Feeler lever nipple separate and connect adapter coupling, adjustment rotation touch investigating lathe main shaft highly adapter coupling is connected with casing,
Release casing spider to grip casing, risen by the main shaft of rotation touch investigating car hydraulic device and pull out casing, hollow transmission rod
Rise and pull out at the same time therewith with detector assembly, screw pressure-bearing plate is abandoned in test hole.
5. the application method of spiral plate Deep Plate Load Test system according to claim 4, it is characterised in that further include with
Lower step：If carrying out next depth experiment in same test hole, first resultant signal cable is separated with measurement data record instrument, will
Hollow transmission rod upper end separates with the feeler lever nipple of rotation touch investigating car hydraulic device main shaft and connects adapter coupling, adjustment rotation
Turning feeler inspection lathe main shaft highly makes adapter coupling be connected with casing, starts rotation touch investigating car hydraulic device and passes through casing, detector
Assembly makes screw pressure-bearing plate rotate injection in test hole position, increases casing and hollow transmission rod section by section and at the same time by resultant signal cable
Drawn from increased hollow transmission rod, after screw pressure-bearing plate reaches next default subterranean depth, stop sleeve rotating injection, will
Resultant signal cable repeats abovementioned steps (5) after being connected to measurement data record instrument, (6) are tested.
