| Abstract:This paper mainly introduces ZT-TG500 type pipe pushing machine about its parameters, working principles, main structure and functions, key technology and the usage. This machine plays an auxiliary role for trenchless equipments in the trenchless construction process, can save the stuck section in pipeline construction and also can help trenchless equipment push the pipeline forward, so as to ensure the success of the project. Due to the use of electro-hydraulic proportional control technology, zero to maximum stepless speed regulation can be achieved, which has brought a lot of benefits to the construction. Vulcanized rubber vulcanization coating technology is used, by the key data in the test, to meet the parameter requirement in practical engineering; with double oil cylinder synchronous anti-torsion technology, using mechanical hydraulic control methods of sliding rail and large shunt valve to realize zero resistance of the cylinder, which can effectively provide the cylinder thrust for the project. This pipe pushing machine is applied in Qingzhou water pipe laying and water piper laying crossing Songhuajiang with good effect. |
