A diaphragm wall is an underground structure that replaces a caisson.
It is formed for uses such as rigid foundations for high-rise buildings, foundations for tower-shaped buildings, and underground tank walls. To create such an underground continuous wall, first, a wall-shaped trench is dug underground using a trench excavator. Next, reinforcing bars are placed in the excavated trench, concrete is poured from above ground to form a wall of one element, and these elements are connected to form a continuous wall as a whole underground. It is something.

に溝孔を掘削できない不具合がある。 Various trench drilling machines have been proposed in the past as trench drilling machines suitable for such underground continuous walls.
For example, an excavator has been proposed in which a plurality of vertical shafts are arranged in parallel and bits are arranged alternately and overlappingly at the lower ends of the vertical shafts, thereby excavating a trench hole. However, in such a trench drilling machine having a vertical rotation axis, there is a problem in that both ends of the trench are formed in an arcuate shape because the bit rotates in a horizontal plane. Furthermore, in the underground continuous wall construction method that does not use rocking pipes, after pouring concrete, the end face of the existing concrete foundation is excavated while an adjacent trench is excavated, but since the bit rotates in a horizontal plane, the excavator itself is There are problems such as vibration and not being able to drill a groove in a predetermined shape and position.

ようになる。 Since such a trench excavator having a vertical rotation shaft cannot produce a trench with a rectangular cross section, a trench excavation machine having cutters attached to both ends of the horizontal rotation shaft has been proposed. For example, Publication No. 50-2242, Special Publication No.
Excavators such as those disclosed in Publication No. 56-4692 fall under this category. However, in the trench hole excavators described in these publications, the gap between the drum cutters provided at both ends of the horizontal rotating shaft becomes an uncut part, creating an uncut part that creates resistance during excavation. Since the mouth is located at the top of the drum katsuta,
There is a problem with soil removal being poor and slime remaining at the bottom of the hole.
Since the drum cutters are placed on both sides of the support for the horizontal rotating shaft, in order to rotate the horizontal rotating shaft, a power transmission means must be placed in the center to rotate the horizontal rotating shaft. This is because in order to prevent interference between the drum cutter and the drum cutter, it is necessary to separate the drum cutters on both sides by at least the space of the support body. If an attempt is made to narrow the spacing between the cutters in order to reduce the uncut portion, the space for the power transmission means becomes narrower, sufficient power transmission is not achieved, and the strength of the support is reduced. On the other hand, if sufficient power transmission is to be achieved, a gap corresponding to the space must be provided between the cutters, which results in the problem of leaving a large portion uncut. This kind of unexcavated area makes it difficult to carry out the trench excavation work itself smoothly, and the reverse suction port is located at the top of the drum cutter, so the soil removal efficiency is poor, and the unexcavated part remains and creates slime on the bottom of the trench. remains, causing problems with the strength of the diaphragm wall itself.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to propose a trench hole excavator that can form an underground continuous wall with the necessary strength without leaving any unexcavated portions.
