Cover plate culvert for pipeline protection and construction method thereof

Abstract

The invention relates to a cover plate culvert for pipeline protection. The cover plate culvert comprises backfill original soil, a triangular truss, foam concrete, mounting points, isolation diaphragm walls, a pipeline, geogrid, geotextile and an impermeable membrane. The isolation diaphragm walls are arranged on the two sides of the pipeline, the mounting points are arranged at the tops of the isolation diaphragm walls, the triangular truss is arranged on the isolation diaphragm walls in a crossing mode through the mounting points, the foam concrete is arranged in the triangular truss, the geogrid, the geotextile and the impermeable membrane are sequentially arranged on the triangular truss filled with the foam concrete from bottom to top, and the backfill original soil is arranged abovethe impermeable membrane. The cover plate culvert has the beneficial effects that compared with the prior art, the soil engineering excavation amount and the fill amount are greatly reduced, an original state of a soil body around the pipeline is kept, and the technical advantages are remarkable; and the triangular truss and the foam concrete adopted by the cover plate culvert can obviously reduce the covering load of the upper part of the pipeline.

Description

technical field [0001] The invention relates to a slab culvert, in particular to a slab culvert for pipeline protection and a construction method thereof. Background technique [0002] With the continuous development of traffic bridges and urban construction, the underground pipeline transportation network is also becoming more and more developed. Since the pipeline lines are generally long, crossing provinces, cities, and even countries, existing roads and new projects will definitely be encountered during the construction phase and later operation. How to avoid the deformation and damage of underground crossing pipelines caused by soil disturbance, load settlement and vehicle traffic caused by embankment deformation caused by new construction, the traditional pipeline protection method is to build reinforced concrete slab culverts. The current existing pipeline protection patent technologies include: CN201410214006.9, CN201420255747.7, CN201220689049.9, CN201420174188.7, ...

Problems solved by technology

The current existing patented technologies for pipeline protection include: CN201410214006.9, CN201420255747.7, CN201220689049.9, CN201420174188.7, CN201710137205.8, CN201920753012.X, CN201620481911.5 and CN201420. There are many problems, such as: a large amount of earthwork needs to be filled and excavated during the construction of the slab culvert, and the depth of the excavation is deep, which seriously disturbs the original soil and brings hidden dangers to the original buildings around. Moreover, the amount of reinforced concrete in these patents is generally large , it will cause the cover culvert to be self-heavy, and it is easy to deform, crack, leak or accumulate water under the action of high filling load, and it is also easy to be slowly eroded, which cannot play a good role in protecting the pipeline for a long time
