Description

{The balance control device for the sewage disposal sewage disposal tank}

The present invention relates to a septic tank for treating domestic sewage or excrement that is discarded after being used for a certain purpose in homes or industrial sites. More specifically, a precast balance control device is installed in the soil layer at the location of the septic tank to be installed on soft ground or wastewater. In addition to preventing sinking of the septic tank due to dynamic load, the septic tank can easily adjust and control the omnidirectional vertical/horizontal balance during the initial installation process of the septic tank, and absorbs and buffers external forces such as shock or shaking such as earthquakes. Of course, it is about a balance control device for a sewage treatment septic tank that prevents deformation and damage of the connection between the sewage inflow and outflow pipes and the drain pipe body.

As is well known, if domestic sewage (feces or sewage) discharged from large-scale buildings, houses, or various facilities is discharged into rivers or the sea, it becomes the root cause of water pollution, so it must be purified and treated before discharge, and such purification is required. A representative device for treatment means is a septic tank.

Depending on the treatment capacity, a typical sewage septic tank can be divided into a tank-type septic tank made of synthetic resin made of FRP or polyethylene (PE) or an enclosure-type septic tank poured with concrete. After excavation work is performed in advance, a sewage septic tank (1) is buried inside the ground, and an inlet pipe (2) for introducing domestic sewage into the upper end of one side is protruded and the purified domestic sewage is discharged to the upper end of the other side. An outflow pipe (3) is formed to discharge the inlet pipe (2) and the outlet pipe (3), respectively, are connected to the drain pipe (4) (4a), and a ventilation port (5) is provided to discharge the internal odor into the atmosphere. This is installed.

In addition, between the inlet and outlet pipes of the septic tank, multi-stage treatment tanks (septic tank, contact aeration tank, sedimentation tank) for purifying and treating domestic sewage are sequentially partitioned through partitions, and domestic sewage flowing into the septic tank is formed sequentially. The sewage is decomposed (anaerobic decomposition) through anaerobic bacterial action in the septic tank (6) and then flows into the contact aeration tank (7), and organic substances are secondary from the contact member (contact filter in which aerobic microorganisms are cultured) installed inside the aeration tank. After being decomposed and removed, the final sludge (sludge) is precipitated and removed while passing through a sedimentation tank (8) equipped with a crushed stone layer, and the domestic sewage that has undergone a series of purification treatment steps is collected into the manhole (9) along with rainwater. It is then discharged into rivers or the sea to prevent water pollution.

Representative prior documents for the above-mentioned sewage septic tank include Korea Patent Publication No. 10-0877964 to Korean Patent Publication No. 10-2069053, etc. These sewage septic tanks are divided into treatment tanks using partition plates. Although it is a structure suitable for purifying domestic sewage through sequential treatment stages, if it is buried in an area where the stability of the stratum is low, such as soft ground, it will be greatly affected by the load of the ground structure added to the own weight of the heavy septic tank. This causes the septic tank to sink and flow, which causes the septic tank inlet and outlet pipes to separate from the drain pipe, causing environmental problems such as groundwater contamination and odor generation due to external outflow of domestic sewage.

In addition, when a septic tank is buried on a slope such as a steep slope, it is not easy to adjust the balance in the horizontal or vertical direction, so installation stability is not good, and workability is reduced as workers must repeat the work of smoothening the buried surface several times. In addition to the problem of extending the construction period due to delays in the connection installation of the septic tank inlet pipe, outlet pipe, and drain pipe, there is no means to absorb and buffer shaking or shock, so the septic tank and the septic tank are protected from strong physical external forces such as earthquakes. It is difficult to avoid deformation and damage to the pipe connection area, and various problems such as clogging of foreign substances in the connection area of the pipe body (inflow pipe, outflow pipe, drain pipe) occur.

