Abstract
The invention relates to a simple and practical water-seal technology when various pipelines penetrate a waterproof geomembrane. A tube support is arranged on a position where a pipeline penetrates a membrane; a rigid waterproofing sleeve which receives a membrane penetrating pipeline inside is arranged in the tube support, and the geomembrane is embedded in the tube support, wherein, the tube support can be of a concrete structure, and cover the tail end of the geomembrane inside during a casting process to achieve the aim of anti-seepage. The water-seal structure for the pipeline penetrating the membrane provided by the invention can be widely applied to a soil pool side slope, a flood dike side slop, a retaining wall and so on, and can greatly improve and increase the anti-seepage performance when the geomembrane is penetrated by the pipeline.
Description
Technical field
A kind of simple and practical water-stop technology when the present invention relates to various pipes and passing waterproofing geomembrane.
Background technique
As the antiseepage base material, with the non-woven fabric compounded geotechnological impervious material that forms, its barrier performance depends primarily on the barrier performance of plastic pellicle to geomembrane with plastic pellicle.At present, the plastic pellicle that antiseepage is both at home and abroad used mainly contains PVC (PVC) and polyethylene (PE), and they are a kind of polymer chemistry flexible materials, and proportion is less, and extensibility is stronger, adapts to the deformability height.Corrosion-resistant, low temperature resistant, good frost resistance.Its dominant mechanism is to cut off the earth dam leak paths with the impermeability of plastic pellicle, bears hydraulic pressure and adapts to dam deformation with its bigger tensile strength and specific elongation; And nonwovens also is a kind of polymeric staple fiber dimension chemical material; by acupuncture or hot sticky shaping; have advantages of higher tensile strength and extensibility; it is with after plastic pellicle combines; the tensile strength and the anti-puncture ability of plastic pellicle have not only been increased; and, increased the friction factor of surface of contact because nonwoven surface is coarse, help the stable of composite geo-membrane and protective layer.Simultaneously, they have erosion resisting preferably to bacterium and chemical action, the erosion of have good effect in acid, alkali, salt.
But present geomembrane is when running into pipeline and pass, and geomembrane is met pipe and need be blocked, and seepage control system goes to pot, thereby influences whole anti-seepage effect.
Summary of the invention
In order to solve geomembrane when running into pipeline and pass, the problem of its antiseepage ability drop the invention provides a kind of brand-new water stop structure for pipeline penetrating film.
Technological scheme of the present invention is: the position of pipeline penetrating film is provided with a base, is provided with an appearance in the base and wears the rigid waterproofing sleeve pipe that the film pipeline is placed in one, and geomembrane embeds in the base.
Wherein, base can be a concrete structure, and in casting process the geomembrane end is wrapped into wherein, reaches the purpose of antiseepage.
The geomembrane end places the length of base preferably to be not less than 800mm.Preferably be not less than 200mm and reserve concrete thickness between geomembrane and rigid waterproofing sleeve outer wall.
Water stop structure for pipeline penetrating film provided by the invention can be widely used in Tu Chibianpo, flood bank side slope, shore protection etc., can improve geomembrane greatly and meet the barrier performance of pipeline when passing.
Description of drawings
Fig. 1 is the sectional view of the structure of the embodiment of the invention;
Fig. 2 is the front view of the structure of the embodiment of the invention.
Embodiment
As illustrated in fig. 1 and 2, comprise a base 3 in the water stop structure for pipeline penetrating film provided by the invention, be provided with an appearance in the base 3 and wear the rigid waterproofing sleeve pipe 4 that film pipeline 2 is placed in one that geomembrane 1 embeds in the base 3.There is geomembrane protective layer 5 both sides of the geomembrane outside the base 3.In the present embodiment, geomembrane insertion concrete length L is 900mm; Reserving concrete thickness t between geomembrane 1 and rigid waterproofing sleeve pipe 4 outer walls is 250mm.
Claims (3)
1, water stop structure for pipeline penetrating film comprises and wears film pipeline and geomembrane, it is characterized in that being provided with a base, is provided with an appearance in the base and wears the rigid waterproofing sleeve pipe that the film pipeline is placed in one, and geomembrane embeds in the base.
2, water stop structure for pipeline penetrating film according to claim 1 is characterized in that the geomembrane end places the length of base to be not less than 800mm.
