Abstract

The invention provides a drilling device, comprising a base, a machine body, a drill bit lifting device, a connecting rod drilling machine, at least two drill bits and a guide rail, wherein the drill bits can be controlled independently; the drilling device can drill a plurality of holes in one step, so that the drilling efficiency can be improved exponentially, and repeated work is prevented. Meanwhile, the invention further provides a method for cutting a reinforced concrete supporting beam. According to the drilling device and the method for cutting the reinforced concrete supporting beam, the drilling device is arranged on the surface of the reinforced concrete supporting beam, so that a plurality of holes can be drilled at intervals in one step, and the working efficiency for drilling and cutting the reinforced concrete supporting beam is greatly improved.

Description

technical field [0001] The invention belongs to the field of underground geotechnical engineering construction, in particular to a drilling device and a cutting method for a reinforced concrete support beam. Background technique [0002] At present, urban housing construction is in a stage of rapid development, high-rise and super high-rise buildings are constantly emerging, and the number of deep foundation pits is also showing a trend of rapid development, and it is often necessary to excavate deep foundation pits in complex terrain environments . In order to protect the safety of the surrounding buildings (structures) and the structure of the deep foundation pit itself, the deep foundation pit must be effectively supported during the construction process. It is often necessary to add an internal support system in the deep foundation pit. The reinforced concrete support beam can Many advantages such as effective control of foundation pit deformation are widely used in dee...
