Description
Technical field
The present invention relates to moulds to spray field, refers in particular to a kind of mould material spray agent spraying system.
Background technique
In tunnelling work progress, it is necessary to, could be in tunnel after first carrying out support reinforcement to the palisades that excavation is opened
Constructed or excavated latter section of tunnel；Otherwise tunnel palisades can be because lead to tunnel situations such as loosening, soil erosion, weathering
It collapses.
Existing tunnel palisades generally will do it two numbers support；It is once to make concrete first by concrete spray on palisades
Rapid condensation forms just branch layer, to tunnel rapid reinforcement；Second of supporting is the gunning concrete on established just branch layer；It is right
Tunnel palisades are reinforced again, form secondary supporting layer；Wherein secondary supporting layer is main stress layer.
In the construction of first branch layer, existing arrangement and method for construction is directly by concrete spray on tunnel palisades surface；And at this
A large amount of material can be made to rebound on palisades in spraying process, cause the waste of material, and will cause can be in the presence of a large amount of in tunnel
Dust pollution, while being constructed just branch layer using existing mode, just branch layer surface extremely out-of-flatness can be made, be not easy to secondary branch
The spraying of sheath will affect the load of secondary supporting layer.Even sometimes in order to which the setting of secondary supporting layer is also by first branch layer
The place of out-of-flatness knocks out, troublesome in poeration, and can damage to first branch layer.
Summary of the invention
It is an object of the invention to: a kind of mould material spray agent spraying system is provided, which passes through material agent
Mixer sprays into concrete and accelerator in die cavity after quick, abundant, uniform mixing, make concrete fast rapid hardening in die cavity
Gu guaranteeing the quick setting of just branch layer, guarantee construction safety.
The technical solution adopted by the invention is as follows:
A kind of mould material spray agent spraying system, including concrete pumping mechanism, accelerator pumping mechanism, compressed air supply arrangement and
Expect agent mixer；It is characterized by: the concrete pumping mechanism binder agent mixer, send concrete into material agent and mixes
Device；Accelerator is sent into material agent mixer and is mixed with concrete by the accelerator pumping mechanism binder agent mixer;It is described
Compressed air is sent into material agent mixer by compressed air supply arrangement binder agent mixer;It is set on the material agent mixer
There is spray head.
Mould spray is that template is being arranged on tunnel palisades, makes to form die cavity between template and tunnel palisades；Then make spray head
It is placed in the entrance of die cavity, concrete is sprayed into quickly in die cavity and fills up die cavity；And in the prior art, without a kind of equipment
Concrete and accelerator can be made to spray into die cavity quickly, sufficiently, after evenly mixing.The present invention provides a kind of mould material spray agent sprays
Penetrate system, in the mould material spray agent spraying system due to expect agent mixer presence, concrete pumping mechanism send out concrete and
The accelerator that accelerator pumping mechanism is sent out being capable of quick, abundant, the uniform mixing in material agent mixer；Compressed air simultaneously
Supply arrangement, which can be fed in agent mixer, provides compressed air, provides pressure for mixed concrete, it is made quickly to be sprayed onto mould
Intracavitary, the concrete after enabling spray head to spray quickly condenses, and then makes quickly be formed just branch layer on palisades, quickly
Tunnel palisades are reinforced.Simultaneously because compressed air enters in material agent mixer, it can more quickly, sufficiently, uniformly
Make accelerator and concrete material agent mixer in mix.
Further, template is arranged in the spray head and tunnel palisades are formed by the entrance of die cavity, will be mixed with rapid hardening
The concrete ejection of agent enters in die cavity.
Since spray head is placed in the entrance of die cavity, concrete is all sprayed into die cavity, avoids the rebound of concrete, is saved
Material, avoids in tunnel that there are a large amount of dust；Meanwhile first branch layer be by cavity forming, therefore after form removable,
The surface of first branch layer keeps the thickness distribution of secondary supporting layer more uniform, favorably for burnishing surface convenient for the construction of secondary supporting layer
In the load of secondary supporting layer；It knocks out at the out-of-flatness of first branch layer, is avoided to first when avoiding setting secondary supporting layer simultaneously
Branch layer damages, and influences just branch layer stress.
Further, the material agent mixer is hollow structure, and the outlet end of the material agent mixer connects spray head, described
Expect that the input end of agent mixer connects concrete pumping mechanism；The side wall of the material agent mixer is filled equipped with several accelerators
Mouthful, the accelerator filler connects accelerator pumping mechanism, mixes accelerator in material agent mixer with concrete；It is described
Expect also to be provided with gas filler on the input end or side wall of agent mixer, the gas filler connection compressed air supply
Equipment.
Due to above structure, expects to be provided with multiple accelerator fillers on agent mixer, concrete and accelerator can be made
It is more fully mixed in material agent mixer, guarantees the concrete rapid condensation after spray head sprays, form just branch layer.
Further, the accelerator pumping mechanism connects flow mixing device, and accelerator is sent into flow mixing device；The compression is empty
Gas supply arrangement connects flow mixing device, and compressed air is sent into flow mixing device and is mixed with accelerator;The flow mixing device binder agent is mixed
The accelerator for being mixed with compressed air is sent into material agent mixer and is mixed with concrete by clutch.
In said structure, accelerator is first uniformly mixed and is reinjected in material agent mixer with compressed air, can be made in this way
The certain pressure of accelerator band, can more fully mix with concrete, and also provide power for the ejection of concrete.
Further, the material agent mixer is hollow structure, and the outlet end of the material agent mixer connects spray head, described
