Abstract
The invention discloses a modular glass steel pipeline and a method for repairing an underground broken pipeline by using the same, and aims to provide a modular glass steel pipeline which is high in corrosion resistance and strength, and low in flow resistance and transportation cost, and repairs and constructs a broken pipeline conveniently, and a method for repairing an underground broken pipeline by using the same. The modular glass steel pipeline is a circular pipeline, and is characterized in that: the circular pipeline is formed by splicing arc-shaped flake modules in circumferential and axial directions respectively. The repairing method comprises the following steps of: using a modular glass steel pipeline of which an outer diameter is smaller than that of an inner hole of the broken pipeline, and splicing the flake modules into the modular glass steel pipeline in a repairing pipeline; and injecting cement mortar into a gap between two pipe walls to fix the pipeline. By the pipeline and the method, although an inner diameter of the repaired pipeline is smaller than the original inner diameter, excavation is avoided. The modular glass steel pipeline has the advantages of low flow resistance, corrosion resistance, long service life, low cost and the like, is convenient to transport, and is particularly suitable for repair engineering of waste pipelines.
Description
Technical field
The present invention relates to the conveyance conduit of liquid, particularly a kind of restorative procedure that is embedded in underground Modular glass fiber reinforced plastics pipeline for the liquid conveying and is used for buried broken pipe.
Background technique
Be laid on underground water supply and sewerage pipeline because variation, the surface subsidence of geologic structure, the pressure-bearing of pipeline top building and the long-term erosion of various corrosive goods confrontation pipelines, cause the water supply and sewerage pipeline of laying damaged, build thing and just can't excavate again to build and repair and built for many pipelines top.Especially bigbore under ground piping reparation and transportation are very difficult.
Summary of the invention
The purpose of this invention is to provide a kind of corrosion-resistant, intensity is high, flow resistance is little, to reparation and the easy construction of broken pipe, the Modular glass fiber reinforced plastics pipeline that cost of transportation is low and be used for the restorative procedure of buried broken pipe.
In order to reach above-mentioned requirements, the present invention is achieved by the following technical solutions: it is a kind of circular pipe, it is characterized in that described circular pipe is spliced at circumferential and axial respectively mutually by the sheet module of blocks of arc to form.
The sheet module of described arc is quadrilateral, and wherein the opposite side of a pair of arc is identical with the curvature of circular pipe, and another is straight line to opposite side.
Be shaped with the scrap (bridge) of mutual splicing around the described sheet module, become the form splicing of overlap joint between the adjacent sheet module.
Described scrap (bridge) is for encasing the scrap (bridge) of inner surface of pipeline at the scrap (bridge) of pipeline external surface.
Be shaped with attachment hole on the described scrap (bridge), connecting pin or attachment screw are installed in the attachment hole, connecting pin or attachment screw are fixedly connected with adjacent sheet module.
Described sheet module is made by the glass fiber resin concrete.
Utilize above-mentioned Modular glass fiber reinforced plastics pipeline to the restorative procedure of buried broken pipe, to use external diameter less than the Modular glass fiber reinforced plastics pipeline of pipe-repairing endoporus, in pipe-repairing, piece of sheet module is spliced into Modular glass fiber reinforced plastics pipeline, and the cementing mortar is fixed in the space between two tube walls.
Modular glass fiber reinforced plastics pipeline according to the such scheme manufacturing, because it is to have the sheet module of an arc mutually to be spliced at circumferential and axial, therefore when being embedded in the underground pipeline rehabilitation of having damaged, can use external diameter less than the sheet module formula fiber reinforced plastic pipe of pipe-repairing endoporus, in pipe-repairing, piece of sheet module is spliced into Modular glass fiber reinforced plastics pipeline, and slip casting is fixed between two tube walls, reaches the purpose of reparation.Although the internal diameter of the pipeline after repairing reduced to some extent than originally, had avoided excavation, and can not impact flow velocity owing to the smooth flow resistance of tube wall is little.Modular glass fiber reinforced plastics pipeline has that flow resistance is little, corrosion-resistant, the convenient transportation low cost and other advantages, is particularly suitable in the reinstatement works of waste and old pipeline.

Embodiment
The invention will be further described below in conjunction with the drawings and specific embodiments.
Fig. 1 is the structural representation of Modular glass fiber reinforced plastics pipeline.As seen from the figure, it is a kind of circular pipe, and described circular pipe is mutually spliced at circumferential and axial respectively by the sheet module 1 of blocks of arc and forms.
The sheet module 1 of described arc is that quadrilateral such as Fig. 1 are extremely shown in Figure 6, and wherein the opposite side of a pair of arc is identical with the curvature of circular pipe, and another is straight line to opposite side.Be shaped with the scrap (bridge) 2 of mutual splicing around the described sheet module, become the form splicing of overlap joint between the adjacent sheet module 1 as shown in Figure 7.Described scrap (bridge) 2 is for encasing the scrap (bridge) 2 of inner surface of pipeline at the scrap (bridge) 2 of pipeline external surface.Be shaped with attachment hole 3 on the described scrap (bridge) 2, connecting pin 4 is installed as shown in Figure 8 in the attachment hole 3 or attachment screw 5 as shown in Figure 9, connecting pin 4 or attachment screw 5 are fixedly connected with adjacent sheet module 2.Described sheet module 2 is made by the glass fiber resin concrete.
Utilize above-mentioned Modular glass fiber reinforced plastics pipeline to the restorative procedure of buried broken pipe, to use external diameter less than the Modular glass fiber reinforced plastics pipeline of pipe-repairing endoporus, in pipe-repairing, 2 pieces of sheet module are spliced into Modular glass fiber reinforced plastics pipeline, and the cementing mortar is fixed in the space between two tube walls.
