Description
Technical Field
The utility model relates to a municipal works field especially relates to a utility tunnel excavation supporting tubular pile and steel waist roof beam connection structure.
Background
The utility tunnel is an important ring in municipal engineering, namely, a tunnel space is built under the city, various engineering pipelines such as electric power, communication, gas, heat supply, water supply and drainage and the like are integrated, a special overhaul port, a special hoisting port and a special monitoring system are arranged, unified planning, unified design, unified construction and management are implemented, and the utility tunnel is an important infrastructure and a 'life line' for guaranteeing city operation. Wherein generally through built-in fitting welded connection between utility tunnel tubular pile basis and the piping lane support, shift play appears easily when meetting great load and longitudinal vibration, probably leads to appearing the clearance, influences piping lane structure safety.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to prior art's defect and not enough, provide a municipal works utility tunnel tubular pile and steel waist roof beam connection structure, solve generally through built-in fitting welded connection between utility tunnel tubular pile basis and the piping lane support, shift the drunkenness appears easily when meetting great load and longitudinal vibration, probably lead to appearing the clearance, influence the problem of piping lane structure safety.
In order to achieve the purpose, the utility model adopts the technical proposal that: a connection structure of a comprehensive pipe gallery foundation pit supporting tubular pile and a steel waist beam comprises a tubular pile, a pre-buried sleeve, a steel waist beam, a steel corbel and a steel support; the pipe pile is of a precast reinforced concrete row pile structure, a round steel plate is arranged in the pipe pile and serves as a supporting plate, and a concrete filling core is filled on the supporting plate; a layer of embedded sleeve is embedded outside the middle section of the pipe pile, one side of the embedded sleeve is connected with a steel waist beam in a welding mode, and gaps between the embedded sleeve and the steel waist beam are filled and filled with concrete; the bottom surface of the steel waist beam is welded and connected with a steel corbel, the side surface of the steel corbel is fixedly connected with the embedded sleeve, and a stiffening rib which is vertical to the extension direction of the steel waist beam is arranged in the steel waist beam; one side of the steel waist beam back to the tubular pile is fixedly connected with a steel support.
Preferably, the horizontal spacing between the stiffening ribs is not more than 100mm, and the side edges of the stiffening ribs and the steel waist beam are in full-welded connection.
Preferably, the thickness of the embedded sleeve is not less than 8mm, and the length of the embedded sleeve is not less than 500mm.
Preferably, the thickness of the steel corbels is not less than 10mm, and the horizontal distance between the steel corbels is not more than 400mm.
The utility model has the advantages that: the structure forms stable and reliable connection to the tubular pile and the steel support through the steel waist beam, and simultaneously strengthens the bearing and shearing resistance of the steel waist beam by the steel corbels and the stiffening ribs, thereby reducing the risk of displacement and play.
