Row batter pile driving construction method and variable amplitude static pile press for implementing method

Abstract

The invention discloses a raw batter pile driving construction method and a variable amplitude static pile press for implementing the method. The construction method comprises the following steps of placing the pile press in place, placing and debugging the pile press, horizontally calibrating the pile press, calibrating the pile pressing position, calibrating the pile pressing inclination degree,hoisting and feeding a pile, pressing the pile, and constructing a next batter pile to be constructed. According to the construction method, a plurality of batter piles in the same row can be completed by once leveling and moving the pile press, the construction operation of the plurality of batter piles in each row only needs displacement without repeated pile press moving and leveling, construction efficiency is improved, and the cost is saved. According to the variable amplitude static pile press, the transverse moving distance is increased through a long ship, once the pile press is movedand leveled, only displacement of a hydraulic pile press mechanism is needed, the multiple batter piles in the same row can be completed, and the construction speed is improved.

Description

technical field [0001] The invention relates to the technical field of hydraulic pile drivers, in particular to a piling construction method for row inclined piles and a variable-amplitude static pile driver for implementing the method. Background technique [0002] Static pile driver has been paid more and more attention because of its low noise, no vibration, no pollution and high construction efficiency. However, the dimensions of the pile driver relying on its own weight as the counter force increase with the increase of the pile driver's tonnage. And in many occasions such as the reconstruction of the old city must deal with pile foundations such as "hypotento piles" near the wall, and this "hypotento piles" include vertical piles and inclined piles. The size of the existing pile driver is too large, and the pile driver and pile clamping mechanism are generally located in the middle of the pile driver. They are far away from the periphery of the pile driver, which cann...

AI Technical Summary

Problems solved by technology

The size of the existing pile driver is too large, and the pile driver and pile clamping mechanism are generally located in the middle of the pile driver. They are far away from the periphery of the pile driver, which cannot meet the construction requirements for processing hypotenuse piles, thus restricting the Popularization of prefabricated pile static pressure construction, an advanced construction method with obvious advantages in environmental protection

[0003] In the prior art, the Chinese patent with the application number CN201721600039.2 discloses a hydraulic pile driver with a variable-amplitude hydraulic pressure pile structure. Although the hydraulic pile driver can also construct "hypotenuse piles", the pile Every time the machine completes the construction work of a "hypotenosis pile", it needs to move the machine to work on the next "hypotenuse pile". Before, the hydraulic pile driver had to be re-leveled and positioned. The construction efficiency of the hypotenuse piles in the construction row was low. The time-consuming, high energy consumption and slow construction speed of moving the machine and re-leveling the hydraulic pile driver affected the construction efficiency. and cost

[0004] At the same time, the existing piling method and equipment, in the process of piling and machine moving, the safety design margin of the center of gravity change of the hydraulic pile machine is small, and it cannot be reliably guaranteed that the hydraulic pile machine will not be damaged during the pile lifting and piling process, or when there is an accident on the foundation support surface. , equipment and personnel safety
