Abstract
The invention discloses a horizontal coil system and method for monitoring high-layer pumping pressure of large flowing concrete. The system comprises a concrete conveying pipe with one end connected to the pump truck and a pressure sensor. The concrete conveying pipe is arranged in fold line type horizontally, comprising a straight pipe and an elbow. Monitoring points on the concrete conveying pipe include the end monitoring points at the liquid inlet and liquid outlet as well as a series of intermediate monitoring points arranged on the straight pipe; the pressure sensor is provided at the intermediate monitoring points and has a insertion depth of 1-4mm; an height-adjustable tubular support is provided at the bottom of the straight pipe; and all pressure sensors are connected to the data processing terminal. The invention can not only calculate the pressure drop of the elbow or the straight pipe and the whole-course pressure drop, and then calculate the pressure drop of the super high-rise pumping, but also effectively achieve whole course monitoring for the pipeline, which conforms to the monitoring specification and provides guidance for formula fitting between the actual pressure drop and the concrete viscosity.
Description
technical field [0001] The invention relates to the technical field of super-high-rise pumping concrete, in particular to a horizontal coil system and a method for monitoring the pumping pressure of super-high-rise concrete in a large fluid state. Background technique [0002] At present, modern super high-rise buildings have become one of the important symbols of the economic and social development and urbanization process in mainland China, and have also become one of the major issues in the development of China's construction industry. In super high-rise concrete pumping construction, with the increase of pumping height, the delivery pressure of concrete is also increasing. For super high-rise buildings with a verticality greater than 400M, high-strength concrete is generally used with high viscosity. The pressure of the pump needs to be above 20Mpa, the higher the pumping distance, the greater the pumping pressure, the higher the requirements for the pump, and the more d...
