Abstract
The utility model relates to a kind of trestles with big section rescue run channel, including the main bridge being made up of two symmetrical box beams, individual passage is set in box beam, channel cross-section be it is round, inside set circular inner liner, liner bottom sets drainage hole, top sets ventilation hole, once there is a small amount of water to penetrate into box beam, water is discharged from box beam bottom, it can be ensured that the drying of escape route.Top portion ventilation hole can ensure that escape personnel's oxygen is sufficient.And the both ends open of box beam, including front opening and open rearward end；The section in channel can accommodate at least one adult and pass through.The utility model has the advantage of construction personnel is escaped to rear end from the front end of trestle by this emergency measure of channel or even flees from construction area, has accessible escape route；The rescue channel that the external world is formed by channel enters trestle front end and sues and labours, and improves rescue efficiency.
Description
Technical field
The utility model relates to a kind of trestles with the independent rescue run channel in big section, belong to tunnel or underground engineering
Technical field of concrete construction.
Background technique
With the progress of China's tunnel construction technology, the requirement to the mechanization of inverted arch construction is higher and higher, although at present
There is part of the manufacturer to be capable of providing mechanical inverted arch trestle, but there is trestle work structure complexity, investment is big, heavy, malfunction,
The disadvantages of security performance is not high not can be carried out the popularization of large area.In constructing tunnel, the section-bottom arc of excavation is referred to as
Inverted arch；And in the work progress at tunnel inverted arch position, inverted arch trestle need be set up in inverted arch excavation face, before being connected to tunnel
The excavation face at end and tunnel rear end fill surface channel, fill surface, that is, inverted arch carry out term when concrete construction, inverted arch trestle
In the presence of so that tunnel excavation slags tap to transport not applied by inverted arch into hole with material outward is influenced, inverted arch concrete construction ensure that
It continuously, is simultaneously carried out with tunnel excavation.But at present construction used in trestle Shortcomings, escape route in girder,
Because having gusset and partition inside girder, interim when surprisingly coming, when such as caving in, construction personnel escapes in the case where flurried, holds
Contingencies such as easily tripping or damage in escape route.
Utility model content
The purpose of this utility model is to provide a kind of trestles with big section rescue run channel, to overcome existing
The deficiency of technology.
The utility model is achieved through the following technical solutions, including the master being made up of two box beams in left and right crossbeam
Bridge, it is characterised in that；Any box beam be big sectional box-type beam, built-in big section escape route,
Liner is additionally provided in the big section escape route, the liner is circle, and liner bottom sets drainage hole, top
If ventilation hole, once there is a small amount of water to penetrate into box beam, water is discharged from the drainage hole of box beam bottom, it can be ensured that escape route
It is dry；The ventilation hole at top can ensure that escape personnel's oxygen is sufficient.
The diameter of section of the escape route is not less than 800mm, and clear in channel, can accommodate at least one adult
People quickly through.
The big section escape route uses supra polymer material, and rigidity is high, resistance to pressure is good, is unlikely to deform, in tunnel
When collapsing in construction, bearing capacity and environment resistant damage capability are considerably beyond general pipeline.Escape route is the double-deck channel
Protection, outside are steel construction channel, and inside is supra polymer material conduit.Enter escape route when escape, construction personnel is in the past
End opening enters, until open rearward end is left；The presence in channel shortens rescue time.
The utility model has the advantage of construction personnel is escaped from the front end of trestle to rear by this emergency measure of channel
Construction area is held or even flees from, accessible escape route is the escape route with double protection functions, greatlys improve and ensures
The escape probability of construction personnel；The rescue channel that the external world is formed by Wheelchair Accessible enters trestle front end and sues and labours, and mentions
Rescue efficiency is risen.
Detailed description of the invention
Fig. 1 is prior-art illustration.
Fig. 2 is the utility model structure diagram.
Fig. 3 is lining diagram.
Specific embodiment
The preferred embodiment of 1 to 3 pair of the utility model is described further with reference to the accompanying drawing, including passes through left and right two
Box beam 1 passes through the main bridge that crossbeam 2 is constituted, it is characterised in that；Any box beam 1 is big sectional box-type beam, and built-in big section is escaped
Raw channel 11,
Liner 111 is additionally provided in the big section escape route 11, the liner 111 is circle, and liner bottom sets row
Water hole 122, top set ventilation hole 121, once there is a small amount of water to penetrate into box beam 1, drainage hole 122 row of the water from box beam bottom
Out, it can be ensured that the drying of escape route；The ventilation hole 121 at top can ensure that escape personnel's oxygen is sufficient.
The diameter of section of the escape route 11 is not less than 800mm, and clear in channel, can accommodate at least one at
Year people quickly through.
The big section escape route 11 uses supra polymer material, and rigidity is high, resistance to pressure is good, is unlikely to deform, in tunnel
In road construction when collapsing, bearing capacity and environment resistant damage capability are considerably beyond general pipeline.Escape route is double-deck logical
Pipe protection, outside are steel construction channel, and inside is supra polymer material conduit.Enter escape route 11, construction personnel when escape
Enter from front opening, until open rearward end is left；The presence in channel 11 shortens rescue time.
