Embodiment 1

[0042] A steel pipe arch bridge has a total of nine cross-bracing tube assemblies between two arch ribs. The cross-bracing pipe assembly is composed of four cross-bracing pipes. The two ends of the cross-bracing pipes are respectively connected to the two arch ribs 1 of the steel pipe bridge; The four horizontal tubes in each horizontal tube assembly are the first horizontal tube 2, the second horizontal tube 3, the third horizontal tube 4 and the fourth horizontal tube 5 according to the elevation from bottom to top. The bridge has a total of thirty-six transverse braces. Such as figure 1 As shown, it is a structural schematic diagram of the environmental position relationship of the transverse brace tubes between the arch ribs of some steel pipe bridges. figure 2 and image 3 The elevation position relationship of four cross-stay pipes in one cross-stay pipe assembly can be shown in .

Abstract

The invention relates to a pouring method of concrete in a cross-stay tube between arch ribs of a steel pipe bridge. The two ends of the brace tube, wherein, the hole at the bottom of the brace tube is a grouting hole, and the hole at the top of the brace tube is a grout hole; step 2, the first brace tube The grout hole is connected to the grouting hole of the second brace pipe with a pump pipe ..., and the grout hole of the n-1th brace pipe is connected to the grouting hole of the nth brace pipe hole; step 3, connect the concrete delivery pump pipe with the grouting hole of the first cross-bracing pipe, perform concrete pouring, and stop pumping when the concrete flowing out of the grouting hole of the n-th cross-bracing pipe contains aggregate , close the valve of the pump pipe, the pouring of one horizontal support pipe assembly is completed, and the concrete pouring of the next horizontal support pipe assembly is performed. The pouring method can effectively shorten the construction period and improve the safety of construction and environment.

Description

technical field [0001] The invention relates to the technical field of concrete pouring, in particular to a method for pouring concrete in a cross brace tube between arch ribs of a steel pipe bridge. Background technique [0002] The cross brace between the arch ribs of the steel pipe bridge is a structural part connecting two steel pipe arch ribs. The cross brace after pouring concrete can strengthen the strength, rigidity and stability of the steel pipe arch bridge. In general, there are multiple cross-bracing tube assemblies arranged at intervals between steel pipe arch bridges. Each cross-bracing tube assembly is connected by several cross-bracing tubes to two steel pipe arch ribs. connect. [0003] The pouring of concrete in the brace tubes in the prior art is usually to pour the brace tubes in each brace tube assembly one by one, but when the surrounding environment of the steel tube arch bridge is relatively harsh, such as the steel tube arch There are ships or vehi...
