Description

  The present invention relates to a temporary merging septic tank attached to a site office used for construction work or civil engineering work, or a temporary building for disaster emergency response, and there is no need for excavation work at the time of installation. The present invention relates to a temporary merger septic tank that can be used safely even if the installation environment is changed.

  As this type of temporary merger septic tank, for example, there is one using a normal burying method. That is, at the time of installation, the site is excavated, a concrete foundation is provided, a merged septic tank is buried, and the surroundings are refilled after piping wiring. At this time, the remaining soil is treated in some way. At the time of removal, it will be digged up after paying attention to avoid damaging the combined septic tank after removing it, and removed after removing the pipe wiring. At this time, soil that is insufficient by some method is prepared, and the area where the combined septic tank is installed is completely backfilled and restored.

  In addition, there is a method using a ground installation method. In other words, a concrete foundation is provided on the ground, and the combined septic tank is installed and fixed by a technique that prevents the fall from occurring. In addition, the inflow pipeline from the drainage source to the merged septic tank is provided with a downward slope so that filth, sewage, and miscellaneous drainage flow down naturally. On the other hand, the position of the inflow pipe immediately before the merged septic tank is quite low, and it is necessary to separately provide a device called a raw water tank between the merged septic tank and the inflow pipe in order to pump the waste water by this height difference. .

  The raw water tank used in the ground installation method is composed of a tank, a submersible pump for filth sewage pumping, and a liquid level sensor, and two units of sewage sewage pumping water based on the amount of liquid in the tank detected by the liquid level sensor. The pumps are operated alternately, and it is necessary to embed them in the ground. It is also necessary to provide a scaffold around the upper manhole in the merged septic tank and to provide a ladder or the like for allowing workers to climb on the scaffold so that inspection and cleaning in the merged septic tank can be performed. According to this construction method, only the raw water tank installation part is excavated as compared with the above-mentioned underground installation method, and there is no need for excavation enough to embed the entire merged septic tank. The construction period can be greatly reduced.

  Furthermore, as a form in which the above-mentioned ground installation method is developed, there is an example in which the septic tank is a ground-type unit as disclosed in Patent Document 1. This is because the control panel for controlling the alternate operation of the merged septic tank, the raw water tank, the pressure feed line connecting the merged septic tank and the raw water tank, and the submersible pump for filthy wastewater in the raw water tank in a box-shaped housing like a unit house. It is fixed. Furthermore, inspection scaffolds, ladders, patrol lamps as raw water tank abnormality alarm devices, etc. can be added, and by installing all the necessary equipment for the septic tank, the entire housing can be installed or removed. It is possible to do. According to this ground type unit, the speed and ease of installation and removal are greatly improved as compared with the above ground installation method.

  The temporary merging septic tank must be used for a limited time and must be used repeatedly for several different sites, so all of the conventional buried installation method, ground installation method, and ground type unit are excavated. There were issues such as the need for work.

  First of all, although there is a merit that after the installation is completed, the underground installation method can effectively use the ground of the space where the combined septic tank is installed, it is necessary to install it for a limited time in order to perform full-scale excavation work. In addition, too many people, heavy machinery, and construction periods are required for removal. Moreover, it cannot respond when another important buried object exists in the basement of the installation space in advance. Furthermore, since it is necessary to discard the piping of the buried portion, waste is generated and the environmental load increases.

  In addition, the ground installation method and the ground type unit require less excavation for the raw water tank than the buried installation method. For this reason, even when excavation is not necessary in other processes, heavy machinery and manpower relating only to excavation work for the raw water tank are generated, and the construction period increases accordingly. Also, depending on the location, there may be cases where it is not desired to perform any excavation such as asphalt pavement or concrete pavement.

  In addition, when installing a combined septic tank that can be reused for temporary use, the installation environment is constantly changed, so the amount of domestic wastewater is also expected to increase or decrease significantly depending on the environment of the land where it is installed. Therefore, the combined septic tank used for temporary construction is desired to be used safely in any environment.

  Therefore, the present invention has been devised to solve the above-mentioned problems, and there is no need for excavation when installing a combined septic tank for temporary use, just like assembly houses such as unit houses and prefabricated houses. The purpose is to provide a temporary combined septic tank that is easy to install, can be disassembled and moved after use, and can be used safely even if the amount of domestic wastewater changes due to changes in the installation environment of the reuse destination To do.

