Abstract
Description
Technical Field
[0001] The utility model relates to the field of cable laying, in particular to a prefabricated cable pipe corner module. Background Art
[0002] During the cable conduit laying process, corner wells need to be set up at the turning points. Corner wells are large in size, require a large amount of work, and require excavation of a large working space. In crowded underground pipeline scenes such as cities and industrial parks, there is no space for corner wells or no construction conditions. At the same time, corner wells are usually constructed by on-site casting. The construction process includes: steel sheet pile support, foundation pit excavation, foundation treatment, formwork support, steel bar tying, concrete pouring, concrete maintenance, formwork removal, backfilling and sealing, etc. On-site operations require a large amount of labor, a long construction period, cumbersome acceptance of hidden projects, and high environmental pollution. Especially in urban construction operations, urban roads are bound to be blocked, which brings inconvenience and impact to citizens' lives and production. The existing operation form has gradually fallen behind the concept of modern urban development and construction. Utility Model Content
