Supplementary explanation: the newly-built earth dam that the present invention designs refers to Clay Microstructure dam, in the anti-seepage reinforcing work of newly-built earth dam
The impervious body structure drained under antiseepage, film on its 12 film of geomembrane in journey is to be laid in Clay Microstructure back in dam.Previous soil
Dam seepage control project causes to prevent since the vertical, horizontal drainage system of complete set being arranged under the geomembrane 12 not in impervious body
After seeping completion of works, there are still the saturations that height is different in earth dam, that is, the water in reservoir still penetrates into dam body, thus
Seepage failure is generated, earth dam safety is threatened.It is this in earth dam geomembrane anti-seepage reinforcing engineering under antiskid slot and film vertically and horizontally
Rhone 4, which is arranged together between making each rhone 4, to be respectively formed antiseepage independent draining subsystem this is allowed between two slots
Once leakage caused by there is film holes will not influence the anti-seepage effect of entire earth dam, and also can be timely in engineering management
It was found that, in time processing.
Design of the invention can be achieved: connecting in defective or use process when geomembrane 12 is constructed has breakage to cause library
When water is penetrated under the film of geomembrane 12, the drainage system that can be vertically and horizontally arranged rapidly is pooled to collecting-tank 2 and by dam bottom
Drainpipe 3 is expelled to one side of downstream slope on dam, it can be ensured that the saturation of earth dam is low flat or even completely eliminates saturation, earth dam infiltration
Percolation line pipe and corollary apparatus can be arranged by multiple appropriate places in dam body to realize in the monitoring of line.The present invention passes through
The combination of " stifled " and " thin ", it is ensured that the safety of earth dam.
Technology mechanism of the invention is both the guiding principle of the dangerous earth dam of radical cure disease, and prevents newly-built earth dam and generate the dangerous library of new disease
Guiding principle.The drainpipe 3 that Φ 100 can be used for the specification of dam bottom drainpipe 3, the setting of dam bottom drainpipe 3 can when eradicating disease danger earth dam
It is constructed with ZT-32 type non-excavation pipe-laying drilling rig, it is pre-buried that bank then can be used in the setting of the dam bottom drainpipe 3 of newly-built earth dam.
