Detailed Description
The technical solutions (including the preferred technical solutions) of the present invention are further described in detail by referring to fig. 1 to fig. 4 and some alternative embodiments of the present invention, and any technical features and any technical solutions in the present embodiment do not limit the protection scope of the present invention.
As shown in fig. 1 to 3, the bridge with both water delivery and traffic functions designed by the invention comprises a bridge abutment 1, a bridge pier 2 and a box girder 3; the box girder 3 is loaded on the bridge abutment 1 at both sides of the valley and the bridge pier 2 at the middle of the valley arranged at intervals; the box girder 3 is a prestressed reinforced concrete structure, is mostly a simply supported box girder, generally adopts standard spans of 24m and 32m, and is prefabricated in an industrial manner;
a through long water delivery pipe 4 is arranged in the box girder 3 along the longitudinal bridge direction, and two ends of the water delivery pipe 4 penetrate out of a through hole 1.1 reserved on the abutment 1; a plurality of bases 5 for bearing and fixing the water delivery pipes 4 are arranged on the bottom surface of the inner wall of the box girder 3 at intervals; the base 5 comprises a base platform 5.1 fixed with the bottom surface of the inner wall of the box girder 3 and an arc-shaped plate 5.2 positioned at the top of the base platform 5.1 and used for bearing the water delivery pipe 4, and a shock pad (not shown in the figure) is arranged between the arc-shaped plate 5.2 and the water delivery pipe 4; along the longitudinal bridge to, the lower one end is equipped with condensate collecting tank 6 in every section case roof beam 3, condensate collecting tank 6 is located raceway 4 below for thereby collect because of the high temperature air meets the low temperature pipeline condensation and forms the comdenstion water in case roof beam 3, and then forms rivers, leads to the durability problem of case roof beam 3. Arranging the water duct 4 inside the box girder 3 mainly has several problems: the influence of the vibration of the running high-speed train on the water conveying pipe 4, the influence of the vibration of Chen Sheng on the bridge in the water conveying process of the water conveying pipe 4 and the vibration of the front two will not generate resonance, prevent and treat. The invention separates the water delivery pipe 4 and the box girder 3 relatively independently through the base 5, so that the interference between the water delivery pipe 4 and the box girder is avoided, thereby solving the technical problem.
Because the box girder 3 is prefabricated, the box girder can generate certain displacement or vibration in the process of high-speed train moving, and the water conveying pipes 4 arranged in the box girder 3 can be influenced by a certain amount. For this purpose, the water duct 4 preferably comprises a standard section 4.1 and a connecting section 4.2; only one standard section 4.1 is arranged in each section of box girder 3, the length of the standard section 4.1 is smaller than that of the box girder 3, and the standard sections 4.1 between the adjacent box girders 3 are connected through a connecting section 4.2; the standard section 4.1 is a rigid pipeline and is fixedly supported on the base 5; the connecting section 4.2 is a flexible pipe. The standard section 4.1 is mostly made of a relatively light material under the premise of equal water delivery quantity, and is a round pipe with excellent durability, impermeability and pressure resistance; on the premise of meeting basic performances such as impermeability and pressure resistance, the connecting section 4.2 needs to have high-quality bending resistance and fatigue resistance, can meet the fatigue of a joint section caused by the deflection of a beam during the operation of a high-speed railway, has a longitudinal expansion function, and can adjust the expansion deformation of a longitudinal pipeline caused by temperature difference change. Further preferably, the standard section 4.1 is a steel pipe and/or a prestressed concrete pipe; the connecting section 4.2 is a rubber corrugated pipe.
Preferably, the distance between the bases 5 is determined comprehensively according to the diameter and the rigidity of the water conveying pipe 4, and the distance between the bases in each section of box girder 3 is 5-10 m.
As shown in fig. 4, in order to ensure water supply, as a preferred scheme, two parallel water pipes 4 are arranged in the box girder 3, and at least two transverse pipes 7 communicated with the water pipes 4 are arranged between the two water pipes 4 at intervals; and both ends of the water conveying pipe 4 between the transverse pipes 7 and the adjacent transverse pipes 7 are respectively provided with a valve 8. Specifically, the control valve 8a on the transverse pipe 7 is closed in the normal working state. When the local part of the pipeline needs to be maintained, the function of local maintenance of the pipeline without integral cutoff can be realized by adjusting the control valve 8, opening the valve 8a, closing the valve 8b and opening the valve 8c (under the normal condition, 8b and 8c are both opened).
