Embodiment 1

[0018] Such as figure 1 , figure 2 As shown, the automatic measurement method for pipe jacking is as follows: through manual input of zero position data, design midline data and on-site measured data, it is automatically imported into the measurement database, thereby calculating various parameters such as the real-time attitude of the pipe jacking machine, the design axis deviation, etc., so as to guide construction.

[0019] The specific method steps of the above-mentioned automatic pipe jacking measurement method are as follows:

[0020] a. System assembly and commissioning, installation of reference prisms, connecting cables, total stations, industrial computers and other corresponding equipment, commissioning of communication and other preparations are completed, see attached figure 1 ;

[0021] b. Input relevant parameters, and enter various index parameters such as design midline data, zero position data, and preset deviation values ​​into the computer;

[0022] c....

Embodiment 2

[0025] Take the Kunming tail water discharge pipe jacking project as an example. Kunming Tail Water Outward Drainage Pipe Jacking Project is one of Kunming Dianchi Sewage Treatment Projects. There are 11 working wells divided into 10 sections of jacking lines on the whole line, and the longest top section 9# well-pump station# well top section has a total length of 1.2 kilometers , belongs to the ultra-long-distance pipe jacking construction. Since the pipe joints follow up with the extension of the top section during the pipe jacking construction, it belongs to dynamic measurement, and must be jacked in one direction to the exit shaft. The accuracy requirements for tunnel measurement higher. There is 2 hours of free time for real-time measurement of each pipe section from transfer, installation to top opening. After the pipe jacking tunnel has a long jacking distance, the traditional method cannot guarantee that the machine can be completed within a limited time without makin...

Abstract

The invention relates to the field of construction and tunnel measurement technique, and particularly relates to an automatic measurement and guidance system and an automatic measurement and guidance method related to pipe pushing construction. The automatic measurement and guidance system comprises a full-automatic total station instrument, a wireless radio station, remote control equipment, a computer, an application tool, a pipe pusher, an MTG-T optical target, a prism, a sensor and a control cabinet, wherein the MTG-T optical target is arranged on the head of the pipe pusher; during the pipe pushing process, the whole pipe moves forwards, a travel sensor is arranged on the top of a tunnel portal, a forward vision prism and a reference prism are arranged on the upper wall of an inner cavity of a second tunnel pipe joint of the pipe, and can continuously move according to the pipe joint of the pipe, a back vision prism is arranged on the upper wall of an inner cavity of previous pipe joint of the tail end pipe joint of the pipe, and the total station instrument is arranged at the central position of an inner cavity of the front end pipe joint of the pipe. Compared with the prior art, the automatic measurement and guidance system has the advantages of alleviating the labor intensity of workers, improving the working efficiency and the construction precision of the pipe pushing construction, as well as analyzing and treating, timely controlling and timely making a decision through real-time data, so that the through accuracy between two wells is guaranteed.

Description

[technical field] [0001] The invention relates to the technical field of construction and tunnel measurement, in particular to an automatic measurement and guidance system and method related to pipe jacking construction. [Background technique] [0002] In pipe jacking and tunnel construction, in order to ensure the correct penetration of various excavation surfaces and meet the design requirements, it is necessary to measure the axis and elevation of the tunneling direction in real time along with the tunnel construction. This measurement is called tunnel surveying. At present, the construction measurement methods of underground tunnel projects include the traditional wire method suitable for underground excavation tunnels; the shield automatic measurement and guidance system suitable for subway shield construction; all of the above can be used as control points in the formed tunnel as the tunnel extends. To carry out transmission, so as to ensure the accuracy of tunnel pene...
