Embodiment Construction
[0020] A clear and complete description will be made below in conjunction with technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0021] The jacking construction method of the multi-line parallel large-diameter mud-water balance pipeline with thin covering soil and small clear distance includes the following steps:
[0022] (1) Preparation before jacking:
[0023] During the construction, construct the reaction wall according to the specifications and materials determined by the design, install the reaction dispersing frame, and install the positioning track in the working well according to the actual three-dimensional space position, as the i...

The invention discloses a thin-earthing small-clear-distance multi-line parallel large-diameter slurry balance pipeline jacking construction method, which comprises the following steps of: in a pipe jacking process, timely mastering a pipeline jacking construction axis track, and timely taking corresponding technical measures to adjust the posture of a pipe joint when the jacking axis of a front section of the pipe joint is deviated, so that the pipe joint is accurately jacked. And the jacking mechanism returns to the original design position and then continues to be jacked. And finally, combining engineering monitoring data, drawing a completion curve, and verifying and analyzing a control implementation effect of the jacking construction axis of the small-clear-distance long-distance multi-line parallel pipeline and the like, so as to form a set of complete control method for the jacking construction axis of the small-clear-distance multi-line parallel earthing thickness dramatic change large-diameter slurry balance pipeline.
Description
technical field [0001] The invention relates to the technical field of pipeline jacking construction, in particular to a construction method for jacking a thin-covered soil, small clear distance, multi-line parallel large-diameter mud-water balanced pipeline. Background technique [0002] In recent years, because the construction of pipe jacking has little impact on urban traffic and residents' life, and the construction process has the advantages of less soil excavation and less damage to existing pipelines and buildings, pipe jacking has been widely used to solve urban internal problems. drainage and waterlogging issues. The theory of large-diameter and long-distance mud-water balance pipe jacking construction method is to fill the mud water tank of the roadheader with mud water containing a certain amount of clay and with a certain relative density, and apply a certain pressure to it to balance the groundwater pressure and earth pressure. , according to this theory, mud ...
