摘要:
A system for uncovering and sealing a narrow trench. The system comprises several subsystems, including a work machine, a frame for providing a seal with the surface to be trenched, a saw blade, a vacuum system, a system for placing product, and a resealer. The blade includes rotatable tooth bits, which may be rotated and secured to create a blade for narrower or a wider trench. A removable cover and the blade are easily changeable. A ground engaging surface on the frame is manipulated to maintain a seal with changing ground surfaces. Additionally, the vertical location of the blade within the frame is adjustable to create a deeper or shallower trench.

The present invention relates to a ground sawing machine comprising a frame supported by rear wheels (34a, 34b) and front wheels (36a, 36b) arranged for moving the ground sawing machine over a surface (38). At least one motor (40, 6) and a saw blade (2) are mounted to the frame, at least one motor (40) being arranged to propel the saw blade (2) to cut against the surface (38). The pointing direction (80) relative the surface (38) of the rear wheels (34a, 34b) and/or the front wheels (36a, 36b) is adjustable by means of an electrically controlled actuator (56) which is controlled by means of control means (70, 71, 72) arranged to provide at least three different control signals, one for left turn, one for right turn and one for center. The control signal for left turn and right turn are arranged for adjusting the pointing direction (80) of the adjustable wheels (34a, 34b) correspondingly, and the control signal for center is arranged for adjusting the pointing direction (80) of the adjustable wheels (34a, 34b) to a predetermined value.

摘要:
Die vorliegende Erfindung betrifft eine Grabenfräse mit einem rotierenden Fräsrad 81) zur Herstellung von Gräben in der Breite des Fräsrades und mit einem Antriebsfahrzeug (30), wobei das Fräsrad (1) eine eine Rotationsachse (15) definierende, zentrale Nabe (2) und einen mit der Nabe (2) verbundenen Radkranz (3) aufweist, der über seine Breite hinweg und entlang seines Umfanges verteilt Fräselemente (4) aufweist, wobei die Nabe (4) innerhalb der Breite des Fräsrades liegt. Um eine konkrete Lösung anzugeben, wie eine Lagerung eines Fräsrades möglich ist, so dass das Fräsrad über die Nabe hinaus in den von dem Radkranz des Fräsrades gefrästen Graben eintauchen kann, wird erfindungsgemäß vorgeschlagen, dass die Nabe (4) durch mindestens einen Gabelschenkel (6) gehalten wird, welcher die Nabe (2) drehbar lagert und sich von der Nabe (2) ausgehend in radialer Richtung auf ein Niveau oberhalb der Nabe (2) und innerhalb des Fräsradprofiles (P) zum Radkranz (3) hin erstreckt und vor Erreichen des Radkranzes (3) in axialer Richtung nach außen über das Fräsradprofil (P) hinaus verschwenkt und radial an dem Radkranz (3) vorbeigeführt und mit der Halterung des Antriebsfahrzeuges verbindbar ist.

Eine Vorrichtung (4) zur Bearbeitung einer länglichen Vertiefung (1) im Erdreich (2) umfaßt mindestens einen Motor (7, 8) und von diesem angetriebene Fräswerkzeuge (9, 10), die um ihre Längsachse (RA) rotierend gelagert sind. Die Längsachse (RA) der Fräswerkzeuge (9, 10) verlaufen in einem Winkel (δ) zueinander, wobei die Mantelflächen (11, 12) der Fräswerkzeuge (9, 10) an einer Stelle ihres Umfangs unter Aufrechterhaltung eines Arbeitsspiels (15) derart beieinander liegen, daß eine durchgehende Arbeitsebene (AE) gebildet ist.
摘要:
The invention relates to a device for digging trenches and refilling them with earth, especially for laying pipes. Said device comprises a self-propelled travelling mechanism (2), said travelling mechanism supporting a machine frame (4) with an upper structure. The device also has a boom (6) which is mounted on said machine frame (4) in such a way that it can pivot, and a shovel bucket (16). Said boom has several boom arms (8, 10, 12) which are connected in such a way that they are articulated. The shovel bucket (16) is pivotably mounted at the free end of the boom (6). According to the invention, a milling/mixing rotor (22) is located on the shovel bucket (16).
摘要:
To construct an underground structure having smooth wall surfaces in a simple, safe and reliable way, plates (11,12) are buried in parallel, and soil and sand (G1) between the plates is removed. If the places where the plates are to be buried are loosened in advance, they can be buried more easily. A strut member (14) is interposed between the plates, which are used as both forms and sheathing. A hollow body, together with steel plates arranged on both sides of the hollow body, is buried into the ground, the bottom of the hollow body is closed with a shutter, the hollow body is drawn up together with soil in it, leaving the steel plates in the ground, and the remaining steel plates are used as both forms and sheathing. Reinforcement bars are disposed in the groove space thereby formed, and concrete is poured to build an underground structure.
