Pile driver for bridge construction suitable for riverway with high water content

Abstract

The invention discloses a pile driver for bridge construction suitable for a riverway with high water content, the structure of which comprises an internal tensioning device, a drill pipe, a connecting block, a fixing frame, and a motor, wherein the internal tensioning device is installed inside the drill pipe; a mechanical connection is adopted between the top of the drill pipe and the inside ofthe connecting block; a lower end of the motor is vertically connected with the interior of the connecting block; and the inner side of the middle end of the fixing frame is welded to the side of theconnecting block. The pile driver for bridge construction suitable for a riverway with high water content can drill holes on the ground when the motor is rotating forward, and when it is necessary toremove the soil from the cave, the motor needs to be reversed first, and the telescopic disk inside the device will be extended to cover the bottom of the hole, and even if the soil is highly mobile,we can take it out quickly, which can improve the work efficiency of the staff, and the telescopic disk can be quickly retracted into the drill pipe inside, increasing the convenience of the device.

Description

technical field [0001] The invention relates to the technical field of bridge construction treatment, in particular to a pile driver suitable for bridge construction with relatively high water content in river courses. Background technique [0002] When building a bridge, we need to use a pile driver to make a hole first and then use cement to pile up the bridge. However, when drilling a hole in a river, the internal soil will be more fluid, and when the drill pipe is taken out of the hole, the soil will flow smoothly. The hole sheet of the drill pipe will flow down, which will increase the useless work done. [0003] At present, the effect of pile drivers is better when drilling holes in dry soil. Once encountering soil with high water content, the soil has strong fluidity, and it is difficult to take out the soil in the hole, and the silt with high water content is easy to settle. Going down, it needs to be applied quickly, otherwise the hole will be filled again. Conte...

[0003] At present, the effect of pile drivers is better when drilling holes in dry soil. Once encountering soil with high water content, the soil has strong fluidity, and it is difficult to take out the soil in the hole, and the silt with high water content is easy to settle. Go down, you need to do it fast, or the hole will be filled again
