On water permeability porous outer tube 102,101,1, be equipped with a plurality of slits 1 ' parallel with center line c.Be formed with internal thread 1 in water permeability porous outer tube 102,101,1 downstream separately ".
Fig. 2 is the amplification view of the B portion details of presentation graphs 1.
One distolateral (1c) of the water permeability porous outer tube 1 in downstream is chimeric with the downstream outer peripheral face 2b that is connected interior pipe 2 with its upstream side inner peripheral surface 1b.Therefore, water permeability porous outer tube 1 is that chimeric state is installed on the pipe 2 to be inlaid in the connection.
On the other hand, in the impermeability atresia pipe 4 with is connected in the supporting step 2a butt of pipe 2, with upstream side outer peripheral face 4c with to be connected interior 2 the downstream inner peripheral surface 2c of managing chimeric.Therefore, pipe 4 is that chimeric state is installed on the pipe 2 to be inlaid in the connection also in the atresia.
Again, in water permeability porous outer tube 1 and the impermeability atresia pipe 4 since manage in being connected 2 downstream wall thickness and to have the state configuration of the clearance t of catchmenting.
The prominent bar 5,5 of 2 ring-types is equipped with in the stage casing of pipe 2 in connecting.The water permeability porous outer tube 1 in the external diameter of the prominent bar 5,5 of ring-type and the water permeability porous outer tube 101 of upstream side and downstream external diameter separately equates.Again, be embedded with the water-expansible rubber 3 that absorbs moisture and expand at prominent 5,5 of bars, this water-expansible rubber 3 is carefully encircled 3 ' and is fixed on the interior pipe 2 of connection.
So, attaching the interior pipe 2 of the connection that water-expansible rubber 3 is arranged, water permeability porous outer tube 1 and the interior pipe 4 of impermeability atresia just becomes a state that overlaps, and promptly becomes the state of one.
Equally, the upstream side, the subsidiary interior pipe 20 of connection, water permeability porous outer tube 101 and the interior pipe of impermeability atresia 40 states that also become one (with reference to Fig. 1) that water-expansible rubber 30 is arranged that connect interior pipe 2.Promptly, one distolateral (101c) of the water permeability porous outer tube 101 in downstream is chimeric with the downstream outer peripheral face 20b that is connected interior pipe 20 with its upstream side inner peripheral surface 101b.
Get back to Fig. 2, the upstream side stage casing of pipe 2 is formed with external screw thread 2 in connecting " (round thread).
At this moment, the peristome 40d in the downstream of the interior pipe 40 of impermeability atresia disposes with upstream side inlet 2 ' the devices spaced apart T that is connected interior pipe 2 in its downstream.By this interval T, catchment clearance t and interior pipe 2 connections of being connected of downstream in the water permeability porous outer tube 101 of upstream side and the impermeability atresia between the pipe 40.
As mentioned above, the water permeability porous outer tube 102,101,1 that a plurality of external diameters are identical interconnects, and constitutes multilayer pipe.
According to Fig. 1 the construction of adopting this multilayer pipe is described.
At first, up carry out hole enlargement boring from ground section (Japanese: the cut face) inclination of reinforcements such as concrete towards firm ground.
After afterwards drilling rod and hole enlargement sleeve being extracted from hole enlargement boring, external diameter is slightly smaller than water permeability porous outer tube 102 this boring aperture, that have top cone 15 inserts.
In will connecting in pipe 20, water permeability porous outer tube 101 and the atresia pipe 40 form external members, screw on the downstream inner peripheral surface of the water permeability porous outer tube 102 that is having the top cone at the outer peripheral face of the connection pipe 20 that will be positioned at this external member upstream side.
So, in the hole enlargement boring 10 that wet and slippery soil block 9 angle that is tilted to is arranged wears towards ground in ground surface and collecting well, embed water permeability porous outer tube 102,101,1 successively.
In addition, when the hole wall of the hole enlargement boring 10 that a plurality of water permeability porous outer tubes 102,101,1 edge has just worn inserted, this hole wall was just directly by 102,101,1 supporting of water permeability porous outer tube.
So, the periphery of described a plurality of water permeability porous outer tubes 102,101,1 is connected along described center line c.
Multilayer pipe of the present invention constitutes as mentioned above like that, thereby if after carrying out hole enlargement boring, insert water permeability porous outer tube 102,101,1, just can pass through water-expansible rubber 30 formed underground mill weirs, underground water in the pipe 40, is improved phreatic catchmenting property in the impermeability atresia in the water permeability porous outer tube 102 importing downstreams of upstream side.Equally, by water-expansible rubber 3 formed underground mill weirs, underground water in the pipe 4, can be improved phreatic catchmenting property in the impermeability atresia in the water permeability porous outer tube 101 importing downstreams of upstream side.
Fig. 3 (a) and (b), (c) are the ideographs of expression water-expansible rubber 3 phreatic situation of interception in the hole wall of hole enlargement boring 10.In addition, the gathering surface in the symbol 14 expression porous outer tubes 1, the gathering surface outside 14 ' the expression porous outer tube 1.
Expose water-expansible rubber 3 suctions in pipe 2 stage casings in connecting and expand, on the hole wall that is pressed in hole enlargement boring 10, with underground water interception and shunting,, and then, underground water is directed to the space of interval T by catchmenting clearance t by slit 1 ' in this position.
The wet and slippery intrazonal underground water in ground enters from interval T and connects interior pipe 2 then, and via managing 4 in the impermeability atresia, 8 the outside and collecting well are rejected to the outside on the face of land by drain hole from the face of land.
In addition, in Fig. 1, be formed with beveled face 12 in the end of the water permeability porous outer tube 1 that is projected into the ground off-balancesheet.Be provided with at the upper end of opening surface 12 expansion bearing, the flap valve 13 of 11 ' side opening in the bottom again.
