Embodiment 14
A kind of mould spray method of tunnel support layer, described method includes following steps:
S1: it by large arm mechanism controls template mechanism and nozzle component jointly close to tunnel target palisades, is bowed by template
Angle of the oil cylinder adjusting template ontology relative to palisades is faced upward, so that stencil body, scar and other subsidiary body/accessory structures are matched
Close the die cavity formed for pouring；
S2: on template mechanism, by spray head displacement mechanism adjust nozzle component relative to die cavity front-rear position and
Lateral position, so that nozzle component is located at the surface of die cavity；Then the opposite of nozzle component is adjusted by spray head micro-adjusting mechanism
In the pitch angle and lateral angles of die cavity, nozzle component is enabled to pour mouth towards at the top of die cavity with optimal angle；
S3: opening spraying system, and to nozzle component delivering concrete, the nozzle of nozzle component sprays into coagulation into die cavity
Soil, until die cavity pours completion；
S4: when die cavity inner concrete reaches solidification, template mechanism is disengaged and is moved up along tunnel palisades, according to step
The method of rapid S1 forms new die cavity, and the solidification concrete of template bottom and neighbouring lower part overlaps, by the solidification coagulation
Soil closes the bottom of new die cavity；Step S2 and S3 are repeated, and completes pouring for new die cavity.
S5: repeating step S4, is poured with completing the branch sheath mould spray of this section unilateral palisades from bottom to top；
S6: turning to tunnel with the other side of section time for template mechanism and nozzle component simultaneously, and repeat step S1-S5, complete
The mould spray of cost section time other side palisades pours.
It further include step S7, the supporting concrete layer for allowing tunnel to pour with section time left and right sides wall is taken in tunnel top
Connect, and after lap-joint tamps with template support, strike off, the mould spray for being performed integrally this section time of tunnel contour pours.
After the mould spray for completing section time palisades pours, step SI-S7 is repeated, continuously to carry out mould to tunnel depth
Spray pours.
What is be spaced on the palisades is provided with steel arch-shelf, and the template is affixed on two or more adjacent steel arch-shelfs, so that
Die cavity to be poured is formed between template, palisades, steel arch-shelf and tunnel bottom surface or adjacent lower part solidification concrete.
In the palisades bottom first floor die cavity forming process of tunnel each section time, so that template bottom is contacted with tunnel bottom surface,
It is closed so that tunnel bottom surface forms first floor mold cavity bottoms.
According to target palisades at a distance from large arm turntable, pass through the flexible and large arm turntable of revolution large arm rotation group vertically
The rotation of part controls, and just successive step is carried out to template mechanism and nozzle component, to approach target palisades.
When there is lateral angle between template and palisades, before being controlled by rotating mechanism arm mechanism with template at a slow speed
Rotation, until template and target palisades keeping parallelism, to compensate the angle between template and palisades.
After the unilateral palisades mould of the same section time, which sprays, to be completed, by the effect of the horizontal rotation component of large arm turntable,
It drives revolution large arm and nozzle component and template mechanism to rotate to other side progress mould spray to pour.
After the whole mould spray for completing section time palisades pours, by the sliding of the mobile seat mechanism of slipping mechanism with
Big arm mechanism and template mechanism on big arm mechanism and nozzle component are generally longitudinally moved into tunnel, so that big arm mechanism exists
The mould spray that the position of tunnel longitudinal direction is adapted to next palisades section time pours.
When mobile seat mechanism is slid onto the end of rail mechanism, and the rotation compensation of combination large arm turntable, revolution large arm is stretched
Truncate is repaid and the accumulation of the rotation compensation of rotating mechanism can not make template form the die cavity that can be poured with next section palisades
When, mobile seat mechanism can be backed to the initial position of rail mechanism, and trolley is moved forward once.
As template mechanism up moves, the angle between template and preceding arm mechanism constantly reduces, and leads to template mechanism
Top increases at a distance from nozzle component, can adjust spray head longitudinal direction slide accordingly relative to preceding arm mechanism forward slip, so as to
Nozzle component and the distance between the die cavity newly formed are maintained in a suitable range.
Nozzle component is continuously into die cavity course of injection, and shower nozzle fixes seat on traversing arm continuously laterally move by left and right
It is dynamic, so that the nozzle component in shower nozzle fixes seat continuously moves left and right at the top of die cavity.
Nozzle component, when nozzle component is moved close to the two sides of die cavity, is sprayed into the continuous course of injection of die cavity
Head micro-adjusting mechanism control nozzle component low-angle rotates left and right, to guarantee the concreting of die cavity junction on the inside of steel arch-shelf
Quality avoids hollowing occur in junction.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within mind and principle.
