(54) СПОСОБ АВТОМАТИЧЕСКОГО КОНТРОЛЯ КАЧЕСТВА ВИБРОУПЛОТНЕНИЯ ЖЕЛЕЗОБЕТОННЫХ ЭЛЕМЕНТОВ(54) METHOD FOR AUTOMATIC CONTROL OF QUALITY VIBRATION OF REINFORCED CONCRETE ELEMENTS

1one

Изобретение относитс  к области контрол  качества сборных железобетонных элементов при их формовании и может быть использовано при изготовлении элементов (блоков или тюбингов) тоннельной обделки.The invention relates to the field of quality control of precast concrete elements during their molding and can be used in the manufacture of elements (blocks or tubings) of tunnel lining.

Известны способы автоматического контрол  качества виброуплотнени  железобетонных элементов, например, тюбингов тоннельной обделки, при их изготовлении, включающие установку вибродатчиков, измерение их сигналов и фиксацию момента стабилизации свойств уложенной в форму на вибростенде бетонной смеси.There are known methods for automatically controlling the quality of vibro-compaction of reinforced concrete elements, for example, tunnel lining tubing, during their manufacture, including the installation of vibration sensors, measuring their signals and fixing the moment of stabilization of the properties of a concrete mixture laid in a form on a vibrostand.

Недостатком известных способов  вл етс  необходимость перестановки вибродатчиков с их тарировкой на каждый изготавливаемый элемент, при этом вибродатчики устанавливаютс  на бетонную смесь, что затруднено при наличии пригруза.A disadvantage of the known methods is the necessity of rearranging the vibration sensors with their calibration for each manufactured element, while the vibration sensors are mounted on a concrete mix, which is difficult in the presence of a prigruz.

Целью изобретени   вл етс  обеспечение непрерывного контрол  и повышение точности измерений.The aim of the invention is to provide continuous monitoring and increase measurement accuracy.

Достигаетс  это тем, что фиксацию момента стабилизации свойств уложенной в форму бетонной смеси производ т путем измерени  отношени  сигналов датчиков, установленных на детал х формующей установки, например вибростоле и пригрузе.This is achieved by fixing the moment of stabilization of the properties of the concrete mixture laid in the form produced by measuring the ratio of the sensor signals installed on the details of the forming unit, such as a vibrating table and a load.

Предложенный способ автоматического контрол  качества виброуплотнени  железобетонных деталей заключаетс  в том, ч го вибродатчики устанавливают не на изготавливаемое изделие, а на детали формующей установки и измер ют параметры колебаний этих элементов, например вибростола и пригруза . Сигналы датчиков измер ют сравнивающим прибором, например логометром. Стабилизаци  показаний прибора свидетельствует о достижении максимальной степени уплотнени .The proposed method of automatically controlling the quality of vibration compaction of reinforced concrete parts consists in the fact that vibration sensors are not installed on the manufactured product, but on the details of the forming unit and the vibration parameters of these elements, for example, the vibrating table and the weights, are measured. Sensor signals are measured by a comparative instrument, such as a logometer. Stabilization of instrument readings indicates that the maximum degree of compaction has been reached.
