Problems solved by technology

[0007] However, the above-mentioned masonry arch bridge has strict requirements on the lateral thrust of the broken soil at the foot of the arch due to the weakness of the arch bridge structure itself.
This condition limits the use of the structure on soft foundations, e.g. river banks with a lot of silt

Embodiment 1

[0035] One of the specific implementations of a reinforced portable integral prefabricated masonry arch bridge of the present invention, such as figure 1 As shown, it includes a bridge body 3 and a bridge deck 2. The inner side of the bridge body 3 is provided with an arch ring 1. The arch ring 1 includes a main body composed of a plurality of prefabricated arch blocks 11 arranged in sequence, and is fixedly pasted on The fiber reinforced composite material connection layer 12 on the upper surface of the main body, the sides of two adjacent prefabricated arch blocks 11 are attached to each other, and the lower surfaces of all the prefabricated arch blocks 11 form the lower surface of the arch ring 1, the The connecting layer 12 of fiber reinforced composite material is fixedly connected with the upper surface of each prefabricated arch block 11 . Above-mentioned technical feature is identical with the structure of portable whole prefabricated masonry arch bridge in the prior a...

Embodiment 2

[0042] The second embodiment of a reinforced portable integral prefabricated masonry arch bridge of the present invention, as figure 2 As shown, the main technical solutions of this embodiment are the same as those of Embodiment 1, and the features not explained in this embodiment are explained in Embodiment 1, and will not be repeated here. The difference between this embodiment and Embodiment 1 is that: the bottom end of the arch foot of the bridge body 3 is provided with an abutment 7, and the abutment 7 is closely connected with the bottom end of the arch foot of the bridge body 3, The transverse tie rods 4 are arranged between the abutments 7 .

Embodiment 3

[0044] The third specific embodiment of a reinforced portable integral prefabricated masonry arch bridge of the present invention, the main technical solution of this embodiment is the same as that of embodiment 1, and the features not explained in this embodiment shall be explained in embodiment 1 , which will not be repeated here. The difference between this embodiment and Embodiment 1 is that: the middle part of the transverse tie rod 4 is provided with a pre-tensioning member. Pretension is provided by pretension elements.

[0045] Specifically, the pre-tensioning member is a bolt sleeve 5 . The bolt sleeve 5 is a bolt sleeve 5 with an internal thread.

[0046] Specifically, the bolt sleeve 5 is made of stainless steel. The effect in practical application is better, and it is not easy to be damaged, and the service life is longer.

[0047] Specifically, the bolt sleeve 5 is made of fiber reinforced plastic (FRP).

Abstract

The invention relates to the technical field of arch bridges, in particular to a reinforced portable integral prefabricated masonry arch bridge, which comprises a bridge body and a bridge deck, wherein the inner side of the bridge body is provided with an arch ring; the arch ring comprises a main body consisting of a plurality of prefabricated arch blocks arranged in turn, and a fiber reinforced composite material connecting layer fixedly attached to the upper surface of the main body; side faces of every two adjacent prefabricated arch blocks are attached to each other; lower surfaces of all prefabricated arch blocks form a lower surface of the arch ring; the fiber reinforced composite material connecting layer is fixedly connected with the upper surface of each prefabricated arch block; a transverse pull rod is arranged between arch feet of the bridge body; and two ends of the transverse pull rod are fixedly connected with the bridge body through bolts. Compared with the prior art, the transverse pull rod is arranged between the arch feet of the bridge body and is used for providing self lateral restriction for an arch body, so that the bearing capacity and stability of the arch bridge structure are improved and the arch bridge can be applied to soft foundations.

Description

technical field [0001] The invention relates to the technical field of arch bridges, in particular to a reinforced portable integral prefabricated masonry arch bridge. Background technique [0002] At present, the bridge structure with reinforced concrete as the main building material is more prone to the problem of decreased durability due to corrosion of steel bars after a short period of use, resulting in a sharp increase in maintenance costs, and even loss of traffic carrying capacity. ability. [0003] In view of the above-mentioned problems, masonry arch bridges have become an effective way to solve the above-mentioned durability problems due to their special mechanical properties and low use of steel bars. The so-called masonry arch bridge is an arch bridge built by making full use of masonry materials (such as: stone, concrete, brick, etc.) with poor tensile properties and good compressive properties. [0004] However, masonry arch bridges in the prior art are rest...
