Abstract

The utility model discloses an anti-floating structure of a buried pipeline. The anti-floating structure comprises a buried pipeline (1); backfill (2) is arranged on the buried pipeline; an anti-floating plate is arranged above or below the buried pipeline; and embedded bars (4) are arranged on the lower anti-floating plate and are connected with the buried pipeline. The anti-floating plate above the buried pipeline prevents the buried pipeline from floating; or the anti-floating plate below the buried pipeline is connected with the buried pipeline to prevent the buried pipeline from floating. The downward projection area of the anti-floating plate is far larger than that of the buried pipeline, so the backfill generates far higher pressure on the anti-floating plate than on the buried pipeline to effectively prevent the buried pipeline from floating. By the anti-floating plate technical scheme, the buried pipeline is not required to be buried deeply and can meet the anti-floating requirement. The anti-floating structure has the characteristics of simple structure, practicality, quick construction, no need of deeply burying the pipeline, and low construction cost.

Description

A kind of buried pipeline float Structure

Technical field

the utility model relates to a kind of buried pipeline float Structure, belongs to the pipe laying technical field.

Background technique

in pipe conveying procedure, for the length that shortens pipeline with bury cost underground, reduce construction investment, much the conveyance conduit of long distance usually can be along the river course edge placement or cross a river arrange.Because pipeline receives the restriction of the factor of technology and geological condition, the thickness of earth covering of pipeline top can be very not thick usually, and when river flood during the phase, the river water level goes up, and pipeline is formed bigger buoyancy, and when particularly meeting the pipeline blank pipe, buoyancy is bigger.Can't satisfy the anti-floating requirement of pipeline.Present way is: in order to satisfy the anti-floating requirement of pipeline, adopt buried mode, improve the earthwork weight of pipeline top.This has just caused the engineering work load of the cubic metre of earth and stone sharply to strengthen, and edge, road buried pipeline can shorten duct length though adopt along the river, reduces cost of material, and engineering cost increases a lot, can't apply.

Summary of the invention

The purpose of the utility model is, a kind of buried pipeline float Structure is provided, and can either solve the anti-floating problem under the pipeline emptying operating mode, has also well solved the problem that buried engineering work load of bringing of pipeline and cost of investment increase.Have characteristics simple in structure, practical, quick construction.

The technological scheme of the utility model

a kind of buried pipeline float Structure comprises buried pipeline, and the buried pipeline top is provided with backfill; Above or below buried pipeline, be provided with the anti-floating plate, on the anti-floating plate of below embedded bar be set, embedded bar is connected with buried pipeline.

In aforementioned buried pipeline float Structure, the downward projection area of said anti-floating plate is greater than the downward projection area of buried pipeline.

In aforementioned buried pipeline float Structure, be provided with cyclopean concrete around the buried pipeline of said anti-floating plate top and assure.

In aforementioned buried pipeline float Structure, said anti-floating plate is C20 armoured concrete slab or anticorrosion plank.

compared with prior art, the utility model stops the buried pipe come-up through the anti-kickboard above buried pipe; Or the anti-kickboard of passing through the buried pipe below is connected prevention buried pipe come-up with buried pipe.Because the downward projection area of anti-kickboard much larger than the downward projection area of buried pipe, so backfill can produce much larger than at the buried pipe upward pressure, has effectively stoped the buried pipe come-up on anti-kickboard.Because the utility model has adopted the technological scheme of anti-kickboard, thus buried pipe when burying underground, need not bury just can make buried pipe reach the anti-floating requirement very deeply.Have simple in structure, practical, quick construction, need not buried, the characteristics that construction cost is low.

Being labeled as in accompanying drawing: the 1-buried pipeline, the 2-backfill, 3-anti-floating plate, the 4-embedded bar, the 5-cyclopean concrete is assured.

Embodiment

are further described the utility model below in conjunction with accompanying drawing and embodiment, but not as the foundation to the utility model restriction.
