Abstract
The utility model relates to a kind of tunnel bracing members installation auxiliary device, it include: bearing support, bearing support middle part be equipped with jack, be connected with a steel pipe above jack, a jacking connected on steel pipe, jacking connects vault bracing members.The construction personnel that the utility model efficiently solves tunnel support work surface is more, reduce the time of personnel's operation under unstable surrounding rock, provide the tunnel bracing members installation auxiliary device that a kind of safety coefficient is high, speed of application is fast, the number of turnover is more, structure is simple, is easily installed, it ensures production safety, produces great social and economic benefit.
Description
Technical field
The utility model belongs to the technical field of construction such as water conservancy and hydropower, highway, railway, municipal administration, and in particular to a kind of tunnel
Bracing members installation auxiliary device.
Background technique
In the engineering constructions such as water conservancy and hydropower, highway, railway, municipal administration, to ensure Wall Rock of Tunnel stabilization and construction safety,
During tunnel support, preliminary bracing generally uses bracing members to carry out supporting construction after excavating for IV, V class surrounding rock.By right
It excavates region and carries out bracing members reinforcing, can carry immediately, to ensure the stabilization of tunnel excavation country rock.In previous underground chamber work
In the construction of journey excavation supporting, when especially constructing to the bracing members of preliminary bracing, mostly based on manually installed, work surface installation
Personnel are more.For the location of country rock difference, tend to produce because surrounding rock stability is poor, safety accident caused by supporting not in time etc.
Raw biggish economic loss is unfavorable for the engineering constructions such as current water conservancy and hydropower, highway, railway, municipal administration construction and to safety, economy
The demand of benefit.
Utility model content
The purpose of this utility model is the construction personnel in order to control supporting work surface, reduces personnel under unstable surrounding rock
The time of operation provides the tunnel that a kind of safety coefficient is high, speed of application is fast, the number of turnover is more, structure is simple, is easily installed
Bracing members installation auxiliary device, it is ensured that production safety.
A kind of the technical solution of the utility model are as follows: tunnel bracing members installation auxiliary device, comprising: bearing support, bearing support
Middle part be equipped with jack, the steel pipe of a different-diameter is connected with above jack, a jacking is connected on steel pipe, jacking connects vault
Bracing members.
The bearing support be it is tower-shaped, be made of fashioned iron, lacing wire and steel plate up and down two ladder-shaped frames.
The vault bracing members are arc.
The jacking is T shape, and here is joint steel pipe, and the above is connection vault bracing members rectangle frame slot.
The good effect of the utility model:
1, it realizes and realizes temporary support protection in the arch of non-supporting, reduce the dead time of personnel, effectively improve
The safety coefficient of bracing members arch installation personnel, it is ensured that construction production safety.
2, using the device, the speed that construction personnel installs arch is accelerated, the construction time is shortened.
3, lightweight construction, assembly and disassembly are flexible and convenient, and the number of turnover is more, produce greatly society and economic effect
Benefit.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment

Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, with reference to embodiments, to this
Utility model is further elaborated.It should be appreciated that specific embodiment described herein is only used to explain that this is practical
It is novel, it is not used to limit the utility model.
As shown in Figure 1, the tunnel bracing members installation auxiliary device of the utility model is by bearing support, bearing support be it is tower-shaped, by
Fashioned iron 1, lacing wire 2 and steel plate 4 constitute two ladder-shaped frames up and down.The middle part steel plate 4 of bearing support is equipped with jack 3, such as Fig. 4, Fig. 5
It is shown.It is connected with the steel pipe 5 of a different-diameter above jack, a jacking 7 is connected on steel pipe, the jacking 7 is T shape, under
Face is joint steel pipe, and the above is connection vault bracing members rectangle frame slot, as shown in Figure 2 and Figure 3.Jacking connects vault bracing members 6,
For fixing arch bracing members, the vault bracing members are arc.
Specific production method: fashioned iron, lacing wire, steel plate, different model steel pipe, vault bracing members and top are carried out according to design drawing
Jack is purchased in the blanking and assembling of support.After processing is completed, progress is assembled for tunnel bracing members auxiliary device main structure, then with
Jack combination debugging.After the completion of tunnel excavation is got rid of the danger, the hole slag charge within the scope of device is cleaned out first, then carries out device peace
Arch steel arch-shelf top is carried out the installation of arch reinforced mesh, reinforced mesh at scar 5cm height using jack by dress
By arch steel arch-shelf top to scar after being installed, spray concrete is then carried out.After the completion of the preliminary bracing of arch, it is connected with top
Fashioned iron is allowed to form entirety, then hangs reinforced mesh in time and is welded to connect muscle, so that front and back steel arch-shelf is formed entirety, finally tear open
Except auxiliary device, it is transferred to the use of subsequent cycle steel shotcrete support.
