Abstract
A kind of crack pipe fitting bracing means being used in jacking is the utility model is related to, described pipe fitting one and pipe fitting three are intact pipe fitting；Described pipe fitting two is problem pipe fitting；The inner side for the bellmouth for being provided with flange one between the bellmouth of described pipe fitting one and the socket of pipe fitting two and being welded on pipe fitting one；The inner side for the bellmouth for being provided with flange two between the bellmouth of described pipe fitting two and the socket of pipe fitting three and being welded on pipe fitting two；The inner side of described flange one and flange two is welded with steel ring cap and replaces the pressure for having crack pipe fitting to be born and top power completely by flange and steel collar, it ensure that the normal construction of push pipe operation, considerably increase the security of push pipe operation, the waste of human and material resources has greatly been retrieved, there is the advantages of high practical value.
Description
Technical field
The utility model belongs to jacking construction field, suitable for push pipe pipe internal fissure processing technology field, more particularly to one
The crack pipe fitting bracing means that kind is used in jacking.
Background technology
At present, in the technical fields such as water conservancy and hydropower pipeline water-supply engineering, ecological circulation water system pipeline engineering, usual push pipe work
The jacking operation of journey is all more than hundreds of meters, in long range jacking operation, in the event of having headed into pipe fitting large area
Huge potential safety hazard be present, easily produce booster in crack and the situation of whole road through check, the continuation jacking construction to push pipe
With disconnected pipe, cause scrapping for whole pipe-jacking project, cause the waste of human and material resources and huge economic loss.
The content of the invention
The purpose of this utility model is overcome the deficiencies in the prior art, and provide it is simple in construction, easy to use, to push pipe
Fracture unit in engineering, it is ensured that the safety of pipeline jacking and the crack pipe fitting bracing means of normal construction.
The technical solution of the utility model is：A kind of crack pipe fitting bracing means being used in jacking, including pipe fitting, flange
With steel ring cap, described pipe fitting both ends are respectively arranged with socket and bellmouth；By bellmouth with inserting between described pipe fitting and pipe fitting
Mouth docking connection, described pipe fitting include pipe fitting one, pipe fitting two, pipe fitting three；Described pipe fitting one and pipe fitting three are intact pipe
Part；Described pipe fitting two is problem pipe fitting；Be provided between the bellmouth of described pipe fitting one and the socket of pipe fitting two flange one and
It is welded on the inner side of the bellmouth of pipe fitting one；Flange two is provided between the bellmouth of described pipe fitting two and the socket of pipe fitting three and is welded
It is connected on the inner side of the bellmouth of pipe fitting two；A steel ring cap is welded between described flange one and flange two；Described steel ring cap
Tightly it is bonded positioned at the inside of pipe fitting two and with the inwall of pipe fitting two.
The thickness of described steel ring cap is not less than 200mm.
Described flange one, flange two and steel collar can be cut.
Beneficial effect is caused by this programme：Generally, the utility model has simple in construction easy to use, by flange
Replace pressure and top power that crack pipe fitting is born completely with steel collar, and flange and steel collar can be cut, it is convenient
Welded and installed in pipe is transported into, ensure that the normal construction of push pipe operation, the security of push pipe operation is considerably increased, greatly draws
The waste of human and material resources has been returned, there is the advantages of high practical value.

Embodiment：
The technical solution of the utility model is described further below in conjunction with the accompanying drawings.
As shown in Figure 1, 2：A kind of crack pipe fitting bracing means being used in jacking, including pipe fitting, flange and steel ring cap 1,
Described pipe fitting both ends are respectively arranged with socket 2 and bellmouth 3；Docked between described pipe fitting and pipe fitting by bellmouth 3 with socket 2
Connection, described pipe fitting include pipe fitting 1, pipe fitting 25, pipe fitting 36；Described pipe fitting 1 and pipe fitting 36 are intact pipe
Part；Described pipe fitting 25 is problem pipe fitting；Flange one is provided between the bellmouth of described pipe fitting 1 and the socket of pipe fitting 25
7 and it is welded on the inner side of the bellmouth 3 of pipe fitting 1；Method is provided between the bellmouth of described pipe fitting 25 and the socket of pipe fitting 36
Orchid 28 and is welded on the inner side of the bellmouth 3 of pipe fitting 25；A steel ring cap is welded between described flange 1 and flange 28
1；Described steel ring cap 1 is located at the inside of pipe fitting 25 and is tightly bonded with the inwall of pipe fitting 25.
The thickness of described steel ring cap 1 is not less than 200mm.
Described flange 1, flange 28 and steel collar 1 can be cut.
The utility model Specific construction mode：The concrete for replacing pipe fitting bell and spigot both sides is first rejected, respectively by two Dow process
Blue side is spliced in the both sides for having rejected pipeline opening, and with the bell and spigot full weld of former pipe fitting；The opposite side of flange respectively with method
Steel collar welding among blue（Full weld）, steel collar, which plays, connects two flanges effects, two flanges and steel collar is turned into one
Body substitutes the pipe fitting for having crackle being removed completely.
