Description
Technical field
The utility model relates to safety first-aid facility technology field more particularly to a kind of high-intensitive tunnel pipe for escaping knots
Structure.
Background technique
Tunnel in the construction process, is easy to happen to collapse and turns over accident, and tunnel collapses to turn over usually can all cause biggish personnel to hurt afterwards
It dies, and personnel are buried under the ground, it is difficult to sue and labour.Although theoretically constructing tunnel collapse accident of turning over can be to avoid,
Reason difficult to calculate is frequently encountered during practice of construction tunnel is caused to collapse and turned over, such as geological disaster, earthquake, construction wrong miss
The reasons such as operation cause tunnel to collapse to turn over.In order to maximally reduce casualties when tunnel collapses and turns over, usually set in tunnel
Pipe for escaping is set, tunnel collapses when turning over, and personnel enter pipe for escaping at the first time and escape, and pipe for escaping common at present has gold
Metal conduit, concrete duct etc..Metallic conduit weight is big, the time grown get rusty easily, poor corrosion resistance, cement pipe for escaping at
This is lower, and then weight is big, compressive property is poor, and safety coefficient is low, requires light weight, the intensity of pipe for escaping in the construction process
Many requirements such as high, corrosion-resistant, at low cost, it is clear that either metal pipe for escaping or cement pipe for escaping is unable to satisfy this
A little demands.
Utility model content
The utility model mentions to solve the problems, such as that pipe for escaping weight in tunnel in the prior art is big, compressive property is poor
Supply that a kind of light weight, compressive property be good, corrosion resistant high-intensitive tunnel pipe for escaping structure.
To achieve the goals above, the utility model adopts the following technical solution:
A kind of high intensity tunnel pipe for escaping structure, including tube body, one end of the tube body extend to form section of taking the lead, tube body
The other end extend to form plug section；The internal diameter of the section of taking the lead is greater than the outer diameter of plug section；The tube body from outside to inside according to
Secondary includes extexine, laminboard layer, endosexine, and the extexine, endosexine are frp layer, and the laminboard layer is resin
Haydite layer is bonded, the section of taking the lead, plug section are made of glass reinforced plastic；The inner wall of the endosexine is equipped with several convex annulars
Rib, the annular protruding rib are an integral structure with endosexine.Endosexine, extexine use frp layer, and glass reinforced plastic has good
Resistance to compression well, corrosion resistance；Laminboard layer is resin-bonded haydite layer, and resin-bonded haydite layer compressive property is good, density is small, pole
Big reduces overall weight；Section, the plug section of taking the lead are docked convenient for the grafting of two escape tubes, and integral construction is very convenient；Ring
On the one hand shape fin further increases whole radial crush resistance energy, while when escape tube is tilted and installed, existing for survivor
Climbing provides stress point in pipeline, is convenient for survivor's fast-escape.
Preferably, the cross section of the annular protruding rib is semicircle.Semicircle can reduce stress concentration, entire compression
It can be more preferable.
Preferably, being equipped with the glass fabric of several annulars in the section of taking the lead, plug section.Glass fabric can increase
Add the self-strength of section of taking the lead, plug section, so that section of taking the lead, plug section load performance be not good, easy to crack.
Preferably, the lateral surface of the plug section is male cone (strobilus masculinus), the medial surface of the section of taking the lead is inner conical surface, described outer
The conical surface, the taper of inner conical surface are equal；The plug section, section of taking the lead outer end be equipped with lifting bolt.When two escape tube connections,
The plug section of a piece escape tube is inserted into the taking the lead in section of another escape tube, after inner conical surface and male cone (strobilus masculinus) cooperation again by cable wire or
Iron chains connects lifting bolt, to fast implement being stably connected with for two escape tubes.
Preferably, the internal diameter of the tube body is 0.6m-1.2m, the wall thickness of the tube body is 2cm-4cm, the laminboard layer
Account for the 60%-80% of total wall thickness.Laminboard layer thickness accounting is very big, and laminboard layer density is smaller, to greatly alleviate whole weight
Amount.
Therefore, the utility model has that light weight, compressive property be good, corrosion resistant beneficial effect.
