Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a construction for storing and infiltrating rainwater or the like in which rainwater is infiltrated into the ground to prevent overflow of sewerage or the like.

[0002]

2. Description of the Related Art When a large amount of rainwater intensively flows into a sewer, it loses its function as a sewer and overflows. As a means for avoiding such a situation, there is a regulating pond, which temporarily stores rainwater, thereby preventing the above-mentioned sewer overflow, and aims for natural penetration of rainwater into the ground. It is for. However, the regulating pond has a problem of securing a site and a problem of management for avoiding danger of a fall accident of a child or the like, and therefore has a significant economic burden on construction and management.

[0003] As means for solving the above-mentioned problems, a "storage and infiltration facility for rainwater or the like" (JP-A-4-26664).
No. 8). This consists of digging down the ground to form a tank part, and a large number of container-like members with water permeability inside,
It is arranged so as to be filled in the front-rear, left-right and up-down directions, and is provided with a covering means at the top.

[0004] The storage and infiltration facility achieves a temporary storage purpose by storing rainwater in a tank portion, substantially in a container-like member arranged vertically and horizontally and vertically, and achieves penetration of rainwater into the ground. It is like that. Thereby, the danger avoidance and effective utilization based on the presence of the covering means are achieved on the tank upper surface, and the problem caused in the regulating pond is solved.

[0005]

In the case of the above-mentioned "rainwater storage and infiltration facility", fine foreign matter such as fine earth and sand contained in the rainwater flowing into the tank accumulates on the bottom surface of the tank to form a container. It can be said that the sediment is embedded or soars based on the flow of the internal storage water, which causes clogging of the inner peripheral wall of the tank and lowers the underground penetration capacity. A problem arose.

The present invention has been made to provide a construction for storing and infiltrating rainwater or the like which has solved the above-mentioned problems.

[0007]

SUMMARY OF THE INVENTION According to the present invention, there is provided a base frame 11 provided with a space at a bottom of a water tank forming recess 10 formed by digging the ground so that a cleaning worker can enter therein. Is installed, and a plurality of partitioned small spaces are connected to each other in the front-rear, left-right, and up-down directions in a state of being connected to each other, and the water storage space forming structure U is connected to the base frame 11. The present invention relates to a structure for storing and infiltrating rainwater or the like which is buried in the ground by applying the burying means 12 using soil covering and the like, while mounting and laminating in a state.

The present invention has solved the conventional problems based on the above-described configuration.

The water storage space forming structure U is, specifically, a base 1 having a communication frame shape.
And two spacer units A comprising a truncated cone-shaped cylindrical portion 2 integrally protruding from the board surface of the base portion 1 and vertically connected with the respective cylindrical portions 2 facing each other. Is defined as one unit, and the unit is connected in required directions, front and rear, left and right, and up and down directions.

[0010]

The structure for storing and infiltrating rainwater or the like according to the present invention is constructed so as to be interposed at a required portion of a sewer. As a result, rainwater flowing from the upstream part of the sewer will flow into the structure according to the present invention and be stored once. Therefore, the stored water is permeated into the ground, that is, permeated into the ground from the inner wall surface of the water tank forming recess.

In the case where a large amount of rainwater flows in and the underground infiltration cannot be made in time, it is released to the downstream side of the sewer by an overflow action. At this time, since the escape water is only the part that cannot be digested due to the above-described infiltration into the ground, the sewer does not overflow.

[0012] With the storage of the rainwater, fine foreign substances contained in the rainwater accumulate in the base frame 11 as sludge. Therefore, after draining the water periodically, a worker is sent into the base frame 11 to remove the sludge artificially. By this, degradation of the underground penetration efficiency due to sludge adhesion is eliminated.

[0013]

FIG. 1 shows a first embodiment of the present invention. In the figure, reference numeral 10 denotes a water tank forming recess formed by digging down the ground, and a base frame 11 having a space enough to allow a cleaning worker to enter therein is installed on the bottom surface thereof. ing.

The base frame 11 is for depositing fine foreign matter (sludge) contained in rainwater, and is provided with necessary reinforcing members 11b such as columns or walls for reinforcing and holding a working space 11a therein. Have been.

U is a structure for forming a water storage space which is placed and laminated on the base frame 11 in a communicating state.
Is to divide a large number of small spaces into front and rear, left and right, up and down,
It is provided with a form that is connected in a state where they are communicated with each other. The specific configuration of the construct U will be described later in detail.

