Make two platforms in left and right
（1）Make the first landing slab
With 50 × 50 × 4mm of model square tube（Length × width x thickness）, rectangular frame, square are made by welding manner
Shape frame size is 2500 × 1500mm（Length × wide, a length of tunnel axis direction）；
With two 50 × 37 × 4.5mm of model channel-section steel（Waist height × leg is wide × and waist is thick）, it is parallel by welding manner
It is fixed on the reinforcement 6 as U-shaped on rectangular frame.In order to connect diagonal brace 7, the high face of channel-section steel waist（It is provided with the one of connecting plate 5
Side）Welded towards at the top of rectangular frame, U-shaped mouth is towards rectangular frame bottom；
2500 × 1500 × 3mm（Length × width x thickness）Checkered steel plate be welded at the top of rectangular frame.
(2) the second landing slab is made
The sidepiece that second landing slab 3 is connected with development machine large arm uses 50 × 100 × 4mm of model square tube（It is long × wide
× thick）, other parts are identical with the first landing slab 2；
Second landing slab 3 uses the square tube that width is 100mm, it is therefore an objective to when the landing slab of left and right two is packed up, two platforms
Plate level can be overlapped together one on the other.First landing slab 2 is first packed up, and position is packed up under after the platform of the second landing slab 3,
Position is upper.
（3）Determine two landing slab installation sites
Front end of the front end of first landing slab 2 and the second landing slab 3 with development machine large arm 1 is concordant, the platform of left and right two
Plate correspondence is installed in the left and right sides of development machine large arm 1 (left and right is determined with development machine direction of advance).
（4）Landing slab and development machine large arm connection method
Each landing slab is connected with two cylindrical hinges and development machine large arm 1.Each hinge has two pipes and one is inserted
Pin bank is into 38 × 31 × 3.5mm of pipe model（External diameter × internal diameter × wall thickness）, latch is 28mm round steel.Two pipe difference
It is welded in large arm and platform, connects two pipes with latch, then latch is pinned with split pin.First landing slab 2 and the second platform
Plate 3 can be rotated by hinge around large arm, and when the first landing slab 2 and the second landing slab 3 are packed up, the first landing slab
2 and second landing slab 3 top down, bottom-up, the top of the first landing slab 2 and the top contact of development machine large arm 1, the
The bottom of one landing slab 2 is in contact with the top of the second landing slab 3.
（5）Diagonal brace is made with being connected
Using length diagonal brace 7 is made for 1600mm, φ 40mm round steel.The wide place of leg in round steel one end and channel-section steel termination
（That is biside plate 4）16mm circular hole is bored respectively, and round steel and channel-section steel are linked together with φ 12mm latches, then is pinned with split pin
Latch.
（6）Determine diagonal brace position of the fulcrum with making diagonal brace fulcrum
The fulcrum of diagonal brace 7 is determined along corresponding reinforcement 6 in the left and right sides bottom of development machine large arm 1（That is base）Position
Put, each landing slab is in diagonal brace link position 10（That is one end bottom of the side plate 4 away from the development machine large arm 1）Place is connected with two
Diagonal brace 7, each diagonal brace 7 is supported on a base, each on the side of left and right two of development machine large arm 1 to make two diagonal braces respectively
Fulcrum, it is 100mm, 50 × 50 × 4mm of model channel-section steel that a length, which is respectively welded, in each position of the fulcrum, and channel-section steel has two kinds
A kind of arrangement, arrangement is that channel-section steel is placed vertically, and its opening direction deviates from the left and right sides of development machine large arm 1, and
Welded and blocked with iron block in the lower end position of opening, during support, diagonal brace 7 is supported on the top of iron block, and another arrangement is
Closure upwards, and is welded in the top of opening by channel-section steel horizontal positioned, its opening direction with iron block, and iron block is located on channel-section steel away from pick
Enter one end of machine large arm 1, during support, diagonal brace 7 is supported in the opening of channel-section steel and positioned between development machine large arm 1 and iron block.
（7）Two platforms are opened with packing up
Before grid erection, two landing slabs in left and right are opened manually, and support diagonal brace, workman can erect-position operation.Two
When landing slab is opened, the width of development machine large arm 1 is added, overall width is 4800mm, fully meets construction requirement.It is complete in spray anchor process
Cheng Hou, then two landing slabs in left and right are manually packed up, level is overlapped together.Because a landing slab width is 1500mm, driving
The width of machine large arm 1 is 1800mm, so after two landing slabs are packed up, being not take up the horizontal and vertical space of development machine, not influenceing machine
The normal tunneling construction of tool.
In summary, by means of above-mentioned technical proposal of the present utility model, constructing tunnel saves many times, accelerates
Construction speed, improves operating efficiency, and the operation of workman's erect-position is also very safe.Compare and set up interim portal frame and both saved a lot
Time, security is improved again；Compare using steel construction bogie frame, save the plenty of time.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
Within the spirit and principle of utility model, any modification, equivalent substitution and improvements made etc. should be included in the utility model
Protection domain within.
