook 12b are engaged with the engaging portions 8a, 8a of the rotating portion 8 to grip the rotating portion 8, and the arm 11 is rotated in the circumferential direction of the rotating portion 8 to jack the jack. The outer cylinder 6 can be easily turned from the ground.

FIG. 4 shows another operation jig, in which a tip end portion of an arm portion 11 is bent so that a grip portion 12 is eccentrically protruded from a material axis of the arm portion 11.

If this operating jig is used, even if the cutting beam 13 installed above the cutting beam jack 5 is in the way, the jack outer cylinder 6 can be easily turned avoiding the cutting beam 13. Can be.

In such a configuration, the left and right flaps 4, 4
In order to install the buried pipe 1 below the cutting beam jack 5 already installed in between, the tip of the left and right rods 7 and
One of the left and right connecting pins 9 connecting the two is pulled out from the connecting pin insertion hole 7b, and one of the rods 7 is separated from the flap 4. Next, the beam jack 5 is cut around the other connecting pin 9 as an axis.
Is rotated horizontally and attached to one of the retaining panels 3.

Next, the buried pipe 1 is suspended from the bottom of the excavation groove 2 by a crane or the like. Next, the cut beam jack 5 is bridged again between the flaps 4, 4, and one of the rods 7 temporarily separated from the flap 4 is connected again by the connecting pins 9.

Embodiment 2 FIG. FIG. 8 shows another embodiment of the landscaping device according to the present invention.

Reference numeral 14 denotes a rotating portion attached to the outer peripheral portion of the jack outer tube 6 for turning the jack outer tube 6, and FIG.
In the figure, reference numeral 15 denotes an operation jig for turning the jack outer cylinder 6. The rotating part 14 is configured to be able to rotate the jack outer cylinder 6 by a ratchet type rotating mechanism. Further, an engaging hole 14a for inserting the hooks 15a, 15a of the operation jig 15 protrudes from the outer peripheral surface of the rotating portion 14. Then, the hooks 15a, 15a of the operating jig 15 are inserted into the engaging holes 14a of the rotating section 14, and the rotating section 14 can be turned by the operating jig 15.
