JPH05272166A - Sewage by-pass device for hume pipe works - Google Patents

Abstract

PURPOSE:To economically avoid noise by completely preventing inflow of sewage so as to conduct works regardless of the flowing water quantity and finishing the work without any sucking up pump in the case of executing a replacement work or newly construction work for a hume pipe, or executing a repair work of any manhole being used and at the time of executing river conservation work. CONSTITUTION:The valve 8 of a circular tube 7 made of rubber such as a tire tube is passed through a hole provided in a suitable position of a circular plate 4, with the polyvinyl chloride tube side thereof first, and the circular plate 4 is clamped from this side and fixed by a nut 9. The vinyl-chloride tube 2 is passed through the circular tube 7 in such a manner as to clamp the circular tube 7 between the circular plates 1, 4. The tube is inserted to a screw head, and the screw head and the thread groove are engaged with each other and turned to a suitable position. The device is installed in a hume tube, and air is fed in the circular tube 7 from the valve 8 of the circular tube 7 until the hume tube and the circular tube 7 or the circular tube 7 and two circular plates 1, 4 completely closely adhere to each other by an air supplier or air compressing cylinder.

Description

Detailed Description of the Invention

[0001]

[Field of Industrial Application] The present invention is intended for replacement work due to breakage of a fume pipe buried underground for discharging domestic waste water, excrement, urine, etc., new construction work, and repair work for human hole in use. When sewage is flowing, the connection between the human hole and the fume pipe cannot be strongly solidified with concrete, mortar, synthetic resin or the like.

Further, when carrying out river construction, it is necessary to prevent the sewage poured into the river along the Hume pipe from flowing into the river construction area. Therefore, in order to avoid this adverse effect, a fume pipe construction wastewater bypass device is installed temporarily.

[0003]

2. Description of the Related Art Conventionally, when replacing fume pipes, performing new construction, or repairing existing human holes, sewage flows in as a method for preventing it from flowing into the construction area. , Submerge the pumping pump in a human hole just before the construction area, raise the pumping hose to the road, extend the pumping hose to the next human hole that passed the construction area, and collect the pumped wastewater from there. It was a flushing method.

[0004]

According to the conventional method, the construction work is carried out at a time when the amount of sewage flowing is reduced, particularly at night and at midnight. As a result, it is not preferable in terms of worker safety and hygiene. Further, if the suction port of the pumping pump submerged in the human hole is blocked by a tree leaf or a plastic bag, the function of the pumping pump will not be fulfilled at all. Then, until the concrete, mortar, synthetic resin, etc. solidify, the generator must be started and the motor of the pumping pump must be rotated day and night, which is not preferable from the viewpoint of resources and noise.

As a result of the above-mentioned problems, by installing this device, even if a large amount of dirty water increases, it is possible to completely prevent the inflow into the construction area and to use a pump for pumping. It can be made to flow through the construction area through the vinyl chloride pipe 2 for bypassing sewage. Therefore, it is possible to work in the daytime regardless of changes in the amount of running water, without having to work at night or at midnight. In addition, this device can withstand repeated use, is economical, does not generate noise, and can be easily assembled and installed as compared with the case of using the pumping pump.

[0006]

According to the constitution of the present invention for solving the above-mentioned problems, a valve 8 of a rubber circular tube 7 such as a tire tube is provided with a circular plate according to claim 2. 4 is passed through the hole 6 provided at an appropriate position from the side having the vinyl chloride pipe 5, and the circular plate 4 is sandwiched from the front side and fixed by the nut 9.

Then, the vinyl chloride pipe 5 of claim 2 is passed through the vinyl chloride pipe 2 of claim 1 so that the circular tube 7 is sandwiched between the circular plates 1 and 4 of claims 1 and 2. Then, when it is inserted up to where the screw thread 3 of claim 1 is,
The thread 3 of claim 1 and the thread groove 11 of claim 2 are engaged with each other and rotated to an appropriate position. This is installed in the fume tube.

[0008] In this state, air is introduced from the valve 8 of the circular tube 7 by an air inlet or an air compression cylinder. If the air pressure in the circular tube is low, it may not be able to withstand the water pressure of the sewage flowing in, or it may cause water leakage from this device. Air is introduced into the circular tube 7 until the circular plates 1 and 4 are completely in close contact with each other.

After fixing, connect a vinyl chloride pipe or the like with a socket and extend it to a position not involved in construction.

[0010]

The device constructed as described above is installed in the fume pipe at a position where it is desired to prevent sewage from flowing into the construction area. In that state, the vinyl chloride tube 2 at the center of the device
This device has an effect that the level of the sewage gradually increases to the position of, so that the sewage naturally flows into the vinyl chloride pipe 2 of the device and passes through the vinyl chloride pipe 2 to pass through the construction area.

[0011]

EXAMPLES Vinyl chloride pipes 2, 5 according to claim 1 and claim 2
Does not cut the thread 3 and the thread groove 11. Then, as shown in FIG. 11, two circular plates 1 and 4 are provided with a plurality of holes through which the anchor bolts 14 pass. A packing 15 is inserted into the shaft of the anchor bolt 14 so that dirty water does not leak from the holes provided in the circular plates 1 and 4.

As shown in FIG. 12, the valve 8 of the circular tube 7 is passed through the hole 6 provided in the circular plate 4 at an appropriate position from the side having the vinyl chloride pipe 5 and fixed by the nut 9. Then, the vinyl chloride pipe 5 is passed through the vinyl chloride pipe 2 so that the circular tube 7 is sandwiched between the circular plates 1 and 4. Then the circular plate 1
The anchor bolt 14 containing the rubber packing 15 is passed from the side without the vinyl chloride pipe 2, and after passing through the circular plate 4, lightly temporarily fix it with the nut 13 from the front side. This is also referred to as multiple locations. The nut 13 corresponding to the anchor bolt 14 is preferably a wing nut that can be easily tightened by a worker. Then, the circular tube 7 is filled with air to some extent. In this state, install the nut 13 that was installed in the fume tube where you do not want to put dirty water and temporarily fix it until the circular tube 7 and the fume tube, and the circular tube 7 and the circular plates 1 and 4 come into close contact with each other. Go

As described in claim 3, the rubber circular tube 7 is not sandwiched between the two plates 1 and 4, but the rubber circular tube 7 is used.
A vinyl chloride tube 10 is inserted into this, and air is introduced from the valve 8 of the circular tube 7 until the circular tube 7 and the fume tube and the circular tube 7 and the vinyl chloride tube 10 are completely adhered. However, in this case, it is preferable that the rubber has a little thickness on both side surfaces of the circular tube 7 made of rubber. Although the same effect can be obtained with the above-mentioned configuration, in this case, the expectation is limited only to the fume pipe with a small amount of sewage flowing.

[0014]

EFFECTS OF THE INVENTION The present invention provides the following by using this device when replacing fume pipes, newly constructing, repairing human holes that are in use, or when performing river construction. effective.

Conventionally, the construction was carried out at a time when the amount of sewage was reduced, especially at night and at midnight. However, by installing this device, the inflow of sewage can be completely prevented and the amount of sewage flowing can be related. You can work without it. Therefore, daytime labor is possible.

Conventionally, a pumping pump has been used until concrete, mortar, synthetic resin, etc. have solidified. However, by installing this device, it is not necessary to use the pumping pump. Therefore, there is less noise than when using the pumping pump, and it is economical in terms of resources.
