Abstract

PURPOSE:To make it possible to treat spring water with the cutting depth of the ground reduced by laying spring water treating units formed by spring water treating blocks having notches whose side face extends in one direction on a floor plate, and forming a spring water treating layer between the spring water treating units and a floor slab. CONSTITUTION:Plural spring water treating units 11 formed by spring water treating blocks 15 having notches 15a extending in one direction on the side faces are laid a specified space apart on the floor plate 10 of a foundation or a structure. A spring water layer is formed between the spring water treating units 11 and a floor slab 13. First drainage channels 16 formed by notches 15a and second drainage channels 17 which intersect the first drainage channels 16 and are formed between the spring water treating channels 11, are lengthwise and crosswise formed to recover spring water such as underground water, generated in the foundation or the structure. Spring water treatment with the cutting depth of the ground reduced can thus be performed, and thereby construction cost can also be reduced.

Description

[Detailed description of the invention] "Industrial application field" The present invention relates to a spring water treatment structure using blocks.

``Conventional technology'' Conventionally, when constructing foundations or building structures, etc., it has been known to eliminate underground beams and use a flat slab of concrete as the bottom base in order to reduce the depth of underground excavation. There is.

To implement this construction method, a running water space is required to drain and treat groundwater that enters into the foundation or building structure, and the conventional construction method shown in Figures 9 to 11 is Known (Unexamined Japanese Patent Publication 1986-
40436).

In this construction method, a plurality of blocks 4 each having legs 3 protruding from one surface of a flat plate 2 are laid on a lower slab l at the bottom of an underground structure A, and the upper surface of the blocks 4 and the surface of the lower slab l are connected. A spring water tank B is formed which is inserted vertically and horizontally in between, and block 4 is also formed.
The upper slab 5 is constructed by pouring concrete on the upper surface of the tank B, and the spring water is stored in the spring water tank B for wastewater treatment.

``Problems to be Solved by the Invention'' However, in the above construction method, when forming the spring water tank B, the block 4 is shaped into an uneven shape with a chevron-shaped leg 3 protruding from the flat plate 2. The manufacturing cost per piece is higher than that of general flat blocks, etc.
This construction method, in which a large number of them are used, has a problem in that the construction cost increases. In addition, due to the shape of the block 4, the rigidity of the block itself, that is, the strength against overloading load, is lower than that of a flat block. Therefore, due to long-term use or earthquakes, etc., the durability will decrease and the structure above it will be damaged. There was a fear that it would tilt.

This invention has been made in view of the above circumstances, and has a spring water treatment structure using blocks that is capable of effectively draining spring water generated on foundations or structures, etc., while reducing construction costs, and has excellent durability. is intended to provide.

"Means for Solving the Problems" The present invention provides a method for installing a plurality of spring water treatment blocks and/or spring water treatment units including the spring water treatment blocks at predetermined intervals on the floor of a foundation or structure. By doing so, a spring water treatment layer is formed between it and the concrete floor slab above it, and the spring water treatment block is composed of a flat block having a notch extending in one direction on the side surface, and the spring water The treatment layer includes a first drainage channel that extends in one direction and is defined by the notch of the spring water treatment block, and a first drainage channel that intersects with the first drainage channel and connects the spring water treatment block and/or the spring water treatment unit. The structure includes a second drainage channel formed in between.

Note that it is desirable to bury a PC steel wire in the floor board.

``Function'' By using the spring water treatment blocks and/or spring water treatment units described above and laying multiple blocks on the foundation or the ground of a structure, spring water from groundwater etc. can be removed from the floor of the structure. The water is discharged to the sewer system through drainage channels formed vertically and horizontally in the spring water treatment layer between the board and the concrete floor slab. This makes it possible to reduce the depth of ground excavation when constructing a foundation or building structure, and eliminates the need for formwork for constructing underground beams.

"Embodiments" Hereinafter, embodiments of the present invention will be described with reference to the drawings.

1 to 5 show examples in which a spring water treatment structure using blocks according to the present invention is installed in a floor structure of an underground structure or the like.

As shown in Figure 1, on the bottom surface formed by excavating the ground G,
A pressure-resistant floor plate 10 formed by arranging reinforcing bars and pouring concrete is provided, and an unbonded PC steel wire 10a is buried in the concrete so as to be located on the tension side of the floor plate 10.

A plurality of spring water treatment units 1 are installed on such a floor plate 10.
1 are laid at a predetermined distance from each other, and formwork 1 is placed on top of it.
2, concrete is cast to form a floor slab 13, and a spring water treatment layer 1 is formed between the floor slab l3 and the floor plate lO.
4 is formed.

The spring water treatment unit 1-11 is composed of a plurality of flat spring water treatment blocks 15 having notches 15a extending in one direction (eight directions) on both sides, and adjacent spring water treatment blocks 15 A first drainage channel l6 extending in one direction (eight directions) is formed between the notches 15a. In this embodiment, the spring water treatment unit l1 has six spring water treatment blocks l5 in one direction and three spring water treatment blocks l5 in the other direction (direction B).
The first drainage channels 1 are arranged in a row and have two in one direction.
6 are formed in parallel.

Such spring water treatment units 1l are arranged on the floorboard 10 at appropriate intervals from each other, and extend in the other direction (direction B) between adjacent spring water treatment units 1l, and are arranged on both sides. A second drainage channel 17 is formed which communicates with the first drainage channel l6.

Therefore, in the spring water treatment layer 14, drainage spaces consisting of the first and second drainage channels l6 and l7 are provided vertically and horizontally.

