Embodiment Construction

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. 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] Such as Figure 1-5 As shown, a measurement method for measuring the manufacturing accuracy of a curved pipe curtain includes the following steps: S1: Divide the curved pipe curtain into X-section pipe joints, and then measure the cross-section roundness, curvature measurement and length of the X-section pipe joints Measurement. The curved pipe curtain is a ring-shaped steel pipe, and each section of the X-section pipe joint is an arc-shaped steel pipe...

Abstract

The invention discloses a measuring method for measuring manufacturing precision of a curve pipe curtain, and solves the problems that curve pipe curtain measurement is not easy and convenient and themeasurement data precision is not high and the like in the prior art. The measuring method comprises the following steps: step S1, dividing the curve pipe curtain into X sections of pipe joints, andperforming section roundness measurement, curvature measurement and length measurement on the X sections of pipe joints. The measuring method for measuring the manufacturing precision of the curve pipe curtain provided by the invention effectively measures the roundness of each section of the curve pipe curtain, the curvature of the curve pipe curtain and the length of the curve pipe curtain. Theaccuracy of a manufacturing method can be verified, a manufacturer can be facilitated to improve the manufacturing process, and the construction precision is guaranteed, so that the construction accuracy and safety are guaranteed.

Description

technical field [0001] The invention relates to the technical field of tunnel construction measurement methods, in particular to a measurement method for measuring the manufacturing accuracy of curved pipe screens. Background technique [0002] The pipe curtain method is developed from the pipe shed technology in the mining method, and refers to a non-excavation construction method in which steel pipes are used to form advance support. The curve pipe curtain method generally uses a small pipe jacking machine to jack into the soil along a certain curve to form an advance support, and then excavates the main structure of the construction or uses a box culvert jacking scheme to carry out construction. A new type of underground excavation method construction technology , the pipe curtain is generally constructed by a small pipe jacking machine, and the diameter of the steel pipe used is generally 600mm-1600mm. Currently, the drilling method used for freezing or underground excav...
