Background of the Invention
Prefabricated beam body construction is widely used in high-speed railways, highways and municipal bridges, and with the promotion and development of prefabricated bridges, the proportion of prefabricated beam bodies is increasing. In order to improve the construction efficiency and quality of the prefabricated beam body, a large number of prefabricated beam body formworks adopt hydraulic formworks. With the requirement of accelerating the intelligent and automated construction market, the manually controlled hydraulic formwork has gradually developed into the hydraulic formwork with an automatic hydraulic control system During the use of the prefabricated beam body hydraulic formwork, the hydraulic formwork needs to be measured and precisely adjusted to meet the dimensional accuracy requirements of the prefabricated beam body. At present, the hydraulic formwork with automatic hydraulic control system adopts the displacement reading of the hydraulic jack arranged at the lower part of the outer side of the formwork to indirectly measure the offset value of the formwork (usually measure the offset value of several points on the top opening of the formwork), namely relying on the displacement sensor of the hydraulic jack to indirectly measure the offset value of the hydraulic formwork, which has a large measurement error. In addition, after the prefabricated beam body hydraulic formwork is used for many times, the hydraulic formwork will be randomly deformed, resulting in a larger measurement error. The offset (deviation) value of the hydraulic formwork indirectly measured by the sensor is difficult to meet the requirements of precise adjustment of the prefabricated beam body hydraulic formwork due to the large error.
