Description

[Detailed Description of the Invention] (Industrial field of application) The present invention is an apparatus used to prevent the generation of dust during the construction work in which a relatively large structure such as a concrete structure is destroyed and demolished. It is about.

(Problems to be solved by conventional techniques and devices) In recent years, in destroying a building for dismantling, various devices have been developed to suppress generation of noise and dust as much as possible. In any case, it is unavoidable that a considerable amount of dust is generated, and therefore, it is necessary to carry out the work while sprinkling water with the hose each time in the destruction and debris work.

This water sprinkling work usually uses an appropriate existing water tank, such as a fixed water tank for storing tap water, which was attached to the building to be demolished, that is, a tap water tank, and Make a foundation by arranging timbers etc. on the water tank, attach a boosting pump on it and connect a hose to its discharge pipe,
It is carried out manually by holding this hose tip.

However, preparing a water tank and a pump each time to make a sprinkling facility requires extra work setup, and it takes time to open and close the water supply cock for the water tank. Since priming water is required each time the engine is started, it takes a considerable amount of labor and time to supply water at the time of starting.

(Means for Solving the Problems) On the other hand, in the present invention, a water tank and a power chamber are juxtaposed on one base frame, and a pump and various auxiliary equipment are arranged in this power chamber to form an integrated structure. The water supply to the water tank is always performed at a constant water level with an automatic valve, and the pump does not require priming and can be started immediately to improve work efficiency.

(Embodiment of the Invention) An embodiment of the present invention will be described with reference to the drawings.

In the figure, 1 is a water tank, 2 is a power chamber, which are arranged side by side on a common base frame 3. The water tank 1 is made in the shape of a metal box, and a float valve 5 connected to the water supply pipe 4 is attached to one corner of the upper edge. Has become.

The power chamber 2 is formed in a box shape having a height equal to that of the water tank 1, and the interior is partitioned to accommodate the cord 6 to be connected to the power source and tools such as a wrench in the upper stage, and the lower stage in the lower stage. The floor accommodates a booster pump 7 such as a multi-stage turbine pump, a motor 8 directly connected to the booster pump 7, and a reel 10 around which a long hose 9 is wound. The suction port 11 of the booster pump 7 is directly connected to the lower end of the water tank 1, and the upper end of the discharge port 12 is connected to one end of the hose 9 via an opening / closing valve 13. The front side of the power chamber 2 is formed as an opening / closing door, and the other side is formed as a detachable wall plate made of a perforated plate so as to have a structure convenient for inspection and repair of the pump and motor and for putting in and taking out each member. It is preferable. Further, a generator with an engine is housed in the power supply cord 6 housing portion in the upper stage.

(Operation and effect) The present invention is configured as described above and is transported to a dismantling construction site, the tip of the water supply pipe 4 is connected to a water pipe to supply water into the water tank 1, and the reel 10 in the power chamber 2 is connected. By simply taking out the hose 9 and connecting an appropriate nozzle to the tip of the hose 9, the sprinkling work for dust prevention can be performed. In this case, as described above, since the water supply pipe 4 connected to the water pipe is provided with the float valve 5, the water supply to the water tank is automatically stopped when the water level in the water tank 1 becomes full,
Problems such as opening and closing by hand or draining away as in the past are eliminated, and since the suction port 11 of the booster pump 7 is connected to the lower part of the water tank 1 and the inside of the pump is below the water level, priming is not required Since the water can be started immediately and the water level in the water tank 1 is stable, smooth water can be sent to a considerable height.

As described above, the present invention can perform required watering in a space as small as possible simply by installing it on the construction site, fill the water tank in advance, and load the generator as described above and transport it. By doing so, it can be used even in places where it is difficult to secure water supply and power supply. Furthermore, since mechanical equipment such as pumps and motors are isolated in the power room 2, the risk of noise and contact during operation is prevented, and the reel 10,
There are many advantages such as keeping the cord 6 and each tool always tidy.
