Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sedimentation basin equipped with a sediment scraper, and particularly to means for finishing the bottom of a concrete sedimentation basin.

Figure 1.2 shows a general model equipped with a sediment scraper 1.

The concrete sedimentation basin 2 is shown. The bottom of the sedimentation tank 2 is covered with surface material such as small-grain aggregate concrete or mortar on the surface layer of the pond bottom, which is made of rough concrete, so that the raking flights 3 can be smoothly maneuvered. However, it has been desired to level the surface and make it smooth.

The conventional means for finishing the surface layer 5 is to put it on the bottom of the pond.

The above-mentioned facing material is leveled so as to eliminate voids, etc., and
Next, support for Flight 3 was laid on the bottom of the pond 4.

Using the ruler 7 placed on the ruler 6, level the surface layer 5 with a hand-scraped souffle pad B. Lay the plank 9 on the leveled surface layer 5; Work on board.

10 was struck on the upper surface of the surface layer 5 by a member of staff.

and compact the facing material. Using the gangboard 9 as a foothold, the top surface of this compacted surface layer 5 is smoothed with a trowel 11 to smooth the top surface of the surface layer 5. , when leveling and leveling this into a flat surface.

Incorporating air bubbles or creating voids.

In order to remove air bubbles and voids using a cross-conducting operation, the surface material must be spread over small areas at a time, so manual work is required, making it difficult to keep the difference in height within 5 meters.・As the compaction plates for compacting the surface layer have become smaller and compaction has been concentrated locally, there has been a drawback that the compaction has been uneven and the conditions have been compounded.

This invention can compact the surface layer flatly by eliminating air bubbles and voids (surface material of concrete or mortar) as long as the difference in height is within 5 m, and can quickly finish the bottom of the sedimentation basin. The purpose is to provide equipment for

do.

The purpose of this invention is to compact the surface layer, which has been leveled to a level difference of 5 cm or less with some air bubbles and voids, to flatten the entire surface while crushing the air bubbles and voids.

This is because they are trying to make the finishing process smoother and easier.

The structure of this invention will be explained with reference to figures of embodiments. 1. Fig. 5 shows the plane of this embodiment, Fig. 6 shows its front side,
7 shows arrow view B-B in FIG. 6, ゛FIG. 8 shows arrow view C-C in FIG.
The figure shows arrow E-F in Fig. 5, and the figure 11 shows arrow F in Fig. 5.
-F, which is common to the conventional one, is designated by the same reference numeral as in FIGS. 1 to 4, and its explanation will be omitted. In FIG. 5.6, the supporting/carrying cart 12 is placed on the rail 6 so as to be freely movable,
of this support cart 12.

The compaction device 15 is suspended in the middle, and the front part of the support cart 12 is
Attach the leveling device 14.

The support cart 12 has an intermediate frame 14 and a side frame 1 arranged in parallel.
A spar pipe 16 is fixedly inserted through the front and rear portions of the spar 5. At the front and rear of the side frame 15, there are wheels rotatably mounted via a bearing box 17.

A drive motor 20 is connected to one wheel 18 via a transmission 19, and this drive motor 20 is fixed to the side frame 15. In the middle of the side frame 15, a main screw 22 is screwed and locked into a drop rod 21 that passes through the side frame 15 vertically.゛At the lower end of the hanging rod 21, there is a fastener with the same length as the width of the surface layer 5.

A plate 23 is fixed, and this clamping plate 26 has a groove 23A facing the rail 6 on its lower surface, and a vertical vibrator 241 on its upper surface.
' constitutes the compaction device 13 (the front and rear W of the compaction plate corresponds to the capacity of the vertical vibrator 24 and the required surface pressure for compaction.

selected from. ) The leveling device 25 has an arm 26 protruding forward of the support cart 12 fitted into the girder tube 16, and a hopper 12 with which a covering material press-fitting tube (not shown) communicates with the arm 26.
7 is supported, and the rear wall of this hopper 27 is a scraper plate 2.
The hopper discharge port, which also serves as 7A and opens over almost the gold mine of the surface layer 5, is equipped with an airtight cut gate 2B, and the arm 26 and the cut gate 2B are connected via an opening/closing cylinder 29. .

3・ The operation of each part of the above structure will be explained next.　　　　.

The leveling device 25 sends the pressure-fed facing material to a hopper 27.

When extruded from the surface layer 5, it is uniform throughout the entire surface layer 5.

The upper surface of the surface layer 5 is leveled using the scraping plate 27A, and the facing material is spread on a flat surface with a difference in height of 5 mm or less. The compaction device 16 is used to compact the top surface of the surface layer 5, which has been leveled by the leveling device 14 or other means to a height difference of 5 levels or less, and the compaction plate 2 over almost the entire width.
5, and shake this clamping plate 23 up and down.

When vibrated by the moving device 24, the clamping plate 23
Hit the “, press down on the high part of the surface, and press down.

The air bubbles and voids present in the surface layer 5 are crushed and removed by the impact, and as water content is squeezed out, the fine filler (
(cement, fine sand, etc.) is allowed to ooze out onto the surface to adjust the level of compaction and the base for a smooth finish.

(Incidentally, if you want to remove the intervening air bubbles and voids more quickly, you can also install a plunging device 30 in front of the compaction device 13 to remove the air bubbles and voids and plunge the aggregate deep into the aggregate. 4. As explained above, the present invention uses a clamping plate equipped with a clamping plate and a vibrator that contacts the upper surface of the surface layer, which is leveled with a height difference of less than 5 inches, over the gold plate. For solid equipment.

When you tap the surface layer, it removes air bubbles and voids.

Squeeze out the water, compact the surface layer flat, and prepare the base for a smooth finish.
