Abstract
The utility model relates to a supporting construction technical field just discloses a foundation ditch supporting construction of existing pipeline, including fender pile, pipeline, guan liang and steel grating, the fender pile is provided with a plurality ofly, steel grating is fixed with two relative one sides of fender pile that are located the middle part, the bottom of guan liang is fixed with the top of fender pile, the pipeline is located the below of steel grating. The foundation pit supporting structure with the existing pipeline can be used for solving the problems that due to the existence of the existing pipeline, pipeline position supporting cast-in-place piles cannot be constructed, the interval between the pipeline position supporting piles is too large, and soil between piles is easy to collapse.
Description
Technical Field
The utility model relates to a supporting construction technical field specifically is an underground structure of existing pipeline.
Background
With the vigorous development of urban construction, more and more deep foundation pits appear, and the row pile support is widely applied to the deep foundation pits. In a site where pipelines exist in a foundation pit, under the condition that the pipelines need to be protected due to the fact that the pipelines are not moved in time and are not close to each other, the cast-in-place piles are supported at the pipeline positions by row piles, and particularly for the pipelines with large diameters, the net spacing between the support piles at the pipeline positions needs to be large, otherwise, the pipeline construction is influenced. Due to the operation of soil pressure, the larger clear space between the support piles makes the soil between the piles collapse easily, which has great influence on the surrounding environment and needs to take safe protection measures for the soil between the piles. Through set up steel grating between the stake, spout concrete operation on steel grating surface, can effectively protect soil between the stake, prevent that soil between the stake from collapsing.
At present, due to the existence of existing pipelines between supporting piles, the pipeline position supporting cast-in-place piles cannot be constructed, so that the intervals between the supporting piles at the pipeline position are too large, pipelines which cannot be changed can not be moved, and the net intervals of the piles are too large.
SUMMERY OF THE UTILITY MODEL
Technical problem to be solved
Not enough to prior art, the utility model provides a foundation ditch supporting construction of existing pipeline possesses and sets up a series of steel grating and spouts the concrete between a fender pile to the realization has solved the problem that proposes among the above-mentioned background art to the advantage of the protection of soil between the stake.
(II) technical scheme
The utility model provides a following technical scheme: the utility model provides a foundation ditch supporting construction of existing pipeline, includes fender pile, pipeline, guan liang and steel grating, the fender pile is provided with a plurality ofly, steel grating is fixed with two relative one sides of fender pile that are located the middle part, the bottom of guan liang is fixed with the top of fender pile, the pipeline is located the below of steel grating.
Further, the bottom of steel grating is equipped with the cavity, the pipeline is located the inside of cavity.
Furthermore, two sides of the steel grating are welded with main ribs of the fender post.
Further, the vertical interval of steel grating is 50cm.
Furthermore, the steel grating installation is carried out layer by layer along with the excavation of the foundation pit, and the concrete spraying operation can be carried out after one layer of steel grating is installed.
Compared with the prior art, the utility model provides a foundation ditch supporting construction of existing pipeline possesses following beneficial effect:
the foundation pit supporting structure with the existing pipeline can be used for solving the problems that due to the existence of the existing pipeline, pipeline position supporting cast-in-place piles cannot be constructed, the interval between the pipeline position supporting piles is too large, and soil between piles is easy to collapse.

FIG. 2 is a vertical view of the protection between the fender posts of the utility model;
fig. 3 is a top view of the utility model of protecting between fender piles.
Wherein: 1. a fender pile; 2. a pipeline; 3. a crown beam; 4. a steel grid.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
The utility model provides a foundation ditch supporting construction of existing pipeline, includes fender pile 1, pipeline 2, guan liang 3 and steel grating 4, and fender pile 1 is provided with a plurality ofly, and steel grating 4 is fixed with two fender piles 1 relative one side that are located the middle part, and the bottom of guan liang 3 is fixed with fender pile 1's top, and pipeline 2 is located the below of steel grating 4.
As shown in figure 1, local pipelines such as sewage pipes cannot be moved and changed, in-situ protection is needed, bored piles at the pipeline positions cannot be constructed, and support piles are arranged on two sides of the pipelines.
As shown in fig. 2, the supporting piles are constructed by adopting a grid and concrete spraying. The steel grating is arranged between the support piles, the vertical interval of the grating is 500mm, the width is generally not more than 5m, and the top of the grating is flush with the bottom of the crown beam.
As shown in fig. 3, the steel grating and the pile main reinforcement adopt double-sided welding seams.
This foundation ditch supporting construction of existing pipeline can be used for solving because the existence of existing pipeline, and pipeline position is strutted bored concrete pile and is unable to be under construction, leads to pipeline position to prop between the pile interval too big, and the problem that the soil collapses easily between the pile, through set up a series of steel grating and spray concrete between the fender pile to realize the protection to soil between the pile, guarantee foundation ditch safety, improve the stability of foundation ditch, can extensively apply to multiple job site.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
