Input panel (41) are provided on range controller (42)；The programmable controller (42) by outlet line (43) respectively with electricity
Machine (24) and spray gun are connected.
10. a kind of constructed based on the gunite concrete synovial membrane as claimed in claim 9 for foundation pit side wall construction of leveling blanket is filled
The construction method set, it is characterised in that: the construction method the following steps are included:
1) by rotation roller (14) mobile constructing device as claimed in claim 9 extremely to job position, and pass through rotation roller
(14) the fixed constructing device of self-locking function makes groove steel rail by the posture of telescopic rod (15) adjustment rack platform (1)
(21) in a vertical state；
2) form element (3) decentralization is extremely risen at spray plane by lifting component (2), and passes through telescopic rod (32) adjustment template (34)
Posture, so that template (34) is met design requirement at a distance from by spray plane, while being in plumbness；Pass through the adjustable song of square
Bar (331) adjusts horizontal slide rail (332) position, is adapted horizontal slide rail (332) and template (34)；
3) determining sprayable amount of concrete and unit height are measured by input panel (41) input in advance and wait for pneumatically placed concrete
Spatial volume；
4) spray gun is installed and opens power supply afterwards with the fixture (3332) of spray gun pedestal (333), start motor (24) and injection coagulation
The corollary equipments such as soil preparation and conveying, artificial hand steered spray gun pedestal (333) reciprocatingly slide along horizontal slide rail (332), and realization is sprayed
The uniform charity of face gunite concrete；
5) as gunite concrete gradually applies spray, form element (3) matchingly are stepped up by lifting component (2), until
Operation surface construction to be painted is completed.