  In order to achieve the above object, the first means in the present invention is to divide the domestic wastewater drainage channel into a plurality of channels in a temporary combined septic tank installed in various assembly houses including unit houses and prefabricated houses. The forced forced drainage in-line pump 4 that is arranged for each flow path and feeds the domestic wastewater to the combined treatment septic tank main body 2, the failure alarm device 6 that issues an alarm when the forced feed drainage inline pump 4 fails, and each pressure feed And a comprehensive operation control panel 5 for controlling the forced drainage inline pump 4 and a general operation control panel 5 for controlling the failure alarm device 6. The pumping unit 3 for pumping up sewage is configured so that the pumping unit 3 for pumping up sewage Accordingly, the overall control of each pump is performed.

  In the second means, the sewage pumping unit 3 and the merged septic tank main body 2 are housed in a housing 1, and the sewage pumping unit 3 can be expanded and contracted, and the flexible pump 10 for ventilation and the flexible for ventilation. The pipe 12 is attached, and the sewage pumping unit 3 is attached to the guide rail 8 attached in the housing 1 so as to move up and down.

  According to claim 1 of the present invention, the forced drainage in-line pump 4 that divides the drainage flow path of domestic wastewater into a plurality of systems, and is sent to the septic tank main body 2 disposed for each flow path, and the forced pumping Pumping for pumping up sewage, comprising a fault alarm device 6 for issuing a warning when the drainage inline pump 4 is faulty, and a general operation control panel 5 for controlling the control of each pumping forced drainage inline pump 4 and the fault alarm device 6. The unit 3 is configured so that the pumping unit 3 for pumping up sewage is configured to perform overall control of each pump in accordance with the amount of domestic wastewater, so that the load on one pump can be distributed. Even if the amount of domestic wastewater changes with changes in the installation environment, it can be used safely. Moreover, it contributes to extending the life of each pump.

  In the unlikely event of a failure, the failure alarm device 6 informs the user, and at the same time, the operation with a normal pump excluding the failed pump can be continued, and the function can be maintained until maintenance, replacement, and repair. . As a result, safe use is possible even when the installation environment is changed. In addition, when a malfunction of the pump occurs due to a failure, it is promptly transmitted to the user, and at the same time, the integrated operation control panel automatically switches the failed pump to the normal pump so that there is no inconvenience to the user. Yes. Furthermore, the same applies to the replacement and maintenance of the failed part, and the pump can be removed without stopping the use of the sanitary equipment on the building side.

  As in claim 2, the pumping unit 3 for pumping up sewage and the septic tank main body 2 for merging treatment are housed in a casing 1, and a pumping flexible pipe 10 that can be expanded and contracted in the pumping unit 3 for pumping up sewage and a flexible for ventilation. The pipe 12 and the sewage pumping unit 3 are mounted on the guide rail 8 mounted in the casing 1 so as to move up and down, so that depending on the site where the casing 1 is installed, The height can be adjusted very flexibly, and it can be installed as close to the ground as possible. Moreover, since the sewage pumping unit 3 and the merged septic tank main body 2 can move together with the casing 1, they can be transported without disposing of any internal piping at the time of installation or removal. Therefore, as with assembly houses such as unit houses and prefabricated houses, it is easy to install and can be disassembled and moved after use.

  As described above, according to the present invention, there is no need for excavation when installing a combined septic tank for temporary installation, and it is easy to install and disassemble and move after use, as with assembly houses such as unit houses and prefabricated houses. It was possible to achieve the original purpose, such as safe use even if the amount of domestic wastewater changes with changes in the installation environment of the reuse destination.

  Embodiments of the present invention will be described below. The temporary merging septic tank of the present invention adds a rapid sewage treatment capacity to an assembly house P such as a unit house or a prefab house installed on land where the sewer is not maintained (see FIG. 2). Therefore, the temporary merging septic tank of the present invention has the merging treatment septic tank main body 2 and the sewage pumping pumping unit 3 installed in the casing 1 so as to be movable together with the casing 1 and the position of the sewage pumping pumping unit 3. Is configured to be supported in a vertically movable manner.

  This pumping unit 3 for pumping up sewage is a unit including a pumping forced drainage in-line pump 4, a failure alarm device 6, and a general operation control panel 5. That is, the forcible drainage in-line pump 4 is a pump that branches the drainage flow path of domestic wastewater into a plurality of systems, and is arranged for each flow path to supply water to the domestic wastewater merger processing septic tank body 2.

  Moreover, the failure alarm device 6 issues an alarm when the pressure-feeding forced drainage inline pump 4 fails, and the general operation control panel 5 performs overall control of the failure alarm device 6 and each of the pressure-feeding forced drainage inline pumps 4. It is configured as follows. Then, the pump 3 for pumping up sewage is configured to perform overall control of each pump according to the amount of domestic wastewater.

