Description

Technical Field

[0001] The utility model relates to the field of material maintenance, in particular to an indoor maintenance device for tunnel slag machine-made sand concrete. Background Art

[0002] Concrete is one of the most important engineering materials in the contemporary world. With the development of the industry over the years, the research on concrete has become more in-depth, and there are more designs and requirements for the curing of concrete materials. Among them, tunnel slag machine-made sand concrete is designed to reasonably dispose of the slag generated during excavation. The machine-made sand is prepared with the slag generated during tunnel excavation as raw material, so that the machine-made sand can be involved in the subsequent construction of concrete.

[0003] The full curing of tunnel slag machine-made sand concrete specimens will have a positive impact on chemical erosion experiments, freeze-thaw experiments, and harmful ion penetration experiments, especially for cement concrete specimens with a large amount of water reducers. Studies have shown that the shrinkage of such concrete increases sharply after initial and final setting. The full hydration of concrete during the curing process can reduce its shrinkage damage and prevent the appearance of early plastic shrinkage cracks and long-term shrinkage cracks. In addition, it can also improve the density of concrete, effectively prevent the erosion of concrete by chemical substances, and prevent chemical reaction cracks in concrete caused by harmful chemicals.

[0004] Curing operations are usually carried out in a curing room. Generally, a curing rack is set up in the curing room to cure the concrete specimens, and a spray system installed on the top of the curing room is used to spray the curing room. The curing racks in existing concrete curing rooms are generally steel or aluminum alloy shelves with hollow bottoms. During curing, the concrete specimens are placed on the curing racks, and the spray system installed in the curing room is started at a fixed time to spray the atomized gas on the specimens to be cured.

[0005] However, this type of spraying has certain drawbacks. On the one hand, the existing spraying system is set at the top of the curing room, which makes it impossible to spray liquid or steam evenly on all specimens, seriously affecting the curing effect. On the other hand, the shelves of the curing rack are usually set horizontally. This design of shelves has the risk of water accumulation, and there is also a risk of affecting the treatment effect with the contact surface of the shelves. When placing the specimens, it is also necessary to avoid the position of the specimens on the upper shelves to avoid affecting the treatment efficiency due to being blocked. Therefore, a curing device that can achieve a uniform treatment effect is urgently needed to be developed. Summary of the invention

[0006] The object of the present invention is to provide a tunnel slag machine-made sand concrete indoor curing device, which can evenly cure concrete specimens in a smaller space and avoid unreliable results caused by long-term contact with moisture or excessive drying.

[0007] To achieve the above-mentioned purpose, the utility model discloses an indoor curing device for tunnel slag machine-made sand concrete, which is composed of two curing frames and a partition frame arranged between the curing frames, wherein the partition frame includes a pipe frame, a water supply pipe, and an atomizer, wherein the pipe frame is arranged vertically to the ground, one end of the water supply pipe is connected to the pipe frame and extends into the pipe frame, and an atomizer for discharging water is arranged on the water supply pipe;

[0008] The maintenance rack is composed of a frame, a drawer rack, a water storage tank, a temperature sensor, and a humidity sensor. The drawer rack is provided with a plurality of placement holes, which are obliquely arranged on the frame. Two opposite edges of the drawer rack are provided with hooks connected to the frame. The temperature sensor and the humidity sensor are arranged on the frame. The water storage tank is connected to the part of the water supply pipe extending into the pipe rack through a pipe.

[0009] Preferably, the drawer frame has an inclination angle of no more than 30° to prevent the specimen from shaking due to an excessively large angle.

[0010] Furthermore, the partition frame also includes an atomizer valve, which is arranged at the connection between the atomizer and the water supply pipe and is used to control the opening and closing of the atomizer. The atomizer valve can be an automatic control valve. After connecting to the control device, the opening and closing of the valve can be remotely controlled, which saves time for manual adjustment and can also prevent safety problems caused by volatilization of reagents on the surface of the specimen and close operation of operators under special circumstances.

[0011] The partition frame also includes a water supply pipeline valve, which is arranged at the interface between the water supply pipeline and the pipeline frame, and can control whether water flows in the water supply pipeline, thereby adjusting the treatment of the test pieces on the same layer.

[0012] The partition frame also includes a water temperature display, which is arranged on the pipe frame of the partition frame, extends into the pipe frame and is connected to the water supply pipe, and is used to observe the water temperature for health care in real time and record the treatment conditions in time.

[0013] In order to achieve a consistent spraying effect, the inclination angles of the drawer racks on the two curing racks are complementary to each other, that is, they are in a mirror-symmetrical state with respect to the partition racks.

