Embodiment Construction
[0024] The present invention will be further described below in conjunction with the accompanying drawings.
[0025] Such as Figure 1 to Figure 4 As shown, a device for simulating the coupling of hydraulic concrete freeze-thaw environment and its wear performance of the present invention includes a support frame 1 anchored on the ice, and the outer frame of the support frame 1 is welded by 4 box-shaped steel pipes. A small hole is punched on the box-shaped steel pipe, and the support frame 1 can be fixed on the ice surface with a typical ice anchor 2 through the preset hole on the ice surface. The top and bottom of the long-side box-shaped steel pipes of the support frame 1 have a strip-shaped supporting piece 3 respectively. One side of the supporting piece 3 is welded and fixed with the box-shaped steel pipe, and the other side is suspended inside the supporting frame 1. Composed of the running track of the internal frame. The internal frame is welded by box-shaped steel ...

The invention discloses a device for simulating coupling of a hydraulic concrete freeze-thaw environment and wear resistance thereof, and the device comprises an external temperature regulating box, wherein the side wall of the temperature regulating box is welded with a support frame of the device through a steel pipe, a plurality of through holes are formed in the frame of the support frame, iceanchors are arranged in the through holes, and support pieces are arranged on two sides below the support frame; the support pieces on the two sides form a guide rail, and a translation frame is installed on the guide rail; a telescopic device is hinged to the translation frame, a telescopic rod of the telescopic device is hinged to a sample support, the sample support slides along the guide rail, a supporting plate is installed on the sample support, a supporting shaft and a motor are installed on the supporting plate, and the motor drives the supporting shaft to rotate; a concrete test piece is installed on the supporting shaft, and the motor drives the concrete test piece to rub with ice. According to the invention, the concrete test adopts a cylindrical shape, and the situation of intermediate stop does not occur in the test rotation process, so the concrete test and ice can be kept in a continuous wear motion state all the time.
Description
technical field [0001] The invention relates to a device and a method for simulating the coupling of the freeze-thaw environment of hydraulic concrete and its wear performance, belonging to the field of concrete. Background technique [0002] Due to its excellent mechanical properties, concrete has become the most widely used building material at present. With the continuous improvement of underwater technology, hydraulic concrete is also playing a huge role. However, in the hydraulic concrete structure in cold regions, when the temperature drops sharply, the ice cubes produced in the water tend to have a greater impact on the hydraulic concrete. While ice wear on hydraulic concrete structures is an ongoing problem, the continued wear of ice on hydraulic concrete can lead to a loss of concrete structural integrity. Therefore, testing the long-term ice abrasion performance of concrete samples is very important for the durability evaluation of hydraulic concrete structures. ...
