Cylinder pilot shaft excavation construction platform.Cubic metre of earth and stone open cut uses the construction principle of " draining is advanced, controls explosion, and supporting is followed up in due course ",
Side slope uses shotcrete support, it is ensured that stability of slope.Construction drainage, control explosion, side are properly carried out in implementation process
Work such as slope supporting, and be considered as Pluvial influence, take the anti-collapse measure of flood control to Pluvial construction, it is ensured that engineering construction safety and apply
Working medium amount.1 elevation 763.70m~714.95m of pit shaft is excavated, and by the way of well digging, excavates one temporarily from tailrace tunnel fork
Access tunnel is to workshop excavation area as 1 bottom tap cinder construction channel of pit shaft.
1 excavation supporting implementation method of pit shaft with steps are as follows:
1 pilot shaft excavates: using the pilot shaft of drilling and blasting method digging diameter φ=2m, pilot shaft is excavated using stage excavation from top to bottom, is excavated
Drilling depth controls within 2m, and using YT-28 hand air drill pore-creating, well head sets up hoisting frame, 2T electric hoist using channel steel or I-steel
Slag is hung, personnel, material are transported by travelling bogie.
2 slag tap well excavation: well of slagging tap excavation digged using pilot shaft, using the quick-fried method of light dig to φ=4m diameter go out
Slag well.It digs use " positive well method " and is layered from top to bottom and excavated, drilling depth control is excavated within 2.5m, using YT-28 hand
Air drill pore-creating slips slag using pilot shaft, is slagged tap using side turn over loading machine cooperation 10t dumper to specified cinder field in shaft bottom.Every row
It slags tap in time after big gun, prevents wellbore bottom accumulated slag from excessively causing blocking in well.
3 area pit shaft Zhu Wa excavation supportings: it is quick-fried that the area pit shaft Zhu Wa uses crawler belt hidden hole drilling and hand air drill to be layered brill from top to bottom
To design sideline, II, III class surrounding rock excavates drilling depth control within 3m, and IV, V class surrounding rock excavates drilling depth control within 2m.It adopts
With loading machine or bull-dozer collection slag, slag is sent, slag charge is excavated and is slipped by well of slagging tap to access tunnel, side turn over loading machine fills 10t certainly
Automobile is unloaded to slag tap.
Carry out borehole wall supporting after the completion of 4 every layer of excavation in time: long anchor pole uses hidden hole drilling pore-creating, and Short bolt is using hand air drill
Pore-creating, manually installed anchor pole, anchor rock mud filling machine slip casting；Pneumatically placed concrete applies spray using TK650 wet-spraying machine fragment, layering.To workshop
The poor side wall of left and right sides geological conditions is segmented the supporting of pouring reinforcement concrete concealed beam.
Excavation between 5 elevation 714.95m~711.20m: by the way of slot digging.Main body rock excavation is latent using crawler belt
Hole drill and hand air drill bore quick-fried, short-delay blasting, and design specification line uses the pore-creating of hand air drill, and presplit blasting or photoface exploision, corner are adopted
It is quick-fried with hand air drill brill, it excavates rock ballast and is slagged tap using 1m3 excavator dress 10t dump truck, excavation of foundation pit sets pumping for water pump cooperation.
The present invention enriches the selection of workshop arrangement form, and Shaft Excavation is excavated by pilot shaft, well of slagging tap excavates and well
Cylinder digs to be formed, and pit shaft buried depth is deeper, can effectively reduce the problem on deformation of factory building foundation, and preferable adaptation to the ground is saved engineering and thrown
Money shortens the completion time of project, generates preferable economic results in society.
Finally, it is stated that preferred embodiment above is only used to illustrate the technical scheme of the present invention and not to limit it, although logical
It crosses above preferred embodiment the present invention is described in detail, however, those skilled in the art should understand that, can be
Various changes are made to it in form and in details, without departing from claims of the present invention limited range.
