Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method for treating spring water in a basement.

(Conventional technology) As a conventional method for treating spring water in a basement, as shown in Fig. 12, an outer wall (b) is constructed of reinforced concrete inside a retaining wall (a), and then a concrete block or the like is formed on the indoor side. The inner wall body (c) is constructed by this, and the spring water that has penetrated through the outer wall (b) is collected by the inner wall body (c), and the pit (f) provided on the slab (e) via the water pipe (d) or the like. The double wall method of collecting and treating water was adopted.

 (G) in the figure is a floor slab.

In addition, without forming a double wall, as shown in FIG. 13, a PC board in which permeable concrete or other porous material (h) and ordinary concrete (i) were integrated was used as a formwork. A method of constructing an underground outer wall (b) by placing concrete between a PC board and a retaining wall (a) and providing a spring treatment layer between the retaining wall (a) and the PC board is known. Was adopted.

(Problems to be Solved by the Invention) However, in the former method, in addition to the trouble of forming a double wall, a wall is constructed in a hollow section defined by existing columns, wall beams, and the like, so that work efficiency is increased. However, there is a problem that extra work is required, such as poor arrangement of the reinforcing bars for the wall.

In the latter method using a PC board in which permeable concrete or other porous material and ordinary concrete are integrated, there is a problem that the PC board is large in weight, which requires construction equipment and labor.

The present invention has been proposed in view of the problems of the prior art described above, and the object thereof is to reduce the labor significantly compared to the conventional method, and to provide a basement in which a reliable spring water treatment effect is exhibited. The point is to provide a spring water treatment method.

(Means for Solving the Problems) In order to achieve the above-mentioned object, according to the spring water treatment method for a basement according to the present invention, a large number of recesses are formed between a large number of recesses formed so as to be directed outward from the inner side surface. In the spring treatment member comprising a water-impermeable plate material having a projection portion, a plate material is arranged between the respective inner projection portions to form a continuous water guide portion vertically and horizontally and a driving form for an underground outer wall is formed. Forming, placing the driving formwork inside the retaining wall, and casting concrete on the outer wall between the retaining wall and the driving formwork so as to be filled in the protrusions. It is.

(Operation) According to the present invention, as described above, the driving formwork for the concrete underground outer wall opposed to the inner side of the retaining wall is provided between the projections of the spring treatment member formed of the water-impermeable material plate. The infiltration water of the underground outer wall concrete is stopped by the impervious spring water treatment material.

Further, permeated water from the joint of the spring treatment member, the penetration of the separator, etc. to the indoor side passes through an intermediate portion formed between the projection of the spring treatment member and the plate in the driving formwork. And the water leaks into the room.

(Example) Hereinafter, the present invention will be described with reference to an illustrated example.

(A) is a driving form for an underground outer wall, which forms a number of recesses (1) directed outward from the inner surface of the water-impermeable plate;
The spring treatment member (3) having a large number of protrusions (2) formed between the respective recesses (1) has a PC plate (4) attached between the inner protrusions (2). .

As the spring treatment member (3), for example, a spring treatment member described in Japanese Patent Application No. 2-59709 proposed by the present applicant may be used.

Then, a water-guiding member is laid on the pressure-resistant slab as a block of the driving formwork (A).

In addition, a floor water guide is connected to the water guide hole of the water guide member.

Next, the driving form (A) is installed on the water guide member so as to face the retaining wall (B), and the driving form (A) is used as an inner form and is connected to the retaining wall (B). An outer wall (C) is constructed by casting concrete in between.

Since the illustrated embodiment is configured as described above,
The permeated water of the underground outer wall (C) concrete is stopped by the impervious spring water treatment member (3).

When the spring water permeates into the room from the joint of the spring treatment member (3) or the penetration portion of the separator, the projection (2) of the spring treatment member (3) and the PC board (4) Is guided to the lower water guiding member (d) by the hollow part formed between the slab and the water is drained to the floor water guiding part (f) provided in the slab, thereby preventing water leakage into the room. (Refer to FIG. 5.) Further, since the protrusions (2) are filled with concrete, the anchors of the indoor side PC board are firmly fixed.

FIG. 3 shows another embodiment of the driving formwork (A), in which a locking hole (5) provided in a projection (2) of a spring treatment member (3) and a PC board (4). Anchor locking projection (6)
Is configured.

FIG. 4 shows still another embodiment of the driving formwork (A), in which a locking projection (7) projecting from a projection (2) of the spring treatment member (3) is connected to a PC board. It is configured to engage with the locking recess (8) of (4).

FIG. 6 shows another embodiment of the present invention, in which a corner-portion water-guiding member (11) having a water-guiding member (10) connected to the water-guiding unit is laid on the pressure-resistant slab (9) (see FIG. 7). And after casting the outer wall concrete (12), the water guide member (11)
And a floor spring member (13) (see FIG. 8) is constructed on the pressure slab (9). (See FIG. 6) (14) in the figure is a floor slab.

FIG. 9 is a partially detailed view of FIG. 1, where p is a separator, q is a waterproof packing, and r is a drainer.

FIGS. 10 and 11 show a reference example not included in the present invention, in which the spring treatment member 3 is attached to the retaining wall 12, the inner form is built, and the outer wall concrete is cast. .

In FIG. 11, s is a hole anchor, and other parts equivalent to those in the above embodiment are denoted by the same reference numerals.

According to this embodiment, the present invention is applied to a case where the amount of spring water is large, and the inner form can be used with either a driving form or a diversion form.

(Effects of the Invention) According to the present invention, as described above, the entirety is made of a water-impermeable plate material, and a large number of inner projections are formed between a large number of recesses formed so as to face outward from the inner side surface. A plate material is disposed between the same inner protrusions in the provided spring water treatment member to form a driving form for an underground outer wall, and the driving form is used as an inner form and between the retaining wall and the pier. Since the underground outer wall was constructed by casting concrete, the permeated water of the underground outer wall concrete is stopped by the impervious spring treatment member.

Further, when the spring water permeates into the room from the joint of the spring treatment member or the penetration portion of the separator, the hollow portion formed between the projection of the spring treatment member and the plate in the driving formwork. It is guided further downward, and leakage into the room is shut off.

Further, according to the present invention, it is not necessary to construct a double wall for stopping water of a spring, which is conventionally provided separately from the outer wall, so that the number of steps can be significantly reduced.

The invention according to claim 2 is characterized in that, after laying a corner water guide member connected to the water guide portion of the wall driving formwork on the pressure-resistant slab, arranging the formwork, casting the outer wall concrete, and forming the corner portion. A floor spring slab is provided on a pressure-resistant slab connected to a water guiding member to construct a floor slab, thereby treating spring water in a corner of a basement.