(Prior document 0001) Republic of Korea Patent Publication No. 10-0877964 (registered on January 5, 2009) (Prior document 0002) Republic of Korea Patent Publication No. 10-2069053 (registered on January 16, 2020)

The present invention was developed to efficiently improve the conventional problems as described above, and consists of an anti-sink plate that distributes the load on the bottom of the septic tank, a support and support holder that serves as a seat, and a buffer member that absorbs shock. The purpose is to fundamentally prevent septic tank settlement by installing a combined balance control device, as well as to prevent deformation or damage to the septic tank and connecting pipe accessories even from physical external forces such as earthquakes.

Another object of the present invention is to attach an opposing elevating leveler to the support holder of the balance control device to easily and immediately adjust the balance in the vertical or horizontal direction according to site conditions during the installation of the septic tank. Another feature is that the septic tank installation stability and workability are further improved.

In addition, the present invention connects the pipe body (inlet pipe, outlet pipe) of the septic tank and the drain pipe with an elastically deformable carbon fastening pipe, so that even in the event of strong physical external forces such as shaking, impact, or twist or ground subsidence, the pipe connection portion may be separated or separated. Another purpose is to prevent the outflow of domestic sewage by preventing deformation and damage, and to fundamentally prevent clogging by foreign substances due to deformation.

In order to achieve the above-mentioned object, the present invention protrudes an inlet pipe for introducing domestic sewage at the top of one side, and an outlet pipe for discharging purified domestic sewage is formed at the top of the other side, and these inflow pipes and discharge pipes are formed at the top of the other side. Each pipe is connected to a drain pipe and in a septic tank that is installed underground, a balance control device is installed at the bottom of the septic tank burial location so that the septic tank is placed on it, and the balance control device is plate-shaped. An anti-sinking plate is formed, and the support holder part and the support holder part are integrally protruded on top of it. Elevating levelers are installed on both ends of the support holder part to adjust the vertical/horizontal balance of the septic tank, and the support holder part is formed to protrude as one piece. A plurality of buffering members are installed on the upper surface of the support holder and the support holder to absorb and buffer vibration or shock transmitted to the septic tank, and a vibration dispersion guide is fastened in connection with the support holder and the support holder. A feature of the technical configuration is that the inlet pipe, the outlet pipe, and the drain pipe are connected by a carbon fastening pipe.

In addition, the elevating type leveler of the present invention has a flat rectangular shape with at least two fastening holes spaced apart from each other on one side, and is guided and lifted up and down within an insertion fastening portion on the outer peripheral surface of the support holder portion. It is fastened using a plurality of fastening nuts and fixing bolts installed embedded in the buffer, and the buffer member is made up of a compression spring and a pocket part, and a plurality of fitting grooves at regular intervals are formed on the upper surface of the support holder part and the support holder part. Another feature of the technical configuration is that one end of the cushioning member is fitted and the length of the cushioning member mounted on the support holder portion is longer than the length of the cushioning member mounted on the support holder portion.

In the present invention, the sinking flow of the septic tank is prevented by the anti-sink plate of the balance control device, so installation stability is improved and product life can be expected to be extended by preventing deformation of the multi-stage treatment tank, and the inlet and outlet pipes of the septic tank By preventing deformation, separation, or damage to the connection part of the drain pipe, it provides the effect of fundamentally blocking water pollution caused by domestic sewage outflow.

In addition, the present invention can easily and immediately control the vertical/horizontal balance adjustment according to the site conditions of the ground layer during the installation process of the septic tank, thereby improving septic tank burial workability, shortening the construction period, and reflecting the seismic design. Through this, various benefits are obtained, such as protecting the septic tank from strong external forces such as earthquakes and ensuring quality stability.

It is based on a rectangular plate-shaped anti-sink plate (10) and has a support holder portion on it. (20) (30) and the support holder portion (40) are protruded and molded as one piece. Here, the above-mentioned support holder parts (20) (30) and support holder parts (40) have a hemispherical upper surface so that the cylindrical septic tank is stably placed, and the support holder parts (20) (30) are one set. It is formed to face both ends of the upper surface of the anti-sink plate 10, and the support holder part 40 is positioned in a spaced apart state between a pair of support holder parts, and the height of the support holder parts 20 and 30 is The support holder part 40 is configured to have a lower height, and a plurality of fitting grooves 21, 31, 41 are formed at regular intervals on the support holder part and the upper surface of the support holder part, which will be described later. One end of the buffer member (50) (50a) is fitted and installed.

