Embodiment Construction

[0017] 1. Make Φ1500mm C25 concrete piles on both sides of the railway sleepers to be reinforced. The pile distance on the same side of the railway is 10m, and the pile distance on both sides of the railway is 4.0m. The pile depth is 0.5m deeper than the buried pipeline or the bottom of the foundation. M4-139 embedded parts are pre-embedded at the top of the pile.

[0018] Due to the narrow construction site of the railway line, in order to avoid subsidence accidents caused by large-scale excavation, refer to the construction method of manual excavation piles, and use DN1500 welded steel pipe artificial caisson method for construction. The advantage of manual hole-digging piles is that no construction machinery is required, the operation is simple, the site occupation is small, and the surrounding buildings are not affected; the pile diameter and verticality requirements can be guaranteed.

[0019] Weld four short legs with a length of 100mm to the bottom of the steel pipe. Af...

Abstract

The invention relates to a railway reinforced construction method, belonging to the technical field of railway engineering. The method comprises the following construction steps: reinforced concrete pile foundations are respectively manufactured at two sides of a line which affects the railway service; profile steel is arranged at the top of the pile foundation as a supporting beam after the concrete pile foundation reaches the required intensity; and reinforced steel rails are arranged at the top of the beam at interval along the railway sleepers for supporting the running railway. The railway reinforced construction method has the advantages that: the profile steel and the concrete piles are used for reinforcing the running railway according to the distance of the sleepers, the stress relations between the steel rail and the sleeper and between the sleeper and the road bed are transferred to the profile steel and the concrete pile which have the supporting function, so as to realize tunneling and excavation of the road bed of the railway. The production operation is not affected, valuable construction period for engineering construction is saved, the difficult problems of railway underground engineering construction and railway transportation confliction are effectively solved, and good economic technical benefits are obtained.

Description

technical field [0001] The invention belongs to the technical field of railway engineering, and in particular provides a construction method for railway reinforcement, which is suitable for transportation engineering. Background technique [0002] During the construction of supporting facilities for Shougang Qiangang Company, the construction of civil foundations and underground comprehensive pipe networks in various regions inevitably encountered problems such as crossing and conflicting with railway transportation lines. The construction of underground works will affect the safety of railway traffic. According to the conventional practice, the construction of railway breaks will seriously affect the production and operation and the construction period. [0003] The foundation of the newly built 3Q2 corridor of the raw material station of Qiangang is too close to the rail line railway of the raw material station, the 10# line railway, and the 1 and 2# line turnouts, which a...
