Disclosed are a foundation having a chain cutter at the base during construction and a construction method of the same. A rock and soil conveying apparatus is provided inside or beside a foundation (1) having a chain cutter (3) at the base during construction, the base of the foundation (1) has a track (1-1), the chain cutter (3) is mounted on the track (1-1) during construction, and the chain cutter (3) is composed of a chain (3-1) and a rock and soil excavating cutter (3-2) fixed on the chain (3-1). A chain excavating apparatus mainly consists of the chain cutter (3) and a transmission apparatus, the transmission apparatus mainly being composed of a driving apparatus (4) and a sprocket (6). During construction, the driving apparatus (4) drives the chain cutter (3), the chain cutter (3) runs along the track (1-1), the cutter (3-2) at the base of the foundation (1) excavates rock and soil, which are removed by the rock and soil conveying apparatus, and the chain cutter (3) at the base of the foundation (1) and the foundation (1) descend together. The defects of the prior art are overcome, and since the foundation (1) itself has an excavating apparatus, the foundation (1) can be pre-formed in blocks at the factory, or can be constructed by pouring while descending in on-site fixed formwork, construction is simple, in particular waterproofing is especially good as descending is done as a whole, the construction period is short, and costs are low.

The invention relates to a drilling machine (10) for making an excavation in ground in a drilling direction, said drilling machine comprising: an anchor module (12) having an anchor device for preventing the anchor module from moving in the drilling direction relative to the ground by bearing against one of the walls of the excavation; a drilling module (20) provided with cutter members connected to the anchor module while being movable in translation relative to the anchor module; and movement means (35) for moving the cutter members in translation relative to the anchor module. The drilling module is also hinged relative to the anchor module, and the drilling machine comprises first path correction means (40) for causing the drilling module to pivot relative to the anchor module about a pivot axis (X) perpendicular to the drilling direction.

The invention relates to a trench cutter for producing a cut trench in the soil with a cutter frame, at least one pair of cutting wheels which are supported and driven in a rotatable manner on a lower end of the cutter frame, wherein each cutting wheel has a plurality of cutting teeth along its external circumference, and a discharge means with at least one discharge pump for discharging a cutting fluid from the cut trench in the region of the cutting wheels. According to the invention a switchover means is provided which is designed for switching the discharge means over to a flushing operation, in which a fluid flow generated by at least one discharge pump of the discharge means is generated onto at least one cutting wheel for flushing out the cutting wheel.

A counterweight assembly for a working machine comprising a counterweight having a mass for counterbalancing a working arm of the working machine, the counterweight comprising a mounting arrangement for the mounting of a heat exchanger thereon and defining an air flow path having an inlet and an outlet to permit air to flow through the heat exchanger when mounted thereon.

A wheel loader comprises a console box and a support component. The console box is disposed on the side of an operator's seat and is able to rotate in the forward and backward direction. The support component has a rotary shaft disposed in the left and right direction under the console box, and rotatably supports the console box around the rotary shaft between an operation position in which the console box is disposed horizontally and a retracted position in which the console box is rotated rearward from the operation position and is disposed at an angle. The location of the center of gravity of the console box is disposed more to the front than the rotary shaft at the operation position, and more to the rear than the rotary shaft at the retracted position.