In addition, the vertical/horizontal balance of the septic tank (1) is adjusted by mounting elevating levelers (60) (60a) on both ends of the support holder parts (20) and (30) in the example above, and the support holder part (20) ) (30) and a plurality of buffering members (50) (50a) are installed on the upper surface of the support holder portion (40) to absorb and buffer vibration or shock transmitted to the septic tank, and the support holder portion (20) (30) ) and the support holder part 40 so that the vibration dispersion guide 70 is fastened, and the inlet pipe 2, the outlet pipe 3, and the drain pipe 4 (4a) of the septic tank 1 are connected to the vibration dispersion guide 70. It is configured to be connected by a bullet fastening pipe (80).

The anti-sink plate 10 according to a preferred embodiment is in the form of a rectangular plate and has a plurality of drainage holes 11 penetrating the upper surface at regular intervals, so that rainwater seeping into the ground does not accumulate in the anti-sink plate 10. Natural drainage is encouraged, and a plurality of press-fitting protrusions (12) are formed to protrude downward from the bottom surface of the drainage hole (11) to effectively prevent the flow of the anti-sink plate.

The elevating leveler (60) (60a) of the illustrated embodiment is pressed and formed into a flat rectangular shape using a metal material, and at least two fastening holes (61) (61a) are formed through and spaced apart on one side, In the above example, a plurality of fastening nuts (23) (33) are inserted and guided into the insertion fastening portions (22) (32) formed on the outer peripheral surface of the support holder (32) and lifted and installed, and are embedded in one side of the insertion fastening portions (22) (32). It is fastened and mounted using fixing bolts (24) and (34). In addition, rectangular guide grooves 25 and 35 are vertically formed on both sides of the insertion fastening portion, and corresponding guide portions 62 and 62a are protrudingly formed on both sides of the elevating leveler to form these (guide grooves, guide The combination of parts) allows the elevating levelers (60) (60a) to move up and down smoothly without being separated from the insertion fastening portions (22) (32).

The buffer members (50) (50a) of the city are composed of a combination of compression springs (51) (51a) and pocket parts (52) (52a), and the pocket parts (52) (52a) are made of soil, sand, or It is formed in the form of a bag using synthetic resin fabric as a means to block fine pebbles, etc. from flowing into the compression springs (51) (51a), and the support holder parts (20) (30) and the support holder parts (40) in the above example. ) The lower end is inserted and fastened into the fitting grooves (21) (31) (41) formed on the upper surface, and the support holder portion (40) is longer than the length of the buffer member (50) mounted on the support holder portion (20) (30). ) The length of the buffer member (50a) mounted on is formed to be long.

The buffer members (50) (50a) in the example above are in contact with the lower outer peripheral surface of the septic tank (1), and when a physical external force such as vibration is transmitted to the septic tank, the buffer members (50) (50a) absorb and buffer the vibration, causing deformation of the septic tank itself or the connecting pipe ( It is a component to prevent separation or damage of the inlet pipe, outflow pipe, and drain pipe), and the length of these buffer members (50) (50a) is differentially applied according to the installation object (support holder portion, support holder portion) to provide buffering power. The buffering support force and the shock absorbing force are efficiently combined, and the buffering member 50 disposed on the upper surface of the support holder portion 20 and 30 is compressed into a strong elastic state on the lower outer peripheral surface of the septic tank 1 and is used by the neighboring lifting leveler. (60) Together with (60a), it is designed to support and induce the septic tank (1) to be stably placed and fixed, and to exert a buffering action in response to strong vibration, and the buffer member (50a) located on the upper surface of the support holder portion (40) Gently contacts the lower outer peripheral surface of the septic tank's central position to delicately and closely absorb and buffer the vibration transmitted to the septic tank (1).

