Abstract
The utility model relates to a hanging basket for a suspension pouring arched bridge, which comprises a hanging basket rack and a walking mechanism. The hanging basket rack comprises a side truss, a main support beam, an underframe, a bottom template, an inner die support, an inner die, an outer die and a front support. The walking mechanism comprises a propulsion cylinder, a support frame for fixing the propulsion cylinder, and a driving device for the propulsion cylinder. The hanging basket also comprises a hydraulic jack and a triangular support mechanism. The hydraulic jack controls the elevating of a main support beam. The triangular support mechanism comprises a support, a fixing base and a first hydraulic cylinder. The two ends of the first hydraulic cylinder are respectively connected with the support and the fixing base. An arched bridge is divided into a plurality of straight line segments through the hanging basket of the utility model, so that the construction is simplified. Meanwhile, the hydraulic jack is arranged on the main support beam so as to realize the integrally hydraulic demoulding. In addition, the continuous operation is realized due to the arrangement of the walking mechanism. Therefore, the hanging basket ensures the construction of an arched bridge when the arched bridge can not be erected while no prefabricated places are provided.
Description
Technical field
the utility model belongs to the bridge construction construction field, particularly a kind of Hanging Basket of cantilever arch bridge.
Background technology
are present, and the main design bridge type of mountain area bridge has freely-supported bridge, continuous rigid frame bridge, cable stayed bridge, arch bridge etc.Freely-supported bridge foundation and bridge pier are more, and it is more loaded down with trivial details to construct, and also bigger to the influence of environment, are only applicable to the more shallow and little gully landform of span of ditch depth; Continuous rigid frame bridge and cable stayed bridge can adapt to bigger ditch depth and span; But the position of bridge pier need be considered the cooperation of end bay and arrange; The layout on main pier and basis often is positioned near the ditch heart, needs that generally main pier is carried out erosion control and handles, and also needs simultaneously main pier side slope is done protective treatment; Therefore, the workload of maintenance is bigger; Arch bridge can well overcome the shortcoming of above-mentioned bridge type, is convenient to maintenance, and cost economic is durable in use.Yet at the arch bridge of large-span steel-reinforced concrete, adopt prefabricated, hanging method or adopt the method for full hall formula bow member to build, but do not have prefabricated place when running into deep mountain valleys, in the time of can't setting up bow member again, just can't build.
Chinese patent ZL200620035365.9 discloses a kind of side purlin Hanging Basket of cantilever arch bridge; This Hanging Basket comprises two side truss, rear support, shearing resistance mechanism, reaction wheel and walking mechanism and template system; Through the adjusting of shearing resistance mechanism, under reaction wheel and walking mechanism effect, realize the continuous placing purpose.Yet Hanging Basket in this patent can not reach the whole demoulding, and workload is big, influences the duration of engineering easily.
