Problems solved by technology

[0002] The water supply and drainage pipelines laid underground are damaged due to changes in geological structure, ground subsidence, pressure of buildings above the pipelines and long-term erosion of various corrosive substances on the pipelines, and many pipelines have been built above Buildings can no longer be excavated
Especially the repair and transportation of large-diameter underground pipelines are very difficult

Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0023] figure 1 It is a schematic diagram of the structure of the modular FRP pipeline. It can be seen from the figure that it is a circular pipe, and the circular pipe is composed of pieces of arc-shaped sheet modules 1 spliced ​​with each other in the circumferential direction and the axial direction respectively.

[0024] The arc-shaped sheet module 1 is a quadrilateral such as Figure 1 to Figure 6 As shown, the opposite sides of one pair of arcs have the same curvature as the circular pipe, and the other pair of opposite sides are straight lines. Described sheet-like module is shaped on the lap edge 2 that is spliced ​​with each other all around, forms the form splicing of lap joint between adjacent sheet-like module 1 such as Figure 7 shown. The lap 2 is the lap 2 on the outer surface of the pipe enclosing the inner surface of the pi...

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 [0001] The invention relates to a liquid transportation pipeline, in particular to a modular glass fiber reinforced plastic pipeline buried underground for liquid transportation and a repair method for the buried damaged pipeline. Background technique [0002] The water supply and drainage pipelines laid underground are damaged due to changes in geological structure, ground subsidence, pressure of buildings above the pipelines and long-term erosion of various corrosive substances on the pipelines, and many pipelines have been built above Buildings cannot be excavated for construction. Especially the repair and transportation of large-diameter underground pipelines are very difficult. Contents of the invention [0003] The purpose of the present invention is to provide a modular FRP pipeline with corrosion resistance, high strength, small flow resistance, convenient repair and construction of damaged pipelines, and low transportation cost and its repair met...
