■Introduction

 Description:

LZ-9E/S Shotcrete system for tunnel boring machine is a multifunctional rotor type machine for wet and dry spraying and conveying, with Max. Output 9.5m³/h. The materials that can be transported and sprayed with this kind of machine are mainly as follows: concrete, gunite, mortar, refractory, masses, sand, fine gravel, and crushed stone.

LZ-9E/S shotcrete machine for TBM compared with the traditional spraying and conveying machine, it has several advantages: hydraulic floating compression (pressure automatic compensation after the rubber sealing plate is worn), hydraulic lifting rotor body, automatic anti-blocking function, automatic lubrication, the local control mode and remote control function with PLC control system, which greatly enhance the degree of automation of the machine and increase the machine efficiency. Therefore, this machine is installed into the TBM for the pea gravel spraying, as well as it is widely used in tunnels’ projects, slopes’ consolidations, channels’ restorations etc.

 Application:

LZ-9E/S automation shotcrete machine for TBM is widely adopted for the pneumatic conveyance of pea-gravel when tunnelling with a TBM. The shotcrete machine machine’s flexibility both in terms of workable mixes and outputs ranges, allows a very wide field of applications. Therefore, this automation shotcrete machine for TBM is installed into the TBM for the pea gravel spraying, as well as it is widely used in mines, tunnels, culverts, subways, hydropower projects, underground projects, etc.

■Technical Parameters

Specification (with Electric motor drive):

1. Automatically clean delivery line blockage: PLC+VFD+Air Pressure Sensor.
2. Sector hole to replace the circle hole in the rotor to improve the volume of the rotor and to decrease friction area, then with the same output, the rotor speed will be lower to improve the work life of the rubber sealing plate and keep the motor power lower.
3. Hydraulic floating compression (pressure automatic compensation after the rubber sealing plate is worn).
4. To add an automatic lubricator to the rubber seal plate to make the work life of worn parts longer and make the motor power lower.
5. Intelligent anti-clogging pipe system.
