Embodiment Construction

[0067] This method for evaluating the risk level of new construction crossing existing road facilities includes the following steps.

[0068] Step 1: Survey the pipeline 2 under the existing road facilities 1 and obtain the survey results; the survey content includes the type of pipeline and the diameter of the pipeline.

[0069] Step 2: Divide the existing road facilities 1 within the affected area of ​​the crossing project 3 into three grades: particularly important, important and generally important according to their importance. The method of classification is as follows:

[0070] When the existing road facilities located within the impact area of ​​the crossing project 3 are urban expressways and their affiliated bridges and tunnel facilities or expressways and their affiliated bridges and tunnel facilities, the importance level is particularly important;

[0071] When the existing road facilities located within the affected area of ​​the crossing project 3 are urban trunk roads a...

Abstract

A method of evaluating the risk grade of a new project crossing the existing road facility comprises the steps of firstly surveying a pipeline under the existing road facility, and obtaining a surveying result; 2, dividing the existing road facilities in the range of the influence area of the crossing project into three grades according to the importance of the existing road facilities; step 3, correcting the importance classification level of the existing road facility; 4, determining a construction method of a crossing project; 5, surveying the position relation between the crossing projectand the existing road facility and the distance between the crossing project and the existing road facility; 6, obtaining the approach relationship level of the crossing project and the existing roadfacility; 7, preliminarily evaluating the risk level of the crossing project; 8, correcting the risk level of the crossing project, and finally obtaining the risk level of the crossing project, so that the technical problems that a traditional risk grade division method is large in dependence on subjective judgment and inaccurate in division result are solved.

Description

Technical field [0001] The invention relates to the field of road engineering, in particular to a method for evaluating the risk level of a newly built project crossing existing road facilities. Background technique [0002] A crossing project refers to a new or renovated or expanded project that uses up-crossing, down-crossing, parallel, up-spanning, or connection to traverse existing road facilities and may affect its structure or operation. According to different crossing angles, crossing projects can generally be divided into orthogonal (α=90°) and oblique crossing (15° <α <90°) and parallel (α≤15°) three ways. Existing road facilities refer to roads and their ancillary facilities that have been constructed or put into use, mainly including municipal roads, municipal bridges, urban tunnels, underground passages, highways, highway bridges, highway tunnels, pedestrian bridges, and ancillary facilities of the above structures. [0003] When the project crosses road faciliti...
