Abstract
Rotatory wet blasting of dry shotcreting adds water installation, this buffer of the device include guide slide, buffering sleeve, inlet valve, and inlet valve includes an inlet valve, the 2nd inlet valve, and the both ends of buffering sleeve are equipped with feed inlet, discharge gate respectively, guide slide sets up in the buffering sleeve, inlet valve sets up the peripheral circumference at the buffering sleeve. Guide slide is the broken line form, and guide slide is divided into three segment structures first broken line section, second broken line section, third broken line section promptly, and an inlet valve sets up in first broken line section and the crossing buffering sleeve circumference department of second broken line section, the 2nd inlet valve sets up in second broken line section and the crossing buffering sleeve circumference department of third broken line section. The utility model discloses a buffer can change shotcrete's movement track, makes its simple linear motion become rotatory circular motion, simultaneously, making it have and becoming parallelly to adding water originally perpendicularly to adding water, the water of being convenient for fuses with shotcrete better.
Description
Technical field
The utility model is that dry shotcrete rotates wet spray priming apparatus, is applicable to on-the-spot dry shotcrete nozzle termination and adds this device, arrives the object of wet spray.
Background technology
Sprayed concrete is one of important method of concrete construction, there is the advantages such as flexible, quick and economic, it is mainly used in underground structrue engineering, such as the lining cutting etc. of the supporting of vertical shaft for mine, gallery, tunnel and large-scale culvert, and the engineering such as highway, railway, also work China Democratic National Construction Association it was applied in recent years, such as foundation pit stope support, the reinforcing of building structure and repairing etc.
Sprayed concrete is directly injected to by concrete batching system on construction working face, it is possible to without template or few template, saves mould material, and saves Zhi Mo, striking time, is conducive to shortening the duration. At present, the application of sprayed concrete is more and more extensive, but also there is very big problem, one when being construction owing to after strong jetting action makes concrete strike construction surface, part concrete is fallen underground by bounce-back, causes the significant wastage of material; Two is that sprayed construction is on-the-spot, and dust concentration is excessive, and execution conditions are severe.
Dry shotcreting method is the injection method developed the earliest, apply more extensive, dry shotcreting method is after cement sand, stone are mixed into dry mixing material by a certain percentage, with forced action type amalgamator uniform mixing, throw again people in spraying machine by compressed air delivery to nozzle, after nozzle place adds the mixing of people's water, with certain pressure, angle, it is ejected into by the method on spray plane. Dry shotcreting method construction technology process is simple, convenient, but dry shotcreting method working face dust and springback capacity are all relatively big, and poor working environment, has pulse phenomenon during material spray, material spray uniformity coefficient is poor.
Dampen shotcreting method relies on pressurized air or transferpump mixing with accelerating chemicals to nozzle by the concrete conveyance of design proportioning in advance, and then high-velocity jet is to by mouth face. Both differences are concrete kinestate differences in the duct, and when being power by means of pressurized air, concrete is transported to nozzle at a high speed in the duct in the way of " thin stream swims " advances; When taking concrete pump as power, concrete is transported to nozzle with " dense stream " mode low speed in the duct, and mixes with pressurized air and accelerating chemicals at nozzle place, and then high velocity spray is to by spray plane. Dampen shotcreting method springback capacity, dust concentration are all lower, but wet spray plant is more complicated and easy to wear, and dampen shotcreting method accelerating chemicals accurately adds comparatively difficulty.
Summary of the invention
In order to overcome the problems referred to above, the utility model proposes a kind of snubber assembly, efficiently solve that above-mentioned dry shotcreting method sprayed concrete is uneven, springback capacity and the high problem of dust content.
Dry shotcrete rotates wet spray priming apparatus, this snubber assembly of this device comprises guide slide 2, buffering sleeve 3, inlet valve, inlet valve comprises the first inlet valve 4, the 2nd inlet valve 5, and the two ends of buffering sleeve 3 are respectively equipped with opening for feed 1, discharge port 6; Guide slide 2 is arranged in buffering sleeve 3; Inlet valve is arranged on the peripheral circumference of buffering sleeve 3.
Guide slide 2 is polyline shaped, guide slide 2 is divided into three-stage structure i.e. the first broken line, the 2nd broken line, tri linear section, wherein, first broken line is connected to the end of buffering sleeve 3 and the circumference of buffering sleeve 3, and tri linear section is connected to the circumference of buffering sleeve 3 and the other end of buffering sleeve 3; 2nd broken line connects the first broken line and tri linear section, and the 2nd broken line is connected to the circumference of buffering sleeve 3; First broken line and tri linear section are arranged symmetrically with.
First inlet valve 4 is arranged on the buffering sleeve 3 circumference place of the first broken line and eighty percent discount line segment intersection; 2nd inlet valve 5 is arranged on the 2nd broken line buffering sleeve 3 circumference place crossing with tri linear section.
Described first broken line and horizontal direction angle are 15 ��-30 ��.
The utility model tool has the following advantages.
Snubber assembly of the present utility model, can change the motion track of sprayed concrete so that it is simple translational motion becomes rotation round motion;
Snubber assembly of the present utility model, can change the direction added water with sprayed concrete jet so that it is has original Vertical dimension to add water and turns into parallel to adding water, is convenient to water and sprayed concrete merges better;
Snubber assembly of the present utility model, adds water from original single level and turns into multistage adding water.
Accompanying drawing explanation
Fig. 1 is the structural representation of snubber assembly of the present utility model.
Fig. 2 is the utility model process flow sheet.
In figure: 1, opening for feed, 2, guide slide, 3, buffering sleeve, the 4, first inlet valve, the 5, the 2nd inlet valve, 6, discharge port.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
The utility model snubber assembly is very easy to use, and a mouth is opened in the dry shotcrete machine nozzle end for routine, and the method adopting screw to connect (pourable resin chock sealing) connects, and water pipe connects two taps.
The key of snubber assembly is to make sprayed concrete spiral inside snubber assembly to advance more than a circle; The diameter of spiral tube can be equally big with spray tube, it is also possible to bigger than spray tube diameter.
Snubber assembly of the present utility model can effectively and sprayed concrete flow to change, sprayed concrete stirring action is strengthened in sprayed concrete spiral motion, cement in sprayed concrete, sand, water three are merged better being ejected into before by spray plane, and springback capacity, dust content can reduce about 30%.
