The self-propelled hydraulic inverting bridge formwork adopts mechatronics and hydraulic integration design, equipped with multi-functional automatic walking device, front support, rear lateral movement mechanism, hydraulic self-balancing system, which can realize automatic vertical movement, rise and fall, and automatic horizontal movement, with a high degree of automation , Can adapt to a variety of construction work […]

Introduction As the development of road traffic brings rapid economic development, the construction of roads and tunnels is becoming more and more common. Under normal circumstances, during the tunnel lining construction, concrete often has problems and defects such as leaking bars, pitting and cracks. Although it has no direct impact on the actual use of […]

Hydraulic inverting bridge formwork is one of the main components of the tunnel structure, it is the foundation of the tunnel structure. On the one hand, it is necessary to effectively transmit the formation pressure of the upper part of the tunnel to the underground through the tunnel side wall structure or the load on […]

The secondary lining is carried out after the surrounding rock and the initial support deformation are basically stabilized according to the measurement situation, and it closely follows the excavation surface to meet the safety distance requirements for excavation and lining. The secondary lining uses a 12m formwork trolley, and the concrete is transported to the […]

With the rapid development of transportation, tunnels, as important buildings on highway lines, have undergone tremendous changes in terms of tunnel length and construction technology. Tunnel lining is a permanent support structure built with reinforced concrete and other materials along the periphery of the tunnel body to prevent deformation or collapse of the surrounding rock. […]
