Abstract
The utility model relates to the technical field of pipeline construction, in particular to a waterstop ring for sludge-water balanced pipe jacking. The waterstop ring comprises a crack penetration part and a gear-shaped fixing structure, wherein the crack penetration part and the gear-shaped fixing structure are made from steel materials; the gear-shaped fixing structure is designed at the front end of the crack penetration part; a groove is formed in the outer wall of the middle part of the crack penetration part; a rubber sealing ring is arranged in the groove. According to the waterstop ring, sludge in a crack between the inner side of a tunnel wall and the outer side of a cement pipe and groundwater are effectively prevented from seepage, pressure balance in the crack is maintained, hole collapse is prevented, construction risks are lowered, unnecessary construction time is reduced, and the construction cost is lowered; the shortcoming that the sludge in the crack is frequently gushed to submerge an operating pit and cause hole collapse accidents under a serious condition during conventional sludge-water balanced pipe jacking construction is overcome.
Description
Technical field:
The utility model relates to a kind of pipe-line construction technical field of construction, particularly a kind of mire water equilibrium tube water stop ring.
Background technique:
Development along with pipe-line construction, pipeline is when the special locations such as driving across underneath highway, railway, building, traditional artificial soil digging jacking construction, cause is easily caved in, efficiency is low, be subject to the shortcomings such as surrounding enviroment restriction to be more and more not suitable for site operation, Slurry Balanced Pipe Jacking Construction has solved the problem that construction exists conscientiously, in non-excavation crossing construction, has obtained increasing application.Yet in Slurry Balanced Pipe Jacking Construction, between cement tube wall outside and hole wall inner side, there is gap, the phenomenon that in gap, operation hole is gushed out, flooded to mud often can occur, when serious, also can occur because mud loss causes the unbalance collapse hole accident that causes of hole internal pressure.
Model utility content:
The technical problems to be solved in the utility model is to provide a kind of mire water equilibrium tube water stop ring, this device has been realized and has effectively been prevented that inside the wall of hole and outside cement pipe, mud and the underground water in gap oozes out, keep the pressure balance in gap, prevent collapse hole, reduce construction risk, reduce the unnecessary engineering time, save construction cost.Overcome existing Slurry Balanced Pipe Jacking Construction and mud in gap often occurs gushed out, flooded operation hole, the deficiency of collapse hole accident has occurred when serious.
Technical solution adopted in the utility model is: a kind of mire water equilibrium tube water stop ring, comprises and go deep into slotted section and gear shape fixed structure; Go deep into slotted section and gear shape fixed structure and all adopt Steel material to make, going deep into slotted section Front-end Design has gear shape fixed structure, gos deep into the middle outer wall of slotted section and is designed with groove, and O-ring seal is installed in groove.
Going deep into slotted section length is 100 millimeters.
The beneficial effects of the utility model are: the utility model is owing to having adopted the mode that gear shape fixed structure is fixing and O-ring seal seals, thereby there is the function that effectively prevents that the mud in gap and underground water ooze out outside hole wall inner side and cement pipe, keep the pressure balance in gap, prevent collapse hole, reduce construction risk, reduce the unnecessary engineering time, save construction cost.
Accompanying drawing explanation:
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the left view of Fig. 1.
Embodiment:
As shown in Figure 1 and Figure 2, a kind of mire water equilibrium tube water stop ring, comprises and gos deep into slotted section 1 and gear shape fixed structure 2; Go deep into slotted section 1 and gear shape fixed structure 2 and all adopt Steel material to make, going deep into slotted section 1 Front-end Design has gear shape fixed structure 2, gos deep into the middle outer wall of slotted section 1 and is designed with groove, and O-ring seal 3 is installed in groove.Going deep into slotted section 1 length is 100 millimeters.
When the utility model is used, go deep into slotted section 1 and be inserted into sealing in the gap between wall inner side, hole and cement pipe outside, gear shape fixed structure 2 is fixed on metal sheet pile by hexagon head bolt or cement is built aboveground.
Be understandable that, above about specific descriptions of the present utility model, only for being described, the utility model is not limited to the described technological scheme of the utility model embodiment, those of ordinary skill in the art is to be understood that, still can modify or be equal to replacement the utility model, to reach identical technique effect; As long as meet, use needs, all within protection domain of the present utility model.
Claims (2)
1. a mire water equilibrium tube water stop ring, comprises and gos deep into slotted section (1) and gear shape fixed structure (2); It is characterized in that: go deep into slotted section (1) and gear shape fixed structure (2) all adopts Steel material to make, go deep into slotted section (1) Front-end Design and have gear shape fixed structure (2), in the middle of going deep into slotted section (1), outer wall is designed with groove, and O-ring seal (3) is installed in groove.