The carbon fiber fastening pipe 80 of the illustrated embodiment is double injection molded using a silicone-based soft resin material and a polypropylene or polyethylene-based hard resin material, and includes an inlet pipe (2), a drain pipe (4), and an outlet pipe. It is a component for interconnecting (3) and the drain pipe (4a), and is elastically deformable. This elastic fastening pipe 80 is formed with opposing hard fastening parts 82 and 83 on both sides based on the soft corrugated elastic part 81 at the central position, and the fastening parts 82 and 83 are Insertion grooves (82a) (83a) are formed inside, and fastening fitting portions (82b) (83b) and support fitting portions (82c) (83c) having threads (reference symbols omitted) formed on the outer peripheral surface are insertion groove portions (82a) (83a). ) It is arranged up and down, and watertight packing (82d) (83d) is inserted and installed inside the insertion groove. In response to unpredictable physical external forces such as vibration, shaking, or ground subsidence, the connection between the inlet pipe (2) and the drain pipe (4) of the septic tank (1) or the outlet pipe (3) is connected through the carbon fiber fastening pipe (80) in the example above. ) and the connection portion of the drain pipe (4a) is prevented from being separated or damaged.

In addition, the vibration dispersion induction device 70 according to a preferred embodiment has a function for discharging part of the physical external force (vibration or shaking) transmitted to the sewage septic tank 1 into the inside of the stratum, and the entire balance control device (A). It plays a role in distributing and inducing external forces uniformly across the area, thereby efficiently dispersing and attenuating the external force acting on the septic tank, thereby deforming or damaging the septic tank (1) and the connecting pipes (inflow pipe, outflow pipe, and drain pipe). can be effectively prevented.

The vibration dispersion guide (70) with the above role has a rectangular shape, but it is desirable to use a thin stainless steel core (71) to prevent corrosion and improve elasticity. If necessary, a synthetic resin protective coating layer (71) is applied to the surface of the stainless core. 72) may be formed thickly. In addition, one end of the vibration dispersion guide is inserted into the recessed protrusion part (26) (36) on one side of the support holder part (20) (30) and fastened with a fixing means such as a bolt, and the other end is inserted into the recessed protrusion part (26) (36) of one side of the support holder part (20) (30). After inserting and fastening into the jaw portion 42, ensure that it is fixed with a bolt.

The following explanation is to examine in detail the installation process and effects of the balance control device (A) and the septic tank (1). First, the anti-sink plate (10) is lowered and placed, and then the septic tank (1) is lifted using a device such as a crane and placed on the support holders (20) and (30) on both sides of the anti-sink plate to complete the installation. I do it. At this time, as shown in Figures 5 to 6, the upper surface of the plurality of buffer members 50 disposed on the upper side of the support holder portion is in contact with the outer peripheral surface of the lower side of the septic tank and is strongly compressed and pressed at the same time, and is located at the front and rear of the support holder portion 20 and 30. The upper end of the elevating leveler (60) (60a) is also in contact with the lower outer peripheral surface of the septic tank (1), thereby fixing the septic tank without moving in a stuck state, and the buffer member (50a) located on the upper part of the support holder portion (40) also touches the septic tank (1). (1) It contacts the outer peripheral surface of the lower center in a non-strong elastic state and is gently compressed to elastically support the septic tank.

In this way, both sides of the lower outer peripheral surface of the septic tank (1) are provided with a strong elastic force through the buffer members (50) (50a) located at the support holder portions (20) and (30), and the outer peripheral surface at the central position of the lower side of the septic tank is provided with a support holder. As a not strong elastic force is provided from the buffer member 50a of the part 40, shock can be efficiently absorbed and cushioned according to the complex elastic action of the buffer members 50 and 50a even in strong external forces or weak shaking and vibration. It becomes possible.

