Description

Technical Field

[0001] The invention relates to the technical field of concrete curing, in particular to a concrete curing device and method. Background Art

[0002] After concrete is poured, if it is not cured in time, the water in the concrete will evaporate too quickly, resulting in dehydration. The cement particles that have formed a gel cannot be fully hydrated and cannot be converted into stable crystals. The lack of sufficient bonding strength will cause flaking or powdery shedding on the concrete surface. Concrete curing is to artificially create certain humidity and temperature conditions so that the newly poured concrete can harden and increase its strength normally or accelerate its hardening and strength.

[0003] In engineering tunnel construction, the tunnel secondary lining concrete must not only meet the requirements of settlement deformation, but also withstand the wind pressure generated during vehicle driving to ensure that the secondary lining surface does not fall off. After the tunnel secondary lining concrete is poured, it needs to be maintained in time. The existing maintenance equipment is usually simple water spraying maintenance, which cannot cover and support the concrete. The equipment is inconvenient to adjust and cannot be applied to tunnel inner walls of different specifications, making it inconvenient to use. Summary of the invention

[0010] In an optional solution: a spring is sleeved on the outside of the connecting rod, a power piece is provided on the fixed block, and a rotating end of the power piece is connected to the driving rod.

[0011] A concrete curing method comprises the following steps: 1) Move the maintenance equipment to the working area inside the tunnel so that the top plate is located below the poured concrete layer, and use a water pump and a nozzle to spray water on the concrete layer for maintenance; 2) Pull out the film wound on the winding roller and pass it along the top of the top plate, pass the pressure rod through the two round tubes, press the pressure rod up and down, the round tube drives the sliding plate to move up and down through the cooperation with the pressure plate, the sliding plate drives the two support columns to approach each other through the cooperation of the push rod and the card slot, the support column pushes the protective plate and the top plate upward, and when the top plate at the center position contacts the concrete layer, the rise of the top plate stops; 3) Open the power parts outside the fixed block, the power parts drive the driving rod and the turntable to rotate, the turntable drives multiple telescopic rods to slide through the cooperation with the transmission rod, the telescopic rods drive the top plate to approach the concrete layer, and the movable ring descends along the through groove. When multiple top plates are in contact with the concrete layer, the support and maintenance of the tunnel concrete layer is completed.

[0012] Compared with the prior art, the present invention has the following beneficial effects: The concrete curing equipment can support and cover the concrete poured inside the tunnel to reduce the loss of water in the concrete. By pressing the pressure rod up and down, the round tube drives the sliding plate to move up and down through the cooperation with the pressure plate. The sliding plate drives the two support columns to move closer to each other through the cooperation of the top rod and the slot. The support column lifts the protective plate and the top plate upward, and the power part drives the turntable to rotate. The turntable drives multiple top plates to move upward through the cooperation with the transmission rod, thereby supporting and curing the concrete layer at the bottom of the tunnel. It can support different types of tunnel inner walls and is more convenient to use and adjust. BRIEF DESCRIPTION OF THE DRAWINGS

A through groove 302 is opened at the center of the protective plate 3, and a movable ring 15 is slidably arranged inside the through groove 302. The movable ring 15 is provided with a mounting groove 151, and a plurality of sleeves 18 are arranged inside the mounting groove 151. The sleeves 18 are fixed by bolts, and a telescopic rod 17 is slidably arranged inside the sleeve 18, and a top plate 6 is arranged at one end of the telescopic rod 17; The rotating disk 16, the movable ring 15 is fixedly provided with a fixing frame 29 on the outside, and a connecting rod 191 is slidably provided on the fixing frame 29, the top of the connecting rod 191 is fixedly connected to the support plate 8, and the bottom of the connecting rod 191 is fixedly provided with a fixing block 19, and a driving rod 28 is rotatably provided between the two fixing blocks 19, and a rotating disk 16 is provided on the outside of the driving rod 28, and support blocks 27 are provided on both sides of the outside of the movable ring 15, and a sleeve 26 is slidably provided inside the support block 27, and a movable rod 261 is slidably provided at one end of the sleeve 26, and a spring is provided inside the sleeve 26, and one end of the spring is connected to the movable rod 261, so that the elastic installation of the movable rod 261 is realized. A limit plate 14 is provided at the other end of the movable rod 261, and a transmission rod 21 is rotatably provided between the turntable 16 and the telescopic rod 17, and between the turntable 16 and the sleeve 26. A square groove 201 is provided on the outside of the support column 2, and a slider 22 is slidably provided inside the square groove 201. A support sleeve 23 is provided on the outside of the slider 22, and a limit rod 24 is slidably provided between the two support sleeves 23. A plurality of fixed teeth 25 cooperating with the limit rod 24 are provided on the outside of the sleeve 26. The top plate 6 includes a top plate A located in a vertical position and top plates B on both sides. The top plate A is connected to the telescopic rod C below. The transmission rod 21 on the telescopic rod C is located on the front of the turntable 16. The installation structure is as shown in FIG. Figure 6 As shown, the top plate B is connected to the telescopic rod D below, and the transmission rod 21 on the telescopic rod D is located on the back of the turntable 16. The installation structure is as shown in FIG. Figure 7 As shown; The lifting mechanism is arranged between the two support columns 2. The two support columns 2 are close to each other and drive the protective plate 3 and the support plate 8 to rise.
