(Prior Art) When constructing the above-mentioned buried object in the lower part of the U-shaped groove so as to traverse it, conventionally, as shown in FIG. 9, an operator gradually excavates under the U-shaped groove 1 with a scoop or the like. In order to prevent the U-shaped groove 1 from collapsing, the support material 2
Was inserted to support the U-shaped groove 1 and the buried object was inserted into the opening 3 formed by excavation, and then the opening 3 was backfilled with earth and sand.

However, according to this conventional method, the operator must carefully excavate under the U-shaped groove 1 and insert the support material 2, and after burying, must refill under the U-shaped groove 1,
In this case, it is difficult and time-consuming to put the earth and sand in the lower part of the U-shaped groove 1. Therefore, firstly, the construction efficiency is poor, and secondly, the U-shaped groove 1 may be collapsed if the support member 2 is attached improperly. Thirdly, there is a problem that the U-shaped groove 1 may collapse at a later date because it is difficult for soil to enter the opening 3 below the U-shaped groove 1 in the backfill character.

Japanese Laid-Open Patent Publication No. 57-44093 discloses a method of burying a water supply pipe under a structure such as a fence or U-shaped groove. First, the vertical holes on both sides of the structure are excavated, and an operator drills one vertical hole. Inside, the operator holds the cutting tool with screw blades in which the rotational force from the power plant on the ground is transmitted through the flexible shaft, and the horizontal hole is provided between the vertical holes, and the water supply pipe is provided in the horizontal hole. A method of inserting and burying is disclosed. However, according to this method, when performing the excavation work, the operator must enter the vertical hole and hold the screw blade-equipped cutting tool to perform the excavation, which is a problem in terms of work safety. Since it is necessary to excavate a heavy cutting tool by human power, it is necessary to perform work in a state covered with mud, for example, in a soil condition where water comes out. There was a problem with it. In addition, since a cutting tool is manually supported to excavate a lateral hole, a hole having a large diameter cannot be cut, and there is a problem that it is limited to a small-diameter household water supply pipe and the like and its application range is narrow.

(Means for Solving the Problems) In order to achieve this object, in the present invention, when a buried object is constructed so as to cross the surface of the ground or a lower part of the structure near the surface, at least one side of the structure. A groove or a hole-shaped recess is excavated deeper than the structure, and a rotary bucket with a drive unit attached to the tip of the articulated arm of the hydraulic excavator so that each of them can take a horizontal position in the front-rear direction A circular hole is formed below the wall in a direction transverse to the structure, a tube having an outer diameter matching the hole is inserted, and both ends of the tube are provided on both sides of the structure. The method is characterized in that, after being penetrated between the recesses, the embedded object is inserted into the tubular body.

(Operation) According to the present invention, a rotary bucket equipped with a driving device is attached to the tip of a multi-joint arm of a hydraulic excavator so that each of the articulated arms can assume a horizontal posture in the front-rear direction. It is a method used for burying pipes, with the hydraulic excavator positioned on the front side or the back side of the structure, and the operator of the hydraulic excavator operates the multi-joint arm to rotate the bucket horizontally and rotate it from the hydraulic excavator. It becomes possible to excavate a circular lateral hole from the front side or the back side when viewed. Therefore, an operator can perform excavation without entering a groove or hole to be excavated on both sides of the structure.

Also, since a hydraulic excavator having an articulated arm is used, after excavating half of the lateral holes by advancing the bottom of the rotary bucket forward from one side of the structure,
If you operate the articulated arm to straddle the structure, flip the rotary bucket on the opposite side across the structure, and excavate the other half in the opposite direction to the previous time, it will already be at the bottom of the structure. A side hole can be completed by abutting with a part of the side hole being drilled, and a side hole having a length twice that of the rotary bucket can be drilled.

Thus, by excavating a horizontal hole by using a rotary bucket such as an earth drill bucket 4 with a driving device, which is attached to the tip of the articulated arm of the hydraulic excavator so as to take a horizontal posture in the front-rear direction, , The U-shaped groove 1 and the like can be excavated on both sides of a structure such as grooves or holes to be excavated on the both sides of the structure, and the operator can enter the vertical hole to support the excavator. The safety is improved and the burden on the operator is significantly reduced as compared with the method of excavating the ground. Also, since it is a method of working by attaching a rotary bucket to the multi-joint arm of the hydraulic excavator, it is possible to attach a rotary bucket with a weight that cannot be supported by human power and perform lateral hole excavation. The diameter of the pipe that can be installed is not limited, and a pipe with a large diameter can be installed.

In the case of carrying out the present invention, the recesses 8a and 8b may be provided first, and the hole 15 may be opened at one time from one side so that the two communicate with the hole 15, but this is shown in the above embodiment. As described above, the hole 15 is provided as a blind hole so as to extend over the lower middle portion of the U-shaped groove 1, and the tube body 6 is inserted into the blind hole 15 to prevent the hole from collapsing, and the half hole is later opened. By excavating and penetrating the pipe body 6, the work can proceed without fear of collapsing the hole 15. Also, like this, half holes 15
By excavating, a small-sized rotary bucket or hydraulic excavator such as the earth drill bucket 4 can be used for the work.

(Effects of the Invention) As described above, the method of the present invention is a method of excavating a circular hole that is hard to collapse under a structure, and then inserting a tube into the hole to bury it. Therefore, excavation work and backfilling work of the lower part of the structure, which requires careful attention, are not necessary, and of course, improvement in efficiency can be achieved.
INDUSTRIAL APPLICABILITY The present invention is a method of excavating a lateral hole using a rotary bucket equipped with a driving device, which is attached to the tip of a multi-joint arm of a hydraulic excavator so as to be able to take a horizontal posture in the front-rear direction. The excavation can be done without entering the ditch or hole to be excavated, and the safety is improved and the burden on the operator is increased compared to the method in which the operator enters the vertical hole to support the excavator and excavates. Is significantly reduced.
