Cover culvert for pipeline protection and its construction method

Abstract

The invention relates to a cover plate culvert for pipeline protection, including backfilling original soil, triangular trusses, foam concrete, installation points, isolation ground connection walls, pipes, geogrids, geotextiles and water-impermeable membranes; the isolation ground connection walls It is arranged on both sides of the pipeline, the installation point is set on the top of the isolated ground connection wall, the triangular truss is arranged across the isolation ground connection wall through the installation point, the foam concrete is arranged in the triangular truss, and the geogrid The geotextile and the water-impermeable membrane are sequentially arranged on the triangular truss filled with foam concrete from bottom to top, and the backfilling original soil is arranged above the water-impermeable membrane. The beneficial effects of the present invention are: compared with the traditional technology, the excavation volume and filling volume of the present invention are greatly reduced, the original state of the soil around the pipeline is maintained, and the technical advantages are remarkable; the triangular truss used in the present invention 1. Foam concrete can significantly reduce the covering load on 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
