Description
Technical field
The present invention relates to convey electric equipment basal perimeter terrace anti-freeze expansion field, relate more specifically to a kind of indoor power and set
The method of standby basal perimeter terrace anti-freeze expansion.
Background technology
The indoor equipment basal perimeter terrace that extremely frigid zones install conveying electric equipment can generally occur frost heave in the winter time, cause transmission of electricity
Equipment device damage, it is impossible to normal conveying electricity, maintenance needs large-area power-cuts, once the production and living having a power failure the masses are influenceed,
Maintenance cost is very high, and the influence caused to society is very big.
The content of the invention
For above-mentioned technical problem the invention provides a kind of method of indoor power Equipment Foundations anti-freeze expansion, it is by equipment
Basis pours → and building block filling → flooring pours the completion of three steps；It is the position for installing equipment indoors that the Equipment Foundations are poured
Digging foundation ditch is put, foundation depth ensures to be deeper than frozen soil layer thickness or is connected with equipment room floor, the size and shape of foundation ditch is according to setting
It is standby it needs to be determined that, then use concrete placing installation basis（1）, Equipment Foundations（1）It is poured into residual thickness 15cm to 20cm
And cannot be less than 6 times of built-in fitting tension rib diameter, Equipment Foundations（1）The top insertion built-in fitting drawknot of the scope of operation is poured first
Muscle（9）, built-in fitting tension rib（9）Overall length is exposed and more than the face of pouring cannot be less than built-in fitting drawknot not less than the 80% of design length
Muscle（9）6 times of diameter, built-in fitting（8）The straight muscle of reinforcement welding tension rib of bottom design requirement, length is straight not less than tension rib
6 times of footpath, in Equipment Foundations（1）Built-in fitting is carried out when pouring building body initial set first（8）Levelling, contraposition, and by built-in fitting tension rib（9）
Upper and lower two parts are welded, and weld bond length is not less than built-in fitting tension rib（9）6 times of bilateral full welds of diameter, the building block is filled out
Fill is by indoor base plate（2）Fill and lead up and tamp at ground -50cm to -70cm in Equipment Foundations periphery backfill；Use aerating
Block（3）Equipment Foundations periphery is filled to terrace and is located to -10cm, it is base plate indoors that the flooring pours（2）Packed layer
On use reinforcing bar（4）With tension rib within the walls（5）Connection, reinforcing bar（4）Longitude and latitude is worked out, and spacing is with 10cm to 20cm between reinforcing bar longitude and latitude
It is advisable, reinforcing bar（4）Diameter be advisable with 8~12mm, then by steel bar layer carry out concreting to -1cm to -2cm locate, according to
Design requirement carries out ground finish coat（7）Treatment, in basic built-in fitting（8）Upper fixed power equipment（6）.
The beneficial effects of the present invention are：1st, due to aerated blocks（3）Belong to nonrigid material, with porous frangible spy
Property, the rigid power of soil freezing heave will not be passed to ground, cause indoor power Equipment Foundations with ground because frost heave amplitude is different
Crimp is caused, secondly concreting ground（7）Inside it is provided with reinforcing bar（4）, reinforcing bar（4）With wall lacing wire（5）Fix this just
So that concreting ground（7）As rigid ground, transmission facility is not interfered with, reduce the number of times of large-area power-cuts, saved
About cost, saves artificial.2nd, Equipment Foundations are poured at twice, and intense adjustment, very big width can be carried out to equipment basic pre-buried part
Degree improves equipment basic pre-buried part flatness control, reduces equipment basic pre-buried part out-of-flatness and causes equipment fragility connector
Long-term stress causes to damage, and further protection and power equipment reduce the number of times of large-area power-cuts, cost-effective, save people
Work.
