By arranging the plurality of the transition pipes between the pipe jacking machine and the steel pipe jacking, the pipe jacking machine rectifies a deviation, the three-dimensional hyperbolic steel pipe jacking axis formed transitional device can timely return to design axis, enable rectification of the steel pipe jacking construction to achieve a good effect, ensure accuracy of a steel pipeline jacking the axis and greatly reduce risk of a steel pipe jacking project.
Description
Technical field
The utility model relates to steel pipe jacking construction technique field, and particularly a kind of three-dimensional hyperbolic steel push pipe axis forms transition apparatus.
Background technique
Along with the development of urban construction, underground space trenchless technology more and more is being subject to people's attention, and is widely used.How install and change water supply, draining, coal gas and the communications service in city under to the prerequisite of urbicide minimum, underground Construction Technology has been proposed new demand.
Pipe jacking construction technique is a kind of trenchless technology of laying underground utility of better protection of the environment.Under the condition of its soil layer construction outside not disturbance or slight disturbance pipe, by means of the thrust of the jacking devices such as main top oil pump, tool pipe or development machine are passed soil layer along the line from active well enter received well; Meanwhile, pipeline is following closely connected successively and buries underground the construction technology of the laying under ground piping in the pipeline soil layer that connects these two wells.
At present, in the steel jacking construction, when jacking direction off-design axis, need to revise the jacking direction by push-bench correction, thus the pipeline of push-bench back can be in jack-in process the crooked purpose that reaches correction.Owing to being connected into an integral body by the steel pipe welding of jacking, be difficult for being bent, but by steel tube place's tractive of back, the correction operating effect is very poor, so steel top pipe deviation correcting operation easier is very large, usually can cause accident resulting from poor quality of projects because of direction out of control after the push-bench correction.
The model utility content
The technical problems to be solved in the utility model provides a kind of three-dimensional hyperbolic steel push pipe axis and forms transition apparatus, by between push-bench and steel push pipe, several transition tube being set, after making the push-bench correction, timely Fertilizer Test of Regression Design axis, can make the correction of steel jacking construction reach good result, guarantee the accurate of firm pipeline jacking axis, reduced widely the risk of steel pipe-jacking project.
For solving the problems of the technologies described above, a kind of three-dimensional hyperbolic steel push pipe axis forms transition apparatus, it is characterized in that: between push-bench and steel push pipe, be serially connected with a plurality of transition tube, the two ends of described transition tube are respectively equipped with bellmouth and socket, by bolted on connection, the bellmouth of one of them transition tube is inserted into the socket of another transition tube between adjacent two transition tube.
Described bellmouth and socket end are respectively arranged with the annulus of putting more energy into, and described putting more energy into is provided with vertical stiffened plate between annulus and the transition tube; The wedge type cushion block is laid in putting more energy into of described bellmouth and socket between the annulus.
Three described transition tube are set between described push-bench and steel push pipe, and described transition tube length is 3.5 meters.
Two O type watertight rubbers are set between described bellmouth and socket.
Bellmouth and putting more energy into of socket in the adjacent transition tube of two joints arrange a plurality of correction oil cylinders between the annulus.
Compared with prior art, the utility model is by arranging several transition tube between push-bench and steel push pipe, after making the push-bench correction, timely Fertilizer Test of Regression Design axis, can make the correction of steel jacking construction reach good result, guarantee the accurate of firm pipeline jacking axis, reduced widely the risk of steel pipe-jacking project.

Fig. 2 is the partial enlarged drawing that Fig. 1 indicates the circle part.
Among the figure: 1. push-bench, 2. transition tube, 3. steel push pipe, 4. bellmouth, 5. socket, the annulus of 6. putting more energy into, 7. wedge type cushion block, 8. bolt, 9. vertical stiffened plate, 10.O type watertight rubber.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1 and Figure 2, a kind of three-dimensional hyperbolic steel push pipe axis forms transition apparatus, between push-bench 1 and steel push pipe 3, be serially connected with a plurality of transition tube 2, the two ends of described transition tube 2 are respectively equipped with bellmouth 4 and socket 5, described bellmouth 4 and socket 5 ends are respectively arranged with the annulus 6 of putting more energy into, described putting more energy into is provided with vertical stiffened plate 9 between annulus 6 and the transition tube 2, increased the hoop rigidity of transition pipe joint, reduce the distortion of transition tube joint during jacking, vertical stiffened plate bears axial force for increasing transition tube rigidity is set.
The bellmouth 4 of a transition tube 2 in the adjacent described transition tube 2 of two joints is inserted into the socket 5 of another transition tube 2, wedge type cushion block 7 is laid in putting more energy into of described bellmouth 4 and socket 5 between the annulus 6, and by bolt 8 connections, improve the axial power transmission of transition tube, in case distortion and the unstability of transition tube under differential pressure; Lay wedge type cushion block 7 and can compensate on the one hand the Roughness of annulus 6 end faces of putting more energy into, increase stressed uniformity, certain deformability is arranged in the time of can making it repeatedly to carry on the other hand, can adapt to pipeline end face and when curved jacking, form the angle of inclination, and can keep the opening degree between the transition tube.
Three described transition tube 2 are set between described push-bench 1 and steel push pipe 3, and described transition tube 2 length are 3.5 meters.
Two O type watertight rubbers 10 are set between described bellmouth 4 and socket 5.The relatively movable of joint socket namely satisfied in setting like this, played again the effect of sealing.
