Technical Field
The utility model relates to an underground works technical field, in particular to be used for cutting road pipeline to move to change and excavation supporting conversion structure.
Background
In the existing urban road updating and reconstruction process, existing municipal pipelines are not only dense, but also are mostly arranged below a traffic main road, so that a newly-built underground structure is greatly likely to conflict with the existing municipal pipelines, and the pipeline moving and reconstruction foundation pit support and the underground structure foundation pit support interfere with each other in the construction process.
Therefore, aiming at the dense existing municipal pipelines, how to improve the pipeline moving and reforming construction efficiency of urban roads becomes a technical problem which needs to be solved urgently by technical personnel in the field.
SUMMERY OF THE UTILITY MODEL
In view of the above-mentioned defect of prior art, the utility model provides a pipeline that is used for cutting road pipeline to move changes and excavation supporting conversion structure, and the purpose of realization is to intensive existing municipal pipeline, and the pipeline that improves urban road moves changes efficiency of construction.
In order to achieve the above object, the utility model discloses a be used for cutting road pipeline to move and change and excavation supporting conversion structure, including occupying the foundation ditch that waits to change a motorway, non-motorway and the partial pavement of pipeline correspondence road.
The upper opening of the foundation pit is provided with a steel enclosure, and a plurality of support piles and a plurality of horizontally arranged supports are arranged in the foundation pit;
a pipeline supporting and hanging frame is arranged on each of the supporting piles close to one side of the sidewalk; each pipeline supporting and hanging bracket is arranged corresponding to the pipeline to be changed and temporarily erects the pipeline to be changed;
and a cutting type supporting and blocking structure is arranged in the foundation pit.
Preferably, the supporting pile is a steel plate pile, a reinforced concrete precast pile or a cast-in-situ bored pile.
Preferably, the upper ends of the support piles are provided with crown beams and steel purlins.
The utility model has the advantages that:
the utility model discloses the application is to intensive existing municipal pipeline, and the pipeline that improves the urban road moves changes the efficiency of construction.
The conception, the specific structure and the technical effects of the present invention will be further described with reference to the accompanying drawings, so as to fully understand the objects, the features and the effects of the present invention.

Detailed Description
Examples
As shown in figure 4, the conversion structure for the cut road pipeline relocation and foundation pit support comprises a motor lane 1 occupying the road corresponding to a pipeline 9 to be relocated, a non-motor lane 2 and a foundation pit 4 occupying part of a sidewalk 3.
Wherein, a steel enclosure 5 is arranged at an opening above the foundation pit 4, and a plurality of support piles 6 and a plurality of horizontally arranged supports 7 are arranged in the foundation pit 4;
a pipeline supporting and hanging bracket 8 is arranged on each of a plurality of supporting piles 6 close to one side of the sidewalk 3; each pipeline supporting and hanging bracket 8 is arranged corresponding to the pipeline 9 to be changed, and the pipeline 9 to be changed is temporarily erected;
a cutting type supporting structure 10 is arranged in the foundation pit 4.
As shown in fig. 1 to 5, the utility model discloses still provide the construction method that is used for cutting road pipeline to move and changes and excavation supporting conversion structure, occupy and wait to change a motorway 1, non-motorway 2 and some pavement 3 of pipeline 9 corresponding road as construction range, the construction step is as follows:
as shown in fig. 1, step 1, constructing a surrounding fence 5 at the outer edge of the construction range; the normal traffic operation is kept outside the enclosure 5;
in practical application, the step occupies a motorway 1, a non-motorway 2 and a part of sidewalks 3 of an undisturbed urban road to construct the enclosure 5, and the outside of the enclosure 5 keeps traffic uninterrupted.
As shown in fig. 2 to 4, step 2, constructing a support pile 6 within the range of the enclosure 5; after the supporting piles 6 reach the design strength, starting to excavate the foundation pit 4, excavating the foundation pit while erecting horizontal supports 7; and a pipeline supporting and hanging bracket 8 is erected on the inner side of the supporting pile 6 close to the sidewalk; during the process of excavating the foundation pit 4, temporarily erecting corresponding pipelines 9 to be changed on each pipeline support hanger 8 one by one;
and 5, excavating the motor way 1 on the inner side of the cut supporting structure 10, removing the supports 7, and pulling out a plurality of supporting piles 6 close to the motor way 1 in the foundation pit 4 to newly build the cut road.
As shown in fig. 4, in step 2, if the pipeline 9 to be relocated includes more than two pipelines located at different depths, the foundation pit 4 needs to be excavated to a depth corresponding to the lowest pipeline and a support 7 needs to be arranged; according to each pipeline with different depths, a pipeline supporting and hanging bracket 8 is arranged at the corresponding position of the corresponding supporting pile 6, and the pipeline with each different depth is temporarily erected.
In practical application, a foundation pit needs to be excavated according to the deepest pipeline, supports are erected according to needs, and pipeline to be changed and deep in burial depth, such as a current sewage pipe, are temporarily erected by arranging pipeline supporting and hanging frames at corresponding positions of corresponding supporting piles.
In some embodiments, the support piles 6 are steel sheet piles, reinforced concrete precast piles, or cast-in-situ bored piles.
In some embodiments, the upper ends of the plurality of support piles 6 are provided with crown beams 11 and steel purlins 12.
The foregoing has described in detail preferred embodiments of the present invention. It should be understood that numerous modifications and variations can be devised by those skilled in the art in light of the present teachings without departing from the inventive concepts. Therefore, the technical solutions that can be obtained by a person skilled in the art through logic analysis, reasoning or limited experiments based on the prior art according to the concepts of the present invention should be within the scope of protection defined by the claims.
