The length, distance and Bend angle – steel pipe bending – steel pipe laying trench excavation – steel pipe fixing and spot welding – burying – soil slag cleaning – cable laying determine the cable model, laying route, length, start and end according to the drawings and site conditions – cable laying (directly buried through pipes and cable trench laying) Cable head fabrication and secondary wiring stripping cable – cable head fabrication – wire core straightening – wire calibration – Numbering head – cable head bundling – handle bundling – wiring commissioning, arrester discharge test – knife switch circuit resistance test – background manufacturers do background – five prevention factories and five prevention improvement – start remote engine background point-to-point – local opening and closing Realization of remote control opening and closing verification function From the control cabinet B to the mechanism boxes a and C, 8 pieces of opening and closing positions, motor power supply, control power supply, etc., 2 pieces of measurement and control remote signaling and remote control, 2 pieces of motor and control power supply to the circuit breaker terminal box, 2 pieces of three knife mechanism box and ground knife mechanism box to the circuit breaker terminal box, and 1 piece of circuit breaker terminal box to the control cabinet (locking: 2 pieces of three knife mechanism box and ground knife mechanism box to the control cabinet)…
Construction process lightning arrester removal lightning arrester conductor removal – lightning arrester removal – on-line detector removal – discharge counter removal – cement rod foundation crushing – cement rod cutting and demolition crushing ice melting knife gate foundation construction foundation setting out – Foundation Excavation – mold making – reinforcement cage making Welding of embedded bolts – formwork erection – Foundation pouring – Foundation backfilling – transportation of surplus soil, installation of pipe mother, assembly and erection of ice melting cement rod – Welding of rod cap – Welding of pipe mother bracket – Installation of post insulator – Installation of pipe mother splint – Measurement and installation of pipe mother length according to drawings or site conditions – cutting or welding of pipe mother – drilling of pipe mother – Installation of end cap – pipe mother crane Installation – pipe bus adjustment – expansion joint installation and adjustment – ice melting knife switch installation – knife switch equipment rod installation – mechanism box base and mechanism box installation – knife switch base installation – lifting base installation – lightning arrester installation – static contact installation – post insulator – moving contact installation.
Taking the installation of ice melting knife gate as an example, although the project is small, it has all kinds of treasures; Demolition, civil foundation, reinforcement engineering, pipe laying, installation and commissioning (primary and secondary test, background, five prevention, etc.).
