Embodiment Construction

[0011] Such as figure 1 with figure 2 As shown, a heavy-duty compaction instrument includes a base 1, a rotary table 2, a guide column 3, a hydraulic cylinder I4, and a control system provided on the base 1. The rotary table 2 is provided with a test mold barrel 5, the rotary table 2 and A drive mechanism that is arranged inside the base 1 and can drive it to perform intermittent rotation in a horizontal plane is connected. The guide post 3 is vertically arranged on one side of the rotating table 2, and a slider 6 is slidably provided on the guide post 3. Above the slider 6 is provided a positioning block 7 fixed on the guide post 3, the bottom of the positioning block 7 is provided with a pressure sensor, one side of the slider 6 is connected to a hydraulic cylinder I4 for driving it up and down through a pin. The lifting end of the sliding block 6 is connected with a cantilever 8 on the other side of the sliding block 6. The cantilever 8 is composed of a slidingly fitted fix...

Abstract

A heavy-duty compaction device relates to a soil engineering tester, which comprises a base, a rotary platform arranged on the base, a guide column, a hydraulic cylinder I and a control system, wherein a mold testing barrel is arranged on the rotary platform; the guide column is vertically arranged on one side of the rotary platform; a sliding block is arranged on the guide column in a sliding manner; a positioning block fixed on the guide column is arranged above the sliding block; a pressure sensor is arranged at the bottom of the positioning block; one side of the sliding block is connected with the lifting end of the hydraulic cylinder I used for driving the sliding block to move up and down via a pin, a cantilever for clamping and releasing a compaction hammer is arranged on the other side of the sliding block; a signal detection device and a signal detection area are respectively arranged on a clamping device of the cantilever arm and the corresponding part of the compaction hammer; the pressure sensor and the signal detection device are connected with the control system; the control system controls a hydraulic cylinder II and the hydraulic cylinder I to stretch out and draw back. The heavy-duty compaction device enables the falling distances of the compaction hammer to be the same, is uniform in force for hammering samples, and improves test accuracy.

Description

Technical field [0001] The invention relates to a geotechnical test instrument, in particular to a heavy-duty compaction instrument. Background technique [0002] The compactor is a special instrument used for foundation filling projects of hydraulic engineering dams, highways, railways, civil aviation airports, municipal engineering, and civil buildings. The relationship between soil moisture content and dry density is measured under the action of standard compaction work, so as to determine the optimal moisture content of the soil sample and the corresponding maximum dry density. [0003] The indoor compaction test process is: put a sample with a certain moisture content in three or two layers into the compaction test mold cylinder, and hit a certain number of blows with a compaction hammer for each layer. The compaction work is the product of the weight of the hammer, the falling distance of the hammer and the number of strikes. After the soil layer is compacted to a full cylin...
