Description
Technical field
The utility model relates to underground pipe gallery structures.
Background technique
With the construction process and population of China's modern city and the increase of mining inetesity, need of the city to municipal pipeline
Ask higher and higher, quantity is increasing, and traditional municipal pipeline laying method can no longer meet demand.By external many years
Practical experience proves, the construction of Urban Underground pipe gallery can solve repeatedly that excavated pavement, aerial gauze be intensive, pipeline accident frequency
The problems such as hair, is conducive to ensure urban safety, improves city function, beautifying city landscape, promotes city intensive efficient and transition
Development is conducive to improve urban carrying capacity and urbanization quality, is conducive to increase public product effective investment, draw
Dynamic social capital.
Underground pipe gallery is constructed based on reinforced concrete structure, but when using cast-in-place concrete construction at present
Operating speed is slow, big for the traffic impact of major trunk roads, brings huge inconvenience to resident living, in addition, concrete structure is anti-
Uneven settlement of foundation, impermeability are all poor, when there is biggish differential settlement, it may appear that cracking and drainage.When
When concrete structure uses prefabricated construction, although can accelerate construction progress, guarantee construction quality, its jointing is always
It is a problem, when using rigid connection, is easy to appear and fractures when there is larger differential settlement；When using flexible connection
When, drainage or significant at general jointing, using efficient sealed flexible joint, then connector required precision is high, processing
It is sufficiently complex.
Due to the presence of these problems, utilization of the corrugated steel tube pipe gallery in China gradually increases.Corrugated steel tube is comprehensive
Piping lane can not only avoid wet construction, accelerate construction progress, and due to the presence of pipe shaft ripple, work is cooperateed with surrounding soil
With keeping its stress more reasonable, anti-uneven settlement of foundation performance is also more preferable.On Anticorrosion, external correlative study shows
For corrugated steel after specially treated, antiseptic property is good.However corrugated steel tube is relatively soft, is easy to produce when span is excessive
Unstable phenomenon, and section form is relatively fixed, and generally circular in cross section or oval, circular cross-section is empty relative to rectangular section
Between utilization rate it is poor, furthermore corrugated steel tube is the phenomenon that bolt hole position and section intersection are still easy to appear leakage.
Utility model content
The utility model will solve the anti-uneven settlement of foundation of current concrete structure, impervious poor, prefabricated piping lane
The problem of connector easy fracture, leak, corrugated steel piping lane stable structure Lack of support, and the wave for being used for underground pipe gallery is provided
Line steel outer lining concrete structure.
The utility model for underground pipe gallery corrugated steel outer lining concrete structure include outer lining reinforced concrete pedosphere,
Encircle body corrugated steel and bottom plate, wherein outer lining coagulation pedosphere, which is coated in the outer plate surface of arch body corrugated steel, forms arch body, the bottom of at
Laterally the left and right sides is embedded with reinforcing bar to plate respectively, encircles and is provided with slip casting sleeve in the arch springing of body, the reinforcing bar on bottom plate is inserted into arch springing
In slip casting sleeve in, be perfused with concrete in slip casting sleeve, the periphery that surrounding soil is wrapped in arch body and bottom plate, which is formed, to be used
In the corrugated steel outer lining concrete structure of underground pipe gallery.
The utility model provides the corrugated steel outer lining concrete structure form of pipe gallery, and the structure type is due to ripple
The presence of plate, so that the anti-settlement of foundation performance of structure, anti-permeability performance, which has, to be increased substantially；And in pouring construction,
Corrugated steel plays template action, accelerates construction speed；There is structure type segment connection again, flexible connection can be used,
Easy to connect, the leak preventing effect of linkage section is excellent；Additionally due to the presence of outer concrete, also ensures the steady of corrugated steel itself
It is qualitative.This kind of structure type be widely portable to underground pipe gallery construction in, especially suitable for piping lane water level located underground with
Under, ground situation is poor, bearing load is horizontal higher or using in the biggish environment of span.
Prefabricated assembled construction can be used in corrugated steel outer lining concrete structure of the utility model for underground pipe gallery
Mode, for prefabricated construction, bottom plate with arch body can be integral prefabricated, can also bottom plate it is cast-in-place, arch body it is prefabricated.
Compared with concrete pipe gallery, the utility model corrugated steel outer lining concrete structure construction speed faster, structure
Anti-permeability performance, the property easy to connect of the performance and precast section of resisting uneven settlement of foundation, which has, to be increased substantially；With
A possibility that corrugated steel pipe gallery is compared, and the bearing capacity of structure is higher, substantially reduces local buckling, and section form
More diversified, the utilization rate of such as box-type section, the space in section is higher.
Corrugated steel outer lining concrete structure of the utility model for underground pipe gallery includes following beneficial effect：
1, corrugated steel outer lining concrete structure form is due to the presence of corrugated steel, so that structure is impervious, anti-ground is not
The performance of uniform settlement is significantly increased, and structure is less prone to cracking, drainage；
2, corrugated steel outer lining concrete structure form, since corrugated steel can be used as template, is accelerated when segment is poured
Construction speed, while reducing the usage amount of template；
3, prefabricated construction can be used in corrugated steel outer lining concrete structure form, and speed of application is fast, easy to connect, and junction
The anti-permeability performance of structure and anti-differential settlement performance are all very excellent；
4, corrugated steel outer lining concrete structure form is due to the presence of concrete, and integrally-built bearing capacity and stability are all
Significantly larger than corrugated steel construction, suitable for the Pipe rack of large space；
5, corrugated steel outer lining concrete structure form due to concrete presence, the later period backfill the soil body when, do not need picture
Corrugated steel requirement so severe when backfilling, reduces the limitation of construction；
6, its section form of corrugated steel outer lining concrete structure form is freer, can be each using box, semicircle etc.
Kind opening section, such as the box-type section of large span, the internal larger moment of flexure generated can also be undertaken.
The corrugated steel outer lining concrete structure form of pipe gallery described in the utility model is built applied to pipe gallery.
