Description

A kind of seabed HDPE pipeline saddle weights
Technical field
The utility model is related to a kind of armored concrete saddle weight, and in particular to one kind is used for major diameter seabed HDPE pipelines Armored concrete saddle weight.
Background technology
With expanding economy and the progress of technology, ocean development is also developed rapidly, the construction of offshore pipeline engineering also with It is more and more.Taking and discharging pipeline, continent city of the offshore pipeline engineering mainly including Coastal Thermal Power Plant and nuclear power plant are to offshore Marine blowdown pipeline of fresh water feed-line, coastal cities between island and island and island etc..With offshore pipeline institute often Tubing, such as steel pipe, cast iron pipe are compared with pipe of concrete, and HDPE pipelines have good chemical stability, corrosion resistance and good, height The advantages of toughness and long service life, so HDPE pipelines are widely used all over the world, it is increasingly being applied to sea Sewage vent line, marine taking and discharging pipeline and offshore oil and gas conveyance conduit etc. have the pipeline engineering of particular/special requirement.
Although HDPE pipelines have above advantage, HDPE channel densities are smaller than seawater, even if under full water operating mode, Can be in marine float;Simultaneously during pipeline commissioning, in the presence of wind load, ocean current load and wave load, Pipeline can swing, and deviate predetermined designed lines, so, it is necessary to take underwater pipeline stabilizing measure to cause in construction and running HDPE pipelines are sink to seabed, and it is fixed in designed lines.Conventional underwater pipeline stabilizing measure is to set armored concrete saddle weight, Because the investment of armored concrete saddle weight is relatively saved, strong adaptability, construction technology is ripe, it is easy to which it is excellent that guarantee aggravates underwater pipeline stabilizing quality etc. Point, and widely applied.
Armored concrete saddle weight is generally made up of upper and lower two parts, and the general adoptable shape of saddle weight has:Rectangle, circle Shape and star.Star is applied to ocean current power and wave force than larger operating mode, and difficulty of construction is big, therefore is rarely employed.It is circular Section is because of simple structure, difficulty of construction is small and is often used, but coefficient of friction is smaller, about 0.2, on-bottom stability It is not enough;Being applied in the groove of sea bed circular saddle weight, to topography and geomorphology higher, the geological conditions adaptability of requirement of sea bed more Difference;Mainly using the HDPE pipelines of minor diameter, pipeline construction has a certain amount of earthwork evacuation and backfill to circular saddle weight.Rectangle With good performance, it is adaptable to various operating modes, but correspondingly armored concrete amount increases, and cost is high, uneconomical.
Utility model content
The utility model aims to provide a kind of armored concrete saddle weight for being applied to seabed HDPE pipelines, and it possesses is easy to The characteristics of construction, good stability, reduction quantities.
To achieve the above object, the utility model uses following technical scheme:A kind of seabed HDPE pipeline saddle weights include The top saddle weight and bottom saddle weight being made of armored concrete prefabricated section, the top saddle weight are consolidated with bottom saddle weight Fixed connection, the top saddle weight is trapezoidal hollow shape, and its left and right sides is respectively arranged with boss, and the top saddle weight is left The boss of right both sides is separately provided for the through hole of fixing bolt, and the bottom saddle weight is rectangular hollow shape, it is described under Portion's saddle weight is provided with the groove for fixing bolt.
The saddle weight that the utility model is used is shaped as trapezoidal and rectangle combination:Top saddle weight is trapezoidal hollow shape Shape, bottom saddle weight is rectangular hollow shape.In the form of assembling up and down, two parts are bolted company to the utility model Connect, the top saddle weight and bottom saddle weight both sides are respectively fixedly connected using 1 ~ 4 bolt, top saddle weight and bottom Saddle weight both sides are respectively fixedly connected using 2 bolts.
In order to avoid saddle weight is slided during pipe laying, the bolt power of fixed weight block is sufficiently large, according to Experience, bolt power should be 2~3 times of saddle weight weight.
Consider that pipeline is influenced by temperature, cause and expand with heat and contract with cold, in order to prevent pipeline from causing pipeline due to temperature stress Deformation is destroyed, and bolt is arranged below compensator, to compensate expanding with heat and contract with cold for pipeline, so as to reduce the stress of tube wall and act on Active force on bolt.
The ballast block of material that the utility model is used is armored concrete, in order to meet the anticorrosion requirement of briny environment, Concrete grade be C35 and its more than, thickness of concrete cover is 75mm, and other components such as bolt are processed using galvanizing.
The saddle weight aperture ratio outer diameter tube that the utility model is used is bigger, is easy to set protection bed course-twined on pipeline Around two slat gum bed courses.Top saddle weight and bottom saddle weight two parts all reserve hanging object hole, handling and installation when being easy to construct. In order to limit flexural deformation of the HDPE pipelines in seabed in process of deployment, reduce air and build up the chance to form hole, spacing should As far as possible small, the quality of such balancing weight can be uniformly distributed on pipeline, and the spacing of saddle weight typically takes 2~3m.
Compared to existing technology, the beneficial effect of utility model is:
(1)The overall structure shape matching of saddle weight is reasonable.Optimize the form of fracture of saddle weight, the stability of saddle weight Mainly undertaken by bottom saddle weight rectangular shape, increase the coefficient of friction and contact area of saddle weight and sea bed, while increasing The strong anti-overturning energy of saddle weight.
(2)For the HDPE pipelines of major diameter.Top saddle weight uses trapezoidal shape, can meet force request, saves again About material, reduces financial cost.
(3)Have a wide range of application, it is adaptable to more complicated geological conditions.Particularly in abysmal area, wave force and ocean current power pair The influence of pipeline is smaller, and pipeline can be laid immediately on sea bed, it is not necessary to carries out ditching buried depth treatment, reduces digging up and filling in Amount, saves construction investment.
