Background technology
Regulating reservoir or the winding shaft of the form guide that the percolate of landfill yard adopts gravity current conventionally outside reservoir area, the installation of gravity discharge guiding pipe adopts mode as shown in Figure 1 mostly, comprise a straight mozzle 5 that is directly communicated with reservoir area 1 and regulating reservoir 2 through dam body 3, cover the antiseepage film 4 on reservoir area 1 and regulating reservoir 2, dam body 3, and be enclosed within mozzle 5 two ends, be sealedly connected on the pipe box 6 between mozzle 5 sidewalls and antiseepage film 4.
When mozzle 5 is domatic through the dam body that is equipped with antiseepage film 4, cut open the antiseepage film 4 at poling position, again the sealing at this position adopts general " pipe box " covering process in antiseepage treatment process, use HDPE film (density polyethylene film with high) to be made into a pipe box 6 that is bell mouth shape, the domatic antiseepage film 4 of one end of pipe box 6 and dam body is welded, and the other end is also reinforced (as shown in Figure 2) together with mozzle 5 welding.The pipe that this " pipe box " antiseepage treatment process is used in landfill reservoir area widely is at present worn membranous part position.
In practical engineering application, find, pipe box 6 is easily torn with the annular junction of antiseepage film 4, thereby leakage of leachate occurs, and causes groundwater pollution.Cause that pipe box 6 and antiseepage film 4 junctions tear because have: one, the domatic antiseepage film 4 of dam body is vulnerable to the power from vertical direction.The removable amount of the pipe box in the vertical direction of two, laterally installing is little.Three, pipe box 6 junction stress are concentrated.The acting in conjunction of above three factors, has caused pipe box 6 and the junction of domatic antiseepage film 4 to be easily torn.
The advocating of vertical direction will be produced by following two reasons:
One, the differential settlement of dam body: reservoir area dam body 3 occurs that mozzles 5 obviously sink but dam body 3 sinks when not obvious, and mozzle 5 can sink with pipe box 6, the junction of pipe box 6 and domatic antiseepage film 4 has been subject to support and has drawn.Can side-play amount little due on pipe box 6 vertical directions, cause stress to concentrate on junction and the generation (as shown in Figure 3) that causes this position to be torn.
Two, the rising of underground water: if more than groundwater level rises to pipe box 6 absolute altitudes when flood season, thereby the huge buoyancy meeting pushing tow antiseepage film 4 stay bolt pipe boxes 6 that underground water brings to antiseepage film 4, and finally cause pipe box 6 and the annular junction of antiseepage film 4 to occur tearing (as shown in Figure 4).
Once there is antiseepage film 4, being torn, will there is breakthrough and polluted underground water in whole seepage control system, occur production accident and even the rectification that stops production.
Summary of the invention
