Abstract
The utility model discloses a redundant formula vertical braces structure for protection of 220kV cable normal position, propping girder and many spinal branchs and propping auxiliary girder including fixing two a radicles supporting beam, two spinal branchs in truss below, two spinal branchs prop two third position departments that the girder is located the truss respectively, and a tip supporting beam's both ends are adopted and are located the outer bored concrete pile of foundation ditch and support, support the both ends of girder and adopt the steel lattice column that is located the foundation ditch to support, and even in the wall, the both ends adoption of supporting auxiliary girder is located the shaped steel stand support of foundation ditch for the pre -buried ground under the structure roof in bottom of steel lattice column. Adopt the utility model discloses, the be convenient for recovering of roof construction, the box culvert of being convenient for. The utility model discloses divide large -span structure into a plurality of little span structures, reduced the deformation of truss by a wide margin, optimized the stress of truss, improved the security. The utility model discloses follow segmentation support and redundancy design's principle, be main and secondary two parts with the bearing structure design, make things convenient for the construction of roof and the recovering of box culvert.
Description
Technical field
The utility model relates to a kind of in-situ conservation structure of cable, particularly a kind of redundance type vertical supporting 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 vertical supporting structure of truss just becomes the technical problem that current urgent need solves so.
Summary of the invention
The utility model provides a kind of redundance type vertical supporting structure for 220kV cable in-situ conservation for solving the technical problem existing in known technology; this structure can form effectively reliably and support truss, and can facilitate the construction of top board and the recovery of box culvert.
The technical scheme that the utility model is taked for the technical problem existing in solution known technology is: a kind of redundance type vertical supporting structure for 220kV cable in-situ conservation, comprise the two radicle brace summers that are fixed on truss below, two support girders and Duo Gen support auxiliary beam, two described support girders lay respectively at two 1/3rd positions of described truss, the two ends of described end portion supports beam adopt the bored concrete pile being positioned at outside foundation ditch to support, the two ends of described support girder adopt the steel lattice column that is positioned at foundation ditch to support, the bottom of described steel lattice column is embedded in the ground-connecting-wall under structure roof, the two ends of the auxiliary beam of described support adopt the shaped steel upright supports that is positioned at foundation ditch.
The cross section of described shaped steel column is " work " font, and described steel lattice column adopts angle steel to be welded.
Advantage and the good effect that the utlity model has are: truss is fixed on to two radicle brace summers, two support girders and Duo Gen support on auxiliary beam, employing is arranged on the bored concrete pile supporting base end portion brace summer outside foundation ditch, the shaped steel upright supports that employing is positioned at foundation ditch supports auxiliary beam, employing is positioned at the steel lattice column supported girder of foundation ditch, the support of support girder employing steel lattice column is being set apart from 1/3rd places at truss two ends, arrange and support auxiliary beam employing shaped steel upright supports at span centre, before construction top board, adopt steel column sub-truss, in the time doing waterproof roofing, remove shaped steel column, adopt steel lattice column sub-truss, be convenient to top board construction, be convenient to the recovery of box culvert. meanwhile, longspan structure is divided into multiple little span structures by the utility model, significantly reduced the distortion of truss, optimized the stress of truss, improved security, and can be cost-saving. in sum, the utility model is followed the principle of segmentation support and Redundancy Design, is major-minor two parts by support structure designs, facilitates the construction of top board and the recovery of box culvert.
