Concrete pouring height real-time monitoring method and system

Abstract

The invention discloses a concrete pouring height real-time monitoring method. The method comprises the steps of: laying temperature sensing optical fibers in a pouring area; performing real-time monitoring of the temperature of the pouring area through the temperature sensing optical fibers; when a difference value between a temperature value t1 acquired by a certain temperature detection point on a horizontal section and a temperature value t2 acquired by the point before a preset time interval T exceeds a preset difference value [Delta]t, recording the point as an abnormal fluctuation point; and when the number of the abnormal fluctuation points on the horizontal section exceeds a preset value x, judging that the concrete covers the horizontal section. The invention further discloses aconcrete pouring height real-time monitoring system. The system comprises temperature sensing optical fibers, an optical fiber sensing and detection unit, a real-time data analyzing and processing unit. By adopting the technical scheme mentioned above, the liquid level height of the whole concrete pouring area can be monitored in real time, the pouring liquid level height of the area can be monitored when the optical fibers are distributed in a certain area, and the concrete pouring height real-time monitoring method and system are particularly suitable for large concrete structures.

Description

technical field [0001] The invention relates to a method and system for real-time monitoring of concrete pouring height, belonging to the technical field of concrete construction. Background technique [0002] In the process of medium and large concrete construction, the method of segmented and layered pouring is generally used to break the whole into parts, improve work efficiency and ensure project quality. In the concrete construction specification, there are strict requirements for the segmented layered pouring method: (1) The layered height is 1.25 times the length of the inserted vibrator, and the maximum is not more than 500mm; (2) The pouring of concrete should be carried out continuously, If the interval is necessary, the interval should be shortened as much as possible, and the concrete of the second layer should be poured before the initial setting of the concrete of the front layer, and it should be treated as a construction joint if it exceeds 2 hours; (3) When ...

Problems solved by technology

This device has the following disadvantages: it is only suitable for the specific application scenario of cast-in-place piles, and it is not practical for large-area concrete pouring; it is troublesome to operate, and the hammer needs to be placed again every time the pouring height is tested, and the readings and calculation heights must be manually recorded

However, this method does not provide how to get the pouring height
