The positive clear height h of abdomen at=steelframe advanced tubule to be installed, abdomen is being just at width=steelframe advanced tubule to be installed
Face clear span b, and in guiding 101 length and width cross searching of the main steel plate appropriate location trepanning on the lower side, position of opening is to be oriented to steel pipe
Angle [alpha] can be installed to design advanced tubule and pass through steelframe abdomen as standardization, and according to design requirement advanced tubule
It installs angle [alpha] and penetrates the guiding steel pipe 2；Two block baffle structural steel and irons 4 are needed with being oriented to the protruded length after main steel plate 101 welds
＞ more than steelframe depth of transverse section h 2cm to be installed, the width of 4 width of baffle arrangement steel plate≤guiding main steel plate 101；Eye-splice knot
The width of the length of structure small round steel 5=buckle structure steel plate 102.
As shown in figure 11, bored tunnel advanced tubule is used for one kind of the present invention of live profile steel frame practice of construction
For the baffle eye-splice-type guide die of setting angle control, mold is lifted by gripping structure small round steel 6, and is marking
Note advanced tubule sets buckle structure steel plate 102 is forcibly inserted into steelframe abdomen at position, until baffle arrangement steel plate 4 with
Steelframe is close to, at this point, buckle structure steel plate 102 is realized the fixation to mold, played fixation using the own resilient of steel plate bending
Mold, the function that mold is prevented to be displaced outwardly.
As shown in figure 12, bored tunnel advanced tubule is used for one kind of the present invention of live profile steel frame practice of construction
For the baffle eye-splice-type guide die of setting angle control, check die location and be oriented to whether 2 angle of steel pipe meets design
It is required that adjustment position is then gone by gripping structure when being unsatisfactory for, until meeting the requirements；After mold positioning stablity, air drill is bored
Head is inserted into together with drilling rod in the guiding steel pipe 2 of mold, and implements bore operation, and bore angle is determined with this；When a hole drilling
After, air drill drilling rod from the guiding steel pipe 2 of mold is removed, is transferred to mold by gripping structure small round steel 6, and move
To another bore position, repeat above-mentioned mold installation, drilling, extract step, until all drillings set and finish.
In the present embodiment, it is led with one kind of the present invention of live profile steel frame practice of construction for bored tunnel to be small in advance
Pipe setting angle control baffle eye-splice-type guide die for, because inside profile steel frame without structure muscle, the small-sized circle of buckle structure
Steel 5 can not be installed；More set baffle eye-splice-type guide dies and drilling construction can be processed, while is completed to multiple advanced tubules
Bore angle control.
The present invention can need to be used for what is applied after the completion of above-mentioned advanced tubule is installed according to construction and place
The baffle eye-splice-type guide die of bored tunnel advanced tubule angle control extract and is used in turn or disassembles, used
Each material still is able to recycle.
Correspondingly, the present invention also provides a kind of control method of baffle eye-splice-type guide die, the method includes with
Lower step：

Determine to be oriented to the length and width dimensions of main steel plate and buckle structure steel plate in baffle eye-splice-type guide die, be oriented to main steel plate position of opening and
Diameter is oriented to diameter of steel tube and length, buckle structure small round steel length and welding position, and baffle eye-splice-type guide die is added
Work is molded；
Step 2, on steelframe to be installed by measurement and positioning, the circumferential position that ductule is set before excess of export is marked on steelframe
It puts；
After step 3, steelframe installation are firm, guide die is lifted by gripping structure, and in marked advanced tubule
It sets and guide die buckle structure is forcibly inserted into steelframe abdomen at position, until baffle arrangement is close to steelframe, eye-splice knot
Structure steel plate utilize steel plate bending own resilient, realize the preliminary fixation to guide die, when buckle structure steel plate be inserted into until
After buckle structure small round steel is by steel frame structure muscle, with the rebound of buckle structure steel plate, buckle structure small round steel is stuck in
On the inside of steel frame structure muscle, fixed guide mold；
Whether the angle of step 4, the position for checking guide die and guiding steel pipe meets design specification requirement, when being unsatisfactory for
Position is adjusted by gripping structure, until meeting design specification requirement；
After step 5, guide die positioning stablity, air drill drill bit is inserted into together with drilling rod in the guiding steel pipe of guide die,
And implement bore operation；
Step 6, after a hole drilling, air drill drilling rod is removed, is transferred to guide die by gripping structure, and
Another bore position is moved to, repeat the above steps 3, step 4, step 5, until all drillings set and finish.
Preferably, the control method further includes：
According to on-site actual situations, more set baffle eye-splice-type guide dies and drilling construction are processed, while complete to multiple
The bore angle control of advanced tubule.
Above-described specific embodiment has carried out the purpose of the present invention, technical solution and advantageous effect further
It is described in detail, it should be understood that the foregoing is merely the specific embodiment of the present invention, is not intended to limit the present invention
