Dual-mode glue extruding type dynamic pressure testing strainmeter

The invention relates to the technical field of dynamic pressure testing devices, in particular to a dual-mode glue extruding type dynamic pressure testing strainmeter which is applicable to dynamic pressure testing of rock soil and mines based on strain calculation. A body comprises a measuring line, an orifice end cover, an inclusion base tube, a hole bottom end cover and a glue containing tube, wherein the orifice end cover, the inclusion base tube, the hole bottom end cover and the glue containing tube are connected in sequence. The orifice end cover and the hole bottom end cover are each provided with a liquid inlet hole, a liquid guide hole and an annular liquid guide groove which are communicated in sequence, and the annular liquid guide grove is formed in the outer surface. Each liquid guide groove is covered with a liquid expansion bag in a surrounded mode. The outer surface of the orifice end cover is provided with a blocking ring. The liquid inlet hole of the orifice end cover and the liquid inlet hole of the hole bottom end cover are communicated through a liquid tube penetrating through the inclusion base tube. The liquid tube is sleeved with an expandable sleeve. The inclusion base tube is provided with a glue outlet hole communicated with a glue containing cavity. The right end of a glue containing tube is connected with a piston tube in a sliding and sleeving mode. The dual-mode glue extruding type dynamic pressure testing strainmeter is good in sealing effect; the strainmeter and a measured drill hole can be coaxial easily, so the reliability and effectiveness of strain measurement data are improved, and the installation success rate is increased.
