Technical field
The utility model is related to the realm of building construction, espespecially a kind of tunnel escape device.
Background technology
In the construction of newly built tunnels, because geological state is complicated and changeable, there is the possibility of landslide, construction in work progress
The accident of casualties occurs in personnel if it can not flee from time.
According to current highway engineering construction safety technical specification, Support System in Soft Rock Tunnels is excavated face to two linings and must be provided with
Passway for escaping, as face constantly moves forward, passway for escaping from cannot be greater than 20 meters with a distance from face, the rigidity of passway for escaping,
Intensity, impact capacity should meet safety requirements, and passway for escaping is difficult to be less than 0.8m.
Given a lesson to according to previous experiences, escape tubular type passway for escaping is only applicable to the face rear in the tunnel and caved in thing
Therefore when workmen be trapped in hole ideally, escape tube be trapped personnel conveying air, food and relief goods or
Voluntarily withdrawn from passage.
But actual weak tunnel is in digging process, the probability that face unstability is caved in is much larger than face rear unstability
The probability caved in, and the space that the personnel operated in this case in face almost do not survive, if workmen can not
Flee from time, the accident of casualties occurs.

Embodiment
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
Refering to Fig. 1, it is shown that the structural representation of the utility model tunnel escape device.As shown in figure 1, the utility model
Tunnel escape device includes：Escape room 10 and escape tube 20, wherein, escape room 10 is at tunnel tunnel face, the tunnel face
Face is the working face constantly pushed ahead during tunnelling.Escape room 10 has been internally formed escape space.Escape room 10
Offer import 100 and outlet 101, import 100 is connected with escape space, escape tube 20 be installed in outlet 101 and with escape
Space is connected.The utility model tunnel escape device sets safe escape room at face, and escape room is communicated with escape tube,
When face unstability is caved in, escape room provides a closing, interim safety for the operating personnel of construction below face and protected
Place, to starting rescue, time enough is striven in work.
Refering to Fig. 2, it is shown that the utility model tunnel escape device side view.Refering to Fig. 3, it is shown that the utility model tunnel
The front view of road escape device.With reference to shown in Fig. 1 to Fig. 3, escape room 10 is cylindrical structure, and the top of cylindrical structure is arc point
End.When tunnel surrounding caves in, the area for receiving frontal impact greatly reduces, and the body that caves in runs into the backward escape in arc tip
The both sides in room and diffuse to form native arch, so in the case of equal material and size, using the cylindrical structure with arc tip
Than the pressure of more large impact can be born using rectangular parallelepiped structure.
Refering to Fig. 4, it is shown that A enlarged diagram in Fig. 3.With reference to shown in Fig. 3 and Fig. 4, escape room 10 is by multiple ripples
Steel plate unit 1020 is spliced.Using corrugated steel material compared to plane steel plate is used, impact of the corrugated portion to falling rocks has
There are bigger buffering and smaller deflection, it is not easy to destroyed by falling rocks.So in other words, under equal impact resistance,
Using corrugated steel material than the weight saving 50% using plane steel plate, the installation weight being so made is small, is more conducive to exist
Frequently moved in digging process.
Specifically, to obtain the suitable specification of corrugated steel, following experiment has been carried out：
Due to the impact resistance of mainly consider to escape when Tunnel Landslide room and escape tube, and pounded position and need satisfaction
The evacuation demand of personnel.The utility model tunnel escape device is subjected to field test.Impact test piece is block boulder, and weight is
1000KG.The utility model tunnel escape device is placed on sand bedding course, impact test piece mainly takes from escape room distance from top
Certainly in the excavation height of tunnel cross-section, such as, when the height of tunnel excavation is 8.45m, during a height of 2m in room of escaping, this is tested
Height be set to 7m, the height of stone test specimen is lifted by crane.In test, through measurement either middle part or end
Maximum distortion is respectively less than 150mm, fully meets escape and requires.Therefore the model of corrugated steel can be set to waveform 75mm ×
25mm, thickness of slab is 4mm.It is possible to more more severe than test situation in view of actual field situation, to obtain corrugated portion to falling
Stone impacts bigger buffering and smaller deflection, and bigger ripple 150mm × 50mm × 4mm will be selected during actual production.
With reference to shown in Fig. 3 and Fig. 4, the end of two neighboring corrugated steel unit 1020 is mutually overlapped, and passes through the first spiral shell
Bolt 30 is fixedly connected.Specifically, the crest and crest of two corrugated steel units 1020 is overlapped, trough and trough are mutual
It is overlapping, the first bolt 30 is worn to two overlapped troughs, and be screwed together on the first bolt 30 to fix using nut.
Specifically, escape room 10 import 100 located at cylindrical structure side middle part, escape room 10 import 100 with
Escape space is connected.In the present embodiment, the edge of import 100 is fixed with angle steel flange.So when face unstability is caved in,
The operating personnel of construction can be entered at the import 100 in escape room 10 in escape room 10 below face, and escape room 10 can
One closing, interim safety are provided with the operating personnel for construction below face and protect place, work is striven to starting rescue
Take time enough.
The outlet 101 in escape room 10 is located at one end for being relatively distant from face of cylindrical structure.Export to be communicated with 101 and escape
Raw pipe 20, the so operating personnel into escape room 10 can just go out at outlet 101 by escape tube 20.
Refering to Fig. 5, it is shown that B enlarged diagram in Fig. 3.With reference to shown in Fig. 3 to Fig. 5, the end in room 10 of escaping, ripple
The trough laminating of line steel plate unit 1020 is placed on the top of the end in escape room 10, the second bolt 40 is worn overlapped
The top of the end in trough and escape room 10, and be screwed together on the second bolt 40 to fix using nut.
The utility model tunnel escape device has the beneficial effect that：
The utility model tunnel escape device sets safe escape room at face, and escape room is communicated with escape tube,
When face unstability is caved in, escape room provides a closing, interim safety for the operating personnel of construction below face and protected
Place, to starting rescue, time enough is striven in work.The cross section in escape room is horseshoe type face, and the top in horseshoe type face is arc
Shape tip, when tunnel surrounding caves in, the area that arc tip receives frontal impact greatly reduces, and the body that caves in runs into
The both sides in the backward escape room in arc tip diffuse to form native arch, and the shape of a hoof can be held than rectangle in the case of equal material and size
By the pressure of more large impact.The side in escape room is formed using multiple corrugated steel unit spliceds, in equal impact resistance
Under, it is more many than the weight saving using general steel plate using corrugated steel, escape room is continually moved more conducively in digging process
It is dynamic.
The utility model is described in detail above in association with accompanying drawing embodiment, those skilled in the art can root
Many variations example is made to the utility model according to described above.Thus, some of embodiment details should not be constituted to this practicality
New restriction, the utility model regard the scope defined using appended claims as protection domain of the present utility model.
