The invention discloses a magnetic levitation long stator coil laying vehicle system. The system comprises: a first vehicle, wherein a cable reel is arranged on the vehicle body of the first vehicle; a second vehicle, wherein cable bending equipment is assembled on the vehicle body of the second vehicle and used for bending and forming the cable conveyed by the cable reel of the first vehicle into a long stator coil; and a third vehicle, wherein external hanging operation platforms for receiving the long stator coils conveyed by the second vehicle are arranged on the two sides of the vehicle body of the third vehicle. The installation efficiency of the long stator coil can be improved, the labor cost is reduced, and deformation is not likely to be caused.

The invention discloses a main pipe construction method for establishing the tunnel formation, comprising following steps: pushing down a leading pipe and an initial main pipe underground; preventing landslide; conveying the next main pipe whose outer diameter is far smaller than the initial pipe to the inside of the main pipe setting space; expanding the diameter of the next main pipe to make it the same as the diameter of the initial main pipe; connecting the next main pipe after expansion treatment with the front end of the initial main pipe; repeating the connection operation of the next main pipe for establishing the tunnel formation. The technique scheme is able to construct in a direct or curve way, swift, safe and simple.

The invention discloses a screw structure assembled auxiliary probe for paving a cable in a high voltage cable trench. The auxiliary probe comprises a probe body. An optical lens is arranged in the head of the probe body. A CCD camera is arranged in the middle of the probe body. The CCD camera is connected to the optical lens. The middle of the probe body is provided with a wireless receiver and ahot spot generator. The wireless receiver and the hot spot generator are connected to an external platform to carry out information exchange. The middle of the probe body is provided with a lithium battery. The tail of the probe body is connected to a probe rod. A spring switch device is arranged in the tail of the probe body. The probe rod contacts with the spring switch device. The external side of the probe rod is fixedly connected to a cable. The external side of the probe rod is provided with a guiding support device. The structural design is reasonable, the practicality is strong, whena cable is paved in a high voltage cable trench, the provided auxiliary probe can smoothly fix the cable to the probe rod, the frequency of opening a cable cover plate is reduced effectively, and thecable pavement becomes more convenient.

The invention discloses a translation traction construction method for a PC narrow and high track beam on a cast-in-place beam, which is characterized by comprising the following steps: S1, translation track installation: paving a leveling cushion block on the cast-in-place beam, and then paving two translation tracks penetrating through the cast-in-place beam on the leveling cushion block; S2, constructing a translation traction mechanism; S3, hoisting and fixing the track beam, specifically, the track beam is hoisted to the position between the two vertical supporting beams on the transverse supporting beam from the side span side face of the cast-in-place beam, and arranging buffering and reinforcing cushion blocks additionally between the vertical supporting beams and the track beam; and S4, performing track beam translation traction. According to the translation traction construction method for the PC narrow and high track beam on the cast-in-place beam, the technical problem that when the PC narrow and high track beam is erected on a cast-in-place pier column in the middle of a bridge and the cast-in-place beam, a crane and a beam transporting vehicle cannot be driven to the bridge to hoist the track beam in consideration of bridge bearing is solved.

The invention relates to a ground tile for laying cables or optical cables. The ground tile is characterized in that through holes are formed in four side directions of the ground tile, and cables or optical cables can pass through the through holes for laying. When the ground tile is used, the required passing angles of cables or optical cables are selected according to the directions of current ground tiles, and the through holes are communicated after the ground tiles are laid and arranged, so that the cables or optical cables cannot be bent after passing through the through holes, and cannot be broken. The through holes are formed in four side directions of the ground tile, and cables or optical cables can pass through the through holes for laying. The required passing angles of cables or optical cables are selected according to the directions of current ground tiles, and the through holes are communicated after the ground tiles are laid and arranged, so that the cables or optical cables cannot be bent after passing through the through holes and cannot be broken, and laying safety of cables or optical cables can be guaranteed.

The invention relates to a floor tile. The floor tile is characterized in that through holes which are used for paving electric cables or optical cables are formed in four sides of the floor tile; during use, the needed through hole angles are selected according to the direction the electric cables or optical cables passing through the current floor tile; after pavement of the floor tiles, the floor tiles are arranged and the through holes are communicated to ensure that the electric cables or optical cables are not bent after passing through the through holes and the electric cables or optical cables are not broken. The through holes which are used for paving the electric cables or optical cables are formed in the four sides of the floor tile, the needed through hole angles are selected according to the direction the electric cables or optical cables passing through the current floor tile, and after the pavement of the floor tiles, the floor tiles are arranged and the through holes are communicated to ensure that the electric cables or optical cables are not bent after passing through the through holes and the electric cables or optical cables are not broken, so that safe pavement of the electric cables or optical cables is ensured.
