Soil engineering compaction test equipment

Abstract

The invention discloses soil engineering compaction test equipment which comprises a rotatable workbench, a soil engineering compaction mold is arranged on the rotatable workbench, a vibrating rod is arranged in the center of the soil engineering compaction mold, the vibrating rod penetrates through the rotatable workbench and is fixed to a base, and a compaction device is installed at the top of the vibrating rod. The compaction device comprises a fixing frame fixed to the top end of the vibrating bar, a compaction hammer and a rolling wheel, the compaction hammer and the rolling wheel are movably installed on the fixing frame through a compaction guide rod and a rolling guide rod correspondingly, the compaction guide rod and the rolling guide rod are connected with a compaction transmission device and a rolling transmission device correspondingly, and a rocker device is installed on the rolling wheel; the compaction transmission device, the rolling transmission device, the vibrating bar, the rocker device and the rotatable workbench are electrically connected with a controller, and the controller is connected with a motor. According to the test equipment, double hammers are symmetrically arranged, and vibration, striking and grinding are synchronized in the compaction process, so that a soil body is embedded and compacted to obtain the maximum compactness, and the test process is closer to an actual construction site.

Description

technical field [0001] The present invention relates to a test device, more particularly, to a geotechnical compaction test device. Background technique [0002] Soil is used as filling material, such as building roads, dams, airport runways, sports fields, building foundations and foundation backfilling, etc. The problem of filling soil compaction is often encountered in projects. After handling the uncompacted fill, the original structure has been destroyed, there are many pores and cavities, the soil quality is uneven, the compression is large, the strength is low, and the water resistance is poor. In order to improve the engineering properties of the filling, increase the strength of the soil, and reduce the compressibility and permeability of the soil, the soil must be compacted to a certain standard by using methods such as hammer compaction, mechanical rolling or vibration to meet certain standards. engineering quality standards. The compaction meter is a kind of co...

Problems solved by technology

However, in actual use, when the water content is too large or too small, the error of the test results obtained by simple compaction is too large. At the same time, there are factors such as the vibration of the road roller on the construction site that affect the construction quality. However, the existing The compaction instrument cannot take into account the influencing factors of the actual construction site
