Abstract
The invention discloses an impermeable rust-proof flange design for a water supply and drainage pipe when passing through a geomembrane, and belongs to the technical field of water supply and drainage of fixed construction in the E department of international patent classification (IPC). The flange design is characterized in that a protective cap is covered on each bolt head and each nut for fixing a flange, and then the bolts are isolated from the water body through sweat soldering. The material of the protective caps comes from the pipe material, namely, a small section of tubing with a diameter slightly larger than that of the bolt head is cut off, and a cap made of the same material is welded on one side. The water supply and drainage pipe, the flange and the protective caps are made of the same material which is polyvinyl chloride (PVC) or polyethylene (PE), and the bolts are made of metal. The simple flange design has the advantages that the water and the metal bolts are isolated completely, so that impermeable, leakage-proof and rust-proof effects are achieved when the water supply and drainage pipe passes through the geomembrane.
Description
Technical field
The invention belongs to the E section fixed buildings water supply and drainage class technical field of International Classification of Patents IPC, relate to a kind of antirust design of antiseepage of flange, specifically the antirust design of antiseepage of water supply and sewerage pipeline flange when crossing geomembrane.
Background technique
When at present the drainage pipeline of man-made lake is by geomembrane, between geomembrane and the pipeline be connected and antiseepage generally adopts the part to kink the method for binding, brushing emulsified pitch.The connection of this form and anti-seepage method, poor to the adaptability of the problems such as connection part distortion sedimentation, throw off easily in the runtime, become the potential weak link of leaking.
Summary of the invention
The purpose of this invention is to provide a kind of water supply and sewerage pipeline and cross the antirust flange design of antiseepage of geomembrane, so that this flange is when water supply and sewerage pipeline is crossed geomembrane, the metal screw is not subject to the corrosion of water, make simultaneously the pipeline can seepage at this place, solved seepage and the etching problem of pipeline at flange.
Technological scheme of the present invention is: add respectively a protective hat at the screw bolt and nut place of flange, then by sweat soldering so that metal bolts and water body keep apart, thereby guarantee structure antiseepage, leakproof and the rust-proof effect of this position, and make metal bolts be difficult for getting rusty, prolong its working life.It is characterized in that overlapping respectively a protective hat at head and the nut location of each bolt of fastening flange, then by sweat soldering itself and water body are kept apart; The material of protective hat is taken from pipeline material, namely intercepts the tubing that the segment radius is slightly larger than the bolt head radius, and the lid welding that a side adds same material gets final product.Wherein water supply and sewerage pipeline material, flange material, protective hat material are identical, are PVC or PE, and bolt is metallic material.
Effect of the present invention and benefit have provided a kind of easy flange design method, water body and metal bolts are kept apart fully, thereby solved antiseepage, leakproof, the antirust problem of water supply and sewerage pipeline by geomembrane the time.
Description of drawings
Fig. 1 is the flange arrangement schematic representation.
Fig. 2 adds the forward and backward flange arrangement schematic representation of protective hat.
Black triangle is the fill area soldering point among the figure, and the flange intermediate portion is plastic pad and geomembrane.
Embodiment
Be described in detail the specific embodiment of the present invention below in conjunction with technological scheme and accompanying drawing.
In this structure, except screw bolt and nut was metallic material, all the other were the multi-form of same material.
At first prepare protective hat, protective hat be by the sheet material of same material and tubing through being welded, according to the size of flange bolt, intercepted length and slightly larger in diameter weld together in the sheet material of the tubing of bolt and the respective diameters method by hot melt, both protective hat.
Mounting flange tights a bolt.
Protective hat is placed on the nut, with the method for hot melt protective hat and flange plate are welded together, thereby with bolt and water body isolation.
Claims (1)
1. antirust flange design of antiseepage that water supply and sewerage pipeline is crossed geomembrane is characterized in that overlapping respectively a protective hat at head and the nut location of each bolt of fastening flange, then by sweat soldering itself and water body is kept apart; The material of protective hat is taken from pipeline material, namely intercepts the tubing that the segment radius is slightly larger than the bolt head radius, and a side adds the lid welding of same material; Wherein water supply and sewerage pipeline material, flange material, protective hat material are identical, are PVC or PE, and bolt is metallic material.
