Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a water absorber that absorbs shallowly spread water over a large area, for example, breathing water that oozes out after placing concrete.

[0002]

[Prior art]

 Water that was shallowly poured over a large area, especially when constructing a large-scale concrete structure, was included in the fresh concrete that was formed on the surface of the concrete after it was driven into the frame. If the breathing water that seeps out water is left to stand, it hinders the aging of the concrete in the part. In addition, when splicing the next fresh concrete onto the freezing water, a large amount of water may be mixed only in that portion, and the cement may be washed away from the fresh concrete by mixing it with water. For some reason, the concrete in that part will have low strength, and will eventually become a defective part of the constructed structure.

Therefore, the breathing water is removed after driving the fresh concrete, or before continuously driving the next fresh concrete.

[0004] In order to remove the breathing water and the like, conventionally, a worker often sucks the water with a rag or a sponge and squeezes it into a bucket or the like. This took a lot of manpower and was too time consuming to work. As a method of using a large-scale machine, a method of sucking water with a vacuum hose may be considered, but this also can only remove accumulated water within a small area near the tip of the vacuum hose at once, so a small area is required. Although effective against deeply-poured water, it was not very effective at eliminating shallow-poured water from large-area concrete pouring sites.

[0005]

[Problems to be solved by the device]

 The problems to be solved are (1) It is not possible to use a rag and a bucket as in the past as a device for removing water that has been shallowly collected over a large area, such as groundwater and breathing water. However, it is not efficient because it requires a lot of manpower, and even if a vacuum hose is used, water should only be absorbed near the suction port of the vacuum hose. (2) Even so, if the suction port of the vacuum hose is enlarged, the suction force will be weakened accordingly. (3) Therefore, none of the above is suitable as a device for absorbing and eliminating water that is shallowly accumulated in a wide area such as breathing water.

[0006]

[Means for Solving the Problems]

 The present invention was devised to eliminate water that was shallowly spread over a wide area such as the above-mentioned breathing water, and a water absorbing layer made of a water absorbing material such as sponge was attached to the surrounding area. A drum, a squeezing roller arranged on the outside of the squeezing roller to press the water absorbing layer, and a gutter disposed below the squeezing roller are provided, and the squeezing roller squeezes water such as breathing water absorbed in the water absorbing layer. It is a water absorption machine with a gutter configured to squeeze out and receive the water squeezed out by the gutter into a drain. In the above, it is also preferable that a water receiving bucket is provided first from the gutter, or that the gutter is further pressed against the water absorbing layer. It is also preferable that the squeezing roller is hollow and has a large number of small holes formed in the wall. As described above, it is possible to efficiently absorb and remove the water that is spread over a wide area such as breathing water.

【Example】

 Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the drawings. 1A and 1B are conceptual views of a water absorber with a gutter according to an embodiment of the present invention, wherein (1) is a plan view, (2) is a front view thereof, and (3) is a right side view of (2). However, as shown in each of the above figures, a water absorbing layer 2 made of a water absorbing material such as sponge or fiber is attached around the hollow drum 1.

In order to reduce the overall weight of the hollow drum, an aluminum alloy having a thickness of about 1 mm is used in the embodiment, and the rotary shaft 3 of the drum is attached to the center of the lids on both sides. Water receiving buckets 4, 4'and a handle 5 are attached to both ends of the drum 3 so that the drum can freely rotate.

Although the thickness of the water absorbing layer 2 is determined by the properties of the sponge or the like, in the embodiment, the thickness is 7 cm and is made of rubber that is compressed to about 0.8 cm when lightly pressed. It was effective with a sponge.

An arm 6 is further attached to the handle 5 attached to the rotary shaft 3 of the drum, and a rotary shaft 8 of a squeezing roller 7 is rotatably attached to the tip of the arm 6. The squeezing roller 7 is also hollow and is made of an aluminum alloy or the like. The surface of the squeezing roller 7 is provided with a number of small holes 9, 9 ... Was configured to be in pressure contact with the water absorption layer 2.

