近年來，建築修繕領域不斷出現新技術，其中高壓灌注、化學錨栓、無收縮灌注、AC柏油切割和RC切割等技術被廣泛應用。高壓灌注是一種將混凝土通過高壓泵灌注到結構中的方法，可以提高結構的強度和耐久性。化學錨栓則是一種將金屬錨栓固定在混凝土中的方法，可以有效地固定結構件。無收縮灌注則是一種不會產生收縮應力的灌注方法，可以減少結構的裂縫。AC柏油切割和RC切割則是在建築中常見的切割方法，可以用來開口、切割和拆除結構物。
這些新技術的應用使得建築修繕工作更加高效和精確。例如，在進行牆壁打針時，可以使用高壓灌注技術來加固結構，提高牆壁的承重能力。在進行門窗切割時，可以使用AC柏油切割和RC切割技術來精確地開口，保證施工的準確性。在進行瓦斯孔的開鑿時，可以使用化學錨栓來固定管道，確保安全性。
總的來說，這些新技術的應用為建築修繕工作帶來了許多便利和效益，同時也提高了施工的質量和安全性。

Title: Application of New Technologies in Building Repairs
Article: In recent years, new technologies have emerged in the field of building repairs, including high-pressure grouting, chemical anchor bolts, non-shrink grouting, AC asphalt cutting, and RC cutting. High-pressure grouting is a method of pumping concrete into structures under high pressure, which can improve the strength and durability of the structure. Chemical anchor bolts are a method of fixing metal anchor bolts in concrete, which can effectively secure structural components. Non-shrink grouting is a method of grouting that does not produce shrinkage stress, reducing the likelihood of cracks in the structure. AC asphalt cutting and RC cutting are common cutting methods in construction, used for opening, cutting, and demolishing structures.
The application of these new technologies has made building repair work more efficient and precise. For example, when performing wall stitching, high-pressure grouting can be used to reinforce the structure and increase the load-bearing capacity of the wall. When cutting doors and windows, AC asphalt cutting and RC cutting can be used to accurately open the structure, ensuring construction accuracy. When drilling gas holes, chemical anchor bolts can be used to secure pipes, ensuring safety.
Overall, the application of these new technologies has brought many conveniences and benefits to building repair work, while also improving the quality and safety of construction.
