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 arranged on the base 1, a guide column 3, a hydraulic cylinder I4, and a control system. The drive mechanism that is arranged inside the base 1 and can drive it to perform intermittent rotational movement in the horizontal plane is connected. The guide post 3 is vertically arranged on one side of the turntable 2, and a slide block 6 is slid on the guide post 3. A positioning block 7 fixed on the guide column 3 is arranged above the slider 6, and a pressure sensor is provided at the bottom of the positioning block 7, and one side of the slider 6 is connected with a pin and a hydraulic cylinder I4 for driving it to move up and down. The lifting end is connected, and the other side of the slider 6 is provided with a cantilever 8, and the cantilever 8 is composed of a fixed arm 12 and a sliding arm 13 that are slidingly fitted, and one end of the fixed arm 12 is...

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 soil engineering test instrument, in particular to a heavy-duty compaction instrument. Background technique [0002] The compaction instrument is a special instrument used for foundation filling projects such as hydraulic engineering dams, highways, railways, civil aviation airports, municipal engineering, and civil buildings. Under the action of standard compaction work, the relationship between soil moisture content and dry density is measured, so as to determine the optimal moisture content and corresponding maximum dry density of the soil sample. [0003] The indoor compaction test process is: put a sample with a certain water content into the compaction test mold in three or two layers, and hit each layer with a compaction hammer to achieve a certain number of hits. The compaction work is the product of the weight of the hammer body, the drop distance of the hammer body and the number of blows. After the soil layer is c...