A gutter 10 is attached immediately below the squeezing roller 7, and the gutter 10 is configured so that the central portion is high and both end portions are low, as shown in FIG. 1 (2). It is configured so that the water flows to the water receiving buckets 4 and 4 ′ attached to both ends of the roller 1 by connecting the both ends.

The upper end of the gutter 10 on the drum side is attached in pressure contact with the water absorbing layer 2 as shown in the enlarged sectional view of FIG.

The above is the configuration of the water absorber of the embodiment of the present invention. The usage method and operation will be described below, taking the removal of breathing water as an example.

When the water absorber with the gutter of the present invention is placed on a fresh concrete placing surface that is shallow and widely covered with breathing water, and the handle 5 is manually operated and pushed horizontally, the drum 1 Moves while rotating.

At this time, the breathing water is sucked into the lower surface of the water absorbing layer 2 attached around the drum 1.

When this process is examined in detail, first, in the lower part of the water absorbing layer 2, the water absorbing material such as sponge is compressed by the own weight of the water absorbing device of the present invention, and the air in the water absorbing material is removed, and then the drum. When it is released from the compression again by the rotation of 1, the portion where the air is present is in a depressurized state, so that the breathing water is absorbed in the water absorbing layer 2 made of the water absorbing material due to the negative pressure due to the depressurization and the capillary phenomenon. Will be sucked in.

The water absorbing layer 2 that has absorbed the breathing water is made of the water absorbing material by the pressure from the squeezing roller 7 when it reaches the portion where the squeezing roller 7 is pressed by the rotation of the hollow drum 1. Since the water absorbing layer 2 is compressed, the breathing water sucked in the water absorbing layer 2 is squeezed out again and dropped into the gutter 10. In this step, a part of the breathing water squeezed out as described above passes through the outside of the squeezing roller 7 and drops into the trough 10, while the other part is provided on the surface of the hollow squeezing roller 7. Further, it flows into the hollow inside of the squeezing roller 7 through the large number of small holes 9, 9 ... And then drops again into the gutter 10 through the downward facing portion of the large number of small holes 9, 9. .

Further, since the upper end of the gutter 10 on the drum side is in pressure contact with the water absorbing layer 2 as described above, the breathing water in the water absorbing layer 2 is also in contact with the pressure contacting portion as in the pressing roller. It will be squeezed and will flow into the gutter 10.

At the same time, the upper end of the gutter 10 on the drum side also has a function of scraping off fragments of fresh concrete and mud adhering to the water absorption layer.

As described above, the breathing water flowing into the gutter 10 has its both ends lowered as described above, and flows into the water receiving tanks 4 provided on both sides of the drum 1 at the both ends.

(Other Embodiments) The water absorber described above is configured by one drum having the water absorbing layer 2 around it, but the present invention is not limited to this, and two drums are connected. By using the same structure as the road roller, it is possible to design such that the worker can ride and drive using power.

[0022]

[Effect of device]

 As described above, the present invention has a structure that absorbs breathing water, etc. by the water absorbing layer installed around the drum, so it is most effective for eliminating the breathing water that is shallowly spread over a wide area. In addition, due to the above structure, the whole structure can be made lightweight and inexpensive, and even if the work is performed by placing it on uncured concrete, there is no risk of damaging the fresh concrete.

The one in which the upper end of the gutter on the drum side is in pressure contact with the water absorbing layer helps the water contained in the water absorbing layer to be squeezed out, and at the same time, debris of raw concrete adhering to the water absorbing layer and the like. By also functioning to scrape off mud, etc., it prevents the water absorption capacity of the water absorption layer from being reduced by fresh concrete. The squeezing roller is hollow, and the water absorber of the present invention, which has a number of small holes penetrating the inside of the hollow, has the advantage that the squeezed water effectively drips into the trough by the small holes. It further enhances the effect of squeezing out.
