Description
Technical field
The invention belongs to tunnel pipelines technical field, particularly a kind of heating power shield tunnel guiding trestle.
Background technology
Along with the development in China city, central heating becomes the important way of urban heat supplying, builds heating power tunnel and concentrates the preferred manner of settling heating pipeline to become city central heating.But because the urban ground space of China is mostly comparatively valuable, and the underground space also approaches saturatedly gradually afterwards by the exploitation of various uses, and available space is to the utmost is limited, and developing second layer space becomes the important topic that current heating power tunnel construction must be faced.
At present heating power tunnel main construction method---there is many limiting factors in-shallow burial hidden digging, the needs of the city thermal engineering construction of China can not have been met, aging along with old heat distribution pipeline, and the layout demand of new heat distribution pipe network, within a period of time, in city, the heating power tunnel that needs excavation will constantly be had.For the ease of its exploitation of the underground space in the future, shield method is more and more applied to the excavation in heating power tunnel, heating power shield tunnel is to advance at deep under ground by shield machine tool, by shield structure shell and section of jurisdiction supporting surrounding country rock, prevent toward caving in tunnel, in excavation face the place ahead, with topping machanism, carry out soil excavation simultaneously, by the machinery that is unearthed, transport outside hole, form a kind of mechanized construction method of tunnel structure.Compare with traditional shallow burial hidden digging, it is fast that shield method has speed of application, and labour intensity is low, do not affect traffic above-ground and facility, and the construction operation degree of depth does not more affect the advantages such as facility such as existing underground utilities simultaneously.
In current heating power shield tunnel is built, substantially first by shield machine, at deep under ground, dig out dark hole, then by what be spliced into, form and can hold heating power for the tunnel of, water return pipeline with the suitable annular section of jurisdiction of dark hole dia, now the outermost layer barrier in Ze Shi tunnel, annular section of jurisdiction, is bearing the effect of resisting soil layer pressure, groundwater pressure and some special loads.And the permanent lining, secondary lining structure of annular section of jurisdiction is directly connected to total quality and the safety in tunnel, affects water resistance and the endurance quality of heating power shield tunnel.
In existing heating power shield tunnel, be typically provided with the guiding trestle that can penetrate heat distribution pipeline, guiding trestle is to make the support that pipeline can only be mobile vertically, and stops the rotation causing because of moment of flexure or moment of torsion.Because the reason of structure often has the effect of limit lateral linear displacement concurrently, and guiding trestle also can be given the supporting role certain with thermal shield tunnel segment simultaneously.Generally, existing guiding trestle is directly to anchor in the bar construction of tunnel ring-shaped section of jurisdiction, Pouring concrete at the same time starts moulding, this structure can not be guaranteed stability long-term effectively, and owing to anchoring into concrete structure, make when needing repairing transposing support or needing adjusting pole position, bother very much, and the integrated support intensity of as easy as rolling off a log destruction support, therefore adopt which kind of guiding trestle structure and and section of jurisdiction between connected mode in order to bear the lateral thrust of heat distribution pipeline, make the displacement of heat distribution pipeline restriction other directions except axially, the support of effectively bearing again above-mentioned other active force has become one of technical barrier of current shield tunnel project quality simultaneously.
Summary of the invention
