Detailed Description

The technical solution of the present invention will be further explained with reference to the accompanying drawings.

The multi-span connecting structure is arranged between adjacent bridge plates of a multi-span pipeline, and the multi-span pipeline is formed by two spans and more than two spans of bridge plates in parallel. The connecting structure is used for connecting adjacent bridge plates of pipelines, and the adjacent bridge plates belong to different pipeline cabins. As shown in fig. 1 and 2, in the conventional multi-span structure, when the bridge slab is arched, the force application points on both sides are disposed on the elongated concrete buttresses. When the bridge plate is flat, the support strength is poor. And embedding anchor bolts on the concrete buttress, using angle steel as an intermediate connecting piece, and connecting the angle steel with the corrugated steel plate through bolts. Through the summary and research of the engineering cases of the applicant for many years, the following defects exist in the prior art: (1) the number of bolt holes on the corrugated steel plate and the angle steel is large, and the joint cannot be prevented from leakage; (2) the strip-shaped buttress is cast-in-place concrete, the construction period is long, the strip-shaped buttress generally needs to be used as an expanded foundation, and the foundation requirement is high.

As shown in the structure of embodiment 1 in fig. 3, the multi-span structure of the present invention includes a longitudinal beam 2 disposed between the arch feet of adjacent bridge plates 1 and a connecting member 3 for connecting the longitudinal beam 2 and the bridge plates 1 on both sides. The longitudinal beam is adopted to replace the original concrete buttress structure. The longitudinal beam 2 is a section steel comprising at least one transverse edge 22 and at least one vertical edge 21, such as a channel steel, an i-section steel or an L-angle steel, which can increase the moment of inertia and the strength of the connection structure when the transverse edge is located outside the pipe. The transverse edge 22 is located below the arch foot and faces towards the inner side direction of the spliced pipeline, the transverse edge is used for connecting vertical supports between two bridge plates, the vertical supports are used for separating adjacent unit pipe joints, and the transverse edge can be a cylinder or a wall body and the like. Tension and compression members can be arranged between the longitudinal beams 2 or between the longitudinal beams 2 and the bridge plate 1 to increase the strength of the spliced pipeline.

The bridge plate 1 is abutted against the vertical edge 21 and fixed by the connecting piece 3 and a plurality of bolts. In this embodiment, the connecting member 3 is disposed inside the bridge plate, i.e. in the direction of the inside of the spliced pipeline, and in other embodiments, may also be disposed outside the bridge plate. And (3) welding shear nails and/or paving metal nets on the outer side of the bridge plate 1, and pouring concrete to form a combined structure of the bridge plate and the concrete.

The connecting piece 3 comprises a first folded edge 31 and a second folded edge 32 which are symmetrically arranged at two sides of the longitudinal beam and are used for connecting the longitudinal beam 2 and the bridge plate 1. The first flange 31 is attached to the bridge plate 1 and connected with the bridge plate through the first bolt 4, the second flange 32 is attached to the vertical flange 21 of the longitudinal beam 2, and the second flanges 32 on two sides of the vertical flange are connected through the second bolt 5. When the bridge plate 1 is straight, the included angle between the first folded edge 31 and the second folded edge 32 is 90 degrees; when the bridge plate 1 is arched, the included angle between the first folded edge 31 and the second folded edge 32 is an obtuse angle, and the first folded edge 31 is in an arc shape attached to the arched bridge plate; when the bridge plate 1 is the arch buckled plate, first hem 31 is the arch buckled plate of this bridge plate of laminating, and simultaneously, the position of the tie point of first hem 31 and bridge plate, first bolt 4's position promptly is located the trough 6 department of buckled plate.
