Anti-crack tunnel concrete detection containing comparison device

Abstract

The invention discloses an anti-crack tunnel concrete detection containing comparison device in the technical field of concrete.The anti-crack tunnel concrete detection containing comparison device comprises a base, two comparison boxes are fixedly connected to the top of the base, thermometers are installed on the upper portions of the two comparison boxes, and electric push rods are vertically installed in the centers of the tops of the two comparison boxes; and a pressing plate is fixedly connected to the telescopic end of the bottom of each electric push rod, concrete block fixing assemblies are installed at the bottoms of inner cavities of the two comparison boxes, a three-way pipe is fixedly connected and communicated between the two comparison boxes, and warm air blowers are arranged above the two comparison boxes. The device is suitable for the comparison test of the anti-crack concrete block. Through the air cooler and the warm air blowers, wide-range temperature testing can be carried out on the concrete block, and therefore the anti-freezing and heating conditions of the concrete block are determined; the compressive strength of the concrete block can be tested through each electric push rod, and the compressive strength of two groups of concrete is compared.

Description

technical field [0001] The invention relates to the technical field of concrete, in particular to a holding contrast device for detecting crack-resistant tunnel concrete. Background technique [0002] Concrete, referred to as "concrete" for short: refers to the collective name of engineering composite materials in which aggregates are cemented into a whole by cementitious materials. Generally speaking, the term concrete refers to the cement concrete obtained by using cement as the cementitious material, sand and stone as the aggregate; mixed with water (may contain admixtures and admixtures) in a certain proportion, and stirred. Concrete, which is widely used in civil engineering. [0003] Concrete is one of the most important civil engineering materials today. It is composed of cementitious materials, granular aggregates (also known as aggregates), water, and if necessary, admixtures and admixtures prepared in a certain proportion, uniformly stirred, densely formed, cured...
