Description

  The present invention relates to an underground storage tank design support device, an underground storage tank design support method, an underground storage tank design support program based on the design method, and a program recording medium recording the program.

  In a residential area or the like, there is a risk that a large amount of rainwater or the like may be accumulated due to heavy rain, etc., and there is a risk that the rainwater or the like may flood the residence. Therefore, in large-scale residential land development sites, conventionally, adjustment ponds have been created at intervals and scales commensurate with the development area. For example, the adjustment pond is formed by digging the ground about 1 m to form a storage portion such as rainwater, and a drainage groove from a surrounding residential area or a side groove of a road is connected to the storage portion. Such ponds can be used to temporarily store excess rainwater during heavy rains, etc. so that rainwater stays in the surrounding residential area, drains into sewage rivers, or rivers resulting from these. It is intended to prevent flooding.

  Moreover, as an adjustment pond, there exists a thing using the osmosis | permeation type storage part comprised so that rain water etc. may be osmose | permeated gradually to the ground by forming the circumference | surroundings of the storage part with a water-permeable sheet | seat. Thus, by forming the wall surface of the storage portion with a waterproof sheet, forming with a water permeable sheet, or forming the bottom with a waterproof sheet and forming the upper with a water permeable sheet, etc. , Functioning as a storage facility, a permeation facility, or a storage permeation facility.

  There are various types of storage and infiltration facilities such as rainwater as described above. The storage and infiltration facility such as rainwater described in Patent Document 1 forms a tank part by digging the ground, and is filled with a plurality of container-like members arranged vertically and horizontally and vertically from the bottom to the vicinity of the ground line. The upper portion is provided with a covering means. The container-like member is constituted by a bottom portion having a large number of holes and a peripheral side plate, and has a tapered shape that decreases toward the bottom portion.

  In addition, the rainwater storage device described in Patent Document 2 is arranged in a water tank formed by digging the ground, and a synthetic resin filling body having a plurality of support columns is arranged vertically and horizontally, and is stacked and filled up and down. A rainwater storage device having a covering means on the top thereof, wherein a water drainage groove is formed on the bottom surface of the water storage tank, and at least a plurality of water injection holes are provided between the columns of the synthetic resin filling body above. Or a diffuser tube having a large number of exhaust holes. This rainwater storage device has an advantage that it is easy to maintain because it can easily remove the solid content accumulated in the filler.

  However, the storage and infiltration facility described in Patent Document 1 has a mud pool in the inflow part to prevent sand and sludge from flowing into the storage part together with rainwater, etc. Sand or sludge that has passed through the mud pool is deposited on the bottom of the reservoir. The storage portion is filled with container-like members arranged vertically and horizontally and vertically, and it is difficult to remove accumulated sand and sludge. For this reason, when the internal volume of a storage part decreases gradually and the amount of storages, such as rainwater, decreases, and an internal volume becomes extremely small, there exists a possibility that it may not function as a regulation pond. In that case, it takes time to dig up an existing adjustment pond, remove the filling member, clean it, and re-install the filling member, and the cost is high. In addition, if necessary, a new storage and infiltration facility will be created. In that case, there is a problem that new land is required and the effective use of the land is hindered.

  Moreover, since the rainwater storage device described in Patent Document 2 is separately provided with a water spray pipe and a diffuser pipe inside the water storage tank, the configuration is complicated, making the device complicated and costly. is there. And since a sprinkling pipe and a diffuser pipe are located in a water storage tank, there exists a problem that the porosity of a water storage tank falls and the amount of water storage decreases. Further, when the solid content deposited on the filler is removed by the water spray pipe, it is necessary to empty the water storage tank and inject high-pressure water from the water spray pipe.

  Therefore, an underground storage tank having a new structure described in Patent Document 3 has been proposed to solve these problems. The underground storage tank with this new structure guides and collects sand and sludge that flows in along with rainwater, etc. to a specified location, sucks out the accumulated sand and sludge at this location, and cleans the specified location. can do. Therefore, even if sand or the like accumulates in the storage portion after being used for a long time, it can be removed, and therefore the internal volume can be sufficiently secured for a long time.

  The underground storage tank of the above-mentioned new structure is installed in the basement, and the water storage material is fitted and stacked to form a space to form a water storage tank, and the water storage tank is covered with a water shielding sheet or a water permeable sheet. Has a structure. Water storage materials used in this underground storage tank are prepared in a plurality of different shapes, and the above-mentioned underground storage tank is configured by combining a plurality of water storage materials in different shapes. . In addition, each of these multiple types of water-repellent materials is large enough to be carried by hand and has high strength, so that construction work can be performed manually and when the water-repellent materials are stacked, Even if a person sits on the water-absorbing material, it can be stably stacked, so that construction work can be easily performed.

As described above, the underground storage tank having the above-mentioned new structure partially changes the combination of the plurality of types of water-holding materials by adopting a structure configured by combining a plurality of types of water-holding materials. It is possible, and it can comprise so that the space | gap part used as a water storage part may become the maximum, maintaining the intensity | strength of an underground storage tank. Therefore, a space-efficient underground storage tank can be formed.

This is to make it easier for sand, sludge, and the like flowing through the inclined member 22 to flow into the U-shaped groove 28. In addition, although the arrow 35 and the arrow 36 are displayed on the top surface of the main stagnant water unit 40 displayed in FIG.3 and FIG.4, this arrow 35 and the arrow 36 have the indication of the arrow. It is used to indicate the direction of inclination of the inclined member 22 included in the water-stagnation set constituting the water-stagnation unit 40, that is, the direction in which the slope becomes lower. However, such an arrow 35 and an arrow 36 are not displayed on the actual main water leakage unit 40. The configuration of the auxiliary water-spilling unit 41 is partially modified from the configuration of the main water-spilling unit 40 described above based on the installation conditions for the underground storage tank.

  Further, as described above, the water storage tank 50 of the above underground storage tank is a manhole unit for sucking sand or sludge accumulated in the U-shaped groove 28 with a vacuum or the like and cleaning the U-shaped groove 28. 45 is provided. The manhole unit 45 has the same main body size as the main stagnant water unit 40 and the sub stagnant water unit 41 except for the portion exposed to the ground surface. It can be replaced. Therefore, at the design stage, after the main water-spilling unit 40 and the sub-water-spilling unit 41 are arranged to form the water-spilling tank 50, a part of the main water-spilling unit 40 or the sub-water-spilling unit 41 is replaced with the manhole unit 45. By doing so, the manhole unit 45 is arranged.
