TUNNEL FORMWORK

The automatic hydraulic tunnel formwork is the equipment to make
the concrete lining for the tunnel in one time.The empty gantry allows the
transport vehicles to pass. The motor gearbox is adopted to drive
the whole equipment, the formwork is fully hydraulic, with hydraulic
cylinder to prop & strip, and lock mechanically

◆  Good concreting quality

◆  High-speed of installation and removal of the form

◆  Easy operation and safety

Q:What is the simple calculation method of the tunnel excavation unit price
Comprehensive unit price methodAs the calculation method of this method and the project of comprehensive unit price, is calculated according to the real need of engineering cost measures the amount of consumption and real price, applicable to the calculation of the amount of engineering projects, mainly refers to the number of entities are closely linked and engineering projects, such as concrete formwork, scaffolding, vertical transportation etc.. Different from the sub project, it is not required that the comprehensive unit price of each measure must include the labor cost, material cost, mechanical cost, management fee and profit.
