Trolley further includes pumping mechanism VI, can be from 5 delivering concrete wet shot material of trend spray head.
The workflow of above-mentioned mould spray apparatus are as follows: during construction, arm mechanism and electromagnetism template, template before adjusting
Frame etc. is shored, is adsorbed onto electromagnetism template on steel arch-shelf, forms the die cavity of height about one meter (height that template shores frame) left and right,
The angle for adjusting spray head starts to gunite concrete inside die cavity, and during injection, concrete is cumulative, forearm machine
Structure starts to move along steel arch-shelf, while preceding arm mechanism is mobile, drive motor rotation, while discharging the electromagnet mode on reel
Plate, by compressed oil cylinder, top bracing plate|, the devices such as spring-compensating are pressed to electromagnetism template on steel arch-shelf, while electromagnetism template obtains
Electricity is adsorbed on steel arch-shelf, forms new die cavity again.In the way of this movement, continuous moving support frame discharges template,
New die cavity is gradually formed, the continuous gunite concrete of spray head continuously carries out mould and sprays supporting, when reaching vault, stops
Gunite concrete, concrete to be sprayed is all after solidification, and electromagnet is by vault to lower end power loss, while drive motor one by one
It reversely rotates, cantilever crane, which synchronizes, to be moved down, and the recycling to electromagnet template is completed, and is realized without rebound, non-dusting continuous preliminary bracing.
Method is sprayed using the mould of electromagnetism template, described method includes following steps:

Frame and curtain electromagnetism template excavation face wherein side close to the bottom of two adjacent steel arch-shelfs；
S2: electromagnetism template is located to one section before support frame and is close to two or more steel arch-shelfs, and and steel arch-shelf from bottom
Form die cavity to be poured；
S3: adjustment nozzle position and angle opens spray head and Open Side Down at the top of transverse mode control sprays into rapid hardening coagulation
Soil completes pouring for first section concrete；
S4: after section concrete solidification at the beginning of mold cavity bottoms, being affixed on of extending upwards of the modular unit of electromagnetism template is described
On steel arch-shelf, new die cavity is formed, when electromagnetism template extends, spray head is lasting to the modular unit and steel arch-shelf that newly release
Fast hardening concrete is sprayed into the die cavity newly formed, is poured with completing the preliminary bracing of this section unilateral excavation face.
It further include step S5, after top concrete solidification, revolution large arm is gradually moved down with support frame and electromagnetism template,
It drives roller to reversely rotate simultaneously, recycles curtain electromagnetism template；It turns round large arm to rotate horizontally with support frame and electromagnetism template, make
The other side of the electromagnetism template towards tunnel with section time is obtained, and repeats step S1-S4, completes the preliminary bracing of this section of tunnel other side
It pours.
In step S1 and S2, driving roller rotates in the forward direction under the action of drive motor, discharges curtain electromagnetism template, makes
The free end for obtaining electromagnetism template hangs down into its bottom and flushes with the bottom that template shores frame, adjusts the left-right position of support frame, with
Guarantee that the electromagnetism template of curtain can laterally cover the steel arch-shelf；Then the electromagnetism template being located at before support frame that will be released
Outer surface is tightly attached on steel arch-shelf, and guarantees that the bottom edge of electromagnetism template is contacted with tunnel excavation bottom surface, so that electromagnetism template, steel arch
Frame and tunnel bottom surface are enclosed with open-topped transverse mode control；
In step s 2: the power circuit of modular unit electromagnet is successively connected from the bottom up, so that contacting with steel arch-shelf
Modular unit magnetic absorption on steel arch-shelf；The pitch angle for adjusting support frame simultaneously, so that the outer surface of electromagnetism template is most
Limits are agreed with the radian of steel arch-shelf, and adjust revolution large arm template is made to shore frame and withstand electromagnetism template and steel arch-shelf
It is bonded section；
In step s 4, after section concrete solidification at the beginning of mold cavity bottoms, revolution large arm drives support frame gradually along steel arch-shelf
It moves up, while being again started up driving roller and continuously rotating in the forward direction, continuously to discharge the template list of curtain electromagnetism template
Member.
In step s 4, the rate of release with support frame of electromagnetism template move up that speed is equal, and guarantee newly to release
When modular unit and steel arch-shelf contact, institute's band electromagnet is powered immediately to be adsorbed on steel arch-shelf.
During support frame is moved up along steel arch-shelf, template is shored the idler wheel of shoring on frame and is rolled at the back of electromagnetism template
It crosses, while during scrolling, direct support is formed to electromagnetism template.
In the release of electromagnetism template and removal process, the central links in electromagnet mode backboard portion are from upper guide roller and lower steering roll
Annular groove in slip over；The chain of two sides is located at that unit is shored in centre and side is shored and slided between unit.
It is overlapped with the preliminary bracing concrete layer poured at left and right sides of section time tunnel in tunnel top, and in lap-joint
After tamping with template support, strike off, complete the supporting of described section time of tunnel contour.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
