Embodiments of the present invention are written in a progressive manner.
Example one
As shown in fig. 1 to 4, a foam concrete curing apparatus includes: a container 1; the geomembrane elastic winding and unwinding roll 2 is positioned in the container 1 and is used for providing a geomembrane 21 for covering foam concrete; an opening end 11 for leading out one end of the geomembrane 21 is arranged below the middle part of the container 1; and the positioning rod 3 is used for fixing one end of the geomembrane 21 led out from the container 1, so that the led-out geomembrane covers the surface of the foam concrete.
In the invention, the geomembrane 21 is arranged in the container 1, so that the geomembrane 21 which does not participate in maintenance can be stored for secondary use, in the using process, the container 1 can be firstly fixed, the geomembrane 21 is pulled out from the container 1 for use in a mode of translating the positioning rod 3, the surface of the foam concrete is covered, and the water in the foam concrete can be prevented from volatilizing to the space through the water-resisting property of the geomembrane 21, so that the surface cracks of the foam concrete can be effectively reduced, and the strength of the foam concrete can be improved.
In specific implementation, a supporting structure can be arranged at the bottom of the container 1 to support the container, and a support structure can be adopted to ensure the stability and reliability of the container in the using process, and because the geomembrane 21 is flattened by applying a pulling force in the using process, a support rod with a pointed end part is preferably arranged at the bottom of the support structure and is inserted into the ground, so that the position of the container 1 can be prevented from moving in the process of applying the pulling force to the geomembrane 21. The same positioning rods 3 can be fixed in the above manner after the geomembrane 21 is stretched in place, so as to ensure the stability of the tension of the geomembrane 21.
In order to ensure the flatness of the geomembrane 21 during use, it is preferable to cover the positioning rods 3 over the entire range of the edge of the geomembrane 21, thereby preventing wrinkles from occurring.
Preferably, the geomembrane elastic rolling and unrolling roll 2 comprises a fixed shaft 22 positioned in the container and a spring piece 23 wound on the fixed shaft 22, wherein the spring piece 23 is used for providing rolling elasticity for the geomembrane 21. Through the setting of spring leaf 23 for geomembrane 21's rolling has elasticity self-driving nature, only needs to remove the fixed to locating lever 3 promptly, and is close to it to container 1, can realize its automatic rolling, until locating lever 3 and container 1 laminating back, can accomodate the two simultaneously. The spring piece 23 can be connected with one end of the geomembrane 21 through the connecting piece, the connection reliability needs to be ensured, and after connection, the spring piece only needs to be wound layer by layer.
In a specific construction, since partial evaporation of moisture may occur already on the surface of the foam concrete during the course of laying the geomembrane 21, it is preferable that the water inlet 12 is provided above the middle of the container 1 for injecting moisture into the container 1. Through the provision of moisture, the geomembrane 21 has certain humidity when being led out from the container 1, and a small amount of moisture on the surface opposite to the foam concrete can supplement the volatile moisture in a small amount, so that the maintenance of the foam concrete obtains better effect, wherein a proper sealing structure is required to be arranged at the opening end 11, and particularly, an elastic structure for extruding the geomembrane 21 can be selected, so that the leakage of the moisture is avoided.
In order to optimize the technical effect, the geomembrane 21 is provided with two layers, wherein one layer far away from the surface of the foam concrete is of a complete structure, and a plurality of hole sites are arranged on one layer close to the surface of the foam concrete and used for allowing moisture between the two layers of the geomembrane 21 to be transferred to the surface of the foam concrete. Through superstructure's setting, aim at realizes better evaporation separation and moisture supply, at the in-process that geomembrane 21 was drawn forth from container 1, must can persist certain moisture between two-layer geomembrane 21, and above-mentioned moisture can avoid volatilizing under upper geomembrane 21's separation on the one hand, and on the other hand can reach the concrete surface and carry out the maintenance through the hole site that is located on bottom geomembrane 21 at the in-process of maintenance.
In the above embodiment, in order to reduce the moisture leakage in the container 1, the height of the gap at the opening end 11 should be reduced as much as possible, and it is only necessary to ensure that the geomembrane 21 can be normally led out, so as to avoid the moisture leakage during the maintenance process, of course, because of the outdoor construction, the proper moisture leakage is within the allowable range, and at the same time, the moisture can be discharged after the geomembrane 21 is led out in place.
Example two
In the above embodiment, the moisture supply method for one time is mainly adopted in the technical direction of increasing the moisture content of the geomembrane 21, that is, the maintenance method of the foam concrete is optimized by the moisture once brought out after being led out from the container 1.
