Abstract
The utility model discloses a novel static sounding feeler lever which comprises a feeler lever main body. The feeler lever main body comprises a conical cusp, a sleeve is arranged at the rear portion of the conical cusp, a lengthened connector is arranged at the rear portion of the sleeve, a lengthened rod is arranged at the rear portion of the lengthened connector, and static sounding equipment is positioned in the feeler lever main body. The novel static sounding feeler lever can be in friction with a hole wall in a low probing process to move up through a hole type pressure sensor and a lateral wall type pressure sensor, a chambering plug is arranged on the sleeve to guarantee lubrication effects of slurry or water on the hole wall, and the novel static sound feeler lever can continuously, quickly and accurately test soil specific penetration resistance in a soil engineering model tests. The diameter of the feeler lever is reduced so as to reduce soil squeezing effect on model test soil in a penetration process and improve test accuracy of limited soil layers. The novel static sounding feeler lever is simple in structure, convenient to manufacture and maintain and favorable for improving penetration depth.
Description
Technical field
The utility model relates to a kind of feeler inspection feeler lever, is specially a kind of novel static sounding feeler lever, belongs to the highway construction apparatus field.
Background technology
Static sounding is to adopt the injection pressure of power source that the feeler inspection probe is pressed into a kind of engineer geological prospecting method that soil layer is implemented in-situ test.In the prior art, normally connected and composed successively by feeler lever, water out adapter, storage-pole and probe body without the static sounding feeler lever of cable, water out adapter arranges one or two radially weep hole.The mud that injects from feeler lever or water flow out from the weep hole of storage-pole top water out adapter, when being conducive to improve the static sounding degree of depth, also can avoid current that the soil layer that the probe body touches is produced disturbance alleviating the feeler lever penetration resistance.Yet the weep hole of in feeler inspection practice, finding existing static sounding feeler lever water out adapter without cable in repeatedly test, carry and occur to block in the process of feeler lever and affect lubricant effect.
