Embodiment

[0026] A concrete pipe lined with an elastic plastic sheet, such as figure 1 , figure 2 As shown, it includes a lining elastic plastic sheet 2 and a concrete structure layer 1 wrapped outside the lining elastic plastic sheet 2. The lining elastic plastic sheet 2 is composed of a base layer 4 and an elastic layer 3, and the base layer 4 is on the inside , the elastic layer 3 is on the outside, used to contact with the concrete structure layer 1, and an anchoring structure is arranged on the outside of the lining elastic plastic sheet 2, and the anchoring structure extends into the concrete structure layer 1, so that the lining elastic plastic sheet 2 It is firmly combined with the concrete structure layer 1 and has better sealing performance.

[0027] Wherein, along the length direction of the lining elastic plastic sheet 2, the anchoring structures are arranged at intervals with a distance of 5cm-20cm, and along the circumferential direction of the lining elastic plastic she...

Abstract

The invention relates to a concrete tube with a lining elastic plastic sheet. The concrete tube comprises a lining elastic plastic sheet and a concrete structure layer wrapping the outer side of the lining elastic plastic sheet, the lining elastic plastic sheet is composed of a base body layer and an elastic layer, the base body layer is arranged on the inner side, the elastic layer is arranged onthe outer side and is used for being in contact with the concrete structure layer, an anchoring structure is arranged on the outer side of the lining elastic plastic sheet, and the anchoring structure extends into the concrete structure layer, so that the lining elastic plastic sheet materials and the concrete structure layer are firmly combined, and better sealing performance is achieved. The anchoring structure consists of a connecting section and an anchoring section, the connecting section is directly connected with the lining elastic plastic sheet, and the anchoring section is directly connected with the connecting section. Compared with the prior art, the concrete tube has the advantages of being good in sealing effect, long in service life, good in anti-corrosion effect, and low inmaintenance cost; and the service life of the concrete tube can be obviously prolonged by 10-20 years.

Description

technical field [0001] The invention relates to a concrete pipe structure, in particular to a concrete pipe lined with an elastic plastic sheet. Background technique [0002] When the concrete pipe is used in the sewer or other corrosive environments, the drainage pipe will be eroded and damaged by corrosive gases such as hydrogen sulfide, which will greatly shorten the service life of the concrete pipe and even cause engineering problems. Therefore, the service life of traditional concrete pipes is short and the maintenance cost is high. At present, in view of the shortcomings of concrete pipes that are not resistant to corrosion, polymer materials are often used as the lining structure to reduce the corrosion of concrete pipes. [0003] Invention patent CN101109219A reports "concrete wall plastic liner". This patent discloses a plastic sheet with several protrusions. The protrusion structure combines the plastic lining pipe with the concrete wall, thereby providing anti-...
