Description
Technical field
The present invention relates to load measurement field, a kind of slope pavement load test instrument is particularly belonged to.
Background technology
Plate is the common method for detecting Subgrade Compaction Quality, mainly includes ground coefficient K30 experiment
And secondary deformation modulus Ev2 experiments.Traditional plate method be by different-diameter loading plate repeated loading or
Unloading, soil compaction quality is judged according to its load and sinking magnitude relation.Traditional detection instrument shows certain in use
Weak point, on the one hand because roadbed considers that draining needs in design, certain slope can be made from line midline to both sides
Weathering, such as 2%, 4%, the level of loading plate during for guarantee test generally digs test surfaces to level, or adopt before the test
Test surfaces are adjusted to level with sand, gypsum putty etc. is dried, test very not aspect, operation difficulty is big.
The content of the invention
It is an object of the invention to provide a kind of slope pavement load test instrument, the test for being specially adapted for slope pavement will
Ask, soil compaction quality is judged according to load and sinking magnitude relation, related data measurement is accurate, for different ramp angles road surfaces
Can freely it adjust.
Technical scheme is as follows：
A kind of slope pavement load test instrument, includes measurement plate, and measurement plate middle part is carried to be rotatablely equipped with boss, boss

Face, lower surface are respectively equipped with optoelectronic position block, pressure sensor, and the cylinder body of pneumohydraulic pressure-cylinder is provided with relative with optoelectronic position block
The photoelectric displacement sensor answered, photoelectric displacement sensor, pressure sensor are connected to controller, and controller connection statistics have shown
Device, rotating disk is provided with angle index line, and rotating disk side is provided with the pointer corresponding with angle index line, and measurement plate both sides lead to respectively
Too high support bar, low support bar are installed on slope pavement, and high support bar, low support bar are connected with measurement plate using screw thread respectively
Connect.
Fixed plate is set with outside the cylinder body of the pneumohydraulic pressure-cylinder, photoelectric displacement sensor is located at fixed plate both sides respectively.
Angle retaining mechanism is provided between described rotating disk and boss.
Described bearing plate lower surface, which is provided with standing groove, standing groove, is placed with pressure sensor, loading plate lower surface, pressure
Force snesor is pressed on slope pavement.
Rotating disk of the present invention can be with rotational angle with boss, and according to the gradient of slope pavement, pneumohydraulic pressure-cylinder can be with rotating disk
Rotate and adjustment angle, drive load plate pressure to put road surface to be detected by pneumohydraulic pressure-cylinder, and by pressure sensor, photopotential
Load pressure signal and road surface subsidence signal are transported to controller by displacement sensor, are calculated by the processing of controller, and show
Over the display, it is specially adapted for the test request of slope pavement, soil compaction quality is judged according to load and sinking magnitude relation,
Related data measurement is accurate, can freely be adjusted for different ramp angles road surfaces.
