Description
Technical field
This utility model relates to the device used in a kind of pipe jacking construction technique, particularly in push-bench construction rear conduct
A kind of steel bushing of boosting facility.
Background technology
Normal jacking construction is for put into push-bench at active well, and puts into sectional pipe of concrete at active well
And make push-bench advance to received well direction, then at received well, push-bench is regained.But in case of exceptional circumstances, push-bench and
It is just the most active in underground that push-bench pipe of concrete below does not arrives received well, and can not set up in the position that push-bench stops
During received well, need a kind of effective manner to be regained by push-bench, and the engineering being not fully complete is completed.
Summary of the invention
This utility model provides a kind of working steel bushing of push-bench, and the jack after push-bench can be coordinated easily will
Push-bench ejects, and the supporting periphery ground that can consolidate.
In order to solve above-mentioned technical problem, this utility model one receives the working steel bushing of push-bench, described steel bushing
Cylinder includes columnar sidewall, and described sidewall is welded with near the end of jack and is perpendicular to sidewall inwardly projecting annular
Counter-force seat ring flange, between described counter-force seat ring flange and sidewall inwall, weld multiple counter-force seat ring flange that is supported on, and
The stiffener of the right angled triangle between sidewall.
Sidewall described in the utility model is that Plate Welding thick for polylith 20mm is constituted.
This utility model described counter-force seat ring flange be double welded joint full weld structure after the splicing of prefabricated curved plate
Become.
Double welded joint full weld is used between stiffener described in the utility model and counter-force seat ring flange and sidewall inwall.
Annular spacing 25cm between stiffener described in the utility model.
Sidewall described in the utility model is made up of 9 block plate welding.
Counter-force seat ring flange described in the utility model is spliced to form by 9 pieces of curved plates.
Composition sidewall described in the utility model, the steel plate of counter-force seat ring flange are be prefabricated in the factory.
Compared with prior art, this utility model one reception working steel bushing of push-bench includes columnar sidewall
And the counter-force seat ring flange of inwardly projecting annular, counter-force seat ring flange can provide new to the jack on push-bench
Start of a run, and along with the spreading successively of steel bushing, serve the effect of steel pipe supporting peripheral rock, counter-force seat ring flange is again
As the ribbed stiffener of steel bushing, enhance the steel bushing support stiffness to managing outer country rock.
Accompanying drawing explanation
Fig. 1 is that steel bushing coordinates the structural representation at tunnel in-cavity construction with push-bench.
Fig. 2 is the sectional structure schematic diagram that steel bushing coordinates jack construction.
Fig. 3 is the perspective view of steel bushing.
Detailed description of the invention
Below in conjunction with the accompanying drawings detailed description of the invention of the present utility model is described in further detail.
As shown in Fig. 13, this utility model one receives the working steel bushing of push-bench, in constructing at push-bench 1
Specific time the device that uses, push-bench 1 is by prior art, for using jack 2 to coordinate pipe of concrete jacking in the soil body
Mode, normal form of construction work be active well increase pipe of concrete advance, but steel bushing described in the utility model 3 is used
Pipe of concrete can not in the soil body situation of movement, need on the basis of original pipe of concrete jacking push-bench 1, therefore design
Steel bushing 3 structure is for supporting peripheral rock between push-bench 1 tail end and former pipe of concrete and as the new row of push-bench 1
Cheng Qidian.It is provided with jack 2, along with the advance of push-bench 1, after jack 2 is retracted, the assembly of sections at push-bench 1 head-tail
Welding steel bushing 3 carries out push pipe operation.
Concrete, described steel bushing 3 includes the cylinder side wall 31 surrounded by the steel plate thick not less than 20mm, at sidewall 31
The counter-force seat ring flange 32 of sidewall 31 inwardly projecting annular it is perpendicular to, at counter-force seat near the welding of the end of jack 2
Multiple right angled triangle being supported between counter-force seat ring flange 32 and sidewall 31 is welded between ring flange 32 and sidewall 31 inwall
Stiffener 33.Described steel bushing 3 is the structure welded at the construction field (site), takes the part of steel bushing 3 to pipe of concrete
And place's welding between push-bench, the most complete steel bushing 3 can not be by the passage of pipe of concrete.
The when of construction at the scene, when, after jack 2 jacking 50cm stroke, jack 2 is retracted, at the one before steel bushing 3 or
Near one end of jack 2, welding forms new steel bushing 3 to pipe of concrete, and the mode of welding is first to weld sidewall 31, sidewall 31
Being spliced to form by polylith steel plate, preferably sidewall 31 is that nine block plates are spliced, then at sidewall 31 near the end of jack 2
Portion welding counter-force seat ring flange 32, counter-force seat ring flange 32 is also spliced to form for plurality of steel plates, preferably ring flange be nine pieces prefabricated
After good curved plate splicing, double welded joint full weld is constituted, then at counter-force seat ring flange 32 and sidewall 31 inwall vertical angle
The stiffener 33 of welding polylith right angled triangle reinforces the counter-force seat ring flange 32 of annular, the right angle portions of stiffener 33 just position
At counter-force seat ring flange 32 and sidewall 31 inwall vertical angle, circumferential distance 25cm between stiffener 33 and stiffener 33, weldering
Start jack 2 after connecting, make jack 2 withstand on the counter-force seat ring flange 32 welded and promote push-bench 1 before tunnel 3
Enter.So circulation is until by 1 whole jacking of push-bench to tunnel.Between counter-force seat ring flange 32 and sidewall 31, stiffener
Double welded joint full weld is all used between 33 and counter-force seat ring flange 32 and sidewall 31.
Along with the spreading successively of steel bushing 3, serving the effect of steel pipe supporting peripheral rock, counter-force seat ring flange 32 is again
As the ribbed stiffener of steel bushing 3, strengthen the steel bushing 3 support stiffness to managing outer country rock.
