Embodiment Construction

[0013] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0014] figure 1 The reference numbers in the drawings are: steel pipe 1; glass concrete 2.

[0015] Such as figure 1 As shown, a steel pipe glass concrete member includes a steel pipe 1 filled with glass concrete 2 .

[0016] Such as figure 1 As shown, the glass concrete 2 includes the first waste glass with a particle size of 0.15-2.36 mm and the second waste glass with a particle size of 5-25 mm.

[0017] Such as figure 1 As shown, the first waste glass and the second waste glass are mixed at a mass ratio of 1:2.

[0018] Such as figure 1 As shown, both ends of the steel pipe 1 are closed.

[0019] The steel pipe glass concrete component provided by the present invention has a wide range of applications, mainly used as compression components, such as power transmission and transformation components, single-layer or multi-layer industri...

Abstract

The invention relates to compound pipes, in particular to a glass reinforced plastic pipe concrete member amongst the compound pipes. The glass reinforced plastic pipe concrete member comprises a steel pipe filled with glass concrete. The glass reinforced plastic pipe concrete member has the advantages that waste glass is applied to concrete filled steel tubes, the steel tubes provide tightening force for core glass concrete, the defect of expansion cracking of the glass concrete due to alkali-silica reaction is overcome; the core concrete generate different degrees of contraction stresses to cause cracking of the concrete, adding expanding agent to the concrete filled steel tubes to compensate the contraction stress of the core concrete conventionally is an existing way, the contraction stress of the concrete can be compensated to a certain degree by expansive force of the glass concrete caused by alkali-silica reaction of the glass concrete, and potential advantages of the waste glass can be given to play.

Description

technical field [0001] The invention relates to a composite pipe, in particular to a steel pipe glass concrete member in the composite pipe. Background technique [0002] For a long time, my country's economic development model has been resource-consuming. In addition, my country is in a period of vigorous economic development, and industrial production will produce more and more solid waste—waste glass, waste rubber, and municipal solid waste incineration ash. Therefore, , Recycling these solid wastes has important practical significance for resource conservation and environmental protection in our country. [0003] In recent years, with the continuous development of my country's economy, glass has been more and more used in people's production and life. At the same time, along with industrial production and people's life, more and more waste glass has been produced. According to the survey, my country's annual waste glass is more than 2 million tons, and the recycling rate...
