Embodiment

[0044] A rapid detection and evaluation method for the passability of heavy equipment of medium and small-span concrete bridges is characterized in that it includes the following steps:

[0045] (1) Obtain bridge design information required for evaluation

[0046]Query bridge design data to obtain bridge information. For bridges to be evaluated with serious lack of design data, it is necessary to implement rapid non-destructive testing steps to obtain information such as bridge appearance, geometric dimensions, and physical parameters, such as the structural type, cross-sectional form, and Calculate spans, support types, etc., and check concrete properties and reinforcement. Simultaneously use the standard inspection vehicle load to carry out the on-site static load test on the bridge to be evaluated, and quickly measure the deflection of the bridge;

[0047] The steps of rapid non-destructive testing in step (1) include: bridge appearance and geometric dimension testing, con...

Abstract

The invention relates to a method for quickly detecting and assessing heavy equipment passing ability of a small-and-medium span concrete bridge. Deflection span ratio serves as a quick detecting and assessing index of the bridge, field detecting work contents are decreased, assessment working process of the bridge is simplified, the detection and assessment time is effectively shortened, and whether the small-and-medium span concrete bridge meets the requirement for the heavy equipment passing ability or not can be quickly and accurately assessed. By means of the method and under the condition that bridge design and maintenance materials are seriously lacked, the detection and assessment time of the single small-and-medium span concrete bridge is shortened to less than 6 hours from existing 3-7 days.

Description

technical field [0001] The invention relates to a bridge detection and evaluation technology, in particular to a rapid detection and evaluation method for the passability of heavy equipment of medium and small-span concrete bridges. Background technique [0002] With the expansion of our army's missions, road maneuvers of military heavy equipment show a trend of increasing frequency and scope. The problem of the passage of military heavy equipment on small and medium-span concrete bridges often becomes a bottleneck restricting the choice of maneuvering paths for troops. [0003] At present, the existing bridge detection and evaluation methods generally have shortcomings such as many on-site detection contents, long detection and evaluation time, cumbersome data processing, and poor operability, which cannot meet the requirements of rapid detection and evaluation of the passage of heavy equipment in military transportation support. Taking the most commonly used load test meth...
