The utility model relates to civil engineering work field tests, particularly a kind of measurement mechanism of measuring soil pressure after flexible retaining wall wall.
Background technology
Earth pressure test is an important test event of field of civil engineering, is the important content that civil engineering work detects.Pressure transducer is a kind of sensor the most conventional in industrial practice, and the soil pressure cell that is commonly used to measure soil pressure is mainly to utilize pressure transducer manufacture to form.Use soil pressure cell can measure the soil pressure after flexible retaining wall wall, after measuring barricade wall during soil pressure, soil pressure cell is vertical to be embedded in barricade to be measured, but in actual use, due to the distortion of the flexible retaining wall wall back of the body, soil pressure cell tilts to deflection, and makes the soil pressure of measurement inaccurate.
Utility model content
The technical problems to be solved in the utility model be to provide a kind of can Real-Time Monitoring because the distortion of the flexible retaining wall wall back of the body causes the deflection angle that soil pressure cell tilts, and can obtain according to the deflection angle of soil pressure cell and the soil pressure recording value the measurement mechanism of real standard direction soil pressure.
For solving the problems of the technologies described above, the utility model has adopted a kind of soil pressure measurement mechanism, and this device comprises a soil pressure cell, is installed with a dip measuring device on described soil pressure cell.
The described soil pressure cell back side is provided with a plurality of threaded holes, and on described dip measuring device, correspondence is provided with a plurality of through holes, and described dip measuring device is mounted by means of bolts on soil pressure cell, and described bolt is fixedly mounted in threaded hole through through hole.
The described soil pressure cell back side is provided with a plurality of joint pins, on described joint pin, is provided with screw thread, and on described dip measuring device, correspondence is provided with a plurality of through holes, and described joint pin is respectively through through hole, and the joint pin upper end of passing through hole is provided with nut.
Described dip measuring device is obliquity sensor.
The utility model is simple in structure, the obliquity sensor of measuring angle of inclination is fixedly mounted on the soil pressure cell of measuring soil pressure, this device can be monitored the location status of soil pressure cell in real time, record angle of inclination and the force value of soil pressure cell simultaneously, thereby according to the angle recording and force value, carry out the size of inverse horizontal earth pressure; This device has solved the problem that soil pressure is measured after flexible retaining wall wall, make flexible retaining wall wall after soil pressure force measurement more accurate.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
Embodiment mono-
As shown in Figures 1 to 3, at three threaded holes 4 of the back side of soil pressure cell 1 processing, correspondingly at three through holes 5 of obliquity sensor 2 processing, use bolt 3 through the through hole 5 on obliquity sensor 2, bolt 3 is screwed in the threaded hole 4 on soil pressure cell 1, thereby obliquity sensor 2 is fixedly mounted on soil pressure cell 1.
Embodiment bis-
As shown in Fig. 3 to 5, three joint pins 6 are set on soil pressure cell 1, on three joint pins 6, be provided with external thread, correspondingly on obliquity sensor 2, process three through holes 5, joint pin 6 is respectively through through hole 5, then at joint pin 6 upper end mounting nuts 7, fastening nut 7, can be fixedly mounted on obliquity sensor 2 on soil pressure cell 1.
While using this device, this device is imbedded in flexible retaining wall to be detected, when flexible retaining wall deforms, caused soil pressure cell 1 run-off the straight, now by the obliquity sensor 2 being fixedly connected with soil pressure cell 1, can obtain the angle that soil pressure cell 1 tilts; Record the force value of soil pressure cell 1 pressure simultaneously, according to angle of inclination and force value, just can calculate the force value of horizontal direction, be i.e. actual soil pressure after flexible retaining wall wall.
