A kind of method tested using above-mentioned safety standard penetration test device that the present invention is provided, its feature is existed
In comprising the following steps that：
(1) each component of device is assembled by drawing, load operating debugging is carried out indoors, it is ensured that each part operation
Normally, the relative position of adjustment punching hammer limiting plate and telescopic tongue push button repeatedly, it is ensured that punching hammer fall away from for 760 ±
20mm；
(2) two parallel frame translation tracks are installed on rig door frame, frame is consolidated by chute with telescopic oil cylinder
Dingan County is on rig door frame, and energy left and right is being slided, and telescopic oil cylinder is fixed on to the wherein side of door frame, and ensure to stretch
When oil cylinder reaches range 95%, guide rod and rig kelly are concentric, and it is same in frame to be moved to rig kelly
Opposite side during heart position is provided with postive stop baffle, keeps frame to be in plumbness, with high-pressure oil pipe is by hydraulic motor and stretches
Contracting oil cylinder is connected by valve with rig hydraulic power source；
(3) when rig drilling arrives a certain preassigned penetration test depth, drilling is stopped, by the drilling rod and brill of rig
Head proposes drilling, and mark penetrator is connected on drilling rod, is hung in rig elevator in drilling, the stacks when putting,
When to preassigned penetration test depth, drilling rod is higher by aperture ground 0.5-1m；
(4) telescopic oil cylinder voltage supply is given, promotes frame to move to postive stop baffle along frame translation track by telescopic oil cylinder
Position, close oil path in oil cylinder when causing guide rod and concentric rig kelly, start hydraulic motor, make punching hammer rising
Certain height, and pad and the drilling rod on standard penetration device are played with the drilling rod connection of appropriate length, keep the height beaten between pad and supporting plate
0.55-1.2m is spent, weak soil takes large values, and punching hammer can be moved down when being connected with drilling rod；
(5) after the power supply of open detection display control case, pressing, which once resets, is good for, and starts hydraulic motor and simultaneously adjusts oil pressure,
Hydraulic motor drives chain drive by upper and lower gear, and the telescopic tongue push pedal being distributed on chain pushes up telescopic tongue, drives
Punching hammer is moved up, and when mobile height reaches 760mm, touch-control button makes telescopic tongue bounce back, and punching is hammered into shape along under guide rod freedom
Fall and play pad, and penetrating power is applied to penetrator by making pad and drilling rod, complete the work that punching hammers pummel penetrator into shape
Make；
(6) in shots, by detecting that the single board computer detected in display control case in storage circuit sets program control
System and record, often close proximity to blow counts N of sensor for countering, increase once, reference is used as using blow counts N to punching hammer automatically
The injection value that variable record stay wire displacement sensor is measured, by the liquid crystal window being arranged on detection display control case,
Automatically real-time blow counts N and injection amount H (cm) are shown in real time, when depth of penetration H meets or exceeds 15cm first, detection is aobvious
Show that control cabinet boombox sends voice message " play completion in advance ", show while display window N, H value zero restarts numeration
Show, when the H values recorded again meet or exceed 30cm, terminate experiment, data are stored automatically, while this examination of voice message
Test end；
(7) after off-test, hydraulic motor is closed, lays down after jointed rod, hydraulic motor is inverted at a slow speed, punching is allowed
Fallen under hammer on supporting plate, start telescopic oil cylinder, allow frame to return to left side standby position, the interior drilling rod that will be drilled with rig elevator is hung
Go out, unload standard penetration device and clean standby, and stay with polybag disturbance sample.
The present invention preferably technical scheme：The detection display control case can set the conventional form of display by button.
Such as:The pre- number that hits for beating 0-15cm, 0-10cm, which hits number, 10-20cm and hits number, 20-30cm and hit, to be counted etc..
The present invention preferably technical scheme：Also need to adjust the position of sensor for countering repeatedly in step (1), it is ensured that
It can normally count and have safety clearance；And measure conventional method is beating the energy on pad with this method respectively, it is ensured that the device
Middle punching hammer falls into play punching hammer in the energy on pad and conventional method and fall into and beats the upper energy difference of pad and be not more than 1%.
The operation principle of the present invention:The hammering device of the present invention need to be supported the use with rig, may be mounted at rig door frame
On, and can horizontally slip, machine frame movement to guide rod with rig kelly on the same line when, start hydraulic motor and lead to
Cross gear drives chain to rotate forward with lower gear, and the hook being distributed on chain drives punching hammer to move up by telescopic tongue,
When mobile height reaches 760mm, touch-control button makes telescopic tongue bounce back, and punching hammer plays pad along slide rail free-falling, by beating
Pad, drilling rod apply penetrating power to penetrator.When punching hammer is moved up, arrived when sensor for countering detects punching hammer for the first time
Reset up to system during peak, reference variable record injection amount is made with counting channel, display screen is shown in real time by programming and passes through
Enter 0-150,150-250,250-350,350-450mm pattern for hitting number or other needs, when the injection total amount that recorded
>=450mm terminates experiment.
The present invention can be supported the use with the serial rigs of existing xy or all-hydraulic drill, simple in construction, easy to use,
Automatic injection, automatic record, display, practical in real time, realizes rapid, the automation of test, substantially reduces safety wind
Danger, improves the reliability of test.
