Description
Technical field
The utility model relates to a kind of jacking construction structures, belong to municipal works pipe culvert construction field.
Background technique
With rapid development of economy, the living standard of the people is continuously improved, and the requirement to infrastructure construction is also continuous
Promotion.Municipal administration is vertical to close piping lane, is exactly the comprehensive corridor of underground urban duct, i.e., builds a tunnel space in Urban Underground, will
Electric power, communication, the various utilities pipelines such as combustion gas, heat supply, plumbing are integrated in one, and have obtained special attention in recent years.
In order to guarantee not influence the normal operation of ground traffic, reaches a timing in piping lane cutting depth, generally use the mode of push pipe
Construction.In pipe-jacking project, the selection of pushing tow structure is extremely important, and good pushing tow organization plan can both save man power and material's drop
Low cost in turn, ensures that jacking quality and progress.In the case where duration anxiety, it usually needs to both direction in active well
Jacking, common jacking construction structure can only need to remove existing rear parados when pushing tow direction changes to a direction pushing tow, then
Again prefabricated, cause the waste of resource and duration.
Utility model content
Technical problem to be solved by the utility model is: a kind of jacking construction structure is provided, to solve in current active well
Parados after frequent installing and dismounting is prefabricated when different angle push pipe operation, there are large labor intensities, and working efficiency is low, influence to construct into
The problem of spending.
The technical solution of the utility model is: a kind of jacking construction structure, including prefabricated rear parados, and prefabricated rear parados is placed
In in round-seal reservoir, there is arc surface and burnishing surface on the prefabricated rear parados, wherein have rubber pad after arc surface, support
Lean against on the inner wall of active well, burnishing surface is opposite with arc surface, be connected with 2 jack on burnishing surface, jack it is another
One end is resisted against on push pipe to be promoted.
Parados upper surface is pre-buried there are two round steel hanging ring after prefabricated, and two round steel hanging rings are connect with hoist cable, after realization is prefabricated
The rotation and recycling of parados.
Two hanging ring centers are overlapped with prefabricated rear parados center of gravity, and are arranged symmetrically in the two sides of prefabricated rear parados center of gravity.
The arc surface and the active well borehole wall of the prefabricated rear parados are tangent.
The utility model has the beneficial effects that compared with prior art, the utility model is passed through using the prefabricated rear parados of arc
Pre-buried hanging ring, hoist cable and lifting appliance, can in active well flexible rotating position, can effectively solve prefabricated back in jacking construction
Wall is not suitable for the operation of different angle push pipe, it is prefabricated after the frequent installing and dismounting of parados, the problem of influencing construction speed.Meanwhile it is prefabricated
Parados side side is burnishing surface after arc is prefabricated, and the other side is arc surface, and burnishing surface connects jack, push pipe can be effectively ensured
Uniform force and active well are stablized.The utility model structure is simple, easy to make quick, is particularly suitable in jacking construction any
Angle single tube jacking construction uses, and can bring great convenience for jacking construction, improve the working efficiency of jacking construction.

Specific embodiment
With reference to the accompanying drawing and utility model is described further in specific embodiment:
Referring to figs. 1 to Fig. 4, according to a kind of jacking construction structure of the utility model, including it is prefabricated after parados 3, rubber pad 5,
Jack 4, hanging ring 6.There is arc surface and burnishing surface, wherein have rubber pad 5 after arc surface, for supporting after prefabricated on parados 3
On the inner wall for leaning against active well 1, burnishing surface is opposite with arc surface, for connecting jack 4, in one example, after prefabricated
3 plane of parados is in arcuation, is burnishing surface by center of circle side, and lateral surface is arc surface, the arc surface of preferably prefabricated rear parados 3 and work
1 borehole wall of well is tangent, to guarantee the reliable and stable of 2 uniform force of push pipe and active well.
The upper surface of parados 3 is connect by hoist cable 7 with lifting appliance after prefabricated.In one example, the parados 3 after prefabricated
Upper surface is pre-buried there are two round steel hanging ring 6, and two round steel hanging rings 6 preferably centered on 3 center of gravity of prefabricated rear parados, are arranged symmetrically in
Two sides, two round steel hanging rings 6 are respectively connect with a hoist cable 7, and two hoist cables 7 are connect with lifting appliance, by lifting appliance realize it is prefabricated after
The adjustment of parados 3.In other examples, it can also need to adjust the quantity and arrangement of round steel hanging ring 6 according to load-bearing and lifting.
So prefabricated rear parados 3 can rotate in active well 1, complete the propulsion of all directions pipe culvert.
When construction, prefabricated rear parados 3 is hung in active well 1 by lifting appliance first, adjustment is at suitable position
It sets, i.e., its arc surface is resisted against on the borehole wall of active well 1, burnishing surface face push pipe 2；4 one end of jack is resisted against again smooth
On face, the other end is resisted against on the push pipe 2 being installed on 1 inner wall of active well.When constructing to different angle, it is only necessary to by thousand
Jin top 4 removes, then the position of prefabricated rear parados 3 is adjusted by lifting appliance, finally installs jack 4.
It, cannot the above content is specific preferred embodiment further detailed description of the utility model is combined
Assert that the specific implementation of the utility model is only limited to these instructions.For the ordinary skill of the utility model technical field
For personnel, without departing from the concept of the premise utility, a number of simple deductions or replacements can also be made, should all regard
To belong to the protection scope of the utility model.
