[0003] The conventional pipeline survey method does not work well in the utility tunnel, mainly because: 1. Introducing the ground control point into the comprehensive utility tunnel has complicated procedures, poor practicability, and low accuracy; It is difficult to measure the pipe points; 3. It is difficult to ensure that the measurement results are parallel to the pipe gallery, and the relative position is inaccurate; 4. The cost is high, and it is time-consuming and laborious to lay out control points and collect data in the field; Management, maintenance and protection, and the pipelines inside the comprehensive utility gallery have no risk of being damaged, so the relative position relationship with the comprehensive utility gallery is more important than the absolute position; 6. The entrance and exit of the comprehensive utility gallery are generally vertical shafts, which are dangerous up and down. Measuring instruments (total stations, levels) are bulky and expensive, and are prone to collisions, resulting in losses
7. There are many ancillary facilities for pipelines in the comprehensive pipeline gallery, and generally protruding pipeline parts, it is difficult to measure to the exact position with conventional measuring tools
[0004] Since the conventional pipeline survey method is not suitable for the survey of pipelines in the comprehensive pipeline gallery, in order to obtain accurate and detailed pipeline data, it is necessary to formulate a practical implementation plan and cooperate with appropriate measurement tools to ensure the smooth implementation of the project

Embodiment approach
[0023] In the following, a detailed introduction is made to the pipeline survey measurement tool and method in the integrated pipe gallery of the present invention with reference to the accompanying drawings and embodiments.
[0024] like figure 1 and figure 2 As shown, the pipeline survey measurement tool in the integrated pipe gallery of the present invention includes two parts: a spotting ruler and a measuring ruler. Among them: the cast point ruler is composed of a cross ruler with a scale 1, a plumb 3 and a wire rope 2. The cross ruler 1 is made of two 1-meter-long square aluminum alloys, both with scales and can be rotated freely. According to the roundness of the comprehensive pipe gallery access hole, the cross ruler is rotated to demarcate the center of the comprehensive pipe gallery access hole. Position; put one end of the wire rope 2 through the center of the intersection of the cross ruler and fix it, and use the weight of the plumb 3 to cast the center of the ...

The invention relates to the technical field of general investigation of pipelines in a comprehensive pipe gallery, in particular to a measuring tool and a measuring method for general investigation of the pipelines in the comprehensive pipe gallery. The measuring tool comprises a plumbing ruler and a measuring ruler, wherein the plumbing ruler is composed of a cross-shaped ruler provided with graduations, a plumb and a steel wire rope; one end of the steel wire rope passes through the center of an intersection of the cross-shaped ruler and is fixed with the cross-shaped ruler, and the other end is connected with the plumb; the measuring ruler is composed of a fixed ruler, a sliding ruler and a mark post provided with graduations; the mark post is vertically fixed on the fixed ruler; and the sliding ruler sleeves the mark post, and can slide on the mark post. The measuring tool and the measuring method for general investigation of the pipeline in the comprehensive pipe gallery utilize the known comprehensive pipe gallery box body data, measure various kinds of unknown pipeline data in the comprehensive pipe gallery, ensure the correctness of relative positions of the various pipelines, improve the working efficiency and realize the consistency between the comprehensive pipe gallery box body data and the pipeline data in the comprehensive pipe gallery.
Description
technical field [0001] The invention relates to the technical field of pipeline general survey in a comprehensive pipe gallery, in particular to a measuring tool and a method for the general survey of pipelines in a comprehensive pipe gallery. Background technique [0002] Comprehensive pipe gallery is an important part of urban infrastructure, in order to better grasp the distribution and direction of pipelines in comprehensive pipe gallery, ensure the integrity of underground pipe network data information and 3D model, and provide reliable information for planning and construction. Data support, it is necessary to carry out a comprehensive census of the pipelines in the comprehensive pipeline gallery on the basis of the conventional pipeline census. [0003] The conventional pipeline census method is not effective in the pipe gallery, mainly because: 1. Introducing the ground control point into the comprehensive pipe gallery, the process is complicated, the practicability ...
