Description

Technical Field

[0001] The invention relates to the technical field of self-healing concrete protection, and in particular to a waterproof device for a self-healing concrete structure. Background Art

[0002] In the waterproofing treatment of self-healing concrete structures, the rolling and water removal process of waterproof membranes is crucial. However, traditional waterproofing devices have obvious deficiencies in terms of rolling compactness, water removal efficiency, and pressure roller adaptability, making it difficult to meet the strict requirements of modern engineering for waterproofing effects, construction efficiency, and cost control.

[0003] First, the tightness of the waterproof film's roll-up directly affects its waterproof performance. Traditional waterproof devices often lack an automatic adjustment mechanism during the roll-up process, resulting in uneven roll-up of the film, a large amount of air and moisture remaining inside, and reduced waterproofing effects. This not only increases the risk of concrete structures being damaged by water penetration, but also shortens the service life of the waterproof film.

[0004] Secondly, if the moisture on the surface of the waterproof film cannot be removed in time, it will accumulate during the rolling process and may penetrate into the concrete structure, posing a threat to the structural safety. Traditional water removal methods mostly rely on natural air drying or simple manual wiping, which are inefficient and difficult to guarantee water removal effects. Especially in an environment with high humidity, the moisture on the surface of the waterproof film is more difficult to remove quickly.

[0005] In addition, different engineering projects have different requirements for the width of the waterproof film and the length of the pressure roller. Traditional waterproof devices have limitations in the adaptability of the pressure roller, and cannot quickly and accurately replace pressure rollers of different lengths, which not only increases the difficulty and cost of construction, but also limits the versatility and flexibility of the waterproof device. For this reason, we provide a waterproof device for self-healing concrete structures. Summary of the invention

[0022] Compared with the prior art, the present invention provides a waterproof device for a self-healing concrete structure, which has the following beneficial effects:

[0023] 1. The waterproof device for self-healing concrete structure introduces an adaptive pressure-guiding structure. When rolling up the waterproof film, the device can automatically adjust the pressure of the upper pressure-guiding roller and the lower pressure-guiding roller according to the thickness of the film and the preset pressure range. This dynamic adjustment mechanism ensures that the waterproof film is compacted evenly and tightly during the rolling process, thereby significantly improving the compactness after rolling. The compact rolling not only reduces the residual air and moisture inside the film, but also enhances the fit between the film and the winding roller, further improving the waterproof effect. For the self-healing concrete structure, this means more lasting waterproof protection and reduces the risk of structural damage caused by moisture penetration.

[0024] 2. The waterproof device for self-healing concrete structure can remove moisture from the surface of the waterproof film synchronously during the winding process through water removal components, including a highly efficient water-absorbing sponge and an optimized water-squeezing linkage. The water-absorbing sponge adopts highly efficient water-absorbing materials such as nanofibers, which can quickly absorb moisture on the film, while the water-squeezing linkage uses hydraulic or pneumatic drive to accurately control the water squeezing time and force to ensure that the absorbed moisture is discharged at the appropriate time. This cycle of water absorption and squeezing not only improves the water removal efficiency, but also ensures the continuous water absorption capacity of the water-absorbing sponge, thereby achieving rapid drying of the surface of the waterproof film. This is of great significance for preventing moisture from accumulating and penetrating into the concrete structure during the winding process.

[0025] 3. The waterproof device for self-healing concrete structure is designed with an adjustable pressure-guiding structure so that it can easily adapt to and install upper and lower pressure-guiding rollers of different lengths. By adjusting the socket slider and socket plate in the mechanism and the reset action of the spring, the plug-in rod can automatically adapt and connect with the plug-in hole, so as to realize the fast and accurate replacement of pressure-guiding rollers of different lengths. This design not only simplifies the replacement process and reduces the difficulty of operation, but also greatly enhances the versatility and flexibility of the device. Whether facing waterproof films of different widths or adjusting the length of the pressure-guiding roller according to specific project requirements, the device can adapt quickly without complicated structural modification or customized production, thereby effectively reducing the use cost and time cost.

[0037] In the present invention, the U-shaped mounting seat 1 is made of high-strength alloy material, and is provided with a shaft rotating rod supported by precision bearings inside to ensure the stable rotation of the winding roller. At the same time, a shock-absorbing pad is added to the bottom of the mounting seat to reduce vibration and noise; the winding roller 2 is upgraded to an electric winding roller, with a built-in brushless DC motor, which is connected to the shaft rotating rod through a reducer and a coupling. The motor is driven by the controller according to a preset program or an external signal to realize the automatic winding and release of the waterproof film; the limit plate 14 adopts a magnetic suction design, which can be quickly installed and disassembled to ensure the stability of the waterproof film during the winding process and prevent the film from slipping off; the L-shaped plate 4 adopts an adjustable angle design and is fixed to the U-shaped mounting seat by a locking screw to adapt to different installation environments and the winding requirements of the waterproof film; the adaptive pressure guide structure adds a pressure sensor and an electric adjustment mechanism on the original basis.

[0044] The specific working process of the present invention is as follows: shaking the shaking handle 29 drives the winding roller 2 to rotate, thereby winding the waterproof film 3; when the waterproof film passes through the upper pressure-guiding roller 5 and the lower pressure-guiding roller 6, the waterproof film is pressed by the pressure-guiding structure to improve the compactness after winding; during the winding process, the waterproof film passes through the water-absorbing sponge 10, and the moisture on its surface is absorbed; as the winding roller rotates, the elliptical disk 17 intermittently touches the pressure-bearing part 16, and pushes the water-absorbing sponge to squeeze through the water-squeezing linkage to discharge the absorbed moisture; when it is necessary to replace the upper pressure-guiding roller 5 and the lower pressure-guiding roller 6 of different lengths, the socket slider 25 and the socket disk 26 in the adjustment mechanism are used, under the action of the spring 24, to achieve the adaptive connection between the plug-in rod 20 and the plug-in hole 21; the upper and lower buffer components between the rectangular through groove 18 and the sliding sleeve block 19, and the use of each spring, ensure the stability and buffering effect of the device during operation.
