Embodiment Construction

[0023] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0024] see Figure 1 to Figure 5 , a kind of subgrade compactness test detection equipment provided by the present embodiment comprises a weighing device, a water immersion tank 8 and a baking oven 2, the weighing device is provided with a support frame, and the support frame is provided with a water immersion tank and a baking oven, There is a clamp in the oven, which clamps and fixes the roadbed sample to be tested. There is a heater in the oven. The heater provides the drying heat of the oven to dry the surface of the clamp. The subgrade samples to be tested; the immersion tank is used for water immersion of the subgrade samples to be tested; the weighing device is used to weigh the subgrade samples to be tested, including the subgrade samples to be tested that are basically weighed and dried Weigh and weigh the subgrade samples to be tested after ...

Abstract

The invention discloses roadbed compactness test detection equipment. The equipment comprises a weighing device, a soaking box and a baking box, wherein the soaking box and the baking box are arranged on the weighing device, a rotatable clamping piece is arranged in the baking box, and the clamping piece clamps a roadbed sample to be detected. The clamping piece is driven by a first driving device to drive the to-be-detected roadbed test to be circularly rolled and dried in the baking box, the drying speed is high, moisture of a test sample is effectively discharged, dryness of the test sample is guaranteed, and detection accuracy is improved; besides, the to-be-detected roadbed sample is subjected to oscillation water immersion in the water immersion box, thorough water immersion of the sample is guaranteed, detection accuracy is improved, meanwhile, the arranged weighing device can detect the weight change of the sample in real time, and the initial weight of the to-be-detected roadbed test, the dried to-be-detected roadbed sample and the weight of the water-immersed to-be-detected roadbed sample are obtained; and compactness of the roadbed can be conveniently calculated.

Description

technical field [0001] The invention relates to the technical field of roadbed testing equipment, in particular to a roadbed compactness test and detection equipment. Background technique [0002] Compactness refers to the ratio of the volume of the solid material part of the material to the total volume, and refers to the ratio of the dry density of soil or other road construction materials after compaction to the standard maximum dry density, expressed as a percentage. Degree) is one of the key indicators for the quality inspection of subgrade and pavement construction, which represents the density status after on-site compaction. The higher the degree of compaction, the greater the density, and the better the overall performance of the material. When the existing subgrade density is tested, the subgrade test contains moisture inside and cannot be completely dried, and when the water irrigation method is used for testing, the water immersion is not thorough, resulting in i...
