construction of the cross-sea bridge

Gas lift reverse circulation drilling rig is a kind of special Drilling Equipment for bridge construction and piling foundation construction. It adopts gas lift technology and reverse circulation drilling technology, and can be used in the construction of cross-telephone bridge.

First, the air lift reverse circulation drill requires lifting equipment to be installed on the piers in the bridge to lift the drill to the construction location. The rig then levitates itself above the bridge using gas lift technology to reduce the impact on the bridge.

Next, the rig was constructed using reverse circulation drilling technology. Reverse circulation drilling is a drilling technique in which the drill pipe and drill bit are sent through the drill into the formation below the bridge and the cuttings are brought out of the hole through a mud circulation system. This drilling method can effectively control the problems of mud gushing and soil collapse during drilling.

During the construction process, the drilling rig can drill, coring, grouting and other operations as needed to ensure the stability and safety of the bridge. At the same time, the drilling rig can also adapt to the requirements of different strata and bridge structures by adjusting drilling parameters and construction technology.

In general, the gas lift reverse circulation drill in the construction of the bridge has the following advantages: less influence on the bridge in the construction process, high construction efficiency, and controllable construction quality. This makes it one of the commonly used equipment in bridge construction.
