FuckGrid maintenanceMore than 20 years ago, there were more than 300 projects. The chimney crack repair works look like a little work, so they know how many doors. The location, width and causes of the cracks are completely different, and the error is a waste of money, while the weight will be broken again in the coming year. I will tell you today about the pits i've stepped on and the lessons i've learned。
How do you fix the chimney crack
Don't put cement on it as soon as you see it. That's the worst way to do it. I did repairs at a power plant in jiangsu in 1919, and they had to put an ordinary sand solution on them, and then open it three months later, and this time it was leaking from inside, the steel walls were corrupted, and the whole steel plate had to be replacedIt cost 400 grandI don't know. The correct process is to conduct a crack detection, using an instrument to measure width, depth, direction, and to determine whether the temperature stresses, depositions or concrete contractions are caused before a programme can be established。
In the programme, low-cost, short-duration epoxy epoxy injection in shallow cracks is sufficient, with two or three people able to finish three days. But if the cracks are more than zero, three millimeters across the inner wall, or if they're on the inner barrel of the chimney, the light can't fill it upSteel plate reinforced or carbon fibre entangledI don't know. I've got a project in my hands, where three steel cylinders are broken at the top of the chimney, and i'm finally pulling them to 19 days with a hot plate of zinc and a bolt, but once and for all, no more problems。
How much for a chimney crack
I can answer that question 20 times a day. Honestly, no price. A 1 mm shallow suture in which the material is added to manual capacity is 2 300 metres; if the same suture passes through the inner wall, it will be a few thousand times more. Steel chimneys are more expensive than concrete chimneys and above 60 metres in height are high-altitude operating platforms, with all the costs of safety and lifting, and the total price is two to three times higher. I usually report rooms to clients so that they can count on the results of actual surveys。
There is also a hidden formation that can easily be ignored — the loss of production. Last month, at a chemical plant in shandong, the chimneys had to be shut down for four days, and more than a million people lost their production line alone. And then we adjusted the construction programme to cross-practiceIt's a day and a halfThe client saved more than 800,000. Therefore, the selection team should not simply look at the low price, depending on whether the duration of the work and the impact of the shutdown can be calculated。
The crack, the little stitch, the big hole, the big hole, the security hazard. Regular inspections and timely disposal are far more cost-effective than after-action repairs. A friend with a problem can measure the width of the cracks with a plugOver zero three millimeters, stop draggingI don't know。
