A kind of ultrafine cement filter pump and test method thereof

Abstract

The invention discloses an ultrafine cement filter pump, which comprises a pump body and a transmission control system; five nozzles are arranged outside the pump body, respectively connected with a slurry outlet pipe, a slurry inlet pipe, a drain pipe and two water inlet pipes; There is a steel cylinder inside the pump body, and a metal turntable is installed at the bottom of the steel cylinder. There are four through holes in the steel cylinder for installing the filter device, and four drainage holes and grooves in different positions are set on the outer circumference of the steel cylinder. , the groove matches the metal rod on the outside of the steel cylinder, and the metal rod controls the action through the transmission control system; the transmission belt in the transmission control system is connected with the metal turntable. The beneficial effect of the present invention is that it has the advantages of simple structure, simple operation, convenient use, easy maintenance, convenient debugging, etc., and is well sealed and durable, and can also replace different sizes of filter screens according to different grouting requirements, and is suitable for engineering sites Partial grouting micropore water plugging and micropore grouting in the laboratory.

Description

technical field [0001] The invention relates to the technical field of rock grouting, in particular to an ultrafine cement filter pump and a test method thereof. Background technique [0002] With the increase of the depth of underground engineering construction, the deep complex geological environment such as the increase of ground stress and the increase of water inflow becomes more and more obvious. Engineering practice shows that water seepage may still occur in the deep part of the 1,000-meter-deep shaft of the coal mine after grouting, and the seepage mainly comes from the surface seepage of micro-cracks in the deep sedimentary sandstone. [0003] Ordinary cement grout is difficult to grout to block water seepage on the surface, and ultra-fine cement grout is the main grouting material for micro-crack water plugging because of its greenness, low cost, and small particle size. Agglomeration inevitably occurs during the grout configuration process, resulting in too larg...
