The specific embodiment
Describe the specific embodiment of the present invention in detail below in conjunction with accompanying drawing.It should be noted that hereinafter only the present invention's feature unlike the prior art to be described,, just do not given unnecessary details here for the technical characterictic that can find in the prior art.
At first referring to figs. 1 through Fig. 3, concrete wet spraying equipment is according to the preferred embodiment of the invention carried out on the whole introduction.This concrete wet spraying equipment mainly comprises: pumping mechanism 2, accelerating admixture feed system 4, shower nozzle 8, transmission and concrete transmission pipe assembly 3 and removable support wherein, have constituted wet shot mechanism 1 jointly by accelerating admixture feed system 4, shower nozzle 8 and removable support.Pumping mechanism 2 is used for concrete pumping, accelerating admixture feed system 4 is used for the supply of accelerating admixture, after the accelerating admixture that shower nozzle 8 is supplied with the concrete of pumping mechanism 2 pumpings and accelerating admixture feed system 4 mixes, and be ejected into by compressed air differentiation and be subjected on the spray plane, and transmission and concrete transmission pipe assembly 3 one ends removably are connected to the discharging opening of pumping mechanism 2, the other end removably is connected on the shower nozzle 8, carries to realize concrete long distance.
Particularly, with reference to Fig. 2 and shown in Figure 3, accelerating admixture feed system 4 is via coagulant sebific duct 5 and one way valve 6 and be connected to accelerating admixture input port on the shower nozzle 8, and the compressed air tunnel (not shown) can be connected to the compressed air input port 7 on the shower nozzle 8, so that shower nozzle 8 with concrete under compressed-air actuated effect, add quick coagulator for injecting to being subjected on the spray plane.External compressed-air actuated access can be realized in compressed air input port 7.Compressed air pressure is generally at 0.5～0.7mpa, and realization will be carried the concrete weathering of coming by pumping mechanism 2, and with the concrete of original integrality, weathering is vaporific, realizes that vaporific concrete is being subjected to the curing of spray plane.
Particularly, support comprises the upper bracket 11 of the bottom A-frame 9 that is supported in ground, the described shower nozzle 7 of carrying, and A-frame 9 and upper bracket 11 removably link together by pressing plate 10 and bolt, shown in the part of the I among Fig. 2.Therefore, can above-mentioned upper bracket 11 for convenience detach and A-frame 9.Shown in the II part of Fig. 2, upper bracket 11 is that screw is connected with the connected mode of shower nozzle 8, also is easy to dismounting.
With reference to Fig. 4, for showing the transmission and concrete transmission pipe assembly 3 in the concrete wet spraying equipment and the schematic diagram of the connected mode between the concrete sebific duct 12.As can be seen from the figure, reducing steel pipe 14 has been realized being connected of transmission and concrete transmission pipe assembly 3 and concrete sebific duct 12, by pipe clamp 15,13 reducing steel pipe 14 1 ends is connected to transmission and concrete transmission pipe assembly 3, and the other end is connected to concrete sebific duct 12.
With reference to Fig. 5 and Fig. 6, accelerating admixture feed system 4 is introduced.This accelerating admixture feed system mainly comprises accelerating admixture case 41, wherein deposits accelerating admixture; Hydraulic power unit 42, the pumping accelerating admixture; Measuring pump 44, the flow of control accelerating admixture; And underframe 43.The accelerating admixture feed system links to each other with one way valve 6 via accelerating admixture sebific duct 5, can realize accelerating admixture is transported to shower nozzle 8 from accelerating admixture system 4.The function of accelerating admixture system is the accelerating admixture of realizing leaving in the accelerating admixture case, is transported to shower nozzle controllably, quantitatively, mixes with compressed air.Accelerating admixture can make the concrete setting time of sending forth shorten, and reduces concrete resilience, saves cost.Be to be noted that accelerating admixture case 41, hydraulic power unit 42 and measuring pump 44 all removably are supported on the underframe 43 by screw, nut etc. (referring to shown in the I among the figure part), so that the dismounting during carrying.
According to less, each part detachable of wet shot mechanism's 1 volume of the present invention.Particularly, accelerating admixture system 4, accelerating admixture sebific duct 5, shower nozzle 8, upper bracket 11, A-frame 9, concrete sebific duct 12 etc. are all detachable, and convenient transportation relies on and manually just can transport, and the construction space that needs is little.This wet shot mechanism 1 convenient moving, particularly in the down-hole, many tunnels can only hold a people to be passed through, and bigger so a little equipment just can not pass through, and the wet shot mechanism that under a kind of like this space, volume is little, each parts can be dismantled seems particularly important.Pumping mechanism just can be installed in different tunnels with wet shot mechanism, can realize the wet spraying process of long distance, down-hole complicated construction space environment.For example, pumping mechanism 2 can be placed on a bigger tunnel, and by the layout of transmission and concrete transmission pipe assembly 3, wet shot mechanism 1 just can be placed in less tunnel, other space, has overcome the restriction of subsurface environment complexity.
Adopt the split type concrete wet spraying equipment of technique scheme, can realize two kinds of functions.A kind of function is, removes wet shot mechanism 1, and promptly pumping mechanism 2 is realized the long distance pumping in concrete down-hole with transmission and concrete transmission pipe assembly 3, realizes dragging pump or dashes the function of filling out pump.Another kind of function is, can be used for the wet shot in the long distance in down-hole, very little space, and conveniently moving is flexible, and pumping mechanism can be split-type structural in different tunnels with injection equipment, and fed distance can reach about 350 meters.
The above is the preferred embodiments of the present invention only, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.All any modifications of being done within the spirit and principles in the present invention, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
