Embodiment

[0046] see figure 1 - Figure 4 , the present embodiment provides a kind of high slope bridge construction technology based on the existing railway line, the construction technology includes the following steps:

[0047] Step 100, carry out the construction of protective pile 100 at the position of the lower slope 10 where the existing railway line 800 is set, wherein the protective pile 100 is drilled at the set position before the installation of the protective pile 100, and after the drilling is completed, a reinforcement cage is placed in the drilled hole 1. Pouring concrete to form a reinforced concrete structure, and then reinforcing to form protective piles 100 . The number of protective piles 100 and the diameter of each protective pile 100 can be set as required, and are not specifically limited here.

[0048] Optionally, during the construction process of the protection pile 100, holes are formed by rotary drilling and manual assistance, and the protection pile 100...

Abstract

The invention provides a high slope bridge construction technology based on an existing railway, which comprises the following steps of: performing construction of protective piles on the low slop position provided with an existing railway, arranging an isolation retaining wall on the lower side of the low slope, arranging an protective retaining wall on the higher side of the up slope provided with an existing railway, arranging a protective mesh on one side of the protective retaining wall, away from the up slope, arranging a first pier at the lower part of the low slope, wherein the first pier is one side of the isolation retaining wall, deviating from the up slop excavating the high side of the up slop, arranging a second pier at the excavation position, wherein the protective retaining wall is positioned between the second pier and the railway. When the bridge construction is carried out, the technology has the advantages of good protection effect, nearly no collapse in the construction process, nearly no rolling stones and safe and reliable construction.

Description

technical field [0001] The invention relates to the field of bridge engineering, in particular to a construction technique for high slope bridges based on existing railway lines. Background technique [0002] For the long-distance transportation of bulk goods and people, railway transportation has the characteristics of large transportation volume and low transportation cost, and occupies an important position in the comprehensive transportation system. At present, most large and medium-sized cities in China have railway lines passing through them. Railways passing through cities provide great convenience for the transportation of passengers and goods outside the city, but at the same time, they also bring difficulties to urban construction and transportation. With the rapid development of the national economy, there are more and more new traffic forms such as expressways, municipal roads, and railways. The lines that have not reserved new road passage windows must cross the...
