Abstract
The invention discloses a wet-type concrete spraying process and belongs to concrete spraying processes. According to the wet-type concrete spraying process, cement and gravel are conveyed to a spray gun respectively in two branches; after the gravel and a powdery accelerating agent are proportionally mixed and stirred through a stirring mechanism, one branch enters a conveying mechanism, and the gravel is conveyed to the spray gun; after the cement and water are proportionally mixed and stirred through a mixing and stirring mechanism, the other branch is conveyed to the spray gun through a grout conveying pump; after being mixed in the spray gun, the two branches are sprayed to a spray-receiving face through the spray gun. According to the technical scheme, the process can achieve the purposes of falling dust and being slight in springback, change the status quo that a liquid accelerating agent must be used in a traditional wet spraying process, reduce additive cost in wet spraying construction, and guarantee material conveying distances. The process can be widely applied to grout spraying construction in the various industries of coal mine, water and electricity, tunnels, municipal engineering and the like.
Description
Technical field
The present invention relates to a kind of concrete spray technology, specifically a kind of Wet-type concrete spray technology.
Background technology
At present, concrete sprayer both domestic and external is divided into dry spraying machine, and watering jet eductor and wet-spraying machine because dry spraying machine and watering jet eductor dust when the spraying operation is large, resilience is many, jet quality is poor, thereby are replaced by wet-spraying machine gradually.Screw pump structure in wet-spraying machine and squash type structure, be only applicable to carry without the mortar of aggregate, cannot carry the concrete that contains aggregate; Cylinder Plunger formula wet-spraying machine, volume is larger, transportation inconvenience, hydraulic system maintenance is complicated, and price is higher.Rator type concrete wet blasting machine material adds water and stirs rear resistance increasing, and fed distance is shorter.
Summary of the invention
The invention provides a kind of new Wet-type concrete spray technology, the dust concentration while adopting this technique can reduce construction, reduces material resilience, saves material, can adopt powder accelerator to carry out wet shot, has reduced additive expense.Be easy to apply in various spray operations.
The present invention is a kind of Wet-type concrete spray technology of realizing with following technical scheme, divide two-way to be delivered to respectively spray gun cement and sandstone, the rabbling mechanism of wherein leading up in proportion after mix and blend, enters sandstone and powder accelerator conveying mechanism sandstone is transported to spray gun; Another road in proportion after mix and blend mechanism mix and blend, is transported to spray gun by pump for mortar transmission by cement and water, and two-way is sprayed to and is subject to spray plane by spray gun after mixing in spray gun.
Adopt technique scheme, the technique of this invention can reach the object of depositing dust, less resilience, has changed the present situation that conventional wet pressure spray process must adopt liquid accelerator, and additive expense while having lowered wet shot construction has guaranteed the fed distance of material simultaneously.The present invention can be widely used in the multiple industry shotcrete constructions such as colliery, water power, tunnel, municipal administration.
The invention has the beneficial effects as follows, the dust concentration while reducing operation, has improved work situation, avoids the harm of occupational disease, reduced labour intensity, be convenient to mobile, take up room littlely, feeding is continuous, is easy to safeguard, saves material, reduces costs.