The water storage space forming construct U is
It is completely housed in the recess 11 for forming a water storage tank, and the upper surface thereof is provided with a burying means 12 such as soil covering. That is, the base frame 11 and the water storage space forming construct U
Is designed to be completely buried underground.

The water storage space forming structure U described above is a spacer unit A shown in FIG. 2, that is, a base unit 1 having a communication frame shape, and integrally projecting from the board surface of the base unit 1. A required number of the spacer units A, which are provided with the provided truncated cone-shaped cylindrical body portions 2, are connected to each other as shown in FIG. It should be noted that the number of stacked layers shown in the drawings is merely an example, and the present invention is not limited to this.

Further, the spacer unit A is composed of two units which are vertically connected to each other in a state in which the cylindrical portions 2 are opposed to each other, and is used as a required unit, in the front and rear, left and right, and vertical directions. The water storage space forming construct U is formed by the connection. The formed structure U for forming a water storage space has a configuration in which the cylindrical body portion 2 functions as a spacer column, and a large number of spaces that communicate with each other are partitioned by the communication frame-shaped base portion 1. Will be presented.
Then, by adopting such a configuration, the water storage space forming construct U exhibits strong resistance to a pressing force from above.

Reference numeral 13 denotes a water permeable sheet, which penetrates rainwater from the inner wall of the water tank forming recess 10 by covering the four peripheral wall surfaces of the water tank forming recess 10 and, if necessary, the bottom surface thereof. At this time, it plays a role of collapsing earth and sand on the inner wall surface or removing foreign substances in rainwater. However,
The water-permeable sheet 13 can be omitted from the embodiment.

The bottom surface of the base frame 11 described above is preferably a flat floor surface in order to remove the sludge that has accumulated. However, when such a configuration is employed, the underground penetration of rainwater from the bottom surface of the base frame 11 is disabled. On the other hand, by applying a water-permeable means such as a perforation for permeating rainwater to the bottom surface of the base frame 11, the underground permeation effect of rainwater is extremely increased. Therefore, the penetration of rainwater does not hinder the floor,
It is preferable that a means for preventing the passage of sludge, for example, a water-permeable hole provided with a filter means, or a water-permeable frame-shaped opening be formed.

Incidentally, the spacer unit A described above
However, in the embodiment shown in FIG. 2, the connection between the cylindrical portions 2 is made such that the cylindrical portions 2 are firmly connected via the connecting fittings P inserted into the respective top surfaces of the cylindrical portions 2.

By projecting the connection projections into the corners of the corner base 1, the four adjacent blocks can be connected to each other.

Further, when the spacer unit A is stored or transported, the spacer unit A has a truncated cone shape of the upper spacer unit with respect to the truncated cone-shaped cylindrical portion 2 of the lower spacer unit. It is configured such that stacking in a dense state with each other is enabled by fitting the shape cylindrical portions. Therefore, bulkiness during transportation or storage is minimized.

In the embodiment shown in FIG. 2, the four cylindrical portions 2 are formed symmetrically with respect to the center. The number is
The present invention is not limited to the illustrated embodiment. That is,
The cylindrical portion 2 may be one or an appropriate number.

Further, the form of the cylindrical body 2 is not limited to a truncated cone as shown in the figure, but it is preferable that the form can be stacked in a dense state as described above. A cylindrical body having an arbitrary cross-sectional shape such as a polygon or an ellipse may be used as long as it can be stacked.

The planar shape of the base portion 1 may be an arbitrary shape such as an appropriate polygon other than a square shape as shown in FIG. In other words, the planar shape of the base 1 may be any shape that enables continuous combination on the same plane.

According to this, the rainwater flowing from the upper part of the sewer will
Once inflow into the structure according to the invention, it will be stored. Therefore, the water penetrates into the ground, that is, is penetrated into the ground from the inner wall surface of the water tank forming recess.

In the case where a large amount of rainwater flows in and the underground infiltration cannot be made in time, the underground seepage is released to the downstream side of the sewer by the action of overflow. Since the escape water cannot be digested due to the above-described infiltration into the ground, the sewer is prevented from overflowing.

The fine foreign matter contained in the rainwater that has flowed in accumulates in the base frame 11 as sludge. Therefore, after draining the water periodically, a worker is sent into the base frame 11 to remove the sludge artificially.