In this embodiment, unlike in the first embodiment, the moisture is continuously supplied to cover the geomembrane 21 for a desired period of time in the entire cycle. Specifically, as shown in fig. 5 to 7, two sides of the inner wall of the container 1 in the height direction of the gap of the open end 11 are respectively provided with a separation structure 4 for supporting two layers of geomembranes 21, in this embodiment, it is also necessary to reduce the height of the gap of the open end 11 as much as possible, the separation structure 4 is used for separating the two layers of geomembranes 21 and supporting and guiding the two layers of geomembranes, the two layers of geomembranes 21 are respectively attached to four sides in the height direction and the width direction of the open end 11 under the restriction of the two separation structures 4, and a sealing structure is formed by the attachment, wherein the attachment penetrates through the width direction of the entire geomembrane 21 and the height direction of the open end 11, so that the leakage amount of moisture is small, but the above-mentioned structure can allow appropriate expansion between the two layers of geomembranes 21, and can also play a role in guiding moisture even in, due to the existence of the gravity of the moisture, the water pressure can enable the moisture to flow between the two geomembranes 21, the flowing speed is related to the height of the gap of the opening end 11 and the height of the moisture in the container 1, certain leakage can be formed at the edges of two sides of the geomembrane 21 in the moisture flowing process, the purpose of the invention is not affected, and the solution to the problems can be carried out by the following scheme: in the processing process of the geomembrane 21, the two sides can form relatively good sealing effect after being attached by properly increasing the thickness of the edge, the specific thickness can be uniformly increased, and protrusions similar to a pattern structure can also be adopted.
The preferred scheme can realize continuous supply of water, and the specific working principle is as follows:
two-layer geomembrane 21 is laminated respectively on two separation structure 4 to make it form certain angle and laminate with forming between the gap height direction of open end 11 both sides reason, of course, the width direction both sides reason of open end 11 is laminated with the edge of geomembrane 21 this moment equally, consequently make the region between two-layer geomembrane 21 become the main circulation region of moisture, moisture can extend to the direction of drawing forth between two-layer geomembrane 21 under the effect of gravity, fall to the replenishment of moisture on the foam concrete surface when reaching the hole site that is located bottom geomembrane 21, because the flow area of hole site is less in the width direction, consequently unnecessary moisture can continue to extend forward and reach the full scope of coverage. The moisture can be retained to the maximum extent under the blocking of the upper geomembrane 21, the maintenance effect is effectively ensured, wherein the size of the hole site can be specifically set according to the actual requirement.
In this embodiment, in order to obtain a more uniform curing effect, two optimized forms of hole sites are provided:
A. the hole sites are uniformly distributed in the width direction of the geomembrane 21, and after the geomembrane 21 is led out, the density of the hole sites is gradually increased in the direction far away from the opening end 11, so that more flowing-out space is provided for the moisture with lower pressure at the tail end;
B. the holes are uniformly distributed in the width direction of the geomembrane 21, and after the geomembrane 21 is led out, the sectional area of the holes is gradually increased in the direction far away from the opening end 11, so that the same technical effect as the above can be realized.
Preferably, the separation structure 4 includes two parts symmetrically arranged along the width direction of the geomembrane 21, in order to ensure the full coverage of the concrete, the width of the geomembrane 21 is generally wide, which brings challenges to the processing and stability of the separation structure 4, and in order to reduce the above difficulty, the separation structure is designed in a split manner, so that even if only the local positions of the two edges of the geomembrane 21 are supported, the purpose of the present invention can be achieved.
In order to reduce the friction between the geomembrane 21 and the separation structure 4, each part of the separation structure 4 is a roller structure with one fixed end, and rolling instead of sliding can achieve better guiding effect.
Preferably, in order to further ensure the uniqueness of the moisture communication channel and enable moisture to quantitatively flow to a required position as much as possible to avoid excessive leakage, a pressing strip 5 for pressing the geomembrane 21 is arranged between the separation structure and the joint, and two ends of the pressing strip 5 are fixedly connected with the inner wall of the container 1.
Referring to fig. 8, the fitting part in this embodiment can achieve better sealing through the arrangement of the pressing strip 5, but since the pressing strip 5 needs to cover the full width of the geomembrane 21, the problem of unreliable pressing at the middle position is inevitable, and therefore, the problem can be overcome by appropriately increasing the thickness of the middle part, wherein the increase in thickness can be achieved through integrated processing, as shown in fig. 9 (only for illustration, the actual structural proportion is adjusted), or can be achieved through subsequent installation of the extruded block-shaped structure, as shown in fig. 10 (only for illustration, the actual structural proportion is adjusted).
In this embodiment, in order to reduce the difficulty of the production and processing of the whole container 1, referring to fig. 7, on the barrel-shaped structure of the container 1, the parts for installing the separating structure 4, the open end 11 and the pressing strip 5 are independently arranged, and a sealing and fixing structure is arranged between the barrel-shaped structure and the main body part of the container 1, so that the whole container can be processed in a split manner, and the installation and processing efficiency is improved, wherein the fixing structure can adopt a conventional connecting piece to connect the overlapping parts of the main body part and the independent parts, and the sealing structure can be a sealing strip structure clamped in the middle of the overlapping parts.
It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed.
