When carrying out common water intaking after water intake well 1 is set, drive the suction pump (not shown) being arranged in gangway ladder 4 grade of water intake well 1, the water flowed in water intake well 1 from outside by intake 2 is drawn up and is taken out to outside.
The slit between the wedge wire 13 of filter 6 due to lasting long-term water intaking produces the blocking caused by gravel, rubbish, sand etc., make back washing fluid flow into back washing pipe 7 from back washing fluid container 19 via back washing fluid supply line 12, and make back washing fluid spray to filter 6 from the back washing fluid ejiction opening 7a of each back washing pipe 7. Thus, the blocking caused by gravel and rubbish etc. between the wedge wire 13 of filter 6 is removed. Now, the water in water intake well 1 temporarily becomes muddy, so interrupt common water intaking during this period, but works as the back washing end of job and stops ejection back washing fluid, then the outflow of muddy water also terminates, and just can recover common water intaking.
Then, illustrate with reference to Figure 10 other embodiments that the intake of the water intake well of the present invention is constructed. In Fig. 10, the element identical with Fig. 4 is illustrated with identical labelling, and omits detailed description.
In the present embodiment, different from the embodiment of Fig. 4 in following, i.e. present embodiment is not provided with back washing pipe 7 as the embodiment of Fig. 4, but makes filter protection pipe 5 have the function as back washing pipe.
That is, multiple filters protection pipe 5 forms multiple back washing fluid ejiction openings of oriented filter 6 opening respectively in the vertical direction at a prescribed interval. Preferably configure between each back washing fluid ejiction opening and adjacent protection pipe 5 protecting pipe 5 staggeredly. Back washing fluid supply line 12 is arranged in inside the water intake well radial direction of filter protection pipe 5 on the top of intake 2, and is connected on back washing fluid container 19 via pipe arrangement 18. As shown in figure 11, back washing fluid supply line 12 protects pipe 5 to be connected by the connecting tube 15 identical with the connecting tube 15 shown in Fig. 4 with each filter.
