What should I do if there are cracks in the Beret film

After a certain age, everything will break, including the Beret film. But did you know that once a crack appears on the Beret, it is a very dangerous omen! So, is there any way to prevent cracks from appearing on the Beret piece? Of course, the answer is yes. Once a crack appears, it will greatly reduce the service life of the Beret piece. Therefore, it is necessary to pay attention to maintenance and actively repair it after the crack appears to avoid causing greater impact.

So what do we need to do to prevent the Beret from breaking?

It is more important to strengthen the initial curing of concrete first. After the concrete pouring of the Bailey slab is completed, the exposed profiles should be covered with straw mats, straw bags or plastic films in a timely manner, and moistened with water for curing. In high temperature, low humidity, and high wind speed weather, it is necessary to cover and sprinkle water for maintenance as soon as possible, and appropriately postpone the maintenance time. To avoid temperature cracks caused by internal bonding of concrete, it is generally recommended to control the temperature difference between the concrete profile and the outside or inside to be less than 25 ℃. The usual control method is to slowly raise and lower the temperature of the heated and solidified components, so that the temperature does not exceed 10 ℃/h, and it is hoped that the cover plate and demolding are slow to avoid excessive temperature stress; For large volume structures, insulation and curing should be carried out when the temperature difference between concrete and the outside is large. When the director removes the template, the temperature difference should be controlled within 25 ℃.

After the template is removed, the temperature difference should be controlled within 25 ℃ to ensure that the surface is not excessively oxidized.

Reasonably set up construction joints, pour Bailey panels at appropriate positions, and accelerate heat dissipation; In the construction of mass concrete on the rock foundation or thick concrete cushion, a sliding layer (horizontal asphalt mortar, sanding or rolling) shall be laid on the cushion, and a buffer layer (polyethylene foam) shall be placed on the vertical side to eliminate the embedding effect and release the bonding stress. Select well graded coarse aggregates and strictly control the clay content. Strengthen concrete vibration, improve concrete strength and tensile strength. Increase the required temperature on the basis of the setting; Increase the reinforcement ratio of nodes, set hidden beams, reduce edge effects, and improve tensile strength. At the same time, the early curing of concrete has been improved, and the initial tensile strength and elastic modulus of concrete have been enhanced.

Beilei Pian is an indispensable auxiliary tool for bridge construction. The invention of Bailey film made bridge construction more convenient and efficient, and due to the construction of bridges, communication between the two banks of rivers became more frequent.

Beilei tablets have the characteristics of simple structure, convenient transportation, fast installation, high load-bearing capacity, good interchangeability, and strong adaptability.
