Description

Technical Field

[0001] The present application belongs to the technical field of riverbed trench support, and specifically relates to a riverbed pipeline trench support structure. Background Art

[0002] The riverbed pipeline trench is a specific space excavated at the bottom of rivers, lakes and other water bodies for installing and laying pipelines. Due to the special environment of these places, the excavation of riverbed pipeline trenches and the installation of pipelines face many challenges, among which stability and safety are particularly important. In order to ensure the smooth progress of the construction process, it is very necessary to support the trench. Such a support structure can ensure the safety and smooth progress of the construction and protect the pipeline from external damage;

[0003] In trench support, support structures are usually divided into temporary and permanent supports. Temporary supports are used during construction to prevent soil collapse or deformation and ensure construction safety. Common temporary supports include steel sheet piles. These support structures can be removed or reused for other projects after construction is completed.

[0004] Permanent support is used to maintain the stability of trenches or excavated areas over a long period of time and ensure the long-term stability of foundations or soil. In riverbed environments, permanent support usually uses concrete retaining walls and reinforced concrete slabs. These structures not only provide support during construction, but also provide protection for pipelines in the long term.

[0005] However, most of the current concrete retaining walls and reinforced concrete slabs adopt an integral structure. This design has inconveniences in the splicing and installation process, making rapid installation and disassembly difficult. In addition, these integral structures are less effective in preventing water scouring and soil sedimentation. For this reason, a riverbed pipeline trench support structure is provided.
