The specific embodiment
With reference to the following drawings, embodiments of the present invention are described.
Fig. 1 means that the closed conduit that catchments of the present invention stops up a preferred embodiment of removing device with eyelet, is (a) sectional view radially of header, (b) is sectional block diagram.
In the present embodiment, the header 1 that forms the closed conduit that catchments filter pipe as shown in Figure 2 forms, and this header 1 is embedded in the closed conduit that catchments and buries underground in portion 10.
The closed conduit that catchments is buried portion 10 underground to cover the mode of header 1, be arranged in the scope of the total length that header 1 lays, large sandy gravel stratum 11, middle sandy gravel stratum 12, little sandy gravel stratum 13 and layer of sand 14 are laid in from bottom to top to the mode of cross section inverted pyramid shape, form, this large grit layer 11 has been paved with the gravel in larger footpath, in this, sandy gravel stratum 12 has been paved with than the little gravel of large sandy gravel stratum diameter, this little sandy gravel stratum 11 has been paved with the little gravel of sandy gravel stratum diameter in ratio, and header 1 is embedded in large sandy gravel stratum 11.
The upper surface 14a of layer of sand 14 is riverbeds, and the water in rivers and creeks 15 penetrates the portion of burying underground 10 and becomes river bed water, and from the filter pipe of header 1 by and fetched water.
Form the porous scavenge pipe 2 that eyelet of the present invention stops up the major part of removing device, be positioned at the upside of header 1, in the mode extending abreast with header 1 in burying the large sandy gravel stratum 11 of portion 10 and the interface of middle sandy gravel stratum 12 underground, arrange.Fig. 2 represents the part of header 1 and porous scavenge pipe 2, is (a) lateral view, is (b) top view.And Fig. 3 amplifies the part that represents porous scavenge pipe, (a) is lateral view, is (b) radial cross-section.
Header 1 is only bonded together known filter pipe and form with desired quantity, as an example, can use the known filter pipe that diameter is 60cm～1m.Although used in the present embodiment filter pipe, as header, be not limited to this, also can use other the pipe such as porous steel pipe, porous plastics pipe and steel concrete antipriming pipe processed.
In the present embodiment, as shown in Figure 2, with respect to a filter pipe 1, make the porous scavenge pipe 2 of three one group in the sandy gravel stratum of the upside of header 1 with level setting, each scavenge pipe 2 is at its open two ends, be connected on the chamber 3 of two tubuloses that configure in the mode vertical with scavenge pipe 2, and be communicated with these two chambers 3.One in two chambers 3 is connected on the air compressor 4 that forms compressed air feed mechanism of the present invention via not shown pipe arrangement.The other end that one end is connected to the chamber 3 on air compressor is closed, and the both ends of other chamber 3 are closed.For scavenge pipe 2, as an example, can use the pipe that diameter is 25mm～40mm.
In addition, for chamber 3, as an example, can use diameter for the pipe of 100mm left and right.In the present embodiment, as shown in Figure 3, the air squit hole 5 of scavenge pipe 2 is formed on two positions, left and right in the bottom of scavenge pipe 2, and the diameter of air squit hole 5 can be for example 2mm.
