Description

Technical Field

[0001] The utility model relates to the technical field of wall maintenance, in particular to a wall maintenance bag. Background Art

[0002] When pouring flexible formwork concrete for gob-side entry retaining in coal mines, ordinary portland cement with relatively high heat of hydration is usually used. During the hydration process of concrete, a large amount of heat is released. Although the surface of the concrete in contact with the air can dissipate heat to a certain extent, the transfer of internal heat is relatively difficult, resulting in an obvious temperature difference between the inside and outside of the concrete. When the temperature difference exceeds 20 degrees Celsius, stress will occur inside the concrete, leading to a shrinkage difference between the surface and the inside, thus forming cracks and ultimately causing the concrete to crack. In addition, the hydration process of concrete consumes water. Due to the large volume of the flexible formwork wall of the concrete poured underground in coal mines, it is difficult for the internal concrete to absorb enough water from the external air for the hydration reaction, resulting in insufficient internal hydration and a large difference in strength between the inside and outside of the concrete. Under the long-term load, the concrete wall may creep, further exacerbating the structural deformation. These problems seriously affect the performance and safety of the concrete, so improvement is urgently needed. Content of the Utility Model
