During the grouting process, various accessories, such as steel pipes, that are stained with mud must be promptly cleaned. After the completion of grouting, the entire equipment shall be cleaned, especially the main equipments such as grouting pump, mixer and vacuum pump must be thoroughly cleaned with clean water; the construction site of the grouting is relatively messy and must be cleaned in time. Ensuring the cleanliness of construction equipment is an important indicator of equipment maintenance, and “work completion and cleanliness†is also one of the requirements for civilized construction.
The operation team is a key factor in the entire construction process. At the same time, it is necessary to cultivate the workers' skills and establish the responsibility of the workers so that they can face the importance of construction. In order to solve the on-site technical problems and prevent irregular operations, timely supervision and guidance by on-site management personnel is also essential in construction.
Common problems in grouting construction treatment (1) Leakage of the beam body. Method one: When the bottom hole leakage, buy "plugging agent" plugging, this method is simple, convenient, fast and practical. Method 2: Attach double-sided tape around the rubber pad or other rigid plate (the area is determined according to the condition of leakage but not too large), buckle at the location of leakage, use the small jack to fasten the object, so that the slurry flow In the sealed space of manufacture, normal construction is then performed and the grout can be removed after the initial setting. (2) The web leaks. Method One: Use "Loop Stopper." Method 2: Because the leaks in the inner and outer webs of the web are generally leaky pulp, they can be plugged with something like a rag or sponge. Because there are no reference objects inside and outside, only artificial blockage can be used. Then it works normally until the cement is set and then withdrawn. (3) Hole string slurry. It is not possible to predict whether there is a string hole in the beam hole before construction, but the adjacent holes are generated in the string. If there are two adjacent holes in the string, the two holes in the vacuum are evacuated together. When the slurry is grouted, one hole is used for construction. However, actually two holes are grouted together. If only a few sets of steel pipes and ball valves are prepared, pressure will be prepared. The adjacent several channels of the slurry channel can also be closed. Even if the channel string slurry can be constructed as usual, the operation is exactly the same without affecting the construction quality, but the grouting time of the hole will be longer. (4) Equipment failure. Maintaining equipment is the only way to reduce equipment failures. However, when the equipment in construction is faulty due to an operation error or a device in the machinery fails to function properly, special equipment must be inspected and repaired. In particular, if there is any remaining slurry or the hole is not filled, check the equipment in time. Failure to make the appropriate judgments.