  Further, the sewage pumping unit 3 and the merged septic tank main body 2 are housed in the housing 1 so that the sewage pumping unit 3 is moved up and down on the guide rail 8 mounted in the housing 1. Wearing. The sewage pumping unit 3 in the illustrated example is fixed up and down freely by a guide rail 8 through a supporting square steel pipe 9 and a roller 19 (see FIG. 5). And if the fixing bracket for transportation with respect to the pumping unit 3 for pumping up sewage is removed, it can be lowered to the ground. At this time, the pumping unit 3 for pumping up sewage is equipped with a flexible pumping pipe 10 that can be expanded and contracted and a flexible pipe 12 for ventilation. Therefore, the displacement in the vertical direction is absorbed by the pressure-feed flexible pipe 10 and the ventilation flexible pipe 12 (see FIG. 3).

  Further, a branching / inverting branch mass 11 for ventilation and inspection is arranged in the flow path before the sewage pumping unit 3 branches. Then, ball valves 18 are respectively provided in the flow paths branched from the ventilation / inspection branch inverted mass 11. In the example shown in the figure, there are two forced-feed drainage in-line pumps 4 for pumping up sewage, a branching invert mass 11 for ventilation and inspection, a square steel pipe 9 for support, a pipe 16 for pressure-feed pipe confluence, a check valve 17 and a pump replacement. It is comprised by the valve | bulb 18, and wastewater is made to flow into a septic tank using this pumping forced drainage in-line pump 4 (refer FIG. 5).

  The general operation control panel 5 controls the overall control and the failure alarm device 6 of each forced-feed forced in-line pump 4. For example, the ball valve 18 is controlled by detecting the operation status of the forcible forced drainage in-line pump 4. The illustrated general operation control panel 5 performs power reception from the primary power source, power distribution to each electronic device, and various controls of the forced-feed forced drain inline pump 4. In normal control, which pump is to be controlled is controlled by a timer, and when there is an inflow exceeding the performance, other pumps are also moved in parallel to cope with the inflow of large volumes of sewage. When the inflow stops, the operation is automatically stopped (see FIG. 7).

  In addition, if the forced pumping drainage inline pump 4 stops or breaks down due to some trouble, the general operation control panel 5 receives a failure signal and automatically starts operation of other normal pumps. 6 transmits the failure to the user (see FIG. 8).

  On the other hand, the supporting square steel pipe 9 that supports the pumping unit 3 for pumping up the sewage is in contact with the guide rail 8 by means of the rollers 19 and prevents moving to a flat surface while maintaining the degree of freedom in the vertical direction. 3 is prevented from falling off. Connect to the sewage inflow pipe using a flexible joint. Even if the housing 1 is suspended with the transport fixtures removed, the roller 19 comes into contact with the floor of the housing 1 to prevent accidental dropping of the pumping unit 3 for pumping up sewage (see FIG. 6). ).

  The casing 1 is provided with an aeration, backwash air pump 7, a general operation control panel 5, and a failure alarm device 6. The system contains a container for the entire system during transportation, maintains the functions of the septic tank main body during operation, and detects abnormalities. It has a role to inform (see FIG. 3). Thereby, after operating once, operations other than legal maintenance are performed fully automatically to maintain the purification capacity of the septic tank. Its function lasts as long as power lasts. In addition, when a pump abnormality occurs, the user is informed of the alarm function.

  The merging treatment septic tank main body 2 is provided with various pipes for transferring sewage, venting, aeration, and discharge, and each casing 1 can be moved as it is without discarding the pipes during transportation. (See FIG. 3).

  An inspection panel 14 is provided on the inflow side of the housing 1 and can be easily removed. In addition, the inflow surface housing lower beam 13 at the lower part is normally arranged at the lowermost part, but for the convenience of making the pipe close to the ground, the sewage inlet 15 and the target pipe can be connected to a position. The design has been raised. (See Figure 4)

  In addition, this invention is not a thing limited to the example of illustration, Each structure of the merger processing septic tank main body 2 of this invention, the pumping unit 3 for pumping up sewage, etc. can be freely changed in the range which does not change the summary of this invention. Is. Moreover, the structure of the housing | casing 1, an alarm device, a control panel, the flexible pipe 10 for pressure feeding, the flexible pipe 12 for ventilation | gas_flowing, etc. can be set arbitrarily.
