Intelligent large-caliber comprehensive culvert pipe in city

Abstract

The invention relates to an intelligent large-caliber comprehensive culvert pipe in a city. The culvert pipe is a round pipe, the diameter of the cross section of the culvert pipe is larger than 4 m, and the culvert pipe comprises a pipe wall and a framework arranged inside the pipe wall; and the pipe wall sequentially comprises a first fiber cloth layer (1), a basalt fiber rib framework layer (2) and a second fiber cloth layer (3) from the inner layer to the outer layer. The pipe wall and the framework arranged inside the pipe wall are formed by chopped-fiber-strengthened magnesium oxychloride cement in an integral pouring manner. The intelligent large-caliber comprehensive culvert pipe is mainly used for a buried pipe, the properties such as mechanical strength, fire prevention, heat isolation and preservation and environmental protection of a common round culvert pipe are improved, large size and multi-functionalization of the caliber of the culvert pipe are achieved, and the requirement of inland municipal construction and national defense construction for fire prevention, water prevention, heat preservation and heat isolation of the large-caliber culvert pipe and the culvert pipe can be met.

Description

technical field [0001] The invention relates to an urban intelligent large-diameter comprehensive culvert pipe, which is used for buried pipes underground and integrates drainage, gas pipes, tap water pipes, heating pipes, communication cables (optical cables) and underground cables. Background technique [0002] Culvert pipes are widely used in water conservancy, highways, railways, and municipal projects. With the development of domestic municipal construction and national defense construction, a large number of large-diameter drainage pipes are required. When the original GB11836-89 standard was formulated, the diameter of the drainage pipes ranged from Φ200mm to Φ2400mm, and when the GB11836-99 standard was formulated, according to the investigation, the diameter range has been extended to Φ200mm~Φ3000mm, and even some projects have used pipes above Φ3000mm. For the drainage pipe industry, the current small-diameter pipe market has been strongly impacted by various plast...

From the perspective of product raw materials, raw materials with low energy consumption and little or no environmental pollution should be used as much as possible. However, the current mainstream raw material is ordinary Portland cement. Portland cement is both a large energy consumer and a large pollutant discharger. According to statistics, Producing 1 ton of cement will emit 1 ton of CO 2 , but also to emit dust and other harmful gases

[0004] At present, the culvert pipes are generally buried underground for the confluence and drainage of waste water. Various underground lines can also be installed in the culvert pipes, and the lines are fixed at different axial positions in the culvert pipes by fasteners. Waste water is easy to corrode the circuit and cause damage to the circuit. When removing the entire circuit, it is necessary to remove all the buckles first. This will cause inconvenience in the maintenance of the circuit, which needs to be improved urgently
