Abstract

The invention discloses an anticorrosion structure for the inner wall of a concrete pipeline. In the manufacturing process of the concrete pipeline (1), the inner wall of the pipe is lined with an anticorrosion coiled material (2), and then the anticorrosion coiled material and the concrete pipeline are formed into an integrated component through pouring of concrete. The diameter of the concrete pipeline (1) needs to be larger than or equal to 1.5 m. The anticorrosion coiled material (2) is an HDPE geomembrane, the thickness of the anticorrosion coiled material is larger than or equal to 2.0 mm, the width of the anticorrosion coiled material is larger than or equal to 3.0 m, and a sweat soldering connecting mode is adopted. One side of the anticorrosion coiled material (2) is a smooth plane, the other side of the anticorrosion coiled material is provided with rivets (3) made of HDPE materials, 1200 rivets are arranged on the anticorrosion coiled material (2) per square meter, and the height of each rivet head is 10 mm. The anticorrosion coiled material (2) for lining has the advantages of resisting corrosion, acid, alkali and salt, and therefore the inner wall of the concrete pipeline (1) is protected and the service life of the concrete pipeline is prolonged.

Description

A kind of inner wall anti-corrosive structure of concrete duct
Technical field
The present invention relates to a kind of anticorrosion structure, especially relate to a kind of inner wall anti-corrosive structure of concrete duct.
Background technique
The underground blowdown pipe network of municipal administration, large-scale wastewater treatment plant and various chemical plant underground pipe network adopt concrete duct to carry out the conveying of various liquid mediums more, due to the liquid medium complicated component of carrying, the risk that long-play concrete duct inwall is corroded is higher, thereby affects the working life of pipeline.
Therefore, need at the inwall of concrete duct, anticorrosion structure be set for this corrosion phenomenon.
Summary of the invention
The object of the present invention is to provide a kind of inner wall anti-corrosive structure that effectively prevents liquid medium corrosion concrete pipeline.
To achieve these goals, the technical solution used in the present invention is: in the working process of concrete duct (1), the inwall that a kind of anti-corrosion coiled material (2) is lining in to pipeline becomes an integrated member by concrete building with concrete duct.
Answer >=1.5m of described concrete duct diameter.
Described anti-corrosion coiled material is HDPE geomembrane, thickness >=2.0mm, width >=3.0m.
Described anti-corrosion coiled material adopts sweat soldering mode to connect.
Described anti-corrosion coiled material one side is smooth flat, and another side is provided with the rivet (3) of HDPE material, and number of rivets is 1200 of every square meter anti-corrosion coiled materials.
The high 10mm of ailhead of described rivet.
The invention has the beneficial effects as follows: described anti-corrosion coiled material has feature corrosion-resistant, acidproof alkali salt its acid resistant alkali scope PH2～12; Described anti-corrosion coiled material is installed on the inwall of concrete duct, can completely cut off fed sheet of a media and directly contact with concrete duct, thereby protection concrete duct is not corroded by the external world, extends pipeline working life; The anti-corrosion coiled material smooth surface of selecting, medium is difficult for being trapped on concrete duct inwall, very convenient for the cleaning of concrete duct.
Brief description of the drawings
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is the inner wall anti-corrosive structural representation of a kind of concrete duct of the present invention.
1. concrete ducts in figure, 2. anti-corrosion coiled material, 3. rivet.
Embodiment
As shown in Figure 1, embodiment is as follows:
In the time that concrete duct (1) is made, according to its length and inner circumference size cutting a slice with big or small anti-corrosion coiled material (2), adopt sweat soldering mode that anti-corrosion coiled material (2) is welded into a sleeve, the smooth one side of sleeve is close to concrete inner mould plate and is installed, be provided with HDPE material rivet (3) facing to concrete outer moulding board, then carry out concreting, wherein rivet one side is fixed in concrete, and anti-corrosion coiled material after maintenance moulding (2) becomes an integrated member closely with concrete duct (1).
