Abstract

The invention belongs to the experiment equipment for the experiments of water conservancy and electric power building engineering casting asphalt concrete in laboratories, and especially relates to a casting asphalt concrete multi-function test and formation apparatus. Columns are fixedly connected with a pedestal, the upper ends of the columns are fixedly connected with a support plate, a screw hole arranged on the upper support plate is provided with a screw having an upper portion provided with a rotary handle in a fit manner, the end portion of the screw positioned below the upper support plate is provided with a pressure sensor, and the lower portion of the pressure sensor is fixedly connected with a steel press plate; and one of the columns is provided with a position-adjustable fixed support, the contact of a deformation sensor fixedly arranged on the fixed support cooperates with the top surface of the steel press plate, the pedestal is fixedly connected with a test die cooperating with the bottom surface of the steel press plate, and the other one of the columns is provided with a pressure and deformation display box. The apparatus has the advantages of reasonable structure, simple operation, and convenient indication, can improve the accuracies of the test indexes of the casting asphalt concrete in the laboratories, and provides scientific and accurate bases for the construction.

Description

technical field [0001] The invention belongs to experimental equipment for pouring asphalt concrete in a water conservancy and hydropower construction project in a laboratory, in particular to a multifunctional test and forming device for pouring asphalt concrete. Background technique [0002] In the current hydraulic asphalt concrete test regulations, there is only the forming method of roller compacted asphalt concrete, and there is no related specific device for the forming of cast asphalt concrete. However, most of the water conservancy and hydropower projects currently under construction use poured asphalt concrete as the anti-seepage body. The porosity of the same batch of hydraulic asphalt concrete specimens in the laboratory cannot be guaranteed to be consistent, and the test data of the indoor pouring asphalt concrete tested is not accurate enough, which affects the construction quality. Contents of the invention [0003] The purpose of the present invention is t...
