Description
(54) ОПОРА ТРУБОПРОВОДА(54) PIPING SUPPORT
1one
Изобретение относитс к строительству и может быть исподьзовано при строительстве трубопровода в зонах активной деформации грунта, в частности на подрабатываемых территори х.The invention relates to construction and can be used in the construction of a pipeline in areas of active soil deformation, in particular in the undermined territories.
Известна опора трубопровода, включающа наружный кожух с опорами внутри, выполненными в виде спаренных цилиндрических роликов, установленных на кронштейнах под пр мым углом друг к другу между основанием и трубопроводом. Ось одного ролика закреплена на трубопроводе, а ось второго - на наружном кожухе, при этом пары роликов установлены диаметрально противоположно друг другу относительно оси трубопровода 1 .A pipeline support is known, which includes an outer casing with inside supports made in the form of paired cylindrical rollers mounted on brackets at a right angle to each other between the base and the pipeline. The axis of one roller is fixed on the pipeline, and the axis of the second - on the outer casing, while the pairs of rollers are set diametrically opposite to each other relative to the axis of the pipeline 1.
Данна конструкци позвол ет перемещатьс трубопроводу в осевом направлении и в направлении перпендикул рном оси трубопровода, однако она не позвол ет компенсировать осадки грунта под основанием.This design allows the pipeline to move in the axial direction and in the direction perpendicular to the axis of the pipeline, but it does not allow to compensate for the precipitation of the soil under the base.
Наиболее близкой к изобретению вл етс опора трубопровода, состо ща из наружного кожуха, в котором размещены опоры, выполненные в виде гибких оболочек , заполненных газом, на которые уложен трубопровод 2.Closest to the invention is a pipeline support consisting of an outer casing, in which supports are provided, made in the form of flexible shells filled with gas, on which pipeline 2 is laid.
Недостатком этой опоры вл етс поломка трубопровода при деформации грунта на подработанных территори х.The disadvantage of this support is the failure of the pipeline during the deformation of the soil in the underworked territories.
Цель изобретени - предохранение трубопровода от поломки в случае, значительных деформаций грунта.The purpose of the invention is to protect the pipeline from breakage in the event of significant soil deformations.
Указанна цель достигаетс тем, что полости гибких оболочек сообщены между собой .This goal is achieved by the fact that the cavities of flexible shells communicate with each other.
На фиг. 1 изображена предлагаема опора трубопровода, исходное положение; на FIG. 1 shows the proposed pipeline support, the initial position; on
10 фиг. 2 - разрез А-А на фиг. 1; на фиг. 3 - опора трубопровода после деформации грунта основани .10 of FIG. 2 shows section A-A in FIG. one; in fig. 3 - pipeline support after base deformation.
Опора трубопровода состоит из наружного кожуха 1, помещенных внутри его опороболочек 2 с перемычками 3, по которым The pipeline support consists of an outer casing 1, placed inside its support frames 2 with bridges 3, through which
15 уложен трубопровод 4. .15 laid pipeline 4..
Опора трубопровода работает следующим , образом.The pipeline support works as follows.
В исходном положении трубопровод ле20 жит внутри кожуха 1 на гибких оболочках 2, нагрузка на которые равномерна. В случае осадки грунта основани наружный кожух 1 деформируетс вплоть до разрушени .In the initial position, the pipeline lies inside the casing 1 on the flexible shells 2, the load on which is uniform. In the event of a precipitation of the base soil, the outer casing 1 is deformed until destruction.
Нагрузка на опоры 2 измен етс , и при этом возрастает, давление на опоры 2, наход щиес на недеформированном участке, а на опоры 2, осевшие вместе с наружным кожухом 1, соответственно уменьшаютс , и вследствие этого по св зуюш,им оболочки перемычкам 3 происходит перераспределение рабочего тела до тех пор, пока нагрузки на каждую из оболочек не уравн ютс . В результате деформации грунта основани и даже повреждение наружного кожуха не вызовут напр жений в трубопроводе 4 и сохранитс его эксплуатационное состо ние. Технико-экономическа эффективность заключаетс в ликвидации аварийного состо ни трубопроводов, наход щихс в зонах осадки грунта, и позволит сократить затраты на ремонтные работы по этому виду разрушений.The load on the supports 2 varies, and at the same time, the pressure on the supports 2 located in the undeformed area increases, and the supports 2 deposited together with the outer casing 1 decrease accordingly, and as a result, the shells of bridges 3 are connected to them redistributing the working fluid until the loads on each of the shells are equalized. As a result of the deformation of the soil of the base and even damage to the outer casing, it will not cause stresses in the pipeline 4 and its operational state will remain. Technical and economic efficiency consists in the elimination of the emergency condition of pipelines located in areas of soil sediment, and will reduce the cost of repair work on this type of damage.