In addition, most of the vibration applied to the septic tank (1) is absorbed and buffered through the above-described buffer members (50) (50a), and is organically connected to the support holder portion (20) (30) and the support holder portion (40). Vibration dispersion guide 70 can be used to distribute and attenuate more efficiently. When an external force is transmitted to the sewage septic tank 1, tremors occur while part of the vibration is absorbed by the vibration dispersion guide 70. This ballistic process can quickly radiate and attenuate vibration throughout the stratum, making it an earthquake-resistant function that is very suitable for preventing physical deformation or damage to the septic tank (1) and the connecting pipes (inflow pipe, outflow pipe, and drain pipe). It becomes possible to implement.

In addition, natural drainage of rainwater that seeps into the ground is facilitated through the drainage hole 11 formed in the anti-sink plate 10, and the flow of the anti-sink plate 10 from the downwardly protruding press-in protrusion 12 is efficiently controlled. This ensures the installation stability of the overall balance control device (A).

In addition, the balance in the vertical/horizontal directions can be easily and easily adjusted during initial installation of the septic tank using the elevating levelers 60 and 60a referring to FIG. 7, so that the septic tank 1 can be moved in one direction. In case of loss of balance and tilt, loosen the fixing bolts (24) (34), release the fixation of the elevating leveler (60) (60a) from the insertion fastening part (22) (32) of the support holder part, and then compensate for the tilt angle. Quickly adjust the balance of the sewage septic tank (1) by raising or lowering the elevating leveler (60) (60a) to an appropriate height, then inserting the fixing bolts (24) (34) into the fastening nuts (23) (33) ) so that the elevating leveler (60) (60a) is fixed at the height adjustment position, so that the septic tank (1) is balanced in the vertical or horizontal direction even in a buried environment such as a steep slope or an uneven installation surface. It can be installed quickly and easily, and the smoothness and compaction process for the buried ground is omitted, which can be expected to improve installation workability. In addition, during the above-mentioned balance adjustment process, the plurality of buffer members (50) (50a) installed on the upper surface of the support holder portion (20) (30) are in close contact with the lower outer peripheral surface of the septic tank to continuously maintain the elastic state, thereby maintaining the balance. Efficient buffering is always possible before or after adjustment, and this balance control can be adjusted in both vertical and horizontal directions through the same process.

The following explanation is to examine the installation process and effects of the carbon fastening pipe.

As shown in Figures 8 and 9, ring-shaped packings (82d) (83d) are inserted into the insertion grooves (82a) (83a) on both sides of the carbon fiber fastening pipe (80), and then inserted into one side of the septic tank inlet pipe (2). Threads formed on the fastening fitting parts (82b) (83b) of the fastening parts (82) (83) with the carbon fastening pipe (80) positioned on one side of the drain pipe (4) or on one side of the outflow pipe (3) and the drain pipe (4a). are screwed to the threads (drawing symbols omitted) of the inlet pipe (2), the outlet pipe (3), and the drain pipe (4) (4a), respectively, to insert pipe bodies (inlet pipe, outlet pipe, drain pipes) are connected to each other, and at this time, the fastening fitting parts (82b) (83b) and the support fitting parts (82c) (83c) are connected to the inlet pipe (2), the outlet pipe (3), and the drain pipes (4) (4a). In addition to being in close contact with the inner and outer peripheral surfaces of ), stable fixation is achieved, and when the septic tank (1) flows from the installation location due to external forces such as ground subsidence or vibration, the wave-shaped expansion and contraction portion (81) at the center of the fastening part moves within the flow range. It acts elastically within the pipe body to fundamentally prevent separation of the connection parts between the pipe bodies (2) (3) (4) (4a), thereby preventing groundwater contamination due to domestic sewage outflow and preventing foreign substances from clogging within the pipe body. This is fundamentally prevented.

The balance control device reflecting the earthquake-resistant design with such a configuration and embodiment can be said to be a new useful invention with improved installation, workability, and stability, and is a technology very suitable as a linked device for the installation of various sewage septic tanks.
