Embodiment 1

[0019] Embodiment 1: Stainless steel is used to make the ring 2. The diameter of the ring 2 can be determined according to the amount of samples to be tested each time. Generally, a ring 2 with a diameter of 1 meter can be placed at most 60 pieces of 4×4×16cm at a time. Rectangular sample 11. According to the number of test samples 11 that can be placed, use an equal number of stainless steel angle steel or stainless steel flat steel as the sample holder 9, one end of which is welded on the outer ring of the circle perpendicular to the circular surface, and the other end is suspended and fixed on the outer side of the circle of the ring 2. Rubber gear teeth; make the ring support 7, and the ring 2 is installed on the ring support 7 through the shaft, so that the ring 2 can freely rotate on the ring support 7, thereby forming a rotating frame.

[0020] Select the motor 6, which is generally two motors, and its power is determined according to the weight of the ring 2 and the sa...

Abstract

This invention relates to one dry and wet and fresh water and sea water recycle analogue device , which comprises shower spray head, water tank, tank rack, drive system, rotation rack and erosion liquid tank, wherein, the drive system gear is fixed onto motor axis connected to controller; the rotation rack is composed of round ring, round rack and specimen rack and the round ring is fixed on other side of round rack to make it vertical to earth level; the drive gear shape and round ring shape are meshed with one side set with erosion liquid tank and down part in the tank; specimen rack end is vertical to round ring outer one; the spray head is one round ring fixed down spray water tank rack.

Description

technical field [0001] The invention relates to a dry-wet cycle and fresh water-sea water cycle simulation device. Background technique [0002] At the estuaries of rivers and rivers in our country, many cross-river and sea-crossing projects are planned. Due to the effect of tides, seawater pours into rivers and rivers at high tide, submerging concrete structures below the tidal range, and making concrete withstand chloride salts and various sulfuric acids. Salt erosion; when the tide ebbs, the river and river water begin to erode the concrete, making it subject to fresh water erosion, while the concrete in the tidal range area is exposed to the air. Therefore, the concrete structures of these projects are in the corrosive environment of dry-wet cycle and fresh water-sea water cycle. [0003] Concrete in the marine environment is called marine concrete or marine concrete. Its main damage form is that Cl ions in the sea invade the concrete protective layer and cause corrosio...
