Description
Technical field
The utility model relates to constructing tunnel field, the steelframe supporting of specially a kind of tunnel adjustable up-down spacing is installed
Support frame.
Background technique
In actual tunnel work progress, such as Tunnel Passing cyclopentadienyl river in Shangdong Province, Mao County active breaking belt, belong to serious large deformation stratum
Rock matter is carbonaceous phyllite, is mingled with quartzite, easy-weathering, and structural belt iso-stress is easily concentrated, and large deformation paragraph is pre- using three steps
The engineering method of Core Soil is stayed to excavate.When Specific construction, Mao County serious deformation is according to advance geologic prediction achievement, according to design parameter
Standard construction: preliminary bracing is using the double-deck supporting；Two layers of steelframe is all made of loopful HW175 profile steel frame, spacing 60cm, steelframe
Tolerance 10cm, 2 ° of perpendicularity deviation, two layers of supporting applies by several times.Excavation method uses three step provided core soil methods, by
Construction space is greatly reduced in Core Soil, construction space is unable to satisfy the construction requirement of steelframe fitting machine, and steelframe supporting is taken
Traditional artificial supporting.The time-consuming effort of artificial Bracing Process, and steelframe spacing deviation, the control of perpendicularity deviation is poor, thus
The adjustable spacing support frame of liftable is had developed, these problems can be well solved.
Summary of the invention
During practice of construction, HW175 profile steel frame weight 40.1kg/m, every section arch weight 120.3kg appear on the stage
Rank supporting steelframe gross weight 601.5kg, steel arch-shelf straightening during artificial supporting, the operation such as adjusting spacing is time-consuming and laborious, in conjunction with
Actual conditions the utility model provides a kind of light support frame of adjustable spacing of liftable.
The utility model adopts the following technical scheme that realization:
The utility model adopts the following technical scheme that realization:
A kind of steelframe supporting installation support frame of tunnel adjustable up-down spacing, including bearing tray, the bearing tray
On be fixed with adjusting sleeve, the adjusting sleeve upper end, which is equipped with, adjusts location tray, and the adjusting sleeve interpolation enters height adjustment
Screw rod, has screwed height adjustment nut on the height adjusting screw rod, and the height adjustment nut support is in adjusting location tray
On, the height adjustment nut is symmetrically welded with rotational handle；The adjusting screw rod upper end, which is fixed with, is used to support fashioned iron
Card slot support base, card slot support base side is horizontally disposed spacing kelly, and the spacing kelly is equipped with for limiting phase
The upright bar of adjacent fashioned iron spacing.
At the scene in construction, which goes up and down principle referring to concrete tank hopper, is constantly trying to improve, in conjunction with existing
Field practical operation improves.By rotational handle rotation height adjusting nut, so that height adjusting screw rod is stretched out or is withdrawn
In adjusting sleeve, after adjustment height is suitable, height adjustment nut is by height adjustment nut support in the branch for adjusting sleeve top
It supports in location tray.The type steel support of support of tunnel steelframe on the card slot support base of the support frame, between adjacent steelframe away from
It is determined from by the spacing kelly on the support frame.The support frame be mainly used in steel arch-shelf unit it is combined and spliced during face
When the support and alignment of steelframe connecting plate, lift adjustment when tightening bolt, pass through spacing kelly and guarantee arch spacing, level, generation
For manual support.From the point of view of actual use situation, construction safety is not only met, ensure that construction quality, and improve
Execution conditions promote construction speed.
The main component of support frame forms: bearing tray adjusts sleeve, adjusts location tray, band reinforcing stem nut, support
Frame head (band card slot support base).
During Specific construction, HW175 profile steel frame, spacing 60cm, fashioned iron width 17.5cm.Support frame uses diameter
Φ 40mm seamless steel pipe above wears the threaded height adjustment body of rod of diameter of phi 32mm as telescopic adjustment sleeve, is adjusted by height
Nut is saved to adjust the protruded length of telescopic rod, to reach lift action.Support frame head (card slot support base) width is
18.0cm(fashioned iron width 17.5cm), limitation steel arch-shelf or so offset.Between the upright bar and card slot support base right side wall of spacing kelly
Away from 60cm, the work 18 of the position 1m connects steel on connecting plate of getting out of a predicament or an embarrassing situation in cooperation, guarantees steelframe separation criteria 60cm.Bearing tray makes
Obtain entire force structure supporting & stablizing, it is ensured that construction safety.Telescopic adjustment sleeve and telescopic rod all use hollow material, significantly
Ground mitigates self weight, improves practicability.The connection type of support frame is welding, and all welding positions are all fully welded, and weld seam is full,
Meet structural support force request.
Support frame can meet the steelframe support work of different construction requirements according to actual construction parameter.Support frame can be used for
Three step remaining core soil in advance excavate top bar position, provide support of stopping over by Core Soil, can support for a long time, adjust arch ten
It is convenient to divide, and reinforces muscle by rotational handle and adjusts a little strength of lifting cost.
Since tunnel working geology situation is complicated and changeable, different geological conditions corresponds to different construction parameters, to meet
Different construction parameters has high requirement for the spacing and verticality of steelframe in steelframe supporting, to meet steelframe standard
Construction, support frame head (card slot support base) position and spacing kelly can use movable nut card slot instead and replace.
For making material, support frame former material is easily available, extremely facilitates processing and fabricating, and facilitate one man operation, behaviour
Make simple；For construction quality, supporting frame refers to the standard size of construction reference parameter processing, greatly ensure that steel
Frame supporting quality ensure that the construction quality of Large Deformation Support system；For construction safety, support frame force structure has greatly
Ground reliability replaces force structure as manual support, can replace three worker's supports of support, can greatly save people
Power；The support high reliablity of support frame reduces construction risk caused by exhausting because of people's fatigue power, ensure that manpower in artificial support
The safety of construction；
Artificial supporting completely, the every cycle operation duration 4.5h of stand, when using support frame operation are counted according to usually joining a regular shift or class
It is about 3.5h ~ 4h, shortens operation time, promotes construction speed.
Support frame, there are higher cost performance, not only meets construction safety in terms of construction, ensure that construction quality, and
And execution conditions are improved, promote construction speed.It has also been found that existing defects in work progress, if do not can be carried out longitudinal bracing tune
Section, support frame head are not able to satisfy Arbitrary Rotation etc., and one is scheduled in subsequent construction and is improved.In following construction,
Mechanized construction is irresistible trend, but for three step remaining core soil in advance excavation method of soft rock large deformation, it is this
The support frame of type has very big practicability in terms of construction, uses well in steelframe supporting, builds out high standard, high-quality
The fine work Tunnel Engineering of amount.
The utility model is designed reasonably has good practical application and promotional value.
