Abstract

The invention provides an adjustable supporting guide rail for use in the construction process of a top pipe. The adjustable supporting guide rail comprises two rails and support legs, wherein the tworails are arranged in parallel and are connected through cross braces, and the lengths of the cross braces can be adjusted; and a plurality of the support legs are correspondingly arranged on the tworails, one ends of the support legs are connected with the rails, the other ends of the support legs are supported on the ground, and the heights of the support legs can be adjusted. By adjusting thelengths of the cross braces, the distance between the two rails is changed, so that the adjustable supporting guide rail can meet the support requirements on pipe joints with different diameters; andby adjusting the heights of the support legs, the heights of the rails are changed, so that the adjustable supporting guide rail can meet the adjustment requirements when the outer diameters of the pipe joints of different top pipe sections are different and the distances from the design heights of the pipe joints to the bottom of a top pipe working well are not uniform, the real-time adjustmentcan be realized according to the working site, and the adjustable supporting guide rail can meet the demands under different working conditions.

Description

technical field [0001] The invention relates to the technical field of tunnel construction, in particular to an adjustable support guide rail used in the construction process of pipe jacking. Background technique [0002] During the pipe jacking construction process, the guide rails supporting the pipe joints are fixed on the design work surface by welding and concrete pouring, and the pipe joints are placed on the guide rails before jacking. Before the jacking pipe enters the soil, the guide rail undertakes the guiding function to ensure that the pipe joint advances according to the design elevation and direction. [0003] In the actual construction, it was found that in the same project, due to the different outer diameters of the pipe joints in each section of the pipe jacking section, and the distance between the design elevation of the pipe joints and the bottom of the pipe jacking well is not uniform, if the distance is too large, welded steel is required for support ...
