Abstract
The utility model relates to a kind of spray concrete device, particularly concrete ejecting device is sprayed in a kind of underground mining temporary lining, comprise into concrete pipe, enter the middle part that concrete pipe connects baffle-box one side, baffle-box opposite side is symmetrical arranged nozzle, and nozzle all tilts to baffle-box middle part, and the injection direction of nozzle is intersected in a bit, the spout of nozzle is oblate, improves efficiency of construction.
Description
Technical field
The utility model relates to a kind of spray concrete device, particularly a kind of underground mining temporary lining spray concrete ejecting device.
Background technology
Spray concrete, also claims sprayed mortar, is with the construction method of Spray Gun Of The Pressure spraying placing pea gravel concreten, is usually used in thin wall construction or the lining of other structures and the toppings of steel work such as placing tunnel liner, wall, ceiling.Appropriate to the occasion using with the way of mixing with spray, to reduce consistency change is used for constructing.The jet velocity of this method is lower, and because water/binder ratio increases, concrete early strength is also lower, but bounce situations makes moderate progress, and material fit is easy to control, and operating efficiency be height compared with dry mixing method.Admixture by the cement preparing in advance, sand, stone, water and some, packs spraying machine into, after utilizing pressure-air to be sent to shower nozzle and accelerating admixture to mix, with very high speed, sprays to rock or concrete surface and forms.Existing spouting plant mostly is point type whitewashing, and it is circular that nozzle mostly is, and projected area is little, and spray site is concentrated, and screen resilience is large, and construction quality is low, and construction risk is high.
Utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: a kind of underground mining temporary lining spray concrete ejecting device that improves efficiency of construction is provided.
Underground mining temporary lining spray concrete ejecting device described in the utility model, comprises into concrete pipe, enters the middle part that concrete pipe connects baffle-box one side, baffle-box opposite side is symmetrical arranged nozzle, nozzle all tilts to baffle-box middle part, and the injection direction of nozzle is intersected in a bit, and the spout of nozzle is oblate.
Operating principle and process:
During work, concrete grout enters baffle-box from entering concrete pipe, after being filled up, baffle-box goes out from nozzle ejection, two nozzle spouts are oblate, spray regime is that line formula is sprayed, reduced rebound degree, because nozzle all tilts to baffle-box middle part, the injection direction of nozzle is intersected in a bit, the concrete particle that splash is got up is ejected concrete grout post and absorbs, simultaneously, existence due to baffle-box, from entering the kinetic energy of the concrete grout that concrete pipe enters, greatly weakened, make from nozzle ejection mode gentleer, greatly reduced rebound degree, improved efficiency of construction, guaranteed personal safety.
The beneficial effect that the utility model compared with prior art had is:
Underground mining temporary lining spray concrete ejecting device described in the utility model, two nozzle spouts are oblate, spray regime is that line formula is sprayed, reduced rebound degree, because nozzle all tilts to baffle-box middle part, the injection direction of nozzle is intersected in a bit, the concrete particle that splash is got up is ejected concrete grout post and absorbs, meanwhile, due to the existence of baffle-box, from entering the kinetic energy of the concrete grout that concrete pipe enters, greatly weakened, make from nozzle ejection mode gentleer, greatly reduce rebound degree, improved efficiency of construction, guaranteed personal safety.
Accompanying drawing explanation
Fig. 1 is the utility model embodiment schematic diagram.
In figure: 1, nozzle; 2, baffle-box; 3, enter concrete pipe.
The specific embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
As shown in Figure 1, underground mining temporary lining spray concrete ejecting device described in the utility model, comprise into concrete pipe 3, enter the middle part that concrete pipe 3 connects baffle-box 2 one sides, baffle-box 2 opposite sides are symmetrical arranged nozzle 1, nozzle 1 all tilts to baffle-box 2 middle parts, and the injection direction of nozzle 1 is intersected in a bit, and the spout of nozzle 1 is oblate.
Operating principle and process:
During work, concrete grout enters baffle-box 2 from entering concrete pipe 3, after being filled up, baffle-box 2 ejects from nozzle 1, two nozzle 1 spouts are oblate, spray regime is that line formula is sprayed, reduced rebound degree, because nozzle 1 all tilts to baffle-box 2 middle parts, the injection direction of nozzle 1 is intersected in a bit, the concrete particle that splash is got up is ejected concrete grout post and absorbs, simultaneously, existence due to baffle-box 2, from entering the kinetic energy of the concrete grout that concrete pipe 3 enters, greatly weakened, make from nozzle 1 spray regime gentleer, greatly reduced rebound degree, improved efficiency of construction, guaranteed personal safety.
