Description

A kind of staggered joint erection comprehensive pipe gallery structure based on prestress system
Technical field
It the utility model is related to a kind of Urban Underground comprehensive pipe gallery structure, more particularly to a kind of mistake based on prestress system Stitch assembled comprehensive pipe gallery structure.
Background technology
The laying method of the pipelines such as conventional electric power, communication and combustion gas is method of directly burring, due to the same road of the laying of various pipelines Construction is difficult to synchronization, causes existing road to be subjected to excavating landfill repeatedly, not only produces traffic and hinders, noise pollution, environmental disruption Deng livelihood issues, the waste of resource and the increase of quantities also result in.
Pipe gallery, can be by a series of municipal pipeline collection such as electric power, heating power, communication as a kind of Underground Extra-long linear structure In in one, by setting the facilities such as special access hole, dog-house, realize management and construction for pipeline integrated system. Quantities and cost are greatly reduced, more effectively make use of city space to optimize urban life environment.State Council in 2014 General office puts into effect《On strengthening the instruction of City Buried Pipeline implementation management》, indicate steady propulsion underground synthesis The construction of piping lane, and will progressively carry out corresponding pilot project.
The technology relative maturity of fluting method cast in situs Pipe rack at present, but simultaneously there is also earthwork it is big, Occupied ground is wide, construction is complicated and efficiency is low, it is long in time limit the defects of.And prefabricated piping lane can realize the concentration metaplasia of piping lane structure Production, improve the quality and producing efficiency of component.The floor space of live windrow is decreased simultaneously, ensure that speed of application.
Existing prefabricated piping lane uses integrated precast Pipe rack more, but integrated precast Pipe rack often volume It is huge and very heavy, it is all more inconvenient during transport and lifting, while also give transporting equipment and hanging device Higher requirement is proposed, there is more potential safety hazard.In consideration of it, the prefabricated piping lane of pin-connected panel has come into engineering site.
Domestic prefabricated assembled Pipe rack has accumulated certain achievement in research at present, such as Chinese publication number CN105256838A discloses a kind of piping lane prefabricated component and prefabricated pipe gallery.It is prefabricated that Pipe rack is decomposed into three groove profiles Part.The horizontal cast in situs upwardly through reserved reinforcement is attached, and is attached on longitudinal direction using prestressed cable.Take into account The structural intergrity of prefabricated component and the convenience of assembling.Chinese utility model publication number CN105256837A discloses a kind of piping lane Prefabricated component and assembled pipe gallery.Piping lane is decomposed into chassis prefabricated component and cover plate prefabricated component, and set respectively at contact surface Groove and projection are put, is easily installed fixation.It is attached by stressing equipment.Chinese utility model publication number CN105625471A discloses a kind of prefabricated pipe gallery.Pipe rack is divided into bottom plate, side plate, divide storehouse plate and Top plate.By setting bellmouth and socket to realize the interim fixation of structure in contact surface.Respective component is realized by steel pipe embedded part Between interconnection.
The existing assembled Pipe rack of comprehensive analysis is visible, and the component of most of assembled piping lanes is still more huge stupid Weight, still there is improved space in the dividing mode of component.Existing assembled piping lane uses straight joint formula splicing structure more, by Rigidity in joint is relatively small, and the assembling of straight joint formula will cause integrally-built Stiffness Distribution uneven, influence the entirety of structure Rigidity, it is impervious to structure unfavorable.It is most that prestress anchoraging means are only taken on longitudinally connected in terms of the connection of component, it is horizontal Connection between section upper member is relatively weak, have impact on the globality of structure.Simultaneously existing assembled Pipe rack for The setting of joint waterproof details does not provide detailed specification.
