Wherein, overcoat chimney filter 201 and collector pipe 202 use stainless steel manufacture, to adapt to be embedded in underground soil for a long time
Body environment, it is to avoid corrosion, both are evenly equipped with some filter openings on wall, the diameter of filter opening should be less than the grain of filtrate in filter material layer 203
Footpath, overcoat chimney filter 201 caliber is more than collector pipe 201 and is set in the periphery of collector pipe 201；Overcoat chimney filter 201 and collector pipe 202
Between be interconnected and fixed to be integrally formed structure, it is simple to transport, it is possible to simplify installation steps.
As Figure 1-3, the MULTILAYER COMPOSITE chimney filter structure in the present embodiment is applied to below building sole plate with
The method carrying out anti-floating is:
(1) on the sole plate 10 of existing building, offer spilled water hole to reduce pressure, then open on sole plate 10
If basis well slot 101, drilling equipment is used to utilize sleeve pipe retaining wall to carry out into well operations, by aforesaid MULTILAYER COMPOSITE in soil layer 11
Chimney filter structure 20 sinks at the bottom of hole, after pulling out sleeve pipe, sets a seal ring 102 in the bottom of sole plate 10 around collector pipe 202, and
At the top of sole plate 10, one circle waterstop 104 is set around cell wall, in the well slot 101 of basis, uses microdilatancy antiseepage afterwards
Concrete 103 recovers sole plate 10；
(2) it is sequentially arranged above inlet pipeline 30, hydraulic pressure control pipeline 40, outlet pipeline 50 at sole plate 10 after
