Description

Technical Field

[0001] The utility model belongs to the technical field of concrete curing, and in particular relates to a steam curing heating ring. Background Art

[0002] Concrete is widely used in construction and road construction. Concrete curing is a key step to ensure that concrete reaches the expected strength and durability. Traditional concrete curing methods include water curing, steam curing, etc. Although water curing is low in cost, it has a long curing cycle and is not effective under low temperature conditions. Steam curing can accelerate the improvement of concrete strength and shorten the curing time, but traditional steam curing equipment is often bulky and inconvenient to use in narrow or special conditions, such as concrete curing around manhole covers.

[0003] In urban construction and maintenance, the maintenance of concrete around manhole covers is particularly important. The concrete in these parts is often difficult to achieve ideal maintenance effects due to construction environment restrictions or insufficient maintenance conditions. Therefore, there is a need to develop a device suitable for the maintenance of concrete around manhole covers, which should be able to provide an effective and fast maintenance method without relying on large-scale maintenance facilities.

[0004] In the existing technology, the concrete curing method still has the following shortcomings: first, the curing efficiency of the traditional curing method is low, especially in low temperature environment, the concrete strength is slowly improved, which prolongs the construction period; second, the existing steam curing equipment is large in size and is not suitable for curing in narrow spaces or special conditions, such as curing concrete around manhole covers; third, there is a lack of a curing equipment that can quickly improve the strength of concrete and is easy to operate on site. Therefore, there is an urgent need for a new type of curing equipment to solve the above problems, especially for the curing of concrete around manhole covers in urban infrastructure.

[0013] Furthermore, a second through hole is formed through the upper end surface of the isolation ring. The second through holes are distributed at equal intervals around the central axis of the isolation ring, and the second through holes correspond to the exhaust pipe.

[0014] Furthermore, a heat-conducting member is fixedly connected to the bottom of the water storage tray. The heat-conducting member is arranged through the bottom of the water storage tray and is spiral-shaped.

[0015] Furthermore, a positioning groove is provided at the bottom edge of the water storage tray, and the positioning groove is inserted into the inner side of the top of the outer ring.

[0022] Improved safety and environmental protection: The device ensures the supply of oxygen required for combustion during the heating process through the design of the air intake slot, thereby optimizing the combustion efficiency and reducing the emission of harmful gases. In addition, the design of the entire equipment takes into account the effective use and control of thermal energy, reduces energy waste, and meets current environmental protection requirements.

[0023] A special heating ring is used for heating. Since a large amount of water vapor will be generated due to the heating inside the heating ring, the steel fiber concrete in the coverage area is steam cured and insulated, so that the steel fiber concrete can quickly reach strength.
