Guardrail used for underground complex and having submersion-resistant water drainage function

Abstract

The invention relates to the field of urban underground road engineering and the technical field of public facilities, in particular to a guardrail used for an underground complex and having a submersion-resistant water drainage function. The guardrail comprises a concrete main body, water drainage holes, a silica gel sponge combination bodies, a guardrail installation hole, a bolt, a water drainage groove, a water drainage pipeline, a spring net, a sponge mat, a silica gel mat, a buffer, an energy reducing plate, a comprehensive pipe gallery and a rainwater pipeline. Two sides of a side surface of a lower part of the concrete main body and two edges of an upper part of the concrete main body are provided with the water drainage holes, and two sides of a side surface of the upper part are provided with the silica gel sponge combination bodies; a hollowed-out part inside the concrete main body is the water drainage groove, and the water drainage groove does not penetrate through the concrete main body; a position which is arranged below the middle of the concrete main body and connected with the water drainage groove is provided with a water drainage pipeline. According to the guardrail, the structure is simple, the construction is convenient, the construction cost is low, the industrial disassembly is quite convenient, manual operation is not required, water can be automatically drained, and the guardrail is convenient to produce, easy to install and beneficial to promoting industrialization process.

Description

technical field [0001] The invention belongs to the field of urban underground road engineering and the technical field of municipal facilities, in particular to a guardrail with flood prevention and drainage functions for underground complexes. Background technique [0002] At present, urban transportation construction is in full swing. As the country further promotes the strategy of comprehensive pipe corridors and sponge cities, large and medium-sized cities in my country will surely set off a new round of climax in underground engineering construction. Due to the scarcity of underground space, the collection of "urban underground comprehensive pipe corridors" , urban underground expressways, and urban underground building space” are in great demand. [0003] The development and construction of underground space in Japan, Europe and the United States is in a leading position. It was the first to advocate and propose the concept of comprehensive and three-dimensional develo...

AI Technical Summary

Problems solved by technology

[0004] Nowadays, the construction of underground space is in full swing, and a large number of underground transportation, underground pipe corridors, etc. have been put into use. Compared with the ground, the comprehensive pipe corridor is a relatively airtight space, so once a disaster occurs in the comprehensive pipe corridor, such as floods, a large number of floods will instantly Flooding into the comprehensive pipeline corridor will bring more serious harm to people than on the ground, causing serious personal and property damage. When the flood floods into the underground transportation layer, it cannot be discharged in time, and people will be exposed to flood among them, endangering people's lives
