Abstract

The invention relates to high-precision cement paste density and flow monitoring equipment, which comprises a cement mixing pile machine, a grouting pump and a mixing tank, and is characterized by further comprising a mass flow meter, a water injection pump, an anti-blocking detection mechanism and a clean water tank. According to the invention, the mass flow meter is installed on a grouting pipeaccording to the field working condition to measure cement paste density and flow data in real time, wherein due to the fact that the data can be collected for a long time, the possibility of manual construction cost participation during spot check is avoided; the mass flow meter belongs to high-precision equipment, and after the grouting of the slurry is stopped, a certain amount of slurry is stored in the mass flow meter so as to cause clogging even damage of the mass flow meter; by additionally arranging the waterway flushing mechanism, mud is cleaned, so that waste of water resources is avoided; and the anti-blocking detection mechanism is further additionally arranged to detect whether cleaning is completed, so that the problem that water resources are wasted due to insufficient flushing or excessive flushing is avoided.

Description

technical field [0001] The invention relates to a high-precision cement slurry density flow monitoring device. Background technique [0002] At present, the construction control system of cement mixing piles mostly adopts source control for the control of cement consumption, that is, the use of mixing equipment to control the amount of cement mixed. During the construction process, the well-mixed cement slurry flows out of the mixing equipment and will pass through an open mixing tank and then pumped into the grouting pipe for grouting construction. The daily supervision work controls the density of the cement slurry in the mixing tank through a certain frequency of random sampling inspection, which increases the influence of human factors, and the density of the cement slurry used for pouring cannot be fully guaranteed in the construction process control. Contents of the invention [0003] The technical problem to be solved by the invention is to provide a high-precision...
