Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention particularly relates to a method of arranging a long pipe which is used when burying a long pipe in an excavated groove, and a method of burying a long pipe in a groove. The present invention relates to a soil retaining device for loading long pipes used in.

[0002]

2. Description of the Related Art Conventionally, the earth retaining device shown in FIG. 7 has been used for burial work for water and sewer pipes or gas pipes. This earth retaining device is used for earth retaining of the earth wall part excavated over a predetermined section (usually about 30 m),
It is mainly composed of a seating plate 2 and a retractable girder 4.

The seating plate 2 is usually 2-3
It has a horizontal length of about m and is composed of a plate 2a and vertical beams 1 provided at both left and right ends of the plate 2a. A mouth 7 is provided. A connection fitting 3 for mounting the seating plate 2 in the upward direction is attached to the upper portion of the vertical beam 1, and a cutting shoe 6 is attached to the lower end of the vertical beam 1 landing on the groove bottom.

At the time of assembly, the sheeting plates 2 which are arranged facing each other with a necessary space therebetween are connected by using the cross beams 4. Further, another seating plate 2 is overlaid on the upper side of these seating plates 2, these are connected by a connecting fitting 3 and fixed by wing bolts 8. In this way, the seating plates 2 are stacked in a plurality of stages to form a soil retaining device having a required height.

At the time of use, the assembled earth retaining device is carried into a previously excavated groove by using a crane or the like, and is installed at a predetermined position. Then, the box-shaped inside of the earth retaining device is excavated, the pressure hood 15 is fitted into the connecting fitting 3, and this portion is pressed to push the earth retaining device. Further, the seating plates 2 are stacked according to the depth of the groove, and this operation is repeated to sunk the soil retaining device to a predetermined depth. By the same operation, soil retaining devices are installed in series over a predetermined section in the groove. After arranging the soil retaining device and retaining the soil in this manner, the pipe body is thrown into the groove through the opening formed by the seating plate 2 and the both-sided beams 4 of the soil retaining device, and the soil is retained at a predetermined position. Perform burial work.

[0006]

The length of the seating plate 2 used in the soil retaining device is usually 2 to 3.
Since the distance between the beams 4 provided at both ends of the seating plate 2 is substantially the same, when the long pipe 10 longer than this distance is put into the groove, the long pipe 10 is inserted.
Cannot be placed in the groove in the horizontal direction.

For this reason, generally, as shown in FIG. 8, a method is used in which the long tube 10 is inserted in an inclined state in a tilted state. In this method, since the long pipe 10 is longer than the distance between the beams 4, it is necessary to remove some of the cut beams 4 at the portions through which the long pipe 10 passes in advance. Further, as shown in FIG. 9, when a long pipe 11 having a relatively large diameter is charged, the same method as described above is used, but in this case, a large number of the girders 4 are lengthened by the size of the diameter. Since it interferes with the input passage of the length measuring tube 11, it is necessary to remove as many cutting beams 4 as that.

As described above, conventionally, the long tubes 10 and 11 described above are used.
However, there is a problem in that the work is complicated because it takes time and effort to remove the cross beam 4 in the input path, and there is no choice but to insert the beam in an oblique direction.

On the other hand, in order to form an opening having a length twice that of the conventional one, a long beam having a length twice that of the seating plate 2 and extending between the seating plates 2 of adjacent soil retaining devices. A method is used in which a material (raising material) is used, and the material is bridged and supported inside the respective facing seating plates 2. In this case, if both ends of the uprising members that are provided facing each other are connected by the beams 4, the conventional
Since the distance between the double beams 4 is secured, the use of this as the opening facilitates the insertion of the long tube 11. However, in this configuration, in order to form the opening portion having the same width, it is necessary to excavate the groove width in consideration of the thickness of the wadding material, and the assembly becomes complicated. There is.
