Piling device for urban road traffic engineering construction

Abstract

The invention discloses a piling device for urban road traffic engineering construction, and relates to the technical field of road engineering construction. The piling device for urban road traffic engineering construction comprises a stand column, a drill rod and a spiral blade which are arranged on a machine body, the side wall of the stand column is fixedly connected with a fixing plate, the side wall of the fixing plate is fixedly connected with a supporting plate, and the side wall of the supporting plate is fixedly connected with a plurality of first connecting plates arranged in an array mode. According to the pile driving device, when the drill rod is lifted, air flow can generate thrust on soil on the spiral blades, the soil is prevented from falling off in the lifting process of the drill rod, meanwhile, when the soil on the drill rod is unloaded, air blowing cleaning can be conducted on the soil on the surfaces of the spiral blades, the pile driving efficiency and effect are guaranteed, and in addition, the soil is conveniently collected, so that the pile driving efficiency is improved. After the drilling rod is lifted, soil can be unloaded, the drilling rod does not need to be moved away, the piling efficiency and effect are guaranteed, and meanwhile the protection holes and the holes are prevented from being damaged.

Description

technical field [0001] The invention relates to the technical field of road engineering construction, in particular to a piling device for urban road traffic engineering construction. Background technique [0002] The existing urban road traffic engineering construction usually uses a screw pile driver when piling. When the screw pile driver is piling, it is necessary to drill the auger rod into the soil, and then lift the drill rod from the hole to be lifted. Turn the drill pipe to one side after it is in place, and then reverse the drill pipe to remove the soil on the drill pipe. [0003] However, when the existing screw pile driver is in use, when the drill pipe is lifted out of the hole, the soil on the drill pipe will fall into the hole, thereby affecting the effect and efficiency of piling. After that, it will remain, which will also affect the effect and efficiency of piling. In addition, every time the soil is removed, the drill pipe needs to be turned to one side. ...

Problems solved by technology

[0003] However, when the existing auger pile driver is in use, when the drill rod rises from the hole, the soil on the drill rod will fall into the hole, thereby affecting the effect and efficiency of piling. At the same time, the soil on the drill rod is being unloaded There will be residues in the end, which will also affect the effect and efficiency of piling. Moreover, each time the soil is unloaded, the drill pipe needs to be turned to one side. After the unloading is completed, the drill pipe should be inserted into the hole. method, it is easy to cause damage to the protective hole in the hole, and then cause damage to the hole, affecting the effect and efficiency of piling
