Description
Technical field
The present invention relates to underground pipe gallery technical fields, more particularly, to one kind for pouring miniature underground pipe gallery
Split bolt.
Background technique
Underground pipe gallery is construction in Urban Underground, for concentrating laying electric power, communication, radio and television, water supply, draining
The public tunnel of equal municipal pipelines.Underground pipe gallery can effectively prevent " zipper road " phenomenon, allow technical staff without repeatedly
Excavated pavement can repair all kinds of pipelines in piping lane, be safeguarded, extending capacity reformation etc.；Reduction pipeline repairing significantly simultaneously
Time.
Currently, mostly using cut and cover method to apply for miniature underground pipe gallery (a height of 1.8m × 1.8m of cross section width or so)
Work.
Currently, the inner template and exterior sheathing of the vertical side wall for pouring underground pipe gallery usually pass through several to drawing
Bolt carries out assembling splicing and fixes, and for above-mentioned inner template and exterior sheathing, engineering staff prefers to compare using length and width
Big big plate so advantageously reduces the assembled workload of template, advantageously ensures that coagulation as inner template and exterior sheathing
The flatness etc. in cob wall face.But a problem is also brought using all bigger inner template of length and width and exterior sheathing: connection
The split bolt of inner template and exterior sheathing needs are manually installed, usually first external mold board placing to predetermined position, then will
The outer end of split bolt passes through steel reinforcement cage from inside to outside and is fixed on exterior sheathing, and inner template is then mounted on split bolt again
It on inner end, so installs, exterior sheathing is first installed, inner template is installed again, it is more time-consuming, furthermore how many split bolt, it is interior
With regard to how many a eyelet for across split bolt in template, so more split bolt is all mounted on exterior sheathing one step ahead
Afterwards, being aligned numerous eyelets in inner template with numerous split bolts one by one behind allows split bolt insertion to come in, show and
Easy insight, so many alignment one by one are more time-consuming.
Therefore, more time saving when how a kind of installation inner template and exterior sheathing are provided, save trouble, labour-saving split bolt is
The technical issues of those skilled in the art's urgent need to resolve.
