Description

Technical Field

[0001] This utility model relates to the field of marine engineering large-volume concrete curing technology, specifically a curing device suitable for marine engineering large-volume concrete. Background Technology

[0002] Mass concrete refers to large-volume concrete structures with a minimum geometric dimension of 1 meter, or concrete that is expected to develop harmful cracks due to temperature changes and shrinkage caused by the hydration of cementitious materials. Offshore mass concrete refers to large-volume concrete used in marine engineering projects. After pouring, offshore mass concrete should be promptly covered with moisture-retaining materials such as plastic film, burlap sacks, or straw mats, and water should be sprayed onto the concrete surface to keep it constantly moist and reduce its temperature, thus preventing cracking. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a curing device suitable for large-volume concrete in marine engineering, addressing the above-mentioned shortcomings.

[0004] To solve the above technical problems, the present invention adopts the following technical solution:

[0005] A curing device suitable for large-volume concrete in marine engineering includes multiple interlocking templates, a curing curtain, a support plate, and a water supply component. The templates can be assembled into a complete rectangular frame, within which the concrete to be cured is placed. Each template has a hollow inner side and openable left and right sides. A support plate is horizontally positioned on the inner side of each template. Fitting flanges are vertically positioned on both the left and right sides of each template. Connecting holes are present on the top and bottom sides of each template. Two adjacent templates on the left and right sides are joined together by the fitting flanges and fixed to each other with bolts. Two adjacent templates on the top and bottom sides are fixed to each other with bolts passing through the connecting holes. Mounting holes are provided in the center of the upper surface of each template. A water supply component is installed in the mounting hole of the uppermost template of the rectangular frame to supply water to the upper surface of the concrete to be cured within the rectangular frame. The output end of the water supply component extends to the top of the template and is positioned above the concrete to be cured. A curing curtain is installed at the output end of the water supply component to cover the upper surface of the concrete to be cured.

[0006] Furthermore, a permeable plate is provided on the inner side of the template.

[0007] Furthermore, the outer side of the template is provided with a support base for cooperating with an external support rod, and the external support rod is inclined and used to support the support plate.

[0008] Furthermore, the water supply assembly includes a main water supply pipe, branch water supply pipes, and an installation plate. The main water supply pipe is laid along the upper surface of the support plate of all the uppermost templates. The branch water supply pipes are installed on the uppermost templates. The input end of each branch water supply pipe is connected to the main water supply pipe. An installation plate is provided on the outside of the branch water supply pipe for fixing the branch water supply pipe in conjunction with the installation hole.

[0009] Furthermore, the maintenance curtain includes a water-conducting layer, a wear-resistant layer, and a sun-shading layer. The input end of the water-conducting layer is used to connect with the output end of the water-conducting branch pipe. The water-conducting layer is made of two layers of waterproof fabric bonded together. The two layers of waterproof fabric are bonded to each other and form multiple interconnected cavity pipes on the inside. The multiple cavity pipes form a water-conducting network. The lower waterproof fabric is provided with multiple drainage holes connected to the water-conducting network. Copper rings are provided on the inner side of each drainage hole on the lower waterproof fabric. The outer side of the water-conducting layer is covered with a wear-resistant layer. A sun-shading layer is provided on the upper surface of the wear-resistant layer. A skirt is provided around the outer perimeter of the wear-resistant layer. The maintenance curtain is rectangular in shape.

[0010] Furthermore, a drain outlet is provided on the side of the water supply layer away from the input end, and a plug is threadedly connected to the drain outlet. The drain outlet is used to quickly drain the water accumulated in the water supply network.

[0011] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages:

[0012] This invention utilizes a template with a water-conduit assembly and a curing curtain. The water-conduit assembly supplies water to the curing curtain to wet the concrete surface. The moisture on the concrete surface can then permeate downwards through a permeable plate, keeping the concrete facade moist. This effectively ensures surface moisture and reduces concrete temperature, preventing cracking. The curing curtain, especially the water-conduit layer with a water-conduit network and a wear-resistant layer, can retain moisture while protecting and reducing wear on the curtain. The shading layer further reduces concrete temperature. The diamond-shaped grid of the water-conduit network facilitates water flow and cleaning. The curing curtain, with its overlapping skirts, effectively covers the concrete surface, reducing moisture evaporation.

[0013] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Attached Figure Description
