Pipeline protection structure for resisting sea wave erosion

Abstract

The invention discloses a pipeline protection structure for resisting sea wave erosion, which comprises a foundation, a pipeline and a protection layer, the pipeline is laid on the foundation, the pipeline at least comprises an exposed section exposed out of the foundation, and the protection layer covers the exposed section. The protective layer at least comprises a geotechnical cloth layer covering the exposed section and a sand retaining layer covering the geotechnical cloth layer; sea wave erosion is resisted, the pipeline is prevented from being damaged, and the effect of effectively protecting the pipeline is achieved.

Description

technical field [0001] The invention relates to the field of pipeline protection in sea areas, in particular to a pipeline protection structure for resisting sea wave erosion. Background technique [0002] At present, many large-scale industrial enterprises (such as iron and steel enterprises) are built in coastal areas in order to facilitate logistics and shipping; industrial enterprises need water, and there may be a section of water diversion pipeline and final wastewater discharge pipeline in the factory area that needs to cross the beach section outside the factory. Laying along the coast; if the coast is eroded, due to seawater erosion and severe wave erosion, the absolute elevation of the beach will drop after a period of time, resulting in exposed, worn, and damaged pipelines; the protection of such pipelines is generally designed according to Set up a cladding structure in Figure 4.6.3 of the National Standard for Water Supply and Drainage GB50268-2008, and then cov...

[0002] At present, many large-scale industrial enterprises (such as iron and steel enterprises) are built in coastal areas in order to facilitate logistics and shipping; industrial enterprises need water, and there may be a section of water diversion pipeline and final wastewater discharge pipeline in the factory area that needs to cross the beach section outside the factory. Laying along the coast; if the coast is eroded, due to seawater erosion and severe wave erosion, the absolute elevation of the beach will drop after a period of time, resulting in exposed, worn, and damaged pipelines; the protection of such pipelines is generally designed according to Set up a cladding structure in Figure 4.6.3 of the National Standard for Water Supply and Drainage GB50268-2008, and then cover it with counterweights or twisted king blocks for compaction; combined with the investigation of the implemented projects, this conventional practice cannot effectively protect the pipeline; the tide is low The erosion during the time will hollow out the lower part of the gravel, and then the counterweight or twisted king block will wear the pipeline under the washing of the waves, causing the pipeline to leak
