Embodiment 1

[0016] attached figure 1 and figure 2 , and the two accompanying drawings show the specific structure of Embodiment 1 of the composite pipe material for constructing the sponge city proposed by the present invention. The composite pipe includes a base pipe 1, a cylindrical through hole 2, an inner anti-corrosion layer 3, an outer anti-corrosion layer 4, a permeable membrane 5 and a connecting piece 6, wherein the cylindrical through hole 2 is arranged on the upper half of the base pipe 1 Inside and through the pipe wall, the inner anti-corrosion layer 3 is arranged on the inner surface of the base pipe 1 and extends to the inner surface of the cylindrical through hole 2, and the outer anti-corrosion layer 4 is arranged on the outer surface of the base pipe 1 , the surface of the upper part of the outer anti-corrosion layer 4 is provided with a permeable membrane 5, that is, the permeable membrane 5 covers the outside of the columnar through hole 2, and the inner anti-corrosi...

Embodiment 2

[0018] see image 3 , gives the specific structure of Embodiment 2 of the composite pipe material for constructing the sponge city proposed by the present invention. The difference between this embodiment and the first embodiment is that the connecting piece 6 is formed by a flared port arranged on one side of the pipe end for socket connection, and other structures are the same as those of the first embodiment.

[0019] The present invention can absorb the accumulated water on the ground, filter the infiltrated accumulated water on the surface through the permeable membrane 5, and infiltrate the filtered accumulated water into the pipe for storage or transportation through the columnar through hole 2. It has the functions of filtering water, It has the characteristics of water seepage, water storage and hydrophobicity, and has strong corrosion resistance. At the same time, the connection between the pipes can be more conveniently connected through the connector 6, and the ant...

Abstract

The invention relates to a composite tubular product for constructing a sponge city. The composite tubular product comprises a base pipe and columnar through holes which are uniformly formed in the upper-half pipe wall of the base pipe, wherein inner anticorrosion layers are arranged on the inner surfaces of the base pipe and the columnar through holes, and outer anticorrosion layers are arrangedon the outer surfaces of the base pipe. According to the composite tubular product, water accumulated on the surface of the ground can be eliminated on the spot, and the composite tubular product hasthe characteristics of being capable of filtering, seeping, accumulating and eliminating water; the water accumulated on the surface of the ground can be collected in the rainy season, so that the rainfall flood can be reduced; the accumulated water can be reutilized in the dry season; and the composite tubular product completely meets the demands on the construction of the sponge city and has relatively strong corrosion resistance, meanwhile, the tubular products can be conveniently connected through connecting components, and the anticorrosion layers at the ends of the base pipes can be protected, so that a very ideal technical effect can be achieved in the construction process of the sponge city or the treatment process of saline-alkali soil.

Description

technical field [0001] The invention relates to a composite pipe for constructing a sponge city. Background technique [0002] In recent years, due to climate change and the weakening of environmental carrying capacity, the situation of "waterlogging every rain and drought after rain" often occurs, making my country's urban water ecology face two extremes: on the one hand, urban waterlogging during the rainy season Seriously, rain and flood management has become a safety hazard affecting urban development; on the other hand, most cities suffer from severe water shortages during the dry season, and water supply is seriously insufficient. It also brings a series of problems such as shortage of water resources, water environment pollution, and lack of guarantee of water safety. With the development of social economy and the frequent occurrence of urban rain and flood disasters, cities have higher and higher requirements for drainage projects. Therefore, in order to maintain the...