Note that the outlets of the first and second drainage channels l6 and l7 are, for example, a reservoir tank (not shown) constructed in the ground G that stores spring water W such as groundwater, and drains from there to a sewer or the like. Just do it like this. In addition, when the amount of spring water W is large, the first drainage channel l6 is formed by opening a predetermined interval Q without aligning the sides of the collapse water treatment block l5, as shown in FIG. 4. When the cross-sectional area of block 16 is thicker than 16, and concrete is poured thereon, formwork 18 may be placed on the upper surface of spring water treatment block 15. Furthermore, the formworks 12 and 18 may be made of plywood, iron, plastic, or the like, and if the width is narrow, taping or other means may be used.

As shown in FIG. 5, the spring water treatment block l5 constituting the spring water treatment unit 11 has a flat plate shape as a whole, and in this embodiment, each dimension of length, width, and height is Each test is set to about 390 questions, 200mm, and 80em. The upper surface 15b and lower surface 15c of this spring water treatment block 15 are flat, and the notch 1 curved inwardly at both lengthwise edges (i.e., direction A) of the lower surface 15c.
5a is formed. Further, a plurality of through holes 19 having a relatively large inner diameter are bored in the width direction of the spring water treatment block 15 for the purpose of reducing weight and the like. Furthermore, in order to effectively treat the spring water, the upper surface 15b of the spring water treatment block 15 may be coated with a waterproof coating to prevent the spring water from rising. The spring water treatment block 15 is mainly made of concrete, and may also be made of sintered bricks or the like.

According to the spring water treatment structure of this embodiment, the following effects are achieved.

■ Spring water W such as groundwater can be efficiently collected in the first and second drainage channels 16 and 17 formed vertically and horizontally in the spring water treatment layer 14, and all the spring water W can be drained to the sewer etc. By providing a spring water treatment structure at the bottom of a foundation or building structure, it is possible to effectively prevent groundwater from flooding.

■ The spring water treatment layer l4 is constructed by laying a plurality of flat spring water treatment blocks 15 having cutouts 15a on the sides, so construction is easy and the spring water treatment blocks 15
Since it is possible to mass-produce products of the same standard, construction costs can be greatly reduced. Further, by widening the distance between the spring water treatment blocks 15 and increasing the cross-sectional area of the drainage channel, it is possible to cope with geological formations with a large amount of spring water.

■ The spring water treatment block 15 has a notch 1 only on the side edge.
It has a relatively smooth shape that forms the floor plate 1
0, the stability is good when the spring water treatment block 15 is laid on top of the ground, and since the spring water treatment block 15 itself has high strength and rigidity and is excellent in durability, there is a risk that some parts may be damaged by external forces such as earthquakes. Less is.

In the above embodiment, one of the arrangement patterns for forming drainage channels in the spring water treatment layer l4 was shown, but there are other arrangement patterns as shown in FIGS. 6 and 7, respectively.

That is, the spring water treatment structure shown in FIG. 6 is one in which three spring water treatment blocks 15 are arranged as a spring water treatment unit 11, and each adjacent spring water treatment unit 1l has a first drainage channel l.
The orientation of 6 has been changed.

In the spring water treatment structure shown in FIG. 7, two spring water treatment blocks 15 are arranged as a spring water treatment unit 11, and as in FIG. 6, each adjacent spring water treatment unit 11 has a first drainage channel. The direction of l6 has been changed. Also, instead of configuring it into a unit, each spring water treatment block 15 has a drainage channel l6.
, l7 may be provided vertically and horizontally. In any case,
The drainage channel formation pattern in the spring water treatment structure may be appropriately set according to the amount of spring water W, the bottom area of the structure, the ground condition, etc.

FIGS. 8A to 8C show different shapes of the spring water treatment block 15, respectively. The spring water treatment block l5 shown in FIG. 8(a) has a notch l5a with a semicircular cross section formed in the center of the side surface, and the spring water treatment block l5 shown in FIG.
A notch 15a having an L-shaped cross section is formed at the lower end of the side surface, and a spring water treatment block 15 shown in FIG. 8(C) has a tapered notch 15a formed at the lower end of the side surface. When applied to the example, similar effects can be achieved.

"Effects of the Invention" As explained in detail above, the present invention provides a spring water treatment block and/or a spring water treatment unit consisting of the spring water treatment bronc at predetermined intervals on the floor of a foundation or structure. A spring water treatment layer is formed between the spring water treatment layer and the concrete floor slab on top of the concrete floor slab, and the shoulder water treatment block is constructed from a flat block having a notch extending in one direction on the side surface. The spring water treatment layer includes a first drainage channel extending in one direction and constituted by a notch of the spring water treatment block, and a spring water treatment block and/or a spring water treatment layer that intersects with the first drainage channel. Since the structure is equipped with a second drainage channel formed between the water treatment units, spring water such as groundwater can be efficiently drained and treated through the drainage channels formed vertically and horizontally in the spring water treatment layer. The arrangement pattern of the water treatment block and spring water treatment unit can be set as appropriate depending on the amount of spring water and usage conditions, so the range of application is wide. Furthermore, since the spring water treatment unit only requires installing spring water treatment blocks of the same shape, construction costs can be reduced.

In addition, the spring water treatment block has a flat plate shape with few irregularities, and has excellent strength and durability, so there is little risk of damage due to external forces such as earthquakes, and it is stable when installed on the floor. It is high and does not cause problems such as tilting of the structure above it.

Furthermore, there is also the advantage that the manufacturing cost of the spring water treatment block is low.

In addition, by using such a block structure for the spring water treatment structure, it is possible to reduce the depth of ground excavation when constructing foundations or building structures, and it is possible to use a mold for constructing underground beams. This has the advantage of eliminating the need for a frame.
