Abstract
The utility model discloses a transition pipe for the deviation correction of a steel pipe jacking. A plurality of transition pipes are connected between a tool pipe and the steel pipe jacking in series; and adjacent transition pipes are connected by adjusting bolts, wherein a recessed step is arranged at the end part of one transition pipe, and a clamping table clamped with the step is extended from the end part of the other transition pipe. By adopting the transition pipe, the design axis can be timely regressed, so as to achieve good effect for the deviation correction of steel pipe jacking construction, ensure accuracy for jacking axes of steel pipelines, and greatly reduce the risk of the steel pipe jacking project.
Description
Technical field
The utility model relates to steel pipe pipe jacking construction technique field, specifically belongs to steel push pipe correction transition tube.
Background technique
In the steel pipe jacking construction, when jacking deviation in driction design axis, need revise the jacking direction by the tool pipe correction, thereby the pipeline of tool pipe back can be in jack-in process the crooked purpose that reaches correction.As a whole owing to being welded into by the steel pipe of jacking, be difficult for being bent, but by steel tube place's tractive of back, the correction operating effect is very poor after the tool pipe correction, so steel push pipe correction operation easier is very big, usually can cause accident resulting from poor quality of projects because of direction out of control.
The model utility content
The purpose of this utility model provides a kind of steel push pipe correction transition tube, by the mobilizable transition tube coupling of number joint is set between tool pipe and steel pipe, after making the tool pipe correction, timely Fertilizer Test of Regression Design axis, can make the correction of steel pipe jacking construction reach good result, guarantee the accurate of steel pipeline jacking axis, reduced the risk of steel pipe-jacking project widely.
The technical solution of the utility model is as follows:
Steel push pipe correction transition tube, between tool pipe and steel push pipe, be serially connected with a plurality of transition tube, by regulating Bolt Connection, the end of one of them transition tube is provided with the step of depression between the adjacent transition tube, and the end of another transition tube is extended with the Ka Tai that fastens with step.
Be equipped with rubber seal between described Ka Tai and the step.
In the jack-in process of the present utility model, bolt unclamps certain interval, allows can swing relatively within the specific limits between tube coupling.The gap of bolt is regulated as required at any time, and both having allowed can be movable between tube coupling, guarantees that again tube coupling can not throw off suddenly.
The utility model is by being provided with the mobilizable transition tube coupling of number joint between tool pipe and steel pipe, after making the tool pipe correction, timely Fertilizer Test of Regression Design axis, can make the correction of steel pipe jacking construction reach good result, guarantee the accurate of steel pipeline jacking axis, reduced the risk of steel pipe-jacking project widely.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a connection diagram between the transition tube of the present utility model.
Embodiment
Referring to accompanying drawing, steel push pipe correction transition tube, between tool pipe 1 and steel push pipe 2, be serially connected with three transition tube 3, connect by regulating bolt 4 between the adjacent transition tube, regulating bolt thread is connected in the position limit socket 5 on the transition tube inwall, the end of one of them transition tube is provided with the step 6 of depression, and the end of another transition tube is extended with the card platform 7 that fastens with step, is equipped with rubber seal 8 between Ka Tai and the step.
Claims (2)
1. the steel push pipe is rectified a deviation and is used transition tube, between tool pipe and steel push pipe, be serially connected with a plurality of transition tube, it is characterized in that: pass through to regulate Bolt Connection between the adjacent transition tube, the end of one of them transition tube is provided with the step of depression, and the end of another transition tube is extended with the Ka Tai that fastens with step.
2. transition tube is used in described steel push pipe correction according to claim 1, it is characterized in that: be equipped with rubber seal between described Ka Tai and the step.
