Efficient pile driver tower and pile driving method

Abstract

The invention relates to an efficient pile driver tower and a pile driving method. The efficient pile driver tower comprises two front-and-back moving guide rails. A front-and-back moving beam is arranged on the front-and-back moving guide rails. The distance between the front-and-back moving guide rails and the front-and-back moving beam in the vertical direction is kept consistent all the time. The front-and-back moving beam is provided with a left-and-right moving beam, and the distance between the left-and-right moving beam and the front-and-back moving beam in the vertical direction is kept consistent all the time. Two or more vertical tower frames are arranged on the left-and-right moving beam in a linear manner. The linear arrangement direction of the vertical tower frames is consistent with or perpendicular to the moving direction of the front-and-back moving beam. Left-and-right moving beam supporting jacks capable of enabling the left-and-right moving beam to stably rise and fall vertically are arranged below the left-and-right moving beam. The weight of the tower is greatly reduced, and the equipment manufacturing and transporting cost is also greatly reduced. A plurality of piles can be driven each moving, and efficiency is very high.

Description

technical field [0001] The invention relates to construction engineering equipment and methods, in particular to a high-efficiency piling frame and a piling method. Background technique [0002] There are many methods for treating large-area soft soil foundations, all of which adopt various pile foundations. The arrangement of each pile is a regular square or equilateral triangle, and the distance between the piles is fixed. [0003] The piling frames of the prior art all have one device and one tower, and only one pile can be driven at a time when moving, so the efficiency is very low. In terms of the structure of the equipment, the vertical towers are all installed on one side of the pile driver chassis to form a cantilever structure. For example: there are two towers on the chassis of some piling frames. In order to meet the safety and stability of the equipment, the equipment is often made very heavy, which makes it very inconvenient to move the piling frame. [0004]...

AI Technical Summary

Problems solved by technology

In the prior art, after the construction of a row of piles is completed, the racks of the two towers in the prior art need to be constructed in the opposite direction when changing a row of piles. The two devices suspended on the two towers need to be replaced. Such a huge It is very difficult to perform transposition on the frame, or perform a U-turn on the spot to realize the front-to-back transposition of the two towers. It takes a long time to turn around on the site, so the construction efficiency is greatly reduced
