Abstract

The invention discloses an assemble rectangular ejecting tube section. Each rectangular ejecting tube section is composed of two or more than two pieces of assemble prefabricated tube sheets, a convenient and fast joint or a step shear key, a pre-buried water stop steel pnd a sealed water stop rubber strip are arranged on each prefabricated tube sheet, quick positioning and connecting fixing are conducted on the splicing surface of each prefabricated tube sheet through the convenient and fast joint or the step shear key, the pre-buried water stop steel plate is arranged on the outer side of the slicing surface of each prefabricated tube sheet for water stopping, the grouting hole is reversed in the inner side of the splicing surface of each prefabricated tube sheet, the sealed water stop rubber strip is reversed at the splicing surface of each prefabricated tube sheet, and a waterproof system is formed jointly by the pre-buried water stop steel plate, the grouting hole and the sealed water stop rubber strip; and an inter-ring pre-buried water stop steel plate and a sealed water stop rubber strip are arranged between tube sections, and sealing is achieved through ejecting feeding pressure for ejecting. In addition, by being combined with use functions, a wing wall and/or a laminated plate is needed to be arranged in each ejecting tube section to form a space stable structure, atemporary supporting function is achieved during assembling, and the functional requirements of the use state are met.

Description

technical field [0001] The invention relates to the related field of parking planning, and more specifically relates to an assembleable rectangular pipe-jacking joint. Background technique [0002] With the advancement of urbanization, the ground buildings in various cities are gradually increasing, especially in the core areas of most cities, the density of ground buildings is increasing. Such dense ground buildings also bring more difficulties to the construction of underground structures, and the frequent excavation of urban roads also brings a lot of inconvenience to the lives of citizens. Pipe jacking technology is a non-excavation construction method, which is a construction technology for pipeline burial without excavation or less excavation, and is generally used in municipal engineering. Since this excavation method requires no or less excavation, it has little impact on urban construction during construction, does not block road traffic, allows vehicles to pass no...
