Abstract
Изобретение относитс к строительству и может быть использовано при сооружении магистральных трубопроводов в просадочных грунтах и в зонах с повышенной сейсмичностью. Цель изобретени - повышение эксплуатационной надежности трубопровода путем создани дополнительных опорных площадок и укладки трубопровода в виде пространственной ступенчатой спирали, поглащающей сейсмические колебани . В боковых стенках траншеи 1 создают продольные полки 3, 4, а трубопровод 5 укладывают змейкой. При этом горизонтальные звень укладывают на полки 3, 4 и дно 2 траншеи 1 и соедин ют горизонтальные звень наклонными.The invention relates to the construction and can be used in the construction of trunk pipelines in subsiding soils and in areas with high seismicity. The purpose of the invention is to increase the operational reliability of the pipeline by creating additional support sites and laying the pipeline in the form of a spatial stepped helix absorbing seismic vibrations. In the side walls of the trench 1 create a longitudinal shelves 3, 4, and the pipe 5 is laid snake. In this case, the horizontal links are laid on the shelves 3, 4 and the bottom 2 of the trench 1 and the horizontal links are joined by inclined ones.

Изобретение относитс к стройтель- ству и может быть использовано при сооружении ма гистральных трубопроводов в просадочных грунтах и в зонах с повышенной сейсмичностью.The invention relates to construction and can be used in the construction of trunk pipelines in subsiding soils and in areas with high seismicity.
Цель изобретени - повышение эксплуатационной надежности трубопровода путем создани дополнительных опорных площадок и укладки трубопро- Q вода в виде пррстранственной ступенчатой спирали, поглощающей сейсмические колебани .The purpose of the invention is to increase the operational reliability of the pipeline by creating additional support sites and laying the pipeline Q in the form of a space-stepped spiral that absorbs seismic vibrations.
На фиг. 1 изображена схематически транше с трубопроводом,смонти- 5 рованным ступенчатой спиралью, аксонометри ; на фиг. 2 - разрез А-А на иг. 1.FIG. 1 shows a schematic of a trench with a pipeline mounted by a stepped helix, axonometrics; in fig. 2 - section AA one.
Отрывают траншею 1 с дном 2 и расир ют ее с образоваштем полок 3 и 4, 20 после чего укладывают трубопровод 5, который образует ступенчатую спираль, в плане уложенную змейкой и послеовательно опирающуюс в местах поворота последовательно на полки 3 и 4, 25 но 2.The trench 1 is torn off with the bottom 2 and is expanded with the formation of shelves 3 and 4, 20, and then the pipeline 5 is laid, which forms a stepped spiral, laid down in a snake pattern and subsequently resting in places of rotation successively on shelves 3 and 4, 25 but 2.
Монтаж трубопровода осуществл ют следующим образом.The installation of the pipeline is carried out as follows.
Укладывают трубу 6 концами на полки 3 и 4, а трубу 7 - на полку 4 и ЗО но 2, состыковывают на полке 3 торцы труб 6 и 7. Трубу 8 укладывают на дно 2 траншеи и стыкуют с трубойThe pipe is laid with 6 ends on shelves 3 and 4, and pipe 7 is placed on shelf 4 and 30 but 2, 3 ends of pipes 6 and 7 are joined on the shelf. Pipe 8 is placed on the bottom 2 of the trench and dock with the pipe
Фиг.11
7. Трубу 9 стыкуют концом с трубой 8 на дне 2 траншеи, а другим концом укладывают на полку 3 и т.д.7. Pipe 9 is joined by an end with a pipe 8 at the bottom 2 of the trench, and the other end is laid on shelf 3, etc.
После укладки и монтажа трубопровода провод т засыпку траншеи.After laying and installing the pipeline, the trench is filled.
Увеличение надежности трубопро- вода обеспечивает сокращение трудовых и материальных затрат аварийных ремонтов трубопровода, увеличение производительности предпри тий-потребителей , например воды, нефти, газа и т.п. сырь , а также снижение потерь сырь , неизбежных при авари х.Increasing the reliability of the pipeline ensures a reduction in labor and material costs of emergency repairs of the pipeline, and an increase in the productivity of enterprises-consumers, such as water, oil, gas, etc. raw materials, as well as reducing the loss of raw materials inevitable in case of accidents.
