QuebecGrouting pipe groutingWhat are the external factors affecting processing

When installing the Hainan grouting pipe, carefully check the embedded reinforcement in the groove before the joint is lowered. If cracks or breaks are found, remedial measures must be taken.

Green grouting materials mainly refer to industrial wastes such as fly ash slag and steel slag. It can be excited by alkali, and its solid particles are smaller than ordinary cement particles, and the particle gradation distribution is more reasonable. Therefore, it can be used as a raw material for grouting materials.

Quebec. The small editor of the grouting pipe reminds everyone that there should be no rust, water and other impurities when using the prestressed machinery. The working clip can be used after removing the foam in the packing box, and the grouting pipe should be properly kept. However, when the prestressed tendon is long and the grouting pipe needs to be tensioned repeatedly, it is suggested that a small amount of lubricant (e.g. anchor pulling spirit) be applied to the tapered hole of the anchor plate by the prestressed machine, which is not only conducive to the follow-up and anchor pulling of the working clip, but also conducive to the multiple grouting of the grouting pipe; Apply lubricant on the outer surface of the tool clip and the inner and outer surfaces of the taper hole of the anchor plate before use and regularly remove the debris on the clip surface to make the anchor flexible. However, it needs to be replaced and can not be used again.

Chemical grouting chemical grouting materials are mainly used in water glass and organic polymer grouting materials.

.Features of reusable grouting pipe: with one-way switch . Good anti blocking property and no backflow of slurry.

Compared with the sleeve valve pipe grouting method when the clip is cracked or the tooth surface is damaged, the common disadvantages of the grouting pipe grouting method, the flower pipe grouting method and the drill pipe grouting method are that the grouting is easy to overflow along the pipe wall and the grouting layering effect is poor. These disadvantages are particularly prominent when using the slurry with good fluidity and long initial setting time; Its advantages are simple equipment and process, good flexibility, fast construction speed, and more suitable for situations requiring rapid response.

Welcome calls . Slump test shall be carried out for concrete entering the site. No less than 3 groups of test pieces shall be made for the same batch of concrete with the same strength grade. One group is used for standard curing,Quebec22hollow composite anchor manufacturer, curing water and garbage from falling in. When necessary, a sump shall be set near the post cast strip of the base plate in combination with the design of the basement plane drainage system to facilitate the final cleaning before the grouting pipe is cast. When advance water stop is not used, a sump shall be set, which can be set in the basement according to the above method, or set outdoors as a temporary facility. Usually, we use the waterproof scheme between the grouting pipe and the water surface or before, and there are many methods for the grouting pipe to stop water in advance. It should be noted that the design unit should participate in the review of the construction organization design of the basement, so as to determine a complete implementation scheme of advanced water stop before the excavation of the foundation pit and the pouring of the cushion. Otherwise, the design modification requirements will be put forward only when problems are found in advance water stop during construction, which will affect the integrity and rationality of the whole water stop scheme.

Slump test shall be carried out for concrete entering the site. No less than 3 groups of test pieces shall be made for the same batch of concrete with the same strength grade. One group is used for standard curing, and the other two groups are used for curing under the same conditions to determine demoulding and allowable lifting time. It depends on what kind of syrup you inject. What kind of construction site. There are two kinds of general grouting pipe inner diameters 32 and 3 The diameter of the hole is 25-60mm at most. There are also about 100mm.

Quebec.[background technology] [0002] at present, some coal mines across the country use the grouting technology of coal seam floor aquifer to control water disasters, and have achieved obvious results. However, the grouting pipe after grouting exceeds the exposed part of the roadway floor and has different lengths. Most mines adopt mechanized coal mining technology, and hydraulic support and scraper conveyor need flat floor. At present, the mine still uses a hacksaw to manually cut the underground grouting pipes. It needs to clear some of the grouting pipes exposed from the roadway floor, which is time-consuming, each person cuts I grouting pipes every 2 hours.

● features: the grouting pipe is divided into disposable grouting pipe (ccll-y grouting pipe, qdm-it grouting pipe, ccll-y full section grouting pipe) and repetitive grouting pipe (ccll-d grouting pipe, ccll-d full section grouting pipe)

The construction steps of the three grouting methods are basically the same: the lower pipe grouting pipe grouting method and the flower pipe grouting method generally use the vibration method to place the grouting pipe into the soil at a predetermined depth. In the case of a large depth, the method of pre drilling a certain depth and then vibrating in can also be used. The drill pipe grouting method directly relies on the drilling method to place the grouting pipe (drill pipe) into the soil.
