On the other hand, as shown in FIG. 8 , the water tank 100 of the present invention lengthens the path (residence time) of water that is obtained through the water inlet unit 101 and then discharged through the water outlet 102 in the internal storage space. In order to include a guide wall (30). The acquisition unit 101 and the water outlet unit 102 are respectively formed on opposite sides (eg, a diagonal corner in the case of a rectangular water tank 100).

As shown in FIG. 8 , two or more guiding walls 30 are installed in a zigzag form in the water tank 100 when viewed in a plan view, so that the water obtained through the acquisition unit 101 flows through the zigzag flow path on the opposite side. In other words, one side is fixed to the inner wall of the water tank 100 while the other side is spaced apart from the inner wall of the water tank 100 so that water passes through.

The configuration of the guiding wall 30 is based on the water flow guide panel 31, and if necessary, the pillar 32 is included, preferably at least two water flow guide panels 31 and at least one pillar 32 (preferably). concrete) is alternately and repeatedly installed. In the case of a small water tank, it is possible to install the water flow guide panel 31 without using a pillar, but in the case of a large water tank, it is difficult to use only one water flow guide panel 31, so that the pillar 32 is included, and the water flow The fixing of the guide panel 31 and the pillar 32 is possible in various ways, such as a method of fixing the water flow guide panel 31 to the pillar 32 by anchoring.

The water flow induction panel 31 is made of stainless steel and includes a reinforcing part to increase flexural rigidity, and the reinforcing part is formed in one or more of the vertical and horizontal directions through bending, or in the form of a protrusion (rib). .

As such, one side of the water flow inducing panel 31 is connected to the inner wall of the water tank 100, and water may stagnate and become contaminated in this portion. To solve this, the water flow inducing panel 31 and the water tank 100 A shooter guide panel 40 for preventing shooter is applied to the part where the inner wall is connected.

As shown in FIGS. 8 and 9 , the shooter guide panel 40 is connected to the end of the water flow guide panel 31 and is supported on the inner wall of the water tank 100 by itself to naturally direct water flowing from the inlet side to the outlet side. It is preferably divided into an induction-side induction part 41 and an outflow-side induction part 42 to induce.

The induction side induction part 41 and the water outlet induction part 42 induce the flow of water using a slope, respectively, that is, the induction side guide part 41 guides the water flowing from the acquisition side to the water flow induction panel 31. It is inclined toward the water flow induction panel 31 for this purpose, and the water outlet side guide part 42 is inclined toward the inner wall to guide the water flowing along the water flow guide panel 31 to the inner wall of the water tank 100 .

According to the structure of the acquisition-side guide part 41 and the water-outlet-side guide part 42, an approximately triangular space 43 is formed on the inner wall of the acquisition-side guide part 41 and the water outlet-side guide part 42 and the water tank 100, In order to prevent water from accumulating in this space, the water induction section 41 and the water outlet guide section 42 are configured so that some water passes through the space 43 without flowing along the water flow guide panel 31 .

Its configuration is all possible configurations in which water passes through the water induction section 41 and passes through the space 43 and then passes through the water outlet guide section 42, for example, which is formed in the induction section 41 One or more shooter guide holes 44 , the water outlet side guide portion 42 and the open portion 45 formed between the inner wall of the water tank 100 .

The acquisition-side guide part 41 is formed as one or more shooter guide holes 44 (circular, etc.) as a plate so that some water passes through the shooter guide holes 44 to flow into the space 43 .

The water outlet-side guide part 42 has the open part 45 to form a larger water passage area than the shooter guide hole 44 to quickly guide the water flowing into the space 43 toward the water outlet 102 , and at this time, open Water passing through the part 45 can accelerate the flow rate of water flowing along the water flow induction panel 30, thereby helping to prevent water stagnation in this part.

As shown in Figure 10, the induction side induction part 41 and the outflow side induction part 42 can be applied by being fixed (welding, etc.) on both sides of the water flow induction panel 31, respectively, after being manufactured as a single piece.

The shooter guide panel 40 is also possible with a triangular cross-section block with no space inside, and in this structure, it induces the flow of water through the inclination of the inlet side and the water outlet side.

11 to 13 are other exemplary views of the water flow guide panel 31, the water flow guide panel 31 is the inlet side water flow guide 33 and the water outlet side water flow guide 34, and a through hole 35 formed therebetween. ) is included. These components are formed in one or more places (shown as one place in the figure) between both ends of the water flow inducing panel 31 along the flow direction of the water in the water flow inducing panel 31 .

The inflow-side water flow guide 33 and the outflow-side water flow guide 34 allow water to flow smoothly without stagnation on the wall side of the water flow induction panel 31, and the upstream side of the water flow induction panel 31 (intake side) and the downstream side (outlet side), and specifically, one side is connected (fixed) to the water flow guide panel 31, while going to the other side, it is formed to be inclined away from the water flow guide panel 31 along the direction of the water flow. It gives the flow of water through the slope.

The through hole 35 prevents the shooter from being formed on the inside of the inlet-side water flow guide 33 and the outflow-side water flow guide 34, and is formed so that the upstream side and the downstream side pass through the water flow guide panel 31, so that the water let this pass

As illustrated in the drawing, when the inlet-side water flow guide 33 and the outflow-side water flow guide 34 are symmetrically formed in the water flow induction panel 31, the through-hole 35 is formed in the ingestion-side water flow guide 33 and the outflow-side water flow. By being formed between the guide 34, both the acquisition side and the water outlet side can prevent shooting, so the structure can be simplified, and the water on the water outlet side is pushed with the water on the acquisition side, and the anti-shooting effect is very excellent.

In addition, since the water flow guide panel 31 is thinner than the pillar 32, a corner is formed in the portion where the water flow guide panel 31 and the pillar 32 are connected, and this corner is a part where a shooter can occur. An inclined guide 36 is included so that water can flow naturally.

The construction method of the concrete structure stainless steel lining water tank having a water-proof function according to the present invention consists of the construction of the civil foundation part - the concrete part construction of the water tank - the stainless steel lining construction process of the water tank.

The civil foundation construction process is to construct a reinforced concrete chain preferably as a foundation for supporting the water tank, and after reinforcing the reinforcement and installing the formwork, the concrete is poured and cured in the pouring space to construct it. The base portion is composed of only the bottom portion or the wall portion is formed together with the periphery of the bottom portion.

In the concrete part construction process of the water tank, the concrete part 10 is constructed by reinforcing reinforcing bars inside the base part and installing the formwork, then pouring and curing the concrete, and at this time, the formwork is supported through the concrete fixing tie. However, the concrete fixing tie is used for the construction of the stainless steel lining part.

In the stainless steel lining construction process of the water tank, when the formwork is demolded in the previous process, it can be confirmed that a part of the concrete fixing tie protrudes to the outside of the concrete part 10, and the fixing band 21 on the protruding part of the concrete fixing tie and lining the surface of the concrete part 10 by fixing the lining panel 22 to the fixing band 21 .
