Embodiment Construction

[0031] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0032] Such as Figure 1-Figure 2 As shown, they are respectively the side view of the embodiment of the trenchless correction device for pipeline centerline deviation of the present invention and the rear view of the front casing. It should be noted, figure 1 Shown is the correction processing equipment for the high centerline of the pipeline, and the processing equipment with the low centerline, left, and right is similar to the structure shown in the figure, and will not be repeated here. The trenchless correction equipment for pipeline centerline deviation of this embodiment includes a front housing 11, a rear housing 12, and a lifting adjustment device 13, and the front housing 11 and the rear housing 12 are both cylindrical. Where...

Abstract

The invention provides a non-excavation correction method and apparatus of pipeline center line deviation after pipe-jacking construction. The apparatus comprises a front case, a back case and an elevation adjusting apparatus. Both the front cast and the back case are cylindrical objects. The front part of the front case is connected with a deviation pipeline to be corrected, and a supporting opening is made in the back part of the front case. The front part of the back case is provided with a fixing stand that protrudes out from the end face, the back part of the back case is connected with the to-be-corrected pipeline that is to be connected, and the back case is connected with the front cast by enabling the fixing stand stretch into the supporting opening. The bottom of the elevation adjusting apparatus is placed in the front cast, and the top is connected with the fixing stand that stretches into the supporting opening. The invention further provides a pipe-jacking construction method applied to the center line deviation correction apparatus. The apparatus and method provided in the above scheme can solve the deviation problem of a pipeline center line relative to the designed center line, and the scheme has the advantages of simple mechanical design, low cost and less resource consumption.

Description

Technical field [0001] The invention relates to the technical field of pipe jacking construction of municipal engineering, and in particular to a device for correcting centerline deviations after pipe jacking construction and a method for applying the correcting device. Background technique [0002] Due to the uneven soil quality of the pipe during pipe jacking construction, the soil pressure acting on the surrounding wall of the pipe is not balanced, the resistance of the pipe head is uneven, the friction between the pipe wall and the soil is uneven, the small error of the jack point, tool pipe or blade foot Various factors such as processing errors, pipe joint dimensions, equipment installation accuracy, and pipe jacking construction errors generated during pipe jacking operation will cause deviations in pipe jacking. Therefore, pipe jacking construction must be based on diligent measurement, diligence, The principle of diligence and diligent correction, when deviations are fou...
