Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a concrete dewatering device used for forcibly dewatering breathing water that remains on the surface of concrete after it is placed.

[Conventional technology]

The conventional method for dewatering the breathing water on the concrete surface is the so-called vacuum concrete method, in which a vacuum mat connected to a vacuum pump is placed on the concrete surface and the breathing water is forcibly sucked from the vacuum mat. something is known.

However, in the past, all the work of placing and moving the vacuum mat on the concrete surface was done manually by workers, which had the disadvantage of making the work itself inefficient and costly. . Furthermore, in places with large areas such as concrete floors, workers must enter the concrete floor to place and move the vacuum mats, which may damage the concrete surface or cause damage. Disadvantages such as suction by the vacuum mat not being performed as desired and, for example, only the area near the surface of the concrete is dehydrated, resulting in a difference in strength between the area near the surface and the center of the concrete, resulting in a decrease in overall strength. It was hot.

[Problem that the invention attempts to solve]

The present invention focuses on these conventional drawbacks, and its purpose is to automatically place and move the vacuum mat without damaging the concrete surface, and to implement the vacuum concrete method as desired. Providing concrete dewatering equipment.

[Means for solving problems]

The characteristic configuration of the concrete dewatering device according to the present invention is that the first ground support part that independently supports the fuselage frame and the second ground support part that independently supports the fuselage frame are relatively movable back and forth, and , a moving mechanism that is attached to the fuselage frame so as to be able to move up and down independently with respect to the fuselage frame, and that moves the first ground support part and the second ground support part back and forth relative to each other; and the first ground support part and the second ground support part. An elevating mechanism is provided for raising and lowering each support part relative to the body frame, and each of the ground surfaces of the first ground support part and the second ground support part is constructed of a vacuum mat for dehydration.

[Effect]

The second ground support part is lowered by the lifting mechanism to support the fuselage frame only by the second ground support part, and in this state, the first ground support part is moved forward or backward by the moving mechanism, and then the first ground support part is lowered. The aircraft frame is lowered to ground on the concrete surface by the lifting mechanism, and then, in that state, the first ground support part is lowered by the lift mechanism to support the fuselage frame only by the first ground support part,
In this state, by repeatedly moving the second grounding support part forward or backward by the moving mechanism and then lowering the second grounding support part to ground on the concrete surface by the lifting mechanism, the first grounding support part and the second grounding support part are moved. It is possible to walk on a concrete surface using the amount of movement forward or backward of the part as the stride length. Since the ground plane of each of the first ground support part and the second ground support part is composed of a vacuum mat, only the vacuum mat for sucking breathing water comes into contact with the concrete surface, and the other parts come into contact with the concrete surface. Since there is no contact with the running equipment, the roughness of the concrete surface due to running can be kept to a minimum. Furthermore, by appropriately driving the moving mechanism and the lifting mechanism as described above, the vacuum mats of the first and second grounding supports can be alternately lifted and placed on the concrete floor. Since the robot can automatically move forward or backward by walking rather than rolling, the vacuum mat, which is the only one in contact with the concrete surface, hardly damages the concrete surface.

[Effect of idea]

As described above, the dewatering work can be performed automatically and efficiently, and the surface of the concrete is hardly roughened during the dewatering work, and the suction and dewatering work using the vacuum mat can be carried out reliably.

A second ground support section is configured to independently support the fuselage frame by using the lower surface of the vacuum mat 30 as a contact surface to the surface of the concrete 37.

The vacuum mats 26, 28, 30 are connected to a vacuum pump 34 mounted on the machine frame 3 via pipes 31, 32, 33, respectively, and the breathing water sucked by the vacuum pump 34 is transferred to the machine frame 3. It is housed in a tank 35 placed on the top plate 15 of 3, and is configured to emit a signal based on detection by a level meter 36 when a desired amount is reached.
