Abstract
The invention relates to a cover plate culvert type high-pressure gas pipeline protection structure which comprises fender posts, enclosing purlins, supports, prefabricated cover plates, cast-in-place reinforced concrete retaining walls and medium coarse sand, wherein two ends of each support are respectively connected with the fender posts through the enclosing purlins to form a fender structure; the enclosure structure is arranged in the construction space of the high-pressure gas pipeline and used for ensuring the construction space and the construction safety of the construction cover plate culvert high-pressure gas pipeline protection structure; the two end covers of the prefabricated cover plate form a gate-type structure on the cast-in-place reinforced concrete retaining wall, and the gate-type structure is arranged outside the high-pressure gas pipeline and is used for bearing road pavement load above the high-pressure gas pipeline; coarse sand in the gate structure is filled back inside and outside. The cover plate culvert type high-pressure gas pipeline protection structure is clear in stress and strong in protection capacity, can effectively isolate various loads from road surfaces above the high-pressure gas pipeline, and is suitable for protecting the high-pressure gas pipeline in an urban soft soil stratum.
Description
Technical Field
The invention relates to a cover plate culvert type high-pressure gas pipeline protection structure, in particular to a construction technology of groove enclosure, cast-in-place reinforced concrete retaining wall, cover plate culvert and backfill.
Background
Along with the development of cities, road reconstruction and expansion projects are increasing. The high-pressure gas pipelines which are not moved on the two sides of the original road are influenced by road widening and are positioned below the road widening projection. In order to protect the high-pressure gas pipeline from being extruded by vertical load, a cover plate culvert type high-pressure gas pipeline protection structure is urgently needed.
Disclosure of Invention
The invention provides a cover plate culvert type high-pressure gas pipeline protection structure which is clear in stress and strong in protection capability and can effectively isolate various loads from a road surface above a high-pressure gas pipeline.
In order to achieve the purpose, the technical scheme of the invention is as follows: a cover plate culvert type high-pressure gas pipeline protection structure comprises fender piles, enclosing purlins, supports, prefabricated cover plates, cast-in-place reinforced concrete retaining walls and medium coarse sand, wherein two ends of each support are connected with the fender piles through the enclosing purlins to form the fender structure; the enclosure structure is arranged in the construction space of the high-pressure gas pipeline and used for ensuring the construction space and the construction safety of the construction cover plate culvert high-pressure gas pipeline protection structure; the two end covers of the prefabricated cover plate form a gate-type structure on the cast-in-place reinforced concrete retaining wall, and the gate-type structure is arranged outside the high-pressure gas pipeline and is used for bearing road pavement load above the high-pressure gas pipeline; coarse sand in the gate structure is filled back inside and outside.
Further, the fender pile is one of a steel sheet pile, a precast pile, a cast-in-place pile and an underground continuous wall.
Furthermore, the purlin is made of profile steel or reinforced concrete.
Further, the support is made of steel sections or reinforced concrete.
Further, the bottom mark of the cast-in-place reinforced concrete retaining wall is lower than the bottom elevation of the high-pressure gas pipeline.
The beneficial results of the invention are: the cover plate culvert type high-pressure gas pipeline protection structure is clear in stress and strong in protection capacity, and can effectively isolate various loads from road pavements above the high-pressure gas pipeline.

Detailed Description
The invention is further described with reference to the following figures and examples.
As shown in fig. 1 to 3, the cover plate culvert type high-pressure gas pipeline protection structure comprises fender piles 1, surrounding purlins 2, supports 3, prefabricated cover plates 4, a cast-in-situ reinforced concrete retaining wall 5 and medium coarse sand 6. Two ends of the support 3 are respectively connected with the fender post 1 through a purlin 2. The enclosing structure is arranged in the construction space of the high-pressure gas pipeline 7, and the enclosing structure consisting of the enclosing piles 1, the enclosing purlins 2 and the supports 3 is used for ensuring the construction space and the construction safety of the construction cover plate culvert high-pressure gas pipeline 7 protection structure. Two end covers of the prefabricated cover plate 4 form a gate-type structure on the cast-in-place reinforced concrete retaining wall 5, and the gate-type structure is arranged outside the high-pressure gas pipeline 7 and mainly bears road pavement load above the high-pressure gas pipeline 7. The mechanical property of the coarse sand 6 in the internal and external backfill of the gate-type structure is excellent, and the gate-type structure is an excellent backfill material.
The fender post 1 is one of a steel sheet pile, a precast pile, a cast-in-place pile and an underground continuous wall. The purlin 2 is made of profile steel or reinforced concrete. The support 3 is made of steel sections or reinforced concrete.
The concrete construction process of the invention is as follows:
firstly, hammering double rows of profile steels outside the safety distance of the high-pressure gas pipeline, installing profile steel purlins in the direction parallel to the pipeline, installing transverse profile steel supports in the direction perpendicular to the pipeline, and excavating a foundation pit to implement cast-in-situ reinforced concrete retaining walls on two sides of the high-pressure gas pipeline. The dense medium coarse sand is backfilled layer by layer inside and outside the retaining wall, and two end covers of the prefabricated cover plate are arranged on the cast-in-place reinforced concrete retaining wall.
