The invention discloses a kind of construction methods of tunnel arch Fast Installation, comprising: which arch is divided at least two sections according to the arch span that tunnel needs, wherein one section is main arch section, and arch section supplemented by remaining section, wherein main arch section is that more piece arch section is spliced outside tunnel；It is outside tunnel that more Pin main arch sections are assembled good on rack, while transverse bar and mesh sheet being welded in more Pin main arch sections, so that more Pin main arch sections is formed integral structure；More Pin main arch sections are hung on the multiple arch clamping pallet of principal arm using hoisting mechanism；Arch machine drives tunnel into more Pin main arch sections, and reaches tunnel tunnel face；More Pin main arch sections are once lifted and reach installation site by arch owner cantilever crane, and manipulator station is on the ground or assembled integral by remaining arch section and more Pin main arch sections with left and right secondary arm frame.Construction technology provided by the invention can significantly improve construction efficiency, and save artificial.
Description
Technical field
The present invention relates to a kind of tunnel arch installation method, especially a kind of construction method of tunnel arch Fast Installation.
Background technique
In constructing tunnel, when country rock grade is poor, generally require to carry out arch supporting, to improve the stabilization of country rock
Property.
Existing arch machine all can only once stand a Pin arch, and arch be substantially all be divided into segment by loading machine or other
Transport vehicle transports tunnel, and short arch is then combined into long arch, and arch is taken machine by the manipulator or hanging apparatus of arch machine
On hand, then manipulator clamping arch docks tool in the sky.After the completion of arch splicing, manipulator will also hang on arch machine hanging basket
Steel mesh and weldering transverse bar.Generally speaking, the vertical arch of the existing arch machine only artificial vertical simple copy encircleed, complicated construction technique,
Efficiency is lower than artificial.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of applying for tunnel arch Fast Installation that efficiency can be made to improve
Work method.
To solve the above-mentioned problems, the technical scheme adopted by the invention is that: a kind of construction of tunnel arch Fast Installation
Method comprising following steps:
1) arch is divided at least two sections according to the arch span that tunnel needs, wherein one section is main arch section, supplemented by remaining section
Arch section, wherein main arch section is that more piece arch section is spliced outside tunnel；
2) outside tunnel that more Pin main arch sections are assembled good on rack, while transverse bar and mesh sheet are welded in more Pin main arch sections
On, so that more Pin main arch sections is formed integral structure；
3) more Pin main arch sections are hung on the multiple arch clamping pallet of main boom using hoisting mechanism；
4) arch machine drives tunnel into more Pin main arch sections, and reaches tunnel tunnel face；
5) more Pin main arch sections are once lifted and reach installation site by arch owner cantilever crane, and manipulator station is on the ground or with left and right
Secondary arm frame is assembled integral by auxiliary arch section and more Pin main arch sections.
The arch machine includes wheel undercarriage, and platform is disposed on the wheel undercarriage, has been arranged in juxtaposition on the platform
The main boom and left and right secondary arm frame, wherein main boom is equipped with the multiple arch clamping pallet, sets on the left and right secondary arm frame
There is the hoisting mechanism.
Arc size, the spacing of more Pin main arch sections as needed are assembled integral.
The arch machine stands the arch installation that one, two, three steps are carried out on a step.
The arch machine stands the arch installation that two, three steps are carried out on two steps.
Whole Pin arch is divided at least two sections by the present invention, wherein main arch section for more piece arch section is spliced outside tunnel and
The arch section of single-unit or splicing at, remaining arch section, and more Pin main arch sections splice outside tunnel it is into a single integrated structure after, it is whole
Tunnel tunnel face is transported to by arch machine, then tunnel is encircleed into dress by the collective effect of the left and right secondary arm frame of arch and main boom and is spelled
One is dressed up, the quick closure of tunnel support is realized, can at least save the construction time of half, greatly improve construction personnel
Safety and construction efficiency.

Specific embodiment
The invention will be further described with embodiment with reference to the accompanying drawing.
Arch is divided into three sections according to the arch span that tunnel needs first, including a main arch section 1 and two auxiliary arches
Frame section, the main arch section are that more piece arch section is spliced outside tunnel, and auxiliary arch section is the arch section of single-unit or splicing.
As shown in Figure 1, have rack 2 outside tunnel, arc size, the spacing that more Pin main arch sections 1 are needed according to tunnel
It is arranged in above rack 2, while transverse bar and mesh sheet being welded in more Pin main arch sections 1, more Pin main arch sections 1 is made to form integrated knot
Structure.
As shown in Fig. 2, the arch machine 3 includes chassis 5 and platform 4, left secondary cantilever crane 6, main boom are disposed on platform 4
8, right secondary arm frame 10 is equipped with hoisting mechanism 7 on left secondary cantilever crane 6, multiple arch clamping pallet 15 is housed in main boom 8.Utilize lifting
Mechanism 7 can lift more Pin main arch sections 1 on the multiple arch clamping pallet 15 for being placed into main boom 8 from rack 2.
As shown in figure 3, arch machine 3 drives tunnel 9 into more Pin main arch sections 1.
As shown in figure 4, main boom 8 is unfolded before arch machine 3 is parked in the face in tunnel 9, more Pin main arch sections 1 are lifted
To installation site.
As shown in figure 5, main boom 8, which lifts more Pin main arch sections 1, arrives installation site, it is slack later.Left secondary cantilever crane 6 is opened up
It opens, manipulator 13 thereon clamps 1 assembly of auxiliary arch 11 and more Pin main arch sections on the left side.Right secondary arm frame 10 is unfolded, thereon
The auxiliary arch 12 and more Pin main arch sections 1 on the clamping of manipulator 14 the right are assembled.
