As shown in Figure 1, the pipe for escaping that the globality and airtightness of the utility model enhance, including pipe for escaping tube body 1,
Water-proof strip 2 and connector 9, adjacent 1 paper of pipe for escaping tube body are closely connected by water-proof strip 2 and connector 9, this covering device
The safety guarantee to tunnel construction personnel will be improved, and played a protective role to tunnel pipe for escaping internal environment, moreover it is possible to
It effectively prevent external water to leak out in tube body, when preventing construction personnel from encountering disaster, obstruction is generated to personnel escape's route.
As shown in Fig. 2, 1 two ends working process of pipe for escaping tube body is processed into a step surface 1.1, it is anti-to facilitate
The installation of the assembled and subsequent connector 9 of water bar 2.Mounted pipe for escaping is placed between face and two linings
Between position, after pipe for escaping places, the linkage section of pipe for escaping tube body 1 is wrapped up using water-proof strip 2, makes two sections
Pipe for escaping tube body 1 has good linking, then through connector 9 together with connection bolt 6 is by the anchoring of two segment pipes.
Water-proof strip 2 generally uses rubber strip, and when installation is spliced, the splicing for water-proof strip 2 can smear at end matching
The dedicated high-strength solid of one layer of rubber keeps water-proof strip 2 and 1 end of pipe for escaping tube body closely connected.It can be adopted in 2 joint of water-proof strip
It is attached with cold bonding method or hot melt.
As shown in Figures 3 and 4,2 cross section of water-proof strip of use is T-shaped, and water-proof strip 2 includes upper and bottom section, lower part
Divide and is connected as one with upper part.The upper long 50mm of segment rectangle, wide 10mm, the lower long 20mm of segment rectangle, wide 10mm, thickness with
Pipe for escaping thickness just agrees with.Lower part rubber water-proof item plays the role of second defence line, holds in the mouth the end of two sections of escape tubes
It connects even closer.Mountable 5 to 6 connectors 9 on the same section in end junction, to increase the airtightness waterproof of junction
Property.Water-proof strip is equipped with two ways:
The first: lower part quartile is between the end of adjacent pipe for escaping tube body 1, and top quartile is in adjacent escape tube
On the step surface 1.1 of road tube body 1.After final water-proof strip 2 is installed, it is consistent with the periphery of pipe for escaping tube body 1.
Second: lower part quartile on the step surface 1.1 of adjacent pipe for escaping tube body 1, escape in adjacent by top quartile
On the outer surface of raw pipeline tube body 1.
As shown in Fig. 5~7, connector 9 includes two intermediate plates and connection bolt 6, and two intermediate plates are connected by connection bolt 6
Get up, each intermediate plate includes the first connecting plate 4.1, the second connecting plate 4.2 and reinforces connecting plate 4.3, in the first connecting plate 4.1
On open there are two bolt hole 3, opened on the second connecting plate 4.2 there are four connecting hole, the second connecting plate 4.2 by four bolts and
Pipe for escaping tube body 1 is connected, and fixes its position, then connects bolt 6 with two stay bolts and opposed two first are connected
Plate 4.1 links together, and tightens nut 5.1.After having connected one week bolt, just two sections of pipe for escaping tube bodies 1 are connected to
Together.
Intermediate plate generally selects steel disc, and connection effect is preferable.
Water-proof strip 2 is T-bar shape object, is spliced in the centre of two sections of pipe for escaping tube bodies 1.Water-proof strip 2 is being wound before splicing
Place smear a certain amount of rubber adhesive special, keep water-proof strip 2 and tube body closely connected, then with hot melt or binder general
Rubber strip end links together.After the completion of water-proof strip 2 splices, in conjunction with Fig. 7 and Fig. 8, two intermediate plates are first mounted on diagram
Position is fixed using bolt, after installing a circle intermediate plate, the intermediate plate that two are opposed is linked together using connection bolt 6, is twisted
It fastens, keeps water-proof strip 2 and 1 tube body of pipe for escaping tube body more closely connected.
It is the pipeline that connector 9 is mounted on to 1 end step surface rear of pipe for escaping tube body first when installation connecting element 9
Surface, then two intermediate plates are linked together by connecting bolt 6, tighten fixation.
As shown in figure 9, usually not using or being not used as construction ventilation pipeline after pipe for escaping is installed
When, a protecting cover 7 can be covered in tip position, with protective conduit internal environment.
As shown in Figure 1, placing certain amount according to demand for security below pipe for escaping after pipe for escaping assembly is completed
Timber wedge block 8.As shown in Figure 10, it is provided with groove body on timber wedge block 8, using curved timber wedge block, to prevent pipe for escaping tube body 1 from existing
It is rolled in hole, influences the construction in hole, while more providing safeguard for the life security of construction personnel.And curved wood
Voussoir avoids the contact of connector 9, water-proof strip 2 with earth's surface, prevents from generating corrosion or corruption to them due to water or other substances
Erosion.Can timber wedge block 8 when installation or after being installed, be placed on the downside of pipe for escaping, avoid the transverse direction of pipeline
It rolls.
After entire pipe for escaping is installed, the abutment wall lower position between face and two linings is placed it in.It is flat
When do not use, covered with protecting cover 7 in end, protect the environment inside pipe for escaping.When tunnel tunnel face nearby occurs
When collapsing, construction personnel should be run immediately toward pipe for escaping end, open protecting cover 7, creep into pipe for escaping hedging, to not collapsing
Place creep, to ensure personal safety.
The attachment device is first pre-processed in factory, is transported to engineering department after processing is completed and is carried out in-site installation.Engineering
After construction is completed, can bolt on first dismantling connection part 9, then water-proof strip 2 is removed, thus the dismantling of entire pipe for escaping.
Secondary use, environment friendly and economical can be carried out by disassembling complete component for these.
The attachment device of the utility model integrates connection and protection, and installation is easy to operate, convenient, and cost is relatively low,
It is readily disassembled simultaneously, it can be into Reusability.Not only waterproof can also effectively avoid the fugitive dust in work progress from entering pipeline to the present apparatus
Inside is effectively protected pipe for escaping internal environment.Simultaneously because pipeline, can also be used as and construct by the good airtightness of device
The ventilation shaft of journey.In addition, having added a certain number of timber wedge blocks 8 in pipeline lower part, the random rolling of pipeline can be prevented, reduction is escaped
Pipeline is given birth to for the obstruction of construction, while having ensured the safety of construction personnel to a greater degree.
