Abstract
The utility model discloses a horizontal suspension structure for protection of 220kV cable normal position, include the truss of fixing directly over the cable protection box culvert and set up the layer board that suspends in midair below the cable protection box culvert the top of truss is equipped with the multichannel and suspends roof beam, all in midair rather than the vertically suspend the roof beam in midair and evenly arrange the below of suspending the layer board in midair be equipped with the multichannel with that suspends about roof beam one -to -one in midair suspends joist, relative up -down in midair suspend in midair the joist with the both ends of suspending the roof beam in midair respectively link to each other through a chain block. The utility model discloses stable in structure is reliable, non -deformable, and the differential settlement that can guarantee the box culvert is within 2cm. Dynamic adjustment can carry out to adjust very in a flexible way. Can avoid the damage of concrete box culvert among the protection process, strengthen the wholeness of box culvert, make whole box culvert form the ductility structure, can avoid underpining the damage to the box culvert many times, can avoid box culvert differential settlement's production.
Description
Technical field
The utility model relates to a kind of in-situ conservation structure of cable, particularly a kind of horizontal suspension structure for 220kV cable in-situ conservation.
Background technology
In Construction of Urban Rail Traffic process, often can run into various pipelines, major part can be taked to cut the mode changing, and for 220kV and above high-tension cable, needs to carry out in-situ conservation. 220kV and above high-tension cable are arranged in the box culvert of spigot-and-socket conventionally, around box culvert inner cable, are abound with the discrete materials such as yellow sand. In the time carrying out the in-situ conservation of cable, the relative settlement control of box culvert is very strict, generally in 2cm left and right.
In the main structure construction stage in foundation ditch, cable need carry out integrated support protection. Current, in the time adopting lid to dig in reverse construction foundation ditch agent structure, an overfill protection of cable generally adopts the mode of Pipeline Bridge, above structure roof, applies trestle, cable is fixed on to below or a side of trestle. Trestle is supported by the ground-connecting-wall of foundation ditch both sides. This protection structure exists construction complicated, the uppity shortcoming of cable protection box culvert reversed process. In order to solve the problems of the technologies described above, truss suspension protection structure is now proposed, the horizontal suspension structure of cable just becomes the technical problem that current urgent need solves so. Because cable box culvert adopts bell and spigot frame, a little less than contact relative thin, especially, in the situation that repeatedly underpining, more should reinforce or seal processing to it. Next is that relative settlement very easily appears in the distortion of box culvert, therefore need take regulative mode flexibly dynamically to correct for the horizontal suspension structure of cable protection.
Summary of the invention
The utility model provides a kind of horizontal suspension structure for 220kV cable in-situ conservation for solving the technical problem existing in known technology, and this structure can ensure that the relative settlement of box culvert is in 2cm, and is convenient to dynamic adjustments.
The technical scheme that the utility model is taked for the technical problem existing in solution known technology is: a kind of horizontal suspension structure for 220kV cable in-situ conservation, comprise the suspention supporting plate that is fixed on the truss directly over cable protection box culvert and is arranged on cable protection box culvert below, above described truss, be provided with the perpendicular suspention beam of multiple tracks, all described suspention beams are evenly arranged, below described suspention supporting plate, be provided with multiple tracks and described suspention beam suspends joist up and down one to one in midair, the two ends of described suspention joist opposing upper and lower and described suspention beam are respectively connected by a chain block.
Described suspention beam and described suspention joist are all made up of I-steel.
Advantage and the good effect that the utlity model has are: adopt many groups by suspending beam and suspention joist in midair and being connected to the flexible overhung construction that the chain block at their two ends forms, box culvert and inner load thereof are delivered on truss, Stability Analysis of Structures is reliable, not yielding, can ensure that the relative settlement of box culvert is in 2cm. Take chain block to suspend in midair, can carry out dynamic adjustments, and regulate very flexible. Adopt the structure that suspention supporting plate is set below cable protection box culvert; can avoid the damage of concrete box culvert in protection process, strengthen the globality of box culvert simultaneously, make whole box culvert form ductility structure; the damage to box culvert can be avoided repeatedly underpining, the generation of box culvert relative settlement can be avoided.
