Wheeled hydraulic inverting bridge formwork structure
Wheeled hydraulic inverting bridge formwork consists of seven parts: front axle, main bridge, rear axle, front bracket, rear bracket, travel drive and walking bracket.
Wheeled hydraulic inverting bridge formwork The concrete construction under the front approach bridge allows the vehicle to pass through the trestle bridge to the lower step from the filling layer, perfectly matching the concrete construction of the inverting arch (floor) under various step method excavation methods to achieve early closure. Construction requirements for early ring formation.
- The span of the trestle bridge is large, and it can meet the one-time concrete pouring of the inverted arch of 12 meters and 24 meters, which greatly improves the speed of the invert arch construction.
- The strength of the trestle is high, and it can safely pass all kinds of construction vehicles with a weight of not more than 60 tons.
- The space above the trestle is wide, which is convenient for the passage of various construction vehicles. The concrete tanker can conveniently pour the concrete on both sides of the trestle. The excavator can also swing on the trestle without any obstacles, which is convenient for cleaning the residual slag.
- All the components of the trestle are hydraulically driven, which work smoothly and have high reliability.
Wheeled hydraulic inverting bridge formwork instructions for use
Wheeled Hydraulic inverting bridge formwork When the trestle is translated, the stroller walking bracket is folded, the front and rear brackets of the trestle are supported on the ground, the walking bracket is lowered, the front bracket is separated from the ground, and the translation cylinder in the front and rear brackets is controlled to make the trest bridge overall. Panning left and right, placing the front and rear trestles on the ground, the transport vehicle can pass on the trestle, and the construction of the inverting arch is carried out under the trestle. Due to the large span of the main bridge, the excavation of the invert arch and the backfilling of the invert arch can be carried out at the same time, and the slag is discharged. When the trestle is advancing, the walking bracket and the rear travel drive are lowered, the front and rear end brackets are disengaged from the ground, and the travel drive motor is actuated to move the trestle overall forward to a predetermined position. The travel drive device uses rubber tires to walk without laying rails. It can be used for various excavation methods and different working conditions, and can be freely converted at any time. The operation is simple and flexible, and the use surface is extremely wide.
