Abstract
High temperature resistant subway segment and processing method thereof, belong to underground construction technology field, relates to a kind of subway segment and processing method thereof, particularly relates to a kind of novel fire resistant subway segment coping with complex environment and fire and processing method thereof.The present invention provides a kind of simple in construction, with low cost, simple for production, environmental protection, can the high temperature resistant and high temperature resistant subway segment of reinforcement and processing method thereof.The present invention includes concrete metro section of jurisdiction, is characterized in being provided with refractory masses on the inwall of described concrete metro section of jurisdiction, and described refractory masses uses aryl fiber cloth.Processing method: step one: laying one layer of aryl fiber cloth in advance inside the template of section of jurisdiction contact internal walls before formwork pours, and be fixed；Step 2: carry out pouring of concrete；Step 3: carry out curing conservation.
Description
Technical field
The invention belongs to underground construction technology field, relate to a kind of subway segment and processing method thereof, particularly relate to
A kind of novel fire resistant subway segment coping with complex environment and fire and processing method thereof.
Background technology
At present, underground traffic has become as the first-selection of people's traffic trip, is subject to so that it can quickly arrive at
The favor of the numerous common people, but also the problems such as ground traffic congestion can be alleviated.Existing subway segment, is substantially unified rule
Lattice make and come into operation, and meet the condition of a fire if prominent, can make the degeneration of concrete metro section of jurisdiction under high temperature, then fall slag damaged.Market
On lack a kind of not only can be high temperature resistant but also the high temperature resistant subway segment on surface, section of jurisdiction can well be protected.
Summary of the invention
The problem existed for prior art, the present invention provides a kind of simple in construction, with low cost, simple for production, green
Environmental protection, can the high temperature resistant and high temperature resistant subway segment of reinforcement and processing method thereof.
To achieve these goals, the present invention adopts the following technical scheme that a kind of high temperature resistant subway segment, including concrete
Subway segment, is characterized in being provided with refractory masses on the inwall of described concrete metro section of jurisdiction.
Described refractory masses uses aryl fiber cloth.
The processing method of described high temperature resistant subway segment, comprises the steps:
Step one: laying one layer of aryl fiber cloth in advance inside the template of section of jurisdiction contact internal walls before formwork pours,
And be fixed；
Step 2: carry out pouring of concrete；
Step 3: carry out curing conservation.
Beneficial effects of the present invention:
1, the high temperature resistant subway segment simple in construction of the present invention, with low cost, environmental protection, can be with Concrete Structure subway
The resistance to elevated temperatures of section of jurisdiction, even if Concrete At High Temperature degeneration, the aryl fiber cloth of its inwall still can protect concrete table
Face, has the effect of reinforcement；
2, the processing method of the high temperature resistant subway segment of the present invention is simple for production, easily realizes.
Accompanying drawing explanation
Fig. 1 is the structural representation of the high temperature resistant subway segment of the present invention；
In figure: 1-concrete metro section of jurisdiction, 2-refractory masses.
Detailed description of the invention
The present invention is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
As it is shown in figure 1, a kind of high temperature resistant subway segment, including concrete metro section of jurisdiction 1, in described concrete metro section of jurisdiction
Refractory masses 2 it is provided with on the inwall of 1；Described refractory masses 2 uses aryl fiber cloth, and described aryl fiber cloth is for fragrant
The fiber cloth that synthetic fibre fibrage becomes, described aramid fiber is produced by du pont company, and the kevlar fiber that the said firm produces is also
It it is exactly described aramid fiber.
The processing method of described high temperature resistant subway segment, comprises the steps:
Step one: laying one layer of aryl fiber cloth in advance inside the template of section of jurisdiction contact internal walls before formwork pours,
And be fixed；
Step 2: carry out pouring of concrete, owing to concrete itself has stickiness, can be good with aryl fiber cloth
Combine；
Step 3: after carrying out solidification and standard curing method maintenance, fire-resistant aryl fiber cloth is just and concrete ground iron pipe
Sheet 1 is well consolidated, and then can be transported to job site assembly and come into operation.
Claims (3)
1. a high temperature resistant subway segment, including concrete metro section of jurisdiction, it is characterised in that in described concrete metro section of jurisdiction
Refractory masses it is provided with on inwall.
High temperature resistant subway segment the most according to claim 1, it is characterised in that described refractory masses uses aramid fiber
Cloth.
3. the processing method of the high temperature resistant subway segment described in claim 2, it is characterised in that comprise the steps:
Step one: laying one layer of aryl fiber cloth in advance inside the template of section of jurisdiction contact internal walls before formwork pours, going forward side by side
Row is fixing；
Step 2: carry out pouring of concrete；
Step 3: carry out curing conservation.
