Abstract

PROBLEM TO BE SOLVED: To improve the workability by mounting a bucket on the arm of a hydraulic excavator through a second arm, and mounting an auger device on the arm. SOLUTION: A bucket is installed to the arm 1 of a hydraulic excavator through a second arm 2 to perform an excavation under a structure. The bucket is then removed, and an auger device 4 and a tip screw 5 are mounted on the second arm 2 by using the wide working space excavated by the bucket. As occasion demands, a joining intermediate screw is mounted on the screw 5 to perform the excavation to an arrival side, and each screw is then pulled out to form an excavated hole. A long pipe having a cap mounted on the top end and a pushing cap mounted on the rear end is inserted into the excavated hole, and pushed by the tip of the arm 2 so as to reach the arrival side. When the pipe length is insufficient, a pipe is joined by a socket, and the construction is performed in the same manner. Thus, a pipe can be laid under a structure without excavating the ground surface.

敷設した後埋め戻している。2. Description of the Related Art There are various types of pipes to be buried in the ground, such as sewer pipes, gas pipes, and water pipes, but most of them are excavated from the ground on public roads, laid down, and then backfilled.

ていた。[0003] However, if there is a large structure such as a concrete box or a common ditch for a waterway during excavation, it is impossible to excavate from below the ground. In addition, these pipes must be pulled out of each individual's house by pulling out branches. In this case, there are many places that cannot be cut because there are road gutters, house walls, and the like. Conventionally, such a place is often constructed manually, in which case a great deal of time and labor is required, and since the soil cannot be reliably secured, the construction has been performed with some awareness of danger.

法となっていた。[0004] In addition, various types of propulsion machines have been devised and put into practical use, not as human power but as a propulsion method. However, since all of them have a structure in which the starting shaft wall bears the reaction force during propulsion, the starting force is reduced. Excavation was very expensive and resulted in an expensive construction method even for short distances.

However, since there is no second arm as in the present invention, the underside of the structure is excavated in advance and the auger device is excavated. Since the space for installing the screw and the screw cannot be widened, the use site is limited, and it is rarely used.

By making the machine bear the reaction force without burdening it, the shaft construction cost is greatly reduced or reduced to zero, and the spacing between structures is narrow, so that the auger device, screw, etc., which is a propulsion work machine, can not be installed It was an object of the present invention to secure a work space in a place by excavating a lower side of the structure in advance.

出来る。In order to solve the above-mentioned problems, according to the present invention, an auger device is attached to an excavator that works by hydraulic pressure, and excavation is performed with a screw, so that manual work can be mechanized. Also, by making the excavator bear the reaction force for pushing the auger screw and the force for pushing the pipe, the construction cost of the shaft can be significantly reduced or reduced to zero.

スを確保することが出来る。Then, a second arm is attached to the tip of the conventional arm, and a bucket is attached to this tip. Thus, the work space can be secured even in a place where the propulsion work machine cannot be installed by excavating the structure lower side in advance and expanding the work space.

With such a structure, the lower side of the structure can be excavated by the arm and the bucket as shown in the figure.

を取外した先端で押し込む。When several screws are required to reach the position as shown in FIG. 3, the auger device is separated from the screws once, and an intermediate screw for a foot is attached. By repeating this, when the screw reaches the reaching side, if the screw is pulled out without rotating, a hole having a diameter substantially equal to the outer diameter of the screw remains (FIG. 4). As shown in FIG. 5, a cap is attached to the end of the pipe as long as space permits, a cap for pushing is attached to the rear end, and the hole is pushed with the auger device and the removed tip.

If the work space is not widened in FIG. 1, such installation cannot be performed.

離にならない限り障害は発生しない。FIG. 5 is a diagram in which a predetermined tube is pushed into the hole. When the screw outer diameter and the pipe inner diameter are almost the same, the screw slightly disturbs the surrounding soil. Therefore, a tip cap 7 is attached to the pipe tip to prevent soil from entering, a push cap 8 is attached to the rear end, and a screw is attached from the auger device 4. When the pipe is pushed in with the pushing pressure with the removed tip, the pipe enters the hole while consolidating excess soil around. If it does not reach the arrival side with one wire, it is joined with a socket joint and pushed in again. The socket joint is slightly larger than the outside diameter of the pipe, but no obstacle will occur in cohesive soil or sandy soil unless the distance is particularly long.