[0014] A pair of opposite sides in the placement hole of the drawer rack are not sealed, and a guide groove is arranged on the bottom surface of the placement hole so that water can flow out and does not accumulate in the placement hole, thereby reducing the impact on the test piece.

[0015] Preferably, the temperature sensor is arranged at the center of the entire skeleton, and there are no less than two humidity sensors, which are on the same horizontal line as the temperature sensor and are arranged on both sides of the temperature sensor.

[0016] Preferably, the atomizers correspond to drawer racks, and each drawer rack corresponds to two atomizers.

[0017] In order to make the spraying range more controllable and concentrated, the water supply pipe is parallel to the ground and arranged along the arrangement direction of the drawer rack, and the height of the water supply pipe is at the center line height of the drawer rack.

[0018] A pulley may also be provided on the side of the partition frame in contact with the ground, so as to facilitate adjustment of the position of the partition frame and maintenance of the water supply pipeline and the atomizer.

[0019] The utility model has a reasonable structure. The drawer frame is arranged obliquely, which can make the health-preserving water in the atomizer be evenly sprayed on the test piece. The two sides of the placement hole of the drawer frame are not sealed, and the bottom surface is also provided with a guide groove, which can lead out the water entering the placement hole in real time, so that there is no water accumulation at the bottom of the test piece. At the same time, the side and bottom surfaces of the test piece can be stably exposed to the humid environment, so as to achieve the effect of uniform maintenance.

[0020] The use of drawer racks is also conducive to grouping, marking and observing the specimens according to other experimental conditions. In actual operation, drawer racks with placement holes of different sizes are designed according to the different sizes of specimens.

[0021] In the health-care device, the inclined drawer rack design also saves space in the health-care room. More health-care devices can be installed in the health-care room of limited area. When using the health-care device, the spraying equipment on the top of the health-care room can be used for treatment, and the overall range of condition selection is wider.

[0022] The device as a whole can use manually adjusted valves to control whether water is flowing out of each layer and the amount of water flowing out. When the valve or atomizer valve on the water supply pipe is connected to the automatic control system, the health environment created by the health device can reach a more controllable and adjustable level.

[0031] like Figure 1 The tunnel slag machine-made sand concrete indoor curing device shown is composed of two curing frames and a partition frame installed between the curing frames. The partition frame includes a pipe frame 9, a water supply pipe 10, an atomizer 11, and a water temperature display 12. The curing frame is composed of a frame 1, a drawer frame 2, a water storage tank 3, a temperature sensor 4, and a humidity sensor 5.

[0032] like Figure 4 As shown, the pipe rack 9 is perpendicular to the ground, one end of the water supply pipe 10 is connected to the pipe rack 9 and extends into the pipe rack 9, and an atomizer 11 for water outlet is fixed on the water supply pipe 10. The atomizers 11 are symmetrically arranged on both sides of the water supply pipe 10, and their positions correspond to the drawer racks 2. Each drawer rack 2 corresponds to two atomizers 11. The water temperature display 12 is fixed on the pipe rack 9 of the partition frame, extends into the pipe rack 9 and is connected to the water supply pipe 10, and is used to observe the water temperature for health care in real time and record the treatment conditions in time. In order to make the scope of spraying treatment more controllable and centralized, the water supply pipe 10 is parallel to the ground and along the arrangement direction of the drawer rack 2, and the height of the water supply pipe 10 is at the center line height of the drawer rack 2.

[0033] like Figure 2 As shown, the drawer rack 2 is hung obliquely on the frame 1 through the hook 8, the temperature sensor 4 and the humidity sensor 5 are fixed on the frame 1, the temperature sensor 4 is fixed at the center of the frame 1, and there are no less than two humidity sensors 5, which are on the same horizontal line as the temperature sensor 4 and fixed on both sides of the temperature sensor 4. In order to achieve a consistent spraying effect, the inclination angles of the drawer racks 2 on the two curing racks are complementary angles, that is, they are in a mirror symmetric state with respect to the partition. Figure 1 The water storage tank 3 shown has a heat preservation function and is connected to the part of the water supply pipe 10 extending into the pipe rack 9 through a pipe.

[0034] like Figure 3 As shown, there is a placement hole 6 on the drawer frame 2, and the drawer frame 2 is tilted at an angle of no more than 30° to prevent the specimen from shaking due to an excessively large angle. The two sides of the placement hole 6 of the drawer frame 2 are not sealed, and there are two parallel concave guide grooves 7 on the bottom of the placement hole 6, so that water can flow out and does not accumulate in the placement hole 6, thereby reducing the impact on the specimen.
